Subject [jira] Updated: (LUCENE-814) javacc on Win32 (cygwin) creates wrong line endings - fix them with 'ant replace'
Date Wed, 07 Mar 2007 22:09:24 GMT


Doron Cohen updated LUCENE-814:

    Attachment: 814.javacc.fixcrlf.common-build.patch

It was nice if javaCC had a 'native-eol' option. It doesn't, and the modification time is
used in attempt to imitate the availability of such an option.

But I think you are right, there should be no harm in fixing crlf for all the files containing
the "generated" string - I'll go and commit it without the date check. 

For the javacc-clean comment - having it deleting all the files containing this string will
almost work - except for ParseException in standardTokenizer - where a modified version is
maintained. So we could modify javacc-clean to delete all Java files containing that "generated"
string, except for ParseException in standardTokenizer. But if we want to do this, it rather
be in a separate issue. (Also, I noticed that contrib/surround has no javacc-clean, and contrib/misc/o.a.l/queryParser/precedence
has no javacc target.)

> "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(?)
