Question

I have a python project under SVN, and I\'m wanting to display the version number when it is run. Is there any way of doing this (such as automatically running a short scrip

You could do this programmatically by parsing the output from 'svn info --xml' to an xml Element:

def get_svn_rev(dir: Union[str, Path]) -> str:
    """Get the svn revision of the given directory"""
    dir = str(dir)
    svn_info_cmd = ['svn', 'info', '--xml', dir]
    print(' '.join(svn_info_cmd))
    svn_info_process = subprocess.run(svn_info_cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
    if svn_info_process.returncode:
        eprint(svn_info_process.stderr.decode().strip())
        raise subprocess.CalledProcessError(returncode=svn_info_process.returncode, cmd=svn_info_cmd,
                                            output=svn_info_process.stdout,
                                            stderr=svn_info_process.stderr)
    else:
        info = ElementTree.fromstring(svn_info_process.stdout.decode().strip())
        entry = info.find('entry')
        revision = entry.get('revision')

    return revision
