# NorgUI
NorgUI provides themable SwiftUI views to render `.norg` / [Neorg](https://github.com/nvim-neorg/neorg) documents
parsed with [NorgKit](https://git.sr.ht/~rbdr/norgkit).
`NorgUI` doesn't provide editing capabilities.
## Installation
Add the package with Xcode package manager: `https://git.r.bdr.sh/norgui`, and
depend on `NorgUI` from your target.
## Usage
Parse a document with `NorgKit` and render it with `NorgView`:
import SwiftUI
import NorgKit
import NorgUI
```swift
struct NoteView: View {
let source: String
var body: some View {
ScrollView {
NorgView(document: NorgParser.parse(source)) { line, status in
// Persist the new status back to your file at `line`.
}
.padding()
}
}
}
```
The `onSetStatus` callback is optional (defaults to a no-op) and fires when the
user taps or long-presses a task's status symbol, reporting the source `line`
and the chosen `TaskStatus`.
### Links
Links are handled via an `onOpenLink` optional callback which will give you the
`InlineLink`. If you don't provide one, external links will be handled by the
system, while internal links and anchors will be inert.
```swift
NorgView(document: document) { link in
switch link.target {
case let target? where target.hasPrefix("http"): openURL(URL(string: target)!)
default: scrollTo(target: link.target) // a heading/anchor in this document
}
}
```
### Collapsible View
Pass `collapsible: true` to render the document as a tree of `DisclosureGroup`s.
Headings collapse their content, nested lists and quotes collapse their
children, and definitions/footnotes/table cells collapse their body. Each
section manages its own expand/collapse state and starts expanded.
```swift
NorgView(document: NorgParser.parse(source), collapsible: true)
```
### Tasks
You can render tasks independently (eg. if you got them via `TaskScanner`) with
`NorgTaskView`.
```swift
NorgTaskView(
status: task.status,
text: AttributedString(task.text),
onToggle: { setStatus(task, .done) },
onSetStatus: { setStatus(task, $0) }
)
```
## Theming
Fonts and colors can be changed by creating a `NorgTheme` and using the
`.norgTheme` modifier.
```swift
var theme = NorgTheme.default
theme.linkColor = .purple
theme.heading = { level in level == 1 ? .largeTitle.bold() : .title2 }
theme.statusSymbol = { $0 == .done ? "checkmark.square.fill" : "square" }
NorgView(document: document)
.norgTheme(theme)
```
Note: `AttributedString(norg:)` can't read the environment, so you need to pass
the theme explicitly if you build text outside the views.
```swift
let styled = AttributedString(norg: spans, theme: theme)
```
### NorgTheme API
| Property | Type | Default | Styles |
| --- | --- | --- | --- |
| `heading` | `(Int) -> Font` | `.title.bold()` (lvl 1) down to `.subheadline` | Heading text, per level |
| `body` | `Font` | `.body` | Paragraphs, list items, quotes |
| `termFont` | `Font` | `.body.bold()` | Definition / footnote / table-cell titles |
| `verbatimColor` | `Color` | `.pink` | `verbatim` inline spans |
| `spoilerForeground` | `Color` | `.secondary` | `spoiler` inline text |
| `spoilerBackground` | `Color` | `.secondary.opacity(0.25)` | `spoiler` inline background |
| `linkColor` | `Color` | `.accentColor` | Links and anchors |
| `superscriptOffset` | `CGFloat` | `5` | `superscript` baseline offset |
| `subscriptOffset` | `CGFloat` | `-3` | `subscript` baseline offset |
| `quoteColor` | `Color` | `.secondary` | Quote text |
| `quoteBarColor` | `Color` | `.secondary` | Quote's vertical bar |
| `codeBackground` | `AnyShapeStyle` | `.quaternary` | Code blocks and ranged tags |
| `codeFont` | `Font` | `.system(.callout, design: .monospaced)` | Code blocks and ranged tags |
| `indentWidth` | `CGFloat` | `18` | Indentation per nesting level |
| `statusTint` | `(TaskStatus) -> Color` | `.green` / `.red` / `.blue` / `.secondary` | Task status symbol colour |
| `statusSymbol` | `(TaskStatus) -> String` | SF Symbols (`circle`, `checkmark.circle.fill`, …) | Task status symbol |
| `statusLabel` | `(TaskStatus) -> LocalizedStringResource` | `TaskStatus.displayName` | Task status menu label & accessibility |
## Localization
NorgUI provides labels for the long-press menu in tasks. These can be localized
either through the package's own string catalog, but can be overridden in
the theme.
```swift
var theme = NorgTheme.default
theme.statusLabel = { status in
LocalizedStringResource(String.LocalizationValue(status.rawValue), table: "Tasks")
}
```
`statusLabel` defaults to `TaskStatus.displayName`.
## Requirements
- Swift 6 tools
- iOS 18 / macOS 15 / visionOS 2
