Useful Utilities for Lua!

This file was made firstly for myself, but then I wanted to share it with people, so here it is!

Utilities avaible:

String

• string.random(count,min,max) "count, min, max" are not required, this function returns a random string
• string.split(str,split) this function splits a string to a table
• string.mix(str) see mix
• string.startswith(str,pattern) verify if a string starts with the pattern
• string.endswith(str,pattern) same as above but for the end of the string
• string.encode table for encoding
• string.decode table for decoding
• string.encode.hex(str) encode a string into hex
• string.decode.hex(str) decode a string into hex
• string.encode.b64(str) encode a string into base64
• string.decode.b64(str) decode a string into base64
• string.totable transforms a string to a table

I/O

• io.readfile(path/to/file.txt) reads a file
• io.store(file,content,true) stores data into a file, the "true" mean we do a new line at the end of the file for future storing

Math

• math.mix see mix
• math.calc Calculator sandboxed (You can't inject code)

OS

• os.find("file","dir") search for a file in a directory
• os.clear() clear the terminal, works with all OS
• os.getOS() returns the current OS
• os.getArch() get if the arch is 64 bits or 32 bits
• os.outputexec
  Get the output of a system command
• os.splitpath(path) Splits the path

Table

• table.merge(t1,t2) merges two tables
• table.to2D(str) returns a 2D table version of the string you sent
• table.tostring(tbl) returns a string of the table you sent
• table.list(tbl) return in a string a list of elements of a table, also returns count
• table.head(tbl) returns first value
• table.tail(tbl) returns the tail of the table
• table.find(tbl) find a value in a table
• table.reverse(tbl) reverses a table. Warning: only works with normal keys (1,2,3..)

Console

• console.log(str) logs something with time and date
• console.slowPrint(str) prints something slowly
• console.slowWrite(str) writes something slowly (using io.write)
• console.error(error type, error message, additional infos) advanced erroring
• console.update(bool,str...) Will update the console, bool: is the text slowly appearing.

Others

• sleep(t) will wait the amount of time given
• operator Operators, can always be useful
• morse A table with char for morse in it
• chars a string with all chars, used for string.encode.b64(str)
• mix mix a string or ints
• dostring a remake of the old loadstring for Lua 5.3 - execute a string as a piece of code
• isType Shorter for type(obj) == "obj"
