 Posted: Sat Jul 21, 2007 9:34 pm Post subject: Vim Howto: automatic file skeleton/template creation |
 |
|
If you are not sure what I am talking about, run the following and bask in the glory of Vim! (in the unlikely event of nothing happening, emerge app-vim/gentoo-syntax and retry)
Have you ever been in a situation where you had to type the same thing whenever you created a new file of some kind? For example, whenever I start writing a new Python file, they always look like this:
| Code: | #!/usr/bin/env python
def main():
pass
if __name__ == "__main__":
main() |
It used to be that file creation with "gvim foo.py" invariably would be followed by typing the above template. No more. Now Vim does it for me. This is my story.
edit: what comes below is not the proper way to create skeletons. Next post shows how to do it properly. I didn't remove example below in case somebody finds it useful for other purposes.
The simplest way (I know of) to get vim to fill out a new file template/skeleton is for you is to make your ~/.vim/filetype.vim look something like this:
| Code: |
" The following prevents the file from being executed multiple times
" I am not sure why that happens
if exists("did_load_filetypes")
finish
endif
" below is a function definition.
" '!' means to that this function will overwrite functions with the same
" name if they exist
fun! PySkel()
" 0 put means put on the very first line. otherwise vim will start
" with second.
" You have to use single quotes;
" Most of escape characters didn't work for me
0 put ='#!/usr/bin/env python'
put =''
put =''
put ='def main():'
put =' pass'
put =''
put ='if __name__ == \"__main__\":'
put =' main()'
endfun
"defining a new 'auto command' group
augroup newPy
"when buffer for a new file that matches *.py is created,
" run PySkel()
au BufNewFile *.py call PySkel()
augroup END |
The example above is suboptimal in many ways, but it's the best I can do and it's 100% functional.
Feel free to contribute suggestions and templates

Another way to do this is to create a file that you want to use as a skeleton, e.g. make a ~/.vim/skeleton/skeleton.py that contains the exact text you want to use. Then a single line in your ~/.vimrc something like:
| Code: | | au BufNewFile *.py 0r ~/.vim/skeleton/skeleton.py |
See also :h skeleton. This has the benefit of being somewhat more readable and maintainable in that your skeleton is a real .py file instead of a bunch of inlined strings.
One thing I don't like is that 0r places the cursor on the first line, which generally isn't where you want to start typing. You can always move the cursor to where you want it (e.g. last line) via
| Code: | | au BufNewFile *.py 0r ~/.vim/skeleton/skeleton.py|norm G |

Thank you!
I've been wondering how to do this for a long time, but never took to time to search!
This will save me some typing!
