This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

addOutputDirectoryArg2

Doc Source

Public Function

std.Build.Step.Run.addOutputDirectoryArg2

pub fn addOutputDirectoryArg2(
    run: *Run,
    basename: []const u8,
    options: PathArgOptions,
) std.Build.LazyPath

Provides a directory path as a command line argument to the command being run. Asserts basename is not empty.

For example, a prefix of "-o" and basename of "output_dir" will result in the child process seeing something like this: "-ozig-cache/.../output_dir"

The child process will see a single argument, regardless of whether the prefix or basename have spaces.

The returned std.Build.LazyPath can be used as inputs to other APIs throughout the build system.

addDirectoryArg - for input directories given to the child process

Params

run: *Run
basename: []const u8
options: PathArgOptions
