I'm playing with some linear structures and finding these useful a lot,
so good to have a consistent syntax for it. '#' is chosen because it's
short, looks a bit like a cross if you look at it from the right angle
(!) and so as not to clash with '@@' in preorder reasoning syntax.
Without --no-index, git compares the files with their state in HEAD.
But we want to compare them to each other! This explain why we were
getting no output whatsoever.
With --word-diff=color, we can easily spot the small changes anywhere in
a line.
If a function is public export, the local definitions also need to be
public export for it to reduce properly. But if they're not, we don't
want them exported or they might affect the module hash and cause
unnecessary rebuilds.
When runing in interactive mode, the diff between expected and output is not being show,
Supposedly, Git-diff returns 0 on successful run and a non-zero for error.
However, this is not being picked up by the test suite.
We change git-diff's error reporting to be more diff like in which:
+ +ve indicates that there is a diff.
+ 0 indicates the files are the same.
+ -ve program error.
This should make diff reporting more robust.
This takes the responsibilty of finding the ipkg away from IDE mode,
which seems sensible given that we can do it ourselves. If there isn't
one, it'll load from the local directory as always.
This involves new primitives GCPtr and GCAnyPtr which are pointer types
that have finalisers attached. The finalisers are run when the
associated pointer goes out of scope.
In the test, I am assuming that the GC will only be called once, right
at the end. Otherwise, the output isn't guaranteed to be deterministic!
Let's see how this assumption holds...
This is currently Chez only. I think it'll be easy enough to add to
the Racket and Gambit back ends too.
Clash in a reflection test due to conflicting merges. I'd like to find a
way to make the internally generated numbers not matter here (and
elsewhere) but I don't see an obvious way.
Fixes#116. This is the solution Idris 1 took, and while it is a special
case, the syntax does make it explicit (in a way) that the result of the
case is unused - if you mean something other than (), you must now say
so!
helps with readability since these, especially named-IPi, come up a lot
didn't change everything that could need it like PiInfo or BindMode
PiInfo rarely has DefImplicit (so far) and BindMode hasn't come up a lot (so far)
reduced indentation for TTImp Show implementation
Another one from the "stop trying to be clever" files :). Instead of a
continuation for fallthrough in the evaluator, be explicit about whether
there's a result, no match, or evaluation is stuck.
Fixes#70
This is quite fiddly as it the blocks might be in different contexts so
we need to keep track of which variables correspond in the scrutinees of
the blocks. Once that's done, check the terms at the leaves convert,
then check the corresponding variables convert.
This may not be perfect yet, because we only look at case scrutinees to
find correspondence. It might also be a bit slower than it could be, but
at least these checks are quite rare.
Fixes#208 and maybe some others?
Allows quoting a term back to a TTImp. Test reflection007 shows one
possible use for this, building a reflected, type safe, representation
of an expression.
So the type of Elab now gives the expected type that's being elaborated
to, meaning that we can run 'check' in the middle of scripts and use the
result.
On the LHS, we want to match against the reflected thing, so FC and
implicits need to turn into match anything patterns, or we won't match
anything at all. This means we can put quoted terms on the LHS, with
pattern variables under ~().
Instead of merely generating a locally unique name, use the existing
code for generating a new unique variable name in the unifier, which is
therefore globally unique.
This invokes a script of type Elab (). %runElan in a term invokes a
script of type Elab TT. The elaborator now pushes in that type, so that
it'll report an appropriate error if you give it a script of the wrong
type.
A %macro must always be fully applied. Whenever the elaborator
encounters a %macro application (except in a function LHS) it evaluates
the application and sends the result to %runElab. So:
%macro
foo : args -> Elab TT
...
def = foo a b c
is equivalent to
foo : args -> Elab TT
...
def = %runElab foo a b c
