Step 1: Review Your Packages

Step 2: Choose Your Integration Method

Step 3: Copy Your Script or Download Config

Option 1: Copy Script

Option 2: Download Config

Step 4: Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

Option 1: Cached Package (Unreliable, Requires Internet - Same As Community)

Open Source or Commercial:
- Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
- You can also just download the packages and push them to a repository
  Download Packages

Option 2: Internalized Package (Reliable, Scalable)

Open Source
- Download the packages:
  Download Packages
- Follow manual internalization instructions
Package Internalizer (C4B)
- Run: (additional options)
- For package and dependencies run:
- Automate package internalization

Step 5: Copy Your Script

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

If Applicable - Chocolatey Configuration/Installation


## 1. REQUIREMENTS ##
### Here are the requirements necessary to ensure this is successful.

### a. Internal/Private Cloud Repository Set Up ###
#### You'll need an internal/private cloud repository you can use. These are
####  generally really quick to set up and there are quite a few options.
####  Chocolatey Software recommends Nexus, Artifactory Pro, or ProGet as they
####  are repository servers and will give you the ability to manage multiple
####  repositories and types from one server installation.

### b. Download Chocolatey Package and Put on Internal Repository ###
#### You need to have downloaded the Chocolatey package as well.
####  Please see https://chocolatey.org/install#organization

### c. Other Requirements ###

#### We initialize a few things that are needed by this script - there are no other requirements.
$ErrorActionPreference = "Stop"

#### Set TLS 1.2 (3072) as that is the minimum required by various up-to-date repositories.
#### Use integers because the enumeration value for TLS 1.2 won't exist
#### in .NET 4.0, even though they are addressable if .NET 4.5+ is
#### installed (.NET 4.5 is an in-place upgrade).
[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072

#### We use this variable for future REST calls.
$RequestArguments = @{
    UseBasicParsing = $true
}

## 2. TOP LEVEL VARIABLES ##

### a. Your internal repository url (the main one). ###
####  Should be similar to what you see when you browse
#### to https://community.chocolatey.org/api/v2/
$NugetRepositoryUrl = "INTERNAL REPO URL"

### b. Internal Repository Credential ###
#### If required, add the repository access credential here
# $NugetRepositoryCredential = [PSCredential]::new(
#     "username",
#     ("password" | ConvertTo-SecureString -AsPlainText -Force)
# )
# $RequestArguments.Credential = $NugetRepositoryCredential

### c. Chocolatey nupkg download url ###
#### This url should result in an immediate download when you navigate to it
$ChocolateyDownloadUrl = "$($NugetRepositoryUrl.TrimEnd('/'))/package/chocolatey.2.4.1.nupkg"

### d. Chocolatey Central Management (CCM) ###
#### If using CCM to manage Chocolatey, add the following:
#### i. Endpoint URL for CCM
# $ChocolateyCentralManagementUrl = "https://chocolatey-central-management:24020/ChocolateyManagementService"

#### ii. If using a Client Salt, add it here
# $ChocolateyCentralManagementClientSalt = "clientsalt"

#### iii. If using a Service Salt, add it here
# $ChocolateyCentralManagementServiceSalt = "servicesalt"

## 3. ENSURE CHOCOLATEY IS INSTALLED ##
### Ensure Chocolatey is installed from your internal repository

#### Download the Nupkg, appending .zip to the filename to handle archive cmdlet limitations
if (-not (Get-Command choco.exe -ErrorAction SilentlyContinue)) {
    $TempDirectory = Join-Path $env:Temp "chocolateyInstall"
    if (-not (Test-Path $TempDirectory -PathType Container)) {
        $null = New-Item -Path $TempDirectory -ItemType Directory
    }
    $DownloadedNupkg = Join-Path $TempDirectory "$(Split-Path $ChocolateyDownloadUrl -Leaf).zip"
    Invoke-WebRequest -Uri $ChocolateyDownloadUrl -OutFile $DownloadedNupkg @RequestArguments

    #### Extract the Nupkg, and run the chocolateyInstall script
    if (Get-Command Microsoft.PowerShell.Archive\Expand-Archive -ErrorAction SilentlyContinue) {
        Microsoft.PowerShell.Archive\Expand-Archive -Path $DownloadedNupkg -DestinationPath $TempDirectory -Force
    } else {
        # PowerShell versions <4.0 do not have this function available
        try {
            $shellApplication = New-Object -ComObject Shell.Application
            $zipPackage = $shellApplication.NameSpace($DownloadedNupkg)
            $destinationFolder = $shellApplication.NameSpace($TempDirectory)
            $destinationFolder.CopyHere($zipPackage.Items(), 0x10)
        } catch {
            Write-Warning "Unable to unzip package using built-in compression."
            throw $_
        }
    }

