CWTools Action

Run CWTools on your Clausewitz mod PDXScript code in parallel to your builds.

If CWTools finds errors, warnings or suggestions in the mod code then they will be output.

It will also insert them as inline feedback into your PRs ("Files changed" tab):

Setup

GitHub: Can't use GitHub? Click here for GitLab installation instructions .

In most cases, no setup is required beyond adding the following workflow yml file to your project (.github/workflows folder) and setting the correct game. See below for advanced configuration and an explanation of the tools used.

The following games require no further setup:

• HOI4
• Stellaris

Example workflow yml

name: CWTools CI

on: [pull_request, push] # other events may work but are not supported

jobs:
  cwtools_job:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1 # required
    - uses: cwtools/cwtools-action@v1.1.0
      with:
        game: hoi4
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} # required, secret is automatically set by github

This action will create a new job called "CWTools", which will be used to annotate your code. Its success or failure state depends on the CWTools output.

The full output.json log is saved to $GITHUB_WORKSPACE, and can be recovered with actions/upload-artifact.

    - uses: cwtools/cwtools-action@v1.1.0
      with:
        game: hoi4
        cache: "cache/hoi4.cwb.bz2"
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

locLanguages (optional)

GitLab

Due to limitations with GitLab, this currently only works for merge requests to master

Running this action on GitLab is a bit more involved, requiring the creation of a bot account. It is also limited to providing comments on pull requests as shown here:

Setting up the bot account

1. Create a new GitLab account for this "bot" and give it "Reporter" access to your project.
2. Log into the account, browse to the Personal Access Token page and generate a PAT with "api" scope. Make a note of the token.
3. Log back into your primary account.
4. Browse to your Project and go to "Settings", "CI / CD", and open the section "Variables".
5. Create a variable called "REVIEWDOG_GITLAB_API_TOKEN". Put the PAT generated above as the Value, then set it as "Masked" but not Protected.
6. Press "Save variables".

Please note: This PAT gives access to all projects the bot can access. If somebody gets access to your pipeline logs, it's possible (although not likely) that they could access the token.

Configuring gitlab-ci

1. In the root of your project create a file called .gitlab-ci.yml
2. Copy the contents of the example file GitLab_CWToolsCI.yml, found in /examples, into it.
3. Configure the variables if desired (see above).
4. Create a merge request and check it works!

GitLab self-hosted

If you're running your own instance of GitLab, you'll need to set the following two variables in addition to those in the default template:

 - GITLAB_API: "https://example.gitlab.com/api/v4"
 - REVIEWDOG_INSECURE_SKIP_VERIFY: true

How this works

CWTools is a .NET library that provides features to analyse and manipulate the scripting language used in Paradox Development Studio's games (PDXScript). This is mainly used in a VS Code extension, cwtools-vscode. CWTools also provides a CLI tool CWTools.CLI to allow automated anaylsis, which is what this action relies on.

This action relies on two things:

1. A set of valiation rules written for the game your mod is for
2. A cache file containing key information from vanilla files

Validation rules

The validation rules are taken from the master branch of the public repository for the game, e.g. https://github.com/cwtools/cwtools-hoi4-config. The settings rules and rulesRef can be used to specify an alternative repo, or to stay on an old version of the rules.

Vanilla cache file

In order to validate correctly, CWTools requires certain data from the vanilla game files such as defined localisation, variables, etc. There are two formats of cache file:

Metadata only

The metadata format contains a limited set of information from vanilla, enough to run the main validator. For convenience CWTools automatically generates these metadata cache files for the latest public rules and latest version of each game. These are found here and are used by default in this action (please note that not all games may be supported yet).

Full

The full format contains a more details, processed, version of the vanilla script files. This is required in order to provide accurate validation taking load order and file overrides into account. This is the same format used by cwtools-vscode. We do not provide these files, however this action can be configured to use them.
