" guru.vim -- Vim integration for the Go guru.
|
|
"
|
|
" Load with (e.g.) :source guru.vim
|
|
" Call with (e.g.) :GoGuruDescribe
|
|
" while cursor or selection is over syntax of interest.
|
|
" Run :copen to show the quick-fix file.
|
|
"
|
|
" This is an absolutely rudimentary integration of the Go Guru into
|
|
" Vim's quickfix mechanism and it needs a number of usability
|
|
" improvements before it can be practically useful to Vim users.
|
|
" Voluntary contributions welcomed!
|
|
"
|
|
" TODO(adonovan):
|
|
" - reject buffers with no filename.
|
|
" - hide all filenames in quickfix buffer.
|
|
|
|
" Get the path to the Go guru executable.
