Various fixes and improvements

[tomers]

Give some love to this nice tool. I would like to do some changes in it, so I go over the code first, and fix what I think should be fixed. I would be grateful in the maintainer of this tool would accept these changes.

Hi @tomers, thanks so much for the excellent cleanup!!!

I have a single request regarding your changes. I don't like adding the entire matplotlib as a dependency just so that we can discover fonts. I created a branch called vendor-matplotlib. If you merge that branch into here, then you should be able to remove the matplotlib dependency and access findSystemFonts with

from dymoprint._vendor.matplotlib.font_manager import findSystemFonts

Just wanted to extend the gratitude for this work you're putting into this code. Certainly I'm not qualified to do any of this.

I wouldn't mind a limited selection of system fonts, it may become overwhelming if it's too many, and I assume that instant preview of fonts like in LibreOffice may be too much to ask for.

Let's add it as-is, with all the fonts. I find the overwhelming amount to be preferrable over having missing a desired font. I definitely would like to add a preview to all fonts, but not in this iteration.

@maresb, @tomek-szczesny , can you please merge this now? I would like to keep working on this, but there's too many changes in this PR now...

I'm really excited about the live updating of the button when the device is ready or not.

Feel free to limit scope on this PR, this is already quite a lot!

I tried running it, but I'm getting the following error message, apparently due to inconsistency between Path and str types.

Traceback (most recent call last):

In order to get this traceback I had to modify https://github.com/computerlyrik/dymoprint/blob/caf47b19732e7bdf8118941f1eebd083f3b3fd62/src/dymoprint/q_dymo_label_widgets.py#L155 and replace err → traceback.format_exc(). (Also import traceback goes up top.) There are three other instances in this file which should probably be updated accordingly.

We could already start merging this in pieces. If I merge the vendoring stuff, then if you rebase it'll trim down quite a bit on the massive number of files modified.

[tomers]

Thanks @maresb for this quick and useful feedback. I've fixed all the issues you've reported.

[maresb]

Looks like you got it @tomers, it's running for me! And I see loads of fonts.

I'm on the train at the moment, so I can't test printing myself. @tomek-szczesny, is this something you could try out? If it works for you too, then I'll cut a release.

[maresb]

@tomers, would you be willing to write the release notes for this?

[tomers]

@maresb where can I write the release notes? I didn't notice any RELEASES file

[tomers]

Release notes:

What's Changed

- Use installed system fonts
- Development improvements:
  - It is now possible to develop with Dev Container in VS Code
  - `gui_dev.sh` script to aid developers iterating on the GUI application
- Print button is now available only when the printer is ready. Otherwise the cause of error is showing.
- Some internal code refactoring and cleanups

[tomek-szczesny]

I'm sorry I can't do any testing in next 48h either :(

[maresb]

Perfect @tomers , there is no file in the repo, but I will paste that into the GitHub release notes

[maresb]

Let's merge for now but delay the release until someone else tests with a device.
