Quick start

kohomology is a Kotlin library published at the maven repository shwaka/maven. You can use it in any kotlin project.

Requirement​

You need to install Java Development Kit (JDK). Here we give an example of installation, but most JDK distributions and versions should be OK.

How to start?​

There are several ways to use kohomology.

The directory kohomology/template serves as a template project to use kohomology. If you are not familiar with kotlin projects, this is a good starting point. See its README.md for detailed usage.

Start from a new Kotlin project​

Create a gradle project as in Get started with Kotlin/JVM | Kotlin (or use an existing gradle project). Then write the following in your build.gradle.kts (or build.gradle):

// If you are using build.gradle.kts (Kotlin script)
repositories {
    maven(url = "https://shwaka.github.io/maven/")
}

dependencies {
    implementation("com.github.shwaka.kohomology:kohomology:0.12")
}

Try online (easiest)​

You can try kohomology online at Calculator. This is the easiest way since no installation is required, but the online calculator has some disadvantages to the above methods:

  • It contains very restricted features of kohomology.
  • It is much slower.
