ZapAlert is a Visual Studio Code extension that provides audio alerts for command success or errors in the integrated terminal. It is designed to improve developer productivity by providing immediate feedback without constantly monitoring the terminal output.
Features
Detects a wide range of common terminal errors including syntax errors, runtime errors, missing modules, permission issues, and command not found messages.
Plays distinct audio alerts for first and repeated errors.
Plays a success sound when commands complete successfully or tests/builds pass.
Plays a success sound when the terminal is cleared.
Works exclusively in the VS Code integrated terminal (bash/zsh on macOS).
Handles rapid output with a debounce mechanism to prevent overlapping audio.
Lightweight, with no additional configuration required.
Workflow
Open the integrated terminal in VS Code (Ctrl+` on macOS).
Run any command or script.
ZapAlert monitors terminal output in real time:
Error detection: Plays an alert sound on error; repeated errors trigger a different sound.
Success detection: Plays a success sound when commands/tests/builds succeed.
Clear detection: Plays a success sound when you run clear.
Note: ZapAlert does not work in external system terminals outside VS Code.
