Improve Python setup codes to avoid leaving global names

2026-03-07T11:32:11Z

* lisp/progmodes/python.el (python-shell-setup-code) (python-shell-readline-detect): Improve Python code. (Bug#80551)

Use a custom Pdb class in the Python shell

2026-02-21T14:51:28Z

The custom Pdb class enables native completion in pdb by wrapping the pdb's native completer. It also makes necessary function definitions like __PYTHON_EL_* available between pdb frames, and enables non-native completion/ffap/eldoc functionalities when debugging inside python modules. * lisp/progmodes/python.el (python-shell-send-setup-code): Fix the separator between python-shell-setup-codes. (python-shell-completion-native-setup): Move common completion setup code ... (python-shell-completion-setup-code): ... here. (python-shell-completion-at-point): Enable native completion for pdb and respect the delimiter of pdb completer. (python-shell-pdb-setup-code): New variable. (python-shell-comint-watch-for-first-prompt-output-filter): Send setup codes only once. (python-ffap-module-path, python-eldoc--get-doc-at-point): Stop sending setup code in every function call. * test/lisp/progmodes/python-tests.el (python-tests--pdb-1) (python-shell-pdb-1): New test. * etc/NEWS: Mention the change. (bug#80182)

Remove (featurep 'project) guards in python.el

2026-02-19T17:36:52Z

* lisp/progmodes/python.el: Since they are included in emacs 29.1, remove the Package-Requires for seq, project, and flymake. (require 'project): Remove 'noerror argument. (python-shell-get-process-name): Remove (featurep 'project). Use 'project-name'. (run-python) (python--import-sources): Remove (featurep 'project). (Bug#80405)

Revert "Use 'project-name-cached' in 'python-shell-get-process-name'"

2026-02-13T07:43:29Z

This reverts commit 482748592f61abed6f675e7b62b2d56e4e18a146. Commit 583a112169f0c964552b94f84ea0c942377a14e6 removed 'project-name-cached' and also resolved bug#80045.

Change the type of 'python-eldoc-function-timeout' to number

2026-02-07T12:44:27Z

* etc/NEWS: Announce the change. * lisp/progmodes/python.el (python-eldoc-function-timeout): Change the type. (Bug#80045)

Use 'project-name-cached' in 'python-shell-get-process-name'

2026-02-07T12:41:48Z

* lisp/progmodes/python.el (python-shell-get-project-name): New function. (python-shell-get-process-name): Use it. (Bug#80045) Co-authored-by: Liu Hui

Revert "Performance improvement of 'python-shell-get-process'"

2026-02-07T12:41:10Z

This reverts commit 83b4f1ba26844c178e57ecb93ea8db36e8e6fa89. We concluded that it is better to use 'project-name-cached'. (Bug#80045)

Fix down-list navigation in python-ts-mode

2026-01-21T18:02:56Z

* lisp/progmodes/python.el (python-ts-mode): Set 'treesit-sexp-thing-down-list' to 'list' to override sexp navigation with list navigation (bug#72478). * lisp/emacs-lisp/lisp.el (up-list): Mention 'up-list-function' in docstring.

Performance improvement of 'python-shell-get-process'

2026-01-17T16:09:03Z

'python-shell-get-process' is frequently called from 'python-eldoc--get-doc-at-point' and etc., invoking 'project-current' unless there is a buffer-specific Inferior Python process. When the buffer is a remote buffer not belonging to any project and has significant latency, 'project-current' may take a long time. To avoid this, implement a process cache in 'python-shell-get-process'. * lisp/progmodes/python.el (python-shell--process-cache) (python-shell--process-cache-valid): New variables. (python-shell--invalidate-process-cache): New function. (python-shell-make-comint): Add a call to the above function. (python-shell-get-process): Add process cache. (Bug#80045)
