27 | ;;; Commentary: | |
28 | ||
29 | ;; Major mode for editing Python files with some fontification and | |
30 | ;; indentation bits extracted from original Dave Love's python.el | |
31 | ;; found in GNU/Emacs. | |
32 | ||
45c138ac | 33 | ;; Implements Syntax highlighting, Indentation, Movement, Shell |
64348c32 FEG |
34 | ;; interaction, Shell completion, Shell virtualenv support, Pdb |
35 | ;; tracking, Symbol completion, Skeletons, FFAP, Code Check, Eldoc, | |
207cb73c | 36 | ;; Imenu. |
45c138ac FEG |
37 | |
38 | ;; Syntax highlighting: Fontification of code is provided and supports | |
39 | ;; python's triple quoted strings properly. | |
40 | ||
41 | ;; Indentation: Automatic indentation with indentation cycling is | |
42 | ;; provided, it allows you to navigate different available levels of | |
67845102 FEG |
43 | ;; indentation by hitting <tab> several times. Also when inserting a |
44 | ;; colon the `python-indent-electric-colon' command is invoked and | |
45 | ;; causes the current line to be dedented automatically if needed. | |
45c138ac FEG |
46 | |
47 | ;; Movement: `beginning-of-defun' and `end-of-defun' functions are | |
fc6c545e | 48 | ;; properly implemented. There are also specialized |
032d23ab FEG |
49 | ;; `forward-sentence' and `backward-sentence' replacements called |
50 | ;; `python-nav-forward-block', `python-nav-backward-block' | |
51 | ;; respectively which navigate between beginning of blocks of code. | |
52 | ;; Extra functions `python-nav-forward-statement', | |
bcdc27d7 FEG |
53 | ;; `python-nav-backward-statement', |
54 | ;; `python-nav-beginning-of-statement', `python-nav-end-of-statement', | |
55 | ;; `python-nav-beginning-of-block' and `python-nav-end-of-block' are | |
56 | ;; included but no bound to any key. At last but not least the | |
489af14f | 57 | ;; specialized `python-nav-forward-sexp' allows easy |
bcdc27d7 | 58 | ;; navigation between code blocks. |
45c138ac | 59 | |
fc6c545e | 60 | ;; Shell interaction: is provided and allows you to execute easily any |
45c138ac FEG |
61 | ;; block of code of your current buffer in an inferior Python process. |
62 | ||
63 | ;; Shell completion: hitting tab will try to complete the current | |
4e531f7a | 64 | ;; word. Shell completion is implemented in a manner that if you |
45c138ac FEG |
65 | ;; change the `python-shell-interpreter' to any other (for example |
66 | ;; IPython) it should be easy to integrate another way to calculate | |
57808175 | 67 | ;; completions. You just need to specify your custom |
45c138ac | 68 | ;; `python-shell-completion-setup-code' and |
4cafacb5 | 69 | ;; `python-shell-completion-string-code'. |

70 | |
71 | ;; Here is a complete example of the settings you would use for | |
1faf2911 | 72 | ;; iPython 0.11: |
62feb915 FEG |
73 | |
74 | ;; (setq | |
75 | ;; python-shell-interpreter "ipython" | |
76 | ;; python-shell-interpreter-args "" | |
77 | ;; python-shell-prompt-regexp "In \\[[0-9]+\\]: " | |
78 | ;; python-shell-prompt-output-regexp "Out\\[[0-9]+\\]: " | |
9399498e FEG |
79 | ;; python-shell-completion-setup-code |
80 | ;; "from IPython.core.completerlib import module_completion" | |
f6b59cd1 | 81 | ;; python-shell-completion-module-string-code |
9399498e | 82 | ;; "';'.join(module_completion('''%s'''))\n" |
62feb915 | 83 | ;; python-shell-completion-string-code |
9399498e | 84 | ;; "';'.join(get_ipython().Completer.all_completions('''%s'''))\n") |
1faf2911 FEG |
85 | |
86 | ;; For iPython 0.10 everything would be the same except for | |
936bc833 FEG |
87 | ;; `python-shell-completion-string-code' and |
88 | ;; `python-shell-completion-module-string-code': | |
1faf2911 FEG |
89 | |
90 | ;; (setq python-shell-completion-string-code | |
936bc833 FEG |
91 | ;; "';'.join(__IP.complete('''%s'''))\n" |
92 | ;; python-shell-completion-module-string-code "") | |
45c138ac | 93 | |

