| 7 | 1 " Vim syntax file |
| 2 " Language: CWEB | |
| 3 " Maintainer: Andreas Scherer <andreas.scherer@pobox.com> | |
| 3237 | 4 " Last Change: 2011 Dec 25 by Thilo Six |
| 7 | 5 |
| 6 " Details of the CWEB language can be found in the article by Donald E. Knuth | |
| 7 " and Silvio Levy, "The CWEB System of Structured Documentation", included as | |
| 8 " file "cwebman.tex" in the standard CWEB distribution, available for | |
| 9 " anonymous ftp at ftp://labrea.stanford.edu/pub/cweb/. | |
| 10 | |
| 11 " TODO: Section names and C/C++ comments should be treated as TeX material. | |
| 12 " TODO: The current version switches syntax highlighting off for section | |
| 13 " TODO: names, and leaves C/C++ comments as such. (On the other hand, | |
| 14 " TODO: switching to TeX mode in C/C++ comments might be colour overkill.) | |

| 21 " For starters, read the TeX syntax; TeX syntax items are allowed at the top | |
| 22 " level in the CWEB syntax, e.g., in the preamble. In general, a CWEB source | |
| 23 " code can be seen as a normal TeX document with some C/C++ material | |
| 24 " interspersed in certain defined regions. | |
