This implements stage1 parser support for anonymous struct literal
syntax (see #685), as well as semantic analysis support for anonymous
struct literals and anonymous list literals (see #208). The semantic
analysis works when there is a type coercion in the result location;
inferring the struct type based on the values in the literal is not
implemented yet. Also remaining to do is zig fmt support for this new
syntax and documentation updates.
This commit also hooks up type coercion (previously called implicit
casting) into the result location mechanism, and additionally hooks up
variable declarations, maintaining the property that:
var a: T = b;
is semantically equivalent to:
var a = @as(T, b);
See #1757
- define zig global cache based on XDG spec:
if env XDG_CACHE_HOME {
"$XDG_CACHE_HOME/zig"
} else {
"$HOME/.cache/zig"
}
- old definition "$HOME/.local/share/zig" is retired
- closes#3573
* delete the std/event/net directory
* `std.event.Loop.waitUntilFdReadable` and related functions
no longer have possibility of failure. On Linux, they fall
back to poll() and then fall back to sleep().
* add some missing `noasync` decorations in `std.event.Loop`
* redo the `std.net.Server` API. it's quite nice now, but
shutdown does not work cleanly. There is a race condition with
close() that I am actively working on.
* move `std.io.OutStream` to its own file to match `std.io.InStream`.
I started working on making `write` integrated with evented I/O,
but it got tricky so I backed off and filed #3557. However
I did integrate `std.os.writev` and `std.os.pwritev` with evented I/O.
* add `std.Target.stack_align`
* move networking tests to `lib/std/net/test.zig`
* add `std.net.tcpConnectToHost` and `std.net.tcpConnectToAddress`.
* rename `error.UnknownName` to `error.UnknownHostName` within the
context of DNS resolution.
* add `std.os.readv`, which is integrated with evented I/O.
* `std.os.preadv`, is now integrated with evented I/O.
* `std.os.accept4` now asserts that ENOTSOCK and EOPNOTSUPP never
occur (misuse of API), instead of returning errors.
* `std.os.connect` is now integrated with evented I/O.
`std.os.connect_async` is gone. Just use `std.os.connect`.
* fix false positive dependency loop regarding async function frames
* add more compile notes to help when dependency loops occur
in determining whether a function is async.
* ir: change an assert to ir_assert to make it easier to find
workarounds for when such an assert is triggered. In this case
it was trying to parse an IPv4 address at comptime.