94 | ;; Unfortunately running iPython on Windows needs some more tweaking. |
95 | ;; The way you must set `python-shell-interpreter' and | |
96 | ;; `python-shell-interpreter-args' is as follows: | |
97 | ||
98 | ;; (setq | |
99 | ;; python-shell-interpreter "C:\\Python27\\python.exe" | |
100 | ;; python-shell-interpreter-args | |
101 | ;; "-i C:\\Python27\\Scripts\\ipython-script.py") | |
102 | ||
103 | ;; That will spawn the iPython process correctly (Of course you need | |
104 | ;; to modify the paths according to your system). | |
105 | ||
099bf010 FEG |
106 | ;; Please note that the default completion system depends on the |
107 | ;; readline module, so if you are using some Operating System that | |
108 | ;; bundles Python without it (like Windows) just install the | |
109 | ;; pyreadline from http://ipython.scipy.org/moin/PyReadline/Intro and | |
110 | ;; you should be good to go. | |
111 | ||
64348c32 FEG |
112 | ;; Shell virtualenv support: The shell also contains support for |
113 | ;; virtualenvs and other special environment modifications thanks to | |
66bbb27f FEG |
114 | ;; `python-shell-process-environment' and `python-shell-exec-path'. |
115 | ;; These two variables allows you to modify execution paths and | |
307bd2e8 | 116 | ;; environment variables to make easy for you to setup virtualenv rules |
64348c32 | 117 | ;; or behavior modifications when running shells. Here is an example |
66bbb27f FEG |
118 | ;; of how to make shell processes to be run using the /path/to/env/ |
119 | ;; virtualenv: | |
120 | ||
121 | ;; (setq python-shell-process-environment | |
122 | ;; (list | |
123 | ;; (format "PATH=%s" (mapconcat | |
124 | ;; 'identity | |
125 | ;; (reverse | |
126 | ;; (cons (getenv "PATH") | |
127 | ;; '("/path/to/env/bin/"))) | |
128 | ;; ":")) | |
129 | ;; "VIRTUAL_ENV=/path/to/env/")) | |
130 | ;; (python-shell-exec-path . ("/path/to/env/bin/")) | |
131 | ||
48d1354e | 132 | ;; Since the above is cumbersome and can be programmatically |
64348c32 FEG |
133 | ;; calculated, the variable `python-shell-virtualenv-path' is |
134 | ;; provided. When this variable is set with the path of the | |
135 | ;; virtualenv to use, `process-environment' and `exec-path' get proper | |
136 | ;; values in order to run shells inside the specified virtualenv. So | |
137 | ;; the following will achieve the same as the previous example: | |
138 | ||
139 | ;; (setq python-shell-virtualenv-path "/path/to/env/") | |
140 | ||
929036b4 FEG |
141 | ;; Also the `python-shell-extra-pythonpaths' variable have been |
142 | ;; introduced as simple way of adding paths to the PYTHONPATH without | |
143 | ;; affecting existing values. | |
144 | ||
45c138ac FEG |
145 | ;; Pdb tracking: when you execute a block of code that contains some |
146 | ;; call to pdb (or ipdb) it will prompt the block of code and will | |
147 | ;; follow the execution of pdb marking the current line with an arrow. | |
148 | ||
4e531f7a | 149 | ;; Symbol completion: you can complete the symbol at point. It uses |
45c138ac FEG |
150 | ;; the shell completion in background so you should run |
151 | ;; `python-shell-send-buffer' from time to time to get better results. | |
152 | ||
e2803784 FEG |
153 | ;; Skeletons: 6 skeletons are provided for simple inserting of class, |
154 | ;; def, for, if, try and while. These skeletons are integrated with | |
155 | ;; dabbrev. If you have `dabbrev-mode' activated and | |
156 | ;; `python-skeleton-autoinsert' is set to t, then whenever you type | |
157 | ;; the name of any of those defined and hit SPC, they will be | |
345f866e FEG |
158 | ;; automatically expanded. As an alternative you can use the defined |
159 | ;; skeleton commands: `python-skeleton-class', `python-skeleton-def' | |
160 | ;; `python-skeleton-for', `python-skeleton-if', `python-skeleton-try' | |
161 | ;; and `python-skeleton-while'. | |
e2803784 | 162 | |
2947016a FEG |
163 | ;; FFAP: You can find the filename for a given module when using ffap |
164 | ;; out of the box. This feature needs an inferior python shell | |
165 | ;; running. | |
166 | ||
2d63ad56 FEG |
167 | ;; Code check: Check the current file for errors with `python-check' |
168 | ;; using the program defined in `python-check-command'. | |
8b3e0e76 | 169 | |
45c138ac | 170 | ;; Eldoc: returns documentation for object at point by using the |
4e531f7a | 171 | ;; inferior python subprocess to inspect its documentation. As you |
45c138ac FEG |
172 | ;; might guessed you should run `python-shell-send-buffer' from time |
173 | ;; to time to get better results too. | |
174 | ||
207cb73c | 175 | ;; Imenu: This mode supports Imenu in its most basic form, letting it |
758e556a FEG |
176 | ;; build the necessary alist via `imenu-default-create-index-function' |
177 | ;; by having set `imenu-extract-index-name-function' to | |
207cb73c FEG |
178 | ;; `python-info-current-defun' and |
179 | ;; `imenu-prev-index-position-function' to | |
180 | ;; `python-imenu-prev-index-position'. | |

182 | ;; If you used python-mode.el you probably will miss auto-indentation |
183 | ;; when inserting newlines. To achieve the same behavior you have | |
184 | ;; two options: | |
185 | ||
186 | ;; 1) Use GNU/Emacs' standard binding for `newline-and-indent': C-j. | |
187 | ||
188 | ;; 2) Add the following hook in your .emacs: | |
189 | ||
190 | ;; (add-hook 'python-mode-hook | |
191 | ;; #'(lambda () | |
192 | ;; (define-key python-mode-map "\C-m" 'newline-and-indent))) | |
193 | ||
194 | ;; I'd recommend the first one since you'll get the same behavior for | |
195 | ;; all modes out-of-the-box. | |