    & $(Join-Path $TempDirectory "tools\chocolateyInstall.ps1")
}

if (-not (Get-Command choco.exe -ErrorAction SilentlyContinue)) {
    refreshenv
}

## 4. CONFIGURE CHOCOLATEY BASELINE ##
### a. FIPS Feature ###
#### If you need FIPS compliance - make this the first thing you configure
#### before you do any additional configuration or package installations
# choco feature enable -n useFipsCompliantChecksums

### b. Apply Recommended Configuration ###
#### Move cache location so Chocolatey is very deterministic about
#### cleaning up temporary data and the location is secured to admins
choco config set --name cacheLocation --value C:\ProgramData\chocolatey\cache

#### Increase timeout to at least 4 hours
choco config set --name commandExecutionTimeoutSeconds --value 14400

#### Turn off download progress when running choco through integrations
choco feature disable --name showDownloadProgress

### c. Sources ###
#### Remove the default community package repository source
choco source list --limitoutput | ConvertFrom-Csv -Header 'Name', 'Location' -Delimiter '|' | ForEach-Object {
    if ($_.Location -eq 'https://community.chocolatey.org/api/v2/') {
        choco source remove -n $_.Name
    }
}

#### Add internal default sources
#### You could have multiple sources here, so we will provide an example
#### of one using the remote repo variable here

#### NOTE: This EXAMPLE may require changes
if ($NugetRepositoryCredential) {
    choco source add --name ChocolateyInternal --source $NugetRepositoryUrl --user $NugetRepositoryCredential.UserName --password $NugetRepositoryCredential.GetNetworkCredential().Password --priority 1
} else {
    choco source add --name ChocolateyInternal --source $NugetRepositoryUrl --priority 1
}

### b. Keep Chocolatey Up To Date ###
#### Keep chocolatey up to date based on your internal source
#### You control the upgrades based on when you push an updated version
####  to your internal repository.
#### Note the source here is to the OData feed, similar to what you see
####  when you browse to https://community.chocolatey.org/api/v2/
choco upgrade chocolatey --confirm

## 5. ENSURE CHOCOLATEY FOR BUSINESS ##
### If you don't have Chocolatey for Business (C4B), you'll want to remove from here down.

### a. Ensure The License File Is Installed ###
#### Create a license package using script from https://docs.chocolatey.org/en-us/how-tos/setup-offline-installation#exercise-4-create-a-package-for-the-license
choco install chocolatey-license --source $NugetRepositoryUrl --confirm

### b. Disable The Licensed Source ###
#### The licensed source cannot be removed, so it must be disabled.
#### This must occur after the license has been set by the license package.
if ("chocolatey-license" -in (choco list --localonly --limitoutput | ConvertFrom-Csv -Header "Name" -Delimiter "|").Name) {
    choco source disable --name chocolatey.licensed
} else {
    Write-Warning "Not disabling 'chocolatey.licensed' feed, as Chocolatey-License has not been installed."
}

### c. Ensure Chocolatey Licensed Extension ###
#### You will have downloaded the licensed extension to your internal repository
#### as you have disabled the licensed repository in step 5b.

#### Ensure the chocolatey.extension package (aka Chocolatey Licensed Extension)
if ("chocolatey-license" -in (choco list --localonly --limitoutput | ConvertFrom-Csv -Header "Name" -Delimiter "|").Name) {
    choco install chocolatey.extension --source $NugetRepositoryUrl --confirm
} else {
    Write-Warning "Not installing 'chocolatey.extension', as Chocolatey-License has not been installed."
}

#requires -Modules cChoco
## 1. REQUIREMENTS ##
### Here are the requirements necessary to ensure this is successful.

### a. Internal/Private Cloud Repository Set Up ###
#### You'll need an internal/private cloud repository you can use. These are
####  generally really quick to set up and there are quite a few options.
####  Chocolatey Software recommends Nexus, Artifactory Pro, or ProGet as they
####  are repository servers and will give you the ability to manage multiple
####  repositories and types from one server installation.

### b. Download Chocolatey Package and Put on Internal Repository ###
#### You need to have downloaded the Chocolatey package as well.
####  Please see https://chocolatey.org/install#organization

### c. Other Requirements ###
#### i. Requires chocolatey\cChoco DSC module to be installed on the machine compiling the DSC manifest
#### NOTE: This will need to be installed before running the DSC portion of this script
if (-not (Get-Module cChoco -ListAvailable)) {
    $null = Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
    if (($PSGallery = Get-PSRepository -Name PSGallery).InstallationPolicy -ne "Trusted") {
        Set-PSRepository -Name PSGallery -InstallationPolicy Trusted
    }
    Install-Module -Name cChoco
    if ($PSGallery.InstallationPolicy -ne "Trusted") {
        Set-PSRepository -Name PSGallery -InstallationPolicy $PSGallery.InstallationPolicy
    }
}

