[REBOL] Using 'to in parse dialect
From: hallvard::ystad::oops-as::no at: 5-May-2005 2:04
Hello folks
I have a parse problem again. Hope someone here can help (Brett?).
Heres an example from codeconscious.com:
ws: charset {^A^B^C^D^E^F^G^H^-^/^K^L^M^N^O^P^Q^R^S^T^U^V^W^X^Y^Z^[^\^]^!^_ ^~ }
input-string: "fox dog"
parse/all input-string [ [any ws "fox"] [any ws "dog"] ]
The last parse statement returns 'true. But now, what if we use the 'to:
input-string: "let's make a new speciaes: a fox dog"
parse/all input-string [ to [any ws "fox"] [any ws "fox"] [any ws "dog"] ]
** Script Error: Invalid argument: any ws fox
** Near: parse/all input-string [to [any ws "fox"] [any ws "fox"] [any ws "dog"]]
What did I do wrong?
It seems that 'to in the parse dialect is very restrictive as to what may follow. The
same applies to 'thru.
Please help me someone!
