# AGENTS.md — AKAI Utils Development Guide
|
|
|
|
## Toolchain (mise)
|
|
|
|
```bash
|
|
mise trust # trust the mise.toml config (first time only)
|
|
mise install # installs go 1.26, node 22
|
|
```
|
|
|
|
All build/run tasks are defined in `mise.toml`:
|
|
|
|
```bash
|
|
mise run build # → ./fetch
|
|
mise run serve # → starts HTTP server, opens browser
|
|
mise run electron-deps # installs electron + electron-builder
|
|
mise run electron-dev # runs electron in dev mode
|
|
mise run docker-up # docker compose up --build
|
|
mise run lint # go vet ./...
|
|
mise run check-all # verify gcc, brew, mise, go, node, docker, colima
|
|
```
|
|
|
|
## Build & Run (manual)
|
|
|
|
```bash
|
|
# Build Go binary (zero CGO)
|
|
go build -buildvcs=false -o fetch . # → ./fetch
|
|
|
|
# Build and run web server
|
|
./fetch serve # → starts on free port, opens browser
|
|
./fetch serve --host 0.0.0.0 -p 8080 # → Docker / network-accessible mode
|
|
|
|
# Docker
|
|
docker compose up --build # serves on :8080, binds 0.0.0.0
|
|
|
|
# Electron dev
|
|
(cd electron && npm install)
|
|
(cd electron && npx electron .)
|
|
|
|
# Cross-compile for macOS (from Linux)
|
|
GOOS=darwin GOARCH=arm64 go build -o fetch-darwin-arm64 .
|
|
GOOS=darwin GOARCH=amd64 go build -o fetch-darwin-amd64 .
|
|
```
|
|
|
|
## Architecture
|
|
|
|
Single binary (`fetch`) with subcommands. No external Go dependencies — pure stdlib.
|
|
|
|
```
|
|
main.go CLI entry, commands (search/list/download/extract/pipeline/serve)
|
|
serve.go HTTP server + REST API + embedded web UI (embed.FS)
|
|
web/ui/ Static frontend (index.html, style.css, app.js)
|
|
electron/ Electron wrapper shell
|
|
scripts/ Bash helpers called via exec
|
|
├── extract_wavs.sh batch WAV extraction via akaiutil
|
|
├── check-toolchain.sh verify gcc, brew, mise, go, node
|
|
└── check-docker-toolchain.sh verify docker, compose, colima
|
|
third_party/ Vendored akaiutil C binary (GPLv2)
|
|
```
|
|
|
|
### Key patterns
|
|
|
|
- **Subcommand dispatch**: `main.go:60` — switch on `os.Args[1]`, each case calls `cmdXxx(args)`
|
|
- **Flag parsing**: each command creates its own `flag.NewFlagSet` — avoids global flag state
|
|
- **Concurrency**: semaphore channel pattern (`sem := make(chan struct{}, N)`) for bounded parallelism
|
|
- **SSE progress**: `serve.go:handleProgress` — 500ms ticker, EventSource stream, auto-closes when all done
|
|
- **Script discovery**: `serve.go:findScript()` — tries multiple candidate paths, fallback chain
|
|
- **Zero-deps web UI**: vanilla JS, no bundler, no framework. API calls use `fetch()` + `EventSource`
|
|
- **Embed directive**: `//go:embed web/ui/*` in `serve.go` — frontend baked into the binary
|
|
- **Bind address handling**: `serve.go:37` — `--host` flag defaults to `127.0.0.1` for local dev; set `--host 0.0.0.0` for Docker. When binding to `0.0.0.0`, prints both `localhost` and `<host-ip>` URLs for clarity.
|
|
|
|
### akaiutil integration
|
|
|
|
`scripts/extract_wavs.sh` shells out to `akaiutil` for:
|
|
- `df` — disk info (partitions, block counts)
|
|
- `dir` — list volumes/files
|
|
- `sample2wavall` — batch WAV extraction
|
|
- Many more commands available (see `docs/akaiutil.md`)
|
|
|
|
All akaiutil calls use `-r` (read-only) flag. Write operations (S900 compress, partitioning, tagging) require removing `-r`.
|
|
|
|
### macOS compatibility
|
|
|
|
- `third_party/akaiutil/commoninclude.h` has `bcopy`/`bzero` declarations guarded with `#ifdef _VISUALCPC` to avoid conflicts with macOS system headers that define these in `<strings.h>`.
|
|
|
|
### Electron integration
|
|
|
|
`electron/main.js` spawns the Go binary in `serve` mode:
|
|
1. Finds `fetch` binary next to app or in `process.resourcesPath`
|
|
2. Spawns `fetch serve -p 0 --no-browser`
|
|
3. Parses `stdout` for `Local: http://localhost:XXXX` to get port
|
|
4. Creates `BrowserWindow` pointing at that URL
|
|
5. Kills server on quit
|
|
|
|
## Adding a new feature
|
|
|
|
1. **New API endpoint**: add handler in `serve.go`, register in `cmdServe` mux
|
|
2. **New web UI section**: add HTML in `index.html`, CSS in `style.css`, JS in `app.js`
|
|
3. **New akaiutil wrapper**: create a bash script in `scripts/` or call akaiutil directly via `exec.Command` in Go
|
|
4. **New CLI subcommand**: add case in `main.go:60`, implement `cmdXxx(args)` function
|
|
|
|
### API conventions
|
|
|
|
- All responses have `Content-Type: application/json` and `Access-Control-Allow-Origin: *`
|
|
- Use `writeJSON(w, v)` for responses, it sets headers and marshals
|
|
- Download progress uses SSE (`text/event-stream`) with `data: <json>\n\n`
|
|
- Error responses use `http.Error(w, msg, code)` or return JSON with `"error"` key
|
|
|
|
## Format conventions
|
|
|
|
- Go: standard `gofmt` (no custom formatter)
|
|
- Bash: `set -euo pipefail`, shellcheck-compatible
|
|
- JS: no semicolons (ASI style), `const` preferred over `let`
|
|
- CSS: CSS custom properties for theming (`:root { --bg: ... }`)
|
|
|
|
## Testing
|
|
|
|
No test framework yet. Manual verification:
|
|
```bash
|
|
go build -o /dev/null . # compile check
|
|
./fetch serve # manual smoke test
|
|
```
|
|
|
|
## Secrets & Tokens
|
|
|
|
None required. archive.org API is public and unauthenticated.
|
|
AKAIUTIL environment variable controls the akaiutil binary path.
