# Overview

Core is an opinionated framework for building Go desktop apps with Wails, providing a small set of focused modules you can mix into your app. It ships with sensible defaults and a demo app that doubles as in‑app help.

## Modules

- Core — framework bootstrap and service container
- Core.Config — app and UI state persistence
- Core.Crypt — keys, encrypt/decrypt, sign/verify
- Core.Display — windows, tray, window state
- Core.Docs — in‑app help and deep‑links
- Core.IO — local/remote filesystem helpers
- Core.Workspace — projects and paths

## Quick start
```go
package main

import (
    core "github.com/Snider/Core"
)

func main() {
	app := core.New(
		core.WithServiceLock(),
	)
	_ = app // start via Wails in your main package
}
```

## Services
```go
package demo

import (
    core "github.com/Snider/Core"
)

// Register your service
func Register(c *core.Core) error {
	return c.RegisterModule("demo", &Demo{core: c})
}
```

## Display example
```go
package display

import (
    "context"
    "github.com/wailsapp/wails/v3/pkg/application"
)

// Open a window on startup
func (d *API) ServiceStartup(ctx context.Context, _ application.ServiceOptions) error {
	d.OpenWindow(
		OptName("main"),
		OptHeight(900),
		OptWidth(1280),
		OptURL("/"),
		OptTitle("Core"),
	)
	return nil
}
```
