Text file stripping by string length

Recommended Posts

Ekyda

I'm looking for the best way to strip a very large file (1+ gig) of all lines with characters less than 6 characters.

I know of filereadline and strlen

I would like to iterate through the entire file (using a buffer) that will rewrite the good characters to a new file in the quickest most effecient way possible.

Doess anyone have an open API or an algorithm free to use? my current code is rather slow and ineffecient..

thanks in advance!

so far it goes like this:

filereadline x if strlen >= 6 then addtobuffer

if buffersize >= buffermaxssize then _writebufferandflushit
endif
(not actual code but it gets the logic across.)

im using filereadline so i dont have to load the entire text file to memory.

does autoit still not support multithreading or anything of the sort?

No, and it probably never will.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

thanks for the quick response. I just did some searching on the forums and it seems that Valik says it's impossible.
