Re: [Pharo-users] MetaLink>>level: failing?

Oct. 31, 2018

      Thanks! Is there an issue on fogbuzz where I can be notified of resolution?
Do you need me to create it?

After that how can update the code? Software update is safe or should I
create a new image?

regards,
Vitor

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.
