(require mzlib/include) | package: compatibility-lib

> NOTE: This library is deprecated; use racket/include, instead.

Similar to scheme/include, but with a different syntax for paths.

> syntax (include path-spec)
> path-spec |  | = |  | string
> |  | | |  | (build-path elem ...+)
> |  | | |  | (lib file-string collection-string ...)
> elem |  | = |  | string
> |  | | |  | up
> |  | | |  | same

Inlines the syntax in the designated file in place of the include expression. The path-spec can be any of the following:

- A literal string that specifies a path to include, parsed according to the platform’s conventions (which means that it is not portable).

- A path construction of the form (build-path elem ...+), where build-path is module-identifier=? either to the build-path export from mzscheme or to the top-level build-path, and where each elem is a path string, up (unquoted), or same (unquoted). The elems are combined in the same way as for the build-path function to obtain the path to include.

- A path construction of the form (lib file-string collection-string ...), where lib is free or refers to a top-level lib variable. The collection-strings are passed to collection-path to obtain a directory; if no collection-stringss are supplied, "mzlib" is used. The file-string is then appended to the directory using build-path to obtain the path to include.

If path-spec specifies a relative path to include, the path is resolved relative to the source for the include expression, if that source is a complete path string. If the source is not a complete path string, then path-spec is resolved relative to the current load relative directory if one is available, or to the current directory otherwise.

The included syntax is given the lexical context of the include expression.

Variants of include analogous to the variants of scheme/include.
