Subject [jira] Commented: (LUCENE-814) javacc on Win32 (cygwin) creates wrong line endings - fix them with 'ant replace'
Date Sat, 24 Feb 2007 05:58:05 GMT


Hoss Man commented on LUCENE-814:

a few comments in no particular order...

1) there is a core ant task called <fixCRLF> that should be able to do what your macro

2) this may be related to the fact that svn:eol-style for QueryParser.jj is set to native,
yet cygwin likes files to be unix style -- this causes problems with bash scripts in cygwin,
so depending on how hte javacc task works (since it requires you to specify a javacchome i'm
guessing it does a system exex) under cygwin it may be a similar issue (ie: fixable by changing
the svn:eol-style to be explicit)

> "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(?)
