got an assertion error on `chan removed 'whatever'`

[slashformotion]

[Unreleased]: https://github.com/slashformotion/hugo-tufte/compare/v0.2.0...HEAD
[0.1.2]: https://github.com/slashformotion/hugo-tufte/releases/tag/v0.2.0
[0.1.2]: https://github.com/slashformotion/hugo-tufte/releases/tag/v0.1.2

[0.1.0]: https://github.com/slashformotion/hugo-tufte/releases/tag/v0.1.0

looks like it comes from here:

chan/packages/chast/src/index.js

Line 27 in 4071fe4

assert(identifier, 'The `identifier` of the release is required.')

I tried to understand what is going on but I don't know javascript, so...yeah..i'm stuck on this one

Hi @slashformotion sorry for the delay.

Could you run the commands with the --verbose option to see if there is any additional info. Thanks.

I do have the same error message when running chan added text:

> chan added text --verbose
[chan] [added] › ✖  error     AssertionError [ERR_ASSERTION]: The `identifier` of the release is required.

I did run a bit through the parseHeadingRelease function. My heading is this:

{
  type: 'heading',
  depth: 2,
  children: [ { type: 'text', value: '[1.8.2] - 2021-12-03' } ]
}

This results in link being null, and text ending up as { type: 'text', value: '[1.8.2] - 2021-12-03' }. This means we end up in here:

chan/packages/remark-chan/src/index.js

Lines 73 to 96 in a1e1fac

	} else {
	const match = text.value.match(/\[(.*?)\]/)
	if (match) {
	const tag = match[1]
	if (tag === 'Unreleased') {
	identifier = 'unreleased'
	version = tag
	unreleased = true
	}
	if (tag === 'YANKED') {
	const [first, rest] = text.value.trim().split(' - ')
	const [second] = rest.split(' ')
	identifier = first
	version = identifier
	date = second
	yanked = true
	}
	} else {
	// first release: 0.0.1 - 2014-05-31
	([version, date] = text.value.trim().split(' - '))
	identifier = version
	}
	}

The pattern does match, but the block only handle Unreleased and yanked tags. 1.8.2 is ignored. This results in identifier, version, date, url all being undefined when returned:

{
  identifier: undefined,
  version: undefined,
  url: undefined,
  date: undefined,
  unreleased: false,
  yanked: false
}

This then triggers the assertion in createRelease.

In my case, two link reference were missing at the bottom (1.8.1 and 1.8.2):

[Unreleased]: .../compare/v1.8.0...HEAD
[1.8.0]: .../compare/v1.7.0...v1.8.0

Adding them fixed the error. The sample above seems to miss the reference for 0.2.0.

I would appreciate it if chan could fix that automatically, if that is possible. It is a really nice tool I use fairly regularly. Thanks a lot!
