## Getting Started

### Requirements

- Git 2.17+

### Installing

- Download the latest release and add the binary to your path.
- Optional: Set `GITSV_HOME` to define user configurations. Check the [Configuration](#configuration) topic for more information.

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

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

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

### Configuration

#### YAML

There are 3 configuration levels when using git-sv: [default](#default), [user](#user), [repository](#repository). All of them are merged considering the follow priority: **repository > user > default**.

To see the current configuration, run:

```Shell
git sv cfg show
```

##### Configuration Types

###### Default

To check the default configuration, run:

```Shell
git sv cfg default
```

###### User

For user configuration, it is necessary to define the `GITSV_HOME` environment variable, e.g.:

```Shell
GITSV_HOME=/home/myuser/.gitsv # myuser is just an example.
```

And create a `config.yml` file inside it, e.g.:

```Shell
.gitsv
└── config.yml
```

###### Repository

Create a `.gitsv/config.yml` file on the root of your repository, e.g. [.gitsv/config.yml](.gitsv/config.yml).

##### Configuration format

```Yaml
version: "1.1" #configuration 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
    fix: Bug Fixes

  sections: # Array with each section of release note. Check template section for more information.
    - name: Features # Name used on section.
      section-type: commits # Type of the section, supported types: commits, breaking-changes.
      commit-types: [feat] # Commit types for commit section-type, one commit type cannot be in more than one section.
    - name: Bug Fixes
      section-type: commits
      commit-types: [fix]
    - name: Breaking Changes
      section-type: breaking-changes

branches: # Git branches config.
  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

**git-sv** uses _go templates_ to format the output for `release-notes` and `changelog`, to see how the default template is configured check [template directory](cmd/git-sv/resources/templates). It's possible to overwrite the default configuration by adding `.gitsv/templates` on your repository. The cli expects that at least 2 files exists on your directory: `changelog-md.tpl` and `releasenotes-md.tpl`.

```Shell
.gitsv
└── templates
    ├── changelog-md.tpl
    └── releasenotes-md.tpl
```

Everything inside `.gitsv/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 configuration 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 |

> :warning: 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.

### Running

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

```Shell
git-sv
```

#### Run as git command

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

```Shell
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:

```Shell
$ git-sv --help
NAME:
   git-sv - Semantic version for git.

USAGE:
   git-sv [global options] command [command options] [arguments...]

VERSION:
   20e64f8

COMMANDS:
   config, cfg                   cli configuration
   current-version, cv           get last released version from git
   next-version, nv              generate the next version based on git commit messages
   commit-log, cl                list all commit logs according to range as jsons
   commit-notes, cn              generate a commit notes according to range
   release-notes, rn             generate release notes
   changelog, cgl                generate changelog
   tag, tg                       generate tag with version based on git commit messages
   commit, cmt                   execute git commit with convetional commit message helper
   validate-commit-message, vcm  use as prepare-commit-message hook to validate and enhance commit message
   help, h                       Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --help, -h     show help
   --version, -v  print the version
```

##### 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](https://git-scm.com/docs/git-log#Documentation/git-log.txt---dateltformatgt) 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 an old repository with a lot of commits.

Range `date` use git log `--since` and `--until`. It's possible to use all supported formats from [git log](https://git-scm.com/docs/git-log#Documentation/git-log.txt---sinceltdategt). 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](https://git-scm.com/docs/git-log#Documentation/git-log.txt-ltrevisionrangegt). If `end` is empty, `HEAD` will be used instead.

```Shell
# 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
```
