# µFrame (Micronomicon)
A self-hosted web IDE and CLI for building rich terminal UIs using a declarative DSL. Compiles `.uf` source files into both plain ASCII art and styled Micron `.mu` pages for NomadNet — a decentralized communication platform running on the Reticulum mesh network.
## What It Does
Write this:
```
page "Node Status" 60
box double "Relay Alpha-7"
align center
text "Reticulum Network Node"
gauge "CPU" 62 100 28 warn=75 crit=90
status "East Relay" online
table "Routes"
columns "Dest" 20 | "Hops" 6 | "Status" 10
row "relay-east" | "2" | "@color{0f0}{alive}"
```
Get this (ASCII):
```
╔═ Relay Alpha-7 ════════════════════════════════════════════╗
║ Reticulum Network Node ║
╚════════════════════════════════════════════════════════════╝
CPU ████████████████████░░░░░░░░ 62%
● East Relay
┌────────────────────┬──────┬──────────┐
│Dest │Hops │Status │
├────────────────────┼──────┼──────────┤
│relay-east │2 │● alive │
└────────────────────┴──────┴──────────┘
```
And the same content as Micron `.mu` with color tags, bold, links, and interactive form fields — ready to serve on NomadNet.
## Quick Start
### Web IDE
```bash
# Backend
cd backend
source .venv/bin/activate
PAGES_DIR=~/.nomadnetwork/storage/pages \
SOURCES_DIR=~/.micron-editor/sources \
uvicorn main:app --reload --port 8080
# Frontend (separate terminal)
cd frontend
npm run dev
```
Open http://localhost:5173 → click **New Page** → click **Examples** → pick a template.
### CLI
```bash
cd backend
source .venv/bin/activate
# Render to terminal
python -m uframe render page.uf
# Render Micron only
python -m uframe render page.uf --micron
# Compile to .mu file
python -m uframe compile page.uf --out page.mu
# Validate without output
python -m uframe check page.uf
# Compile and deploy to NomadNet
python -m uframe deploy page.uf
```
## Tech Stack
| Layer | Technology |
|------------|-------------------------------------------------|

## API Endpoints
| Method | Path | Description |
|--------|---------------------|------------------------------------------------------|
| GET | /api/health | Health check |
| POST | /api/compile | Compile `.uf``{ascii, micron, script, is_dynamic}` |
| GET | /api/pages | List all pages with metadata |
| GET | /api/pages/{name} | Read page source |
| POST | /api/pages/{name} | Save page — `{ source, publish }` |
| DELETE | /api/pages/{name} | Delete source and/or .mu file |
| GET | /api/graph | Page link graph (nodes + edges) |
| POST | /api/restart | Restart NomadNet Docker container |
## Storage
```
~/.micron-editor/sources/ ← .uf source files (drafts + published)
~/.nomadnetwork/storage/pages/ ← Compiled .mu files served by NomadNet
```
- **Save Draft**: writes `.uf` to sources dir only
- **Publish (static)**: compiles `.uf``.mu`, writes to pages dir (chmod 644)
- **Publish (dynamic)**: compiles `.uf` → executable Python script, writes to pages dir (chmod 755)
NomadNet auto-detects the execute bit: static pages are served as-is, dynamic pages are executed and their stdout is served.
