actr-cli

中文 | English

actr-cli is the command line tool for Actor-RTC framework projects. It bootstraps projects, manages service dependencies, discovers services on the network, and generates code from Protocol Buffers definitions.

Status and limitations

• The CLI entrypoint exposes: init, install, discovery, gen, and check.
• init (Rust and Swift) and gen are functional today.
• install and discovery depend on service components that are not registered in ContainerBuilder::build, so they will fail with "not registered" errors until the container wiring is implemented.
• check in src/main.rs is a placeholder implementation.
• Python and Kotlin init/codegen are not implemented yet.

Requirements

• Rust 1.88+ and Cargo
• protoc in PATH
• rustfmt in PATH (skip with actr gen --no-format)

Rust codegen:

• protoc-gen-prost in PATH (used by --prost_out)
• protoc-gen-actrframework in PATH
  • If missing, actr gen attempts to build and install it from an Actr workspace that contains crates/framework-protoc-codegen.

Swift init/codegen:

• protoc-gen-swift
• protoc-gen-actrframework-swift
• xcodegen
• project.yml present in the project root for xcodegen generate

Install (from source)

cargo build --release

Or install the binary into your Cargo bin directory:

cargo install --path .

Quick start

Create a Rust project:

actr init my-service --signaling ws://127.0.0.1:8080
cd my-service
actr gen

Create a Swift project (template: echo only):

actr init my-app --signaling ws://127.0.0.1:8080 --language swift --template echo

Commands

actr init

Initialize a new project. If required fields are missing, the command will prompt interactively.

Flags:

• --template <name>: project template (Swift supports echo only)
• --project-name <name>: project name when initializing in the current directory
• --signaling <url>: signaling server URL (required)
• -l, --language <rust|python|swift|kotlin>: target language (default: rust)

Examples:

# New directory
actr init my-service --signaling ws://127.0.0.1:8080

# Current directory
actr init . --project-name my-service --signaling ws://127.0.0.1:8080

# Swift
actr init my-app --signaling ws://127.0.0.1:8080 -l swift --template echo

actr install

Install service dependencies from Actr.toml or add new dependencies by package spec.

Flags:

• --force: reserved (not wired yet)
• --force-update: reserved (not wired yet)
• --skip-verification: reserved (not wired yet)

Examples:

# Install dependencies listed in Actr.toml
actr install

# Add a dependency
actr install actr://user-service@1.0.0/

actr discovery

Discover services on the network and optionally add them to Actr.toml. This command is interactive and will prompt for selection and actions.

Flags:

• --filter <pattern>: service name filter (e.g. user-*)
• --verbose: reserved (not wired yet)
• --auto-install: install the selected service without prompting

Example:

actr discovery --filter user-*

actr gen

Generate code from proto files.

Flags:

• -i, --input <path>: input proto file or directory (default: proto)
• -o, --output <path>: output directory (default: src/generated)
• --clean: remove the output directory before generating
• --no-scaffold: skip user code scaffold generation
• --overwrite-user-code: overwrite existing user code files
• --no-format: skip rustfmt
• --debug: keep intermediate generated files
• -l, --language <rust|python|swift|kotlin>: target language (default: rust)

Examples:

# Rust (defaults)
actr gen

# Rust with explicit paths
actr gen -i proto -o src/generated

# Swift
actr gen -l swift -i protos/echo.proto -o MyApp/Generated

Notes:

• Rust codegen runs rustfmt and cargo check automatically unless --no-format is set.
• Generated Rust files are set to read-only after generation.
• Swift codegen runs xcodegen generate and requires project.yml.
• Python/Kotlin generators are placeholders and do not emit code yet.

actr check

The CLI currently exposes a placeholder check command that prints the provided flags. The full CheckCommand implementation exists in src/commands/check.rs but is not wired into the CLI entrypoint yet.

Configuration (Actr.toml)

Actr.toml is used by multiple commands (notably install and gen) and should define the Actor type under [package.actr_type].

Minimal example:

edition = 1
exports = []

[package]
name = "example-service"
description = "An Actor-RTC service"

[package.actr_type]
manufacturer = "acme"
name = "example-service"

[dependencies]
# "acme+other-service" = {}

[system.signaling]
url = "ws://127.0.0.1:8080"
