[ jEdit-users ] Turning off syntax highlighting for a file

[Edward D. <eld...@tr...>]

JEdit sometimes slows to a crawl when editing certain complicated C++ 
files. By complicated I mean a C++ file which shows advanced C++ syntax 
features and which also may have temporarily incorrect C++ syntax as I 
work through some programming problem. By slowing to a crawl I mean that 
moving my cursor around in the file or placing my cursor somewhere in 
the file or scrolling through the file, is sometimes extremely slow, 
without JEdit taking a number of seconds, sometimes 5 or more, before I 
can continue editing.

I believe this is happening because JEdit is trying in the background to 
parse the C++ constructs in the file, most probably because JEdit needs 
to understand the constructs in the file in order to do its syntax 
highlighting.

I would like to defeat this occasional slowness somehow and the thought 
that I have is to do whatever is necessary to stop JEdit from parsing 
the C++ syntax elements in the file.

Is Jedit parsing the C++ files in the background in order to understand 
its constructs ?

Is Jedit trying to understand the constructs in order to provide syntax 
highlighting ?

Is there a way to completely turn off syntax highlighting for a buffer ? 
Or for a file's edit mode ?

Will turning off syntax highlighting ( I hope that is possible ) prevent 
JEdit from trying to parse the C++ constructs in the file ?

The slowdown of course can be the result of some Plugin I have, but I do 
not see that any of my Plugins needs to parse the file for C++ 
constructs for any reason.
