Arend is a theorem prover and a programming language based on [Homotopy Type Theory](https://ncatlab.org/nlab/show/homotopy+type+theory).
+ For more information about the Arend language,
visit [arend-lang.github.io](https://arend-lang.github.io/)
or the [documentation](https://arend-lang.github.io/documentation/).
+ For instructions on building Arend locally, general description of the codebase,
there's [ARCHITECTURE.md](ARCHITECTURE.md).
+ For community forums, checkout [this link](https://arend-lang.github.io/documentation/#forums).
+ For editing Arend code, we suggest [IntelliJ Arend](https://plugins.jetbrains.com/plugin/11162-arend)
([instructions](https://arend-lang.github.io/documentation/getting-started#intellij-arend)).
+ The standard library of Arend is [here](https://github.com/JetBrains/arend-lib).
It serves as a math library.
## Usage
### As a binary
You can find release version of Arend binary (a jar file named "Arend.jar")
in the [release](https://github.com/JetBrains/Arend/releases) page.
The Arend jar can be used to typecheck a library:
```bash
$ java -jar Arend.jar [path-to-library]
```
You can also start a REPL:
```bash
$ java -jar Arend.jar -i
```
If you start the REPL at the root directory of a library, the REPL will load the library.
For more information and usage about command line usage of Arend, please refer to `--help`:
```bash
$ java -jar Arend.jar -h
```
### As a library
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](https://jitpack.io/#JetBrains/Arend/-SNAPSHOT),
simply add this to your `build.gradle`:
```groovy
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 "v1.4.0").
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`:
```kotlin
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")
}
```
