+# Houseofcompiler
+
+Mini-Java compiler construction project for the 4th semester of computer science at the Baden-Württemberg Cooperative State University in Stuttgart (Horb).
+
+## Supported Java-Subset Syntax
+
+```java
+Base-Types: int, boolean, char;
+Access-Modifier: public, private, protected
+Operators: + - * / % || && == != < > <= => ! = 
+Statements: if...else, while loop, 
+Other Keywords: new, this, null, 
+mentions: - Methods/Constructors are Overloadable
+          - statically-imported Methods: 
+              - System.out.print 
+              - System.out.println 
+              - System.err.print 
+              - System.err.println
+          - no inheritance 
+          - no imports and packages
+          - no interfaces and abstract classes
+          - no Arrays and Exceptions
+```
+
+## Used Tools
+
+* [ANTLR4 v4.9.2](https://www.antlr.org/)
+  * Used to parse the Code into an Abstract Syntax Tree
+* [ASM v9.3](https://asm.ow2.io/) 
+  * Used to generate Bytecode out of the Typed Syntax Tree

+
+## Components
+
+### Parsing + Abstract Syntax Tree
+
+Implemented by [@LukasEEH](https://github.com/LukasEEH):
+* ANTL-Grammar for the JavaSubset
+* Adapter to generate the Abstract Syntax Tree
+
+
+### Semantic Check + Typed Syntax Tree
+
+Implemented by [@Lucs77777](https://github.com/Lucs77777) and [@Raqhael](https://github.com/Raqhael):
+* Semantic-Visitors to typecheck the entire Syntax Tree
+* Semantic Error Handling
+
+### Bytecode generation
+
+Implemented by [@FabiKl](https://github.com/FabiKl)
+* Translation from Abstract Syntax Tree to Java-Bytecode with ASM
+
+### Testing 
+
+Implemented by [@Raqhael](https://github.com/Raqhael):
+* Tests to check if the Abstract Syntax Tree is generated correctly
+* Tests to check wheter the Semantic-Check types the AST correctly and throws errors
+* Tests to check if the Byte-Code is generated correctly (Tested with Java-Reflections)
+* Integration Tests for the Whole Compiler to check different Use Cases
+
+## Installation
+
+This Project using [maven v4.0.0](https://maven.apache.org/) and can be easily installed when using IntelliJ, Eclipse and other JavaIDE's
+
+## Usage
+
+When you wanna Test the Compiler without building a jar file, you can simply go to `src.main.java.main.Testing.java` and Compiles the given .java-File (found in `src.main.resources.*`). It will run the Compiler, builds the .class-Files into the `./build`-Directory and a Java-Reflection loader will invoke a non-statically main method and prints the output to the stdout.
+
+## Downloads
+
+You can find the latest `.jar` of the Compiler [here](#)
+
+### Usage
+
+```
+java -j houseofcompiler.jar <.java-File to Compile> [OutDir-Path]
+```
