Silicate

Python bindings for Silicon's renderer — create beautiful images of your source code, powered by Rust.

Unlike wrapper approaches that shell out to a CLI, Silicate uses PyO3 to call Silicon's Rust library directly, giving you native performance with a clean Python API.

Installation

uv add silicate

Build from source (requires Rust toolchain):

git clone --recurse-submodules https://github.com/alltuner/silicate.git
cd silicate
uv sync

Usage

import silicate

# Generate PNG bytes
png_bytes = silicate.generate(
    "print('Hello, World!')",
    language="python",
    theme="Dracula",
)

# Save directly to file
silicate.to_file(
    "fn main() { println!(\"Hello!\"); }",
    "output.png",
    language="rs",
    theme="Nord",
    window_title="main.rs",
)

# Explore available themes and languages
print(silicate.list_themes())
print(silicate.list_languages())
