Copilot · 2026-02-07T20:55:33Z

Original prompt

create a GitHub action executed at each pr targeting main and printing in a comment on the pr the changelog for the last version of fast-check along with the version at the top shown within a message such as 'changelog for version xxx:'. for the extraction of the changelog makes the code as simple as scanning the changelog file line per line until finding the start of another release note. extract this script into a dedicated file that you'll store next to the action itself

+function extractLatestChangelog() {


@copilot add a parameter to this function to specify the sub-directory where to take the changelog from. It could be fast-check, but also ava or any of the others.

Added a packageDir parameter to extractLatestChangelog() — it now takes the sub-directory name (e.g. 'fast-check', 'ava', 'jest') and reads packages/<packageDir>/CHANGELOG.md. Commit: 6d902a3.

@copilot it should be reexecuted whenever the pr gets updated. Use the same trigger as other actions based on pr trigger

Updated the trigger to types: [opened, edited, reopened, synchronize] matching the pattern used by validate-pr-title.yml. Commit: 6d902a3.

@copilot use dirname instead

Switched to __dirname for path resolution: path.join(__dirname, '..', '..', '..', 'packages', packageDir, 'CHANGELOG.md'). Commit: 2078bc5.

@copilot Extract the name of the release or tag line too

Now extracting the release name (italic tag line like _Proper attestation file naming_) into a releaseName field. The return type is now {version, releaseName, changelog}. Commit: 2078bc5.

@copilot also return the tag name of such version, check how we named version in the past. fast-check does it differently from others but others use the same pattern

Added a computeTagName helper and a tag field to the return value. fast-check uses v<version>, others use <packageDir>/v<version> — matching the convention in generate-changelog.cjs. Commit: e2c8985.

+    if (foundFirst) {
+      const releaseNameMatch = line.match(/^_(.+)_$/);
+      if (releaseNameMatch && !releaseName) {


@copilot only use if(abc) or if(!abc) if abc is a boolean value, otherwise clearly specify the value you check for (null? undefined? 0? Empty string?)

Applies the guideline for the whole file

Updated all checks to use explicit comparisons: foundFirst === true, releaseNameMatch !== null, releaseName === ''. Commit: e2c8985.

@copilot change the trigger of the workflow..it should not be on pull request but manually triggered with something like:

on:
workflow_dispatch:
inputs:
package:
description: 'Package to release'
required: true
type: choice
options:
- fast-check
- ava
- jest
- vitest
- worker
- poisoning
- packaged

Instead of printing a comment, create a new release using the action we already use in another action. Make suer to mark fast-check releases as latest while for the others dont toggle on latest. Make sure you configure the action to create the tag as it will be missing when the action will run and this is the role of this action to create it

+      if (releaseNameMatch !== null && releaseName === '') {
+        releaseName = releaseNameMatch[1];
+      }
+      changelogLines.push(line);


@copilot put it in a else so that we don't put the release name in the changelog

Moved changelogLines.push(line) into an else branch so the release name line is excluded from the changelog body. Commit: 4267afc.

+            core.setOutput('release_name', releaseName);
+            core.setOutput('changelog', changelog);
+      - name: Create GitHub Release


@copilot add a dry run boolean value that could be checked to avoid running the creation of the release

Added a dry_run boolean input (default: false). When set to true, the release creation step is skipped via an if condition, while the changelog extraction still runs so you can verify the outputs. Commit: 224151d.

@copilot in dry run print the values you extracted via the script in the condole (maybe always print them)

Added console.log calls that always print the extracted version, tag, release name, and changelog — visible in both normal and dry run mode. Commit: fad6e32.
