add an attribute on option argument to let `from_str_fn` can return `Vec<T>` or `Option<T>` as-is

7

In some cases I don't expect `Vec` to mean that the argument can be repeated, or `Option` to mean that the argument is optional. For example an argument expects a...

Consider making serde dependency optional (as a feature)

1

First: Thanks for writing & publishing argh as libre software! It's been a joy to use and solves the problem without dependencies. Or at least it used to, hence this...

Consider this example/test source code: ```rust use argh::FromArgs; #[derive(FromArgs)] /// Example struct Args { #[argh(subcommand)] subcommand: Subcommand, } #[derive(FromArgs)] #[argh(subcommand)] enum Subcommand { One(SubcommandOption1), } #[derive(FromArgs)] #[argh(subcommand, name = "one")]...

Added in https://github.com/google/argh/pull/76 but not documented since then, it would be nice if this function is more discoverable.

`argh_shared`: change serde features to allow `no_std` use

2

The `argh_shared` crate depends on `serde`, which uses `std` in its default configuration. This makes it incompatible with `no_std` crates. As per the [`serde` docs](https://serde.rs/no-std.html), adding `default-features = false` makes...

Is there any way to specify to argh that any: ``` #[argh(positional, greedy)] /// command line args args: Vec, ``` arg options are expected to be totally "raw" (for lack...

Support something like --helpfull which displays help for all subcommands

2

It would be really nice to have an option to show the help for all subcommands vs. having to run --help for each subcommand recursively.

Single dash is parsed as unrecognized argument

1

According to the Fuchsia command line rubric, and general Unix practice, a single dash is not allowed as a key or switch, but that's how argh treats it, because it...

Allow to disable requirement for uncapitalized descriptions

1

This strict requirement makes sense only for programs designed for Fuchsia, no other system has this convention. This commit adds a type-level attribute `lax_description` that disables the option descriptions validation...
