Compiler front-end of CMinus, which is the subset of C language
See my porject’s requirements for more details.
You need the meet the following prerequisites before the building:
- JDK: Java is selected as the target programming language.
- Maven: this project use the maven as the build tool.
- Antlr: I choose anltr to help us analysis cminus’s syntax.
Firstly, you need to download the project.
git clone [email protected]:Sh-Zh-7/CMinus.git
Enter the project’s directory and generate the extra source files with antlr. Since these files can be auto generated, I didn’t put them in my repo.
antlr4 -o src/main/java/io/github/cminus -package io.github.cminus -Dlanguage=Java -listener -encoding utf-8 -visitor -lib src/main/resources src/main/resources/CMinus.g4
Finally you can use maven to get our package and then execute it. Alias to executing jar is strongly recommended.
mvn package -Dmaven.test.skip=true
alias cminus='java -jar target/cminus-1.0-SNAPSHOT-jar-with-dependencies.jar'
Now you can use cminus to interpret the cminus file (with .cm suffix)！
Try to execute the following command and watch its output!
cminus src/test/resources/examples/example2.cm
I carefully prepare the Github issue-bot for you to test my compiler.
Check this page to see how you can let the issue bot understand your CMinus code.
Note there is also a issue template to guide you how to write the correct issue to test.