#### ii. Requires a hosted copy of the install.ps1 script
##### This should be available to download without authentication.
##### The original script can be found here: https://community.chocolatey.org/install.ps1

Configuration ChocolateyConfig {
## 2. TOP LEVEL VARIABLES ##
    param(
### a. Your internal repository url (the main one). ###
####  Should be similar to what you see when you browse
#### to https://community.chocolatey.org/api/v2/
        $NugetRepositoryUrl      = "INTERNAL REPO URL",

### b. Chocolatey nupkg download url ###
#### This url should result in an immediate download when you navigate to it in
#### a web browser
        $ChocolateyNupkgUrl      = "INTERNAL REPO URL/package/chocolatey.2.4.1.nupkg",

### c. Internal Repository Credential ###
#### If required, add the repository access credential here
#        $NugetRepositoryCredential = [PSCredential]::new(

## 3. ENSURE CHOCOLATEY IS INSTALLED ##
### Ensure Chocolatey is installed from your internal repository
        Environment chocoDownloadUrl {
            Name  = "chocolateyDownloadUrl"
            Value = $ChocolateyNupkgUrl
        }

            InstallDir = Join-Path $env:ProgramData "chocolatey"
            ChocoInstallScriptUrl = $ChocolateyInstallPs1Url
        }

## 4. CONFIGURE CHOCOLATEY BASELINE ##
### a. FIPS Feature ###
#### If you need FIPS compliance - make this the first thing you configure
#### before you do any additional configuration or package installations
#        cChocoFeature featureFipsCompliance {
#            FeatureName = "useFipsCompliantChecksums"
#        }

### b. Apply Recommended Configuration ###

#### Move cache location so Chocolatey is very deterministic about
#### cleaning up temporary data and the location is secured to admins
        cChocoConfig cacheLocation {
            DependsOn  = "[cChocoInstaller]installChocolatey"
            ConfigName = "cacheLocation"
            Value      = "C:\ProgramData\chocolatey\cache"
        }

#### Increase timeout to at least 4 hours
        cChocoConfig commandExecutionTimeoutSeconds {
            DependsOn  = "[cChocoInstaller]installChocolatey"
            ConfigName = "commandExecutionTimeoutSeconds"
            Value      = 14400
        }

#### Turn off download progress when running choco through integrations
        cChocoFeature showDownloadProgress {
            DependsOn   = "[cChocoInstaller]installChocolatey"
            FeatureName = "showDownloadProgress"
            Ensure      = "Absent"
        }

### c. Sources ###
#### Remove the default community package repository source
        cChocoSource removeCommunityRepository {
            DependsOn  = "[cChocoInstaller]installChocolatey"
            Name       = "chocolatey"
            Ensure     = "Absent"
        }

#### Add internal default sources
#### You could have multiple sources here, so we will provide an example
#### of one using the remote repo variable here.
#### NOTE: This EXAMPLE may require changes
        cChocoSource addInternalSource {
            DependsOn  = "[cChocoInstaller]installChocolatey"
            Name        = "ChocolateyInternal"

            Credentials = $NugetRepositoryCredential
            Priority    = 1
        }

### b. Keep Chocolatey Up To Date ###
#### Keep chocolatey up to date based on your internal source
#### You control the upgrades based on when you push an updated version
####  to your internal repository.
#### Note the source here is to the OData feed, similar to what you see
####  when you browse to https://community.chocolatey.org/api/v2/
        cChocoPackageInstaller updateChocolatey {
            DependsOn   = "[cChocoSource]addInternalSource", "[cChocoSource]removeCommunityRepository"

        cChocoPackageInstaller chocolateyLicense {
            DependsOn = "[cChocoPackageInstaller]updateChocolatey"
            Name      = "chocolatey-license"
        }

### b. Disable The Licensed Source ###
#### The licensed source cannot be removed, so it must be disabled.
#### This must occur after the license has been set by the license package.
        Script disableLicensedSource {
            DependsOn  = "[cChocoPackageInstaller]chocolateyLicense"

2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

Option 1: Cached Package (Unreliable, Requires Internet - Same As Community)

Open Source or Commercial:
- Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
- You can also just download the package and push it to a repository Download

Option 2: Internalized Package (Reliable, Scalable)

Open Source
- Download the package:
  Download
- Follow manual internalization instructions

Package Internalizer (C4B)

Run: (additional options)

choco download sass --internalize --version=1.80.6 --source=https://community.chocolatey.org/api/v2/

For package and dependencies run:

choco push --source="'INTERNAL REPO URL'"

Automate package internalization

3. Copy Your Script

choco upgrade sass -y --source="'INTERNAL REPO URL'" --version="'1.80.6'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade sass -y --source="'INTERNAL REPO URL'" --version="'1.80.6'" 
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0
}

Exit $exitCode

Description

Sass makes CSS fun again. Sass is an extension of CSS, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.

