ModifiedFilter

[wojteninho]

What I have in my mind is to have an easy way to filter out files by modification date.
Say for instance we want to filter out files modified since yesterday:

yesterday := time.Now().AddDate(0, 0, -1)

s := NewBuilder().
     Files().
     In("/my/photos").
     Modified(After(yesterday))    
     MustBuild()

for item := range MustScan(s.Scan(context.TODO())) {
    ...
}

Another example is:

yesterday := time.Now().AddDate(0, 0, -1)

s := NewBuilder().
     Files().
     In("/my/photos").
     Modified(Before(yesterday))    
     MustBuild()

One more could be the between two dates:

twoDaysAgo := time.Now().AddDate(0, 0, -2)
yesterday := time.Now().AddDate(0, 0, -1)

s := NewBuilder().
     Files().
     In("/my/photos").
     Modified(Between(twoDaysAgo, yesterday))    
     MustBuild()

Behind the scenes it should be the new implementation of Filter interface, and in the builder calling Modified(...) we should add one more filter.

Check how we eventually combine multiple filters here. Filters comes so far from calls to either Files() or Directories() or Match(...).

Happy to discuss further 😄 👍
