Random syntax parsing errors when opening scripts #14

Closed AVHon closed 2 years ago

AVHon commented 6 years ago

Sometimes, when I open a script, an error message pops up. This only happens some times when I open a sript. I have not been able to find any pattern. If I open and close the same file several times, some times I will get an error, and some times I won't.

Here is an example from opening a Python script:

Exception in thread "Thread-5" java.lang.Error: Error: could not match input

Here is another example from opening an IJ1 macro:

Here is another example, form opening the same IJ1 macro. (exactly the same)

Exception in thread "Thread-9" java.lang.Error: Error: could not match input

Most of the time, these errors don't seem to represent any actual problem -- the only unexpected behavior is that an error popped up. Sometimes, however, the syntax parser actually fails. For me, this always manifests itself in the same way: starting from some line in the middle of the file, every line below it is highlighted as a comment. I can fix this by going to the last line that isn't highlighted as a comment, commenting it out, and then uncommenting it. This always corrects the syntax highlighting for the rest of the file.

This seems to be fixed now (or at least there is a workaround)
