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 | ||
33 | ;; While it probably has less features than Dave Love's python.el and | |
34 | ;; PSF's python-mode.el it provides the main stuff you'll need while | |
35 | ;; keeping it simple :) | |
36 | ||
37 | ;; Implements Syntax highlighting, Indentation, Movement, Shell | |
64348c32 FEG |
38 | ;; interaction, Shell completion, Shell virtualenv support, Pdb |
39 | ;; tracking, Symbol completion, Skeletons, FFAP, Code Check, Eldoc, | |
40 | ;; imenu. | |
45c138ac FEG |
41 | |
42 | ;; Syntax highlighting: Fontification of code is provided and supports | |
43 | ;; python's triple quoted strings properly. | |
44 | ||
45 | ;; Indentation: Automatic indentation with indentation cycling is | |
46 | ;; provided, it allows you to navigate different available levels of | |
67845102 FEG |
47 | ;; indentation by hitting <tab> several times. Also when inserting a |
48 | ;; colon the `python-indent-electric-colon' command is invoked and | |
49 | ;; causes the current line to be dedented automatically if needed. | |
45c138ac FEG |
50 | |
51 | ;; Movement: `beginning-of-defun' and `end-of-defun' functions are | |
fc6c545e | 52 | ;; properly implemented. There are also specialized |
4cafacb5 FEG |
53 | ;; `forward-sentence' and `backward-sentence' replacements |
54 | ;; (`python-nav-forward-sentence', `python-nav-backward-sentence' | |
55 | ;; respectively). Extra functions `python-nav-sentence-start' and | |
56 | ;; `python-nav-sentence-end' are included to move to the beginning and | |
57 | ;; to the end of a setence while taking care of multiline definitions. | |
fc6c545e FEG |
58 | ;; `python-nav-jump-to-defun' is provided and allows jumping to a |
59 | ;; function or class definition quickly in the current buffer. | |
45c138ac | 60 | |
fc6c545e | 61 | ;; Shell interaction: is provided and allows you to execute easily any |
45c138ac FEG |
62 | ;; block of code of your current buffer in an inferior Python process. |
63 | ||
64 | ;; Shell completion: hitting tab will try to complete the current | |
4e531f7a | 65 | ;; word. Shell completion is implemented in a manner that if you |
45c138ac FEG |
66 | ;; change the `python-shell-interpreter' to any other (for example |
67 | ;; IPython) it should be easy to integrate another way to calculate | |
57808175 | 68 | ;; completions. You just need to specify your custom |
45c138ac | 69 | ;; `python-shell-completion-setup-code' and |
4cafacb5 | 70 | ;; `python-shell-completion-string-code'. |
62feb915 FEG |
71 | |
72 | ;; Here is a complete example of the settings you would use for | |
1faf2911 | 73 | ;; iPython 0.11: |
62feb915 FEG |
74 | |
75 | ;; (setq | |
76 | ;; python-shell-interpreter "ipython" | |
77 | ;; python-shell-interpreter-args "" | |
78 | ;; python-shell-prompt-regexp "In \\[[0-9]+\\]: " | |
79 | ;; python-shell-prompt-output-regexp "Out\\[[0-9]+\\]: " | |
80 | ;; python-shell-completion-setup-code "" | |
81 | ;; python-shell-completion-string-code | |
1faf2911 FEG |
82 | ;; "';'.join(get_ipython().Completer.all_completions('''%s'''))\n") |
83 | ||
84 | ;; For iPython 0.10 everything would be the same except for | |
85 | ;; `python-shell-completion-string-code': | |
86 | ||
87 | ;; (setq python-shell-completion-string-code | |
88 | ;; "';'.join(__IP.complete('''%s'''))\n") | |
45c138ac | 89 | |
099bf010 FEG |
90 | ;; Please note that the default completion system depends on the |
91 | ;; readline module, so if you are using some Operating System that | |
92 | ;; bundles Python without it (like Windows) just install the | |
93 | ;; pyreadline from http://ipython.scipy.org/moin/PyReadline/Intro and | |
94 | ;; you should be good to go. | |
95 | ||
64348c32 FEG |
96 | ;; Shell virtualenv support: The shell also contains support for |
97 | ;; virtualenvs and other special environment modifications thanks to | |
66bbb27f FEG |
98 | ;; `python-shell-process-environment' and `python-shell-exec-path'. |
99 | ;; These two variables allows you to modify execution paths and | |
