## Why

While there are other tool out there that will create a changelog output as part
of their workflow none of the ones I could find did so in a way that allowed
formatting the output via multiple templates.

The need to multiple output formats was being driven by the desire to add
changelog support to https://github.com/goreleaser/nfpm and the deb and rpm
changelog formats not being the same.

## Goals

- [x] be simple to use
- [x] provide decent default templates for deb, rpm, release and repository
      style changelog formats
- [x] be distributed as a single binary
- [x] reproducible results
  - [x] depend on the fewer external things as possible
  - [x] store changelog in a transportable format (.yml)
- [x] be possible to use it as a lib in other go projects (namely
      [goreleaser](https://goreleaser.com) itself)

## Install

```bash
go get github.com/goreleaser/chglog/cmd/chglog@latest
```

## Usage

The first steps are to run `chglog config` to initialize a configuration file
(`.chglog.yml`) and edit the generated file according to your needs:

```yaml
conventional-commits: false
deb:
  distribution: []
  urgency: ""
debug: false
owner: ""
package-name: ""
```

The next step is to run `chglog init`.

```yaml
- semver: 0.0.1
  date: 2019-10-18T16:05:33-07:00
  packager: dj gilcrease <example@example.com>
  changes:
    - commit: 2c499787328348f09ae1e8f03757c6483b9a938a
      note: |-
        oops i forgot to use Conventional Commits style message

        This should NOT break anything even if I am asking to build the changelog using Conventional Commits style message
    - commit: 3ec1e9a60d07cc060cee727c97ffc8aac5713943
      note: |-
        feat: added file two feature

        BREAKING CHANGE: this is a backwards incompatible change
    - commit: 2cc00abc77d401a541d18c26e5c7fbef1effd3ed
      note: |-
        feat: added the fileone feature

        * This is a test repo
        * so ya!
```

Then to generate a `CHANGELOG.md` file you would do `chglog format --template
repo > CHANGELOG.md`

Now whenever you go to do another release you would do `chglog add --version
v#.#.#` (version MUST be semver format)

And that's it!

## Usage as lib

You can look at the code of chglog itself to see how to use it as a library
