eval: Refactor vimscript job control API
- Remove JobActivity autocmd and v:job_data variable
- Simplify `jobstart` to receive:
- An argument vector
- An optional dictionary which may contain any of the current `jobstart`
options plus `on_stdout`, `on_stderr` and `on_exit` callbacks.
- Refactor and add more job tests
- Update documentation

2. Usage *job-control-usage*
|
||||
|
||||
Here's a quick one-liner that creates a job which invokes the "ls" shell
|
||||
command and prints the result:
|
||||
>
|
||||
call jobstart('', 'ls', ['-a'])|au JobActivity * echo v:job_data|au!
|
||||
JobActivity
|
||||
|
||||
In the one-liner above, creating the JobActivity event handler immediately
|
||||
after the call to jobstart() is not a race because the Nvim job system will
|
||||
not publish the job result (even though it may receive it) until evaluation of
|
||||
the chained user commands (`expr1|expr2|...|exprN`) has completed.
|
||||
|
||||
Job control is achieved by calling a combination of the |jobstart()|,
|
||||
|jobsend()| and |jobstop()| functions, and by listening to the |JobActivity|
|
||||
event. The best way to understand is with a complete example:
|
||||
|jobsend()| and |jobstop()| functions. Here's an example:
|
||||

|
||||
let job1 = jobstart('shell1', 'bash')
|
||||
let job2 = jobstart('shell2', 'bash', ['-c', 'for ((i = 0; i < 10; i++)); do echo hello $i!; sleep 1; done'])

- The second shell is started with the -c argument, causing it to execute a
|
||||
command then exit. In this case, the command is a for loop that will print 0
|
||||
through 9 then exit.
|
||||
- The `JobHandler()` function is called by the `JobActivity` autocommand (notice
|
||||
how the shell* pattern matches the names `shell1` and `shell2` passed to
|
||||
|jobstart()|), and it takes care of displaying stdout/stderr received from
|
||||
- The `JobHandler()` function is a callback passed to |jobstart()| to handle
|
||||
various job events. It takes care of displaying stdout/stderr received from
|
||||
the shells.
|
||||
- The v:job_data is an array set by the JobActivity event. It has the
|
||||
following elements:
|
||||
- The arguments passed to `JobHandler()` are:
|
||||
|
||||
0: The job id
|
||||
1: The kind of activity: one of "stdout", "stderr" or "exit"
|
||||
2: When "activity" is "stdout" or "stderr", this will contain a list of
|
||||
lines read from stdout or stderr
|
||||
1: If the event is "stdout" or "stderr", a list with lines read from the
|
||||
corresponding stream. For "exit", it is the status returned by the
|
||||
program.
|
||||
2: The event type, which is "stdout", "stderr" or "exit".
|
||||
|
||||
The options dictionary is passed as the "self" variable to the callback

function. Here's a more object-oriented version of the above:
