Manual:Scripting

Loops and conditional statements

Command Syntax Description

do..while :do { <commands> } while=( <conditions> ); :while (

<conditions> ) do={ <commands> };

execute commands until given

condition is met.

for :for <var> from=<int> to=<int> step=<int> do={ <commands> } execute commands over a given

number of iterations

foreach :foreach <var> in=<array> do={ <commands> }; execute commands for each elements

in list

Command Syntax Description

if :if(<condition>) do={<commands>}

else={<commands>} <expression>

If a given condition is true then execute commands in the do block,

otherwise execute commands in the else block if specified.

Example:

{

:local myBool true;

:if ($myBool = false) do={ :put "value is false" } else={ :put "value is true" }

}

Functions

Scripting language does not allow to create functions directly, however you could use :parse command as a

workaround.

Starting from v6.2 new syntax is added to easier define such functions and even pass parameters. It is also possible

to return function value with :return command.

See examples below:

#define function and run it

:global myFunc do={:put "hello from function"}

$myFunc

output:

hello from function

#pass arguments to the function

:global myFunc do={:put "arg a=$a"; :put "arg '1'=$1"}

$myFunc a="this is arg a value" "this is arg1 value"

output:

arg a=this is arg a value

arg '1'=this is arg1 value

Notice that there are two ways how to pass arguments:

•• pass arg with specific name ("a" in our example)

•• pass value without arg name, in such case arg "1", "2" .. "n" are used.

Return example

1 2 ... 31 32 33 34 35 36 37 38 39 40 41 ... 188 189
