Hello,
I am playing with MetaLink, really cool!, but I am having issues that I am unsure if it's some erro or if I am doing something wrong (I am using Pharo 6.1 32 bits in windows.). Consider:
TestMetaLink>>execute UIManager default alert: 'Actual Version'.
And in Playground:
| link |
link := MetaLink new metaObject: [ :object | UIManager default alert: 'Linked Version' ]; selector: #value:; arguments: #(#object); control: #instead.
(TestMetaLink >> #execute) ast link: link. TestMetaLink new execute. link uninstall.
This works as expected, an alert with 'Linked Version' is promped. But then suppose I want to execute the actual node alongside with the linked one considering some condition:
| link choice |
choice := true. link := MetaLink new metaObject: [ :object :selector :arguments | UIManager default alert: 'Linked Version'. choice ifTrue: [ object perform: selector withArguments: arguments]. ]; selector: #value:value:value:; arguments: #(#object #selector #arguments); control: #instead; level: 0.
(TestMetaLink >> #execute) ast link: link. TestMetaLink new execute. link uninstall.
As I understand, level:0 is necessary in order to avoid an infinite loop, but then I get an error:
KeyNotFound: key #RFArgumentsReificationVar not found in Dictionary
Am I doing something wrong? Is that an error?
Hello, Yes, this looks like a bug. I will fix it over the next days. Marcus
