Re: [Pharo-users] [Iliad] raw HTML in Iliad

by Steven Costiou

Hi, i think just doing e html: '<some html>' also works. Elements should not be instantiated like you do, there is an interface for each element that can be called on "e". e div, e html:, e h1:, etc. The interface instantiates the right class behind. You can find this somewhere in the core classes, but i don"t remember where and i can't check right now. Steven.

Re: [Pharo-users] canonical way to convert Symbol into Class (retrieve class by its name)

by Marcus Denker

Sometimes I think we should treat globals more in a âlate boundâ fashion. e.g. right now we say that âUndeclaredâ vars are to be avoided at any cost. But we could just treat them like we treat messages that are send that do not exist. Forcing â#classNamed: â for all unknown globals is a bit similar than forcing to use âperform:â for all unknown selectors. e.g. why have Smalltalk at: #SomeClass and react to it if you could instead reason on the fact that a variable is not bound (yet). SomeGlobal ifUndefined: [ ]. This way we would not obscure the fact that we are accessing a global and we model explicitly the state if it is bound or not. Would that no be better than hiding it behind an API to look up symbols?

[Iliad] raw HTML in Iliad

by Siemen Baader

Hi all, is there a way to render raw HTML from Iliad widgets, or perhaps mustache templates?

Is it possible do it with Seaside & Reef instead? -- Siemen
