Including appropriate casts, and Num/Eq/Ord/Show implementations.
Also includes new primitives in Data.Buffer, and calls to foreign
functions in C as 'unsigned'.
If available (sometimes, say a top level expression, it might need
inferring so there'll be no goal available). Also add the ability to log
the current goal, or indeed any term.
Add %runElab and start on scripts, although all they can do so far is
check a term. This does gives us, sort of, "template Idris" (as
demonstrated in test reflection002)
Can't export a type which refers to a private name. This has caught a
couple of visibility errors in the libraries, code and tests, so they've
been updated too.
Don't get too excited yet - I want this in so that it doesn't get too
out of sync, but I still have to think about exactly how it's going to
work in practice.
This means it abstracts over the value syntactically, rather than by
value, and can significantly speed up elaboration where large types are
involved, at a cost of being less general. Try it if "with" is slow.
There are more flags we want on with (well, at least one: "proof")
This was taking too long, and adding too many things, because it was
going too deep in the name of having everything accessible at the REPL
and for the compiler. So, it's done a bit differently now, only chasing
everything on a "full" load (i.e., final load at the REPL)
This has some effects:
+ As systems get bigger, load time gets better (on my machine, checking
Idris.Main now takes 52s from scratch, down from 76s)
+ You might find import errors that you didn't previously get, because
things were being imported that shouldn't have been. The new way is
correct!
An unfortunate effect is that sometimes you end up getting "undefined
name" errors even if you didn't explicitly use the name, because
sometimes a module uses a name from another module in a type, which then
gets exported, and eventually needs to be reduced. This mostly happens
because there is a compile time check that should be done which I
haven't implemented yet. That is, public export definitions should only
be allowed to use names that are also public export. I'll get to this
soon.
As it was in Idris1 being able to override some, or introduce new, options to an Idris IPKG is beneficial. For example, generate code for multiple codegens from a single source.
Overridable options are:
+ `--quiet`
+ `--verbose`
+ `--timing`
+ `--dumpcases <file>`
+ `--dumplifted <file>`
+ `--dumpvmcode <file>`
+ `--debug-elab-check`
This is mostly to make it easier to write linear function types without
having to invent names for everything, which might be noisy. Also it
improves the display of linear function types when the name isn't used
in the scope.
I don't know how complete this is, but it certainly detects some of the
most obvious cases which are most likely to be bugs.
While I'm at it, this is as good a time as any to add a general way of
reporting warnings, similar to the way of reporting errors.
Still a couple of things to resolve in coverage and totality checking
before we can switch on %default, so don't expect quite the right
behaviour just yet. More progress though!
Also working on this has caught a few totality errors in the Idris 2
code base that Idris 1 missed... so these are fixed on the way.
The hack (optimisation?) to normalise integer literals when below some
threshold is fine on the RHS, but on the LHS causes problems since we
need them in normal form for pattern matching. Fixes#112
This improves coverage checking, because it can now see that things like
(Z = S x) and (x = S x) are empty. Previously, it only checked that all
possible constructors had a disjoint index. Now, it looks for matches
and checks for disjointness in the matches, which catches a lot more
things especially with equality.
This is added to functions which are guaranteed to be productive. The
check is currently very conservative - just added when every clause is
constructor headed (or headed by an AllGuarded function), and there are
no other function applications.
If we never evaluate under Delay at all, we won't inline interface
methods, which means productive things defined in an interface can never
be today. So, make sure to set the tcinline flag before quoting the
Delayed closure.
We also need to separate building the runtests binary from running the
tests, because runtests refers to the boostrap libraries, and the tests
refer to the newly built libraries.
This worked locally, using inconsistent TTC versions for the bootstrap
version and new version, but let's see what it does on a clean machine
As in Idris 1 - if an interface declares a method as total or covering,
then all implementations have to satisfy that.
Temporarily turn off %default directive again, at least until totality
checking works as it should (this is probably better than removing it
from various places because I'll forget to put them back)
This means temporarily removing some '%default total' from the libraries
and tests, since the input for codata checking isn't right yet (it needs
appropriate use of inlining)
Should have done this ages ago, it was much easier than I expected...
this adds an explicit error clause before running the pattern match
compiler for runtime case trees, but only if the coverage checker finds
there are missing cases.
* Ignore build artifacts in 'tests' directory
* Remove unused variables in makefiles
* Add 'bootstrap-clean' rule to delete build artifacts from 'bootstrap' directory
* Add 'distclean' rule to delete all build artifacts from the source tree
