Hi. I'm trying to build a new docutils tool for processing
RestructuredText. I'm trying to write a scanner:
class rst-scanner : common-scanner
{
rule pattern ( )
{
return "^\\w*\\.\\.\\w+(include|image|figure)::\w+(.*)" ;
}
}
The problem is that the 2nd parenthesized group identifies the filename;
the first one should be ignored, and there's no way to express that
nicely. I'm guessing that this hack might work:
class rst-scanner : common-scanner
{
rule pattern ( )
{
return "^\\w*\\.\\.\\w+include::\w+(.*)"
"^\\w*\\.\\.\\w+image::\w+(.*)"
"^\\w*\\.\\.\\w+figure::\w+(.*)"
;
}
}
But really, there ought to be a more general mechanism, shouldn't there?
