<div class="moz-cite-prefix"><font face="monospace">mainly there are
two permanent background tasks: structure browsing in sidekick

highlighting. Both depend on edit mode. You could quickly
check if they're slowing down jedit by changing the edit mode
to "text" (means: no highlighting, no strucure) by ohne of
them:<br>

<blockquote type="cite" cite="mid:rttude$mgs$1...@ci..."><font
face="monospace">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.

<font face="monospace"><br>
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.
<br>
</font>
<font face="monospace"><br>
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 ?
<br>
</font>
<font face="monospace"><br>
Is there a way to completely turn off syntax highlighting for a
buffer ? Or for a file's edit mode ?
<br>
</font>
<font face="monospace"><br>
Will turning off syntax highlighting ( I hope that is possible )
prevent JEdit from trying to parse the C++ constructs in the
file ?
<br>
</font>
<font face="monospace"><br>
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.
