Re: [go-nuts] Equivalent of os.Args but on custom input
I do something similar for some of my interactive tools and ended up
writing this: https://github.com/gobs/args.
If interested the command parser is here: https://github.com/gobs/cmd.

Re: [go-nuts] Equivalent of os.Args but on custom input
os.Args simply exposes the arguments passed to the program by the operating
system. On UNIX this is typically called "argv" in C/C++ programs. The
parsing of those strings into two arguments is done by the shell that runs
your elvish program. It is not done by os.Args. I'm not aware of any
functionality in the standard Go runtime that does what you want. There are
probably third-party packages which do it that you could import. Or, roll
your own CLI parser as shown in the stackoverflow question.

[go-nuts] Equivalent of os.Args but on custom input
Hi,
I'm working on a program which will have a prompt to enter commands like:
add "foo bar"
I need what os.Args provides but on custom input so to above input I would
like to get:
[]string{"add", "foo bar"}
Package os uses runtime_args(), and it isn't exported nor accepts input.
Any idea what can I use instead? As a fallback, I can always implement
something like https://stackoverflow.com/a/46973603, but maybe there is a
smarter way to do it.
