A Vim plugin that completes words from the currently open web page in your browser.

Currently works with:

• Chrome on Mac OS.
• Qutebrowser on Linux and MacOS.
• Firefox in a fork.

With vim-plug:

Plug 'thalesmello/webcomplete.vim'

deoplete is an awesome asynchronous completion engine for Neovim. webcomplete works with deoplete out of the box. Just start typing to see suggestions of words comming from your browser.

• g:deoplete#sources#webcomplete#script: Execute this command-line string to get a list of words instead of default internal sh/webcomplete. You may add arguments to the string, e.g. cat /tmp/words.txt.

ncm2 is also supported. Once ncm2 is configured in your configuration files, the completions for webcomplete should be enabled by default.

• g:ncm2_webcomplete_script: Same as option for deoplete, but for ncm2.

coc is also supported. Once coc is configured in your configuration files, the completions for webcomplete should be enabled by default.

• g:coc_webcomplete_script: Same as option for deoplete, but for coc.

Vim allows you to define a completefunc or an omnifunc to give you completions during insert mode. webcomplete provides you with a function that you can plug into these built in features.

To set it up, use either of the two lines below:

" Use <C-X><C-U> in insert mode to get completions
set completefunc=webcomplete#complete

" Use <C-X><C-O> in insert mode to get completions
set omnifunc=webcomplete#complete

Currently this plugin only supports Google Chrome on Mac OS.

To use it, you must enable "Allow JavaScript from Apple Events" in View > Developer submenu.

Set one of the _webcomplete_script variables (described above) to $plugin_dir/sh/qutebrowser/webcomplete, where $plugin_dir is the location of this plugin.

Currently there is no official support for Firefox, but there is a fork with Firefox support

• Currently works on Mac OS because of the osascript command line utility, which is used to fetch text from the page
• Assumes you have only one browser window opened. If there is more than one window open, it picks the most recently used.
• Currently works only on Chrome, but it's possible to use with other browsers.

If you would like to contribute to the project by supporting your browser or operating system, I would be happy to accept pull requests.

The project was only possible with the help of Reddit user 18252 and by looking at tmux-complete.vim as reference when implementing this plugin.
