# Archway

`archway` is the lightweight command-line client for an Archway service.
It contains no translation engine, analysis engine, or server implementation.

## Installation

Install the command into an isolated environment:

```bash
pipx install archway
```

## Configuration

Set the service URL and personal bearer token:

```bash
export ARCHWAY_URL="https://your-archway-service.example.com"
export ARCHWAY_TOKEN="<personal token>"
```

The health check does not require a token:

```bash
archway health
```

Discover the installed client's current commands and agent guidance:

```bash
archway --help
archway agent-guide
archway capabilities --format json
```

Translate one Python file:

```bash
archway translate example.py
```

Specify its dotted module name and write the IR response to a file:

```bash
archway translate src/example.py \
  --module-name package.example \
  --output example.ir.json
```

## MCP server

Run a local stdio MCP adapter for agent hosts:

```bash
archway mcp serve
```

The MCP host launches this command as a child process. It exposes capability discovery,
service health, and Python translation tools backed by the same configured Archway Engine
Service as the CLI. It does not listen on a port or contain the engine itself.

The host must provide `ARCHWAY_URL` and `ARCHWAY_TOKEN` to the process. Do not put the
token in command arguments or commit it in a host configuration file.

Command output is JSON. Errors are written to standard error and do not include the
configured bearer token.

The installed client also provides an offline reference for the exact portable
categorical IR revision it supports:

```bash
archway ir schema --output portable-ir.schema.json
archway ir guide
archway ir definitions wire_expr
archway ir operations python.call
archway ir search "merge class"
```

These reference commands do not require `ARCHWAY_URL` or `ARCHWAY_TOKEN`.
The bundled revision-8 contract distinguishes class-body lexical captures
from names explicitly declared `global`; historical revisions require a
historical pinned client and service.

## What's new in 0.10.0

Portable categorical IR revision 8 is the sole current contract. It makes
Python class-scope declarations explicit by distinguishing lexical captures
from names declared `global`. It retains revision 7's effectful Python
protocol operations, faithful exception-handler dispatch, completion-flow
correlations, and corrected augmented-assignment and ordered call-argument
translation semantics.

```bash
archway translate example.py
archway ir guide
```

Use `--ir-format python-serde` only for a consumer that still requires the
legacy Python-specific serialization.

Revisions 3 through 7 are not supported by this release. Historical consumers
must use an Archway release pinned to the historical contract they require.
