How to edit /View mezzanine functions ?

 [1/7] from: jasonic:panix at: 19-Nov-2001 0:00


Want to quickly change /View request-color widget.
>> source request-color
Tried some cutnpaste into a new file of my own... load, do, attached to buttons => nothing doing :-( What's the basic trick for doing this kind of learn/edit ? thanks ./Jason

The problem is that request-color is defined somewhere deep in vid context-land. :) And this means that some words maybe not accessible in the global context. The first one I see is color-lay:
>> color-lay
** Script Error: color-lay has no value ** Near: color-lay When we just redefine request-color, its function body block has been defined in the global context. This means it can no longer color-lay (also defined somewhere in vid land). This could help you insert second :request-color [print "hello"] but if you try to use words like color-lay that are not defined in the global context (like color-lay) then you will run into trouble. I think this could work if I knew in which context request-color was defined: insert second :request-color bind [ if none? :color-lay [print "hi"] ] 'where-the-heck? I will need to look through the system object for a while to find where the heck the context is. I'd like to make a search tool for that sort of thing. Anton.

Hi Jason, Anton described the source of your trouble. OTOH, the words "know" their context (As has been described in http://www.sweb.cz/LMecir/contexts.html For Anton: see the IN-OBJECT? function, which can be used for Words, although not for Set-words, etc.) while they aren't converted to strings. That means, that you can use the blocks: spec: third :request-color body: second :request-color After editing the block using INSERT, CHANGE, PICK etc. you can create a new version of request-color e.g. like: new-request-color: func (load mold spec) body Cheers Ladislav <<Anton>> The problem is that request-color is defined somewhere deep in vid context-land. :) And this means that some words maybe not accessible in the global context.

Hi Ladislav (and contributors), I just ran through your document (essay?) on words, contexts and bindings... And I am humbled... I never considered myself a master regarding this aspect of rebol, but now I realize many things I did not quite "picture"... Although I'll have to reference this a few times again, in order to absorb half of it... I am now able to thread some new aspects of reboling with a little bit more assurance A great read.... thanks for researching and compiling this long list of intricaties. I'm almost affraid of what I'll find next... :-D -MAx

Anton, Ladislav aah. thanks for both answers. opened my eyes to another cool strange level of REBOL. I don't understand it yet. But you've shown me the path.. Jason: [heading off for the interpreter after breakfast to experiment with contexts]

Hi, Such search function is being developed in RIDE, it helped me to find, 'req-funcs/req-color/color-lay'. HTH Ammon
