Subject [jira] Commented: (LUCENE-814) javacc on Win32 (cygwin) creates wrong line endings - fix them with 'ant replace'
Date Sun, 04 Mar 2007 23:29:50 GMT


Hoss Man commented on LUCENE-814:

Doron: if you are seeing problems with the modified selector, it may be because of the modification
time granularity issue on windows (which is discussed in the <date> selector, but not
the modified selector)

personally, i don't think it's the end of the world to enumerate hte files we expect javacc
to create in the build.xml, but if you want to be craftier then that, i would suggest using
the <containsregexp> selector to look for "Generated By:JavaCC" instead of one based
on the <date> .. that way people who have the misfortune of editing some file right
as the task is running won't wonder why all of their line endings are different.

> "ant javacc" in Windows/Cygwin generates files with wrong line endings (\r  or \r\n instead
of *Nix's \n). 
> I managed to get rid of those using    perl -p -e 's/(\r\n|\n|\r)/\n/g'
> Some useful info on line ending issues is in
> After wasting some time to get rid of those, I modified javacc-QueryParser build.xml
task to take care of that.
> So now QueryParser files created with "ant javacc" are fixed (if required) to have \n
as line ends.
> Should probably do that also for the other javacc targets: javacc-HTMLParser and javacc-StandardAnalyzer(?)
