# Unicode Text Formatter
An [Obsidian](https://obsidian.md) plugin that transforms selected text into Unicode Mathematical Alphanumeric Symbols — Sans-Serif Bold, Italic, and Bold-Italic — for use in LinkedIn and Facebook posts.
## Features
- **Unicode Bold** — converts letters and digits to sans-serif bold (𝗔𝗕𝗖 / 𝗮𝗯𝗰 / 𝟬𝟭𝟮)
- **Unicode Italic** — converts letters to sans-serif italic (𝘈𝘉𝘊 / 𝘢𝘣𝘤)
- **Unicode Bold Italic** — converts letters to sans-serif bold italic (𝘼𝘽𝘾 / 𝙖𝙗𝙘)
- Non-mapped characters (punctuation, spaces, emoji, etc.) are passed through unchanged
## Usage
1. Select text in the editor
2. Open the Command Palette (`Ctrl/Cmd + P`)
3. Run one of:
- **Format as Unicode Bold**
- **Format as Unicode Italic**
- **Format as Unicode Bold Italic**
The selected text is replaced in place with its Unicode equivalent.
## Installation
### Manual
1. Build the plugin (see [Development](#development)) or download a release
2. Copy `main.js` and `manifest.json` to your vault at:
```
<VaultFolder>/.obsidian/plugins/unicode-text-formatter/
```
3. In Obsidian: **Settings → Community Plugins → Installed Plugins** — enable **Unicode Text Formatter**
## Development
Requirements: Node.js ≥ 16
```bash
npm install
npm run dev # watch mode — recompiles on save
npm run build # one-time production build
npm run lint # ESLint check
```
### Project structure
| File | Purpose |
|------|---------|
| `src/unicode-maps.ts` | Builds character lookup maps from Unicode code point ranges |
| `src/formatter.ts` | `transformText(text, style)` — maps each character through the selected style map |
| `src/commands.ts` | Registers the three editor commands with the Obsidian plugin API |
| `src/main.ts` | Plugin entry point — calls `registerCommands` on load |
### Unicode blocks used
| Style | Uppercase | Lowercase | Digits |
|-------|-----------|-----------|--------|
| Sans-Serif Bold | U+1D5D4U+1D5ED | U+1D5EEU+1D607 | U+1D7ECU+1D7F5 |
| Sans-Serif Italic | U+1D608U+1D621 | U+1D622U+1D63B | — |
| Sans-Serif Bold-Italic | U+1D63CU+1D655 | U+1D656U+1D66F | — |
## Releasing
1. Update `manifest.json` with the new version and minimum Obsidian version
2. Update `versions.json`: `"new-version": "min-obsidian-version"`
3. Create a GitHub release tagged with the exact version number
4. Attach `manifest.json` and `main.js` as release assets
> You can bump the version automatically:
> ```bash
> npm version patch # or minor / major
> ```
