RE: Wanted: Help translating classpath from CMD.EXE to bash

2005-10-31 Thread Siegfried Heintze

I figured it out. This does work after all:

CLASSPATH=.\;c\:\\dev\\xalan\\xalan-j_2_7_0\\samples\\xsltcservlet.jar\;c\:\
\dev\\xalan\\xalan-j_2_7_0\\samples\\xsltcejb.jar\;c\:\\dev\\xalan\\xalan-j_
2_7_0\\samples\\xsltcbrazil.jar\;c\:\\dev\\xalan\\xalan-j_2_7_0\\samples\\xs

\\xalan-j_2_7_0\\xml-apis.jar\;c\:\\dev\\xalan\\xalan-j_2_7_0\\xsltc.jar
export CLASSPATH
javac -g ApplyXPathDOM.java

One has to escape the colons and the semi colons. I don't understand why I
have to escape the colons too -- but it works.

Thanks for the example for the java/bash wrappers -- I think I understand
now.

I should've been clearer, and said "you can use 'cygpath -p' to convert
*between* a POSIX-style path and a Win32-style one".  "cygpath -[u]p" (the
"u" is optional) will convert from a Win32 path to a POSIX one, whereas
"cygpath -wp" will convert from a POSIX path to a Win32 one.  For more
details, see "man cygpath", as Larry said.

What exactly didn't work here?  What were the errors?

Nope.  I haven't really had time to package them properly.  I won't be
able to write full-fledged documentation, but I'm willing to answer
questions and accept documentation patches against the CVS repository
above.  Care to help out?

> What kind of wrappers are these?

They are wrappers around the "java", "javac", etc, executables.  Just make
sure they precede the real executables in the PATH.  They will basically
invoke the real ones, having translated the known path arguments to POSIX
format.  They will not translate all arguments -- if you pass filenames to
your Java program, you're responsible for translating those.  But they
help (a lot, actually -- I use them constantly on my machine).

They are wrapper programs written in bash.

Sure.  You can run

/usr/local/bin/java -classpath /home/me/jars/a.jar:/home/me/classes
SomeClass

And it'll call the Windows Java executable with the right paths.

You'll have to provide more details on what exactly didn't work in your
attempt.

I think I need to go the other way. Given a CLASSPATH variable in windows,
how do I convert it to cygwin? Do I use ":" to separate the elements, or do
I use "\;". If I use ":", what about the windows device names?

It seems to me this should have worked, but it does not:
 * CLASSPATH=.\;c:\\dev\\xalan\\xalan-j_2_7_0\\xsltcservlet.jar\;others
 * export $CLASSPATH
 * echo ${CLASSPATH}
 * javac myprogram.java

If you're running from bash or any other Cygwin shell, then the path is
already in POSIX form.  'javac' won't understand this, since it is a
Windows program.  'cygpath' is the way to convert between POSIX paths and
Windows/DOS, forward and back.  In your case, you want POSIX->Windows/DOS
conversion.  See 'man cygpath' for more details.

OK, is there any documentation? What kind of wrappers are these? I have
never heard of bash wrappers before. (hmmm... bash wrappers, sounds like a
new genre of music! -- maybe something like slam dancing?)

How about an example? That would probably suffice.

Well, even if I get Igor's bash wrappers to work, I'm kinda curious why my
attempt did not.

As someone mentioned, you can use "cygpath -p" to convert a POSIX-style
path into a Win32-style one.

Alternatively, you can try using my java wrapper scripts that will do the
translation automatically for you (the scripts can be found at
;
you'll need to edit the scripts to point them to your Java installation
directory).

Or, since you're doing XML processing in Java, you might find XJ
() useful.  There's a prototype on IBM
alphaWorks (a free download), and it works under Cygwin.

HTH,
Igor

If I understand your question you can convert paths to and from
dos by using the cygpath command.
