Message-ID: <87u0q0ybxh.fsf@zip.com.au> (raw)
Correction to define-modules #:autoload, it read like the arg was a
single symbol, but it's actually a list.
`#:autoload MODULE SYMBOL-LIST'
Load MODULE when any of SYMBOL-LIST are accessed. For
example,
(define-module (my mod)
#:autoload (srfi srfi-1) (partition delete-duplicates))
...
(if something
(set! foo (delete-duplicates ...)))
When a module is autoloaded, all it's bindings become
available. SYMBOL-LIST is just those that will first trigger
the load.
An autoload is a good way to defer loading a big module until
it's really needed, for instance for faster startup or if it
will only be needed in certain circumstances.
`@' can do a similar thing (*note Using Guile Modules::), but
in that case an `@' form must be written every time a binding
from the module is used.
