[REBOL] Big parse rules
From: AJMartin:orcon at: 19-Jul-2003 20:15
Anyone know how to turn a parse rule into a function?
Here's my situation. I've got a pile of 'parse rules in my eText function
(I'm rewriting it to make it smaller, faster, and more versatile), and I
find I need some sort of function-like ability, to keep the rules for a
section together, apart from the rest, and able to be reused or nested.
Table_Printable^: exclude Printable charset #"|"
Table_Cell^: [copy Text any Table_Printable^ (insert tail Table_Row compose
[td (Text)])]
Table_Row^: [
(Table_Row: copy [])
#"|" some [Table_Cell^ #"|"] opt #"|" LWS? Line_End (
insert tail Table compose [tr [(Table_Row)]]
Table_Row: none
)
]
Table^: [
(Table: copy [])
some Table_Row^ (
Accrete [table [tbody [(Table)]]]
)
]
As can be seen, I'd really like to make "Table_" into a sort of object or
function, rather than "fake" it with the arrangement of names.
Any ideas?
