clog

A library for generating a conventional changelog from git metadata, written in Rust

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.

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 (See clog-cli for details) or as a library in your applications.

See the documentation for information on using clog in your applications.

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 clog-lib repository (we will clone to our home directory to make things simple, feel free to change it)

$ git clone https://github.com/clog-tool/clog-lib

2. Add clog as a dependency in your Cargo.toml

[dependencies]
clog = "*"

3. Use the following in your src/main.rs

extern crate clog;

use clog::Clog;

fn main() {
    // Create the struct
    let mut clog = Clog::with_git_work_tree("~/clog")
        .unwrap()
        .repository("https://github.com/thoughtram/clog")
        .subtitle("Crazy Dog")
        .changelog("changelog.md")
        .from("6d8183f")
        .version("0.1.0");

    // Write the changelog to the current working directory
    //
    // Alternatively we could have used .write_changelog_to("/somedir/some_file.md")
    clog.write_changelog().unwrap();
}

4. Compile and run `$ cargo build --release && ./target/release/bin_name
5. View the output in your favorite markdown viewer! $ vim changelog.md

Configuration

clog can also be configured using a configuration file in TOML.

See the examples/clog.toml for available options.
