Python tower.strip_whitespace函数代码示例

    """We piggyback on jinja2's babel_extract() (really, Babel's extract_*
    functions) but they don't support some things we need so this function will
    tweak the message.  Specifically:

        1) We strip whitespace from the msgid.  Jinja2 will only strip
            whitespace from the ends of a string so linebreaks show up in
            your .po files still.

        2) Babel doesn't support context (msgctxt).  We hack that in ourselves
            here.
