Ethos DevTools Extension

Ethos DevTools flyingeek.ethos-devtools is a VS Code extension that complements the bsongis.ethos extension.

The extension is only activated in workspaces where the bsongis.ethos extension is active. It requires bsongis.ethos to be installed.

Features

Deploy to Simulator

This is the main feature of the extension, it makes working on your project easier by copying a Lua app folder from the workspace into the Ethos simulator's scripts directory, with optional manifest-driven selective copy and pre/post-deploy steps. See Deploy to Simulator.

Log Colorization

Colorizes Ethos log files — errors, warnings, Lua script errors, Lua::method calls, and simulator start/stop events are each highlighted distinctly. See Log Colorization.

Telemetry Playback

Replay a CSV telemetry log (Ethos or EdgeTX format) into the running simulator and pin a status label. Inject individual sensor values on demand. See Telemetry Commands.

Deploy to Radio

Deploy a Lua app folder to a connected radio over USB, in several sync modes. See Deploy to Radio. This can be useful for testing on a real radio at the last stage of development.

Scaffold New Project

Scaffold a new Lua project from a GitHub template repository, with interactive prompts and template variable substitution. See Project Scaffolding.

Main commands

Command	Description
Ethos DevTools: Play Telemetry CSV	Replay a CSV telemetry log into the running simulator
Ethos DevTools: Stop Telemetry	Stop playback and clear the pinned status label
Ethos DevTools: Set Telemetry Value	Inject a single sensor value into the running simulator
Ethos DevTools: Deploy to Simulator	Copy a Lua app to the simulator scripts directory
Ethos DevTools: Deploy to Radio	Deploy a Lua app to a connected radio
Ethos DevTools: Scaffold New Project	Scaffold a new Lua project from a GitHub template

Installation

Install the extension from the VS Code marketplace: flyingeek.ethos-devtools

The extension uses native dependencies for radio connection features, so platform-specific VSIX files are provided for Windows (x64), Linux (x64), and macOS (arm64 and x64). The Linux version has not been fully tested — raise an issue if you encounter problems.

For other platforms, a universal build is available without native dependencies; radio connection features will not work, but everything else will.

VSIX files can also be downloaded from the releases page of the GitHub repository. To install a VSIX file, open the Extensions view, click the three-dot menu, select Install from VSIX…, and choose the file (or drag and drop it into the Extensions view).

Main Configuration

Setting	Type	Description
ethos-devtools.deploy	object	Configuration for Deploy to Simulator and Deploy to Radio. See Deploy to Simulator.
ethos-devtools.reload	object	Configuration for Ethos DevTools: Reload Simulator. Same syntax as ethos-menu.json. Defaults to { "command": ["ethos.stop", "ethos-devtools.deploySimulator", "ethos.start"] }.

The minimum deploy configuration to add to your .vscode/settings.json file is:

"ethos-devtools.deploy": {
    "app": "appname"
}

But that is only valid for a single app layout. See Project Structure for more information.

ethos-menu.json

To integrate with the Ethos extension's menu, add entries to your project's ethos-menu.json:

[
    {
        "label": "📊 Telemetry playback",
        "command": "ethos-devtools.playTelemetry"
    },
    {
        "label": "✏️ Set telemetry value",
        "command": "ethos-devtools.setTelemetry"
    },
    {
        "label": "🚀 Deploy to simulator",
        "command": "ethos-devtools.deploySimulator"
    },
    {
        "label": "📻 Deploy to radio",
        "command": "ethos-devtools.deployRadio"
    },
    {
        "label": "$(debug-start)Deploy & Launch SIM",
        "command": "ethos-devtools.reload"
    }
]
