(picrin regexp)
|
|
---------------
|
|
|
|
(regexp ptrn [flags])
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Compiles pattern string into a regexp object. A string flags may contain any of #\g, #\i, #\m.
|
|
|
|
(regexp? obj)
|
|
^^^^^^^^^^^^^
|
|
|
|
Judges if obj is a regexp object or not.
|
|
|
|
(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)
|
|
----------------
|
|
|
|
Delimited control operators.
|
|
|
|
(reset h)
|
|
^^^^^^^^^
|
|
|
|
(shift k)
|
|
^^^^^^^^^
|
|
|
|
(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.
|
|
|
|
