Build Status

A conventional changelog for the rest of us

About

clog creates a changelog automatically from your local git metadata. See the clogs changelog.md for an example.

The way this works, is every time you make a commit, you ensure your commit subject line follows the conventional format. Then when you wish to update your changelog, you simply run clog inside your local repository with any options you'd like to specify.

NOTE: clog also supports empty components by making commit messages such as alias: message or alias(): message (i.e. without the component)

Usage

There are two ways to use clog, as a binary via the command line or as a library in your applications via clog-lib.

Binary (Command Line)

In order to use clog via the command line you must first obtain a binary by either compiling it yourself, or downloading and installing one of the precompiled binaries.

cargo install

If you want to both compile and install clog using cargo you can simply run

cargo install clog-cli

Compiling

Follow these instructions to compile clog, then skip down to Installation.

  1. Ensure you have current version of cargo and Rust installed
  2. Clone the project $ git clone https://github.com/clog-tool/clog-cli && cd clog-cli
  3. Build the project $ cargo build --release
  4. Once complete, the binary will be located at target/release/clog

Using a Precompiled Binary

Currently there are no precompiled binaries available.

Note: The Mac distribution is available on npm via clog-cli.

Installation

Once you have downloaded, or compiled, clog you simply need to place the binary somewhere in your $PATH. If you are not familiar with $PATH read-on; otherwise skip down to Using clog.

Arch Linux

You can use clog-bin from the AUR, or follow the instructions for Linux / OS X

Linux / OS X

You have two options, place clog into a directory that is already located in your $PATH variable (To see which directories those are, open a terminal and type echo "${PATH//:/\n}", the quotation marks are important), or you can add a custom directory to your $PATH

Option 1 If you have write permission to a directory listed in your $PATH or you have root permission (or via sudo), simply copy the clog to that directory # sudo cp clog /usr/local/bin

Option 2 If you do not have root, sudo, or write permission to any directory already in $PATH you can create a directory inside your home directory, and add that. Many people use $HOME/.bin to keep it hidden (and not clutter your home directory), or $HOME/bin if you want it to be always visible. Here is an example to make the directory, add it to $PATH, and copy clog there.

Simply change bin to whatever you'd like to name the directory, and .bashrc to whatever your shell startup file is (usually .bashrc, .bash_profile, or .zshrc)

$ mkdir ~/bin
$ echo "export PATH=$PATH:$HOME/bin" >> ~/.bashrc
$ cp clog ~/bin
$ source ~/.bashrc
Windows

On Windows 7/8 you can add directory to the PATH variable by opening a command line as an administrator and running

C:\> setx path "%path%;C:\path\to\clog\binary"

Otherwise, ensure you have the clog binary in the directory which you operating in the command line from, because Windows automatically adds your current directory to PATH (i.e. if you open a command line to C:\my_project\ to use clog ensure clog.exe is inside that directory as well).

Using clog from the Command Line

clog works by reading your git metadata and specially crafted commit messages and subjects to create a changelog. clog has the following options available.

Usage: clog [OPTIONS]

Options:
  -r, --repository <URL>  Repository used for generating commit and issue links (without the .git, e.g.
                          https://github.com/thoughtram/clog)
  -f, --from <COMMIT>     e.g. 12a8546
  -T, --format <STR>      The output format, defaults to markdown [default: markdown] [possible values: markdown,
                          json]
  -M, --major             Increment major version by one (Sets minor and patch to 0)
  -g, --git-dir <PATH>    Local .git directory (defaults to "$(pwd)/.git")
  -w, --work-tree <PATH>  Local working tree of the git project (defaults to "$(pwd)")
  -m, --minor             Increment minor version by one (Sets patch to 0)
  -p, --patch             Increment patch version by one
  -s, --subtitle <STR>    
  -t, --to <COMMIT>       e.g. 8057684 [default: HEAD]
  -o, --outfile <PATH>    Where to write the changelog (Defaults to stdout when omitted)
  -c, --config <COMMIT>   The Clog Configuration TOML file to use [default: .clog.toml]
  -i, --infile <PATH>     A changelog to append to, but *NOT* write to (Useful in conjunction with --outfile)
      --setversion <VER>  e.g. 1.0.1
  -F, --from-latest-tag   use latest tag as start (instead of --from)
  -l, --link-style <STR>  The style of repository link to generate [default: github] [possible values: github,
                          gitlab, stash, cgit]
  -C, --changelog <PATH>  A previous changelog to prepend new changes to (this is like using the same file for both
                          --infile and --outfile and should not be used in conjunction with either)
  -h, --help              Print help
  -V, --version           Print version


If your .git directory is a child of your project directory (most common, such as /myproject/.git) AND not in the
current working directory (i.e you need to use --work-tree or --git-dir) you only need to specify either the
--work-tree (i.e. /myproject) OR --git-dir (i.e. /myproject/.git), you don't need to use both.

