バージョン & 機能マトリクス¶

このページでは IDE の互換性情報と、ReScript IntelliJ Plugin の各バージョンで追加された機能の一覧を提供します。バージョニング方針・リリース手順・各バージョン情報の信頼できる情報源については、開発者向けバージョン参照ドキュメントを参照してください。

IDE 互換性¶

プラグインバージョン	IntelliJ Platform	JDK	ReScript	Language Server
0.1.2 -- 0.1.12	2025.3+	21+	v11+	`@rescript/language-server` 1.0.0+（最新の安定版を推奨）

注釈

ネイティブ機能（シンタックスハイライト、コード折りたたみ、ブレースマッチングなど）は Language Server なしで動作します。LSP ベースの機能（補完、診断、定義ジャンプなど）を使用するには、プロジェクトに @rescript/language-server 1.0.0 以降をインストールする必要があります。0.x 系は本プラグインが使用する LSP 拡張プロトコル（rescript/compilationStatus、textDocument/createInterface、textDocument/openCompiled、Semantic Tokens）に対応しないためサポート対象外です。
