This python script allows for the sending and receiving of packets over tcp
This program can be run with python3 netTest.py

commands can be joined together using an & like so:
connect & listen

Used to list either commands or receives.
example: list commands

Used to connect to what ever host & port is set to example: connect

Used to disconnect from the current connection

This command starts listening to the data being received. Requires an active connection.
example: listen

Sends whatever command is given as an argument. Requires an active connection.
example: send test_command

Used to get the properties and the format of the commands and receives
example: get host
example: get receive 4

Used to set the properties and the format of the commands and receives
example: set port 25565
example: set command test 10

setting receives is more complicated it involves three arguments

• -l the length of the the receive
• -n the name of the receive
• -f the format of the incoming receive
  

Together they can look like this:
set receive -l 4 -n test_command -f [uint16]

Formats are constructed using the following syntax:
[type#number]
type can be one of the following:

• uint8
• uint16
• uint32
• float
• double
• long
• char
• byte

The #number represents the number of consecutive numbers that will be received of that type. When omitted, it is implied only a single value exists. Multiple of these types can be strung together. An example of this: [uint8#2][double][uint32#4]. This statement implies that 2 uint8s, then a double, then 4 uint32s will be received.

This is a list of the properties that can be set, what they affect, and what type(int, float, etc) can they be set to.

• host
  • The host to be connected to
  • Can be set to a string
• port
  • The port to be connected to
  • Can be set to an int
• print
  • Should the data received when listening be printed?
  • Can be set to a boolean
• outfile
  • The file that will be printed to and overwritten
  • Can be set to a string
• commandidbytes
  • The number of bytes that make up the id for the sent command
  • Can be set to an int
• receiveidbytes
  • The number of bytes that make up the id for receives
  • Can be set to an int

The rest of the properties should not be edited:

• sizeofuint8
  • Number of bytes in an uint8
  • Can be set to an int
• sizeofuint16
  • Number of bytes in an uint16
  • Can be set to an int
• sizeofuint32
  • Number of bytes in an uint32
  • Can be set to an int
• sizeoffloat
  • Number of bytes in a float
  • Can be set to an int
• sizeofdouble
  • Number of bytes in a double
  • Can be set to an int
• sizeoflong
  • Number of bytes in a long
  • Can be set to an int
• sizeofchar
  • Number of bytes for a char, a series of chars make up a string
  • Can be set to an int
• sizeofbyte
  • Number of bytes in a byte
  • Can be set to an int
