the man page for macOS `poll(2)` says, under "bugs", that polling
devices does not work, and indeed, although the current implementation
based on poll(2) does produce output, it does not appear to actually
be polling for this reason; instead the wait is blocking on the `read`
call, causing the macOS user to need to input another character to
exit.
this change introduces a wrapper over macOS's implementation of
`select`, modeled after `std.io.poll` as `select.zig`. it is a compile
error to use `select.zig` when `builtin.os.tag.isDarwin()` is false. a
lightly altered version of `Tty.zig` accompanies this change. it's
certainly possible to incorporate the two into one file; i didn't just
to leave the other one in its original state.
with this change, writing to the pipe correctly exits.
additionally, on macOS, `Thread.setName` must be called from the
thread whose name you wish to set, so I have just commented out that
line.
- Added standard .gitattributes file for Zig projects.
- Reworked build.zig a little, hopefully it's a bit clearer. Also, now zig build will run all steps.
- outer: while in examples was redundant since there's only one loop to break from. switch expressions don't allow breaking from them, so breaking is only for loops, i.e. while and for.
- When returning a struct instance from a function, the compiler infers the return type from function signature, so instead of return MyType{...}; , it's more idiomatic to write return .{...};.
- Logging adds a new line by default, so you don't usually need to write \n like here: log.debug("event: {}\r\n", .{event});.
This is so similar to my vaxis project for go that we'll retain the name
here as well. The two can keep similar APIs and feature sets, but are
used in different languages. Maybe someday libvaxis will export a C api
for even broader use
