Some code files just showing a grey screen

[kayserifserif]

Thanks for making this!

I just tried to install the extension and am only seeing a grey screen when I QuickLook some code files.

I'm not sure exactly which filetypes are working and which aren't – I tried a .zsh file and it was working.

I'm on macOS Monterey 12.5.1 and I installed the extension by running brew install --cask --no-quarantine syntax-highlight and opening the app (it didn't give me a warning). I've tried restarting and uninstalling/reinstalling. Any help appreciated! Thanks!

on the application enable the debug flag. Then try to open a quicklook preview. On your desktop will be created a console.log file. Inside there are some error messages?

Hi, sure, sorry about the long wait! I tried to preview a JSON file and got this log.

Sorry about the long wait! The log show this error: cat: /Users/katherine/Documents/cases-tool/package-lock.json: Operation not permitted.

• Do you grant the app to access to the Documents folder (also check on the System settings, privacy section, file access)?
• Does the file have read privilege?
• You can preview other source files inside the Documents folder? and also inside the the /Users/katherine/Documents/cases-tool folder?
• If you copy the package-lock.json in other folder outside the documents dir, can be previewed?

Hi 👋

Following a Dropbox update this morning (which moves the Dropbox folder to a more secure location ~/Library/CloudStorage/Dropbox) I found that I was experiencing this same issue.

So, following this comment I opened System Settings, Privacy & Security, Files and Folders, Syntax Highlight > (expand) A Dropbox option appears in the expander and shows a toggle, (which is off)

I toggled it on, and my expectation was that this was the fix! But the files within Dropbox are still displaying 'grey' in QuickLook. The same file in another location displays nicely.

MacBook Pro 2020 (M1 16GB) MacOS Ventura 13.0.1 Syntax Highlight 2.1.15 (64) Dropbox v161.4.4923
