Hi all.
I remember reading in a post that someone had made a stack that would walk
through a file folder and enumerate all the files and folders. I cannot for the
life of me find it in the Livecode Share site or the forums. I cannot search
for “list files” or “find all files” because the forum search complains the
words I am searching for are too simple! <GAAAHHH!>
I have written a command to do it and it works up through the files in the
first folder it finds, but when it comes to going back to a prior recursion it
does not seem to work. Here is the handler:
on enumerateFilesAndFolders theCurrentPath, @theCurrentList
set the defaultFolder to theCurrentPath
put the files into theCurrentFileList
put the folders into theCurrentFolderList
put theCurrentFileList & theCurrentFolderList into theCurrentFilesAndFolders
filter theCurrentFilesAndFolders without ".*"
sort theCurrentFilesAndFolders Ascending
repeat for each line theCurrentLine in theCurrentFilesAndFolders
put theCurrentPath & "/" & theCurrentLine into thePath
if there is a file thePath then
put thePath & cr after theCurrentList
else if there is a folder thePath then
put thePath & “/“ & cr after theCurrentList
put thePath into theCurrentPath
enumerateFilesAndFolders theCurrentPath, theCurrentList
end if
end repeat
end enumerateFilesAndFolders
It seems after the recent iteration is finished, the value of theCurrentPath is
not reverting to the version of the prior iteration instance. In other words,
it seems to be global to all instances of the iterations of the handler. I was
under the distinct impression that each iteration had it’s own copies of a
given variable because of the implicit scoping used by Livecode. Apparently I
am mistaken.
I would like to see how anyone else has done a file walker.
