2 raco link: Library Collection Links

The raco link command inspects and modifies a collection links file to display, add, or remove mappings from collection names to filesystem directories.

For example, the command

  raco link maze

installs a user-specific link for the "maze" collection, mapping it to the "maze" subdirectory of the current directory. Supply multiple directory paths to create multiple links at once, especially with a command-shell wildcard:

  raco link *

By default, the linked collection name is the same as each directory’s name, but the collection name can be set separately for a single directory with the --name flag.

To remove the link created by the first example above, use

  raco link --remove maze

or

  raco link -r maze

Like link-adding mode, removing mode accepts multiple directory paths to remove multiple links, and all links that match any directory are removed. If --name is used with --remove, then only links matching both the collection name and directory are removed.

A function version of the raco link command that always works on a single file—either file if it is a path string, the user-specific collection links file if user? is true, of the installation-wide collection links file if user? is false.

The error-proc argument is called to raise exceptions that would be fatal to the raco link command.

If remove? is true, the result is a list of entries that were removed from the file. If remove? is #f but root? is true, the result is a list of paths for collection roots. If remove? and root? are both #f, the result is a list for top-level collections that are mapped by file and that apply to the running version of Racket; the list is a list of strings for collection names if with-path? is #f, or it is a list of pairs of collection-name strings and complete paths if with-path? is true.
