Drawing a blank! AHK Gods Unite!

[coder_chick]

I am drawing a blank. I have GUI that asks for a text file (haystack) and asks for some keywords to search each line of the file for. I basically want to read the file using Loop, Read (given it reads one line at a time and some files could be large), and then check each line of the file for each of the provided terms (which could vary each time), and if the line contains a term, have it write (fileappend) the entire line of that haystack file to a new log.

While I am sure I could hard code a bunch of individual checks for each terms, there has to be a way to loop through each of the terms or with some sort of OR so that the script can be dynamic depending on the terms provided each time.

If you could help me with sample code that I could play with, that would be a big help.

Code: Select all

You can have the data entered instead of one per line entered as keyword1,keyword2,keyword3

and then in your loop do

if A_LoopReadLine contains %terms% {
FileReadLine, TheLine, TheFileName, % a_index
FileAppend, % theline, YourfileName.txt
}

The following does work, so that is promising. But is there a way I can take the input from the edit field (one term per line) and create the variable where they are delimited by comma. In other words, still allow the user to enter them in one per line, and once they push the button to execute, the script concatenates the terms with commas in between and then leverages it as shown below?

Code: Select all

terms = big,red,dog,apple

Loop, Read, %File%
{
if A_LoopReadLine contains %terms% 
{
FileAppend,%A_LoopReadLine%`n,log.txt
}
}

Alternatively, you could put the terms in an array/index-based object and use a for-loop.

Code: Select all

; sometime after submitting the GUI info
termsObj:=strSplit(terms,"`n")

; inside file-read loop
for i,a in termsObj{
    if(inStr(a_loopReadLine,a))
        fileAppend,% a_loopReadLine,file.txt
}

Considering that using a matchlist would also be looping through each item in the list anyway (behind the scenes), or using regex, speed/efficiency should be nearly the same.

Edit: if you'd rather use a matchlist, you can simply do terms:=strReplace(terms,"`n",",") to change from line-delimited to comma-delimited.
