There are various methods to go about it, one would be to use TF_Find to find the lines and pass these on to TF_RemoveLines like so:
Code:
text=
(join`r`n
this is test
with a number of lines
to show how you
can delete "names" from a
file or variable
)

MsgBox % TF_RemoveLines(Text, TF_Find(text, "", "", "with a number of lines|file or variable", 0))
Note TF_Find uses RegEx so the | means search sentence a OR sentence b

Another method would be to use TF_Replace but you would be left with empty lines unless you use `r`nto show how you`r`n but these fail with the first and lastlines because they don't start or end with `r`n. You could use TF_ReplaceInLines but you are left with empty lines as well OR you could have a look at TF_Substract where lines in list1 are removed in list2.

so if i had a variable like this :
LinesToDel = line2|another line|random

TF_RemoveLines("!Text.txt", TF_Find("!Text.txt", "", "", LinesToDel, 0))

this would work? i tried it and it removed everything from the text file

then i tried this :

TF_Substract(LinesToDel, "!Text.txt", "0")

and it didnt remove anything

Update v3.3, 16 April 2010

* Fixed: If you used variables with any of the replacement functions or tried to remove empty lines from a VARIABLE in the following format: variable:=TF_..(variable,"search","replace") and the searchtext was NOT present in the variable it returned an empty variable (e.g. deleted the contents of "variable")
It affected TF_ReplaceInLines, TF_Replace, TF_RegExReplaceInLines, TF_RegExReplace, TF_RemoveBlankLines, TF_RangeReplace
The built-in check only worked correctly for FILES and with the introduction of variables in TF 3 this didn't surface during the test Sad

* Fixed: documentation error for TF_Merge (seperator and filename where swapped) and added examples on how to use TF_Merge in a Loop and with FileSelectFile

Bug reports welcome as I just found the bug and fixed it... Embarassed

Hi I am trying to search a file for certain text and have it tell me the line. Then I store that line number in a variable and have the TF_RemoveLines function remove the line number present in the variable...

Here is what I have.


Code:
settingspingline1:=TF_Find("!settings.ini", "", "", "SettingsManager.floatSet", 1, 0)

If settingspingline1 != 0
{
TF_RemoveLines("!settings.ini", "%settingspingline1%,%settingspingline1%")
MsgBox, Values removed!
}


What the script is doing is deleting all the contents of the settings.ini file instead of just the line I stated in the function.


I hope someone can help...

Your code highlighting the errors:

Code:
settingspingline1:=TF_Find("!settings.ini", "", "", "SettingsManager.floatSet", 1, 0) ; no need for the ! with TF_Find as it doesn't change the file it always returns a variable

If settingspingline1 != 0
{
TF_RemoveLines("!settings.ini", "%settingspingline1%,%settingspingline1%")
MsgBox, Values removed!
}


correct:

Code:
settingspingline1:=TF_Find("settings.ini", "", "", "SettingsManager.floatSet", 1, 0) ; ! removed

If settingspingline1 != 0
{
TF_RemoveLines("!settings.ini", settingspingline1,settingspingline1) ; removed " and % just pass on the variable settingspingline1
MsgBox, Values removed!
}


This should work.

Sorry to bother you again Hugo but I have run into another issue...


I am trying to write text to a line in a file...and it writes fine and to the proper place...but it is not writing the value of a variable...


Here is my code...

Code:
TF_InsertLine("!settings.ini","31",31,"SettingsManager.floatSet GSDefaultLatencyCompensation 0.0%ping%0000")
TF_InsertLine("!settings.ini","32",32,"SettingsManager.U32Set GSInterpolationTime %ping%")


and in the file it gives me

SettingsManager.floatSet GSDefaultLatencyCompensation 0.0%ping%0000
SettingsManager.U32Set GSInterpolationTime %ping%



I have also tried ping without the percent signs. Is there any way I can get this to work?

Never mind...I discovered a solution myself. If there is anyone here with a similar dilemma here is the solution.

You have to insert the line with the variable you want in the text. NO percent marks here.

Code:
TF_InsertLine("!settings.ini","31",31,"SettingsManager.floatSet GSDefaultLatencyCompensation 0.ping0000")


Then replace the text of the variable with the actual value of the variable

Code:
TF_ReplaceInLines("!settings.ini","31",31,"ping",ping)



And then you can write any variable in your script into a file.

You also can do it in the correct way, combining literals and variables:
Code:
TF_InsertLine("!settings.ini","31",31,"SettingsManager.floatSet GSDefaultLatencyCompensation 0.0" . ping . "0000")
TF_InsertLine("!settings.ini","32",32,"SettingsManager.U32Set GSInterpolationTime " . ping)

Is there a TF function that can remove duplicate or matching groups of lines? For example, could it find and remove the red below, but not the orange?

Code:
QT: test 1
test 1
here
QT: test 2
test 2
here and
here
QT: test 3
test 3
here
QT: test 1
test 1
here
QT: test 4
test 4

(edited for clarity)

Not exactly, with with a bit of pre- and postprocessing you could:

Code:
var=
(join`r`n
QT: test 1
test 1
here
QT: test 2
test 2
here and
here
QT: test 3
test 3
here
QT: test 1
test 1
here
QT: test 4
test 4
)

stringreplace, var, var, `r`n, |||, all ; remove all lines breaks
stringreplace, var, var, QT:, `r`nQT:, all ; now put them back in on the QT: lines, that way we have one line per QT section which we can check for duplicates :wink:
var:=TF_RemoveDuplicateLines(var) ; remove duplicates
stringreplace, var, var, `n, , all ; get red of the new lines
stringreplace, var, var, |||, `n, all ; put them back in
MsgBox % Var
Either this or probably a convoluted regex(replace) with some backreferencing magic Shocked
