Deployment Method: Individual Install, Upgrade, & Uninstall

To install HP-GL Viewer, run the following command from the command line or from PowerShell:


To upgrade HP-GL Viewer, run the following command from the command line or from PowerShell:


To uninstall HP-GL Viewer, run the following command from the command line or from PowerShell:


Deployment Method:


This applies to both open source and commercial editions of Chocolatey.

1. Enter Your Internal Repository Url

(this should look similar to https://community.chocolatey.org/api/v2/)

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

  • 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

3. Copy Your Script

choco upgrade hpglviewer -y --source="'INTERNAL REPO URL'" [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 hpglviewer -y --source="'INTERNAL REPO URL'" 

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

Exit $exitCode

The HP-GL viewer developed at CERN provides fast and accurate display of HP-GL and HP-GL/2 files on a number of platforms and operating systems. It has an intuitive graphical interface and can be used to display, print, and convert files from HP-GL and HP-GL/2 to PostScript, Encapsulated PostScript, DXF, or CGM. It is available for various Unix, PC-Windows and MacIntosh platforms.

                  Viewer and converter for HP-GL files

                             Version 5.43

                       CERN, Geneva, December 2011

3. General Information

The CERN HP-GL viewer is designed to display legal HP-GL and HP-GL/2 files
on screen and to allow printing them and converting them to other formats.
The primary design criteria have been correctness, speed, and portability
to various platforms.  Versions of the viewer run on Microsoft Windows
versions 95 and newer, Apple MacOS 8 and newer, and on various Unix variants
including IBM AIX, Compaq/Digital OSF/1, Hewlett-Packard HP-UX, SGI IRIX,
Linux, Sun Solaris, and Apple MaxOS X / Darwin.  The current version of the
viewer understands most of the old HP-GL and the current HP-GL/2 standards
and extensions with a few exceptions:

  - No support for the Dual-Context Extension, i.e., using raster commands
    belonging to HP RTL (Raster Transfer Language) or HP PCL (Printer Control
    Language) command sets, or using the Scalable or Bitmap Fonts command
    sets.  Such commands are syntactically parsed and skipped without
    interpreting them.

  - HP PJL (Printer Job Language) headers are parsed and skipped.  The only
    feature interpreted is the language mode (HPGL / HPGL2), which may,
    however, be overridden if the file is later found to contain commands
    belonging solely to the other mode.

  - Minimal support for built-in fonts.  The HP-GL/2 symbol sets supported
    are:  US ASCII, Roman Extensions, Roman8, Latin1, Latin2, Latin5, and
    HP-GL Drafting.  The only available typeface is the simple vector stick
    font.  No other font characteristics are supported.

  - No support for device output and control commands in the Technical
    Graphics Extension.

  - No support for the commands in the Digitizing Extension.

  - No support for configurable line attributes, i.e., different line ends
    and joins.

  - Minimal support for advanced merge control and pixel placement commands
    in the Advanced Drawing Extension.  The merge commands are propagated
    when saving the file in HP-GL/2 from the viewer but are not interpreted
    for screen display or for printing on non-HP-GL/2 printers.

Practice has shown that few plot files heavily utilize features outside of
the set currently supported by the viewer.  However, in the future most of
the above items are expected to be supported with the exception of device
control and digitizing commands, which make no sense in the viewer context.

4. New and Changed Features in Version 5.43
Version 5.43 is a bugfix version based on version 5.42 and as such contains
no new features.

5. Old Licence Files and Version 5.43

Information in this section concerns only existing licensees of the CERN
HP-GL viewer.

Version 5.43 of the viewer is compatible with the licence files of versions
5.00, 5.01, 5.20, 5.21, 5.22, 5.30, 5.40, 5.41, and 5.42.  However, since several
items present in the licence file have been updated, it is highly recommended
to convert the file to the new format.  Note also that a bug exist in licence
files created before 2000, which renders the file unusable.  In this case
a new licence file can be requested from CERN (see below for contact details).
This can be done with the small utility named licconv available for different
architectures via the URL:


Usage instructions for the converter are contained in the included ReadMe

6. Old Configuration Files and Version 5.43

Version 5.43 of the viewer is able to read old configuration files of versions
earlier than 5.43 but it only saves them in the new format, which may not be
properly interpreted by older viewer versions.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).
