Functions

#
resolveInstallPrefix
This function is intended to be called by lib/build_runner.zig, not a build.zig file.
addOptions
Create a set of key-value pairs that can be converted into a Zig source
addTest
Creates an executable containing unit tests.
addModule
This function creates a module and adds it to the package's module set, making
createModule
This function creates a private module, to be used by the current package,
addSystemCommand
Initializes a `Step.Run` with argv, which must at least have the path to the
addRunArtifact
Creates a `Step.Run` with an executable built with `addExecutable`.
addConfigHeader
Using the `values` provided, produces a C header file, possibly based on a
dupe
Allocator.dupe without the need to handle out of memory.
dupeStrings
Duplicates an array of strings without the need to handle out of memory.
dupePath
Duplicates a path and converts all slashes to the OS's canonical path separator.
option
Creates a configuration option to be passed to the build.zig script.
standardTargetOptions
Exposes standard `zig build` options for choosing a target and additionally
parseTargetQuery
Obtain a target query from a string, reporting diagnostics to stderr if the
standardTargetOptionsQueryOnly
Exposes standard `zig build` options for choosing a target.
installArtifact
This creates the install step and adds it to the dependencies of the
addInstallArtifact
This merely creates the step; it does not add it to the dependencies of the
installFile
`dest_rel_path` is relative to prefix path
installBinFile
`dest_rel_path` is relative to bin path
installLibFile
`dest_rel_path` is relative to lib path
addInstallFile
`dest_rel_path` is relative to install prefix path
addInstallBinFile

addInstallLibFile
`dest_rel_path` is relative to lib path
addInstallHeaderFile
`dest_rel_path` is relative to header path
path
References a file or directory relative to the source root.
pathFromRoot
This is low-level implementation details of the build system, not meant to
run
This is a helper function to be called from build.zig scripts, *not* from
lazyDependency
When this function is called, it means that the current build does, in
lazyImport
In a build.zig file, this function is to `@import` what `lazyDependency` is to `dependency`.
dumpBadGetPathHelp
In this function the stderr mutex has already been locked.
makeTempPath
This function is intended to be called in the `configure` phase only.
