I find the following behaviour a little bizarre:
At the macirb prompt (0.8)
fileManager = NSFileManager.defaultManager
@theProjectRoot = '/Users/martin/work/macruby/lots_of_files'
=> "/Users/martin/work/macruby/lots_of_files"
>> filenames = fileManager.contentsOfDirectoryAtPath(@theProjectRoot,
>> error:nil).map {|f| theProjectRoot.stringByAppendingPathComponent(f) }
NameError: undefined local variable or method `theProjectRoot' for
main:TopLevel
If I create a local variable with the name theProjectRoot, then the
statement runs correctly. According to the documentation,
NSFileManager.defaultManager.contentsOfDirectoryAtPath requires a
string; the scope of the variable should be irrelevant, shouldn't it?
