叠加装饰

按行装饰。每类都有 setLine*、setBatchLine*、clear*。clearAllDecorations() 会清掉它们以及 span。

Ready 前 setter 空操作。getLinkTargetAt 返回 ""。

Inlay

enum class EditorInlayType { TEXT, ICON, COLOR }
data class InlayHint(val type: EditorInlayType, val column: Int, val text: String = "", val intValue: Int = 0)

fun setLineInlayHints(line: Int, hints: List<InlayHint>)
fun setBatchLineInlayHints(hintsByLine: Map<Int, List<InlayHint>>)
fun clearInlayHints()

ICON / COLOR 用 intValue（iconId 或打包颜色）。点击：onInlayHintClick。

Phantom

data class PhantomText(val column: Int, val text: String)
fun setLinePhantomTexts(line: Int, phantoms: List<PhantomText>)
fun setBatchLinePhantomTexts(phantomsByLine: Map<Int, List<PhantomText>>)
fun clearPhantomTexts()

行号区

data class GutterIcon(val iconId: Int)
fun setLineGutterIcons(line: Int, icons: List<GutterIcon>)
fun setBatchLineGutterIcons(iconsByLine: Map<Int, List<GutterIcon>>)
fun setMaxGutterIcons(count: Int)
fun clearGutterIcons()

用 setEditorIconProvider 解析位图。点击：onGutterIconClick。

CodeLens

data class CodeLensItem(val column: Int, val commandId: Int, val text: String)
fun setLineCodeLens(line: Int, items: List<CodeLensItem>)
fun setBatchLineCodeLens(itemsByLine: Map<Int, List<CodeLensItem>>)
fun clearCodeLens()

点击：onCodeLensClick。颜色：codeLensColor / activeCodeLensColor。

链接

data class LinkSpan(val column: Int, val length: Int, val target: String)
fun setLineLinks(line: Int, links: List<LinkSpan>)
fun setBatchLineLinks(linksByLine: Map<Int, List<LinkSpan>>)
fun clearLinks()
fun getLinkTargetAt(line: Int, column: Int): String

点击：onLinkClick。

诊断

enum class EditorDiagnosticSeverity { ERROR, WARNING, INFO, HINT }
data class Diagnostic(val column: Int, val length: Int, val severity: EditorDiagnosticSeverity)
fun setLineDiagnostics(line: Int, items: List<Diagnostic>)
fun setBatchLineDiagnostics(itemsByLine: Map<Int, List<Diagnostic>>)
fun clearDiagnostics()

默认绘制：主题诊断色的波浪下划线（Hint 为虚线）。

文档高亮

enum class EditorDocumentHighlightKind { TEXT, READ, WRITE }
data class DocumentHighlight(val column: Int, val length: Int, val kind: EditorDocumentHighlightKind)
fun setLineDocumentHighlights(line: Int, items: List<DocumentHighlight>)
fun setBatchLineDocumentHighlights(itemsByLine: Map<Int, List<DocumentHighlight>>)
fun clearDocumentHighlights()
