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
Following a fairly detailed discussion on slack, the feeling is
generally that it's better to have a single interface. While precision
is nice, it doesn't appear to buy us anything here. If that turns out to
be wrong, or limiting somehow, we can revisit it later. Also:
- it's easier for backend authors if the type of IO operations is
slightly less restrictive. For example, if it's in HasIO, that limits
alternative implementations, which might be awkward for some
alternative back ends.
- it's one less extra detail to learn. This is minor, but there needs to
be a clear advantage if there's more detail to learn.
- It is difficult to think of an underlying type that can't have a Monad
instance (I have personally never encountered one - if they turns out
to exist, again, we can revisit!)
This addresses the case where you'd see an error of:
Ambiguous elaboration at:
r <- pure []
Possible correct results:
[]
[]
[]
By changing it to:
Possible correct results:
Main.Nil
PrimIO.Nil
Prelude.Nil
The output directory was previously called the executable directory, but I changed it because the output is not always an executable (depending on the code generator).
The code generators can now distinguish between where to place the (temporary) build files and the resulting output files.
We do this when elaborating the data type, but not when adding the
individual constructors, so weren't catching the case of repeated
constructors within the same type. Fixes#338
unelabBinder was losing information for the purpose of displaying names
nicely. This is typically wanted but when working with elabortation it's
useful to have all the information you can get. Things like record field
names would be lost when querying with GetType but are now retained.
