The Native
Language of Agents

Models write pseudocode. Tungsten runs it.

1# Currency and percentages 2price = $499.99 3 4<< price - 15% # => ≈$424.99 5<< price - 15% + 8.25% # => ≈$460.05 6 7# Units of measurement 8c = 299_792_458 m/s 9m = 1 kg 10 11<< e = m·c² # => ≈8.988×10¹⁶ J 12 13<< 3 ft + 12 in # => 4 ft 14<< 10 ft * 10 ft # => 100 ft² 15<< 2 m + 2 lbs # => error: dimension mismatch

One-line install

Clone, build, and link

Installs into ~/.tungsten, builds the compiler, and links tungsten onto your path.

curl -fsSL https://tungsten-lang.org/install | sh

From a source checkout

Bootstrap, then brief the agent

Build a stage-one compiler, then emit the compact language primer and absolute paths to agent tooling.

bin/tungsten bootstrap && bin/tungsten start --agent

  • Argon

    A manpage-driven CLI parser: define options once in the documentation and parse them without a second schema.

  • Flame

    A profiler that turns Tungsten or arbitrary process stacks into interactive SVG flame graphs, diffs, and trace exports.

  • Forge

    A multi-threaded HTTP server for Tungsten and Carbide, with TLS and HTTP/1.1, HTTP/2, and HTTP/3 support.

  • Hammer

    An M:N HTTP load generator that reports throughput, latency percentiles, and errors across concurrent workers.

  • Koala

    DataFrames, linear algebra, preprocessing pipelines, metrics, and sklearn-style machine learning in Tungsten.

  • wasSAT + WRAT

    A native CDCL SAT solver paired with an independent streaming checker for WRAT, LRAT, and DRAT refutations.

  • Metaflip

    An exact-gated CPU and Metal search fleet for low-rank matrix-multiplication decompositions over GF(2).

💰

Tungsten Makes Cents

First-class support for dollars, cents, and percentages. No more money bugs from floats.

<< $3.50 - 25¢ # => $3.25

📐

Units of Measurement

Meters, feet, kilograms - with automatic conversion and dimensional analysis. Mismatched units caught at compile-time.

<< 1 cm * 1 cm * 1 cm # => 1 cm³

🎯

Decimals by Default

3.14 is an exact decimal, not an IEEE float. Approximation is opt-in with ~ — so the default never surprises your accountant.

exact = 3.14 # Decimal
approx = ~3.14 # Float

A Touch of Class

Define a class with +, a method with ->, and output with <<.

Arity after the slash defines anonymous arguments.

Instance variables are assigned in the constructor with @. The ro suffix makes them read-only.

The prime notation (x') refers to the same-named property on the argument: x - x' means "my x minus their x."

Δx compacts it further.

1+ Point 2 -> new(@x, @y, @z) ro 3 4 -> distance/1 5 dx = x - x' 6 dy = y - y' 7 dz = z - z' 8 9 (dx.sq + dy.sq + dz.sq).sqrt 10 11 # or, if you prefer 12 -> distance/1 13 √(Δx² + Δy² + Δz²) 14 15<< Point(3, 4, 0).distance(Point(0, 0, 0)) # => 5

Start your next agent in Tungsten

Give the model the primer. Give the compiler its answer.

$ curl -fsSL https://tungsten-lang.org/install | sh

✓ stage 1 ≡ stage 2 — the compiler reproduces itself

✓ linked ~/.local/bin/tungsten

$ echo '<< "Hello, W!"' > hello.w

$ tungsten hello.w

Hello, W!
