Hi again, Hugov

Yet another question about TF.ahk Lib

Is this misinterpreting the way this function works?

Code:

F = ScripletLibTitles.txt
Rows := LV_GetCount()
FoundRows := TF_Find(F, 1, Rows, SearchText, 0, 0)

Accroding to the Tf Tutorial, the Syntax for TF_Find is:
TF_Find(Text, StartLine = 1, EndLine = 0, SearchText = "", ReturnFirst = 1, ReturnText = 0)

In my script, I'm using ReturnFirst = 0 return multiple lines
and ReturnText = 0 return line numbers only

Does this mean?
1. the result of the search returns the total lines containing the SearchText OR
2. each line number containing the SearchText result.

When I run the script, if the SearchText is Blank.
It returns each line number separated by comma's.
for the total LV_GetCount value.

If the SearchText contains a String,
It returns the total lines containing the SearchText.

Is this the way it is supposed to work?

I'm trying to find each line number containing the search result
so I can save those line number values and use another routine to go to
each of the line numbers containing the SearchText like this.

Code:

Loop, parse, FoundRows, `,
{
    RN := %A_LoopField%   ; Rn = row number
    LV_GetText(SearchText, RN, 1)
    LV_Modify(RN, "Focus")  ; Focus on Row with Search Text
    LV_Modify(RN, "Select")  ; Selects Row with Search Text
}

Can I use TF_Find to perform this method? If not,
can I modifiy TF_Find for my situation to get each line number?

Or is there another method for getting the line number values? :roll:

Thanks, for any help you can provide.

Have a Merry Christmas and Great New Year. :lol:

An example works best I guess:

Code:

list=
(
Line 1 this is a test hello
Line 2 this is a test hi
Line 3 this is a test how
Line 4 this is a test are 
Line 5 this is a test hello
Line 6 this is a test doing
)
SearchText=hello

MsgBox % TF_Find(list, 1, 0, SearchText, 1, 0) ; result: 1
MsgBox % TF_Find(list, 1, 0, SearchText, 0, 0) ; result: 1,5
MsgBox % TF_Find(list, 1, 0, SearchText, 1, 1) ; result: "Line 1 this is a test hello"
MsgBox % TF_Find(list, 1, 0, SearchText, 0, 1) ; result: "Line 1 this is a test hello`nLine 5 this is a test hello"
MsgBox % TF_Find(list, 1, 0, SearchText, 0, 2) ; result: "1: Line 1 this is a test hello`n5: Line 5 this is a test hello"

You don't need "Rows" you can simply pass on 0 if you want to find/process all lines in a file or variable.

Hi Hugov,

Thanks for the Clear, Concise answers :!:

When I put the TF_Find Parameters in a Matrix, I't's even Clearer.

Quote:

TF_Find Paramenters
--------------------
ReturnFirst = 0 return multiple lines
ReturnFirst = 1 return first line only

ReturnText = 0 return line numbers only
ReturnText = 1 return entire line (text). This simulates a basic grep feature
ReturnText = 2 return line numbers + entire line (text). This simulates a basic grep feature
------------------------
TF_Find Parameter Matrix
------------------------
0|0 - 0, 0 returns ALL results by LINE number [1,5]
0|1 - 0, 1 returns All Lines of TEXT containing SearchText
1|0 - 1, 0 returns ONLY 1 Line# [Line1] as result
1|1 - 1, 1 returns ONLY 1 Line#'s TEXT
1|2 - 1, 2 returns ALL Line#'s & Text containing SearchText

Have a Merry Christmas & Great New Year :lol:
