problem with type argument parsing

[cd...@mutable.host]

Hi,

I am coming across a problem with argument parsing, I am not sure if it is me missing something or if it is a bug. I would value your comments.


The attached __broken type illustrates this.


$ cdist config -v localhost -i - <<EOF
__broken /tmp/test --arg '-n' --arg '-e'
EOF
INFO: localhost: Starting configuration run
ERROR: localhost: /bin/sh -e /tmp/cdist.stdin.02i9h1cy: ['/bin/sh', '-e', '/tmp/cdist.stdin.02i9h1cy']

Error processing initial manifest
=================================
path: /tmp/cdist.stdin.02i9h1cy

init:stderr
-----------
usage: __broken [--arg ARG] object_id
__broken: error: argument --arg: expected one argument


ERROR: cdist: Failed to configure the following hosts: localhost
$

Thanks.

Hi,

Not sure, but does it help to escape the - passed to the arg? So --arg '\-n'?

Regards,

Mark

Thanks for your reply,

Unfortunately no joy.
'\-n' and "-n" don't seem to work.
On the other hand, a more complex argument does work:
--arg '-e "s/bob/smith/g"'

I don't know cdist internals, so wouldn't know where to begin debugging.

Thanks.

Good morning,

the "parsing" question is very simple: we're using plain pythor
argparse:

https://docs.python.org/3/library/argparse.html

Shell wise, -n and '-n' are the same thing when being seen by the
program. What you are probably looking for is "--", but that stops
processing parameters.

Note: the problem is not with cdist, but a logical one ("when is -x
an argument, when a parameter"?)

Cheers,

Nico
