Syntax

Description

Syntax is an important part of using davinci and this page is desined to give the user a better understanding of how to properly input data into various types of functions. There are two main ways to pass information to a function, explicitly or by an ordered list of unnamed arguments or any combination of either.

Input Types:

• BYTE - values from 0 to 255
• SHORT - values from -32768 to 32768
• INT - values from -2,147,483,648 to +2,147,483,647
• FLOAT - values from -3.402822655e+38 to +3.402822655e+38
• DOUBLE - values from tiny to huge
• VAR - any type of davinci variable (including arrays, strings and various other data types)
• STRUCT - a davinci structure containing the specified elements
• STRING - a arbitrary length item composed of characters
• TEXT - an array of strings
• BOOL - values of either 1 or 0

Definition of Inputs:

In the explicit definition of inputs, the variable name will appear and be followed by the type of data it accepts.

For example: function(data = VAR, name = STRING )

In non-explicit definition of inputs, the argument number ($1, $2,...,$n) will be shown follwed by the type of data it accepts.

For example: function($1 = VAR, $2 = STRING )

After the function definition, the meaning each input will be explained regardless of if the inputs are explicitly or non-explicitly defined.

Optional Inputs:

By allowing some inputs to be optional, davinci has the ability to have preset values that the user doesn't need to enter for the function to work. A good example of this usage is assuming a null value in functions like thm.deplaid.

Optional inputs are enclosed by square brackets ( [ ] ) and defined as ususal.

For example:

function(data = VAR, [ ignore = FLOAT ])

function($1 = VAR, [ $2 = FLOAT ])
