Thanks! Looking forward to test this. Is it possible to upgrade from the old version? Or should I make a "clean" install?

If you've installed via pip, it should be enough to run "pip install -U spreads". Be aware of the changed external dependencies, though (chdkptp) :-)

Hi,

Thanks again.

I tried a new install on a new Ubuntu 12.04 and ran into som problems.
After installing all the dependencies in you guide I tried to run the command spread configure and I got this error message.

A stupid mistake of mine... The distribution package was missing some modules...
I already had them installed on my machine, that's why I didn't catch it. I just pushed 0.4.1 to GitHub and PyPi, please run 'pip install -U spreads' and try again.
Sorry!

I don't know if you are interesting in supporting windows? Being a developer I know that it is really difficult/annoying to support a platform you are not using yourself.

But I anyhow managed to install the different dependencies to at least get started, but got the same error with the exiftool, and I think it is because of the util.find_in_path function that doesn't work on windows (partly because of the .exe extension and partly because of the path separator). After a bit of search I found: http://stackoverflow.com/questions/3770 ... -in-python where it is suggested either to use the function distutils.spawn.find_executable (I seems only to work with .exe files, but that should be ok for at least the exiftool) or something like this code for a more general solution, if you want to include also .bat, .cmd, and other executable extensions:

Code: Select all

def which(program):
    def is_exe(fpath):
        return os.path.exists(fpath) and os.access(fpath, os.X_OK)

    def ext_candidates(fpath):
        yield fpath
        for ext in os.environ.get("PATHEXT", "").split(os.pathsep):
            yield fpath + ext

    fpath, fname = os.path.split(program)
    if fpath:
        if is_exe(program):
            return program
    else:
        for path in os.environ["PATH"].split(os.pathsep):
            exe_file = os.path.join(path, program)
            for candidate in ext_candidates(exe_file):
                if is_exe(candidate):
                    return candidate

    return None

@spomwii:
That's a known problem, I unfortunately messed up the packaging for 0.4.1. Once I get back from 30c3, I will prepare a 0.4.2 that should resolve these issues.

@mera451:
My plan for windows-compatibility would actually be to ship a fully bundled version of the Python runtime, the required libraries, spreads+plugins, all external dependencies. That would mean that all external tools would be in a known location, making "util.find_in_path" a lot simpler on Windows systems.
I've been playing around with modifying a WinPython installation to include all of the dependencies and spreads itself, unfortunately my current kernel doesn't like VirtualBox very much and I get kernel panics all the time, which makes the work even more unpleasant ;-)
If you want to give it a shot, contact me and I'll help as much as I can!
