This repository contains an implementation of the Lox programming language interpreter taken directly from the book Crafting Interpreters by Robert Nystrom. It uses Apache Maven, Apache's build automation tool commonly used with Java. Instructions for using this repository exist in the repository wiki.

Intended as the main educational tool for CMPSC 201: Programming Languages at Allegheny College,
this repository adopts a branched structureeach chapter, and the name and semantic versioning for each
build represents the chapter from which the code was taken. Branches contain all code from preceding
chapters except where the current chapter modifies it to introduce new features or remedy issues
created in previous exercises.
Given that this repository accompanies the pedagogical Lox language and textbook introducing that language, each branch contains educational content to help learners demonstrate their understanding and intuition about concepts and structures. This content comes in two flavors.
Each branch's README uses the Challenges section concluding each chapter of Crafting Interpreters
as a summative exploration of students' grasp of concepts introduced and reviewed in the chapter. Typically,
at least once students finish the chapter on parsing, this takes the shape of requiring students to implement
additional language features. These are included in the grader via Maven test cases. In some cases, additional
challenges have been added to create a deeper learning experience for students.
This repository caters to a course held in the
Department of Computer and Information Science (CIS) at Allegheny College.
Department pedagogy includes student reflective writing which explores concepts qualitatively, often asking
students to engage in speculation, exercise their intuition, or write about their understandings or
experiences engaging with a topic. These documents are included in the docs folder in each branch and
are also included in the grader's setup, namely by guaranteeing that questions are finished.
GatorGrade is a command-line automated grading system (AGS) developed by Allegheny College faculty and students. For more information on installing and using the system, visit the link provided.
All build in this repository, however, automatically installs and configures GatorGrade in its GitHub Actions workflows. Educators and their students are invited to install the software on their machines to gain the full range of benefits associated withe just-in-time (JIT) style of feedback it provides via specifications grading practices.
Wizard provides actionable issues to students based on the outcome of
their GatorGrader reports via the GitHub issue tracker. When students push content to their GitHub repo remotes,
the tool uses the results of GatorGrade to post an issue detailing all of the objectives they have completed and
those that they have not yet achieved in the form of issue-based tasks.
Arborist protects branches from accidental or haphazard merges. Used
here to protect the main and feedback (created by GitHub Classroom) branches. Sometimes students merge these
with other branches and create very tangled webs. The Arborist prevents this.
The repository's Maven configuration works from the command line, setup included contemplates the content of the Getting Started guide, which outlines how to set up the Java SDK and runtime in addition to helpful Maven tools for VSCode. In addition, this repository's Wiki outlines some of the common Apache Maven lifecycle commands used in compiling, testing and executing the code for the book, outlined in the Compiling and Testing Java Programs entry.
