9DE (early) + lib9deui

This repository is the starting point for a rio-based desktop shell on 9front.

Right now it ships:

• lib9deui: a small UI library (glass cards, primitives, basic widgets)
• ui9demo: a demo app proving the library links + draws

Next milestones (planned):

• lib9descene (in-window layer stack)
• lib9dewm (rio window manipulation helpers)
• 9bar / 9launch / 9notify + a 9de start script

Build

From the repo root:

mk

Run the demo

./cmd/ui-demo/ui9demo

Quit with Q.

Start 9DE (early)

./bin/9de-start.rc

Using lib9deui in your own program

Include + link

• Add include path: -I/path/to/9de/include
• Link: /path/to/9de/lib/lib9deui.a -ldraw -levent

Example include:

#include "9deui/9deui.h"

Minimal setup

Ui9 ui;
ui9init(&ui, display, font);
ui9setdst(&ui, screen);

draw(screen, screen->r, ui9img(&ui, Ui9CBg), nil, ZP);
ui9_card(&ui, Rect(20,20,320,120), 18);
ui9_shadowstring(&ui, Pt(40,50), "Hello 9DE");
flushimage(display, 1);

Install (optional, later)

When the API stabilizes you can install headers into /sys/include/9deui/ and the library into /sys/lib/. For now, keep it as a project-local SDK.

Components (early)

• 9de-session: session/config generator (cmd/9de-session)
• 9de-panel: top bar (cmd/9de-panel)

Repo-local start

chmod +x ./bin/9de-start.rc
