Hi,
I have implemented string natural comparison and sorting in the last Gambas 3
revision.
With that, you can, for example, sort a file name array returned by Dir() that
way:
Photo1.jpg Photo1a.jpg Photo1b.jpg Photo2.jpg ... Photo9.jpg Photo10.jpg
Photo11.jpg
Instead of:
Photo1.jpg Photo10.jpg Photo 11.jpg Photo1a.jpg Photo1b.jpg Photo2.jpg
...
Photo9.jpg
For that, use the gb.Natural constant as sort flag.
Moreover, if you have non-ASCII letters, you can add gb.Language to the flag,
and non-ASCII characters will be correctly sorted too. You will get:
Baba.jpg Bébé1.jpg Bébé8.jpg Bébé20.jpg Bibi.jpg Bobo.jpg
instead of:
Baba.jpg Bibi.jpg Bobo.jpg Bébé1.jpg Bébé20.jpg Bébé8.jpg
How does it work?
The string is splitted between parts having digits only (0-9), and parts
having no digits.
Parts having no digits are sorted as normal strings.
Parts having digits are sorted according to their numerical values, unless it
starts with a zero.
Enjoy it!
