Subject: [Caml-list] Cannot find Stream Parser Documentation
Date: Fri, 5 Apr 2002 13:58:18 -0500 [thread overview]
Message-ID: <200204051858.g35IwIm01495@demokrit.cas.mcmaster.ca> (raw)
Hi,
currently I am finally trying to port my stuff from OCaml-3.02
to OCaml-3.04, and I am having problems related with stream parsers:
I am using the stream error catcher
[< .... ?? HERE >]
--- the separator once was a single `?',
and had to be turned into `??' for OLabl, and now neither works!
ocamlc -I +labltk -pp camlp4o -c xmlParse.ml
File "xmlParse.ml", line 101, characters 6-7:
Parse error: '>]' expected after [stream_patt] (in [parser_case])
Preprocessing error
99 let pc c = parser n
100 [< ' x when x == c
101 ? (string_of_int n ^ ": pc '" ^ String.make 1 c ^ "'")
102 >] -> ();;
The documentation for stream parsers that had been in the
``Language extensions'' chapter of the OCaml manual
seems to have disappeared, too.
I looked for it in the camlp4 directory,
but that directory doesn't even contain a README.
In the OCaml distribution, camlp4 seems to come with no documentation
besides the manpage!
(And on the camlp4 web pages, I couldn't find anything related
to the implementation of streams.)
A related issue: Among about 50 modules, only one uses stream parsers.
But
ocamldep -pp camlp4o *.mli *.ml > .depend
takes much longer than without camlp4.
How can I tell ocamldep to use camlp4 only for this file?
The ocamldep chapter has only includes in its example Makefile:
# Dependencies
depend:
$(OCAMLDEP) $(INCLUDES) *.mli *.ml > .depend
Is there any trick that would force file-specific settings to ocamldep?
Many thanks in advance!
Wolfram