This package is Dart Sass, the new Dart implementation of Sass.

      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent

      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

                           Version 2.0, January 2004
                        http://www.apache.org/licenses/

   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

   1. Definitions.

      "License" shall mean the terms and conditions for use, reproduction,
      and distribution as defined by Sections 1 through 9 of this document.

      "Licensor" shall mean the copyright owner or entity authorized by
      the copyright owner that is granting the License.

      "Legal Entity" shall mean the union of the acting entity and all
      other entities that control, are controlled by, or are under common
      control with that entity. For the purposes of this definition,
      "control" means (i) the power, direct or indirect, to cause the
      direction or management of such entity, whether by contract or
      otherwise, or (ii) ownership of fifty percent (50%) or more of the
      outstanding shares, or (iii) beneficial ownership of such entity.

      "You" (or "Your") shall mean an individual or Legal Entity
      exercising permissions granted by this License.

      "Source" form shall mean the preferred form for making modifications,
      including but not limited to software source code, documentation
      source, and configuration files.

      "Object" form shall mean any form resulting from mechanical
      transformation or translation of a Source form, including but
      not limited to compiled object code, generated documentation,
      and conversions to other media types.

      "Work" shall mean the work of authorship, whether in Source or
      Object form, made available under the License, as indicated by a
      copyright notice that is included in or attached to the work
      (an example is provided in the Appendix below).

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain
      separable from, or merely link (or bind by name) to the interfaces of,
      the Work and Derivative Works thereof.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions
      to that Work or Derivative Works thereof, that is intentionally
      submitted to Licensor for inclusion in the Work by the copyright owner
      or by an individual or Legal Entity authorized to submit on behalf of
      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent
      to the Licensor or its representatives, including but not limited to
      communication on electronic mailing lists, source code control systems,
      and issue tracking systems that are managed by, or on behalf of, the
      Licensor for the purpose of discussing and improving the Work, but
      excluding communication that is conspicuously marked or otherwise
      designated in writing by the copyright owner as "Not a Contribution."

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and
      subsequently incorporated within the Work.

   2. Grant of Copyright License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      copyright license to reproduce, prepare Derivative Works of,
      publicly display, publicly perform, sublicense, and distribute the
      Work and such Derivative Works in Source or Object form.

   3. Grant of Patent License. Subject to the terms and conditions of
      this License, each Contributor hereby grants to You a perpetual,
      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS

   APPENDIX: How to apply the Apache License to your work.

ways:

1. Instead of being created by [a parser], it's created by [the evaluator] as it
   traverses the [Sass AST].

   [a parser]: ../../parse/README.md
   [the evaluator]: ../../visitor/async_evaluate.dart
   [Sass AST]: ../sass/README.md

2. Because of various Sass features like `@extend` and at-rule hoisting, the CSS
   AST is mutable even though all other ASTs are immutable.

**Note:** the CSS AST doesn't have its own representation of declaration values.
Instead, declaration values are represented as [`Value`] objects. This does mean
that a CSS AST can be in a state where some of its values aren't representable
in plain CSS (such as maps)—in this case, [the serializer] will emit an error.

[`Value`]: ../../value/README.md
[the serializer]: ../../visitor/serialize.dart

## Mutable and Immutable Views

Internally, the CSS AST is mutable to allow for operations like hoisting rules
to the root of the AST and updating existing selectors when `@extend` rules are
encountered. However, because mutability poses a high risk for "spooky [action
at a distance]", we limit access to mutating APIs exclusively to the evaluator.

[action at a distance]: https://en.wikipedia.org/wiki/Action_at_a_distance_(computer_programming)

We do this by having an _unmodifiable_ interface (written in this directory) for
each CSS AST node which only exposes members that don't modify the node in
question. The implementations of those interfaces, which _do_ have modifying
methods, live in the [`modifiable`] directory. We then universally refer to the
immutable node interfaces except specifically in the evaluator, and the type
system automatically ensures we don't accidentally mutate anything we don't
intend to.

[`modifiable`]: modifiable

(Of course, it's always possible to cast an immutable node type to a mutable
one, but that's a very clear code smell that a reviewer can easily identify.)

## CSS Source Files

A lesser-known fact about Sass is that it actually supports _three_ syntaxes for
its source files: SCSS, the indented syntax, and plain CSS. But even when it
parses plain CSS, it uses the Sass AST rather than the CSS AST to represent it
so that parsing logic can easily be shared with the other stylesheet parsers.

# Sass Abstract Syntax Tree

This directory contains the abstract syntax tree that represents a Sass source
file, regardless of which syntax it was written in (SCSS, the indented syntax,
or plain CSS). The AST is constructed recursively by [a parser] from the leaf
nodes in towards the root, which allows it to be fully immutable.

