A Visual Studio Code extension that provides language support for Cylc workflow configuration files.
Syntax highlighting:
- Cylc 7
- Cylc 8
- ISO 8601 datetimes
- Jinja2 (can be used with a Jinja extension e.g. Better Jinja)
Check here for info on supported syntax features.
Either:
- In VSCode, go to
View > Extensionsand search for "Cylc" - Or install from the Visual Studio Marketplace
Please report any syntax highlighting issues at cylc/cylc-textmate-grammar. Any other issues with the extension should be reported here.
This repo includes the cylc/cylc-textmate-grammar repo as a git submodule in the /syntaxes/ directory. If you don't have experience with submodules, you should read the docs first.
The cylc-textmate-grammar repo contains a JSON TextMate grammar file which is used by VSCode for syntax highlighting. Read the VSCode syntax highlight guide for more information. Note: do not edit the JSON file when contributing; instead you should edit the JavaScript grammar file and build it, as explained in the contributing section of cylc-texmate-grammar.
To install a development version of this extension:
git clone --recurse-submodules https://github.com/cylc/vscode-cylc.git
The --recurse-submodules option automatically initialises the cylc-textmate-grammar repo in the /syntaxes directory.
Run/debug the development version in a new window by pressing F5.
You can then edit the /syntaxes/src/cylc.tmLanguage.js grammar file. First, read the contributing section of the cylc-textmate-grammar repo - any such edits will be part of that repo as opposed to this vscode-cylc repo. After editing & saving the file, there is a build shortcut task (in /.vscode/tasks.json) which can be triggered by Ctrl+Shift+B. This will run the cylc-textmate-grammar build script which compiles the JSON grammar file. Reload the debugging window using the button on the toolbar or Ctrl+Shift+F5
Contributions to VSCode-specific features, e.g. bracket matching or snippets, are to be made in this repo, not the submodule.
