Subject: ocamllex and yyless, putting back chars in lexbuf
Date: Thu, 12 Nov 2009 10:47:41 -0800	[thread overview]
Message-ID: <c55bbbbc0911121047w74b91d24g3db030a4884bebed@mail.gmail.com> (raw)

Hi,

Is there a way in ocamllex to put back certain characters
in the buffer. In flex you can do that

<LOOKING_FOR_XXX>[a-z]+ {
	yy_pop_state();
	yy_push_state(ST_TOP);
	return T_STRING_VARNAME;
}


<LOOKING_FOR_XXX>{ANY_CHAR} {
	yyless(0);
	yy_pop_state();
	yy_push_state(ST_TOP);
}


Should I play with fields like lexbuf_lex_curr_pos ?
