Extension .mjs is not recognized as javascript.

[Lonniebiz]

Geany 1.37.1
Debian 11

Please associate the extension .mjs with javascript. When I open a mjs file, that contains javascript, the syntax highlighting I expect doesn't occur.

Furthermore, I see no way, within Geany's settings to create this association for future times that I open a .mjs file.

Lastly, at the bottom of the screen, where is says "Filetype: None", clicking that doesn't allow you to manually set the file type. I find this fact very non-intuitive.

1. I changed line 44 of of filetype_extensions.conf to:
   Javascript=*.js;*.mjs;
2. Saved the file
3. Closed Geany
4. Re-Launched Geany
5. Opened a file with a .mjs file extension

Still, the .mjs file is not receiving Javascript highlighting. @elextr

Also uncomment the [section header] line above.

@elextr Thank you. That worked, but the purpose of my bug report remains; I hope Geany will add .mjs as a default extension, so other JS developers don't have to endure any inconvenience regarding .mjs files.

Additionally, when a user changes a Filetype, for an extension Geany doesn't recognize via Document > Set Filetype, a very nice automation would be for Geany to prompt the user: "Would you like Geany to always open .mjs files as the JavaScript filetype?"

Lastly, on the information bar, at the bottom of Geany, I find it very un-intitive that you cannot just click filetype: none as a shortcut for achieving the same thing that Document > Set Filetype achieves.

These enhancements are certainly not a necessity, but I know they'll be appreciated by newcomers.

I'm sure if "somebody"¹ made a pull request it wouldn't be a problem, so long as .mjs doesn't clash with anything else.

And any of the other enhancements could be accepted, but again "somebody" has to do it. Especially to explain how the "Would you like Geany to always open .mjs files as the JavaScript filetype?" would be extendable to anything else, having it hard coded seems weird if .mjs is in the filetype.extensions file.

1. somebody in quotes is a project idiom for "not necessarily you, but almost certainly not me" :-) ↩

I'm using a concrete example to explain an abstraction. I'm not suggesting to hard code .mjs specifically (other than I'm suggesting to make it a default).

Instead, I'm suggesting that any time a Geany user encounters "Filetype: None", that after they set that file type using Document > Set Filetype (for example), that Geany takes note of what ever that extension is, and asks the user "Would you always like to associate files with the extension ".???" with "the format you've just specified".

When a graphical user interface is complete, there's rarely a need to read a manual. If you want to do something to a thing, you right-click on that thing, and it shows you a list of "all you can do" with the thing that was right-clicked. You can intuitively discover anything you want to do and the application asks you if you want it to remember any preference the first time you do it. This is ideal, but I realize that is a whole lot of work to get it to that stage. I'm merely suggesting things that go that direction. @elextr

I'm not familiar with this code base, I'm not sure which file to modify to add .mjs as an extension for javascript.

Would it be line 144 here? :
https://github.com/geany/geany/blob/master/src/filetypes.c

Maybe you could add a line under that line that says:
FT_INIT( MJS, JAVASCRIPT, "Javascript", NULL, SOURCE_FILE, SCRIPT );

But, I can confirm this: people that use Node.js and ecmascript modules, must use the extension .mjs and not js for those modules. I call it Michael Jackson Script for fun, but here is the real reason:

This is an unhelpful comment; pointing to a sample tutorial would be better. The manual seems geared to help those already familiar with the system, and those already understanding the nuances between Filetype definitions, Custom filetypes, Special file.filetypes, and Filetype extensions.
I am currently trying to add .awk extension to look like .pl, and having problems. I've created entry [Extensions] + Awk=*.awk; in filetype_extensions.conf, created in ~/.config/geany/filedefs. Also a filetypes.awk there, copied from /usr/shared/geany/filedefs/filetypes.perl and changing perl & pl to awk but ... not working.

The system filetype_extensions.conf that you edited locally.

If someone wrote one they could put it on the wiki and post a link here.

I am currently trying to add .awk extension to look like .pl, and having problems. I've created entry [Extensions] + Awk=*.awk; in filetype_extensions.conf, created in ~/.config/geany/filedefs.

If you want awk to be treated like perl, can't you just add *.awk to the perl line?

Different extension, different keywords. I can change ~/.config/geany/filetype_extensions.conf line Perl=*.pl;*.perl;*.pm;*.agi;*.pod; to Perl=*.pl;*.perl;*.pm;*.agi;*.pod;*.awk; which formats as a perl file, which I suppose is a start. But why doesn't it work with:

• an alternative additional line of Awk=*.awk;
• together with a file ~/.config/geany/filetypes.awk that's cloned from /usr/shared/geany/filedefs/filetypes.perl with changes

Ok, fair enough, but since its nothing to do with the OP about .mjs please make another issue rather than hijacking this one.
