CHANGELOG generator implemented in Go (Golang).
Anytime, anywhere, Write your CHANGELOG.
- git-chglog
- โป๏ธ High portability
- It works with single binary. Therefore, any project (environment) can be used.
- ๐ฐ Simple usability
- The CLI usage is very simple and has low learning costs.
- For example, the simplest command is
$ git-chglog
.
- ๐ High flexibility
- Commit message format and ...
- CHANGELOG's style (Template) and ...
- etc ...
git-chglog
internally uses the git
command to get data to include in the CHANGELOG.
The basic steps are as follows.
- Get all the tags.
- Get the commits contained between
tagA
andtagB
. - Execute with all tags corresponding to tag query that were specified in Step 1 and 2.
We will start with installation and introduce the steps up to the automatic generation of the configuration file and template.
Please install git-chglog
in a way that matches your environment.
Homebrew (for macOS users)
$ brew tap git-chglog/git-chglog
$ brew install git-chglog
Scoop (for Windows users)
$ scoop install git-chglog
$ asdf plugin-add git-chglog https://github.com/GoodwayGroup/asdf-git-chglog.git
$ asdf install git-chglog latest
$ go get -u github.com/git-chglog/git-chglog/cmd/git-chglog
If you are using another platform, you can download a binary from the releases page and place it in a directory in your $PATH
.
You can check with the following command whether the git-chglog
command was included in a directory that is in your $PATH
.
$ git-chglog --version
# outputs the git-chglog version
git-chglog
requires configuration files and templates to generate a CHANGELOG.
However, it is a waste of time to create configuration files and templates from scratch.
Therefore we recommend using the --init
option which will create them interactively ๐
$ git-chglog --init
You are now ready for configuration files and templates!
Let's immediately generate a CHANGELOG of your project.
By doing the following simple command, Markdown for your CHANGELOG is displayed on stdout.
$ git-chglog
Use -o
(--output
) option if you want to output to a file instead of stdout.
$ git-chglog -o CHANGELOG.md
You now know basic usage of git-chglog
!
In order to make a better CHANGELOG, please refer to the following document and customize it.
$ git-chglog --help
USAGE:
git-chglog [options] <tag query>
There are the following specification methods for <tag query>.
1. <old>..<new> - Commit contained in <old> tags from <new>.
2. <name>.. - Commit from the <name> to the latest tag.
3. ..<name> - Commit from the oldest tag to <name>.
4. <name> - Commit contained in <name>.
OPTIONS:
--init generate the git-chglog configuration file in interactive
--config value, -c value specifies a different configuration file to pick up (default: ".chglog/config.yml")
--output value, -o value output path and filename for the changelogs. If not specified, output to stdout
--next-tag value treat unreleased commits as specified tags (EXPERIMENTAL)
--silent disable stdout output
--no-color disable color output [$NO_COLOR]
--no-emoji disable emoji output [$NO_EMOJI]
--no-case disable case sensitive filters
--tag-filter-pattern value, -p value regular expression of tag filter. Is specified, only matched tags will be picked
--help, -h show help
--version, -v print the version
EXAMPLE:
$ git-chglog
If <tag query> is not specified, it corresponds to all tags.
This is the simplest example.
$ git-chglog 1.0.0..2.0.0
The above is a command to generate CHANGELOG including commit of 1.0.0 to 2.0.0.
$ git-chglog 1.0.0
The above is a command to generate CHANGELOG including commit of only 1.0.0.
$ git-chglog $(git describe --tags $(git rev-list --tags --max-count=1))
The above is a command to generate CHANGELOG with the commit included in the latest tag.
$ git-chglog --output CHANGELOG.md
The above is a command to output to CHANGELOG.md instead of standard output.
$ git-chglog --config custom/dir/config.yml
The above is a command that uses a configuration file placed other than ".chglog/config.yml".
You can specify which commits to include in the generation of CHANGELOG using <tag query>
.
The table below shows Query patterns and summaries, and Query examples.
Query | Description | Example |
---|---|---|
<old>..<new> |
Commit contained in <new> tags from <old> . |
$ git-chglog 1.0.0..2.0.0 |
<name>.. |
Commit from the <name> to the latest tag. |
$ git-chglog 1.0.0.. |
..<name> |
Commit from the oldest tag to <name> . |
$ git-chglog ..2.0.0 |
<name> |
Commit contained in <name> . |
$ git-chglog 1.0.0 |
The git-chglog
configuration is a yaml file. The default location is .chglog/config.yml

๐ Even with styles that are not yet supported, it is possible to make ordinary CHANGELOG.
Why do not you output files by default?
This is not for the purpose of completely automating the generation of CHANGELOG files, it is only for assisting generation.It is ideal to describe everything included in CHANGELOG in your commits. But actually it is very difficult to do it perfectly.
There are times when you need to edit the generated output to write a great CHANGELOG.
By displaying it on the standard output, it makes it easy to change the contents.
Can I commit CHANGELOG changes before creating tags?
Yes, it can be solved by using the --next-tag
flag.
For example, let's say you want to upgrade your project to 2.0.0
.
You can create CHANGELOG containing 2.0.0
as follows.
$ git-chglog --next-tag 2.0.0 -o CHANGELOG.md
$ git commit -am "release 2.0.0"
$ git tag 2.0.0
The point to notice is that before actually creating a tag with git
, it is conveying the next version with --next-tag
๐
This is a step that is necessary for project operation in many cases.
Can I generate a CHANGELOG based on certain tags?
Yes, it can be solved by use the --tag-filter-pattern
flag.
For example, the following command will only include tags starting with "v":
$ git-chglog --tag-filter-pattern '^v'
- Windows Support
- More styles (GitHub, GitLab, Bitbucket ๐)
- Snippetization of configuration files (improvement of reusability)
- More test test test ... (and example)
