Hi all,
I'm trying to write a a cp4 extension that evals and use a
parsed value during the parsing process... in symbols my problem
looks like :
let h = Hashtbl.create 10
let store l = Hashtbl.add h l
expr:
[
[ "keyword"; e = expr ->
let e' = EVAL_MAGIC_FUNCTION e in
let _ = store e' in
<:expr<other_function $e$>>
]
]
I don't want to write something like "["; e = LIST1 int SEP ";"; "]"
because I want to maintain the flexibility to accept a function or a
LIDENT instead that hard wired a list definition...
what's the magic function that gives me back an expression that I can
use in the extension context ? Does this function exist or I'm mixing
everything again ?
tnx,
p
