loop read file - tab characters at beginning of line are stripped Topic is solved

[subodhjoshi]

[searched here for 'loop read file tab beginning' which did not bring up any results]

When using loop, read to read a file, the tab characters at the beginning of each line are stripped. I dont see any options to preserve them. Do not want to use FileRead and then parse the string - I do not even know if it will have this same issue. Any ideas?

Here is piece of code that I am using;

Code: Select all

Loop, read, %FromFolder%%InputFile%
{    ;; ------------------------ LOOP 58748 BEGINS

	currline = 
	currline = %A_LoopReadLine%

	;msgbox %currline%
	
	;; work on the line. If certain text strings are found in a line, modify them as needed
	;; write any lines (changed or unchanged) to a variable, separated by newline char
	
	;; write the variable to a new file

}

Thanks in advance for your time.

AutoTrim Off

"On: In a statement such as Var1 = %Var2%, tabs and spaces at the beginning and end of a Var2 are omitted from Var1. This is the default.
"Off: Such tabs and spaces are not omitted."

I am not finding that to be the case. I just did a very simple test script, and the MsgBox showed the leading tabs from the text file.

Code:

Code: Select all

Loop, Read, test.txt
	MsgBox, % ">>>" A_LoopReadLine "<<<"

test.txt:

Code: Select all

	one leading tab
		two leading tabs
			three leading tabs

@boiler: Indeed, "A_LoopReadLine" does preserve leading tabs in a line but when "currline" is assigned value of "A_LoopReadLine" , they are stripped.

@KeypressGuy: "AutoTrim off" worked like a charm - THX!

Admin - please close the thread. Unless of course there are other working solutions that would possibly be posted here.

As an alternative to AutoTrim off you can use 'expression syntax'. Replace
currline = %A_LoopReadLine% with
currline := A_LoopReadLine

@TAC109: Indeed. Thx. And using := to assign variables does not trim EVEN WHEN Autotrim is set to 'on'.
