added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API
make std.testing.expectFmt work at compile-time
std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.
Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
- anytype -> *std.io.Writer
- inferred error set -> error{WriteFailed}
- options -> (deleted)
* std.fmt.Formatted
- now takes context type explicitly
- no fmt string
preparing to rearrange std.io namespace into an interface
how to upgrade:
std.io.getStdIn() -> std.fs.File.stdin()
std.io.getStdOut() -> std.fs.File.stdout()
std.io.getStdErr() -> std.fs.File.stderr()
Also remove `@frameSize`, closing #3654.
While the other machinery might remain depending on #23446, it is
settled that there will not be `async`/ `await` keywords in the
language.
* resinator: Only preprocess when the input is an .rc file
* resinator: Fix include directory detection when cross-compiling from certain host archs
Previously, resinator would use the host arch as the target arch when looking for windows-gnu include directories. However, Zig only thinks it can provide a libc for targets specified in the `std.zig.target.available_libcs` array, which only includes a few for windows-gnu. Therefore, when cross-compiling from a host architecture that doesn't have a windows-gnu target in the available_libcs list, resinator would fail to detect the MinGW include directories.
Now, the custom option `/:target` is passed to `zig rc` which is intended for the COFF object file target, but can be re-used for the include directory target as well. For the include directory target, resinator will convert the MachineType to the relevant arch, or fail if there is no equivalent arch/no support for detecting the includes for the MachineType (currently 64-bit Itanium and EBC).
Fixes the `windows_resources` standalone test failing when the host is, for example, `riscv64-linux`.

These conversion routines accept a `round` argument to control how the
result is rounded and return whether the result is exact. Most callers
wanted this functionality and had hacks around it being missing.
Also delete `std.math.big.rational` because it was only being used for
float conversion, and using rationals for that is a lot more complex
than necessary. It also required an allocator, whereas the new integer
routines only need to be passed enough memory to store the result.
We have no control over memory usage on arbitrary systems in the wild. But we
would still like to get the warnings so we can adjust the values based on
observations in the official ZSF CI.
Closes#23254.
Closes#23638.
In a compiler built with debug extensions, pass `--debug-incremental` to
spawn the "incremental debug server". This is a TCP server exposing a
REPL which allows querying a bunch of compiler state, some of which is
stored only when that flag is passed. Eventually, this will probably
move into `std.zig.Server`/`std.zig.Client`, but this is easier to work
with right now. The easiest way to interact with the server is `telnet`.
Nothing interesting here; literally just the bare minimum so I can work on this
on and off in a branch without worrying about merge conflicts in the non-backend
code.
It's incorrect to ever set `include_reference_trace` here, because the
compiler has already given or not given reference traces depending on
the `-freference-trace` option propagated to the compiler process by
`std.Build.Step.Compile`.
Perhaps in future we could make the compiler always return the reference
trace when communicating over the compiler protocol; that'd be more
versatile than the current behavior, because the build runner could, for
instance, show a reference trace on-demand without having to even invoke
the compiler. That seems really useful, since the reference trace is
*often* unnecessary noise, but *sometimes* essential. However, we don't
live in that world right now, so passing the option here doesn't make
sense.
Resolves: #23415
The last Intel Quark MCU was released in 2015. Quark was announced to be EOL in
2019, and stopped shipping entirely in 2022.
The OS tag was only meaningful for Intel's weird fork of Linux 3.8.7 with a
special ABI that differs from the regular i386 System V ABI; beyond that, the
CPU itself is just a plain old P54C (i586). We of course keep support for the
CPU itself, just not Intel's Linux fork.
* This has not seen meaningful development for about a decade.
* The Linux kernel port was never upstreamed.
* The glibc port was never upstreamed.
* GCC 15.1 recently deprecated support it.
It may still make sense to support an ILP32 ABI on AArch64 more broadly (which
we already have the Abi.ilp32 tag for), but, to the extent that it even existed
in any "official" sense, the *GNU* ILP32 ABI is certainly dead.
* If a function prototype is declarated inside a function, do not
translate it to a top-level extern function declaration. Similar to
extern local variable, just wrapped it into a block-local struct.
* Add a new extern_local_fn tag of aro_translate_c node for present
extern local function declaration.
* When a function body has a C function prototype declaration, it adds
an extern local function declaration. Subsequent function references
will look for this function declaration.
`--fetch` flag now has additional optional parameter, which specifies
how lazy dependencies should be fetched:
* `needed` — lazy dependencies are fetched only if they are required
for current build configuration to work. Default and works same
as old `--fetch` flag.
* `all` — lazy dependencies are always fetched. If `--system` flag
is used after that, it's guaranteed that **any** build configuration
will not require additional download of dependencies during build.
Helpful for distro packagers and CI systems:

If none is passed, behaviour is same as if `needed` was passed.

When determining the type of RC compiler, meson passes `/?` or `--version` and then reads from `stdout` looking for particular string(s) anywhere in the output.
So, by adding the string "Microsoft Resource Compiler" to the `/?` output, meson will recognize `zig rc` as rc.exe and give it the correct options, which works fine since `zig rc` is drop-in CLI compatible with rc.exe.
This allows using `zig rc` with meson for (cross-)compiling, by either:
- Setting WINDRES="zig rc" or putting windres = ['zig', 'rc'] in the cross-file
+ This will work like rc.exe, so it will output .res files. This will only link successfully if you are using a linker that can do .res -> .obj conversion (so something like zig cc, MSVC, lld)
- Setting WINDRES="zig rc /:output-format coff" or putting windres = ['zig', 'rc', '/:output-format', 'coff'] in the cross-file
+ This will make meson pass flags as if it were rc.exe, but it will cause the resulting .res file to actually be a COFF object file, meaning it will work with any linker that handles COFF object files
Example cross file that uses `zig cc` (which can link `.res` files, so `/:output-format coff` is not necessary) and `zig rc`:
```
[binaries]
c = ['zig', 'cc', '--target=x86_64-windows-gnu']
windres = ['zig', 'rc']
[target_machine]
system = 'windows'
cpu_family = 'x86_64'
cpu = 'x86_64'
endian = 'little'
```
This commits adds the following distinct integer types to std.zig.Ast:
- OptionalTokenIndex
- TokenOffset
- OptionalTokenOffset
- Node.OptionalIndex
- Node.Offset
- Node.OptionalOffset
The `Node.Index` type has also been converted to a distinct type while
`TokenIndex` remains unchanged.
`Ast.Node.Data` has also been changed to a (untagged) union to provide
safety checks.
