Warnings when generating `CHANGELOG.md`

[gian1200]

Describe the bug

2 warnings:

• When running commit-and-tag-version on Windows (and having default git configuration), file is generated with LF instead of CRLF.
• According to markdownlint, generated CHANGELOG.md has an extra (unnecessary) break line. One line before each commit type header is enough. No need to put 2.

Current behavior

npx commit-and-tag-version --first-release
× skip version bump on first release
√ outputting changes to CHANGELOG.md
√ committing CHANGELOG.md
warning: in the working copy of 'CHANGELOG.md', LF will be replaced by CRLF the next time Git touches it

...

Expected behavior
No warnings

Environment

• commit-and-tag-version version(s): v12.5.0
• Node/npm version: Node 20.17.0/npm 10.8.2
• OS: Windows 11

Possible Solution

• Read git configuration (git config --get core.autocrlf) and generate the file accordingly

  • if OS == Windows and core.autocrlf is true, then CRLF, else LF
  • Or just use os.EOL from os module (https://stackoverflow.com/a/16829025/767160)

• Remove the extra line from generated file

Additional context

Update:

After reading the code, it sems that both issues come from conventional-changelog.
Also, at least one is already fixed on conventional-changelog-conventionalcommits v8.0.0

• avoid double empty lines in mainTemplate conventional-changelog/conventional-changelog#1188

Currently commit-and-tag-version references an old version

That's right! The linked issue is the right place to report this. I'll leave this issue open, pending their fix (since it will mean we'll need to bump the version here).

On the fixed half of this issue - I'm definitely keen to get in the newer versions of the conventional-changelog libs - I haven't yet because it'll require a close read of the breaking changes. I'm happy to merge it in and release a breaking bump here, but I want to make sure our changelog is right.

I'm not sure how much work it'll be - it's possible that the very latest will mean we'll need a conversion to ESM (which is worth doing anyway).

[TimothyJones]

If anyone has the capacity to look at migrating to the later versions, I'd very happily accept PRs. Otherwise I'll get to it when I can.

[gian1200]

I might be able to do it in the next few days/weeks. I also notice that there are other dependencies that need some love, too (e.g. ESLint).

My only question would be regarding contribution guidelines (I didn't see any CONTRIBUTING.md). For instance:

• to not include package.lock.json (for security reasons), and only put package.json in PRs; being the responsibility of maintainers to complete the final step (run npm install)
• to not mix multiple changes on a single PR
• etc.

[TimothyJones]

Huh, I thought we had one, but it seems not.

I agree with both of those. Generally it's also:

• If adding / changing a feature please ensure there are tests for the new behaviour
• If there are user facing changes / new features, please ensure the readme is updated
• Please title the PR with conventional commits, as PRs are squash merged - and of course, these become the changelog, so it's best for fix / feat commits to be titled assuming they're read by users

[gian1200]

I tried to upgrade it, but the ESM migration is required on latest versions of conventional-changelog packages.

I also tried to upgrade them to latest version compatible with CommonJS. However, I found some issues with presets while running tests. I wasn't able to find a fix, so I took the opportunity to work on the following:

• chore: add CONTRIBUTING.md #198
• chore(deps): update dependencies (minor versions) #199
• chore(deps): upgrade ESLint to v9 #200

These should:

• ease migration to ESM
• get feedback regarding PRs on the repo

UPDATE

Preset issues are due to conventional-changelog/conventional-changelog#1308

So the only way to upgrade conventional-changelog is to move to ESM or wait for the fix
