5.1 Public Interface


5.1.1 Special variables

Special Variable: *attribute-processors*

Global registry of attribute processors.

This has to be an EQUALP hash-table with the attribute name as keys and functions that accept two arguments (node attribute-value) as values. Binding this variable can be useful to establish local attributes.

Package

clip.

Source

attr-processors.lisp.

Special Variable: *clipboard-stack*

Template storage stack. When new clipboards are bound, they are pushed onto the stack. Once the binding is left, they are popped off the stack again.

Package

clip.

Source

clipboard.lisp.

Special Variable: *tag-processors*

Global registry of tag processors.

This has to be an EQUALP hash-table with the tag name as keys and functions that accept one argument (the node) as values. Binding this variable can be useful to establish local tags.

Package

clip.

Source

tag-processors.lisp.

Special Variable: *target*

This variable is bound to whatever node is currently being processed.

Package

clip.

Source

attr-processors.lisp.


5.1.2 Macros

Macro: define-attribute-processor (attribute (node value) &body body)

Defines a new attribute processor.

ATTRIBTUE — A symbol or string that matches the attribute to process (case-insensitive) NODE — The current node is bound to this symbol.
VALUE — The value of the attribute is bound to this symbol.
BODY ::= form*

Package

clip.

Source

attr-processors.lisp.

Macro: define-tag-processor (tag (node) &body body)

Defines a new attribute processor.

TAG — A symbol or string that matches the tag name to process (case-insensitive) NODE — The node to process is bound to this symbol
BODY ::= form*

Package

clip.

Source

tag-processors.lisp.

Macro: with-clipboard-bound ((new-clipboard &rest fields) &body body)

Executes the body with the new clipboard on the *CLIPBOARD-STACK*.

If fields are provided, they are set on the NEW-CLIPBOARD in plist fashion as per consecutive SETF. This means that side-effects of an early field set affect later fields. The fields are evaluated before the NEW-CLIPBOARD is pushed onto the *CLIPBOARD-STACK*.

Package

clip.

Source

clipboard.lisp.


5.1.3 Ordinary functions

Function: attribute-processor (attribute)

Returns the processor function for the requested attribute if one is registered. Otherwise returns NIL. See *ATTRIBUTE-PROCESSORS*.

Package

clip.

Source

attr-processors.lisp.

Function: (setf attribute-processor) (attribute)

Sets the attribute-processor bound to the given attribute to the specified function. See *ATTRIBUTE-PROCESSORS*.

Package

clip.

Source

attr-processors.lisp.

Function: check-attribute (node attribute)

Checks whether the given attribute is present on the node.

If it is, the attribute’s value is returned.
Otherwise, an error of type MISSING-ATTRIBUTE is signalled.

See MISSING-ATTRIBUTE

Package

clip.

Source

conditions.lisp.

Function: check-no-unknown-attributes (node &rest known-attributes)

Checks whether there are any unknown attributes present on the node.

If an unknown attribute is present, a warning of type UNKNOWN-ATTRIBUTE is signalled. Otherwise, NIL is returned.

See UNKNOWN-ATTRIBUTE

Package

clip.

Source

conditions.lisp.

Function: check-sole-attribute (node attribute)

Checks whether the given attribute is the only attribute on the node.

If it is not present, or not the only one, an error is signalled. Otherwise, the attribute’s value is returned.

See CHECK-NO-UNKNOWN-ATTRIBUTES
See CHECK-ATTRIBUTE

Package

clip.

Source

conditions.lisp.

Function: clipboard (field)

Shorthand for (CLIP (FIRST *CLIPBOARD-STACK*) FIELD)

Package

clip.

Source

clipboard.lisp.

Function: (setf clipboard) (field)

Shorthand for (SETF (CLIP (FIRST *CLIPBOARD-STACK*) FIELD) VALUE)

Package

clip.

Source

clipboard.lisp.

Function: make-clipboard (&rest fields)

Creates a new clipboard using the specified fields (like a plist).

Package

clip.

Source

clipboard.lisp.

Function: parse-and-resolve (value)

If the passed value is a STRING it is parsed using READ-FROM-STRING and subsequently passed to RESOLVE-VALUE. If it is not a string, the value itself is returned.

Package

clip.

Source

clipboard.lisp.

