intro

This project aims to generate FixMessage content guided by arguments supplied through a terminal interaction.

---

special value arguments

In order to allow random values to be generated and returned, special values can be provided.
It is basically formed by a semicolon, followed by an identifier, a semicolon and an argument might be provided.

argument	meaning	argument/variable
:randstr:5	a random string of size 5	the value 5 at the end means a variable/argument that must be provided
:now:yyyyMMdd-HH:mm:ss	a string with a local date time formatted, for example; 20200511-14:18:17:233, but it might be used for retrieving both/either date, time or date time portion, by providing corresponding yyyyMMdd, HH:mm:ss, yyyyMMdd-HH:mm:ss, or even yyyyMMdd-HH:mm:ss.SSS.	the yyyyMMdd-HH:mm:ss at the end means the pattern to format the local date time for now(), it is an argument variable and might be provided as needed, once it is a valid date time pattern
:randbigdec:2	a positive big decimal scaled by 2 decimal digits	the value 2 at the end means a variable/argument that must be provided
:randint:	a positive integer value	no argument might be provided for this
:randopt:VAL_A,VAL_B	random options, it is retrieved only one of the available list	arguments must be provided, where options must be split by a comma

---

argument -defaults (optional)

In case the argument -defaults is provided, it must point to some valid file which declares the key value pair, it follows the same rule for every implementation -i, for example, let's assume there's a file called my defaults with the following content;

-11=123
-17=321
-54=1

the items within the file content addressed by the -defaults argument, are first loaded so later are loaded the arguments provided on the command line (terminal), that means values from the file content are overwritten by the arguments provided alongside the command line.

---

argument -i (mandatory)

Argument -i is meant for the desired implementation for the generated fix message content.
