A basic (zero-dependency) natural comparison function for Go.
Sort strings that contain numbers in a way that is more intuitive, e.g:
Dates:
| Natcompare (Low-High) | 1999-3-3 | 1999-12-25 | 2000-1-2 | 2000-1-10 | 2000-3-23 |
|---|---|---|---|---|---|
| Standard (Low-High) | 1999-12-25 | 1999-3-3 | 2000-1-10 | 2000-1-2 | 2000-3-23 |
Filenames:
| Natcompare (Low-High) | 99.doc | 100.doc | 1000.doc |
|---|---|---|---|
| Standard (Low-High) | 100.doc | 1000.doc | 99.doc |
