Go port of DotNet LINQ using generics introduced in Go 1.18
Currently implemented
- Where
- Select
- Range
- Foreach
- Min(By)
- Max(By)
- Average
- Sum
- First
- Last
- Skip(While)
- Take(While)
- Contains
- Any
- Join
(OrderBy And GroupBy will always access all items. For performance and ease of use reason I'll not implement them in IEnumerable way. Please use glinq/garray package instead)
Adapters:
-
FromSlice
-
FromMap
-
ReadLines (wrapping bufio.NewScanner)
-
sqlxq.Queryx (wrapping sqlx.Queryx)
-
ToSlice
-
ToMap
Also some similar utilities directly for slices in the glinq/garray package. These are more handful, without FromSlice/ToSlice conversion.
- Sort(Descending)
- SortBy(Descending)
- Map
- ToMap
- Filter
- Apply
- RemoveIf
- Contains
- (Last)IndexOf
- (Last)IndexWhere
- First, Last
- Concat
- ShallowCopy
- Sum
- Average
- GroupBy
- Count
- Reverse
Also a generic SyncMap type (should I separate it in another repository?)
- Load
- Store
- Range(E)
- Delete(If)
- LoadAndDelete
- LoadOrStore
- LoadOrNew
- LoadAndUpdate
- ToSlice
- Keys
- Len
- Clear
- PopAll
And more to come...

l2 := []string{`the`, `lazy`, `dog`, `jumps`, `over`, `the`, `silver`, `fox`}
garray.SortByDescending(l2, func(x string) byte { return x[len(x)-1] }) // sort descending by the last character
fmt.Printf("%v\n", l2) // [lazy fox jumps silver over dog the the]
