[Jython-users] jythonc bug concerning long file/path names

[Syver E. <sy...@cy...>]

Greetings jython-users list readers,  I come in peace! (This is my first
posting you know ;-) Very cool to layer python on top of java.

I have a minor patch to suggest for jythonc that tripped me up some time,
while simultaneously fooling around with the classpath (new to java).

jythonc in it's current incarnation doesn't seem to handle long filenames
too well, or actually it's kindof javac's fault. When compiling from a
directory whose path consists of spaces javac trips up when it is fed the
current directory in the classpath.

The following quick and dirty fix makes it work fine on my machine:
As you can see the only thing it does is enclose all the paths in the
classpath with "" so that javac won't trip up on directory names that looks
like this:
h:\my documents\tools\python source

From javac.py in tools:

def fixClasspath(cpath):
    temp = []
    for each in cpath:
        temp.append('"' + each + '"')
    return temp

From the function definition compile
<snip>
   # new:
    # Classpath:
    #   1. python.jythonc.classpath property
    #   +
    #   2. java.class.path property
    #   +
    #   3. sourcedir
    #   +
    #   4. sys.path
    if cpath is None:
        sep = java.io.File.pathSeparator
        cpath = []
        part = sys.registry.getProperty("python.jythonc.classpath")
        if part != None:
            cpath.extend(part.split(sep))
        part = getClasspath()
        if part != None:
            cpath.extend(part.split(sep))
        if sourcedir:
            cpath.append(sourcedir)
        cpath.extend(sys.path)

        cpath = fixClasspath(cpath) # fix by Syver Enstad 5. feb. 2001
        cpath = sep.join(cpath)
    cmd.extend([cpathopt, cpath])
    cmd.extend(files)
    print 'Compiling with args:', cmd
