# EVA ICS v4 Local Service Launcher

Local service launcher for [EVA ICS v4](https://www.eva-ics.com) industrial
automation platform.

Allows to run and test EVA ICS services locally.

More info about EVA ICS Rust SDK: <https://info.bma.ai/en/actual/eva4/sdk/rust/index.html>

## Installation

```bash
cargo install eva-lsl
```

## Usage

### Creating a basic service

```bash
eva-lsl new myservice
```

### Testing a service

* Deploy the service configuration to a EVA ICS node. The service can be
  disabled and point to any non-existing command.

* Allow remote connections to the node (`eva edit config/bus`). If a node is
  installed on the same machine, skip this step.

* Inside a Rust service project, run:

```bash
eva-lsl run -b IP:PORT SVC_ID
```

(for a local node but non-standard path, specify path to `bus.ipc`)

The command builds the service and run it locally, connecting to the node bus.
Log messages are printed to the local console.

Use `--watch` (or `-w`) to automatically rebuild the service on source code
changes.

The command can also override, the service bus id, user, data path etc. Check
other options with `eva-lsl --help`.
