Changing order of parameters of julia CLI shouldn't change behavior

[s-celles]

Hello,

Following JuliaDocs/Documenter.jl#790 (comment) I noticed that

10:27 $ julia --depwarn=error docs/mk_doc.jl
Documenter: setting up build directory.
Documenter: expanding markdown templates.
 !! No docs found for 'find(m::SortedDict, k_)'. [src/sorted_containers.md]

but

Changing order of parameters of julia CLI shouldn't change behavior

Kind regards

This is to pass arguments into the julia program

➜ echo '@show ARGS' > args.jl
➜ julia args.jl --depwarn=error
ARGS = ["--depwarn=error"]

[s-celles]

$ julia args.jl --depwarn=error docs/mk_doc.jl
ARGS = ["--depwarn=error", "docs/mk_doc.jl"]
$ julia args.jl docs/mk_doc.jl --depwarn=error
ARGS = ["docs/mk_doc.jl", "--depwarn=error"]

The problem here is that there is 2 kind of arguments positional arguments and optional arguments.

The position of an optional argument shouldn't affect behavior of a CLI.

In the first case julia --depwarn=error docs/mk_doc.jl depwarn are considered as error, not in the second one (ie julia docs/mk_doc.jl --depwarn=error)

I know Python and Julia are differents but

main.py

import click

@click.command()
@click.argument('file')
@click.option('--depwarn', default='warn')
def main(file, depwarn):
    print("hello with %s %s" % (file, depwarn))

if __name__ == '__main__':
    main()

$ python main.py --depwarn=error file.txt
hello with file.txt error

$ python main.py file.txt --depwarn=error
hello with file.txt error

$ python main.py file.txt
hello with file.txt warn

Order of an optional doesn't affect behavior of this CLI
I thought that was quite standard in CLI world (especially *nix).

What you did in the original post was the same as

python --depwarn=error main.py

vs

python main.py --depwarn=error

[s-celles]

Ok in one case it's arguments of python cli (or julia cli) and in the other case it's arguments of the Python/Julia script.
Sorry for noise

Thanks @KristofferC
