^^^^^^^^^^^^^^^
|
||
|
|
|

|
||
|
|
- (regexp ptrn [flags])
|
||
|

|
||
|
|
- (regexp-match re input)
|
||
|

Returns two values: a list of match strings, and a list of match indeces.
|
||
|
|
|
||
|
|
- (regexp-replace re input txt)
|
||
|
|
- (regexp-split re input)
|
||
|

(picrin control)

^^^^^^^^^^^^^^^^

|
|
(picrin dictionary)
|
||
|
|
^^^^^^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
Symbol to Object table. Internally it is implemented on hash-table.
|
||
|
|
|
||
|
|
Note that dictionary is not a weak map; if you are going to make a highly memory-consuming program with dictionaries, you should know that dictionaries keep their bound objects and never let them free until you explicitly deletes bindings.
|
||
|
|
|
||
|
|
- (dictionary)
|
||
|
|
|
||
|
|
Returns a newly allocated empty dictionary. In the future, it is planned to extend this function to take optional arguments for initial key/values.
|
||
|
|
|
||
|
|
- (dictionary? obj)
|
||
|
|
|
||
|
|
Returns #t if obj is a dictionary.
|
||
|
|
|
||
|
|
- (dictionary-ref dict key)
|
||
|
|
|
||
|
|
Look up dictionary dict for a value associated with symbol key. If no object is associated with key, it will raise an error.
|
||
|
|
|
||
|
|
- (dictionary-set! dict key obj)
|
||
|
|
|
||
|
|
If there is no value already associated with key, this function newly creates a binding of key with obj. Otherwise, updates the existing binding with given obj.
|
||
|
|
|
||
|
|
- (dictionary-delete dict key)
|
||
|
|
|
||
|
|
Deletes the binding associated with key from dict. If no binding on dict is associated with key, an error will be raised.
|
||
|
|
|
||
|
|
|
||
|
|
- (dictionary-size dict)
|
||
|
|
|
||
|
|
Returns the number of registered elements in dict.
|
||
|
|
|
||
|
