Elixir bindings for the Typst typesetting system, powered by a Rust NIF. Generate PDFs, PNGs, and SVGs from Typst markup directly in your Elixir application.

• PDF generation — render_to_pdf/3
• PNG generation — render_to_png/3 (one image per page)
• SVG generation — render_to_svg/3 (one SVG per page)
• EEx templating — use familiar Elixir templates to inject dynamic content
• Table formatting — struct-based API for building Typst tables (Typst.Format.Table)
• Virtual file system — pass in-memory assets (images, data) without touching disk
• Font caching — scanned fonts are cached across calls for fast repeated renders
• Precompiled NIF — no Rust toolchain required for most platforms

Add typst to your list of dependencies in mix.exs:

def deps do
  [
    {:typst, "~> 0.4"}
  ]
end

{:ok, pdf} = Typst.render_to_pdf("= Hello World")

{:ok, [png]} = Typst.render_to_png("= Hello World")

{:ok, [svg]} = Typst.render_to_svg("= Hello World")

{:ok, pdf} = Typst.render_to_pdf(
  "= Report for <%= name %>\nDate: <%= date %>",
  name: "Acme Corp",
  date: "2026-03-07"
)

alias Typst.Format.Table
alias Typst.Format.Table.Header

table = %Table{
  columns: 3,
  content: [
    %Header{repeat: true, content: ["Name", "Qty", "Price"]},
    ["Widget", "10", "$5.00"],
    ["Gadget", "3", "$12.50"]
  ]
}

{:ok, pdf} = Typst.render_to_pdf("<%= table %>", table: table)

logo = File.read!("logo.svg")

{:ok, pdf} = Typst.render_to_pdf(
  ~S|#image(read("logo", encoding: none), width: 6cm)|,
  [],
  assets: [logo: logo]
)

All render functions accept these options:

• :extra_fonts — list of directories to search for additional fonts
• :root_dir — root directory for resolving file paths (default: ".")
• :assets — list of {name, binary} pairs for the virtual file system
• :trim — trim blank lines left by EEx tags (default: false)
• :cache_fonts — cache scanned fonts across calls (default: true)
• :pixels_per_pt — pixels per pt unit, only for render_to_png/3 (default: 1.0)
• :pdf_standards — list of PDF/A standard strings to comply with, only for render_to_pdf/3 (default: [])

Full documentation is available at typst.hexdocs.pm.

When you add this package to your mix.exs dependencies, it will by default attempt to use precompiled Rustler assets. To override this behaviour, add {:rustler, ">= 0.0.0"} to your mix.exs, and set the environment variable TYPST_BUILD=true. Alternatively, you can put the following in your config.exs:

config :rustler_precompiled, :force_build, typst: true

Building from source requires a rust toolchain of at least version 1.92.0.

• Make the code changes
• Merge into main
• git push
• Tag the new version and push: git tag v0.x.y && git push --tags
• Wait for CI to build precompiled binaries
• mix rustler_precompiled.download Typst.NIF --all --print
• Checkout the tag: git checkout v0.x.y
• mix hex.publish — run this manually; Hex now prompts for a 2FA token, so it can't be automated
• git checkout main
