distlift

distlift is a small command-line helper for people who ship software packages. If your project lives in Git and you use a version number (like 1.2.3) that you bump when you release, distlift can automate the boring steps: update the version in your project files, refresh a changelog from recent commits, create a Git commit and tag, and optionally push to your remote or build and publish installable packages.

You run it from a terminal in your project folder. It is aimed at Python and JavaScript projects out of the box; advanced users can extend it with plugins.

What you need first

• Python 3.11 or newer installed on your computer.
• Your code in a Git repository (distlift talks to Git for tags and history).
• A habit of running terminal commands from the folder that contains your project (the “repo root”).

Install

Open a terminal and run:

pip install distlift

If you use pip only for your user account, that is fine. After install, you should be able to run:

distlift --help

If that prints help text, the tool is on your path. You can also run it as python -m distlift if your Python environment prefers that style.

The simplest workflow

From your project’s root directory, with a clean saved state in Git (no half-finished edits you are not ready to commit), run:

distlift

With no extra words, distlift performs a patch release: it bumps the last part of the version (e.g. 1.0.4 → 1.0.5), updates your manifest (such as pyproject.toml or package.json), can update CHANGELOG.md when that is enabled, then commits, tags, and pushes according to your settings.

You can pass one of these on the same command instead: --major, --minor, --patch, or --version / -v with an exact version (for example distlift --minor or distlift --version 2.0.0). You cannot combine two of them on one run.

Practice run (nothing is written to Git):

distlift --dry-run

That only shows what would happen—safe when you are learning.

Skip the changelog for one run:

distlift --no-changelog

Keep the changelog but do not open an editor to tweak the new entry:

distlift --no-changelog-editor

After a successful release, build installable files locally:

distlift --build

Build and upload to a registry (only when you have publish credentials and configuration set up):

distlift --publish

More detail in the log:

distlift -V

or

distlift --verbose

Work on another folder without cd there:

distlift --repo-root "C:\path\to\your\repo"

(Use the path style your operating system expects.)

Choosing how big the version jump is

The bare distlift shortcut (see above) accepts --major, --minor, --patch, or --version / -v the same way as distlift release simple.

When you prefer the explicit subcommand, use:

distlift release simple --patch
distlift release simple --minor
distlift release simple --major
distlift release simple --version 2.0.0

You must pick exactly one of those version options for release simple. Add --dry-run anytime to rehearse.

Monorepos (several packages in one repository)

If your repository is configured for multiple packages, each with its own version and tag, use:

distlift release monorepo --all-changed

or release specific names:

distlift release monorepo --package my-lib --package my-app

You can pass --major, --minor, --patch, or --version / -v on release monorepo as well (at most one per run). If you pass none of these, --default-bump controls the bump kind (it defaults to patch).

Unified version: --version 2.0.0 sets that same next version on every package included in that release (still respecting each package’s version format). On an interactive terminal, distlift asks you to confirm before continuing. In non-interactive environments (typical CI), no prompt is shown.

Add --dry-run to preview what would happen without writing to Git.

Dependent package updates

When you release package a, distlift can update dependency declarations on other packages in the same monorepo (for example b and c that depend on a) before the release commit. If b is part of the same release, its tagged manifest will contain both b's new version and the new constraint on a.

Enable built-in scanning in distlift.toml:

[dependency_updates]
enabled = true
include_current_monorepo = true
python_version_template = ">={version}"
javascript_version_template = "^{version}"

[[dependency_updates.rules]]
package = "a"
projects = ["b", "c"]
version_template = "=={version}"

Per-package switches (monorepo only; ignored in simple mode):

[[monorepo.packages]]
name = "a"
path = "packages/a"
dependency_updates_trigger_enabled = true
dependency_updates_receive_enabled = true

Outside a release, apply the same logic manually:

distlift dependencies autoupdate --released a=1.2.0

Use --dry-run to preview changes. When updates run, the dependencies_autoupdated hook fires (configure under [hooks]). Hook subprocesses also receive:

