wv-settings🔗ℹ

Settings wrapper used by the webview library.

This module exports the wv-settings% class, which provides a small object-oriented interface over an ini settings backend. Settings are accessed relative to a context.

1 Overview🔗ℹ

A wv-settings% object combines:

an ini settings object
a symbol identifying the settings context

Keys used in this class are symbols.

2 Class: wv-settings%🔗ℹ

class
wv-settings% : class?

superclass: object%

Wraps an ini settings object for one context.

The class delegates all reads and writes to the supplied ini object.

constructor
(new wv-settings%
    [ini ini]
    [wv-context wv-context])
→ (is-a?/c wv-settings%)
  ini : (is-a?/c ini%)
  wv-context : symbol?
Creates a settings wrapper.
ini must provide compatible get and set! methods. wv-context is the context symbol used for contextual settings access.
method
(send a-wv-settings get key
default-value ...) → any/c
  key : symbol?
  default-value : any/c
Returns the value associated with key in the current context.
If no default value is supplied, the call delegates to:
(send ini get wv-context key)
If a default value is supplied, only the first extra argument is used, and the call delegates to:
(send ini get wv-context key default)
method
(send a-wv-settings set! key value) → any/c
  key : symbol?
  value : any/c
Stores value under key in the current context.
Delegates to:
(send ini set! wv-context key value)
method
(send a-wv-settings get/global key
default-value ...) → any/c
  key : symbol?
  default-value : any/c
Returns the value associated with key in the global settings section.
If no default value is supplied, the call delegates to:
(send ini get 'global key)
If a default value is supplied, only the first extra argument is used, and the call delegates to:
(send ini get 'global key default)
method
(send a-wv-settings set/global! key value) → any/c
  key : symbol?
  value : any/c
Stores value under key in the global settings section.
Delegates to:
(send ini set! 'global key value)
method
(send a-wv-settings clone context) → wv-settings%
  context : symbol?
Creates a new wv-settings% object sharing the same ini backend but using context as its context.
method
(send a-wv-settings context) → symbol?
Returns the current context symbol.
