Editing ProgrammingWithPythonDotEl

There are two major variants of ##python.el## * [https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/python.el the official python.el]. See [[ProgrammingWithPythonDotElGallina]] for more information. * [http://www.loveshack.ukfsn.org/emacs/python.el 'loveshack' python.el], which this page refers to, was used in Emacs 24.1 and before. This is now maintained at https://github.com/leoliu/python-el; "feature requests and bug reports are welcome. I'll try my best to fix them. - Leo" * "the main raison d'être for python.el was that we couldn't get copyright papers for python-mode.el for inclusion in Emacs [http://mail.python.org/pipermail/python-mode/2009-January/000514.html]. == YaSnippet === see [http://groups.google.com/group/smart-snippet/browse_thread/thread/d1eae085ceebf839 this post] == Documentation === 'python-describe-symbol' tries to get doc in the context of what the source file imports (be sure to first run the Python interpreter [C-c !]). ElDoc, : Does it work with python.el? python.el is supposed to have superior support for this, but I can't get it to work; it worked alright in python-mode.el though! -- CH :: nevermind, it works now. shows up in the mini-buffer when you type a function name. -- CH :: It may have stopped working when my 'imports' were incomplete. check that the computed value of 'python-imports' is sensible! --CH == CEDET == [[CEDET]] is now part of emacs (but I still recommend getting the latest version). It includes things like completion and folding, so that some things here may not be required. == Indentation and folding === python.el includes a regexp for outliner-mode, and hs-mode too. Since indentation is significant in python, correct indent functions are vital, thought these might overload the tab key. : guess indent? or do something! maybe a 'fix syntax' key? py-smart? -- CH : tab to guess or max indent, backspace to reduce? This appear to be a function already. -- CH See SmartTabs (toc5) or TabCompletion (tabkey2 stuff) === Newline-and-indent === In python.el you can get this with this in your InitFile: (add-hook 'python-mode-hook '(lambda () (define-key python-mode-map "\C-m" 'newline-and-indent))) == Useful Functions === python-end-of-block instead of py-next-block? == auto-complete == The following will integrate python.el completions with auto-complete. You need to have installed and loaded auto-complete.el first: (defvar ac-source-python '((candidates . (lambda () (mapcar '(lambda (completion) (first (last (split-string completion "\\." t)))) (python-symbol-completions (python-partial-symbol))))))) (add-hook 'python-mode-hook (lambda() (setq ac-sources '(ac-source-python)))) == Troubleshooting == === C-c C-c / C-c C-r doesn't send / evaluate my code! === It seems like point has to be at the very bottom, with a clear prompt, for python-send-region to work. Here's a quick hack that does that before calling the function, and puts it back the way it was afterwards: (defadvice python-send-region (around advice-python-send-region-goto-end) "Fix a little bug if the point is not at the prompt when you do C-c C-[rc]" (let ((oldpoint (with-current-buffer (process-buffer (python-proc)) (point))) (oldinput (with-current-buffer (process-buffer (python-proc)) (goto-char (point-max)) ;; Do C-c C-u, but without modifying the kill ring: (let ((pmark (process-mark (get-buffer-process (current-buffer))))) (when (> (point) (marker-position pmark)) (let ((ret (buffer-substring pmark (point)))) (delete-region pmark (point)) ret)))))) ad-do-it (with-current-buffer (process-buffer (python-proc)) (when oldinput (insert oldinput)) (goto-char oldpoint)))) (ad-enable-advice 'python-send-region 'around 'advice-python-send-region-goto-end) (ad-activate 'python-send-region) === python-complete-symbol === Using python-complete-symbol in the inferior python buffer causes an infinite loop in python.el as of 080117, changing python-imports from the default nil to 'None' solves this. 2008-01-17, patch submitted. === py-help-at-point bug === :I'm a little confused - It appears when I set flymake-mode to be automatically on for python mode, py-help-at-point doesn't™t work. I tried switching from python-mode.el to python.el, but this doesn't seem to solve it; However, there is no advice here on *how* to use python.el, so I'm not entirely sure I'm doing it right... :: The above refers to python.el as packaged with Emacs 22; loveshack- python.el completion can't generally work in the inferior buffer because it sends input to that buffer. The loveshack- python.el doesn't actually define python-complete-symbol. You can use the interpreter rlcompleter module as normal if you want.
