[jed-users] A couple of questions about the new_process() function

[Morten Bo Johansen <mbj@xxxxxxxxx>]

Hi

Hopefully everybody is still alive ;)

If I use the new_process() function to run some command, I may
catch its exit status by appending a ".wait() to the command,
e.g.

  variable obj = new_process([cmd], write=1).wait()
  
returns the following fields

  pid
  exited
  exit_status
  signal
  coredump
  stopped
  continued

but not the object field, fp1

If I do

  variable obj = new_process([cmd], write=1);
  obj.wait();
  
I get the fp1 object field but not e.g. the exit_status field.

What wait method shall I specifiy in order to get both?

Second question: Can new_process() act as a replacement for the
open_process() function?

With the open_process() function, I can start a persistent
process and attach it to a buffer and then communicate with it
and capture the output without having to start and stop the
process every time. I would like to perhaps simplify and maybe
also "robustify" the flyspelling function in my aspell.sl
extension, but I can't seem to figure out how to do it. The
documentation for new_process() does not cite any examples for
using it as a replacement for open_process(). The command I use
with the open_process() function is (as an example)

  variable pid = open_process ("aspell", "-d", "en", "-a", 3);

I may tie this process to a buffer and then send a word to it
and capture aspell's response as to whether the word was
misspelled or not.

Can I do something similar with new_process()?

Regards,
Morten