If using the --config to specify a clog configuration TOML file NOT in the current working directory (meaning you
need to use --work-tree or --git-dir) AND the TOML file is inside your project directory (i.e.
/myproject/.clog.toml) you do not need to use --work-tree or --git-dir.

Try it!

In order to see it in action, you'll need a repository that already has some of those specially crafted commit messages in it's history. For this, we'll use the clog repository itself.

  1. Clone the repo git clone https://github.com/clog-tool/clog-cli && cd clog-cli

  2. Ensure you already clog binary from any of the steps above

  3. There are many, many ways to run clog. Note, in these examples we will be typing the same options over and over again, in times like that we could a clog TOML configuration file to specify those options that don't normally change. Also note, all these CLI options have short versions as well, we're using the long version because they're easier to understand.

  4. Let's start by picking up only new commits since our last release (this may not be a lot...or none)

  5. Run clog -r https://github.com/clog-tool/clog-cli --outfile only_new.md

  6. By default, clog outputs to stdout unless you have a file set inside a TOML configuration file. (Note, we could have used the shell > operator instead of --outfile)

  7. Anything options you set via the CLI will override anything you set the configuration file.

  8. Let's now tell clog where it can find our old changelog, and prepend any new commits to that old data

  9. Run clog -r https://github.com/clog-tool/clog-cli --infile changelog.md --outfile new_combined.md

  10. Finally, let's assume like most projects we just want to use one file, and prepend all new data to our old changelog (most useful)

  11. First make a backup of the changelog.md so you can compare it later cp changelog.md changelog.md.bak

  12. Run clog -r https://github.com/clog-tool/clog-cli --changelog changelog.md

  13. Try viewing any of the only_new.md, new_combined.md, changelog.md.bak, or changelog.md in your favorite markdown viewer to compare them.

As a Library

See the documentation or clog-lib for information on using clog in your applications. You can also see the clog crates.io page.

Default Options

clog can also be configured using a default configuration file so that you don't have to specify all the options each time you want to update your changelog. To do this add a .clog.toml file to your repository.

[clog]
# A repository link with the trailing '.git' which will be used to generate
# all commit and issue links
repository = "https://github.com/clog-tool/clog-cli"
# A constant release title
subtitle = "my awesome title"

# specify the style of commit links to generate, defaults to "github" if omitted
link-style = "github"

# The preferred way to set a constant changelog. This file will be read for old changelog
# data, then prepended to for new changelog data. It's the equivalent to setting
# both infile and outfile to the same file.
#
# Do not use with outfile or infile fields!
#
# Defaults to stdout when omitted
changelog = "mychangelog.md"

# This sets an output file only! If it exists already, new changelog data will be
# prepended, if not it will be created.
#
# This is useful in conjunction with the infile field if you have a separate file
# that you would like to append after newly created clog data
#
# Defaults to stdout when omitted
outfile = "MyChangelog.md"

# This sets the input file old! Any data inside this file will be appended to any
# new data that clog picks up
#
# This is useful in conjunction with the outfile field where you may wish to read
# from one file and append that data to the clog output in another
infile = "My_old_changelog.md"

# This sets the output format. There are two options "json" or "markdown" and
# defaults to "markdown" when omitted
output-format = "json"

# If you use tags, you can set the following if you wish to only pick
# up changes since your latest tag
from-latest-tag = true

Now you can update your MyChangelog.md with clog --patch (assuming you want to update from the latest tag version, and increment your patch version by 1).

Note: Any options you specify at the command line will override options set in your .clog.toml

Custom Sections

By default, clog will display three sections in your changelog, Features, Performance, and Bug Fixes. You can add additional sections by using a .clog.toml file. To add more sections, simply add a [sections] table, along with the section name and aliases you'd like to use in your commit messages:

[sections]
MySection = ["mysec", "ms"]

Now if you make a commit message such as mysec(Component): some message or ms(Component): some message there will be a new "MySection" section along side the "Features" and "Bug Fixes" areas.

NOTE: Sections with spaces are supported, such as "My Special Section" = ["ms", "mysec"]
