Concourse CI YAML Editor for Atom

macOS Build Status Windows Build Status Dependency Status

This extension provides basic validation, content assist and hover infos for editing Concourse Pipeline and Task Configuration Files.

It is recommended to use this extension package when atom-ide-ui atom extension package is installed. Thus, reconciling (error/warning markers) and hover support is fully functional.

  • Open the file, and it will most likely open with the default Atom YAML editor.
  • In the bottom-right of the editor, click on YAML.
  • This opens the Grammar Selection dialogue. Search and select Concourse-Pipeline-YAML for pipeline files, or Concourse-Task-YAML for task files.

If you find an issue please raise it here:



(Requires atom-ide-ui package) As you type the file is parsed and checked for basic syntactic and structural correctness. Hover over an error marker to see an explanation.
