BT standard library

The packages every BT program can use, in games and tools alike: printing, text, math, files, time, networking and more. Include a package by its name, for example include "io";, to use its functions and types.

The engine's own packages are in the cTurtle API reference.

Functions and methods can fail unless marked ^infallible; handle a failure with ? or !! (see Errors).

Package	Contents
buffer	Growable byte storage for building, parsing, reading and writing binary data.
files	Read and write files, and list, create and remove directories.
io	Print text to the console, and read or write the program's standard input, output and error streams.
json	Read JSON documents and look up their values by path (JSON Pointer, such as "/player/name").
math	Math on floats: square roots, powers, logarithms, trigonometry, rounding, minimum and maximum, and checks for infinity and NaN.
process	Run other programs, read the program's command-line arguments and environment variables, and resolve and inspect paths.
regex	Regular expressions: compile a pattern once, then find matches and their captured groups in text.
socket	TCP network connections: connect to a server or listen for clients, then send and receive bytes.
string	Text: the methods every string has (length, slicing, searching), and conversion between strings, numbers and buffers.
sync	A lock for tasks that share data, so only one task changes it at a time.
time	Clocks and timers: wait for a while, measure how much time has passed, and read the current UTC date and time.
