@rigidity/clvm v4.0.0

CLVM

A browser friendly implementation of clvm in TypeScript, based off of the Chia Network implementation written in Python.

Introduction

Chialisp is an on-chain smart coin programming language developed by the Chia Network. It is compiled and then executed by the Chialisp Virtual Machine, or CLVM for short.

This particular implementation is written with TypeScript, and is not bindings to native code. This allows it to be used in the browser as well. However, if you prefer native bindings, you should check out this library instead.

Usage

You can learn more about how this language works here. This is a implementation and should work as expected, but in any case that it differs, please open an issue.

By design, the functions and methods exposed by this library are synchronous and everything is exported for ease of use.

Since it is written in TypeScript, there are built-in typings for IntelliSense. The following documentation is non-exhaustive, but should be enough for most uses.

Documentation

• Program

Value

Either Cons or Uint8Array.

Cons

A tuple of Program and Program.

Program

This represents a program or value in Chialisp or compiled clvm. It is the main class of the library, allowing you to manipulate programs and convert between various forms.

static true

• A program representing the value 1.

static false

• A program representing the value ().

atom

• The Uint8Array value of the program.

cons

• The Cons pair of the program.

first

• The first Program value of cons.

rest

• The rest Program value of cons.

isAtom

• A boolean for if it's an atom.

isCons

• A boolean for if it's a cons pair.

isNull

• A boolean for if it's null.

static cons(first, rest)

• first is a Program.
• rest is a Program.
• Returns a Program that is a cons pair between them.

static fromBytes(bytes)

• bytes is a Uint8Array.
• Returns a Program.

static fromHex(hex)

• hex is a hex string.
• Returns a Program.

static fromBool(value)

• value is a boolean.
• Returns a Program.

static fromInt(value)

• value is a number.
• Returns a Program.

static fromBigint(value)

• value is a bigint.
• Returns a Program.

static fromText(text)

• text is a string.
• Returns a Program.

static fromSource(source)

• source is a string.
• Returns a Program.

static fromList(programs)

• programs is an Array<Program>.
• Returns a Program.

static deserialize(bytes)

• bytes is a Uint8Array.
• Returns a Program.

constructor(value)

• value is a Value.

positionSuffix

• A string containing the line and column suffix, if there is one.

at(position)

• position is a Position.
• Returns this.

curry(args)

• args is an Array<Program>.
• Returns a Program containing the current one with each argument applied to it in reverse, precommitting them in the final solution.

uncurry()

• Returns a [Program, Array<Program>] containing the mod and curried in arguments.

hash()

• Returns a Uint8Array of the tree hash of the program. Hashed with 1 for atoms, and 2 for cons pairs.

hashHex()

• Returns a hex string representation of the tree hash.

define(program)

• Returns a Program containing the current one wrapped in a mod if there isn't already, and with a definition inserted.

defineAll(programs)

• programs is an Array<Program>.
• Returns a Program containing the current one and each definition.

compile(options?)

• options is a partial CompileOptions, defaulting to strict = false, operators = base, and includeFilePaths = {}.
• Returns a ProgramOutput that is the result of compiling the program. Should be identical to the run CLI tool.

run(environment, options?)

• environment is a Program.
• options is a partial RunOptions, defaulting to strict = false and operators = base.
• Returns a ProgramOutput that is the result of running the program. Should be identical to the brun CLI tool.

toBytes()

• Returns a Uint8Array representation.

toHex()

• Returns a hex string representation.

toBool()

• Returns a boolean representation.

toInt()

• Returns a number representation.

toBigInt()

• Returns a bigint representation.

toText()

• Returns a string representation.

toSource(showKeywords?)

• showKeywords is a boolean, by default true.
• Returns a string source code representation, like it would be if it were an output from run or brun.

toList(strict?)

• strict is a boolean, by default false.
• Returns an Array<Program> representation. If it's strict, it must be a proper list.

serialize()

• Returns a Uint8Array serialized form of the program.

serializeHex()

• Returns a hex string representation of the serialized form of the program.

equals(value)

• value is a Program.
• Returns a boolean for if the values are exactly equal.

toString()

• Returns a string source code representation, like it would be if it were an output from run or brun.
