What about file names which start with ".", but don't have an extension
(e.g. ".svn", ".DS_Store", etc )?
What would be a good pattern to avoid those?
Right now, I break the file path into its components and check the last
one with something like this:
print( ( ".csv" ):match( "^.+%.(%w+)$" ) )
> nil
print( ( ".csv.txt" ):match( "^.+%.(%w+)$" ) )
> txt
Better alternatives?
Cheers
