Wikipedia:WikiProject C/C++/Syntax highlighting
It would be nice to make full use of HTML's facility with text formatting in code samples. Following are proposals for syntax highlighting.
Standard colors
While the usual white or off-white background is reasonably well suited for plain encyclopedic text, it's poor at providing the contrast needed to easily distinguish color. Thus, colored text should preferably be placed on a dark background to allow a broad range of colors to be used. Note, however, that pure blue is less visible against black than against white.
Code fragments should begin and end with {{begin code}} and {{end code}} to set the background color. The default colors are proposed to be as follows (it will of course be possible to override them with style sheets):
| Color | RGB triplet | Uses |
|---|---|---|
| White | #ffffff | keywords |
| Red | #ff0000 | decimal and octal numbers |
| Yellow | #ffff00 | characters, strings |
| Green | #00ff00 | preprocessor symbols |
| Cyan | #00ffff | function names |
| Blue | #0000ff | ? |
| Magenta | #ff00ff | hexadecimal numbers |
| Dark red | #a00000 | ? |
| Dark yellow | #a0a000 | comments |
| Dark green | #00a000 | ? |
| Dark cyan | #00a0a0 | punctuation |
| Dark blue | #0000a0 | ? |
| Dark magenta | #a000a0 | ? |
| Gray | #cccccc | everything else |
| Dark gray | #a0a0a0 | ? |
