syntax checker is not loading - please help

[Rick Veens]

Hi, 

I'm trying to write a synastic_checker for a language called ALF, the checker tool is named sweet.

I cannot get my checker to load. I did the following:

- Made the file sweet.vim in syntastic/syntax_checkers/alf/

- Added the following line to the default checkers syntastic/plugin/syntastic/registry.vim:

        \ 'alf':         ['sweet'],

I followed the example on the wiki (https://github.com/vim-syntastic/syntastic/wiki/Syntax-Checker-Guide)

:SyntasticInfo output:

Syntastic version: 3.8.0-38 (Vim 704, Linux, GUI)

Info for filetype: alf

Global mode: active

Filetype alf is active

The current file will be checked automatically

Available checkers: -

Currently enabled checkers: -

Press ENTER or type command to continue

Could anyone please give me a hand? I am new to this.

Best regards,

Rick Veens

P.S: The contents of my checker file are as follows:

if exists('g:loaded_syntastic_alf_sweet_checker')

    finish

endif

let g:loaded_syntastic_alf_sweet_checker = 1

let s:save_cpo = &cpo

set cpo&vim

function! SyntaxCheckers_alf_sweet_IsAvailable() dict

    if !exists('g:syntastic_alf_compiler')

        let g:syntastic_alf_compiler = executable(self.getExec())

    endif

    call self.log('g:syntastic_alf_compiler =', g:syntastic_alf_compiler)

    return executable(expand(g:syntastic_alf_compiler, 1))

endfunction

" function! SyntaxCheckers_ruby_mri_GetHighlightRegex(item)

"     if match(a:item['text'], 'assigned but unused variable') > -1

"         let term = split(a:item['text'], ' - ')[1]

"         return '\V\\<'.term.'\\>'

"     endif

"     return ''

" endfunction

function! SyntaxCheckers_alf_sweet_GetLocList() dict

    " let makeprg = self.makeprgBuild({

    "             \ 'args_after': '-i=' })

" let errorformat = '%EAt %l.%c-%l.%c:'

    return syntastic#c#GetLocList('alf', 'sweet', {

        \ 'errorformat':

        \     'At %l.%c-%l.%c:',

        \ 'main_flags': '-i=' . syntastic#util#DevNull() })

    " return SyntasticMake({ 'makeprg': makeprg, 'errorformat': errorformat})

endfunction

call g:SyntasticRegistry.CreateAndRegisterChecker({

            \ 'filetype': 'alf',

            \ 'name': 'sweet' })

let &cpo = s:save_cpo

unlet s:save_cpo

" vim: set sw=4 sts=4 et fdm=marker:

I seem to have made an error here:

function! SyntaxCheckers_alf_sweet_IsAvailable() dict
    if !exists('g:syntastic_alf_compiler')
        let g:syntastic_alf_compiler = executable(self.getExec())
    endif
    call self.log('g:syntastic_alf_compiler =', g:syntastic_alf_compiler)
    return executable(expand(g:syntastic_alf_compiler, 1))
endfunction

Where

let g:syntastic_alf_compiler = executable(self.getExec()) 

Had to be

let g:syntastic_alf_compiler = self.getExec()

I don't know why. I am new to vimscript. Maybe this can help someone in the future.
