[Newbie] Colorizing keywords

[Newbie] Colorizing keywords

[Robert Pollard]

Hello all,

Is there a way to define the colors that are used for keywords in a 
document?  For example, if I am editing an HTML document I want the 
keywords colorized instead of just plain black and white.  I know there 
is an HTML mode but it doesn't colorize anything.  Can I change the 
colors to indicate what colors I want if there is a predefined color 
scheme for a particular mode?

If there is a way to turn on colorization in HTML mode I would 
appreciate someone letting me know how this works.

I am working in Cygwin and Emacs version 21.2.1.

Thanks in advance for any time you use to help me with,

You just need to turn it on.

There is a check box in the Options menu called "Syntax Highlighting",
which should do the trick. Or you can put "(global-font-lock-mode 1)"
into your .emacs.

There is a detailed description in the FAQ (Help->Faq, then type "i"
(for index) and "syntax" and you should find it). 

Cheers

Phil

Do you know about font-lock-mode? C-h a font-lock shows you. You may
also be interested in color-theme, which lets you easily customize
which colors are used.

Yes I now know about font-lock thanks to you and Phillip Lord.  This 
takes care of known document types.  What about making my own 
definitions for colorization?  Is it possible to create my own database 
of keywords and define the color that is used for each?  How does 
font-lock-mode do it?  It would have to have a place where the keywords 
and patterns are defined with what colors they should be.  Where would 
this be located so I can figure out how to do my own definitions?  I 
suspect there is Lisp code involved and I can sort of imagine the Lisp 
code that could do what is needed.

Any ideas?

Thanks,

Robert

Read the fine manual:

,----[ (info "(emacs)Font Lock") ]
|    Font Lock highlighting patterns already exist for many modes, but you
| may want to fontify additional patterns.  You can use the function
| `font-lock-add-keywords', to add your own highlighting patterns for a
| particular mode.  For example, to highlight `FIXME:' words in C
| comments, use this:
| 
|      (font-lock-add-keywords
|       'c-mode
|       '(("\\<\\(FIXME\\):" 1 font-lock-warning-face t)))
| 
|    To remove keywords from the font-lock highlighting patterns, use the
| function `font-lock-remove-keywords'.
