TennessineC

A small C compiler, written in pure Java, which is able to craft i386 Windows executables.

Currently, supports basic FFI (via #pragma tenc import directives), variables, functions (still WIP though), "while" loops, "if" statements, expressions containing braces, variables, function calls, constants and summation, subtraction operators. The sole data type currently supported is int (32-bit word).

Note that at this moment I don't plan to strictly follow any of currently existing C standards, so this will probably remain a toy compiler.

Obtaining a pre-built binary

Please navigate to Releases section.

Compiling examples/test.c

Use the following command: java -jar TennessineC.jar -s examples/test.c -dp -e WinI386 -o test.exe (-dp stands for Debug Preprocessor)

The compiler should craft the test.exe file.

Building

Step 1. Ensure you have JDK 8 (or above) installed;

Step 2. Clone the repository: git clone https://github.com/minecraft8997/TennessineC;

Step 3. Import the project into IntelliJ IDEA;

Step 4. Navigate to File -> Project Structure -> Artifacts -> Add -> JAR -> From modules with dependencies...

Step 5. Select the main class ru.deewend.tennessinec.TennessineC, press OK;

Step 6. Press Apply;

Step 7. Navigate to Build -> Build Artifacts... -> TennessineC:jar -> Build;

Step 8. Your jarfile will be located in the out/artifacts/TennessineC_jar folder.

What I use for development

I was inspired to start this project after checking out the documentation which fits into a single PNG image – PE101.

Currently, for development I use Tiny C Compiler to compile test snippets and Ghidra for researching the output.
