Hi Folks.
I am writting a Parser Grammar in the XTreams package http://squeaksource.com/@BPfsPY0nJbH9IXBW/wqWrIinC
to handle the Wikimedia wikitext https://en.wikipedia.org/wiki/Help:Wikitext#Text_formatting
My grammar looks like this so far:
'Body <- ( Template / Flow )*
LineCharacter <- [^\n]
Flow <- Bold / Italic / BoldItalic/ LinkShort / LinkFull / LineCharacter /Template
Italic <- "''''" Flow{"''''"}
Bold <- "''''''" Flow{"''''''"}
BoldItalic <- "''''''''''''" Flow{"''''''''''''"}
LinkShort <- "[" .{&[>]]} "]"
LinkFull <- "[" Flow{">"} .{"]"}
Whitespace <- [\s\t\n\r]*
Template <- "{{" Template "}}" / "{{" Flow{"}}"}
Heading4 <- Whitespace "==== " Flow{" ====\n"}
'
Italic and Bold work just peachy.
Template works for a simple Templates like:
{{reflist}}.
My Actor callback, for now just wraps it in a span like this:
<span style="text-decoration: underline">reflist</span>
Where things go south is when Templates are nested, for example on Infoboxes which are widely used in wiki markup:
Here is a truncated version of my output:
<span style="text-decoration: underline">Infobox Italian comune <---This is where the PEGActor callback started to wrap the outmost template.
| name = Elmas
| official_name = Comune di Elmas
.... | area_code = 070
| website = {{official website|http://www.comune.elmas.ca.it/</span> <--here is the nested Template. As you can see the Grammar ended the outermost <span></span> here and never recursed on the inner template.
| footnotes =
}} <---here is the outermost template should end.
So...I need a rule that will cover this.
Template <- "{{" Template "}}" / "{{" Flow{"}}"}
should be what?
Thank you for your help. t
