changetool

A tool for working with projects that use the conventional commits.

Generates changelogs and calculates semantic versions from tags and commit messages.

Quickstart

Create a changelog since the last version tag:

changetool changelog

Create a changelog since a specific version tag:

changetool changelog --since-tag v1.0

Find the next semantic version, based on changelog:

changetool semver

Update a file with the version:

changetool semver --replace-in version.go

Tag the project wth the calculated semantic version number

changetool semver --allow-untracked --tag

Status

Becoming useful.

This tool should be able to generate useful changelogs/release notes and do intelligent semantic version calculations.

It still needs some work to be a low friction, very useful tool. Suggestions on how to make it such are welcome.

Overview

This is a first, very simple, pass at a tool for working with conventional commits projects.

The other tools that I've found are unsatisfactory in some way, either by having way too many dependencies (I'm looking at you, Node based tools) or by producing output that I don't really want, or by requiring templates and config in the project.

Changelog generation

Usage: changetool changelog

calculate changelogs

Flags:
  -h, --help    Show context-sensitive help.

info
  -d, --debug                Show debugging information
  -l, --log-format="auto"    How to show program output (auto|terminal|jsonl)
  -q, --quiet                Be less verbose than usual

locations
  -p, --path="."      Path for the git worktree/repo to log
  -o, --output="-"    File to which to send output

source
  -n, --max-commits=1000    max number of commits to check
  -s, --since-tag=STRING    Tag from which to start
  -a, --all-commits         report changelog on all commits up to --max-commits. Otherwise, report only to last version tag

calculation
  --default-type="fix"                if type is not specified in commit, assume this type
  --[no-]guess-missing-commit-type    If commit type is missing, take a guess about which it is
  --order=feat,fix,test,docs,build,refactor,chore,...
                                      order in which to list commit message types

Semantic Versioning

Usage: changetool semver --from-file=STRING

Manipulate Semantic Versions

Flags:
  -h, --help    Show context-sensitive help.

info
  -d, --debug                Show debugging information
  -l, --log-format="auto"    How to show program output (auto|terminal|jsonl)
  -q, --quiet                Be less verbose than usual

locations
  -p, --path="."               Path for the git worktree/repo to log
  -o, --output="-"             File to which to send output

      --replace-in=FILE,...    Replace version in these files
  -t, --tag                    run 'git tag' with the calculated semver

source
  -n, --max-commits=1000    max number of commits to check
  -s, --since-tag=STRING    Tag from which to start
  -a, --all-commits         report changelog on all commits up to --max-commits. Otherwise, report only to last version tag
      --from-file=STRING    Set previous revision from the first semver looking string found in this file

calculation
  --default-type="fix"                if type is not specified in commit, assume this type
  --[no-]guess-missing-commit-type    If commit type is missing, take a guess about which it is
  --order=feat,fix,test,docs,build,refactor,chore,...
                                      order in which to list commit message types
  --allow-untracked                   allow untracked files to count as clean
