wxyz.core#

Isomorphic JSON widgets

class wxyz.core.Fn(**kwargs: Any)[source]#

Bases: Base

Turns a source into a value

This is a foundational class with a number of implementations throughout wxyz.

The simplest Fn subclass might implement the identity function:

class Identity(Fn):
    def the_function(self, source):
        return source

mode#: whether to execute transformations on the client and/or the kernel

source: any#: the source

the_observer(*_)[source]#: Base observer that updates value and/or error

value: any#: the value produced by evaluating the function

class wxyz.core.JSON(**kwargs: Any)[source]#

Bases: Fn

A JSON parsing functional widget

mode#: whether to execute transformations on the client and/or the kernel

source: any#: the source

the_function(source)[source]#: parse some JSON

the_observer(*_)#: Base observer that updates value and/or error

value: any#: the value produced by evaluating the function

class wxyz.core.JSONPointer(**kwargs: Any)[source]#

Bases: Fn

A JSON pointer resolver

mode#: whether to execute transformations on the client and/or the kernel

source: any#: the source

the_function(source, pointer)[source]#: point at some json

the_observer(*_)#: Base observer that updates value and/or error

value: any#: the value produced by evaluating the function

class wxyz.core.JSONSchema(**kwargs: Any)[source]#

Bases: Fn

A JSON schema validator

mode#: whether to execute transformations on the client and/or the kernel

source: any#: the source

the_function(source, schema)[source]#: validate some JSON

the_observer(*_)#: Base observer that updates value and/or error

value: any#: the value produced by evaluating the function

class wxyz.core.UnJSON(**kwargs: Any)[source]#

Bases: Fn

A JSON dumping functional widget

mode#: whether to execute transformations on the client and/or the kernel

source: any#: the source

the_function(source, indent)[source]#: dump some JSON

the_observer(*_)#: Base observer that updates value and/or error

value: any#: the value produced by evaluating the function
