octave: disable octave-workspace crash file

Question

How can I disable Octave from creating an octave-workspace file within the working directory when it crashes?

I don't see any option to disable it in octave_core_file_options() . Is this possible? Maybe through a hack by automatically removing the file at termination? (the problem is .octaverc runs at start)

Answer 1

What you're looking for is crash_dumps_octave_core :

Query or set the internal variable that controls whether Octave tries to save all current variables to the file 'octave-workspace' if it crashes or receives a hangup, terminate or similar signal.

Just for completeness, the reason why this family of functions ( octave_core_file_limit , octave_core_file_name , and octave_core_file_options ) have "octave_core" on the name instead of "octave_workspace", is that on older releases the default name of the file was "octave-workspace".

How could you have found this yourself?

1. from your question, you already knew about octave_core_file_options . If you see the bottom of that function help text, you will find:

   See also: crash_dumps_octave_core, octave_core_file_name, octave_core_file_limit.

2. Take a look at the manual section about this function by calling doc octave_core

3. you can use the lookfor command to search functions:
