* deprecate Data.Nat.Order.decideLTE
* Add properties for LTE/GTE that produce the difference.
* remove deprecated function now that it is available in the base library.
* remove two deprecated lines.
* remove module deprecated since v0.4.0
* fix prelude reference to renamed primitive.
* finish removing Data.Num.Implementations
* remove deprecated dirEntry function.
* remove deprecated fastAppend. Update CHANGELOG.
* replace fastAppend in test case
* replace fastAppend uses in compiler.
* remove new properties that weren't actually very new.
* 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.
* [ refactor ] user proper int types for Constant
* [ cleanup ] declare standalone TTC implementations for BitsN/IntN
Rather than doing the casting inline, have the (en/de)coding all
side by side in one place
* [ cleanup ] remove duplicated code

* Update version numbers and bootstrap scheme
* Use wall clock time for search timeouts
That was always the intention in any case, rather than the process time.
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.
* Add function that checks whether a file is a terminal device.
* support isTTY function for NodeJS backend.
* don't accidentally interpret 'false' string as truthy number
* less code duplication.
* [ breaking ] remove parsing of dangling binders
It used to be the case that
```
ID : Type -> Type
ID a = a
test : ID (a : Type) -> a -> a
test = \ a, x => x
```
and
```
head : List $ a -> Maybe a
head [] = Nothing
head (x :: _) = Just x
```
were accepted but these are now rejected because:
* `ID (a : Type) -> a -> a` is parsed as `(ID (a : Type)) -> a -> a`
* `List $ a -> Maybe a` is parsed as `List (a -> Maybe a)`
Similarly if you want to use a lambda / rewrite / let expression as
part of the last argument of an application, the use of `$` or parens
is now mandatory.
This should hopefully allow us to make progress on #1703
* Stub for future 'identity' optimisation
I plan to add this later, but I'm using for now for
NaturalToInteger and IntegerToNatural
* Refactor `%builtin`
fixes#1799
- automatically optimise all Natural shaped things
- NaturalToInteger and IntegerToNatural now use
new `Identity` flag (internal use only for now)
which signals the function is identity at runtime
* Use NaturalToInteger and IntegerToNatural for Nat and Fin
Also define show fin in terms of finToInteger, for speed
* Fix name handling for %builtin
* [ tests ] fixes + #1799
* remove %builtin from libs
Add back after next version
* Use resolved names where convenient
Turns out that `Smaller` and `LT` won't unify because
1. the instance Sized Nat is not publicly exported
2. Smaller, and LT are stuck until fully applied
The given changes make that go away.
I can't make sense of this code, it seems to try to convert the
case function corresponding to `let (a, b) = f n in ...` into a
different case function where `f n` and `(a, b)` have been unified.
But if `f n` is a bona fide stuck computation, there's no chance of
this happening.
Just turning this off solves the #1782 and only breaks one function
in the whole of the idris2 repo (I would have expected our current
termination oracle to be too weak to detect it as valid anyway!)
and one in frex (which, again, should not have been seen as terminating).
Also fixes#1460
These entries returned by `readdir` are legacy of Unix API, we don't
really need them. Most APIs do not return them (for example Java
`Files.newDirectoryStream` or Python `os.listdir`).
* add `nextDirEntry` which returns `Maybe String`, so `Nothing` on
the end of directory unlike `dirEntry` which returns unspecified error
on the end of directory
* `dirEntry` is deprecated now, but not removed because compiler depends on it
* native implementation of `dirEntry` is patched to explicitly reset `errno`
before the `readdir` call: without it end of directory and error were
indistinguishable
* test added
* Add trailing newline on non-empty list in unlines
There are several reasons to do that:
* a line in a text file is something which ends with newline,
and the last line is not special
* `unlines []` should be different from `unlines [""]`
* `unlines (a ++ b) = unlines a ++ unlines b`
* Haskell does it
* Change lines function behaviour
