vim-so

vim-so wraps the so executable to provide a plain-language search interface for code snippets on Stack Overflow.

Example

Assume that you're building a Go application, and have forgotten how to reverse an array. You may run the following ex command:

:So reverse an array

The following will occur:

vim-so will detect the current filetype
vim will execute the following shell command: so -t go "reverse an array"
The first applicable code snippet will be pasted into the current buffer
You may cycle among snippets via so#next() and so#prev()

Installation

vim-so can be installed as described in :help packages, or by using a package manager like Pathogen, Vundle, or Plug.

Functions

so#search

Search the Stack Overflow API for code snippets matching a phrase. It's recommended that you map this function to a convenient command:

command -nargs=1 So call so#search(<q-args>)

so#next

Cycle to the next code snippet. It's recommended that you map this function to a convenient hotkey:

nnoremap <C-N> :call so#next()<CR>

so#prev

Cycle to the previous code snippet. It's recommended that you map this function to a convenient hotkey:

nnoremap <C-P> :call so#prev()<CR>

so#view

Open the Stack Overflow thread associated with the current code snippet in your web browser:

command SoView :call so#view()

Options

g:so_browser

The browser executable that should be used in conjunction with the so#view function.

Configuring

Here's a practical configuration example. Add these lines to your .vimrc:

let g:so_browser = "firefox"
command -nargs=1 So call so#search(<q-args>)
command SoView call so#view()
nnoremap <C-N> :call so#next()<CR>
nnoremap <C-P> :call so#prev()<CR>
