I recently took over maintaining this project. I actively use this package with GNU Emacs 29.3 and poetry 1.8.2 on macOS.

[[https://python-poetry.org][Poetry]] in Emacs.

From Poetry documentation: "Poetry is a tool for dependency management and packaging in Python. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you."

~poetry.el~ is a wrapper around Poetry, offering a simple an intuitive interface in Emacs.

** Installation

*** From Melpa

poetry.el is available on Melpa, the most straightforward way of installing it is to use ~use-package~:

+BEGIN_SRC elisp

(use-package poetry :ensure t)

+END_SRC

*** Manually

  1. Dependencies

    poetry.el needs ~transient~ and ~pyvenv~ to be installed. These packages are both available on MELPA.

  2. Clone the ~poetry.el~ repository:

    +BEGIN_SRC bash

    $ git clone https://github.com/cybniv/poetry.el /path/to/poetry.el

    +END_SRC

  3. Add the following lines to ~.emacs.el~ (or equivalent):

    +BEGIN_SRC elisp

    (add-to-list 'load-path "/path/to/poetry.el") (require 'poetry)

    +END_SRC

** Usage

poetry.el uses [[https://github.com/magit/transient][transient]] to provide a magit-like interface. The entry point is simply:

+BEGIN_SRC elisp

M-x poetry

+END_SRC

The interface should then be pretty much self-explanatory for poetry users:

+attr_html: :width 400px

For users not familiar with how ~Poetry~ works, the [[https://python-poetry.org/docs/][documentation]] is a great place to start.

*** Tracking Poetry virtualenv ~poetry.el~ also provides a global minor mode that automatically activate the correct virtualenv when visiting Poetry project files. You can activate this feature with:

+BEGIN_SRC elisp

M-x poetry-tracking-mode

+END_SRC

By default, poetry.el checks if the virtualenv needs to be updated after every command. It has the advantage of always providing the right virtualenv, but can be annoyingly slow. You can change the strategy poetry.el uses through the ~poetry-tracking-strategy~.
