Usage

Arend is under active development, so you may expect to depend your project on a development version of Arend, either a certain git revision or the SNAPSHOT version. This is possible via JitPack, simply add this to your build.gradle:

repositories {
    maven { url 'https://jitpack.io' }
}
dependencies {
    // The version of Arend -- can be a short revision, "[branch]-SNAPSHOT",
    // "-SNAPSHOT", or a tag (or a release, like "v1.3.0").
    String arendVersion = "master-SNAPSHOT"
    // Open API for writing Arend extensions
    implementation "com.github.JetBrains.Arend:api:$arendVersion"
    // The generated ANTLR parser
    implementation "com.github.JetBrains.Arend:parser:$arendVersion"
    // The generated protobuf classes
    implementation "com.github.JetBrains.Arend:proto:$arendVersion"
    // The main compiler
    implementation "com.github.JetBrains.Arend:base:$arendVersion"
}

In case you prefer Gradle Kotlin DSL, use the following syntax in your build.gradle.kts:

repositories {
    maven("https://jitpack.io")
}
dependencies {
    // The version of Arend
    val arendVersion = "master-SNAPSHOT"
    implementation("com.github.JetBrains.Arend:api:$arendVersion")
    implementation("com.github.JetBrains.Arend:parser:$arendVersion")
    implementation("com.github.JetBrains.Arend:proto:$arendVersion")
    implementation("com.github.JetBrains.Arend:base:$arendVersion")
}
