branch: externals/rudel
commit 901a96e5342d74003d5620d059ad1deea43dd0da
Author: Stefan Monnier <monnier@iro.umontreal.ca>
Commit: Stefan Monnier <monnier@iro.umontreal.ca>
Adjust code to current cl-generic practices
Delete all `object-print` methods. Use `eieio-object-p` instead of
`object-p`. Use slot names rather than initargs when accessing slots.
Make sure `:initform`s aren't ambiguous.
Remove most obsolete "object name" arguments.
Catch `cl-no-next-method` instead of testing `cl-next-method-p`.
Use `cl-typep` instead of `<classname>-child-p`.
Fix some "docstring wider than 80 characters" warnings, as well as
most "unknown slot" warnings.
Avoid `object-class`.
* jupiter-operation.el (jupiter-insert, jupiter-delete): Move here to
avoid circular dependencies.
* jupiter-nop.el (jupiter-transform) <t jupiter-nop>: New method.
* jupiter-insert.el (jupiter-insert): Move to jupiter-operation.el.
(jupiter-transform): Dispatch on both args.
* jupiter-delete.el (jupiter-delete): Move to jupiter-operation.el.
(jupiter-transform): Dispatch on both args.
* jupiter-compound.el (jupiter-transform) <t jupiter-compound>: New method.
* adopted-operation.el (adopted-insert, adopted-delete): Move here to
avoid circular dependencies.
(adopted-transform): Define the generic function.
* adopted-nop.el (adopted-transform) <t adopted-nop>: New method.
* adopted-insert.el (adopted-insert): Move to adopted-operation.el.
(adopted-transform): Dispatch on both args.
* adopted-delete.el (adopted-delete): Move to adopted-operation.el.
(adopted-transform): Dispatch on both args.
* adopted-compound.el (adopted-transform) <t adopted-compound>:
New method, extracted from adopted-(delete|insert).el.
