This is the manifest file for build.zig scripts. It is named build.zig.zon in order to make it clear that it is metadata specifically pertaining to build.zig.
- build root - the directory that contains
build.zig
String. Required.
This is the default name used by packages depending on this one. For example,
when a user runs zig fetch --save <url>, this field is used as the key in the
dependencies table. Although the user can choose a different name, most users
will stick with this provided value.
It is redundant to include "zig" in this name because it is already within the Zig package namespace.
String. Required.
String. Optional.
This is currently advisory only; the compiler does not yet do anything with this version.
Struct.
Each dependency must either provide a url and hash, or a path.
String.
When updating this field to a new URL, be sure to delete the corresponding
hash, otherwise you are communicating that you expect to find the old hash at
the new URL.
String.
This is computed from the file contents of the directory of files that is
obtained after fetching url and applying the inclusion rules given by
paths.
This field is the source of truth; packages do not come from a url; they
come from a hash. url is just one of many possible mirrors for how to
obtain a package matching this hash.
String.
When this is provided, the package is found in a directory relative to the
build root. In this case the package's hash is irrelevant and therefore not
computed. This field and url are mutually exclusive.
Boolean.
When this is set to true, a package is declared to be lazily fetched. This
makes the dependency only get fetched if it is actually used.
List. Required.
Specifies the set of files and directories that are included in this package.
Paths are relative to the build root. Use the empty string ("") to refer to
the build root itself.
Only files included in the package are used to compute a package's hash.
