Fix regex character class handling for newline/CR in minimize parser#368
Fix regex character class handling for newline/CR in minimize parser#368
Conversation
In OCaml's Str module, escape sequences like \n and \r inside character classes [...] are treated as literal 'n' and 'r' characters, not as newline and carriage return. This caused the minimize comment parsing to fail when matching against actual newlines in comment bodies. Fixed by using actual newline and carriage return characters in the character classes instead of escape sequences. Co-authored-by: JasonGross <396076+JasonGross@users.noreply.github.com>
Added test cases covering: - Basic minimize with options and code block - Minimize with no options - Minimize with preceding text - Minimize with text on same line before @coqbot - Minimize with colon after bot name - The exact failing case from the issue - CI minimize patterns Co-authored-by: JasonGross <396076+JasonGross@users.noreply.github.com>

@copilot Please ensure that the tests are run on CI (new CI workflow seems fine if the tests are not already automatically run)

Error: No rule found for bot-components/.github-token
The previous CI workflow ran `dune build` which tried to regenerate the GitHub/GitLab GraphQL schemas, requiring a GitHub token. Since the schemas are already committed to the repo via `(mode promote)`, we only need to run `dune runtest` which builds what's needed for tests without triggering schema regeneration rules.

The dune rule for github-schema.json has `(deps ../.github-token ...)` which requires the token file to exist even when using `(mode promote)` with the schema already committed.

Summary
This PR fixes a bug where the bot was not handling
@coqbot minimizecomments correctly, causing "Unhandled comment" errors.Root Cause
In OCaml's Str module, escape sequences like
\nand\rinside character classes[...]are treated as literal 'n' and 'r' characters, not as newline and carriage return. This caused the regex patterns for parsing minimize comments to fail when matching against actual newlines in comment bodies.For example, the pattern
[^\n\r]was incorrectly matching "not n, not r" instead of "not newline, not carriage return".Changes
bot-components/utils/Minimize_parser.ml: Fixed regex character classes to use actual newline and carriage return characters instead of escape sequences in:
parse_minimize_text_of_body- the main minimize comment parserparse_ci_minimize_text_of_body- the CI minimize comment parserparse_resume_ci_minimize_text_of_body- the resume CI minimize parsertests/test_minimize_parser.ml: Added regression tests covering:
.github/workflows/ci.yml: Added CI workflow to run tests on pull requests and pushes to master

Fixes #367
