toiletcli

A tiny framework for command line applications.

Each module can be disabled/enabled via default features: toml [features] default = ["flags", "colors", "escapes"]

This crate contains examples and a demo cat program, which can be built/run with: console $ cargo run --example <cat/flags/colors/escapes>

Usage

pub mod flags;

```rust //! Command line flag parsing.

use std::env::args;

use toiletcli::flags; use toiletcli::flags::*;

let mut color: String; let mut show_help: bool;

let mut flags = flags!( color: StringFlag, ["--color", "-c"], show_help: BoolFlag, ["--help"] );

let args = parse_flags(&mut args(), &mut flags); ```

pub mod colors;

``rust //! ANSI terminal colors as enums that all implementDisplayandFromStr` traits.

use toiletcli::colors::Color;

println!("{}{}This is red text on blue background!{}", Color::Red, Color::Blue.bg(), Style::Reset);

let weirdstyle = StyleBuilder::new() .foreground(Color::Byte(93)) .background(Color::fromstr("black").unwrap()) .addstyle(Style::Underlined) .underlinecolor(Color::RGB(0, 255, 0)) .underline_style(UnderlineStyle::Curly) .build();

println!("{}RGB purple on black background with RGB curly green underline!{}", weird_style, Style::Reset); ```

pub mod escapes;

``rust //! Enums for ANSI terminal cursor manipulation that all implementDisplay`.

use toiletcli::escapes::*;

println!("This is a 'word' that will be replaced!{}bird", Cursor::Position(12)); // This is a 'bird' that will be replaced!

println!("This is a '{}dog' that will be replaced too!{}cat", Cursor::Save, Cursor::Restore); // This is a 'cat' that will be replaced too!

print!("{}", System::SetTitle("hello")); // Look at the title :3 ```

pub mod common;

```rust //! Common functions.

use toiletcli::common;

let path = "toilet/bin/program"; let name = common::namefrompath(path);

assert_eq!(name, "program"); ```
