Any updates on this fix? Working on code with 8000 lines with numerous comments that don’t close with --]], only ]] makes 8000 lines of code one colour… Not too handy :(. Close to bailing and going to Sublime, and I’d rather not.
PS: Search and replacing ]] for --]] was disastrous since there were multiple tables like [[I]] - which fell over miserably 
Hi Graham
Sorry I didn’t get to it yet… but here is a quick fix:
Run this command in the terminal:
sed -i -e 's/--]]/]]/g' /Applications/Xcode.app/Contents/SharedFrameworks/DVTFoundation.framework/Versions/A/Resources/Corona.xclangspec
After running the command you need to restart Xcode.
Thanks.
Ahh… bliss… that’ll do for now :). Thanks
When using block Editor/Structure/Toggle comments I’m getting // as comments instead of --. Any advice?
Another thing that I encountered is that Corona api lookup always invokes Safari instead of my default Chrome browser. Otherwise Xcode invokes default browser but not in the case of Corona api lookup.
I am afraid that it isn’t possible to change the toggle comment characters. I didn’t find a way to do it and I see that it doesn’t work for other Xcode supported languages like python, html, and applescript either… so I am pretty sure it is not possible.
Yes I changed it to always use Safari some time ago because of a bug in MacOS 10.12.5.
I think apple fixed the bug in 10.12.6 so if you are using that or later you can change it back like this:
Type in terminal:
open -a Xcode /Users/[your user]/Library/Developer/Xcode/UserData/Behaviors/doc-lookup.cfx.applescript
Now Xcode opens a script file. In that file locate this part:
tell application "Safari" open location docUrl activate end tell
and replace + save it with this:
open location docUrl
Now the docs should open in your default browser.
Thanks, Jacob
Thanks Jacob, your tip works great!
