A builder for base16 and base24 templates using the 0.11.1 builder specification.

This repo contains a command-line tool, tinted-builder-rust, to build base16 and base24 templates. It is also contains a library crate, tinted-builder, which you can use to directly build templates within your own Rust application.

The following is a table of the available subcommands for the CLI tool (tinted-builder-rust), including the descriptions and any notable arguments.

tinted-builder-rust implements the 0.11.1 builder specification. This specification details the scheme yaml format or schema as well as the variables the builder should provide when rendering template mustache file. Have a look at the builder specification document for more details.

In addition to Base16/Base24, this repository provides Tinted8 support in the library crate and CLI. Tinted8 simplifies schemes into a small, consistent set of keys and lets builders derive variants and supplemental colors.

• Supported specs: Tinted8 Styling ~0.2.0, Tinted8 Builder ~0.2.0.
• UI keys use flat, kebab-case names (see below).

Example minimal Tinted8 scheme (YAML):

scheme:
  system: "tinted8"
  supports:
    styling-spec: "0.2.0"
  author: "User <user@example.com>"
  name: "Ayu Mirage"
  slug: "ayu-mirage"
variant: "dark"
palette:
  black:   "#131721"
  red:     "#f07178"
  green:   "#b8cc52"
  yellow:  "#ffb454"
  blue:    "#59c2ff"
  magenta: "#d2a6ff"
  cyan:    "#95e6cb"
  white:   "#e6e1cf"
ui:
  background.normal: "#131721"
  foreground.normal: "#e6e1cf"

Example templates/config.yaml for a Tinted8 template:

default:
  filename: "output/{{ scheme-system }}-{{ scheme-slug }}.ext"
  supported-systems: [tinted8]
  supports:
    tinted8-styling: ">=0.1.0"
    tinted8-builder: ">=0.1.0"

Example Mustache variables in a Tinted8 template:

• {{ scheme.name }} — scheme name
• {{ scheme.slug }} — scheme slug
• {{ palette.blue.bright.hex }} — hex of blue bright variant (derived if missing)
• {{ ui.background.hex }} — hex of the UI background color
• {{ syntax.string.hex }} — hex for the default string color

Notes:

• The builder derives missing dim/bright variants and supplemental gray, orange, and brown per the Tinted8 Builder spec.
• Decimal channels are normalized 0–1 and available as strings at rgb/rgb16/dec under each color (e.g. palette.red.normal.dec.r).

The CLI returns structured error codes grouped by stage. See specs/tinted8/builder.md for details.

• E1xx — Intake & System Validation (e.g., E001 invalid system, E110 unknown system)
• E2xx — Spec Compatibility (E002/E003 version mismatches)
• E3xx — Template Configuration (E300–E305 missing/invalid config or templates)
• E4xx — Build-Time Selection (E400 no schemes found)

This library exposes a Scheme and Template struct which you can use to generate your own themes using base16 and base24 templates and 0.11.1 compliant base16 and base24 scheme files.

Internally tinted-builder-rust uses ribboncurls to render the templates.

cargo add tinted-builder-rust

use tinted_builder_rust::{Scheme, Template};
use std::fs::read_to_string;

let template_str = read_to_string("path/to/template.mustache").unwrap();
let scheme_str = read_to_string("path/to/scheme.yml").unwrap();
let scheme = Scheme::Base16(serde_yaml::from_str(&scheme_str).unwrap());
let template = Template::new(template_str, scheme);

template
    .render()
    .unwrap();

### Programmatic CLI usage (build helper)

The CLI crate also exposes a small helper to drive a template build from code:

```rust
// in Cargo.toml: tinted-builder-rust = { version = "*" }

let template_dir = std::path::PathBuf::from("/path/to/template");
let schemes_dir = std::path::PathBuf::from("/path/to/schemes");

// Quiet output, returns Result<(), anyhow::Error>
if let Err(err) = tinted_builder_rust::build(&template_dir, &schemes_dir, true) {
    eprintln!("build failed: {err}");
}

Common errors include E300/E301/E302 (missing tinted8 supports), E303 (missing mustache), E304 (invalid filename config), E305 (missing/invalid template config), and E400 (no schemes found).

The Scheme struct is as follows:

```rust
use std::collections::HashMap;
use tinted_builder::{SchemeSystem, SchemeVariant};

pub struct Scheme {
    pub system: SchemeSystem,
    pub name: String,
    pub slug: String,
    pub author: String,
    pub description: Option<String>,
    pub variant: SchemeVariant,
    pub palette: HashMap<String, Color>,
}

pub struct Color {
    pub hex: (String, String, String),
    pub rgb: (u8, u8, u8),
    pub dec: (f32, f32, f32),
}

Template::new The Template struct simply sets the content provided to it via Template::new.

template.render_to_file(&scheme) takes the scheme and generates the variables defined in the 0.11.1 builder specification.
