As discussed with edwin, let's get rid of the external TT type.
There is no way to get your hands on a TT value anyway so this
should not change anything.
* Allow functions to be marked for foreign export
This relies on the backend knowing what to do with such things, but the
general idea is to mark them with '%export "backend:exportedname"' then
'getCompileDataWith', given a back end, will search for every function
that needs to be exported, as well as every function starting from the
expression to be compiled. This will allow Idris functions to be called
from other languages, where a backend supports it.
This is hard to set up a test case for, for the moment, since no
backends actually do anything with it. So consider it a bit of a
placeholder for now.
* Add missing clause to Eq FnOpt
Thanks to @buzden
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
* Case tree/coverage checking shortcuts
We were calculating some things we didn't need - we can stop computing
the type of a case operator when we know the head, because that's all we
need for coverage checking. We can also abandon checking a left hand
side for coverage purposes if we encounter an empty type. Both of these
can save quite a bit of time in complex cases.
* Normalisation heuristic for pattern variables
If they get bit, fully normalise (like we do with case types) since it's
likely a big term with lots of applications will normalise a lot.
Instead of having UN & RF (& Hole in the near future & maybe even
more later e.g. operator names) we have a single UN constructor
that takes a UserName instead of a String.
UserName is (for now)
```idris
data UserName : Type where
Basic : String -> UserName -- default name constructor e.g. map
Field : String -> UserName -- field accessor e.g. .fst
Underscore : UserName -- no name e.g. _
```
This is extracted from the draft PR #1852 which is too big to easily
debug. Once this is working, I can go back to it.
