hardlounge/scripts/changelog.js

/*
This (very The Lounge-custom) script is a helper to generate changelog entries.

Note that it is not meant to produce fully-automated changelogs like other tools
do, but merely prepare a changelog entry without risks of mistyping a URL or
missing a contribution: changelogs are meant for humans, and therefore must be
manually curated as such, with ❤️.

## Set up:

- Create a personal access token with `public_repo` at
  https://github.com/settings/tokens. Make sure to write it down as you will not
  be able to display it again.

- Use Node.js v8+:

  ```sh
  nvm install 8
  ```

## Usage

npm v5 removes packages not listed in package.json when running `npm install` so
it is very likely you will have to run all those each time:

```sh
 export CHANGELOG_TOKEN=<The personal access token created on GitHub above>
node scripts/changelog <version>
```

`<version>` must be either:

- A keyword among: major, minor, patch, prerelease, pre
- An explicit version of either format:
  - `MAJOR.MINOR.PATCH` for a stable release, for example `2.5.0`
  - `MAJOR.MINOR.PATCH-(pre|rc).N` for a pre-release, for example `2.5.0-rc.1`

## TODOs:

- Use better labels for better categorization
- Add some stats to the git commit (how many LOCs total / in this release, etc.)
- This script requires Node v8, but `npm version` currently fails with Node v8
  as we gitignore package-lock.json (how is that even a thing?!).
