# Micronomicon
# µFrame (Micronomicon)
A self-hosted web editor for writing Markdown and publishing `.mu` pages to a NomadNet node.
A declarative DSL and web IDE for building rich terminal UIs that publish as `.mu` pages to [NomadNet](https://github.com/markqvist/NomadNet) — a decentralized communication platform on the [Reticulum](https://github.com/markqvist/Reticulum) mesh network.
Write in Markdown → preview as Micron → publish directly to `~/.nomadnetwork/storage/pages/`.
Write structured layouts with box-drawing, gauges, tables, and forms in a simple DSL. Get both plain ASCII art (viewable in any terminal) and styled Micron markup (with colors, links, and interactive form fields) from the same source.
```

## Requirements
## Quick Start
- Docker + Docker Compose
- Python 3.13+ (for local backend development only)
- Node 20+ (for local frontend development only)
- A running NomadNet container named `nomadnet` (for the restart button)
---
## Quick Start (Docker)
### Web IDE
```bash
# 1. Build the frontend
cd frontend
npm install
npm run build
cd ..
# 2. Create source directories
# 1. Create directories
mkdir -p ~/.nomadnetwork/storage/pages ~/.micron-editor/sources
# 3. Start the stack
docker compose up --build
```
App is available at `http://localhost:8080`.
### Tailscale HTTPS
```bash
tailscale serve --bg https+insecure://localhost:8080
```
---
## Local Development
Run backend and frontend separately with hot reload.
**Backend**
```bash
# 2. Backend
cd backend
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt
PAGES_DIR=~/.nomadnetwork/storage/pages \
SOURCES_DIR=~/.micron-editor/sources \
uvicorn main:app --reload --port 8080
```
**Frontend**
```bash
# 3. Frontend (separate terminal)
cd frontend
npm install
npm run dev # proxies /api → localhost:8080
npm run dev
```
Open `http://localhost:5173`.
Open http://localhost:5173**New Page****Examples** → pick a template.
### CLI
```bash
cd backend && source .venv/bin/activate
python -m uframe render page.uf # ASCII to stdout
python -m uframe render page.uf --micron # Micron to stdout
python -m uframe compile page.uf # → page.mu
python -m uframe check page.uf # validate
python -m uframe deploy page.uf # compile + copy to NomadNet pages
```
### Docker
```bash
cd frontend && npm install && npm run build && cd ..
docker compose up --build
```
App at http://localhost:8080. Add Tailscale: `tailscale serve --bg https+insecure://localhost:8080`

## DSL Overview
### Layout
```
page "Title" [width] # root container
box [light|heavy|double|rounded] "Title" # bordered panel
row [gap] # horizontal split
col [width] # column
spacer [lines] # vertical space
```
### Content
```
heading [1|2|3] "Text" # heading
text "Hello @bold{world} @color{0f0}{green}" # text with inline modifiers
label "Key" "Value" # key-value pair
link "Click me" "/page/dest.mu" # clickable link
divider [light|heavy|double] # horizontal rule
```
### Data Visualization
```
gauge "CPU" 62 100 28 warn=75 crit=90 # ████████░░░░ 62%
sparkline "Net" "1,3,5,8,7,5" 20 # ⣀⣤⣶⣿⣷⣤ braille chart
status "Server" [online|offline|degraded] # ●○◐ indicator
table "Routes"
columns "Dest" 20 | "Hops" 6
row "east" | "2"
```
### Forms
```
form "search"
field "query" 30 "Search..." # text input
radio "scope" "Local" | "Network" # radio buttons
checkbox "cache" "Include cached" # checkbox
button "Go" "/page/search.mu" # submit
```
### Dynamic Pages
```
cache 0 # re-execute on every request
source cpu : shell "cat /proc/loadavg" # live data
if $cpu > 90
text "ALERT"
for peer in $peers
status "$peer.name" $peer.state
state "visits" "/tmp/visits.json" # persistent store
```
### Components
```
component stat(label, value, max)
gauge "$label" $value $max 20
stat "CPU" 62 100 # reuse
use std/dashboard # import standard library
banner "My Node" "Mesh Network" # use library component
```

## Architecture
```
.uf source → Parse → IR Tree → Measure → Layout → Paint → CharGrid
├→ ASCII (plain text)
├→ Micron (.mu with styles)
└→ Script (dynamic: executable Python)
```
**Static pages**: `.uf` compiles to `.mu` (Micron markup). NomadNet serves the file directly.
**Dynamic pages**: `.uf` with `source`/`if`/`for` compiles to an executable Python script. NomadNet detects the `+x` bit, runs the script on each request, and serves the stdout as Micron. Live system data, form handling, and state persistence all work through this model.

## API
| Method | Path | Description |

| 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 `{source, publish}` — draft or publish |
| DELETE | /api/pages/{name} | Delete page |
| GET | /api/graph | Page link graph |

- **`/` command palette** — type `/` to insert any DSL primitive
- **4 preview tabs** — ASCII | Micron (rendered) | Raw | Script (dynamic only)
- **Examples dropdown** — 9 templates from Hello World to Dynamic Dashboard
- **Pages dashboard** with Published / Draft / Orphan status badges
- **Page graph** — React Flow visualization of inter-page links
- **Keyboard shortcuts** — `Ctrl+S` save, `Ctrl+P` publish
- **Backlink indicator** — shows which pages link to the current page

## Page Lifecycle
## References
```
New Page → /editor/new → Save Draft → .md saved to sources/
→ Publish → .md saved + .mu written to pages/
```
- **Draft** — `.md` exists, no `.mu`. Not visible on NomadNet.
- **Published** — both `.md` and `.mu` exist.
- **Orphan** — `.mu` exists but no `.md` source (e.g. pages created outside this tool).

## Known Limitations (Phase 1)
- Micron preview is plain text — full terminal rendering comes in a later phase (micron-parser-js iframe)
- `[[` link autocomplete not yet implemented (Phase 2)
- Graph view is read-only; click a node to open it in the editor
- No metrics (Phase 4)
- [NomadNet](https://github.com/markqvist/NomadNet) — decentralized communication
- [Reticulum](https://github.com/markqvist/Reticulum) — mesh networking stack
- [Micron syntax](https://github.com/fr33n0w/micron-composer) — markup reference
