.gcode Generated by Prusa Slicer Not Recognized

[nverdonk]

Describe the bug
G-Code files produced by PrusaSlicer are not recognized or highlighted by extension. They are .gcode file extensions.

To Reproduce
Steps to reproduce the behavior:

1. Generate G-Code file using PrusaSlicer
2. Save file to Desktop
3. Open file in VS Code
4. Confirm file is not recognized as G-Code

Expected behavior
Expect the file type to be recognized and highlighted properly. VS code seems to recognize that it is a gcode language but extension does not (see screenshot below),

Screenshots

Environment / Version:

• OS Version: Windows 10
• VSCode Version: 1.55.2
• Extension Version: v0.5.1

Additional context
I might be missing a step in the process here as the extension is working properly if I make a blank .gcode file and type some commands in.
I have also copied all the text from the PrusaSlicer generated file and pasted into the user-made file and correct highlighting occurs

Let me know if this should be moved, tagged, or deleted.

@nverdonk can you attach the file here so I can try it on my computer with the current dev version?

[nverdonk]

@mikecentola Yes, here is a file to play around with. I just sliced it now and confirmed the same issue is occurring.

Had to ZIP it as GitHub won't allow native upload of .gcode
Drive Gear.zip

[mikecentola]

@nverdonk I'm on it!

Visual Studio Code does not colorise that big files...

You can enable it by clicking on "Forcefully Enable Features" or in settings – editor.largeFileOptimizations

[mikecentola]

@nverdonk yup @belkid is correct. I got the same error

[nverdonk]

Highlighting Fixed

Toggling editor.largeFileOptimizations corrected the highlighting issue, but the G-Code Tree from the extension still claimed to not recognize the G-Code file.

This time, however, a loading bar showed up; perhaps the file is too large for the tree as well?

[mikecentola]

@nverdonk Could be because the file is so large. Let me do some investigating on that side as well.

[nverdonk]

@mikecentola @BelKed Thank you for such quick responses and help!

@mikecentola I believe the file size is the issue with the tree. I deleted pretty much the whole file (~550,000 lines to 374 lines) and the tree loads correctly now.

The tree would be so cumbersome for a file of that size anyway; don't think this will ruin anyone's workflow :), just wanted to make sure it wasn't a bug.

[mikecentola]

No worries. I wonder if I should add a detection for large files to not even try if it's over a certain size.

[nverdonk]

I think adding note or warning along the lines of

This file exceeds maximum readable file size of _____ MB. VS Code might disable highlighting and GCODE tree will not generate

would help catch people in my situation in the future.

[mikecentola]

@nverdonk yeah for sure. I'll see if I can find somewhere to add it. I'm working on the hover code right now.

[mikecentola]

I added a warning popup for anything over 10K lines when autoRefresh is enabled.

[nverdonk]

I think that's a great addition and will save people a lot of headache in the future! I'll close out the issue for now and we can reopen if needed.
