Remove the dedicated `zig build lib-vt` step and replace it with a `-Demit-lib-vt` build option. This fixes two problems: 1. We can default XCFramework, app, etc. steps to false if emit-lib-vt is true, so that the lib-vt build doesn't pull in unrelated artifacts. **Most importantly, lib-vt alone can be build without full Xcode installations.** 2. We can build lib-vt as part of a bundle with other artifacts if we really want.

# WebAssembly Key Encoder Example
|
|
|
|
This example demonstrates how to use the Ghostty VT library from WebAssembly
|
|
to encode key events into terminal escape sequences.
|
|
|
|
## Building
|
|
|
|
First, build the WebAssembly module:
|
|
|
|
```bash
|
|
zig build -Demit-lib-vt -Dtarget=wasm32-freestanding -Doptimize=ReleaseSmall
|
|
```
|
|
|
|
This will create `zig-out/bin/ghostty-vt.wasm`.
|
|
|
|
## Running
|
|
|
|
**Important:** You must serve this via HTTP, not open it as a file directly.
|
|
Browsers block loading WASM files from `file://` URLs.
|
|
|
|
From the **root of the ghostty repository**, serve with a local HTTP server:
|
|
|
|
```bash
|
|
# Using Python (recommended)
|
|
python3 -m http.server 8000
|
|
|
|
# Or using Node.js
|
|
npx serve .
|
|
|
|
# Or using PHP
|
|
php -S localhost:8000
|
|
```
|
|
|
|
Then open your browser to:
|
|
|
|
```
|
|
http://localhost:8000/example/wasm-key-encode/
|
|
```
|
|
|
|
Focus the text input field and press any key combination to see the encoded output.
