Files not getting loaded/run from in vim plugin

Question

I'm developing a vim plugin for a new (toy) language called statemachine as part of a bigger project.

I'm trying to get a valid compiler/makeprg loaded in for this file type and I have one defined in compiler/statemachine.vim

However, when I try to run :make or set makeprg? I get make and makeprg= respectively. I also cannot see echoms that I have defined inside compiler/statemachine.vim. So it seems that my code in the file compiler/statemachine.vim is not executing.

Specifically I'm attempting to get this registered with Syntastic as a valid syntax checker, and a pre-requisite for that is getting makeprg and errorformat set to valid values.

I am able to use an equalprg that I have set and can see echoms from syntax_checkers/statemachine/statemachine.vim, so I know that my plugin is being run in some capacity.

And the filetype is detected correctly: set filetype? yields filetype=statemachine

Directory layout of the plugin so far:

.
├── README.md
├── autoload
│   └── statemachine.vim
├── compiler
│   └── statemachine.vim
├── complete.sh
├── example.sm
├── formatter.sh
├── ftdetect
│   └── statemachine.vim
├── ftplugin
│   └── statemachine.vim
├── syntax
│   └── statemachine.vim
├── syntax_checkers
│   └── statemachine
│       └── statemachine.vim
├── test.txt
└── validator.sh

Relevant parts of the vim plugin code:

// autoload/statemachine.vim
function! statemachine#Errorformat()
    return '%f:%l:\ %m'
endfunction

//ftdetect/statemachine.vim
au BufNewFile,BufRead *.sm set filetype=statemachine

// syntax_checkers/statemachine/statemachine.vim
function! SyntaxCheckers_statemachine_statemachine_GetLocList() dict
    let l:makeprg = self.makeprgBuild({'args': ''})
    echom 'inside getloclist'
    return SyntasticMake({'makeprg': l:makeprg,
                        \ 'errorformat': statemachine#errorformat() })
endfunction

call g:SyntasticRegistry.CreateAndRegisterChecker({'filetype': 'statemachine',
                                                \'name': 'statemachine'})

Why do you expect compiler/statemachine.vim to be sourced automatically? On an unrelated side note: you don't need to escape the space in errorformat. — Sato Katsura

@SatoKatsura Is that not how it works? I see this pattern referenced in multiple other plugins online and none of them manually call compiler/<filetype>.vim, so I assumed it was automatic similar to syntax/<filetype>.vim etc. — ScottO

You probably need to call compiler statemachine somewhere. — FDinoff

As @FDinoff points out, you probably need to add compiler statemachine to your ftplugin. — Sato Katsura

thanks, that did it. If one of you puts that as an answer I can accept it. — ScottO

Thanks to Sato Katsura and FDinoff in the comments of my original question, I simply needed to add compiler statemachine somewhere. I chose to add it in ftplugin.
