Passing arrays to other scripts
Hanukka posted a topic in AutoIt General Help and SupportHello peeps, can any one please give an example of passing an array[1D] to another script, then read and display it. Thanks
This script is fairly straightforward. If you ever worked with large files before then this may be of help. By large I mean files of 2 MB or so. Granted this doesn't sound so big but going through the file and parsing it to a 2D array all at once took an astronomical amount of time so I wrote my own function to handle this. I discovered that chunking a large array can boost the performance of iterating through the elements and theoretically this should maintain the performance no matter how large the array size is. I know there is room for improvement so please feel free to contribute! Note: I wasn't able to fully test this on larger files such as 200 MB in size due to AutoIt complaining about an error allocating memory while executing _FileReadToArray(). Any help is appreciated. Features: Chunking (Performance will never degrade over time; I.E. Capable of parsing 200 lines or 20,000 and no performance hit will occur) Automatically re-sizes to dynamic columns Preserves Columns while parsing FAST!!!!!! (I can parse a file that contains 24,000 lines with variable columns up to 8 columns and it will finish under a second.) Script: _ArrayTo2DArray.au3 Example usage: Local $aExport ;Initialize array _FileReadToArray("LARGE TEXT.txt", $aExport) ;Returns 1D array of file Local $aSheet = _ArrayTo2DArray($aExport) ;Converts it to 2D Example Text File: LARGE TEXT.txt This script was inspired by >this post. *Updated attachment: Minor bug fixes* *UPDATE June 6, 2013: I apologize! I just realized I made a complete mess of the algorithm. I'm working on a fix now.* *UPDATE June 6, 2013: Bug fixed! It's attached in the post now.
