/**
|
|
* Script for use when compiling a changelog. It will find all GH mentions in commit
|
|
* messages newer than the HEAD of the passed git tag. If no tag is passed, it will
|
|
* default to the highest versioned tag, as defined by gits `--sort=version:refname`.
|
|
*
|
|
* @param (optional) git tag of the earliest commit through which to search. If null,
|
|
* this will default to the tag on origin with the highest version name.
|
|
*
|
|
* To run this script:
|
|
* - Update local master
|
|
* - From project root, run `kotlinc -script automation/releasetools/PrintMentionedIssuesAndPrs.kts`
|
|
*
|
|
* TODO
|
|
* - Use origin/master, instead of local master
|
|
* - Interface with the GitHub API to filter out references to PRs
|
|
* - Pull down issue names for each, to make constructing the changelog easier