## µFrame DSL Reference
### Layout
```
page "Title" [width] # root (default width 64)
box [light|heavy|double|rounded] "Title" # bordered panel
row [gap] # horizontal layout
col [width] # column in a row
spacer [lines] # vertical whitespace
pad [t] [r] [b] [l] # inner margin
```
### Content
```
heading [1|2|3] "Text" # styled heading
text "Content with @bold{inline} @color{hex}{modifiers}"
label "Key" "Value" # aligned key-value pair
list [bullet|dash]
item "Entry"
link "Display text" "/dest.mu" # clickable in Micron
divider [light|heavy|double|dash|dot] # horizontal rule
# comment # ignored in output
```
### Data Visualization
```
gauge "Label" value max width [warn=N crit=N] # ████░░░░ bar with thresholds
sparkline "Label" "1,3,5,8,7,5" width # ⣀⣤⣶⣿⣷⣤ braille chart
status "Label" [online|offline|degraded] # ●○◐ colored indicators
table "Title"
columns "Name" 20 | "Hops" 6 | "Status" 10
row "relay" | "2" | "@color{0f0}{● alive}"
```
### Forms
```
form "name"
field "name" [width] "placeholder" # text input
password "name" [width] "placeholder" # masked input
radio "group" "Opt A" | "Opt B" | "Opt C" # radio buttons
checkbox "name" "Label" # checkbox
button "Label" "/action/path" # submit link
```
### Dynamic Features
```
cache 0 # never cache (re-execute)
source cpu : shell "cat /proc/loadavg" # live data at render time
source config : json "/path/config.json" # JSON file read
source ts : python "datetime.now().isoformat()" # Python expression
let name = "Relay Alpha" # variable assignment
if $cpu > 90
text "ALERT: CPU critical"
elif $cpu > 75
text "Warning: elevated"
for peer in $peers
status "$peer.name" $peer.state
on_submit "search"
source results : shell "search.py '$query'"
text "$results"
state "counter" "/tmp/counter.json" # persistent JSON store
```
### Components
```
# Define a reusable component
component stat(label, value, max)
gauge "$label" $value $max 20
# Use it
stat "CPU" 62 100
stat "MEM" 84 100
# Import standard library
use std/dashboard
banner "My Node" "Mesh Network"
resources 62 84
```
### Standard Libraries
| Library | Components |
|---------|-----------|
| `std/dashboard` | `banner(title, subtitle)`, `resources(cpu, mem)`, `peer_status(name, state)` |
| `std/status-bar` | `status_bar(label, value, max)`, `status_item(name, state)` |
| `std/nav` | `nav_link(label, dest)`, `nav_divider()` |
## Rendering Pipeline
```
.uf source
Parse ──→ IR Tree (30+ node types)
Measure (bottom-up: compute sizes)
Layout (top-down: assign positions)
Paint (depth-first: write chars into CharGrid)
Merge Borders (fix junction characters)
├──→ ASCII emitter → plain text
├──→ Micron emitter → styled .mu (with colors, links, form tags)
└──→ Codegen (if dynamic) → executable Python script
```
## Web IDE Features
- **Split-pane editor**: µFrame DSL source (left) / live preview (right)
- **Syntax highlighting**: keywords, strings, variables, comments in distinct colors
- **`/` command palette**: type `/` to insert layout, content, data viz, form, and style primitives
- **4 preview tabs**: ASCII | Micron (rendered) | Raw (Micron source) | Script (dynamic pages only)
- **`⚡ dynamic` badge**: auto-detected when source contains `source`, `if`, `for`, etc.
- **Examples dropdown**: 9 built-in templates (Hello World → Full Node Page → Dynamic Dashboard)
- **Pages dashboard**: table view with Published/Draft/Orphan status badges
- **Page graph**: React Flow visualization of inter-page links
- **Keyboard shortcuts**: `Ctrl+S` save draft, `Ctrl+P` publish
- **Unsaved changes guard**: warns before navigating away
- **Backlink indicator**: shows which pages link to the current page
## Running Tests
```bash
cd backend
source .venv/bin/activate
python -m pytest uframe/tests/ -v
```
42 tests covering:
- Static compilation (boxes, headings, text, gauges, tables, links, lists, spacers, dividers)
- Form elements (field, radio, checkbox, button)
- Dynamic pages (source, if/for, let, state, on_submit, codegen)
- Components (inline definitions, standard library, parameter substitution)
## Conventions
- µFrame engine is **pure Python stdlib** — zero external dependencies
- Backend is FastAPI; no ORM, flat file storage
- Frontend uses shadcn/ui components in `frontend/src/components/ui/`
- Feature components grouped by domain: `dashboard/`, `editor/`, `shared/`
- State management via Zustand stores
- All `.uf` sources stored in `SOURCES_DIR`, compiled `.mu` in `PAGES_DIR`
