Madhavan updated CASSANDRA-17236:
---------------------------------
Description:
Today we do only support the `–version` long option/form for cqlsh and this
enhancement Jira is to request that we also offer a shorter version `-v` to
cqlsh. This will have consistency benefits with other tools and even match with
what we have at `bin/cassandra -v` option for instance.
Today, `cqlsh` does support `--v` to get the version which is different than
the single dashed short form that is available at many other tools. Thanks to
Ekaterina for finding this. It looks like this is stemming from Python's parse
mechanism which is detailed here,
[https://docs.python.org/2.7/library/optparse.html#printing-a-version-string].
[https://github.com/apache/cassandra/blob/trunk/bin/cqlsh.py#L194-L196]
{quote}parser = optparse.OptionParser(description=description, epilog=epilog,
usage="Usage: %prog [options] [host [port]]",
version='cqlsh ' + version)
{quote}
{{$ bin/cqlsh --v}}
{{cqlsh 6.0.0}}
This looks like a weird implementation at Python. Both (\-\-help) and
(\-\-version) options are stemming from here,
[https://github.com/python/cpython/blob/2.7/Lib/optparse.py#L1248-L1256] and
they did decide to ignore the short form option for version and it somehow
automatically takes the {{-v}} option to spit the version info.
