# ***Features***
- ## blt/fs
- ### loader.h
- std::string blt::fs::getFile(std::string_view path)
- Gets the entire file as a string.
- std::vector\<std::string> blt::fs::getLinesFromFile(std::string_view path)
- Gets the entire file as a string, then splits on the new line character. Then returns a vector of those lines
- std::vector\<std::string> blt::fs::recursiveInclude(std::string_view path, std::string include_header, std::vector<include_guard> guards);
- Recursively include in order based on the include string (include_header) marked by the include guards
- Defaults to C/C++/GLSL preprocessor style (Was designed for GLSL)
- std::string blt::fs::loadBrainFuckFile(const std::string& path)
- Load a brainfuck file recursively, uses ~ to mark the include path
- ### nbt.h
- probably needs to be remade (TODO)
- ## blt/math
- ### averages.h
- blt::averagizer_o_matic
- Computes a rolling average in a dynamically allocated array.
- Useful for average FPS over a period of time
- ### fixed_point.h
-

## blt::profile_t (v2)
The newest version of my profiler solution now features a CPU cycle counter, CPU thread execution time, and wall time. It has more options for
sorting and general printing while featuring a nicer codebase. It is an improvement over blt::profiling while maintaining (almost) complete backwards
compatability. Due to changes in the ABI the `BLT_PRINT_PROFILE` macro deletes the internal profiles and intervals AND takes arguments which match
compatability. Due to changes in the API the `BLT_PRINT_PROFILE` macro deletes the internal profiles and intervals AND takes arguments which match
the new formatting options for profiling v2. However, `BLT_START_INTERVAL`, `BLT_WRITE_PROFILE`, and `BLT_END_INTERVAL` are still the same.
Documentation for this is coming soon, along with more profiling features. the `BLT_*` macros can be disabled by the standard `BLT_DISABLE_PROFILING`
from the v1 profiler. It is encouraged to use the new blt::* profile functions over the macros however these currently cannot be disabled. (TODO)
