job_start callback : retrieve calling object funcref

Ni Va

I'm writing some little script to start jobs from serial or parallel way.

In the case of serial job's starts, I need to increment job current index each time the current job is finished.

The index is in the caller object (dict and funcref mechanism).

From the callback func, how can I retrieve ref of my main object caller to increment this index ?

Thank you

Sumup of code :

________ dict object ref

let s:ijob=0
let cmdlauncher = {}

function! cmdlauncher#new()  "{{{

        let obj = {}
        let obj._cmds = []      " Job command
        let obj._jobs = []      " Job object
        let obj._ijob = s:ijob  " Job index

        function! obj.add_cmd(cmd)   "{{{
                call add(self._cmds, a:cmd)
        endfunction "}}}
        function! obj.startjob() "{{{
                        let cmd = 'cmd /k '.self._cmds[self._ijob]

                        call add (self._jobs, job_start(cmd, {
                                                \ 'exit_cb'  : 'cmdlauncher#exit_cb',
                                                \ 'close_cb' : 'cmdlauncher#close_cb',
                                                \ 'callback' : 'cmdlauncher#callback'
                                                \ })
                        let ch = job_getchannel(self._jobs[-1])

        endfunction "}}}

        return obj
endfunction "}}}

function! cmdlauncher#exit_cb(job, status) "{{{
                echomsg "job exit with : ".string(a:job.' '.a:status)
                " echomsg  get("cmdlauncher", "name") "<< KO
        catch E716
                " No-op if data isn't ready
endfunction "}}}

________ caller

        " plan cmds
        let x = cmdlauncher#new()

        call x.add_cmd(cmd1)
        call x.add_cmd(cmd2)

        call x.startjob()