[a parser]: ../../parse/README.md

The Sass AST is broken up into three categories:

1. The [statement AST], which represents statement-level constructs like
   variable assignments, style rules, and at-rules.

   [statement AST]: statement

2. The [expression AST], which represents SassScript expressions like function
   calls, operations, and value literals.

   [expression AST]: exprssion

3. Miscellaneous AST nodes that are used by both statements and expressions or
   don't fit cleanly into either category that live directly in this directory.

The Sass AST nodes are processed (usually from the root [`Stylesheet`]) by [the
evaluator], which runs the logic they encode and builds up a [CSS AST] that
represents the compiled stylesheet. They can also be transformed back into Sass
source using the `toString()` method. Since this is only ever used for debugging
and doesn't need configuration or full-featured indentation tracking, it doesn't
use a full visitor.

# Selector Abstract Syntax Tree

This directory contains the abstract syntax tree that represents a parsed CSS
selector. This AST is constructed recursively by [the selector parser]. It's
fully immutable.

[the selector parser]: ../../parse/selector.dart

Unlike the [Sass AST], which is parsed from a raw source string before being
evaluated, the selector AST is parsed _during evaluation_. This is necessary to
ensure that there's a chance to resolve interpolation before fully parsing the
selectors in question.

[Sass AST]: ../sass/README.md

Although this AST doesn't include any SassScript, it _does_ include a few
Sass-specific constructs: the [parent selector] `&` and [placeholder selectors].
Parent selectors are resolved by [the evaluator] before it hands the AST off to
[the serializer], while placeholders are omitted in the serializer itself.

# Embedded Sass Compiler

This directory contains the Dart Sass embedded compiler. This is a special mode
of the Dart Sass command-line executable, only supported on the Dart VM, in
which it uses stdin and stdout to communicate with another endpoint, the
"embedded host", using a protocol buffer-based protocol. See [the embedded
protocol specification] for details.

[the embedded protocol specification]: https://github.com/sass/sass/blob/main/spec/embedded-protocol.md

The embedded compiler has two different levels of dispatchers for handling
incoming messages from the embedded host:

1. The [`IsolateDispatcher`] is the first recipient of each packet. It decodes
   the packets _just enough_ to determine which compilation they belong to, and
   forwards them to the appropriate compilation dispatcher. It also parses and
   handles messages that aren't compilation specific, such as `VersionRequest`.

   [`IsolateDispatcher`]: isolate_dispatcher.dart

2. The [`CompilationDispatcher`] fully parses and handles messages for a single
   compilation. Each `CompilationDispatcher` runs in a separate isolate so that
   the embedded compiler can run multiple compilations in parallel.

   [`CompilationDispatcher`]: compilation_dispatcher.dart

Otherwise, most of the code in this directory just wraps Dart APIs to
communicate with their protocol buffer equivalents.

# `@extend` Logic

This directory contains most of the logic for running Sass's `@extend` rule.
This rule is probably the most complex corner of the Sass language, since it
involves both understanding the semantics of selectors _and_ being able to
combine them.

The high-level lifecycle of extensions is as follows:

1. When [the evaluator] encounters a style rule, it registers its selector in
   the [`ExtensionStore`] for the current module. This applies any extensions
   that have already been registered, then returns a _mutable_
   `Box<SelectorList>` that will get updated as extensions are applied.

   [the evaluator]: ../visitor/async_evaluate.dart
   [`ExtensionStore`]: extension_store.dart

2. When the evaluator encounters an `@extend`, it registers that in the current
   module's `ExtensionStore` as well. This updates any selectors that have
   already been registered with that extension, _and_ updates the extension's
   own extender (the selector that gets injected when the extension is applied,
   which is stored along with the extension). Note that the extender has to be
   extended separately from the selector in the style rule, because the latter
   gets redundant selectors trimmed eagerly and the former does not.

3. When the entrypoint stylesheet has been fully executed, the evaluator
   determines which extensions are visible from which modules and adds
   extensions from one store to one another accordingly using
   `ExtensionStore.addExtensions()`.

Otherwise, the process of [extending a selector] as described in the Sass spec
matches the logic here fairly closely. See `ExtensionStore._extendList()` for
the primary entrypoint for that logic.

# Built-In Functions

This directory contains the standard functions that are built into Sass itself,
both those that are available globally and those that are available only through
built-in modules. Each of the files here exports a corresponding
[`BuiltInModule`], and most define a list of global functions as well.

[`BuiltInModule`]: ../module/built_in.dart

There are a few functions that Sass supports that aren't defined here:

* The `if()` function is defined directly in the [`functions.dart`] file,
  although in most cases this is actually parsed as an [`IfExpression`] and
  handled directly by [the evaluator] since it has special behavior about when
  its arguments are evaluated. The function itself only exists for edge cases
  like `if(...$args)` or `meta.get-function("if")`.

