Colored help by default ?

[bestouff]

Hi,

Would it be possible to have AppSettings::ColoredHelp by default, or at least an easy way to enable it without calling into the underlying clap ?

extern crate clap;
extern crate structopt;
#[macro_use]
extern crate structopt_derive;

use structopt::StructOpt;

#[derive(StructOpt, Debug)]
#[structopt(setting_raw = "clap::AppSettings::ColoredHelp")]
struct Opt {
    #[structopt(short = "s")]
    speed: bool,
    #[structopt(short = "d")]
    debug: bool,
}

fn main() {
    let opt = Opt::from_args();
    println!("{:?}", opt);
}

Does it fix your problem?

[bestouff]

Indeed it does, thanks !
I'm sorry but I didn't understood this from the documentation. Maybe an example would help, do you want me to make a patch ?

Update: when trying that:

  #[derive(StructOpt, Debug)]                                                     
  #[structopt(name = "flashinit", about = "Boot disk populator.",                 
              setting_raw = "clap::AppSettings::ColoredHelp")]                    
  struct Opt {                                                                    
      #[structopt(help = "Disk device or disk image")]                            
      input: String,                                                              
  }                                                                               

I've got this:

   Compiling flashinit v0.1.0 (file:///home/xav/flashinit)
error[E0433]: failed to resolve. Use of undeclared type or module `clap`
  --> src/main.rs:16:10

   |          ^^^^^^^^^ Use of undeclared type or module `clap`

error: aborting due to previous error

error: Could not compile `flashinit`.

To learn more, run the command again with --verbose.

You have to extern crate clap; to expose clap.

I'm open to any improvement of the doc, feel free to submit a PR if you are inspired.

I tag this issue to doc, and close it when the doc is improved on this point.

[bestouff]

Oh, so I have to also add clap as a dependency in Cargo.toml and track its version to match the one from structopt to avoid incompatibilities ... that's not an "easy" way anymore.

[TeXitoi]

StructOpt will always use clap version 2. It should be included in clap in the near future.

[bestouff]

OK, I've added a note in the doc, see #40

[TeXitoi]

fixed by #40
