To be able to use `C` functions for both Scheme and RefC: it was
not possible for `Buffer` before this PR.
As an example, `writeBufferData` and `readBufferData` functions are
removed: generic C backend implementations are used instead.
While the discussion about how to refactor test framework is not
finished (#1654), make this change: move `rm -rf build` in the
beginning of the test. For these reasons:
* it is useful to inspect the contents of the `build` directory
especially after the test failure
* if build crashes mid-test (e.g. process killed), next run should
not be affected by the `build` directory from the previous run
```
IDRIS2_VERIFY(cond, message_format, ...)
```
When condition is false, crash.
Used in native functions where correct error handling is hard or
not impossible.
For example, `malloc` rarely fails, but if it fails, better crash
with clear error message than spend time debugging null pointer
dereference.
* add `strerror` function
* move `getErrno` to `System.Errno`
* use `strerror` in `Show FileError`
* on node there's no access to `strerror`, so `strerror` just converts the number to string
Ideally we'd have a complete incremental build in CI, but that could be
a bit fiddly to set up at the moment (updating bootstrap code might make
it easier). This tests that the basic facilities work, though - there's
a lot can go wrong even in a small test like this, trust me, I have made
those mistakes :).
This involves making 'unelab' aware of nested names so that it can
remove the parameters from names in the current block. It's a bit of a
hacky solution, but it is also the easiest one.
Ideally we'd build the getter types directly, rather than using unelab,
but that's one to save for another time.
Fixes#1482
Github Action status are based on workflows, not jobs. When #1645 was
merged, it changed multiple workflows into 1 workflow with multiple
jobs. This meant several badges on the README were now linking to
workflows which don't exist. This change makes a badge for the new
single workflow which does exist.
While it would probably be better to have statuses per job, I think the
only way to achieve that would be with an extra action like
https://github.com/marketplace/actions/bring-your-own-badge. So I'll
just stick with this minor fix for now.
Convert `App.Control.Exception` interface to an alias to `HasErr`.
Probably `Exception` interface need to be deprecated or removed.
Note similar problem exists with `PrimIO` calling `PrimIO, Exception`,
also need to be fixed.
Fix this scenario:
```
throwBoth : Has [Exception String, Exception Int] es => App es ()
throwOne : Has [Exception Int] es => App es Int
throwOne {es} = handle {err = String} {e = es} throwBoth (\r => pure 1) (\e => pure 3)
```
With this commit it works, before this commit it failed with:
```
Error: While processing right hand side of throwOne. Can't find an implementation for Exception Int (String :: es).
TestException.idr:8:48--8:57
|
8 | throwOne {es} = handle {err = String} {e = es} throwBoth (\r => pure 1) (\e => pure 3)

```
... instead of `bootstrap` which contains source files. Make it easier to understand
how build works, and in particular, which files are sources and
which files are generated.
We inline some holes when solving them if they pose no risk to breaking
sharing, since this can speed up a few things. But if the hole was
originally a user name, we might want to refer to it, and inlining it
menas we can't since it won't be saved to disk.
