A2UI CLI developer tool and typesafe component generator.

A2UI CLI

Developer tool and typesafe component generator for A2UI catalogs.

Installation

Standalone Pre-Built Binaries

Pre-built standalone executables are available for official release tags (beginning with cli-v0.1.0). No Dart or Flutter SDK installation is required.

macOS & Linux (curl)

curl -fsSL https://raw.githubusercontent.com/a2ui-project/a2ui/main/scripts/public/install_cli.sh | sh

The script automatically detects your platform (macOS Apple Silicon/Intel, Linux x86_64/ARM64), verifies the cryptographic SHA-256 checksum against official release assets, and installs a2ui into ${XDG_BIN_HOME:-~/.local/bin} (or $A2UI_INSTALL_DIR, with optional version pinning via $A2UI_VERSION) without requiring sudo.

Windows (PowerShell)

irm https://raw.githubusercontent.com/a2ui-project/a2ui/main/scripts/public/install_cli.ps1 | iex

Verifies the cryptographic SHA-256 checksum against official release assets, installs a2ui.exe into %LOCALAPPDATA%\Programs\a2ui\bin (or $env:A2UI_INSTALL_DIR, with optional version pinning via $env:A2UI_VERSION), and ensures it is added to the user's PATH.

Running from Source (Dart SDK)

Run directly using dart:

dart run dart/a2ui_cli/bin/a2ui.dart codegen \
  --catalog path/to/catalog.json \
  --out path/to/output_dir/

Or activate globally from source:

dart pub global activate --source path dart/a2ui_cli
a2ui codegen -c path/to/catalog.json -o path/to/output_dir/

Regenerating Checked-In Python Builders

After changing the generator or a basic catalog schema, regenerate the Python SDK builder catalog using:

# Protocol v0.9 / v0.9.1:
dart run dart/a2ui_cli/bin/a2ui.dart codegen \
  --catalog specification/v0_9_1/catalogs/basic/catalog.json \
  --out python/a2ui_agent/src/a2ui/builder/v0_9/catalogs/basic.py

# Protocol v1.0:
dart run dart/a2ui_cli/bin/a2ui.dart codegen \
  --catalog catalogs/basic/v1/catalog.json \
  --out python/a2ui_agent/src/a2ui/builder/v1_0/catalogs/basic.py
