This was executed:
$ latexdiff report_old.tex report_new.tex > report_diff.tex
After 11 hours the process is still running hard with CPU pegged
around 99% according to /top/. CPU fan is running which also indicates
hard work is being done. There is no output to indicate how much
progress has been made.
When compiled, the document yields 13 pages in PDF form. I do not
imagine that 11+ hours is reasonable for that volume. Bug fixes and
enhancements are needed.
① There is likely some kind of faulty logic such as an endless loop
② A progress indicator is needed
③ A detailed debug log is needed
④ Periodic assessments should be made throughout the processing as to
whether reasonable progress is being made. If an hour is spent on a
normal sized paragraph, the tool should abort and perhaps give an
indication of which segment of text is exceeding time
thresholds. This should be configurable but many users don’t know
what to expect so there should be a reasonable default.
I’ve seen latexdiff take forever in past executions and had to give up
and kill it. The document latexdiff struggles with at the moment is a
bilingual document that uses parcolumns to produce a left and right
column.