307bd2e8 | 100 | ;; environment variables to make easy for you to setup virtualenv rules |
64348c32 | 101 | ;; or behavior modifications when running shells. Here is an example |
66bbb27f FEG |
102 | ;; of how to make shell processes to be run using the /path/to/env/ |
103 | ;; virtualenv: | |
104 | ||
105 | ;; (setq python-shell-process-environment | |
106 | ;; (list | |
107 | ;; (format "PATH=%s" (mapconcat | |
108 | ;; 'identity | |
109 | ;; (reverse | |
110 | ;; (cons (getenv "PATH") | |
111 | ;; '("/path/to/env/bin/"))) | |
112 | ;; ":")) | |
113 | ;; "VIRTUAL_ENV=/path/to/env/")) | |
114 | ;; (python-shell-exec-path . ("/path/to/env/bin/")) | |
115 | ||
64348c32 FEG |
116 | ;; Since the above is cumbersome and can be programatically |
117 | ;; calculated, the variable `python-shell-virtualenv-path' is | |
118 | ;; provided. When this variable is set with the path of the | |
119 | ;; virtualenv to use, `process-environment' and `exec-path' get proper | |
120 | ;; values in order to run shells inside the specified virtualenv. So | |
121 | ;; the following will achieve the same as the previous example: | |
122 | ||
123 | ;; (setq python-shell-virtualenv-path "/path/to/env/") | |
124 | ||
929036b4 FEG |
125 | ;; Also the `python-shell-extra-pythonpaths' variable have been |
126 | ;; introduced as simple way of adding paths to the PYTHONPATH without | |
127 | ;; affecting existing values. | |
128 | ||
45c138ac FEG |
129 | ;; Pdb tracking: when you execute a block of code that contains some |
130 | ;; call to pdb (or ipdb) it will prompt the block of code and will | |
131 | ;; follow the execution of pdb marking the current line with an arrow. | |
132 | ||
4e531f7a | 133 | ;; Symbol completion: you can complete the symbol at point. It uses |
45c138ac FEG |
134 | ;; the shell completion in background so you should run |
135 | ;; `python-shell-send-buffer' from time to time to get better results. | |
136 | ||
e2803784 FEG |
137 | ;; Skeletons: 6 skeletons are provided for simple inserting of class, |
138 | ;; def, for, if, try and while. These skeletons are integrated with | |
139 | ;; dabbrev. If you have `dabbrev-mode' activated and | |
140 | ;; `python-skeleton-autoinsert' is set to t, then whenever you type | |
141 | ;; the name of any of those defined and hit SPC, they will be | |
142 | ;; automatically expanded. | |
143 | ||
2947016a FEG |
144 | ;; FFAP: You can find the filename for a given module when using ffap |
145 | ;; out of the box. This feature needs an inferior python shell | |
146 | ;; running. | |
147 | ||
2d63ad56 FEG |
148 | ;; Code check: Check the current file for errors with `python-check' |
149 | ;; using the program defined in `python-check-command'. | |
8b3e0e76 | 150 | |
45c138ac | 151 | ;; Eldoc: returns documentation for object at point by using the |
4e531f7a | 152 | ;; inferior python subprocess to inspect its documentation. As you |
45c138ac FEG |
153 | ;; might guessed you should run `python-shell-send-buffer' from time |
154 | ;; to time to get better results too. | |
155 | ||
4cafacb5 FEG |
156 | ;; imenu: This mode supports imenu. It builds a plain or tree menu |
157 | ;; depending on the value of `python-imenu-make-tree'. Also you can | |
fc2dc7df FEG |
158 | ;; customize if menu items should include its type using |
159 | ;; `python-imenu-include-defun-type'. | |
160 | ||
57808175 FEG |
161 | ;; If you used python-mode.el you probably will miss auto-indentation |
162 | ;; when inserting newlines. To achieve the same behavior you have | |
163 | ;; two options: | |
164 | ||
165 | ;; 1) Use GNU/Emacs' standard binding for `newline-and-indent': C-j. | |
166 | ||
167 | ;; 2) Add the following hook in your .emacs: | |
168 | ||
169 | ;; (add-hook 'python-mode-hook | |
170 | ;; #'(lambda () | |
171 | ;; (define-key python-mode-map "\C-m" 'newline-and-indent))) | |
172 | ||
173 | ;; I'd recommend the first one since you'll get the same behavior for | |
174 | ;; all modes out-of-the-box. | |
175 | ||
