So I migrated from clap v3.x to v4.x. I am not getting the color during the help output as I got it in v3.x. Everything was completely white. I used the basic code from the example (https://github.com/clap-rs/clap/blob/master/examples/git.rs). Below are two images showing the output of v3 (the first one) and the production from v4 (the second one).
My question is, how to add the colors?
I tried setting the color to Always but no help
Create the styles yourself
pub fn get_styles() -> clap::builder::Styles {
clap::builder::Styles::styled()
.usage(
anstyle::Style::new()
.bold()
.underline()
.fg_color(Some(anstyle::Color::Ansi(anstyle::AnsiColor::Yellow))),
)
.header(
anstyle::Style::new()
.bold()
.underline()
.fg_color(Some(anstyle::Color::Ansi(anstyle::AnsiColor::Yellow))),
)
.literal(
anstyle::Style::new().fg_color(Some(anstyle::Color::Ansi(anstyle::AnsiColor::Green))),
)
.invalid(
anstyle::Style::new()
.bold()
.fg_color(Some(anstyle::Color::Ansi(anstyle::AnsiColor::Red))),
)
.error(
anstyle::Style::new()
.bold()
.fg_color(Some(anstyle::Color::Ansi(anstyle::AnsiColor::Red))),
)
.valid(
anstyle::Style::new()
.bold()
.underline()
.fg_color(Some(anstyle::Color::Ansi(anstyle::AnsiColor::Green))),
)
.placeholder(
anstyle::Style::new().fg_color(Some(anstyle::Color::Ansi(anstyle::AnsiColor::White))),
)
}
And then call it with styles
#[command(styles=get_styles())]
pub struct CliArgs {
...
}
