An interpreter for grammar files as defined by TextMate. TextMate grammars use the oniguruma dialect (https://github.com/kkos/oniguruma). Supports loading grammar files only from JSON format. Cross - grammar injections are currently not supported.
TextMateSharp is a port of microsoft/vscode-textmate that brings TextMate grammars to dotnet ecosystem. The implementation is based the Java port eclipse/tm4e.
TextMateSharp uses a wrapper around Oniguruma regex engine. Read below to learn how to build Oniguruma bindings.
TextMateSharp is used by AvaloniaEdit.
Just execute dotnet build under the folder TextMateSharp
