|
8 " USAGE: |
|
9 " |
|
10 " Save this file to $VIMFILES/ftplugin/python.vim. You can have multiple |
|
11 " python ftplugins by creating $VIMFILES/ftplugin/python and saving your |
|
12 " ftplugins in that directory. If saving this to the global ftplugin |
|
13 " directory, this is the recommended method, since vim ships with an |
|
14 " ftplugin/python.vim file already. |
|
15 " You can set the global variable "g:py_select_leading_comments" to 0 |
|
16 " if you don't want to select comments preceding a declaration (these |
|
17 " are usually the description of the function/class). |
|
18 " You can set the global variable "g:py_select_trailing_comments" to 0 |
|
19 " if you don't want to select comments at the end of a function/class. |
|
20 " If these variables are not defined, both leading and trailing comments |
|
21 " are selected. |
|
22 " Example: (in your .vimrc) "let g:py_select_leading_comments = 0" |
|
23 " You may want to take a look at the 'shiftwidth' option for the |
|
24 " shift commands... |
