Question

Am able to load and call the functions but I would like to reload the file after making some corrections.

Cant find either an unload or reload function?

Was it helpful?

Solution

Just use load again.

OTHER TIPS

Unloading is not really possible. It is for example possible to delete a package and thus remove its definitions. But other references to a symbol of that package might still exist.

The typical way to deal with that is to load a file again, as Vijay Mathew mentioned.

It might be helpful that the file loaded is written in such a way that reloading is possible.

A few remarks on reloading:

  • functions/macros will be replaced with the new definition.

  • functions/macros in existing code may not be replaced due to inlining/macro expansion.

  • CLOS classes will be updated, its instances will be lazily updated.

  • Structure definitions will be updated, existing structure instances will not be updated.

  • DEFVAR replaces a value if one doesn't exist. DEFPARAMETER always replaces a value.