Function: process (target &rest fields)

Processes all clip markup on the target with the given FIELDS used to initialise the clipboard.

Package

clip.

Source

processor.lisp.

Function: process-attribute (node attribute value)

Processes the specified attribute using the given value. If no attribute processor can be found, nothing is done. See *ATTRIBUTE-PROCESSORS*.

Package

clip.

Source

attr-processors.lisp.

Function: process-attributes (node)

Processes all attributes on the node. See PROCESS-ATTRIBUTE.

Package

clip.

Source

attr-processors.lisp.

Function: process-children (node)

Calls PROCESS-NODE on all childrens of the passed node.

This takes some care to make sure that splicing into the childrens array of the node is possible. However, note that inserting children before the node that is currently being processed will most likely lead to horrors. If such functionality is indeed ever needed (I hope not), this system needs to be rewritten to somehow be able to cope with such scenarios.

Package

clip.

Source

tag-processors.lisp.

Function: process-node (node)

Processes the passed node.

Depending on type the following is done:
PLUMP:ELEMENT PROCESS-TAG is called.
PLUMP:NESTING-NODE PROCESS-CHILDREN is called.
PLUMP:NODE Nothing is done.
T An error is signalled.
Any call to this also increases the *TARGET-COUNTER* regardless of what is done.

Package

clip.

Source

tag-processors.lisp.

Function: process-tag (tag node)

Processes the specified node as the given tag.
If no tag processor can be found, PROCESS-ATTRIBUTES and PROCESS-CHILDREN is called. See *TAG-PROCESSORS*.

Package

clip.

Source

tag-processors.lisp.

Function: process-to-string (target &rest fields)

Same as PROCESS, but automatically performs PLUMP:SERIALIZE on the result to a string.

Package

clip.

Source

processor.lisp.

Function: resolve-attribute (node attr)

Shorthand to resolve the value of an attibute. See RESOLVE-VALUE.

Package

clip.

Source

clipboard.lisp.

Function: tag-processor (tag)

Returns the processor function for the requested tag if one is registered. Otherwise returns NIL. See *TAG-PROCESSORS*.

Package

clip.

Source

tag-processors.lisp.

Function: (setf tag-processor) (tag)

Sets the tag-processor bound to the given tag-name to the specified function. See *TAG-PROCESSORS*.

Package

clip.

Source

tag-processors.lisp.


5.1.4 Generic functions

Generic Function: clip (object field)

Generic object accessor.
If you want to get special treatment of objects or types, define your own methods on this.

Package

clip.

Source

clipboard.lisp.

Methods
Method: clip ((model standard-object) field)

Generic slot accessor.

Method: clip ((model list) field)

Generic alist or plist accessor.

Method: clip ((table hash-table) field)

Generic hash-table accessor.

Method: clip ((board clipboard) field)

Accessor for the clipboard object.

Generic Function: (setf clip) (object field)

Generic object setter.
If you want to get special treatment of objects or types, define your own methods on this.

Package

clip.

Source

clipboard.lisp.

Methods
Method: (setf clip) ((model standard-object) field)
Method: (setf clip) ((model list) field)
Method: (setf clip) ((table hash-table) field)
Method: (setf clip) ((board clipboard) field)
Generic Function: resolve-value (object)

Attempts to resolve the object to a specific value.
This is usually used in combination with READ-FROM-STRING of an attribute value.

Package

clip.

Source

clipboard.lisp.

Methods
Method: resolve-value ((list list))

Handler for lists, aka function calls.

The function call is decided upon the CAR of the list. The following cases are handled:

QUOTE Returns the first argument
FUNCTION Returns the symbol-function of the first argument OR Simulated version of the OR macro.
AND Simulated version of the AND macro.

Otherwise the symbol is looked for in the :CLIP package and then the current *PACKAGE*. If found, the function is applied with all arguments of the list (which are first all individually passed to RESOLVE-VALUE too).

Method: resolve-value ((symbol symbol))

Handler for symbols.
If the symbol is EQL to ’* the *CLIPBOARD* is returned, If the symbol is a keyword the symbol itself is returned, otherwise the value of (CLIPBOARD SYMBOL) is returned.

Method: resolve-value (object)

Default fallback for unrecognized objects; simply returns it.
