2025-07-07std.fmt: breaking API changesAndrew Kelley
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
2024-07-14make zig compiler processes live across rebuildsAndrew Kelley
Changes the `make` function signature to take an options struct, which additionally includes `watch: bool`. I intentionally am not exposing this information to configure phase logic. Also adds global zig cache to the compiler cache prefixes. Closes #20600
2024-07-12std.Build.Step.WriteFile: remove random bytes from cache hashAndrew Kelley
The cache hash already has the zig version in there, so it's not really needed.
2024-07-12std.Build.Step.WriteFile: fix handling of directoriesAndrew Kelley
and add file system watching integration. `addDirectoryWatchInput` now returns a `bool` which helps remind the caller to 1. call addDirectoryWatchInputFromPath on any derived paths 2. but only if the dependency is not already captured by a step dependency edge. The make function now recursively walks all directories and adds the found files to the cache hash rather than incorrectly only adding the directory name to the cache hash. closes #20571
2024-07-12std.Build.Step.WriteFile: extract UpdateSourceFilesAndrew Kelley
This has been planned for quite some time; this commit finally does it. Also implements file system watching integration in the make() implementation for UpdateSourceFiles and fixes the reporting of step caching for both. WriteFile does not yet have file system watching integration.
2024-07-04build: fix WriteFile and addCSourceFiles not adding LazyPath depsJonathan Marler
Adds a missing call to addLazyPathDependenciesOnly in std.Build.Module.addCSourceFiles. Also fixes an issue in std.Build.Step.WriteFile where it wasn't updating all the GeneratedFile instances for every directory. To fix the second issue, I removed all the GeneratedFile instances and now all files/directories reference the steps main GeneratedFile via sub paths.

2024-05-05Run: add output directory argumentsJacob Young
This allows running commands that take an output directory argument. The main thing that was needed for this feature was generated file subpaths, to allow access to the files in a generated directory. Additionally, a minor change was required to so that the correct directory is created for output directory args.
2024-05-05Build: cleanupJacob Young
* `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
2024-05-03Rename Dir.writeFile2 -> Dir.writeFile and update all callsitesRyan Liptak
writeFile was deprecated in favor of writeFile2 in f645022d16361865e24582d28f1e62312fbc73bb. This commit renames writeFile2 to writeFile and makes writeFile2 a compile error.
2024-04-07Document added/updated functionsCarl Åstholm
Also renames `addHeaders` to `addHeadersDirectory` for clarity.

2024-02-02std.Build: implement --host-target, --host-cpu, --host-dynamic-linkerAndrew Kelley
This also makes a long-overdue change of extracting common state from Build into a shared Graph object. Getting the semantics right for these flags turned out to be quite tricky. In the end it works like this: * The override only happens when the target is fully native, with no additional query parameters, such as versions or CPU features added. * The override affects the resolved Target but leaves the original Query unmodified. * The "is native?" detection logic operates on the original, unmodified query. This makes it possible to provide invalid host target information, causing confusing errors to occur. Don't do that. There are some minor breaking changes to std.Build API such as the fact that `b.zig_exe` is now moved to `b.graph.zig_exe`, as well as a handful of other similar flags.
2024-01-01zig build system: change target, compilation, and module APIsAndrew Kelley
Introduce the concept of "target query" and "resolved target". A target query is what the user specifies, with some things left to default. A resolved target has the default things discovered and populated. In the future, std.zig.CrossTarget will be rename to std.Target.Query. Introduces `std.Build.resolveTargetQuery` to get from one to the other. The concept of `main_mod_path` is gone, no longer supported. You have to put the root source file at the module root now. * remove deprecated API * update build.zig for the breaking API changes in this branch * move std.Build.Step.Compile.BuildId to std.zig.BuildId * add more options to std.Build.ExecutableOptions, std.Build.ObjectOptions, std.Build.SharedLibraryOptions, std.Build.StaticLibraryOptions, and std.Build.TestOptions. * remove `std.Build.constructCMacro`. There is no use for this API. * deprecate `std.Build.Step.Compile.defineCMacro`. Instead, `std.Build.Module.addCMacro` is provided. - remove `std.Build.Step.Compile.defineCMacroRaw`. * deprecate `std.Build.Step.Compile.linkFrameworkNeeded` - use `std.Build.Module.linkFramework` * deprecate `std.Build.Step.Compile.linkFrameworkWeak` - use `std.Build.Module.linkFramework` * move more logic into `std.Build.Module` * allow `target` and `optimize` to be `null` when creating a Module. Along with other fields, those unspecified options will be inherited from parent `Module` when inserted into an import table. * the `target` field of `addExecutable` is now required. pass `b.host` to get the host target.

2023-07-30build system: follow-up enhancements regarding LazyPathAndrew Kelley
* introduce LazyPath.cwd_relative variant and use it for --zig-lib-dir. closes #12685 * move overrideZigLibDir and setMainPkgPath to options fields set once and then never mutated. * avoid introducing Build/util.zig * use doc comments for deprecation notices so that they show up in generated documentation. * introduce InstallArtifact.Options, accept it as a parameter to addInstallArtifact, and move override_dest_dir into it. Instead of configuring the installation via Compile step, configure the installation via the InstallArtifact step. In retrospect this is obvious. * remove calls to pushInstalledFile in InstallArtifact. See #14943 * rewrite InstallArtifact to not incorrectly observe whether a Compile step has any generated outputs. InstallArtifact is meant to trigger output generation. * fix child process evaluation code handling of `-fno-emit-bin`. * don't store out_h_filename, out_ll_filename, etc., pointlessly. these are all just simple extensions appended to the root name. * make emit_directory optional. It's possible to have nothing outputted, for example, if you're just type-checking. * avoid passing -femit-foo/-fno-emit-foo when it is the default * rename ConfigHeader.getTemplate to getOutput * deprecate addOptionArtifact * update the random number seed of Options step caching. * avoid using `inline for` pointlessly * avoid using `override_Dest_dir` pointlessly * avoid emitting an executable pointlessly in test cases Removes forceBuild and forceEmit. Let's consider these additions separately. Nearly all of the usage sites were suspicious.
