sv4git

A command line tool (CLI) to validate commit messages, bump version, create tags and generate changelogs!

Release Go Reference GitHub stars GitHub release (latest by date) GitHub all releases Software License GitHub Actions Status Go Report Card Conventional Commits

Getting Started

Pre Requirements

  • Git 2.17+

Installing

  • Download the latest release and add the binary to your path.
  • Optional: Set SV4GIT_HOME to define user configs. Check the Config topic for more information.

If you want to install from source using go install, just run:

# keep in mind that with this, it will compile from source and won't show the version on cli -h.
go install github.com/bvieira/sv4git/v2/cmd/git-sv@latest

# if you want to add the version on the binary, run this command instead.
SV4GIT_VERSION=$(go list -f '{{ .Version }}' -m github.com/bvieira/sv4git/v2@latest | sed 's/v//') && go install --ldflags "-X main.Version=$SV4GIT_VERSION" github.com/bvieira/sv4git/v2/cmd/git-sv@v$SV4GIT_VERSION

Config

YAML

There are 3 config levels when using sv4git: default, user, repository. All of them are merged considering the follow priority: repository > user > default.

To see the current config, run:

git sv cfg show
Configuration Types
Default

To check the default configuration, run:

git sv cfg default
User

For user config, it is necessary to define the SV4GIT_HOME environment variable, eg.:

SV4GIT_HOME=/home/myuser/.sv4git # myuser is just an example.

And create a config.yml file inside it, eg.:

.sv4git
└── config.yml
Repository

Create a .sv4git.yml file on the root of your repository, eg.: .sv4git.yml.

Configuration format
version: "1.1" #config version

versioning: # versioning bump
    update-major: [] # Commit types used to bump major.
    update-minor: [feat] # Commit types used to bump minor.
    update-patch: [build, ci, chore, fix, perf, refactor, test] # Commit types used to bump patch.
    # When type is not present on update rules and is unknown (not mapped on commit message types);
    # if ignore-unknown=false bump patch, if ignore-unknown=true do not bump version
    ignore-unknown: false

tag:
    pattern: '%d.%d.%d' # Pattern used to create git tag.
    filter: '' # Enables you to filter for considerable tags using git pattern syntax

release-notes:
    # Deprecated!!! please use 'sections' instead!
    # Headers names for release notes markdown. To disable a section just remove the header 
    # line. It's possible to add other commit types, the release note will be created 
    # respecting the following order: feat, fix, refactor, perf, test, build, ci, chore, docs, style, breaking-change.
    headers: 
        breaking-change: Breaking Changes
        feat: Features

    prefix: ([a-z]+\/)? # Prefix used on branch name, it should be a regex group.
    suffix: (-.*)? # Suffix used on branch name, it should be a regex group.
    disable-issue: false # Set true if there is no need to recover issue id from branch name.
    skip: [master, main, developer] # List of branch names ignored on commit message validation.
    skip-detached: false # Set true if a detached branch should be ignored on commit message validation.

commit-message:
    types: [build, ci, chore, docs, feat, fix, perf, refactor, revert, style, test] # Supported commit types.
    header-selector: '' # You can put in a regex here to select only a certain part of the commit message. Please define a regex group 'header'.
    scope:
        # Define supported scopes, if blank, scope will not be validated, if not, only scope listed will be valid.
        # Don't forget to add "" on your list if you need to define scopes and keep it optional.
        values: []
    footer:
        issue: # Use "issue: {}" if you wish to disable issue footer.
            key: jira # Name used to define an issue on footer metadata.
            key-synonyms: [Jira, JIRA] # Supported variations for footer metadata.
            use-hash: false # If false, use :<space> separator. If true, use <space># separator.
            add-value-prefix: '' # Add a prefix to issue value.
    issue:
        regex: '[A-Z]+-[0-9]+' # Regex for issue id.

Templates

sv4git uses go templates to format the output for release-notes and changelog, to see how the default template is configured check template directory. On v2.7.0+, its possible to overwrite the default configuration by adding .sv4git/templates on your repository. The cli expects that at least 2 files exists on your directory: changelog-md.tpl and releasenotes-md.tpl.

.sv4git
└── templates
    ├── changelog-md.tpl
    └── releasenotes-md.tpl

Everything inside .sv4git/templates will be loaded, so it's possible to add more files to be used as needed.

Variables

To execute the template the releasenotes-md.tpl will receive a single ReleaseNote and changelog-md.tpl will receive a list of ReleaseNote as variables.

Each ReleaseNoteSection will be configured according with release-notes.section from config file. The order for each section will be maintained and the SectionType is defined according with section-type attribute as described on the table below.

section-type ReleaseNoteSection
commits ReleaseNoteCommitsSection
breaking-changes ReleaseNoteBreakingChangeSection

⚠️ currently only commits and breaking-changes are supported as section-types, using a different value for this field will make the section to be removed from the template variables.

Check below the variables available:

ReleaseNote
  Release     string // 'v' followed by version if present, if not tag will be used instead.
  Tag         string // Current tag, if available.
  Version     *Version // Version from tag or next version according with semver.
  Date        time.Time
  Sections    []ReleaseNoteSection // ReleaseNoteCommitsSection or ReleaseNoteBreakingChangeSection
  AuthorNames []string // Author names recovered from commit message (user.name from git)

Functions

Beside the go template functions, the folowing functions are availiable to use in the templates. Check formatter_functions.go to see the functions implementation.

timefmt

Usage: timefmt time "2006-01-02"

Receive a time.Time and a layout string and returns a textual representation of the time according with the layout provided. Check https://pkg.go.dev/time#Time.Format for more information.

getsection

Usage: getsection sections "Features"

Receive a list of ReleaseNoteSection and a Section name and returns a section with the provided name. If no section is found, it will return nil.

Running

Run git-sv to get the list of available parameters:

git-sv

Run as git command

If git-sv is configured on your path, you can use it like a git command:

git sv
git sv current-version
git sv next-version

Usage

Use --help or -h to get usage information, don't forget that some commands have unique options too:

# sv help
git-sv -h

# sv release-notes command help
git-sv rn -h
Available commands
Variable description has options or subcommands

validate-commit-message, vcm Use as prepare-commit-message hook to validate commit message. ✔️
help, h Shows a list of commands or help for one command.
Use range

Commands like commit-log and commit-notes has a range option. Supported range types are: tag, date and hash.

By default, it's used --date=short at git log, all dates returned from it will be in YYYY-MM-DD format.

Range tag will use git for-each-ref refs/tags to get the last tag available if start is empty, the others types won't use the existing tags. It's recommended to always use a start limit in a old repository with a lot of commits. This behavior was maintained to not break the retrocompatibility.

Range date use git log --since and --until. It's possible to use all supported formats from git log. If end is in YYYY-MM-DD format, sv will add a day on git log command to make the end date inclusive.

Range tag and hash are used on git log revision range. If end is empty, HEAD will be used instead.

# get commit log as json using a inclusive range
git-sv commit-log --range hash --start 7ea9306~1 --end c444318

# return all commits after last tag
git-sv commit-log --range tag
Use validate-commit-message as prepare-commit-msg hook

Configure your .git/hooks/prepare-commit-msg:

#!/bin/sh

COMMIT_MSG_FILE=$1
COMMIT_SOURCE=$2
SHA1=$3

git sv vcm --path "$(pwd)" --file "$COMMIT_MSG_FILE" --source "$COMMIT_SOURCE"

Tip: you can configure a directory as your global git templates using the command below:

git config --global init.templatedir '<YOUR TEMPLATE DIR>'

Check git config docs for more information!
