[Feature] Cura support

[varazir]

Please support: Cura
I know there are previous post about adding settings to your start/exit code.
It's it better to get it right with the correct regexp?

Sample gcode:
https://gist.github.com/varazir/4a290275cc2b8da43feea4a9ba982493

I'm trying to understand how the parser works, I used this site to test my regexp ( and get help) https://regex101.com

If I understand correct n\ is replaced with a New line before the file get parsed ?
If that is the case this should remove the ;SETTING_3 garbage and this should pick the correct values.

If it's not the case that \n get replaced before parsing this should get the correct values after this

I added this as well to get only the data that is needed.

Tested both but the SlicerSettingsTab can't find any settings.

;End of Gcode[\s\S]+
\n?;SETTING_3 
(?P<key>\w+) = (?P<val>[^\\]+)

@varazir: Please use the g-code script for Cura support located here. There are more details in the original issue (#1), but there are two core problems:

1. It only shows settings that were changed.
2. JSON cannot be parsed with regular expressions.

However, you are correct that \\n is equivalent to a newline in their format.
Also, SlicerSettingsTab just taps off of the settings parsed by this plugin.

If you do find a regex way to parse this, please let me know!

For now, I am closing this; feel free to follow up and/or reopen.

I don't want to add that amount of data in the exit/start code. If I reinstall Cura I nee dto remember to add it.
If you look at the regexp I posted I managed to extract the values from orginal Cura settings information.

@varazir: Relative to gcode, the script is tiny. However, I'll take a look at your regexes.

[tjjfvi]

@varazir: While it seems that, combined, your regexes would work, it currently only supports a single regex.

[varazir]

@tjjfvi ya need of 2 atleast. One to remove the \n?;SETTING_3 and second (?P\w+) = (?P[^\\]+) to get the data. The first one is just to lower the amout of data needed to process

[varazir]

@tjjfvi could you add support for more then one regexp ?

@varazir: I'm sorry, but I'm too busy with other projects right now, but if you submit a PR, I can merge & release it.
