Welcome to Ajisai
Manifesto: Ajisai is a Fractional Dataflow language. Every value flows through operations as a fraction — consumed and producing a remainder, like a TPU pipeline with no materialized intermediates. Each token is spent exactly once, like a UTXO: what enters must exit as result + remainder, preserving the conservation law.
What is Ajisai?
Ajisai is a Fractional Dataflow programming language (FORTH-inherited postfix notation), featuring a WebAssembly Runtime and an interactive web-based GUI.
Values flow through a consume/remainder chain: each operation consumes its input and forwards the remainder, analogous to TPU streaming (no materialized intermediates) and UTXO spending (each token used exactly once).
The name "Ajisai" (hydrangea in Japanese) represents how small words come together to form functionality, like how small flowers form a hydrangea cluster.
Fractional Dataflow
FORTH-inherited postfix notation with remainder passing — values flow, never stall
Stream-First Vector Processing
NumPy/APL-style broadcasting and tensor operations over fraction flows
Conservation-Preserving Fraction Arithmetic
All numbers as fractions — no rounding errors, conservation law guaranteed
WebAssembly Runtime
Rust core compiled to WASM for fast browser execution
Quick Example
# Vector creation and operations
[ 1 2 3 ] # 1D vector
[ [ 1 2 ] [ 3 4 ] ] # 2D nested vector
# Broadcasting arithmetic
[ 5 ] [ 1 2 3 ] + # Result: [ 6 7 8 ]
# Custom word definition (code block syntax)
{ [ 2 ] * } 'DOUBLE' DEF
[ 5 ] DOUBLE # Result: [ 10 ]
# Higher-order functions with pipeline
[ 1 2 3 4 5 ]
== 'DOUBLE' MAP # Result: [ 2 4 6 8 10 ]
== [ 0 ] { + } FOLD # Sum: [ 30 ]Get Started
