" netrw_gitignore#Hide: gitignore-based hiding
|

" Function returns a string of comma separated patterns convenient for
|

" Function can take additional filenames as arguments, example:
|
|
" netrw_gitignore#Hide('custom_gitignore1', 'custom_gitignore2')
|
|
"
|
|
" Usage examples:
|
|
" let g:netrw_list_hide = netrw_gitignore#Hide()