  [`functions.dart`]: ../functions.dart
  [`IfExpression`]: ../ast/sass/expression/if.dart
  [the evaluator]: ../visitor/async_evaluate.dart

* Certain functions in the `sass:meta` module require runtime information that's
  only available to the evaluator. These functions are defined in the evaluator
  itself so that they have access to its private variables.

# Input/Output Shim

This directory contains an API shim for doing various forms of IO across
different platforms. Dart chooses at compile time which of the three files to
use:

* `interface.dart` is used by the Dart Analyzer for static checking. It defines
  the "expected" interface of the other two files, although there aren't strong
  checks that their interfaces are exactly the same.

* `vm.dart` is used by the Dart VM, and defines IO operations in terms of the
  `dart:io` library.

* `js.dart` is used by JS platforms. On Node.js, it will use Node's `fs` and
  `process` APIs for IO operations. On other JS platforms, most IO operations
  won't work at all, although messages will still be emitted with
  `console.log()` and `console.error()`.

# JavaScript API

This directory contains Dart Sass's implementation of the Sass JS API. Dart's JS
interop support is primarily intended for _consuming_ JS libraries from Dart, so
we have to jump through some hoops in order to effectively _produce_ a JS
library with the desired API.

JS support has its own dedicated entrypoint in [`../js.dart`]. The [`cli_pkg`
package] ensures that when users load Dart Sass _as a library_, this entrypoint
is run instead of the CLI entrypoint, but otherwise it's up to us to set up the
library appropriately. To do so, we use JS interop to define an [`Exports`]
class that is in practice implemented by a CommonJS-like[^1] `exports` object,
and then assign various values to this object.

[`../js.dart`]: ../js.dart
[`cli_pkg` package]: https://github.com/google/dart_cli_pkg
[`Exports`]: exports.dart

[^1]: It's not _literally_ CommonJS because it needs to run directly on browsers
      as well, but it's still an object named `exports` that we can hang names
      off of.

## Value Types

The JS API value types pose a particular challenge from Dart. Although every
Dart class is represented by a JavaScript class when compiled to JS, Dart has no
way of specifying what the JS API of those classes should be. What's more, in
order to make the JS API as efficient as possible, we want to be able to pass
the existing Dart [`Value`] objects as-is to custom functions rather than
wrapping them with JS-only wrappers.

[`Value`]: ../value.dart

To solve the first problem, in [`reflection.dart`] we use JS interop to wrap the
manual method of defining a JavaScript class. We use this to create a
JS-specific class for each value type, with all the JS-specific methods and
properties defined by Sass's JS API spec. However, while normal JS constructors
just set some properties on `this`, our constructors for these classes return
Dart `Value` objects instead.

[`reflection.dart`]: reflection.dart

"But wait," I hear you say, "those `Value` objects aren't instances of the new
JS class you've created!" This is where the deep magic comes in. Once we've
defined our class with its phony constructor, we create a single Dart object of
the given `Value` subclass and _edit its JavaScript prototype chain_ to include
the new class we just created. Once that's done, all the Dart value types will
have exactly the right JS API (including responding correctly to `instanceof`!)
and the constructor will now correctly return an instance of the JS class.

## Legacy API

Dart Sass also supports the legacy JS API in the [`legacy`] directory. This hews
as close as possible to the API of the old `node-sass` package which wrapped the
old LibSass implementation. It's no longer being actively updated, but we still
need to support it at least until the next major version release of Dart Sass.

# Sass Parser

This directory contains various parsers used by Sass. The two most relevant
classes are:

* [`Parser`]: The base class of all other parsers, which includes basic
  infrastructure, utilities, and methods for parsing common CSS constructs that
  appear across multiple different specific parsers.

  [`Parser`]: parser.dart

* [`StylesheetParser`]: The base class specifically for the initial stylesheet
  parse. Almost all of the logic for parsing Sass files, both statement- and
  expression-level, lives here. Only places where individual syntaxes differ
  from one another are left abstract or overridden by subclasses.

  [`StylesheetParser`]: stylesheet.dart

All Sass parsing is done by hand using the [`string_scanner`] package, which we
use to read the source [code-unit]-by-code-unit while also tracking source span
information which we can then use to report errors and generate source maps. We
don't use any kind of parser generator, partly because Sass's grammar requires
arbitrary backtracking in various places and partly because handwritten code is
often easier to read and debug.

[`string_scanner`]: https://pub.dev/packages/string_scanner
[code-unit]: https://developer.mozilla.org/en-US/docs/Glossary/Code_unit

The parser is simple recursive descent. There's usually a method for each
logical production that either consumes text and returns its corresponding AST
node or throws an exception; in some cases, a method (conventionally beginning
with `try`) will instead consume text and return a node if it matches and return
null without consuming anything if it doesn't.

  contain some logic to drive the basic compilation logic and handle errors. All
  the most complex parts of the CLI, such as option parsing and the `--watch`
  command, are handled in the [`executable`] directory. Even Embedded Sass runs
  through this entrypoint, although it gets immediately gets handed off to [the
  embedded compiler].

