Log2CheckStyle

Convert a log to another format for easy integration with GitHub Actions, continuous integration pipelines and other purposes.

Features

  • Converts messages to Checkstyle XML format.
  • Supports specifying input and output files.
  • Allows specifying a root directory to remove from file paths.
  • Provides options for GitHub Action integration (annotations).
  • Handful as a standalone command-line tool (logToCs.py).

Usage

Command Line Interface

logToCs.py [OPTIONS] [INPUT [OUTPUT]]

OPTIONS

Convert messages to Checkstyle XML format.

positional arguments:
  input                 Input file. Use '-' or omit for stdin.
  output                Output file. Use '-' or omit for stdout.

optional arguments:
  -h, --help            show this help message and exit
  -i INPUT_NAMED, --in INPUT_NAMED
                        Input filename. Overrides positional input.
  -o OUTPUT_NAMED, --out OUTPUT_NAMED
                        Output filename. Overrides positional output.
  --root ROOT_PATH      Root directory to remove from file paths. Defaults to
                        working directory.
  --github-annotate, --no-github-annotate
                        Annotate when in Github workflow. (default: False)
  --gitlab, --no-gitlab
                        Generate gitlab report (artefact) when in Gitlab workflow. (default: False)
  --name-only, --no-name-only
                        Report filenames only. (default: False)

GitHub Action

Using No Extra Resources:

  - name: Convert Raw Log to Checkstyle format (launch action)
    uses: mdeweerd/[email protected]
    if: ${{ failure() }}
    with:
      in: ${{ env.RAW_LOG }}
      # Out can be omitted if you do not need the xml output
      out: ${{ env.CS_XML }}

The above extracts the notifications from the RAW_LOG, writes a file in CheckStyle format and applies source code annotations for a Github Pull Request.

For a full example, see the precommit github workflow for this project.

Using local resources

Convert the output from an action to CheckStyle xml and convert that to GitHub Annotations using a different action.

These examples assume that logToCs.py is available as .github/logToCs.py.

Example 1:

Use other action to generate the GitHub annotations.

  - run: |
      pre-commit run -all-files | tee pre-commit.log
      .github/logToCs.py pre-commit.log pre-commit.xml
  - uses: staabm/annotate-pull-request-from-checkstyle-action@v1
    with:
      files: pre-commit.xml
      notices-as-warnings: true     # optional
Example 2 (old):

Use cs2pr commands to generate the GitHub annotations.

  - run: |
      pre-commit run --all-files | tee pre-commit.log
  - name: Add results to PR
    if: ${{ always() }}
    run: |
      .github/logToCs.py pre-commit.log | cs2pr

Tips

PHP Codesniffer (AKA php-cs, phpcs)

Use --report=emacs (when running with pre-commit).

Edit files that have notices from the CLI.

When running a command on the CLI, it may be helpful to edit only files with errors.

For instance, codespell reports:

codespell
./ChangeLog:8244: abadword ==> agoodword

And you want to edit the ChangeLog to make the correction.

With the bash function below it is possible to edit the reported files using viErrors codespell.

logToCs.py must be in your path.

Add to .bashrc:

viErrors() { "$EDITOR" $("$@" |& logToCs.py --name-only) ; }
_viErrors_completion() { COMPREPLY=($(compgen -c -- "${COMP_WORDS[COMP_CWORD]}")); return 0; }
complete -o default -F _viErrors_completion viErrors

or, add in completions directory

Execute the following once and everything code will be loaded when you type viErrors....<TAB>

_cdir=${BASH_COMPLETION_USER_DIR:-${XDG_DATA_HOME:-$HOME/.local/share}/bash-completion}/completions
mkdir -p "${_cdir}"
cat > "${_cdir}/viErrors.bash" << 'EOF'
viErrors() { "$EDITOR" $("$@" |& logToCs.py --name-only) ; }
_viErrors_completion() { COMPREPLY=($(compgen -c -- "${COMP_WORDS[COMP_CWORD]}")); return 0; }
complete -o default -F _viErrors_completion viErrors
EOF

Extending

In the script, patterns can be added to "PATTERNS" to match more messages.

To allow multiline patterns, the python module 'regex' is required.
