Color syntax for Ruby breaks when %= is encountered

[ice7512]

Hey,

For some reason when Notepad++ sees %=, it can’t figureout how to highlight stuff properly (as seen below

How do I fix this?

Can you post the debug-info from the ? menu, the last menu item?
Which language do you use?

@Ekopalypse
I am using Ruby.

quick info before I have to go back to work.
Can confirm the behavior with my installation as well.
Will check later if there is something which can be done to solve it unless someone else already jumped in.

Seems to be a scintilla issue because the demo editor (SciTE)
is doing the same thing.

And after searching scintillas bug tracker I found this .
Not good news I’m afraid but please don’t shoot the messenger :-)

@Ekopalypse Is there anything I can locally do on my machine to prevent this from happening?

What you might try is to use something like this,
which means that you need to install the PythonScript plugin.
The limitation of this technique is that you can only define foreground colors,
and if you have really large source code files with lines > 10_000 and you fold a lot of code,
it will slow down your typing experience.

I use this every day with Python code, but my files usually don’t exceed 1_000 lines of code.

Other then that, you have to build npp and scintilla yourself and make the fixes in Ruby lexer.

As a longer term solution you can try to get the Scintilla people to have another look at it.
