# **BLT v0.20**
|
|
A C++17 common utilities library to make thing easy!
|
|
|
|
|
|
|
|
---
|
|
|
|
# ***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
|
|
- Provides a 64bit fixed point number with 2^32 bits of precision on each side of the decimal
|
|
- Mostly optimal assembly, avoids sign extension by using 64 bit numbers
|
|
- Requires your compiler to support 128 bit numbers
|
|
- Docs: TODO
|
|
- ### fixed_point_vector.h
|
|
- Not finished due to complications in the vector type, this is a TODO
|
|
- ### log_util.h
|
|
- provides overloads for logging math types
|
|
- ### math.h
|
|
- blt::toRadians
|
|
- to radians function (from deg)
|
|
- blt::f_randi
|
|
- fast random integer from seed
|
|
- blt::fsqrt
|
|
- fast inverse square root algorithm, floats only
|
|
- blt::pow
|
|
- power function
|
|
- blt::round_up
|
|
- rounds up to a variable number of decimal places
|
|
|
|
# Specialties
|
|
## blt::logging.v2
|
|
Found in the header file `include/std/logging.h`, blt::logging is a fast and simple
|
|
single header logging library which can be used independently of BLT. Just include
|
|
the header file anywhere in your project and in ONE cpp file define `#define BLT_LOGGING_IMPLEMENTATION`.
|
|
If you are using BLT as a CMake library (as you should!) this is done for you.
|
|
- ### Compile Time Config
|
|
- Using CMake
|
|
- Several options are provided which disable various logging contexts, as such global logging can be disabled by passing `-DBLT_DISABLE_LOGGING:BOOL=ON`
|
|
- Options follow the pattern of `BLT_DISABLE_LEVEL` where level is one of `TRACE`,`DEBUG`,`INFO`,`WARN`,`ERROR`, or `FATAL`.
|
|
- This allows for individual_t logging levels to be disabled while leaving the others functional. These options can be combined.
|
|
- See CMakeLists.txt for a complete list of options.
|
|
- Standalone
|
|
- The CMake options define global variables in a config file. If you are using logging standalone you will need to remove the config include.
|
|
- Macros can be used in the same pattern of `BLT_DISABLE_LEVEL` to disable the various logging levels
|
|
## blt::arg_parse
|
|
blt::arg_parse found in `blt/parse/argparse.h` is an attempt at a near 1:1 replication of Python's argparse in C++.
|
|
Python's argparse is one of the best command line argument parsing solutions with some of the best documentation I've seen.
|
|
The goal was to create an API which would function exactly as the Python docs described, simplifying how much I needed to remember and document for this library.
|
|
## 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 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)

# **Features / Examples**
|
|
- ## Data Structures
|
|
- Queue / Stack
|
|
- faster than std::queue / std::stack
|
|
- backed by a contiguous array
|
|
- ## Utility
|
|
- Simple Random Wrapper Interface
|
|
- Simple random functions based on the PCG Hash
|
|
- ### String Functions
|
|
- starts_with
|
|
- ends_with
|
|
- contains
|
|
- toLowerCase
|
|

|
|
- Logging
|
|
- See blt::logging section above
|
|
- Time
