getText

Purpose: Copies a value out of a line of text by using sub strings.

Syntax: getText {line} var {startValue} {endValue}

{line}: The line of text to copy a value from.

var: A variable to store the value in.

{startValue}: A value within the line of text of which the ending point marks the beginning of the copied value.

{endValue}: A value within the line of text of which the beginning point marks the end of the copied value.

Notes: This command is a quick and easy way to snatch a value out of the CURRENTLINE after a TextLineTrigger has triggered. If you know of two blocks of text within the line, you can copy out the area of text between them using this command.

Example:

setVar $line "This is a test line to copy text from"
getText $line $value "line to " " text from"

# displays: "copy"
echo $value
