Epsilon does syntax-based highlighting for many different
programming languages. Set the buffer-specific variable
want-code-coloring to 0 to disable this feature or run the
change-code-coloring command. To change the colors Epsilon
uses, see the previous section. (Because certain modes like Perl and
HTML use coloring to quickly parse language syntax, if you don't want
to see the coloring it's often better to change the color selections
so they're identical instead of disabling code coloring entirely.)
If you use a very old and slow computer, you may need to tell Epsilon
to do less code coloring, in order to get acceptable response time.
Set the variable minimal-coloring to
1 to tell Epsilon to
look only for comments, preprocessor lines, strings, and character
constants when coloring. Epsilon will color all identifiers,
functions, keywords, numbers and punctuation the same, using the
c-ident color class for all. This makes code coloring much
When Epsilon begins coloring in the middle of a buffer, it has to
determine whether it's inside a comment by searching back for comment
characters. If you edit extremely large C files with few block
comments, you can speed up Epsilon by telling it not to search so
far. Set the variable color-look-back to the number of
characters Epsilon should search through before giving up. Any block
comments larger than this value may not be colored correctly. A
value of zero (the default) lets Epsilon search as far as it needs to,
and correctly colors comments of any size.
When Epsilon isn't busy acting on your keystrokes, it looks through
the current buffer and assigns colors to the individual regions of
text, so that Epsilon responds faster as you scroll through the
buffer. For smoother performance, Epsilon doesn't begin to do this
until it's been idle for a certain period of time, contained in the
idle-coloring-delay variable. This holds the number of
hundredths of a second to wait before computing more coloring
information. By default, it's
100, so Epsilon waits one second.
Set it to
-1 to disable background code coloring.
Normally Epsilon colors buffers as needed. You can set Epsilon to
instead color the entire buffer the first time it's displayed. Set
the variable color-whole-buffer to the size of the largest
buffer you want Epsilon to entirely color at once.
