Run and manage per-project shell commands with project.el

• upstream on sourcehut: https://git.sr.ht/~alex-iam/epx
• mirror on github: https://github.com/alex-iam/epx

epx.el helps you define, manage, and run shell commands specific to your Emacs projects (those recognized by project.el).

It stores named commands, along with optional environment variables and a flag to use compilation-mode, directly in each project's root: in .dir-locals.el or .epx.eld file. You get interactive commands to easily add, remove, and run these project tasks.

• Completion prompt for commands defined in the current project.
• Re-uses an existing shell window or opens one with project-shell.
• Can run the command in compilation-mode instead of a shell.
• Can use either .dir-locals.el or a dedicated .epx.eld to store commands.
• Command storage can be customized by epx-commands-file-type variable (globally).
• Pure Elisp, only depends on built-in project.

epx can be installed from MELPA. A common way to setup the package using use-package is:

(use-package epx
  :after project
  :bind
  ("C-c p r" . #'epx-run-command-in-shell)
  ("C-c p c" . #'epx-add-command)
  ("C-c p d" . #'epx-remove-command))

You can also always install the package using M-x package-install instead.

• You can use variable epx-commands-file-type to control where your commands are stored. It accepts the following values: ’locals and ’eld.

• epx-add-command : Prompt for a command, name, env vars, and whether to use a compilation buffer; writes it to commands file.

• epx-run-command-in-shell : Pick a saved command and execute it in a shell (or compilation) buffer scoped to the project.

• epx-remove-command : Remove a saved command from .dir-locals.el.

((nil . ((local-project-cmds ;; This is the variable epx looks for
          . ((:name "lint"
              :command "ruff check ."
              :compile t)))))

((:name "lint"
  :command "ruff check ."
  :compile t))

With this entry present in your project root's commands file, running M-x epx-run-command-in-shell RET lint RET will execute ruff check . in a compilation-mode buffer, using your project's root as the working directory.
