Derive macros for the gilt terminal formatting library.

This crate provides the #[derive(Table)], #[derive(Panel)], #[derive(Tree)], #[derive(Columns)], #[derive(Rule)], #[derive(Inspect)], and #[derive(Renderable)] macros that generate widget conversion methods and trait implementations for structs.

Table Example

use gilt::Table;

#[derive(Table)]
#[table(title = "Employees", box_style = "ROUNDED", header_style = "bold cyan")]
struct Employee {
    #[column(header = "Full Name", style = "bold")]
    name: String,
    #[column(justify = "right")]
    age: u32,
    #[column(skip)]
    internal_id: u64,
    #[column(header = "Dept", style = "green", min_width = 10)]
    department: String,
}

let employees = vec![
    Employee {
        name: "Alice".into(),
        age: 30,
        internal_id: 1001,
        department: "Engineering".into(),
    },
    Employee {
        name: "Bob".into(),
        age: 25,
        internal_id: 1002,
        department: "Marketing".into(),
    },
];
let table = Employee::to_table(&employees);

Panel Example

use gilt::Panel;

#[derive(Panel)]
#[panel(title = "Server Status", box_style = "ROUNDED", border_style = "blue")]
struct ServerStatus {
    #[field(label = "Host", style = "bold cyan")]
    name: String,
    #[field(label = "CPU %", style = "yellow")]
    cpu: f32,
    #[field(skip)]
    internal_id: u64,
    #[field(label = "Memory", style = "green")]
    memory: f32,
}

let status = ServerStatus {
    name: "web-01".into(),
    cpu: 42.5,
    internal_id: 1001,
    memory: 67.3,
};
let panel = status.to_panel();
