Hoss Man commented on LUCENE-814:
---------------------------------
i *think* the right solution is to leave the .jj and .java files with
svn:eol-style=native, then modify any target which regenerates a .java file
from a.jj file to use <fixCRLF> without specifying either the "eol" or "cr"
attributes ... the default of <fixCRLF> is to convert the file to the native
format ... so it should synx up.
...but i haven't tested this (no access to windows/cygwin) so i'm not positive
it works.
if that doesn't work, the safest thing to do might be to set svn:eol-style=CRLF
(or any other non variable value) for all of hte generated but commited .java
files, and then modify the ant task that generates them to call <fixCRLF
eol="CRLF"> on those files.
(incidently: are you sure that if you do *everything* in cygwin -- both the
checkout and running "ant javacc" -- you don't wind up with unix style line
endings on all files?)
> javacc on Win32 (cygwin) creates wrong line endings - fix them with 'ant
> replace'

> Components: Build

> "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
> http://en.wikipedia.org/wiki/Newline
> 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(?)
