A pseudocode interpreter designed to be compatible with the Cambridge IGCSE and A level pseudocode syntax
The REPL stands for Read Execute Print Loop and is an interface where pseudocode statements can be entered. The statement is immediately executed after it is entered and the result or potential errors are printed to the console to make it easy for debugging.

Runtime Error in file <stdin>:
Division by 0
Traceback:
Program, line 1, column 9
Lanuch the program directly by double clicking the executable
OR
Run it in the terminal with no arguements
The REPL can be used to run files using RUNFILE <file>.
For example, here is a simple hello world program stored in the file hello.pseudo
OUTPUT "Hello World!"
Run it with RUNFILE hello.pseudo
Example output:
> RUNFILE hello.pseudo
==> Running file 'hello.pseudo'
Hello World!
==> Program exited successfully
>
Tip: The program must be stored in the same folder as the executable or the full path of the program has to be mentioned when using
RUNFILE
Navigate to the executable and run it providing the path of the program file as an arguement similar to RUNFILE
Windows:
PseudoEngine2.exe <filepath>
Linux/Unix:
./PseudoEngine2 <filepath>
Make sure you replace PseudoEngine2 with the actual name of the executable or rename the executable
See examples
Make sure cmake and a c++ compiler is installed, then clone the repository and inside its folder run the following commands:
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --config Release
The executable will be generated inside the build folder
