Dear Sirs,
I have been working with a perl-program using PDF::Table. I
encountered a problem with the table-subroutine entering a never
ending loop at the point where long words are split to shorter ones.
I looked at the code, and discovered the problem in the exit
condition for the loop.
I fixed the problem by replacing the whole loop-structure with one
global replace-regexp statement. I ask you to consider including my
patch (attached) to the PDF::Table v. 0.9.3. I think the new
implemetation is even more efficient than the original one as there
is no explicit loop in the code. also, I added statement modifier
testing whether the desired maximum word length is greater than 0
While tracking down the bug, I discovered that the problem was caused
by non-empty $2 at the point where PDF::Table::table was called. A
workaround was to do a dummy match $_ =~ m/./; just before the call
and thus reset $2.
Best regards,
Petri Kaurinkoski
