This repository contains a set of scripts that are used by the .travis.yml and appveyor.yml files of pyvista-based packages for the Travis and AppVeyor services respectively.

These scripts help set up OpenGL related features like headless displays on the CI-services.

The idea is to clone these at the last minute when the continuous integration is about to be run. This is better than including this repository as a sub-module, because this allows updates to this repository to take effect immediately, and not have to update the sub-module every time a change is made.

Include the following lines at the start of the install section in appveyor.yml:

install:
  # configure a headless display
  - "git clone --depth 1 https://github.com/pyvista/gl-ci-helpers.git"
  - "powershell gl-ci-helpers/appveyor/install_opengl.ps1"
  - "SET PYVISTA_OFF_SCREEN=True"

Include the following in the before_script section of your .travis.yml (please note that you might have to use a xenial linux distribution)

dist: xenial
before_install:
  # configure a headless display
  - git clone --depth 1 https://github.com/pyvista/gl-ci-helpers.git
  - source ./gl-ci-helpers/travis/setup_headless_display.sh
