[[BR]] [[BR]] See TracSyntaxColoring for information about which languages are supported and how to enable support for more languages. || 166 166 |||| || 167 168 Since 1.1.2 the default, coding highlighting and MIME-type processors support the argument `lineno` for adding line numbering to the code block. When a value is specified, as in `lineno=3`, the numbering will start at the specified value. When used in combination with the `lineno` argument, the `marks` argument is also supported for highlighting lines. A single line number, set of line numbers and range of line numbers are allowed. For example, `marks=3`, `marks=3-6`, `marks=3,5,7` and `marks=3-5,7` are all allowed. The specified values are relative to the numbered lines, so if `lineno=2` is specified to start the line numbering at 2, `marks=2` will result in the first line being highlighted. 167 169 168 170 Using the MIME type as processor, it is possible to syntax-highlight the same languages that are supported when browsing source code. … … 229 231 }}} 230 232 233 Line numbers can be added to code blocks and lines can be highlighted //(since 1.1.2)//. 234 {{{ 235 {{{#!python lineno=3 marks=3,9-10,16 236 def expand_markup(stream, ctxt=None): 237 """A Genshi stream filter for expanding `genshi.Markup` events. 238 239 Note: Expansion may not be possible if the fragment is badly 240 formed, or partial. 241 """ 242 for event in stream: 243 if isinstance(event[1], Markup): 244 try: 245 for subevent in HTML(event[1]): 246 yield subevent 247 except ParseError: 248 yield event 249 else: 250 yield event 251 }}} 252 }}} 253 {{{#!python lineno=3 marks=3,9-10,16 254 def expand_markup(stream, ctxt=None): 255 """A Genshi stream filter for expanding `genshi.Markup` events. 256 257 Note: Expansion may not be possible if the fragment is badly 258 formed, or partial. 259 """ 260 for event in stream: 261 if isinstance(event[1], Markup): 262 try: 263 for subevent in HTML(event[1]): 264 yield subevent 265 except ParseError: 266 yield event 267 else: 268 yield event 269 }}} 270 231 271 For more processor macros developed and/or contributed by users, visit the [https://trac-hacks.org Trac Hacks] community site. 232 272
