Hi all,
According to Bram example in the job's help now,
Is it possible to pass additional parameters to job's handlers callback in
vim9script ?
Thank you
Nicolas
This minimalist example WORKING as Bram said:
def Compress_OnExit(job_id: job, exit_status: number): void
echom 'Job OnExit ' .. job_id->string() .. ' exited with status ' ..
exit_status
enddef
var job = job_start(cmd, { 'exit_cb': Compress_OnExit})
This minimal example with additional params:
def Compress_OnExit(job_id: job, exit_status: number, foo: string): void
echom 'Job OnExit ' .. job_id->string() .. ' exited with status ' ..
exit_status
# Compress_CopyToDrive('PATRIOT')
enddef
var job = job_start(cmd, { 'exit_cb': function('Compress_OnExit',
['foo']) } )
