Vim wrapper for ShellCheck, a static analysis tool for shell scripts.

Commands

These commands are available in buffers with 'filetype' of sh.

:[range]ShellCheck[!] [args]

Run shellcheck for the current buffer using optional [args] and send any errors to the quickfix-window. Specify a [range] or use a visual selection to check only those lines, otherwise the entire buffer is checked. Call with a bang to automatically open the quickfix-window when errors are found.

:[range]LShellCheck[!] [args]

Run shellcheck for the current buffer using optional [args] and send any errors to a location-list-window. Specify a [range] or use a visual selection to check only those lines, otherwise the entire buffer is checked. Call with a bang to automatically open the location-list-window when errors are found.

QF Mappings

Open ShellCheck error definition on GitHub - gb

The gb command can be used quickfix or location list windows to open the ShellCheck error definition on GitHub. This functionality is enabled when the window’s w:quickfix_title attribute starts with one of the following:

  • :shellcheck – created by compiler shellcheck | :make or some other program
  • :ShellCheck – created by the :ShellCheck command
  • :LShellCheck – created by the :LShellCheck command

To disable this mapping:

let g:shellcheck_disable_mappings = 1

To setup a different map:

let g:shellcheck_disable_mappings = 1
autocmd FileType qf nmap <buffer> <silent> gB <Plug>(shellcheck-gb)

Note: The gb map will not be defined if one already exists.

Compiler

A ShellCheck :compiler is provided for use as a 'makeprg':

:compiler shellcheck
:make!

Configuration

g:shellcheck_qf_open

Specifies how the quickfix-window is opened when :ShellCheck! is used. The default value is "botright copen 10".

g:shellcheck_ll_open

Specifies how the location-list-window is opened when :LShellCheck! is used. The default value is "lopen 10".
