Joachim Breitner	d60ef53d54	refactor: make CCPO class Prop-valued (#11425 ) This PR changes `Lean.Order.CCPO` and `.CompleteLattice` to carry a Prop. This avoids the `CCPO IO` instance from being `noncomputable`.	2025-12-04 13:33:36 +00:00
Markus Himmel	fa67f300f6	chore: rename `String.ValidPos` to `String.Pos` (#11240 ) This PR renames `String.ValidPos` to `String.Pos`, `String.endValidPos` to `String.endPos` and `String.startValidPos` to `String.startPos`. Accordingly, the deprecations of `String.Pos` to `String.Pos.Raw` and `String.endPos` to `String.rawEndPos` are removed early, after an abbreviated deprecation cycle of two releases.	2025-11-24 16:40:21 +00:00
Rob23oba	80df86dfdd	feat: add more `MonoBind` instances for monad transformers (#10230 ) This PR adds `MonoBind` for more monad transformers. This allows using `partial_fixpoint` for more complicated monads based on `Option` and `EIO`. Example: ```lean-4 abbrev M := ReaderT String (StateT String.Pos Option) def parseAll (x : M α) : M (List α) := do if (← read).atEnd (← get) then return [] let val ← x let list ← parseAll x return val :: list partial_fixpoint ```	2025-09-03 17:15:41 +00:00

chore: rename String.ValidPos to String.Pos (#11240 )

This PR renames `String.ValidPos` to `String.Pos`, `String.endValidPos`
to `String.endPos` and `String.startValidPos` to `String.startPos`.

Accordingly, the deprecations of `String.Pos` to `String.Pos.Raw` and
`String.endPos` to `String.rawEndPos` are removed early, after an
abbreviated deprecation cycle of two releases.

feat: add more MonoBind instances for monad transformers (#10230 )

This PR adds `MonoBind` for more monad transformers. This allows using
`partial_fixpoint` for more complicated monads based on `Option` and
`EIO`. Example:
```lean-4
abbrev M := ReaderT String (StateT String.Pos Option)

def parseAll (x : M α) : M (List α) := do
  if (← read).atEnd (← get) then
    return []
  let val ← x
  let list ← parseAll x
  return val :: list
partial_fixpoint
```
