From e90191de4ccd38ea163f999671f34cf492339e57 Mon Sep 17 00:00:00 2001 From: Lukasz Raczylo Date: Fri, 25 Sep 2026 19:35:48 +0100 Subject: [PATCH] feat(matching): add an opt-in regex keyword matching mode Fuzzy matching compares each keyword with every word of the commit message. A word matches if it contains the keyword's letters in order. Thus "feat" matches "fix(delegation):" and "major" matches "deps(majors):", which gives false minor and major versions. The new top-level config key "matching" accepts "fuzzy" (the default) or "regex". In regex mode every wording keyword is a Go regular expression. The tool compiles all of them when it loads the config and runs them against the full commit message, so "(?m)^" anchors a pattern to the start of a line. An invalid value, an invalid pattern, or any other config parse error in regex mode stops the tool with a non-zero exit code. It never falls back to fuzzy matching. Fuzzy mode does not change. The blacklist check moves into one helper that both modes use. A replay of 15 repositories gives the same versions as before. This change improves version precision for the repositories that opt in.

Allowed values are `fuzzy` (the default, also used when the key is absent) and `regex`. Any other value is a config error and `semver-gen` exits non-zero rather than silently falling back to `fuzzy`. + +**`fuzzy` (default):** the commit message is split on whitespace into words, and a keyword matches as soon as one word contains the keyword's letters *in order*, case-insensitive — it does not need to be a whole word or an exact substring. This is convenient but has a real false-positive risk: keyword `feat` also matches the word `fix(delegation):` (f-e-a-t appear in order inside "fix(delegation):"), and keyword `major` matches `deps(majors):`. Short, generic keywords are the most likely to over-match; test your wording list against real commit messages before relying on it. + +**`regex`:** every keyword in `wording.patch` / `wording.minor` / `wording.major` / `wording.release` is a Go RE2 regular expression (the standard library `regexp` package). Patterns are compiled once when the config is loaded — an invalid pattern makes `semver-gen` exit non-zero immediately, naming the wording list and the keyword. Each pattern is matched with `MatchString` against the **full raw commit message** (subject and body, with the original newlines, not the whitespace-split words `fuzzy` uses), so `(?m)^feat(\([^)]*\))?!?:` anchors to the start of a line. Matching is case-sensitive unless the pattern itself uses `(?i)`. The blacklist works exactly the same way in both modes. + +Regex patterns must be quoted in YAML (for example `'(?m)^fix:'`), since unquoted `^`, `:` and other YAML-significant characters can break the file's syntax; a YAML syntax error makes the tool fall back to its defaults, the same as it already does for any unreadable config file. + +```yaml +matching: regex +wording: + patch: + - '^fix(\([^)]*\))?:' + minor: + - '(?m)^feat(\([^)]*\))?!?:' + major: + # a trailer line anywhere in the commit body, e.g. "Semver-Major: dropped the v1 API" + - '(?mi)^semver-major:' +``` + +With this config, a subject line of `fix: correct off-by-one` bumps patch, `feat: add widget` bumps minor, and a body trailer of `Semver-Major: ...` bumps major regardless of case. `fix(delegation): route around dead worker` bumps patch too — the patch pattern's `(\([^)]*\))?` group allows an optional scope — but it does NOT bump minor, unlike `fuzzy` mode, where keyword `feat` matches it (see above). + #### Example configuration ```yaml @@ -276,11 +301,12 @@ wording: * `force.commit`: allows you to set commit hash from which the calculations should start * `blacklist`: terms to ignore when processing commits.
