* add %unhide pragma
* add a test case
* clean up
* more consistent English usage (+fix some typos)
* add a warning for unhiding not-already-hidden names
* move `unhide` (and `hide`) to the bottom of the source file to avoid having to forward-declare `recordWarning`
This is (for once) not a breaking changes, instead backends will need to opt in to this change, using the utilities in Compiler.NoMangle. See the js backend for an example of how to do this.
This is the first step to being able to use idris to create libraries usable by other languages.
* Only normalise a search goal if it's fast
While we do end up normalising it anyway on success, there might be
things blocking it that make the intermediate terms very big, so only do
it speculatively to see if it's quick.
* Get information about names in reflection
Currently this is only whether it's a function, or data or type
constructor. I expect more may be useful/possible.
* Implemented %noinline
* Removed trailing spaces.
* Added missing case in Reify FnOpt
* Added error message when both %inline and %noinline are set.
* Added test.
* Changed from perror to error
* Fix casts in scheme evaluator
We really need test cases for all the primitives before we can use this
evaluator properly. Also test cases that run inside an environment,
which are a bit harder to construct.
* Add the cast fixes to racket support code
* More racket compile time evaluation fixes
We had the chez version of some primtives in the ct-support file. We
need a full set of tests for the primitives here too...
* Normalise types fully at the REPL
It was a bit odd that we only normalised the scope of function types and
not the arguments, and I can't remember the reason for that if there
even was one.
* Better way of using nf_metavars_threshold
If a term is getting big and probably needs normalising, we now have a
sizeLimit flag in quote, so we can use that instead of checking the size
afterwards. This is a handy heuristic for speeding up unification when
there's a term with lots of suspended computation. Fixes#1991
For error reporting purposes it's better to have an (approximate)
virtual location for code that was introduced by the elaborator
than to have an `EmptyFC` that does not help.
* so much experimentation
* tests that show preliminary evidence the new stuff is working.
* small amount of cleanup
* more cleanup of various troubleshooting code.
* new test case added.
* only log unreachable indices if there are any.
* when traversing deeper simply skip over defaults since they have already been reviewed.
* Remove fallback clause that the changes in this PR correctly identified as unreachable.
* tidying up more.
* move some common functions to a new Core.Case.Util module.
* refer to case builder and case tree under new parent module.
* update imports to look for CaseTree in new submodule.
* update api ipkg
* remove unneeded application operators.
* remove or comment out unreachable default clauses caught by the changes in this PR.
* a bit of code documentation and renaming for clarity.
* bump previous version in CI.
* fix API usage of Util module.
* Add issue 1079 test cases.
* forgot to add new test cases file.
* remove commented-out lines by request of RefC author.
* Use a SortedSet instead of nubbing a list.
* update new case tree import.
* Update src/Core/Case/Util.idr

* remove function with nothing to offer above and beyond a differently named copy of the same code.
* replace a large tuple with a record; discover not all of the tuple's fields were needed.
* fix shadowing warning.

This is for compiled evaluation at compile-time, for full normalisation. You can try it by setting the evaluation mode to scheme (that is, :set eval scheme at the REPL). It's certainly an order of magnitude faster than the standard evaluator, based on my playing around with it, although still quite a bit slower than compilation for various reasons, including:
* It has to evaluate under binders, and therefore deal with blocked symbols
* It has to maintain enough information to be able to read back a Term from the evaluated scheme object, which means retaining things like types and other metadata
* We can't do a lot of the optimisations we'd do for runtime evaluation particularly setting things up so we don't need to do arity checking
Also added a new option evaltiming (set with :set evaltiming) to display how long evaluation itself takes, which is handy for checking performance.
I also don't think we should aim to replace the standard evaluator, in general, at least not for a while, because that will involve rewriting a lot of things and working out how to make it work as Call By Name (which is clearly possible, but fiddly).
Still, it's going to be interesting to experiment with it! I think it will be a good idea to use it for elaborator reflection and type providers when we eventually get around to implementing them.
Original commit details:
* Add ability to evaluate open terms via Scheme
Still lots of polish and more formal testing to do here before we can
use it in practice, but you can still use ':scheme <term>' at the REPL
to evaluate an expression by compiling to scheme then reading back the
result.
Also added 'evaltiming' option at the REPL, which, when set, displays
how long normalisaton takes (doesn't count resugaring, just the
normalisation step).
* Add scheme evaluation mode
Different when evaluating everything, vs only evaluating visible things.
We want the latter when type checking, the former at the REPL.
* Bring support.rkt up to date
A couple of missing things required for interfacing with scheme objects
* More Scheme readback machinery
We need these things in the next version so that the next-but-one
version can have a scheme evaluator!
* Add top level interface to scheme based normaliser
Also check it's available - currently chez only - and revert to the
default slow normaliser if it's not.
* Bring Context up to date with changes in main
* Now need Idris 0.5.0 to build
* Add SNF type for scheme values
This will allow us to incrementally evaluate under lambdas, which will
be useful for elaborator reflection and type providers.
* Add Quote for scheme evaluator
So, we can now get a weak head normal form, and evaluate the scope of
a binder when we have an argument to plug in, or just quote back the
whole thing.
* Add new 'scheme' evaluator mode at the REPL
Replacing the temporary 'TmpScheme', this is a better way to try out the
scheme based evaluator
* Fix name generation for new UN format
* Add scheme evaluator support to Racket
* Add another scheme eval test
With metavariables this time
* evaltiming now times execution too
This was handy for finding out the difference between the scheme based
evaluator and compilation. Compilation was something like 20 times
faster in my little test, so that'd be about 4-500 times faster than the
standard evaluator. Ouch!
* Fix whitespace errors
* Error handling when trying to evaluate Scheme
