devdocs.vim

This is a Vim plugin for devdocs, which is an awesome multiple API documentation service. You can open and search devdocs from Vim.

• Open and search devdocs using command :DevDocs or :DevDocsAll
• Relate filetype to specific documentation.
• Search word under the cursor.

Usage

• :DevDocs [query] : Search with query with filetype related documentation (query can be omitted)
• :DevDocsAll [query] : Search with query with all documentation (query can be omitted)

Customize

Mapping K to search under the word quickly

devdocs.vim doesn't overrides any mapping by default. You should define key mappings if you need.

If you always want to override K mapping,

nmap K <Plug>(devdocs-under-cursor)

If you want to override K mapping in specific filetypes,

augroup plugin-devdocs
  autocmd!
  autocmd FileType c,cpp,rust,haskell,python nmap <buffer>K <Plug>(devdocs-under-cursor)
augroup END

Above replaces K in C, C++, Rust, Haskell, and Python.

Open with specific documentation on specific filetype

You can customize relationship between Vim's filetype and documentation. Below is an example of customization.

let g:devdocs_filetype_map = {
    \   'ruby': 'rails',
    \   'javascript.jsx': 'react',
    \   'javascript.test': 'chai',
    \ }

With above configuration, :DevDocs blah searches Rails documentation on filetype ruby.

:DevDocsAll searches all documentation ignoring filetype relation and below configuration explicitly disables this feature.

let g:devdocs_filetype_map = { '*': '' }

Open local devdocs

You can easily host local devdocs. If your local devdocs is hosted at localhost:9292, devdocs.vim uses it by following configuration.

let g:devdocs_host = 'localhost:9292'

If you use http:// to host your DevDocs instance, please use g:devdocs_url variable to specify an http:// scheme.

let g:devdocs_url = 'http://localhost:9292'

Make a command for specific document

You can use devdocs#open_doc() function to make such a command.

Below is an example for :DevDocsReact command to open page with 'react' documentation

command! -nargs=* DevDocsReact call devdocs#open_doc(<q-args>, 'react')

You can execute as below,

:DevDocsReact
:DevDocsReact componentDidMount

Open in non-default browser

devdocs.vim opens URL with open-browser.vim at first. If it is not installed, it tries to open default browser. If you don't install open-browser.vim and want to use non-default browser, please use g:devdocs_open_cmd to specify what command should be used for opening a browser.

" Open devdocs.io in Safari on macOS
let g:devdocs_open_cmd = 'open -a Safari'

" Open devdocs.io in Firefox on Linux
let g:devdocs_open_cmd = 'firefox'
