Project
enka
A small macOS utility that maps left/right Command key single-taps to JIS Eisu and Kana input-source keys.
enka is an Ultrahope project for people who switch between Japanese and English input all day and want that motion to stay close to their hands. A left Command single-tap posts the JIS Eisu key event, and a right Command single-tap posts the JIS Kana key event.
The scope is intentionally narrow. enka is not a general command launcher; it watches Command releases, cancels when another key is pressed, and posts the input-source key events directly with CGEvent.
It ships as a Swift CLI plus Enka.app for the macOS Accessibility permission identity. The hosted installer installs the binary and app bundle, writes the LaunchAgent, opens the permission flow, waits for approval, and starts the daemon once macOS allows it.