• DISTLIFT_DEPENDENCY_UPDATE_COUNT — number of declarations changed
• DISTLIFT_DEPENDENCY_UPDATE_PROJECTS — dependent project names (sorted)
• DISTLIFT_DEPENDENCY_UPDATE_FILES — manifest paths updated (sorted)
• DISTLIFT_DEPENDENCY_UPDATE_DEPENDENCIES — dependency names changed (sorted)
• DISTLIFT_DEPENDENCY_UPDATE_TRIGGERS — released packages that triggered updates (sorted)

Custom rules in a plugin: scaffold a small pip-installable project:

distlift plugins create-dependency-updater my-updater \
  --output plugins/my-updater \
  --watch-package a \
  --project b

Install with python -m pip install -e plugins/my-updater, or load from a directory without installing:

[plugins]
directories = ["plugins/my-updater"]

Deploy marker tags (CI)

When one Git tag should trigger deployment for the whole repo (for example after several package versions were released), use:

distlift deploy

That creates the next tag deploy_1, deploy_2, … at HEAD and pushes it to each configured remote. The working tree must be clean. The prefix is configurable (default deploy): see [deploy].tag_prefix in TOML or DISTLIFT_DEPLOY_TAG_PREFIX.

Use --dry-run to print the planned tag without creating it. With deploy.verify_indexes or --verify-indexes, distlift checks that each package’s manifest version is visible on PyPI (python -m pip index …) or npm (npm view …), using your normal pip / npm configuration. See also DISTLIFT_DEPLOY_VERIFY_INDEXES.

distlift can maintain a Keep a Changelog-style CHANGELOG.md using your Git history (and conventional commit messages when enabled).

See what would be added for a version, without saving:

distlift changelog preview --version 1.2.3

Write or update the changelog file for that version:

distlift changelog update --version 1.2.3

By default this may open your text editor so you can polish the entry; add --no-editor to skip that step.

Create a starter changelog file if you do not have one:

distlift changelog init

In monorepo setups, many changelog commands accept --package <name> so the right subfolder is used.

Configuration commands

Show the settings distlift is actually using (and where each value came from):

distlift config show

Check that configuration is valid:

distlift config validate

Create or open config files for your user account or the whole machine (these create starter files or open them in your editor):

distlift config init-user
distlift config edit-user
distlift config init-system
distlift config edit-system

System-level files on Windows often live under shared “Program Data” folders and may need administrator rights to edit.

Choosing the text editor

Whenever distlift needs to open a file in an editor (when polishing a generated changelog entry, or when you run distlift config edit-user or distlift config edit-system), it looks for a command to launch in this order:

1. The GIT_EDITOR environment variable (the same one Git itself uses for commit messages).
2. The VISUAL environment variable (the POSIX convention for a full-screen editor such as vim, nano, or code --wait).
3. The EDITOR environment variable (the older POSIX fallback, e.g. notepad on Windows).
4. The editor setting from your distlift config file, or the DISTLIFT_EDITOR environment variable.

So if none of the standard editor environment variables are set on your system, you can still tell distlift which editor to use by writing one line in your user config:

editor = "code --wait"

You can place that in any distlift TOML layer (distlift.toml / .distlift.toml, [tool.distlift] inside pyproject.toml, your user config file, or the system one). The values saved by distlift config init-user already include a commented-out example.

distlift config show prints the effective editor (or (unset) when no layer provides one).

Plugins

List extensions distlift loaded (built-ins and any you configured):

distlift plugins list

Getting unstuck

Every command accepts --help, for example:

distlift changelog --help
distlift release simple --help

That lists all flags for that command. If something fails, read the message in the terminal—distlift usually explains whether the problem is configuration, Git state, or a missing file.

distlift is release automation for developers; it performs real Git operations when not in --dry-run. Always commit or stash unrelated work, read --help before unfamiliar flags, and use --dry-run until you are comfortable with the plan.
