preparing colored text

preparing colored text

[Jonathan Epstein]

I've read a lot about faces over the years, but there's something that
I just don't get: how do I prepare some text which is colored in a
specific way?

E.g., suppose I have the following text in my Emacs buffer (say, the
*Scratch* buffer):
  Here is some sample text colored in different ways

How can I make "Here is" red, "some sample" blue, "text" green,
"colored in" red, and "different ways" blue ?

The specific colors aren't important; an example using commonly
available faces such as:
font-lock-comment-face
font-lock-keyword-face
font-lock-warning-face

would be fine too.

Oh, I'm sort of wedded to Emacs 20 (I use 20.6.1), if there's an Emacs
20-compatible solution, that would be great.  Solutions that only work
on MS Windows would be OK too, although not optimal.

TIA,

Jonathan

Do you mean you want a mode where all occurrences of the word frumple
are in a specific color, or do you want something where you can point
at a word and say "make this blue"?

If the latter, investigate M-x enriched-mode RET.  And the M-g key.

If your version of emacs has it, you should probably try enriched-mode.

M-x enriched mode

Then select the text you want to be red.

Then from the menu go in Edit -> Text Properties -> Foreground Color

and enter red.

Repeat for all other colors.


Hope that helps,

Take a look at 
  http://www.emacswiki.org/cgi-bin/wiki.pl?CategoryFaces

enriched-mode has been mentioned, but maybe you want something like

Thanks for all the responses ... sorry if I was unclear.  I meant
doing this under program control.  Here's what I came up with
(copy-hack from faces.el) ... thanks again.

Jonathan


 (with-output-to-temp-buffer "*ColorExample*"
      (save-excursion
	(set-buffer standard-output)
	(setq truncate-lines t)
	(insert "here is some sample red text, green text, and flowery blue
prose")
	(put-text-property 20 29 'face 'font-lock-warning-face)
	(put-text-property 31 42 'face 'font-lock-type-face)
	(put-text-property 47 65 'face 'font-lock-function-name-face)
	))

(insert (propertize "warning" 'face 'font-lock-warning-face))

... easier to maintain in case the strings change :-)

Kai, this was my first attempt also. I copied this example into
*scratch* and evaluated it, it appears to just insert "warning"
without changing any text properties.

I ran M-: (get-text-property (point) 'face) with the point on the
inserted warning text. That expression returns nil. I'm confused
(like always)...

BTW, where'd you find Oort 0.18? :D

Probably you have font-lock turned on. It removes all "foreign" text
properties. Try it in a buffer without font-lock, for example in
text-mode.

In CVS Emacs you can use something like this

(insert (propertize "lirum larum" 'font-lock-face
		    'font-lock-warning-face))

even in buffers with font-lock.

Did you disable font-lock-mode in *scratch* before trying it out?

It's the CVS version.
