ACF Libraries

ACF Libraries

Because of using lua, a very small language, the need arises to build everything from scratch. This can lead to some confusion, apprehension, or just feeling overwhelmed. Here is documentation on what we have now in the form of libraries and common functions. We hope to build some more and use this information to get the juices flowing in regard to ACF.

Some of these are lua libs or ones written for ACF.

join.lua (not working)

INPUT:
This library required the following inputs/parameters.

• Delimiter
  • Could be one or more chars.
• Array
  • Data which is to be joined into a string.

OUTPUT:
This library deliverers the following output/parameters.

• String
  • Could be something like "Word, Word, Word, Word"

CODING EXAMPLE:

-- Set variable/Call for this library
ourlib = require("join")
-- Create a array of data (Not sure if the next row is correct)
arraytojoin = "Bird", "Fish", "Cow", "Hammer"
-- Process the data (note the delimiter)
liboutput = ourlib(";", arraytojoin)

'liboutput' would contain:

Bird;Fish;Cow;Hammer

split.lua

INPUT:
This library required the following inputs/parameters.

• Delimiter
  • Could be one or more chars.
• String or line from a file: bobo~foo~bar~baz~1
  • Data is to be split into a table

OUTPUT:
This library deliverers the following output/parameters.

• Table
  • { 1 = "bobo", 2 = "foo", 3 = "bar", 4 = "baz", 5 = 1}

CODING EXAMPLE:

-- Set variable/Call for this library
strsplit = require("split")
-- Grab the line from a file or input it into the funtcion

line = "bobo~foo~bar~baz~1"

-- Process the data (note the delimiter)
t = ourlib("~", line)

't' would contain:
{ 1 = "bobo", 2 = "foo", 3 = "bar", 4 = "baz", 5 = 1} for a,b in ipairs(t) do print(a,b) end
1 bobo
2 foo
3 bar
4 baz
5 1

validator.lua

This contains multiple different functions that each will validate input in there own way.

• is_ipv4
  • takes input and checks if it is a valid ip address
    • has 3 "." and 4 valid numbers less than 255
• is_mac
  • takes input and checks if it is a valid mac address
    • Correct hex numbers with ":" and 6 fields
• is_integer
  • is the number >= 0 and a whole number
• is_integer_in_range
  • is the number >= 0 and within the range specified
• is_port
  • is the number a valid ip port number 1<n<65535
