or: A Python-esque programming language for C/C++ programmers.

About this project:

Designed and programmed by Daniel Ellingson

Tools/languages used:

• Bison: for grammar
• Flex: for lexing
• C++: for functionality

The PRSE compiler (prsec) is software that is used to compile programs written in the PRSE language into runnable binaries, or into equivalent C++ programs.

The PRSE language is a C-like programming language focused on ease-of-use with syntax similar to C/C++, but with functionality that more closely resembles Python.

Language highlights:

• PRSE is statically- and strongly-typed. Variables that are initialized as a given datatype remain that datatype until they go out of scope.
• PRSE uses Resource Acquisition Is Initialization (RAII). Variables must be initialized with some non-null value.

Design goals:

• Functionality inspired by:
  • Python: for loops, dictionaries, range(), easy conversion between data types
  • C/C++: general look
  • R: vectorization
  • More to explore...
• Use clean, straightforward grammar
• Don't use syntactic whitespace.

Extras to be implemented later:

• CLA option: --sacrifice
  • Sacrifice a file to the PRSE compiler
  • If the code compiles, file is spared
  • If any errors are found, the file is destroyed
  • Hardcore mode: --sacrifice=anyways sacrifices a file regardless of errors, so that you are left with only a binary or nothing at all.

Development:

Dependencies:

• Bison 3.7.1 or newer
• Flex 2.6.4 or newer
• Clang++ 10.0.0 or newer

Note to new users:

• Basic knowledge of Linux is necessary to use this program.

• I recommend checking out a few tutorials for how to use a Linux shell. If you are running Windows 10, Microsoft has been developing the Windows Subsystem for Linux for quite some time now, and this virtual environment is what I have been using to develop PRSE. It gives you access to a complete Linux terminal emulator, which will allow you to build and run the PRSE compiler.
• The PRSE compiler has thus far only been tested on Ubuntu Linux. Windows support may or may not come sometime in the future.
