Just a quick question to everyone here.
I've been trying to remove filenames (lines) from the string that the 'files' function returns. The basic algorithm I've been using is below, but I think I've found a problem in the 'repeat for each chunkType' control structure in Rev.
Here's a little piece of code I was using to test. I've taken the filename checking out of the loop because that's not the problem. Just put this in a button's script and step through it using the variable watcher...
----- on mouseUp
put ".ds_store" & return & "Help File 1.xml" & return & "Help File 3.xml" into fileList
put 1 into i
breakpoint
repeat for each line currLine in fileList
delete line i of fileList
add 1 to i
end repeatend mouseUp -----
The first iteration, the currLine variable gets ".ds_store", and then it deletes line 1. All is okay.
The second iteration, the currLine variable gets the sting "1.xml"... not "Help File 1.xml" as I assumed.
I tried removing the spaces in the file name thinking that may be stuffing up the chunks, but the second iteration results in currLine being set to the string "xml"
If you comment out the line that deletes the line from fileList, the repeat loop works fine.
I know the algorithm is flawed i.e. when you delete line 1, increment i to 2, then iterate again and delete line 2 it's actually deleting the original line 3. This is my buggy test script :) That bug doesn't matter though if each 'repeat' iteration the chunkType isn't correctly being evaluated. Originally, the deletion of a line occurs when a line matches the extension string at the end of the line (can't use 'contains' so I've been using matchText and regular expressions.)
So, my questions are these:
1) Regardless of weather there's an easier way to remove lines from a string that don't match a pattern, is there something wrong with the way the 'repeat for each' control structure evaluates chunks when you manipulate the string it's repeating 'with'?
2) Is there an easier way to remove filenames from a list that don't have specific file extensions?
Oh, I've tried in Rev 2.0.2 and 2.1 and I'm running on Mac OS X 10.2.6
Thanks for reading this far :)
