TM4E brings Java API to tokenize textual documents according to TextMate grammars with an Eclipse IDE client that can do syntax highlighting according to this tokenization; and Eclipse IDE client for VSCode Language Configuration to support matching bracket, auto close, on enter support.

TM4E is an official Eclipse.org project so it conforms to typical Eclipse.org requirements and guarantees.

You can install TM4E from the update site https://download.eclipse.org/tm4e/releases/latest/. TM4E is usually installed together with its consumers, so end-user should usually not need to directly install it.

The latest snapshot build can be installed from the update site https://download.eclipse.org/tm4e/snapshots/.

Snapshot binaries of org.eclipse.tm4e.core are available at https://repo.eclipse.org/content/repositories/tm4e-snapshots/org/eclipse/org.eclipse.tm4e.core/. You need to add the following repository configuration to your Maven settings.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<settings>
  <profiles>
    <profile>
      <repositories>
        <repository>
          <id>tm4e-snapshots</id>
          <name>tm4e-snapshots</name>
          <url>https://repo.eclipse.org/content/repositories/tm4e-snapshots/</url>
          <releases><enabled>false</enabled></releases>
          <snapshots><enabled>true</enabled></snapshots>
        </repository>
      </repositories>
    </profile>
  </profiles>
  <activeProfiles>
    <activeProfile>tm4e-snapshots</activeProfile>
  </activeProfiles>
</settings>

Then you can reference the dependency in your pom.xml like so:

<dependencies>
  <dependency>
    <groupId>org.eclipse</groupId>
    <artifactId>org.eclipse.tm4e.core</artifactId>
    <version>[VERSION]-SNAPSHOT</version>
  </dependency>
</dependencies>

The following class and modules should be used as entry point provides:

• org.eclipse.tm4e.core provides the Java TextMate tokenizer. This project is a Java port of vscode-textmate written in TypeScript. This Java API can be used with any Java UI Toolkit (Swing, Eclipse, etc). See Core section for more information.
• org.eclipse.tm4e.ui provides the Eclipse org.eclipse.jface.text.presentation.IPresentationReconciler TMPresentationReconciler which is able to tokenize an editor content by using a given JSON, PList TextMate grammar and do syntax coloration. See UI section for more information.
• org.eclipse.tm4e.languageconfiguration provides the VSCode Language Configuration to support matching bracket, auto close, on enter support with a simple language-configuration.json.

An example with TypeScript:

Here are some projects that use tm4e:
