kandi X-RAY | MiniScheme Summary
MiniScheme is a tiny scheme interpreter written in Python 2.7. The interpreter is a single file (scheme.py) and is less than 40 lines of code. In the ./tests folder there is a series of tests that check the interpreter for correctness. You may find this useful if you wish to modify the interpreter's source code. Inspired by . I will be writing a short tutorial series (likely 3 installments) that will explore the creation of a small scheme interpreter with error-checking, macro support, and a library of built-in functions. Watch for updates if you're interested.

QUESTION
I'm not quite sure why this is happening, as it didn't happen on my other project with a nearly identical setup. I'm working on a Java project with Maven and want to run my test suite upon pushing the code to GitHub. I can do a mvn compile test -Dtest=InterpreterTester
and it will work fine locally. If, however, I push the code to GitHub, the build test fails with a bunch of cannot find symbol
errors and package x does not exist.
Again, this doesn't happen locally and I've used a similar setup in a previous project (in fact, the .yml file was copied verbatim and the .pom file only differs in the version of ANTLR). Can anyone see what might be going wrong?

ANSWER
Answered 2022-Jan-01 at 02:12Fixed it on my own - turns out that, with ANTLR and Maven, the .g4
file must be inside a package of the same "name" as the rest of the project. For instance, my .g4
file was inside src/main/antlr4/mygrammar.g4
, when it should have been in src/main/antlr4/com/myproject/mygrammar.g4
because the rest of the project's structure is src/main/java/com/myproject/...
.
This, in turn, allows Maven to recognize the grammar location and generate the correct files with mvn clean compile
.

Install MiniScheme
You can use MiniScheme like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
