phosg

phosg is a basic C++ wrapper library around some common C routines.

A short summary of its contents:

• Byteswapping and encoding functions (base64, rot13)
• Integer types with explicit endianness and transparent byteswapping
• Directory listing, smart-pointer fopen and stat, file and path manipulation
• Hash functions (fnv1a64, fnv1a32, sha1, sha256, md5)
• Basic image manipulation/drawing
• JSON (de)serialization
• Network helpers (IP address parsing/formatting, socket listen and connect functions)
• Functions for getting random data from the OS
• Process utilities (list processes, name <> PID mapping, subprocess execution)
• Time conversions
• std::string helpers like printf, split/join, time and size formatting, etc.
• 2D, 3D, and 4D vectors and basic vector math
• KD-tree and LRU set data structures

This project also includes a few simple executables:

• jsonformat: Parses the input JSON and either minimizes it (with --compress) or reformats it for human readability (with --format).
• bindiff: Shows the differing bytes between two binary files in a colored hex/ASCII view. This just does a direct comparison of the two files byte for byte; it doesn't run any e.g. edit-distance algorithm (yet).
• parse-data: Parses the data format used by phosg::parse_data_string and outputs the result.
• phosg-png-conv: Converts the input image (in any format that phosg::Image can load) to a PNG image.

Building

Building & installing on macOS, Linux, or Windows (in a Cygwin bash shell):

• Install CMake and zlib (zlib-devel on Cygwin).
• cmake .
• make
• make test
• sudo make install

The Windows build does not have continuous integration, so I may accidentally break it and not know for a while. Please file a GitHub issue if it doesn't work.
