I think we have enough existing bugs that are open on adding a feature to allow Octave to open a file in its editor and register that action with the OS desktop environment, closing as a duplicate.

That preference setting was added after 4.0, it will only appear in development versions and 4.2.

I think it's clear from the original comment what is being described is opening a file from the OS, not opening a file from within Octave's "File Browser" panel.

I figured that as well but "file explorer" is a bit ambiguous. At least it works in Octave's own file browser.

@OP / Jason:
Do you run the Octave GUI? if yes, click in the main menu on Edit, then Preferences, then File browser tab. The setting should be there.

I do not see the option "Extensions of files to be opened in the default text editor" in my preferences at all.

I think the OP is talking about the OS file browser.

This would require a couple of changes, probably need to be reported as separate bugs:

  • the ability to call Octave with a foo.m file name, possibly with some extra command-line option, and have that file be opened in the Octave editor
  • the ability to send Octave some kind of IPC signal to open a file name in the editor when Octave is already running
  • the (possibly optional) ability for Octave to know that an instance of Octave is already running, and send an IPC signal to the other instance of itself to open the file

I think users will want the ability to do both actions from the OS file browser, either run an m file as an executable script with Octave (calling Octave as an interpreter), or edit it with Octave's editor (calling Octave as an editor/IDE).

FWIW, in the mxe-octave binaries for windows it works OOTB the way you wish. Must be some default setting then.
In the Edit | Preferences pane => file browser tab, I do see ".m" listed in the "Extensions of files to be opened in the default text editor" setting. Can you check if that also set in your preferences?

Now that Octave opens a GUI I think that it would be preferable that the GUI persists after doubling clicking an m-file in the file explorer in Ubuntu (and other applicable systems). For me, and maybe others, when I double click an m-file I'm mostly interested in inspecting its text not executing the m-file.

Couple other notes of this unexpected behavior:


I think double clicking an m-file, when Octave is associated with that m-file by default by the operating system, the file should simply open the octave gui and display the file in the editor. If the user wants to execute the file they would use a gui button or matlab command.
