mastodon-py 1.5.1 uses a dot in its dist-info dir name, which we
previously didn't handle, causing home-assistant to fail. The new
implementation is based on
2f83540272/src/packaging/utils.py (L146-L172).
Part of #199

puffin
An experimental Python packaging tool.
Motivation
Puffin is an extremely fast (experimental) Python package resolver and installer, intended to
replace pip and pip-tools (pip-compile and pip-sync).
Puffin itself is not a complete "package manager", but rather a tool for locking dependencies
(similar to pip-compile) and installing them (similar to pip-sync). Puffin can be used to
generate a set of locked dependencies from a requirements.txt file, and then install those
locked dependencies into a virtual environment.
Puffin represents an intermediary goal in our pursuit of building a "Cargo for Python": a Python
package manager that is extremely fast, reliable, and easy to use -- capable of replacing not only
pip, but also pipx, pip-tools, virtualenv, tox, setuptools, and even pyenv, by way of
managing the Python installation itself.
Puffin's limited scope allows us to solve many of the low-level problems that are required to
build such a package manager (like package installation) while shipping an immediately useful tool
with a minimal barrier to adoption. Try it today in lieu of pip and pip-tools.
Features
- Extremely fast dependency resolution and installation: install dependencies in sub-second time.
- Disk-space efficient: Puffin uses a global cache to deduplicate dependencies, and uses Copy-on-Write on supported filesystems to reduce disk usage.
Limitations
Puffin does not yet support:
- Source distributions
- VCS dependencies
- URL dependencies
- Windows
- ...
Like pip-compile, Puffin generates a platform-specific requirements.txt file (unlike, e.g.,
poetry, which generates a platform-agnostic poetry.lock file). As such, Puffin's
requirements.txt files are not portable across platforms and Python versions.
Usage
To resolve a requirements.in file:
cargo run -p puffin-cli -- pip-compile requirements.in
To install from a resolved requirements.txt file:
cargo run -p puffin-cli -- pip-sync requirements.txt
For more, see cargo run -p puffin-cli -- --help:
Usage: puffin-cli <COMMAND>
Commands:
compile Compile a `requirements.in` file to a `requirements.txt` file
sync Sync dependencies from a `requirements.txt` file
clean Clear the cache
freeze Enumerate the installed packages in the current environment
help Print this message or the help of the given subcommand(s)
Options:
-h, --help Print help
-V, --version Print version
