This module replicates the functionality in Texinfo::ParserNonXS.


=====================================================================
Notes -

should be able to debug with gdb.  Add

./configure PERL_EXT_CFLAGS='-g -O0'

For individual tests can do "gdb perl" in ../../perl followed by e.g.

(gdb) r -w t/27float.t comment_space_comand_in_float

After a single run can set breakpoints.

How to debug with valgrind -
export PERL5LIB to the value in the makeinfo script

with alias VAL='valgrind --log-file=val.log', can do from the doc directory e.g.

VAL perl ../tta/perl/texi2any.pl texinfo.texi

also

valgrind --vgdb-error=0 perl ../tta/perl/texi2any.pl texinfo.texi

=====================================================================

To see contents of leaked memory

Run with valgrind, in the ../../perl directory e.g.

valgrind --leak-check=full --vgdb-error=0 --vgdb-stop-at=exit \
  perl -w t/18itemize.t

at end of run, in gdb:

(gdb) monitor leak_check definiteleak any
==10409== 480 (80 direct, 400 indirect) bytes in 1 blocks are definitely lost in loss record 3,261 of 4,374

...

(gbd) monitor block_list 3261


Get log files specific to tests with

$ grep '^\['\' t/18itemize.t | sed -e 's/^..//' -e 's/..$//' >test-list
$ for t in `cat test-list` ;  do valgrind --log-file=val.log.$t  \
--leak-check=full perl -w t/18itemize.t $t ; done


%

checking memory leaks
install Perl::Destruct::Level via cpan
then e.g.

VAL --leak-check=full perl -M'Perl::Destruct::Level level => 1' -w t/02coverage.t
