About

The header-only part of the Lol Engine framework.

Containers

header	description	examples
`<lol/narray>`	n-dimensional dynamic array containers	● `lol::narray<int, 4>` ● `lol::array2d<float>`, `lol::array3d<uint8_t>` ● `lol::narray_span<int, 4>` ● `lol::span2d<uint8_t>`, `lol::span3d<float>`

Math

header	description	examples
`<lol/bigint>`	big integer calculations
`<lol/half>`	half-precision (16-bit) floating point numbers	`lol::half x = 2, y = 3;` `x /= y;` `float z = x;`
`<lol/math>`	math constants, functions, random number generators, polynomials
`<lol/noise>`	Perlin and simplex noise
`<lol/real>`	arbitrary precision floating point numbers
`<lol/transform>`	quaternion, matrix and SQT transformation utilities
`<lol/vector>`	GLSL-compatible vector classes	● `lol::vec2`, `lol::vec3`, `lol::vec4` ● `lol::ivec2`, `lol::ivec3`, `lol::ivec4` ● also: `lol::u8vec3`, `lol::f16vec4`, `lol::vec7`, `lol::ivec11`… ● swizzling: `v1 = v2.xyy;`, `v2 += v3.bgr;a` ● functions: `dot()`, `length()`, `min()`, `clamp()`…

Sytem

header	description	examples
`<lol/dialogs>`	portable file dialogs (imported from samhocevar/portable-file-dialogs)
`<lol/file>`	file reading utilities	● `lol::read(filename, data)` for any `std::string` or `std::vector` ● `lol::write(filename, data)`
`<lol/format>`	ensure `std::format` is available, using a fallback if necessary
`<lol/msg>`	simple message logging	● `lol::msg::info("hello\n");` ● `lol::msg::debug("%d %d\n", x, y);` ● also `lol::msg::error`, `lol::msg::warn`
`<lol/thread>`	threading and timing	● `lol::thread` ● `lol::queue<int, 200>` (thread-safe FIFO queue) ● `lol::timer` (high precision timer)
`<lol/utils>`	various utilities: environment variables, std::map and std::vector extensions…
