This reverts commit b461d07a54.
After some discussion in the team, we've decided that this is too disruptive,
especially because the linker errors are less than helpful. That's a fixable
problem, so we might reconsider this in the future, but revert it for now.
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
Adds a CreateProcessFlags packed struct for all the possible flags to
CreateProcessW on windows. In addition, propagates the existing
`start_suspended` option in std.process.Child which was previously only
used on Darwin. Also adds a `create_no_window` option to std.process.Child
which is a commonly used flag for launching console executables on
windows without causing a new console window to "pop up".
Acts as a replacement for `addSharedLibrary` and `addStaticLibrary`, but
linking mode can be changed more easily in build.zig, for example:
In library:
```zig
const linkage = b.option(std.builtin.LinkMode, "linkage", "Link mode for a foo_bar library") orelse .static; // or other default
const lib = b.addLibrary(.{
.linkage = linkage,
.name = "foo_bar",
.root_module = mod,
});
```
In consumer:
```zig
const dep_foo_bar = b.dependency("foo_bar", .{
.target = target,
.optimize = optimize,
.linkage = .static // or dynamic
});
mod.linkLibrary(dep_foor_bar.artifact("foo_bar"));
```
It also matches nicely with `linkLibrary` name.

Deprecated aliases that are now compile errors:
- `std.fs.MAX_PATH_BYTES` (renamed to `std.fs.max_path_bytes`)
- `std.mem.tokenize` (split into `tokenizeAny`, `tokenizeSequence`, `tokenizeScalar`)
- `std.mem.split` (split into `splitSequence`, `splitAny`, `splitScalar`)
- `std.mem.splitBackwards` (split into `splitBackwardsSequence`, `splitBackwardsAny`, `splitBackwardsScalar`)
- `std.unicode`
+ `utf16leToUtf8Alloc`, `utf16leToUtf8AllocZ`, `utf16leToUtf8`, `fmtUtf16le` (all renamed to have capitalized `Le`)
+ `utf8ToUtf16LeWithNull` (renamed to `utf8ToUtf16LeAllocZ`)
- `std.zig.CrossTarget` (moved to `std.Target.Query`)
Deprecated `lib/std/std.zig` decls were deleted instead of made a `@compileError` because the `refAllDecls` in the test block would trigger the `@compileError`. The deleted top-level `std` namespaces are:
- `std.rand` (renamed to `std.Random`)
- `std.TailQueue` (renamed to `std.DoublyLinkedList`)
- `std.ChildProcess` (renamed/moved to `std.process.Child`)
This is not exhaustive. Deprecated aliases that I didn't touch:
+ `std.io.*`
+ `std.Build.*`
+ `std.builtin.Mode`
+ `std.zig.c_translation.CIntLiteralRadix`
+ anything in `src/`
* `doc/langref` formatting
* upgrade `.{ .path = "..." }` to `b.path("...")`
* avoid using arguments named `self`
* make `Build.Step.Id` usage more consistent
* add `Build.pathResolve`
* use `pathJoin` and `pathResolve` everywhere
* make sure `Build.LazyPath.getPath2` returns an absolute path
On Windows, the command line arguments of a program are a single WTF-16 encoded string and it's up to the program to split it into an array of strings. In C/C++, the entry point of the C runtime takes care of splitting the command line and passing argc/argv to the main function.
https://github.com/ziglang/zig/pull/18309 updated ArgIteratorWindows to match the behavior of CommandLineToArgvW, but it turns out that CommandLineToArgvW's behavior does not match the behavior of the C runtime post-2008. In 2008, the C runtime argv splitting changed how it handles consecutive double quotes within a quoted argument (it's now considered an escaped quote, e.g. `"foo""bar"` post-2008 would get parsed into `foo"bar`), and the rules around argv[0] were also changed.
This commit makes ArgIteratorWindows match the behavior of the post-2008 C runtime, and adds a standalone test that verifies the behavior matches both the MSVC and MinGW argv splitting exactly in all cases (it checks that randomly generated command line strings get split the same way).
The motivation here is roughly the same as when the same change was made in Rust (https://github.com/rust-lang/rust/pull/87580), that is (paraphrased):
- Consistent behavior between Zig and modern C/C++ programs
- Allows users to escape double quotes in a way that can be more straightforward
Additionally, the suggested mitigation for BatBadBut (https://flatt.tech/research/posts/batbadbut-you-cant-securely-execute-commands-on-windows/) relies on the post-2008 argv splitting behavior for roundtripping of the arguments given to `cmd.exe`. Note: it's not necessary for the suggested mitigation to work, but it is necessary for the suggested escaping to be parsed back into the intended argv by ArgIteratorWindows after being run through a `.bat` file.
