Non-nil, forces display of a user-friendly message if there's no
When called interactively SEND-MAIN defaults to nil, unless it'sĬalled with prefix argument. When optional argument SEND-MAIN is non-nil, allow execution ofĬode inside blocks delimited by \"if _name_= \\='_main_\\=':\". "Send the entire line to inferior Python process. The following function is essentially a copy of python-shell-send-buffer (defun python-shell-send-line (&optional send-main msg) You can send the whole region with C-c C-r and you can send the current line that you are by binding the following function. To send the whole buffer you can press C-c C-c. I can't imagine having to copy and paste every function into the shell.
Getting the function to run directly from the script to the shell would be ideal. Override the auto-indent preference by setting autoindent to never to avoid indent. However, when I copy the function and paste it directly into the IPython shell: > def convert(x): Alt-Return: new-line - Place a new line at the current cursor position. IndentationError: expected an indented block To get started with your 'Lisp degree', type C-h i for the Info browser and go to the node for 'CC Mode' (it is separate from the node for Emacs type d for Directory and find CC Mode there). Into the script (4-space indentation) and press Ctrl-Enter twice I get: >. When I type the function: import numpy as np
PYTHON INDENT BLOCK EMACS CODE
My setup is side-by-side windows, on the left is a buffer(script) where I write/edit the code which then gets sent to the IPython shell on the right with Ctrl-Enter. (I know it doesn't sound like much, but try re-indenting 100 lines of garbage literal without missing down-arrow, and then having to go up 5 lines and repeat things ) ).I made the switch to Emacs.
Or you can do C-u 10 C-x e to apply it 10 times. So what I've been doing in such cases is quickly recording a keyboard macro like C-n TAB as in F3, Ctrl-n (or down arrow), TAB, F4, and then using F4 repeatedly to apply the macro can save a couple of keystrokes. It feels like M-x indent-region should do something sensibly in python-mode, but that's not (yet) the case.įor the specific case where your literals are bracketed, using TAB on the lines in question gets what you want (because whitespace doesn't play a role). M-x indent-region or M-x python-indent-shift-right and company aren't going to help if you've cut-and-pasted the following literal and need it to be re-indented sensibly: foo = None of the answers mentioned so far cover re-indentation of literals like dict or list. I'm an Emacs newb, so this answer it probably bordering on useless. Now inside an Org mode buffer, the value of that variable is org-indent-line, which, in source code blocks, calls org-babel-do-key-sequence-in-edit-buffer that in turn calls. Unindents to the next multiple of the current tab-width" (interactive) (let ((deactivate-mark nil) (beg (or (and mark-active (region-beginning)) (line-beginning-position))) (end (or (and mark-active (region-end)) (line-end-position))) (min-indentation) (count (or count-arg 1))) (save-excursion (goto-char beg) (while ( 0 count) (indent-rigidly beg end (* (- 0 tab-width) count)) (let ( (indent-amount (apply 'min (mapcar (lambda (x) (- 0 (mod x tab-width))) min-indentation)))) (indent-rigidly beg end (or (and (< indent-amount 0) indent-amount) (* (or count 1) (- 0 tab-width))))))))Īnd then I assign it to a keyboard shortcut: (global-set-key (kbd "s-") (lambda () (interactive) (unindent-dwim -1))) EDIT 3: I stand corrected: you should expect 'real' python indentation: indent-for-tab-command calls the function which is the value of the variable indent-line-function. I've been using this function to handle my indenting and unindenting: (defun unindent-dwim (&optional count-arg) "Keeps relative spacing in the region.
PYTHON INDENT BLOCK EMACS INSTALL
py files, simply install the python-mode package. With Ubuntu, to make python-mode the default mode for all. With python-mode, after marking the block of code,Ĭ-c > or C-c C-l shifts the region 4 spaces to the rightĬ-c shifts the region 8 spaces to the right If you are programming Python using Emacs, then you should probably be using python-mode.
