Minimal syntax analyzer for FanC programming language

Slim - FanC Syntax Analyzer

Usage

# Library Dir
cd Lib

# Build parser
make all

# Input FanC program
parser < input.in > output.out

Testing

Use Test/in folder for input files and Test/res for expecting results.

# Run Tests
./Tests/runTests.sh

Example

Input FanC program to be analyzed:

// Skip comment
void printOk(bool isOk) {
    if (isOk) print("ok");
}

void main()
{
    int x = 4;
    byte y = 100 b;
    printOk(x>y);
    int z;
}
