Math::String::Charset::Wordlist
2003-02-06 v0.01 Tels
* first version
2003-04-14 v0.02 Tels
* fix for scale not beeing a legal parameter to new()
* added method copy() (with special case for Tie::File object)
2003-04-27 v0.03 Tels 81 tests
* added: file(), class()
* fixed: str2num: use the "normal" sorting of the wordlist (like
"sort -u" produces), instead of "shortest strings first"
* fixed: ones(), start(), end(), char()
* made it's own distribution with XS code to replace File::Tie
_file(), _free(), _offset() and _record()
* fixed: str2num(): use $self->{_len}->numify() instead of $self->count()
This makes the search _much_ faster since it no longer uses
BigInt math (e.g. 1800/s vs. 70/s)
2003-04-27 v0.04 Tels 152 tests
* speedup str2num: just set $leftstr/$rightstr from $middlestr instead of
fetching them over and over. (2470/s instead of 1800/s)
* _offset(): return undef when a negative record number is passed
* offset(-$n): return offset counting from last record backwards
* _record(): increase limit from 1024 to 8192 bytes. (still, fixed limit is
baaad...)
* _record(): remove 0x0A and 0x0D from record end (to cater for win32 files)
