[REBOL] Re: Parse rules as data

From: brett::codeconscious::com at: 28-Jun-2001 1:05

Hi Joel, Thanks for your reply. The idea you think I had appears not to be the one I think I had. But you're most welcome to pursue the former, though my interest is actually in the latter. The latter being as follows in example form: author-index: context [ author-entry: [author author-rebsite] author: [string!] author-rebsite: [url!] model*: [ any author-entry ] content*: [ "Brett Handley" "Joel Neely" "Allen Kamp" ] ] So I can do:
>> parse author-index/content* author-index/model*
== true Then I'd like to provide a new model and have content "calculated" for me doing something like: rebsite: transform author-index rebsites-spec hints-spec where rebsites-spec is rebsite-spec: context [ reblink: ['folder linkurl 'info author] author: [string!] linkurl: [url!] model*: [ any reblink ] ] and hint-spec contains the magical transformation dialect that makes it all possible :) author-entry -> reblink author -> author author-rebsite -> linkurl So for example I might end up with something like this: rebsites: context [ reblink: ['folder linkurl 'info author] author: [string!] linkurl: [url!] model*: [ any reblink ] content*: [ folder info "Brett Handley" folder info "Joel Neely" folder info "Allen Kamp" ] ] and again I can do:
>> parse rebsites/content* rebsites/model*
== true So I guess I'm wondering if some function 'transform and some fantastic transformation dialect will be more economical than just writing the transformation directly in straight Rebol code. Should I go back to dreaming? Maybe the data generator will be more useful :) Brett.