  [`../../bin/sass.dart`]: ../../bin/sass.dart
  [`executable`]: executable
  [the embedded compiler]: embedded/README.md

* [`../sass.dart`] is the entrypoint for the public Dart API. This is what's
  loaded when a Dart package imports Sass. It just contains the basic
  compilation functions, and exports the rest of the public APIs from this
  directory.

  [`../sass.dart`]: ../sass.dart

Everything else is contained here, and each file and some subdirectories have
their own documentation. But before you dive into those, let's take a look at
the general lifecycle of a Sass compilation.

## Life of a Compilation

Whether it's invoked through the Dart API, the JS API, the CLI, or the embedded
host, the basic process of a Sass compilation is the same. Sass is implemented
as an AST-walking [interpreter] that operates in roughly three passes:

[interpreter]: https://en.wikipedia.org/wiki/Interpreter_(computing)

1. **Parsing**. The first step of a Sass compilation is always to parse the
   source file, whether it's SCSS, the indented syntax, or CSS. The parsing
   logic lives in the [`parse`] directory, while the abstract syntax tree that
   represents the parsed file lives in [`ast/sass`].

   [`parse`]: parse/README.md
   [`ast/sass`]: ast/sass/README.md

2. **Evaluation**. Once a Sass file is parsed, it's evaluated by
   [`visitor/async_evaluate.dart`]. (Why is there both an async and a sync
   version of this file? See [Synchronizing] for details!) The evaluator handles
   all the Sass-specific logic: it resolves variables, includes mixins, executes
   control flow, and so on. As it goes, it builds up a new AST that represents
   the plain CSS that is the compilation result, which is defined in
   [`ast/css`].

   [`visitor/async_evaluate.dart`]: visitor/async_evaluate.dart
   [Synchronizing]: ../../CONTRIBUTING.md#synchronizing
   [`ast/css`]: ast/css/README.md

   Sass evaluation is almost entirely linear: it begins at the first statement
   of the file, evaluates it (which may involve evaluating its nested children),
   adds its result to the CSS AST, and then moves on to the second statement. On
   it goes until it reaches the end of the file, at which point it's done. The
   only exception is module resolution: every Sass module has its own compiled
   CSS AST, and once the entrypoint file is done compiling the evaluator will go
   back through these modules, resolve `@extend`s across them as necessary, and
   stitch them together into the final stylesheet.

   SassScript, the expression-level syntax, is handled by the same evaluator.
   The main difference between SassScript and statement-level evaluation is that
   the same SassScript values are used during evaluation _and_ as part of the
   CSS AST. This means that it's possible to end up with a Sass-specific value,
   such as a map or a first-class function, as the value of a CSS declaration.
   If that happens, the Serialization phase will signal an error when it
   encounters the invalid value.

3. **Serialization**. Once we have the CSS AST that represents the compiled
   stylesheet, we need to convert it into actual CSS text. This is done by
   [`visitor/serialize.dart`], which walks the AST and builds up a big buffer of
   the resulting CSS. It uses [a special string buffer] that tracks source and
   destination locations in order to generate [source maps] as well.

   [`visitor/serialize.dart`]: visitor/serialize.dart
   [a special string buffer]: util/source_map_buffer.dart
   [source maps]: https://web.dev/source-maps/

There's actually one slight complication here: the first and second pass aren't
as separate as they appear. When one Sass stylesheet loads another with `@use`,
`@forward`, or `@import`, that rule is handled by the evaluator and _only at
that point_ is the loaded file parsed. So in practice, compilation actually
switches between parsing and evaluation, although each individual stylesheet
naturally has to be parsed before it can be evaluated.

### Late Parsing

Some syntax within a stylesheet is only parsed _during_ evaluation. This allows
authors to use `#{}` interpolation to inject Sass variables and other dynamic
values into various locations, such as selectors, while still allowing Sass to
parse them to support features like nesting and `@extend`. The following
syntaxes are parsed during evaluation:

* [Selectors](parse/selector.dart)
* [`@keyframes` frames](parse/keyframe_selector.dart)
* [Media queries](parse/media_query.dart) (for historical reasons, these are
  parsed before evaluation and then _reparsed_ after they've been fully
  evaluated)

### Early Serialization

There are also some cases where the evaluator can serialize values before the
main serialization pass. For example, if you inject a variable into a selector
using `#{}`, that variable's value has to be converted to a string during
evaluation so that the evaluator can then parse and handle the newly-generated
selector. The evaluator does this by invoking the serializer _just_ for that
specific value. As a rule of thumb, this happens anywhere interpolation is used
in the original stylesheet, although there are a few other circumstances as
well.

