Question

I have a plugin function called InComment() stored in magic.vim *1

I would like to share it between two ftplugin files:

• ftplugin/c.vim
• ftplugin/python.vim

What is the idiomatic way to call InComment() function from my ftplugin files?

*1 plugin/magic.vim

function! s:InComment() " {{{
    let syn = s:SyntaxName(line('.'), col('.') - 1, 1)
    if syn =~? 'comment'
        return 1
    else
        return 0
    endif
endfunction "}}}

Answer 1

The document referenced by Prince Goulash has everything you need. To answer you specifically, you need to give the function a name based on the name of your plugin, like this:

function! magic#InComment() " {{{
    let syn = s:SyntaxName(line('.'), col('.') - 1, 1)
    if syn =~? 'comment'
        return 1
    else
        return 0
    endif
endfunction "}}}

Then you can call it from your plugin like this:

call magic#InComment()

The part before the # has to match the name of your plugin file. This will also cause the plugin to be autoloaded when the function is called.
