unclog

Unclog your changelog

Build your changelog from a structured collection of independent files in your project's .changelog folder. This helps avoid annoying merge conflicts when working on multiple PRs simultaneously.

It's assumed your changelog will be output in Markdown format.

Requirements

Rust v1.52.1+ with cargo

Installation

# Install to ~/.cargo/bin/
cargo install unclog

Or you can build from source:

git clone https://github.com/informalsystems/unclog
cd unclog

# Install to ~/.cargo/bin/
cargo install --path .

Usage

Example `.changelog` folder

An example layout for a project's .changelog folder is as follows:

.changelog/                   - The project's .changelog folder, in the root of the repo.
|__ unreleased/               - Changes to be released in the next version.
|   |__ breaking-changes/     - "BREAKING CHANGES" section entries.
|   |   |__ 890-block.md      - An entry in the "BREAKING CHANGES" section.
|   |
|   |__ bug-fixes/            - "BUG FIXES" section entries.
|   |   |__ module1/          - "BUG FIXES" section entries specific to "module1".
|   |       |__ 745-rename.md - An entry in the "BUG FIXES" section under "module1".
|   |__ features/             - "FEATURES" section entries.
|   |
|   |__ summary.md            - A summary of the next release.
|
|__ v0.1.0/                   - Changes released historically in v0.1.0.
|   |__ breaking-changes/     - "BREAKING CHANGES" section entries for v0.1.0.
|   |   |__ 467-api.md        - An entry in the "BREAKING CHANGES" section for v0.1.0.
|   |   |__ 479-rpc.md        - Another entry in the "BREAKING CHANGES" section for v0.1.0.
|   |
|   |__ bug-fixes/            - "BUG FIXES" section entries for v0.1.0.
|   |
|   |__ summary.md            - A summary of release v0.1.0.
|
|__ epilogue.md               - Any content to be added to the end of the generated CHANGELOG.

For a more detailed example, see the tests/full folder for the primary integration test that uses the most features/functionality. The file tests/full/expected.md is the expected output when building the files in tests/full.

CLI

Initializing a changelog

# Creates a ".changelog" folder in the current directory.
unclog init

# Creates a ".changelog" folder in the current directory, and also copies your
# existing CHANGELOG.md into it as an epilogue (to be appended at the end of
# the final changelog built by unclog).
unclog init -e CHANGELOG.md

Adding a new unreleased entry

# First ensure that your $EDITOR environment variable is configured, or you can
# manually specify an editor binary path via the --editor flag.
#
# This will launch your configured editor and, if you add any content to the
# feature file it will be added to
# ".changelog/unreleased/features/23-some-new-feature.md".
#
# The convention is that you *must* prepend the issue/PR number to which the
# change refers to the entry ID (i.e. 23-some-new-feature relates to issue 23).
unclog add features 23-some-new-feature

# Add another feature in a different section
unclog add breaking-changes 24-break-the-api

Building a changelog

# Run from your project's directory to build your '.changelog' folder.
# Builds your CHANGELOG.md and writes it to stdout.
unclog build

# Only render unreleased changes (returns an error if none)
unclog build --unreleased

# Save the output as your new CHANGELOG.md file.
# NOTE: All logging output goes to stderr.
unclog build > CHANGELOG.md

# Increase output logging verbosity on stderr and build your `.changelog`
# folder.
unclog -v build

# Get help
unclog --help

Releasing a new version's change set

# Moves all entries in your ".changelog/unreleased" folder to
# ".changelog/v0.2.0" and ensures the ".changelog/unreleased" folder is empty.
unclog release v0.2.0

As a Library

By default, the cli feature is enabled, which builds the CLI. To use unclog as a library instead without the CLI:

[dependencies]
unclog = { version = "0.2", default-features = false }
