Hi,
I'm trying to use instaparse to differentiate between identifiers and
keywords.
The following code is from the tutorial.
(def unambiguous-tokenizer
(insta/parser
"sentence = token (<whitespace> token)*
<token> = keyword | !keyword identifier
whitespace = #'\\s+'
identifier = #'[a-zA-Z]+'
keyword = 'cond' | 'defn'"))
The above parser works fine for:
(insta/parse unambiguous-tokenizer "cond id defn")
It recognizes cond and defn as keywords and id as identifier.
But if an identifier starts with a keyword such as condid:
(insta/parse unambiguous-tokenizer "condid id defn")
It doesn't work anymore. (I want it to recognize condid as an identifier
not a misspelled keyword)
Does anybody know how to make that work?
Thanks
