ListLines
From Auto Hotkey
ListLines
Enables or disables line logging or displays the script lines most recently executed.
ListLines "On|Off"
Parameters
- On|Off
If blank or omitted, the history of lines most recently executed is shown. The first parameter affects only the behavior of the current thread as follows:
On or 1 (true): Includes subsequently-executed lines in the history. This is the starting default for all scripts.
Off or 0 (false): Omits subsequently-executed lines from the history.
Remarks
ListLines (with no parameter) is equivalent to selecting the "View->Lines most recently executed" menu item in the main window. It can help debug a script.
ListLines "On|Off" can be used to selectively omit some lines from the history, which can help prevent the history from filling up too quickly (such as in a loop with many fast iterations). Additionally, performance is reduced by a few percent while line logging is enabled.
Every newly launched thread (such as a hotkey, custom menu item, or timed subroutine) starts off fresh with the default setting for this function. That default may be changed by using this function in the auto-execute section (top part of the script).
The built-in variable A_ListLines contains 1 if ListLines is enabled and 0 otherwise.
On a related note, the built-in variables A_LineNumber and A_LineFile contain the currently executing line number and the file name to which it belongs.
