3134 Normally, LaTeX keywords support 0-9, a-z, A-z, and 192-255 only. Latex | |
3135 keywords don't support the underscore - except when in *.sty files. The | |
3136 syntax highlighting script handles this with the following logic: | |
3137 | |
3138 * If g:tex_stylish exists and is 1 | |
3139 then the file will be treated as a "sty" file, so the "_" | |
3140 will be allowed as part of keywords | |
3141 (irregardless of g:tex_isk) | |
3142 * Else if the file's suffix is sty, cls, clo, dtx, or ltx, | |
3143 then the file will be treated as a "sty" file, so the "_" | |
3144 will be allowed as part of keywords | |
3145 (irregardless of g:tex_isk) | |
3146 | |
3147 * If g:tex_isk exists, then it will be used for the local 'iskeyword' | |
3148 * Else the local 'iskeyword' will be set to 48-57,a-z,A-Z,192-255 | |
