erago is a Go runtime/CLI for Emuera-style game files (.erb, .erh, .csv).

• Go 1.25+

Run directly from source:

go run ./cmd/erago -base ./era_files/1_adventure -entry TITLE

All build/deploy source assets are under build/:

• build/web/index.html: web runner UI
• build/web/main_js.go: wasm entry (js/wasm)
• build/mobile/bridge.go: gomobile bridge API

Use Makefile for build/release commands.

Build Linux/macOS/Windows binaries and web wasm bundle:

make build

Output artifacts:

• dist/linux-amd64/erago
• dist/linux-arm64/erago
• dist/darwin-amd64/erago
• dist/darwin-arm64/erago
• dist/windows-amd64/erago.exe
• dist/windows-arm64/erago.exe

./dist/linux-amd64/erago -base ./era_files/2_dialog_tool -entry TITLE

Run web build locally:

make serve-web

In the browser:

• add expected INPUT values to the queue
• click Run

Install gomobile (one-time):

go install golang.org/x/mobile/cmd/gomobile@latest

Build Android/iOS packages:

make mobile

Output artifacts:

• -base: base directory containing game files and save files
• -dir: deprecated alias of -base
• -entry: entry function (default: TITLE)

go run ./cmd/erago -h

• Save files are written to the same path as -base.
• cmd/erago writes SAVEVAR/SAVECHARA as Emuera-style binary .dat.
