A few people have reported issues that this won't build with Idris 1.3.1, which it won't. There's a note in INSTALL.md, but it's clearly not prominent enough! I will do a new release soon, but it does take time to do it properly!
We can't nest delayed elaborators (this is an efficiency constraint, to
prevent excessive searching for ambiguous names) to run elaborator
immediately if delays aren't allowed in delayElab
This is part of what we used to have in Enum but I think it's better to
separate the two. Added implementations for Nat, and anything in
Integral/Ord/Neg, so that we get range syntax (at least when its
implemeted) for the most useful cases.
This required a small change to auto implicit search (and I'm still not
sure about this). Now search arguments right to left, because solving
later arguments may resolve earlier arguments by unification and this
can happen in particular when chasing parent interfaces (which may have
fewer parameters).
Take the earliest failure message, since they'll typically be more
precise (later search groups being for chasing parent interfaces and
defaults). This is mostly as a heuristic to help show whether one part
of a pair failed in implicit search.
At least on Linux, \r needs to be in singles quotes as an argument to tr
or it removes all the 'r' instead! Hopefully it also works this way on
Windows...
These are 'nested' namespaces which are a bit special in that even
private names are visible from the enclosing namespace. This gets the
behaviour for record visibility from Idris 1.
Need to set up nested names appropriately for the with function so that
the environment gets passed through correctly, and use abstractEnvType
to get the type of the with function rather than simply binding the
environment as is.
Now supports with applications on the RHS when auto implicits are
involved. Auto implicit bound names in patterns now become searches on
the rhs in a with-application (I should write this construct up properly
in a paper some time!)
We don't use level, so remove it. Added a field bindingVars which
records whether implicit names should be bound if unsolved. This needs
to be separate from the elaboration mode because we might encounter new
holes inside dot patterns which are matched elsewhere.
