As I am typing code, I would like to get the symbol before and after a specific character (e.g. ‘.’ in C#) and pass that to my own program which would then in return give a list of possible completions.
For example if user is typing:
m_Filename.M
I would want to call out into my own DLL/EXE passing “m_Filename” and “M” and my program return a list such as
Match
Matches
And have that popup in a list in ViM for autocompletion suggestions.
Note that this is not asking how to write the DLL/EXE which provides the suggestions, just the functionality in ViM for autocomplete .
In vim, see
:help 'omnifunc'and:help complete-functions. You can write your own vim function to do completions, and that function can, in turn, invoke an external executable.
