[antlr-interest] Typo in comments in C runtime... and Where is mismatchRecover() ??

[Ruslan Zasukhin]

Hi Jim,

For your info:

FILE  antlr3baserecognizer.c
 

/// The exception that was passed in, in the java implementation is
/// sorted in the recognizer exception stack in the C version. To 'throw' it
we set the
/// error flag and rules cascade back when this is set.
///
static void *    
recoverFromMismatchedToken  (pANTLR3_BASE_RECOGNIZER recognizer,
ANTLR3_UINT32 ttype, pANTLR3_BITSET_LIST follow)



sorted in the recognizer
^^^^^^^^^^

I think should be stored ...



======================
Also functions match() and mismatch() have comments,
Where is said that 

override mismatchRecover() and have it call
/// plain mismatch(), which does not recover

But Greep search over ANTLR 3.4 sources find only 3 mentions of this
mismatchRecover
And they all are in the comments.

antlr3baserecognizer.c: /// recovery, override mismatchRecover() and have it
call
antlr3baserecognizer.c: /// differently.  Override and call
mismatchRecover(input, ttype, follow)
antlr3baserecognizer.c: /// single token insertion and deletion. Override
mismatchRecover


There is no such function.

So where it is?  Comments are wrong?


I try now find way disable recover for our Valentina SQL parser...
Have re-read book section. But there only Java code ..
Have check C target docs ‹ nothing about recover ...
Have try search email list ‹ so far nothing useful found...


I think ­ C target docs should have example code ...
Because very different to Java ... No exceptions ...
