The prelude interfaces that have default definitions for all of
their fields are declared total so that users are forced to think
about meeting the minimal requirements for an implementation to be
valid.
* 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.
* 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.
integerToNat is only equal to `believe_me` at runtime, not at compile
time. You'd believe it cannot be a problem given that the implementation
of `Cast` is not exported but the REPL reduces everything.
* 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
The previous definition means it won't reduce until it's applied to
4 arguments which may have detrimental effects: ``f `on` fst`` would
for instance stay blocked, with some implicit arguments of the form
`DPair a b`. This means that `b` appears in a negative position in
the expression which may lead to positivity checking rejecting a
datatype defined using `on`!
I have decided to leave `g` and `f` on the LHS because I expect `on`
to be used either:
1. partially applied to two arguments
2. in a section if only applied to 1 and sections get eta-expanded
by the parser so that's fine.
Since `[a..b]` uses `takeUntil`/`takeBefore` indirectly those too had to
be changed to `public export` clashing with `Data.Stream` definitions.
A small readability refactor was made with the `compare` function from
`EqOrd`.
Why:
* To implement robust cross-project go-to-definition in LSP
i.e you can jump to definition of any global name coming
from library dependencies, as well as from the local project files.
What it does:
* Modify `FC`s to carry `ModuleIdent` for .idr sources,
file name for .ipkg sources or nothing for interactive runs.
* Add `--install-with-src` to install the source code alongside
the ttc binaries. The source is installed into the same directory
as the corresponding ttc file. Installed sources are made read-only.
* As we install the sources pinned to the related ttc files we gain
the versioning of sources for free.
- Fix off-by-one error in String reverse
- Correct order of arguments in strSubstr
- Actually use start index of strSubstr
- Reduce memory usage of strSubstr in case of overrunning string end
- Add fastPack/fastUnpack/fastConcat
- Use unsigned chars for character comparisons
- Fix generated C character encodings
* Banners for test pools
* Summary with the list of failing tests at the end
* Option to write the list of failing tests to a file
* Option to read the list of tests to run from a file
* Using these two latest features to add a new make target to rerun precisely the tests that failed last time
It has always bothered me that 'False' got mapped to tag 1 and 'True'
got mapped to tag 0. This doesn't change much in practice (except that
perhaps a code generator might notice some useful things in intToBool)
but I'm changing it now anyway. Also added a couple of inlinings of
boolean operations.
We've had these for a while, used for interface specialisation, but
they're not yet used anywhere else or properly documented. We should
document them soon, but for now, it's a useful performance boost to
always use the fast versions of pack/unpack/concat at runtime.
Also moves a couple to the prelude, to ensure that the fast versions are
defined in the same place as the 'normal' version so that the
transformation will always fire (that is, no need to import Data.String
for the transformation to work).
When bootstrapping, we're building things without packages being
available, so we can't expect to find them when looking for
dependencies. So, we find them another way, with an environment
variable. This flag is to tell Idris not to worry about missing
dependencies in this situation.
We also need to update the bootstrapping code, to deal with the new
version number format and new flag in the ipkg files for the libraries.
I think it's still safe to build from the previous version though - lets
see if CI agrees!
Packages are now installed in a directory with their version number.
On adding a package directory, we now look in a local 'depends'
directory first (to allow packages to be installed locally to another
project) before the global install directory.
Dependencies can have version bounds (details yet to be implemented) and
we pick the package with the highest version number that matches.
`countFrom` must have been made public accidentally:
* it is defined in the ranges section of the file, not stream section
* it is used only in `Range` implementation
* the same function `iterate` is defined in `Data.Stream`
```
countFrom start next
```
is the same as
```
iterate next start
```
Ideally, liftIO would always be linear, but that has lots of knock-on
effects for other monads which we might want to put in HasIO, now that
subtyping is gone. We'll have to revisit this when we have some kind of
multiplicity polymorphism.
It's disappointing to have to do this, but I think necessary because
various issue reports have shown it to be unsound (at least as far as
inference goes) and, at the very least, confusing. This patch brings us
back to the basic rules of QTT.
On the one hand, this makes the 1 multiplicity less useful, because it
means we can't flag arguments as being used exactly once which would be
useful for optimisation purposes as well as precision in the type. On
the other hand, it removes some complexity (and a hack) from
unification, and has the advantage of being correct! Also, I still
consider the 1 multiplicity an experiment.
We can still do interesting things like protocol state tracking, which
is my primary motivation at least.
Ideally, if the 1 multiplicity is going to be more generall useful,
we'll need some kind of way of doing multiplicity polymorphism in the
future. I don't think subtyping is the way (I've pretty much always come
to regret adding some form of subtyping).
Fixes#73 (and maybe some others).
