- Added 'binding.Require', 'binding.Obtain', 'binding.Make', and |
| |
'binding.Delegate'. *ALL* other binding types are now DEPRECATED, and will |
| |
go away before 0.5 beta is released: |
| |
|
| |
'requireBinding("info")' -- use 'Require("info")' |
| |
|
| |
'delegateTo("attr")' -- use 'Delegate("attr")' |
| |
|
| |
'New(type)' -- use 'Make(type)' |
| |
|
| |
'New("module.type")' -- use 'Make("module.type")' |
| |
|
| |
'bindTo(key)' -- use 'Obtain(key)' |
| |
|
| |
'Constant(value)' -- use 'Make(lambda: value)' |
| |
|
| |
'Acquire(key)' -- use 'Obtain(key, offerAs=[key])' |
| |
|
| |
'Copy(value)' -- use 'Make(lambda: <expr to copy value>)' |
| |
|
| |
'whenAssembled(func)' -- use 'Make(func, uponAssembly=True)' |
| |
|
| |
'bindSequence(key1,key2,...)' -- use 'Obtain([key1,key,...])' |
| |
|
| |
'bindToProperty(x,y)' -- use 'Obtain(PropertyName(x),default=y)' |
| |
|
| |
'bindToParent()' -- use 'Obtain("..")' |
| |
|
| |
'bindToSelf()' -- use 'Obtain(".")' |
| |
|
| |
'bindToUtilities()' -- no replacement; let me know if you're using this. |
| |
|
| |
Note that 'Make' and 'Obtain' also support sequences of recipes and keys, |
| |
and in those cases will produce a sequence of the results from those recipes |
| |
or keys. Also, 'Make' will accept no-argument and one-argument callables, |
| |
where 'Once' always required three-argument functions. This should make it |
| |
a lot easier to write short binding functions. |
| |
|
| |
Also, note that the 'activateUponAssembly' keyword is now 'uponAssembly', |
| |
and 'isVolatile' is now 'noCache'. (The old names will work as keyword |
| |
arguments until the alpha 4 development cycle begins.) The |
| |
'binding.IActiveDescriptor' interface also changed as a result of this. |
| |
Last, but not least, a 'binding.IRecipe' interface was added, to support the |
| |
new 'binding.Make' type. |
