* all: build: fix sdkPath for relative @src.file
Prior to this commit, the build system heavily assumed that the result
`@src.file` would always be absolute, but this is no longer
guaranteed, likely due to there being no such thing as an "absolute
path" in WASI.
It appears that for normal invocations of `zig build`, it is safe to
assume that `@src.file` is absolute. However, when ZLS uses a custom
`build_runner.zig` to collect build configuration, `@src.file` is
actually relative to the current working directory, at least on my
system. For a while, this led to ZLS completions breaking entirely,
but presently it actually causes ZLS to crash!
The solution is not as simple as using relative `sdkPath` results
as-is, because the build system may attempt to resolve these paths
relative to build root, when the paths are actually relative to the
current working directory.
This leads to a sticky situation: the current working directory is a
runtime concept, but `@src.file` is resolved at compile time. However,
it appears that the build runner does not change current working
directory in between compilation and execution, so it is probably safe
to calculate `sdkPath` using runtime current working directory.
Still, this requires major changes with how `sdkPath` works, since
runtime computation and allocations are required. So pretty much
anything that relied on `sdkPath` being comptime-known has been
refactored in this commit.
The most severe result of this is that, for example, `gpu.pkg` can no
longer be a comptime-known constant: it has to be a runtime function
that takes a `*Builder` and returns a `Pkg`.
This commit deals with usages of `*.pkg` and `sdkPath` within Mach
itself, but projects that depend on Mach such as `mach-examples` will
almost certainly require changes as well.
* all: update README to reflect change in pkg usage

mach/wasmserve
Small web server specifically for serving Zig WASM applications in development
Getting started
Adding dependency
In a libs subdirectory of the root of your project:
git clone https://github.com/machlibs/wasmserve
Then in your build.zig add:
...
const wasmserve = @import("libs/wasmserve/wasmserve.zig");
pub fn build(b: *Builder) void {
...
const serve_step = try wasmserve.serve(exe, .{ .watch_paths = &.{"src/main.zig"} });
const run_step = b.step("run", "Run development web server");
run_step.dependOn(&serve_step.step);
}
