If we're going to use assert_total. we might as well not have the
distinction between empty and non empty results, which only makes the
code harder to follow.
Also there's some kind of issue which seems to mean the token list can't
be erased if we do that. I will investigate if I can make a smaller
example.
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`
The latest Github Actions windows image contains msys2 so use that.
Also use gcc that comes with the image to save downloading clang.
Skip Racket as it's slow enough already.
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.
