programming language
For brokers

An experimental techniques language that gives structured diagnostics to AI brokers,
Accommodates typed restore metadata and machine-readable documentation with lower than 10 KiB of native binaries.

Agent restore loop challenge

Most programming languages ​​produce compiler output written for human readers. That is unstructured textual content that the AI ​​agent should parse to find out what went improper and the best way to repair it. This creates a fragile loop.

• agent writes code — the compiler outputs the error as unstructured textual content
• Agent parses textual content — Error format could differ between compiler variations
• No restore ideas — No idea of “restore motion” in-built
• human historical past — Loop requires handbook intervention to resolve error

Zero was designed from the bottom as much as enable brokers to learn code, interpret diagnostics, and restore packages with out human translation.

03 / 09 · JSON diagnostics

Structured compiler output

working zero test ——json Outputs machine-readable diagnostics as a substitute of plain textual content. All errors embrace secure code, human message, line quantity, and restore ID entered.

$ zero test --json
{
  "okay": false,
  "diagnostics": [{
    "code": "NAM003",
    "message": "unknown identifier",
    "line": 3,
    "repair": { "id": "declare-missing-symbol" }
  }]
}

• code — Secure identifier brokers can reliably match (NAM003)
• message — Human-readable error description
• restore — Entered remediation ID agent can work with out textual content parsing

core performance
04 / 09 · Restore command

Zero explanations, zero corrections

Two CLI subcommands full the agent restore loop with out the agent having to parse the prose doc.

zero clarify NAM003

zero repair --plan --json add.0

collectively, zero clarify and zero repair --plan --json Allow brokers to grasp errors and act on them with out human translation of compiler output.

05/09 · Agent steerage

Zero talent: version-specific agent steerage

Most instruments require the agent to gather exterior documentation that could be out of sync with the put in compiler. Zero solves this like this zero abilities — Steering offered instantly from the CLI relying on the put in model.

zero abilities get zero --full

Returns a workflow centered on:

• zero syntax — Fundamentals of the present model of the language
• analysis — Easy methods to interpret and course of compiler output
• construct and package deal — Manifest construction, targets, and outputs
• Check and agent edit loop — Validation and remediation workflow sample

language design
06 / 09 · Characteristic-based I/O

Specific results and feature-based I/O

In Zero, when a operate touches the surface world, its signature signifies that. There aren’t any hidden international course of objects, implicit asyncs, and magic globals.

pub enjoyable foremost(world: World) -> Void raises {
  test world.out.write("hiya from zeron")
}

• World: World — Purposeful object; permits entry to I/O, file system, community
• test — Deal with incorrect operations. Floor failures as much as the decision stack
• improve — marks the operate as probably propagating errors — seems within the signature
• compile-time enforcement — Unavailable options are rejected at compile time, not at run time.

07 / 09 · Reminiscence and measurement

Predictable reminiscence and small binaries

Zero targets environments the place binary measurement and reminiscence predictability are necessary. There aren’t any hidden runtime taxes.

zero construct --emit exe 
  --target linux-musl-x64 
  add.0 --out .zero/out/add

• zero measurement --json — Report the scale of artifacts earlier than code era if doable
• no hidden allocators — Assignments are specific and visual within the code
• C ABI export — C boundary target-aware interop metadata

08 / 09 · Introduction

Set up and run Zero

Set up the compiler with a single curl command.

curl -fsSL https://zerolang.ai/set up.sh | bash
export PATH="$HOME/.zero/bin:$PATH"
zero --version

Confirm, run, and construct your first program.

zero test examples/hiya.0
zero run   examples/add.0
zero construct --emit exe --target linux-musl-x64 
  examples/add.0 --out .zero/out/add

Create a brand new package deal.

zero new cli hiya
cd hiya
zero test .  &&  zero check .  &&  zero run .

state of affairs
09 / 09 · Present state of affairs

What can and can’t be used

• v0.1.1 (experimental) — Compiler, stdlib, and language specs will not be but secure
• package deal registry lacking — Ecosystem unfold is in its early phases
• cross compilation — restricted to a subset of documented targets
• VS Code extensions — syntax highlighting .0 The file will probably be included within the repository
• contributor — Chris Tate & Matt Van Horn (Vercel Labs)

Zero is a sensible experiment value following for AI engineers concerned about agent-native toolchain design, and isn’t but production-agnostic.
