About

astminer lets you create an end-to-end pipeline to process code for machine learning models.

Currently, it supports the extraction of:

astminer was first implemented as a part of the pipeline in the code style extraction project and later converted into a reusable tool. It is designed to be easily extensible to new languages.

astminer allows you to convert source code cloned from VCSs to formats suitable for training. To achieve that, astminer incorporates the following processing modules:

Usage

There are two ways to use astminer:

Using astminer CLI

  1. Build the CLI from the sources.

  2. Prepare your inputs and configure pipeline options. For config examples, see the configs directory.

  3. To run the CLI, pass the config to the shell script:

    ./cli.sh <path-to-YAML-config>
    

Alternatively, you can run the tool inside the Docker image.

Using astminer as a dependency

Import

astminer is available in the JetBrains Space package repository. You can add the dependency in your build.gradle file:

repositories {
    maven {
        url "https://packages.jetbrains.team/maven/p/astminer/astminer"
    }
}

dependencies {
    implementation 'io.github.vovak:astminer:<VERSION>'
}

If you use build.gradle.kts:

repositories {
    maven(url = uri("https://packages.jetbrains.team/maven/p/astminer/astminer"))
}

dependencies {
    implementation("io.github.vovak:astminer:<VERSION>")
}

Local development

To use a specific version of the library, navigate to the required branch and build a local version of astminer:

./gradlew publishToMavenLocal

After that add mavenLocal() into the repositories section in your gradle configuration.

Examples

If you want to use astminer as a library in your Java/Kotlin-based data mining tool, check the following usage examples:

Please consider trying Kotlin for your data mining pipelines: from our experience, it is much better suited for data collection and transformation instruments than Java.

Contribution

We believe that astminer can find use beyond our own mining tasks.

Please help make astminer easier to use by sharing your use cases. Pull requests are welcome as well. Support for other languages and documentation are the key areas of improvement.

Citing astminer

A paper dedicated to astminer (more precisely, to its older version PathMiner) was presented at MSR'19. If you use astminer in your academic work, please cite it.