## JS Support

One of the main benefits of Dart as an implementation language is that it allows
us to distribute Dart Sass both as an extremely efficient stand-alone executable
_and_ an easy-to-install pure-JavaScript package, using the dart2js compilation
tool. However, properly supporting JS isn't seamless. There are two major places
where we need to think about JS support:

1. When interfacing with the filesystem. None of Dart's IO APIs are natively
   supported on JS, so for anything that needs to work on both the Dart VM _and_
   Node.js we define a shim in the [`io`] directory that will be implemented in
   terms of `dart:io` if we're running on the Dart VM or the `fs` or `process`
   modules if we're running on Node. (We don't support IO at all on the browser
   except to print messages to the console.)

   [`io`]: io/README.md

2. When exposing an API. Dart's JS interop is geared towards _consuming_ JS
   libraries from Dart, not producing a JS library written in Dart, so we have
   to jump through some hoops to make it work. This is all handled in the [`js`]
   directory.

   [`js`]: js/README.md

## APIs

One of Sass's core features is its APIs, which not only compile stylesheets but
also allow users to provide plugins that can be invoked from within Sass. In
both the JS API, the Dart API, and the embedded compiler, Sass provides three
types of plugins: importers, custom functions, and loggers.

### Importers

Importers control how Sass loads stylesheets through `@use`, `@forward`, and
`@import`. Internally, _all_ stylesheet loads are modeled as importers. When a
user passes a load path to an API or compiles a stylesheet through the CLI, we
just use the built-in [`FilesystemImporter`] which implements the same interface
that we make available to users.

[`FilesystemImporter`]: importer/filesystem.dart

In the Dart API, the importer root class is [`importer/async_importer.dart`].
The JS API and the embedded compiler wrap the Dart importer API in
[`importer/node_to_dart`] and [`embedded/importer`] respectively.

[`importer/async_importer.dart`]: importer/async_importer.dart
[`importer/node_to_dart`]: importer/node_to_dart
[`embedded/importer`]: embedded/importer

### Custom Functions

Custom functions are defined by users of the Sass API but invoked by Sass
stylesheets. To a Sass stylesheet, they look like any other built-in function:
users pass SassScript values to them and get SassScript values back. In fact,
all the core Sass functions are implemented using the Dart custom function API.

Because custom functions take and return SassScript values, that means we need
to make _all_ values available to the various APIs. For Dart, this is
straightforward: we need to have objects to represent those values anyway, so we
just expose those objects publicly (with a few `@internal` annotations here and
there to hide APIs we don't want users relying on). These value types live in
the [`value`] directory.

[`value`]: value/README.md

Exposing values is a bit more complex for other platforms. For the JS API, we do
a bit of metaprogramming in [`js/value`] so that we can return the
same Dart values we use internally while still having them expose a JS API that
feels native to that language. For the embedded host, we convert them to and
from a protocol buffer representation in [`embedded/protofier.dart`].

[`js/value`]: js/value/README.md
[`embedded/value.dart`]: embedded/value.dart

### Loggers

Loggers are the simplest of the plugins. They're just callbacks that are invoked
any time Dart Sass would emit a warning (from the language or from `@warn`) or a
debug message from `@debug`. They're defined in:

* [`logger.dart`](logger.dart) for Dart
* [`js/logger.dart`](js/logger.dart) for Node
* [`embedded/logger.dart`](embedded/logger.dart) for the embedded compiler

## Built-In Functions

All of Sass's built-in functions are defined in the [`functions`] directory,
including both global functions and functions defined in core modules like
`sass:math`. As mentioned before, these are defined using the standard custom
function API, although in a few cases they use additional private features like
the ability to define multiple overloads of the same function name.

[`functions`]: functions/README.md

## `@extend`

The logic for Sass's `@extend` rule is particularly complex, since it requires
Sass to not only parse selectors but to understand how to combine them and when
they can be safely optimized away. Most of the logic for this is contained
within the [`extend`] directory.

[`extend`]: extend/README.md

# Value Types

This directory contains definitions for all the SassScript value types. These
definitions are used both to represent SassScript values internally and in the
public Dart API. They are usually produced by [the evaluator] as it evaluates
the expression-level [Sass AST].

[the evaluator]: ../visitor/async_evaluate.dart
[Sass AST]: ../ast/sass/README.md

Sass values are always immutable, even internally. Any changes to them must be
done by creating a new value. In some cases, it's easiest to make a mutable
copy, edit it, and then create a new immutable value from the result.

# Visitors

This directory contains various types that implement the [visitor pattern] for
[various ASTs]. A few of these, such as [the evaluator] and [the serializer],
implement critical business logic for the Sass compiler. Most of the rest are
either small utilities or base classes for small utilities that need to run over
an AST to determine some kind of information about it. Some are even entirely
unused within Sass itself, and exist only to support users of the [`sass_api`]
package.
