Fzf Hoogle.vim Save
(neo)vim plugin that uses fzf for previewing hoogle search results
fzf-hoogle.vim (works only on Linux and macOS)
(neo)vim plugin that uses fzf for previewing hoogle search results
Requirements
Since v1.2 requires hoogle 5.0.17.13 and above to properly restrict number of the items from hoogle search results.
Tested only on Linux.
Installation
Using vim-plug
Plug 'junegunn/fzf', {'dir': '~/.fzf', 'do': './install --all'}
Plug 'monkoose/fzf-hoogle.vim'
Or use any other plugin manager. I bet you know it better than I'm.
Usage
:Hoogle or append it with initial search like :Hoogle >>=.
To open fzf window in a new fullscreen tab just append command with exclamation mark :Hoogle!
If you don't know how to properly search with hoogle, then look at the hoogle documentation.
Inside fzf window
enter to start new search with the current query.
alt-s to open default browser with documentation. If it doesn't work (perhaps if you are on macOS), then
change g:hoogle_open_link option to open links with the CLI tool.
alt-x to copy type annotation into default register. Paste it just with p.
alt-c to copy import statement into default register.
Esc or ctrl-c to close fzf window.
You can open :Hoogle appended with a word under the cursor with this command. Use a key combination that
suitable for you. In my config it is <space>hh:
augroup HoogleMaps
autocmd!
autocmd FileType haskell nnoremap <buffer> <space>hh :Hoogle <C-r><C-w><CR>
augroup END
Or you can set it as keywordprg and open fzf-hoogle window with K:
augroup HoogleMaps
autocmd!
autocmd FileType haskell setlocal keywordprg=:Hoogle
augroup END
