Before:
Save g:ale_command_wrapper
let g:ale_command_wrapper = ''
function! TestCommand(expected_part, input) abort
let l:expected = has('win32')
\ ? 'cmd /s/c "' . a:expected_part . '"'
\ : split(&shell) + split(&shellcmdflag) + [a:expected_part]
AssertEqual l:expected, ale#job#PrepareCommand(bufnr(''), a:input)
endfunction
After:
Restore
unlet! b:ale_command_wrapper
delfunction TestCommand
Execute(The command wrapper should work with a nice command):
let b:ale_command_wrapper = 'nice -n 5'
call TestCommand('nice -n 5 foo bar', 'foo bar')
Execute(The command wrapper should work with a nice command with an explicit marker):
let b:ale_command_wrapper = 'nice -n 5 %*'
call TestCommand('nice -n 5 foo bar', 'foo bar')
Execute(Wrappers with spread arguments in the middle should be supported):
let b:ale_command_wrapper = 'wrap %* --'
call TestCommand('wrap foo bar --', 'foo bar')
Execute(Wrappers with the command as one argument should be supported):
let b:ale_command_wrapper = 'wrap -c %@ -x'
call TestCommand('wrap -c ' . ale#Escape('foo bar') . ' -x', 'foo bar')
Execute(&& and ; should be moved to the front):
let b:ale_command_wrapper = 'wrap -c %@ -x'
call TestCommand('foo && bar; wrap -c ' . ale#Escape('baz') . ' -x', 'foo && bar;baz')
let b:ale_command_wrapper = 'nice -n 5'
call TestCommand('foo && bar; nice -n 5 baz -z', 'foo && bar;baz -z')
