Zsh Module  

This is a high level crate that allows you to define your own zsh module. It is in a very early state but it can be used to define commands.

In the future, most zsh module functionality will be added. Feel free to send a PR if you would like to add more functionality :)

Features:

• Define custom builtin commands
  • Define and query used flags
• Call into zsh
• Query environment variables
  • As a workaround: can be done using the std::os APIs.
• Use zsh's current stdin fd.
  • You can use std::io::stdin, but it can break in specific ocasions.
• Define custom builtin math functions
• Define custom global variables
• More to come!

Getting started

Take a look at our online documentation for a quick guide.

Example module

Making a module is very easy, here's an excerpt from our example module greeter

use zsh_module::{Builtin, MaybeError, Module, ModuleBuilder, Opts};

// Notice how this module gets installed as `rgreeter`
zsh_module::export_module!(rgreeter, setup);

struct Greeter;

impl Greeter {
    fn greet_cmd(&mut self, _name: &str, _args: &[&str], _opts: Opts) -> MaybeError {
        println!("Hello, world!");
        Ok(())
    }
}

fn setup() -> Result<Module, Box<dyn std::error::Error>> {
    let module = ModuleBuilder::new(Greeter)
        .builtin(Greeter::greet_cmd, Builtin::new("greet"))
        .build();
    Ok(module)
}
