How to get short option name from long option name in vim

I have a list of vim long option names as strings (e.g. ["tabstop","shiftwidth"]). What would be the best way to convert it into a list containing only short names (e.g. ["ts,"sw"]). What about if the original list i开发者_Python百科s a mix of short and long names?

Happy vimming!

I don't believe there's a straightforward way to do this. My best suggestion is to use this little python script to generate a Vim hash:

#!/usr/bin/python
# Assumes the vim source code is available in ./vim_src
# save this as vimoptions.py
import re
import os
vim_src_dir = './vim_src'
matcher = re.compile(r'^\s*{"(?P<longname>[^"]+)",\s*"(?P<shortname>[^"]+)",')
fh = open(os.path.join(vim_src_dir, 'src/option.c')
option_dict = {}
for line in fh:
    m = matcher.match(line)
    if m is not None:
        option_dict[m.group('longname')] = m.group('shortname')
fh.close()
print "let option_dict = {"
for key, value in option_dict.iteritems():
    print '\t\t\t\\ "%s": "%s",' % (key, value)
print '\t\t\t\\ }'

Run it with python vimoptions.py > vimoptions.vim

Then open vim and :source vimoptions.vim. You can then do something like this to convert your list (assuming the list is a variable rather than text: edit as appropriate if this isn't true):

for index in range(len(optlist))
    if has_key(option_dict, optlist[index])
        let optlist[index] = option_dict[optlist[index]]
    endif
endfor

The python code is a bit flaky (it assumes a fairly rigid syntax in the options.c file). If I wanted this to be more robust and maintainable, I'd use the python C API to compile options.c into a python module and import the table into some python code for parsing. That may be a lot more hassle than you really need right now though.
