A git commit message highlighter being nicer than the built-in one.

Help for writing good Git commit messages:

• Highlight file names and what's happening to them
• Quick Fixes for certain diagnostics
• Inform about git commit -v if it isn't being used
• git commit -v diff highlighting even when running git in not-English.
• Diagnostics for:
  • > 50 characters subject lines
  • > 72 characters subject lines
  • Not-capitalized subject lines (with Quick Fix)
  • Trailing punctuation in the subject line (with Quick Fix)
  • Code completion for JIRA issue IDs based on branch name
  • Not-capitalized JIRA issue IDs (with Quick Fix)
  • JIRA issue ID conflicting with branch name (with Quick Fix)
  • Non-blank second lines

• Comes with tests using https://github.com/PanAeon/vscode-tmgrammar-test
• Comes with unit tests for the diagnostics

• Test doing git commit in a jira-123 branch, then type "j" as the first letter. Verify that we get a suggestion. I have a feeling completion doesn't activate properly.
• Add a Quick fix for switching between [] and : style JIRA issue ID prefixes
• Highlight current branch name in the Git metadata
• Validate code formatting in CI and fail on violations
• Fail CI on linter warnings
• Move all tests under the same top subdirectory

To run the unit tests:

npm install && npm test

To install into VSCode:

1. npm run package
2. In VSCode:
   • Click Extensions
   • Click the ... menu in the top right corner
   • Click Install from VSIX...
   • Pick the 99.99.99 one, that's the perpetual development version

To check highlighting in VSCode: "Developer: Inspect Editor Tokens and Scopes"

To publish a new version:

npm run publish
