# outdated

[![Build Status](https://travis-ci.org/alexmojaki/outdated.svg?branch=master)](https://travis-ci.org/alexmojaki/outdated) [![Coverage Status](https://coveralls.io/repos/github/alexmojaki/outdated/badge.svg?branch=master&uncache)](https://coveralls.io/github/alexmojaki/outdated?branch=master) [![Supports Python versions 2.7 and 3.5+](https://img.shields.io/pypi/pyversions/outdated.svg)](https://pypi.python.org/pypi/outdated)

This is a mini-library which, given a package name and a version, checks if it's the latest version available on PyPI.

To install:

    pip install outdated

## Quickstart:

    from outdated import warn_if_outdated

    warn_if_outdated('my-package-name', '1.2.3')

This will:

- Show a warning if the given version is not the latest. The warning includes the package name, the given version, and the latest version.

- Perform the check in a background thread (so it doesn't delay anything)

- Make at most one HTTP call (unless there is an HTTP error, in which case it will try 3 times) to the PyPI server for that specific package

- Cache the result of the HTTP call on disk for 24 hours

- Show a warning if any exception occurs during the check

This will *not* check what version is currently installed, it will only use the given version. Library authors must make sure that the version in their `setup.py` matches the version here.

The package name argument must be exactly the name used on PyPI, so that e.g. https://pypi.python.org/pypi/my-package-name is a valid URL.

Optional arguments:

- `background` (default `True`): run the check in a separate thread. Set to `False` to run immediately.

- `raise_exceptions` (default: `False`): if `True`, allow exceptions to bubble to the top. Otherwise, show a warning including the exception message. If `background` is `True` and this is `True` then this will result in a full traceback showing but the process continuing.

## Lower level API

    from outdated import check_outdated

    is_outdated, latest_version = check_outdated('my-package-name', '1.2.3')

    

`is_outdated` is a boolean which is True if the given version is earlier than the latest version, which is the string `latest_version`.

Optional arguments:

- `repository_url` (default `https://pypi.python.org/pypi/%s/json`): a `%` style format string to use a different repository PyPI repository URL, e.g. test.pypi.org or a private repository. The string is formatted with the package name.

This still makes the HTTP call with retries and caches the result on disk. It doesn't use a separate thread or emit any warnings (unless there is an exception specifically while using the cache, in which case the check will be done without the cache).

## Additional configuration

To disable all warnings from this library, set the environment variable `OUTDATED_IGNORE` to any non-empty value.

To always raise exceptions instead of converting them to warnings (both in general in `warn_if_outdated` and more specifically when there's a caching problem) set the environment variable `OUTDATED_RAISE_EXCEPTION=1`.

The warnings are also categorised so that you can easily control them with standard [warning filters](https://docs.python.org/3/library/warnings.html#the-warnings-filter). The classes are [here](https://github.com/alexmojaki/outdated/blob/master/outdated/mywarnings.py) and can be imported directly from the `outdated` module.

## Performance

This library works by fetching a URL such as [this](https://pypi.python.org/pypi/requests/json) - the time it takes to visit that link is essentially the speed of the library. This is much faster than the command `pip list --outdated` or any equivalent code.
