Arguments from file example ? about kingpin HOT 10 CLOSED

It's simply @filename where there is one argument/flag per line. Perhaps the documentation could use some expansion though.

from kingpin.

And use kingpin.ParseWithFileExpansion() instead of kingpin.Parse() to expand automatically.

@alecthomas Thank you.

# cat config
127.0.0.1
8084

one more question, is that passable to using named arguments ? e.g.

$ cat config
host=127.0.0.1
port=8084

from kingpin.

If by named arguments you mean flags, then yes:

--host=127.0.0.1
--port=8084

If you're talking about positional arguments, then no it does not support naming.

Thank you !

Even with this, there is no example for how to actually use a config file. Can someone post a CLI example which uses a config file?

from kingpin.

$ cat flags
--some-flag
--some-other-flag=some arg
$ myapp @flags

from kingpin.

Thanks @alecthomas. :)

I tried this in combination with command line entries and I got the following:

$ cat flags
--some-flag
--some-other-flag=some arg
$ myapp command --pass="xyz" @flags

I got:

$ myapp command --pass="xyz" @flags
panic: runtime error: slice bounds out of range

If I use the @flags, does that mean I can't use the CLI as well?

This is a known issue (#148). @ support is not great :\

from kingpin.

Ahh. Ok. I had not seen that issue. Thanks.

I am able to get it working now if put all commands and subcommands in the file, but not if I add anything in the command line arguments.
