PLATYPUS

Frontend compiler for the PLATYPUS language specification

Building

In macOS/Linux

Requires

gcc (tested in version 6.3.x) or clang (tested under LLVM clang-0800.0.42.1)

• make [gcc | clang]
  • No argument will build both versions (this is an aftermath of having to check behaviour in the binary from multiple compilers)
  • It is safe to modify the default to either gcc or clang if you wish. ** SEE NOTES BELOW **
• NOTE: I haven't tested or created make targets for the final implementation yet. This is somewhat buried deep into the backburner

Windows

Requires

• msvc (tested under Visual Studio 2015 with Update 3, however VS 2012 and 2013 shouldn't behave abnormally either, nor should 2017)
• Disable language extensions (use ANSI C)

Running

Running the Buffer only

• macOS/linux
  • $ ./buffer_<compiler> <file> [f | a | m] > <out_file>
• Windows
  • $ buffer <file> f | a | m] > <out_file>

Usage

• F: fixed capacity mode. Buffe will not auto-resize if not enough space for the file
• A: additive mode: Buffer will resize in a linear increment.
• M: multiplicative mode: Buffer will resize based on a pre-set multiplier based on remaining allowed memory space ($SHRT_MAX bytes)

Notes

This is in no way complete, or ready for production in any shape or form. It works up to the parser, but still contains incorrect grammar parsing and some edge cases that causes crashes.

You can modify the initial capacity and increment factor defined in platy.c (should really make that a command line parameter in a future release)

• Increment factor range for additive mode: 1 - 255. (setting this to 0 implies fixed mode, regardless of the mode given in the command line)
• Initial capacity range (in bytes): 0 - 32767 (SHRT_MAX)
• This is an issue caused by my environment's install locations for the C include libraries:
  • buffer.h contains an #ifdef directive checking if WIN32 exists. Due to an upgrade issue with GCC in macOS (possibly only in my machine), malloc.h is actually named mm_maloc.h. If your system uses malloc.h, you can safely delete the check and use the regular filename instead.
