We need to make sure they are inferred again when elaborating methods,
so substitute in a _ in method types before substituting in the explicit
parameters.
In future, it might (probably will) also be useful to allow giving the
implicit parameters explicitly when defining implementations.
Fixes#374
This fixes a thing that's been annoying me in the vim mode. It's usually
something that's left to the editor, but we do all the work for the vim
mode! (This is hard to test conveniently, sorry...)
Apparently the concrete syntax is controversial ("{apples}"
vs. "$oranges"), so I'm just adding a simple DYI version until we
agree on a concrete syntax
This involves updating the bootstrap code since it needs a fix in
interface resolution. It shouldn't affect the Idris2-boot build though,
since it's in the libraries not the Idris2 source.
It's worth delaying in case doing some more work (and some more
interface resolution) can make the type more concrete. This makes
test linear011 work more smoothly, and will help with this sort of
program in general.
A better way, later, would be to try elaborating and delay only if the
type is not yet known. We have the facilities, but it's too fiddly for
me to want to implement it right now...
We need to check below top level too, since there could be holes that
we're happy to resolve by searching. The linearity test added
illustrates a place where this is needed.
Doing this is awkward, for a number of reasons, including 'pure' not
being linear in its argument - there's no guarantee it'll be used
linearly after all - and lack of multiplicity polymorphism. Fortunately
the user doesn't have to know about the ugliness underneath!
We can look at ways to make it less horrible later :). For now, this is
starting to look like something that allows us to write linear protocols
without too much extra machinery on top of IO.
It's okay to use locals once we've applied the default hint itself -
it's just committing to locals too early we want to avoid. This allows
%defaulthint to be more expressive (under the assumption we want it to
be :). But shortly we will need it...)
Conditional variables with timeout in Chez didn't work, so changed to a
consistent meaning of the timeout (microseconds). Also fix linearity of
unsafePerformIO.
The namespace parser was not requiring a minimum indentation and instead
based its indentation on the following line, which meant that a line like:
namespace Foo
foodef : Int
placed foodef into namespace Foo instead of the module's top level.
And so made it unclear when a namespace ends.
* `@generated` is a marked used by Phabricator to mark generated files,
any other marker would do
* it's easier to explore source tree when it's clear which files are sources
and which are generated
