What is this

This is a collection of utilities that I sometimes use in my projects.

Plans

• use less features of modern standards when they are not available (via ifdefs)
• more tools that I personally use often but which are absent in stl
• add a .clang_format and .clang_tidy with a makefile that formats and checks the code here
• pick only appropriate headers to lower compilation time
• experiments
  • std::pmr - make an allocator that is initialized at startup and replace with it the default allocator. It could be useful to limit the memory used by application and also for tracking the memory usage (allocations can be logged).

TODO

• ReadFile, WriteFile
• Scoped file (or stderr/stdout) logger
• Indent/Dedent
• Universal hash for any ordered collection?
• Type info wrapper with __PRETTY_FUNCTION__ hack
• Enum serialization??? Might be possible with macro definition and constexpr functions
• Intrusive splay tree implementation from my bimap??
• The actual bimap??
• Set of functors like square, cube, power, hash. Along with it - a bundle of utilities that help with functional programming:
  • utils::functional::Compose(f1, f2, ...)
  • utils::functional::Bind(PH, 42, PH, "hello")
  • utils::functional::???
• utils::Pipe(auto) + utils::Pipe operator|(utils::Pipe, auto)
• Sparse bitset implementation plus set operations (intersection, union, difference) (???)
• Home dir: https://github.com/ospray/rkcommon/blob/master/rkcommon/os/FileName.cpp#L40
• move definitions to .cc
• There are not enough std::forwards and sometimes I don't even know if I need to use it.
• platform.hh - platform-dependent functionality
• Python script + library for embedding of binary resources: https://stackoverflow.com/questions/11813271/embed-resources-eg-shader-code-images-into-executable-library-with-cmake

utils::math

• Matrices that are stored in blocks
• Tricks from hacker's delight

Short-term plan

• Reflection for up to 10 fields: ToString specialization, structured bindings, hash, order. And...
• ToString specialization for vectors, hashmaps and other stl containers. Probably make it more generic?
• Self-made range-adapters that don't mutate the stored range and can have chained method calls! Reference methods: iota (with custom step), sort, unique, join, sum, minmax, count, groupby, frequencies, are_distinct, nth, sliding_window, and other popular algorithms. Take inspiration from Java Stream API, python itertools, toolz, topk, etc.
• Write down thiw tip in my cheatsheets: https://stackoverflow.com/a/599416/17549962 (:%norm A \ and :%norm I- )
• More reflection for aggregates?
