While [Poetry](https://python-poetry.org) finally brings us a sane solution for publishing and maintaining Python packages, many developers crave for a more _enhanced_ and safer user experience. Publicator aims to offer a convenient method for publishing your everyday libraries.

Publicator has been inspired by Sindre Sorhus' excellent [`np`](https://github.com/sindresorhus/np) package for Node.js ecosystem and graciously funded by [**Futurice Spice Program**](https://spiceprogram.org).

## Features

* Ensures you are publishing from your release branch (`main` and `master` by default)
* Ensures the working directory is clean and latest changes are pulled
* Reinstalls dependencies to ensure your project works with the latest dependency tree
* Ensures your Python version is supported by the project and its dependencies
* Runs the tests with custom test script
* Bumps the version in `pyproject.toml` and creates a Git tag based on it
* Publishes the new version to [Python Package Index](https://pypi.org) or custom repository
* Pushes commits and tags (newly & previously created) to your Git server
* If the project is hosted on GitHub opens a prefilled GitHub Releases draft after publishing
* Fully configurable via command-line arguments or the `pyproject.toml` file
* See what will be executed with preview mode, without pushing or publishing anything remotely

## Prerequisites

* **Python 3.8** or later
* **Poetry 1.1** or later
* **Git 2.11** or later

## Install

Install or run directly using `pipx`, which manages an isolated virtual environment for you.

```sh
pipx install publicator
pipx run publicator <version>
```

Alternatively, add it as dependency to your Poetry project.

```sh
poetry add --dev publicator
poetry run publicator <version>
```

## Usage

Publicator takes one command-line argument indicating the suitable version bump. It follows semantic versioning rules accurately.

```sh
# Release a new patch version (e.g. 1.0.0 -> 1.0.1)
publicator patch

# Release a new minor version (e.g. 1.0.1 -> 1.1.0)
publicator minor

# Release a new major version (e.g. 1.1.0 -> 2.0.0)
publicator major
```

Run `publicator --help` to see the full list of supported options:

```plain
$ publicator --help

  --help                          Show this message and exit.
```

### Configuration

Publicator follows the pleasantly Pythonic way of specifying the configuration within `pyproject.toml` file. Below are the default configuration values.

```toml
[tool.publicator]
any-branch    = false
clean         = true
publish       = true
push          = true
release-draft = true
tag           = true
template      = "release: %s"
```

Values passed as command-line arguments take precedence over configuration file values.

Configuration enables for more granular usage. For example, in CI/CD pipelines you might want to disable publishing the package to registry or disable creating Git tags depending on your use case.

### Preview Mode (Dry-Run)

If you'd rather skip on everything and check what would be executed, you can activate a preview mode via environment variable like so:

```sh
PUBLICATOR_PREVIEW=true publicator <version>
```

### Shell Completion

Publicator stands on the shoulders of [Typer](https://typer.tiangolo.com), which is a robust CLI library for Python. You can generate <kbd>TAB</kbd> completions for common shells such as Bash, ZSH, Fish, and Powershell.

```sh
publicator --install-completion <shell>
```
