Hi Andrew: I'm up to my neck in work today, so I'm going to 'dump'
a simple example of a python dictionary that I use for one form,
(the login form, not the 100-field survey).
Here's the python structure:
login_dict = [ # not a true dictionary, but does become one in the process
'email', { 'type':'text',
'attrs':{'llabel': 'Email Address', 'lj': 0, 'size': 30,'req':1,},},
'password', {'type':'text',
'attrs':{'llabel': 'Password', 'lj': 0, 'size': 30,'req':1,},},
] # true and tested data structure
; lj = left justified, llabel = label to left, rj, rlabel ->right etc
; other pseudo-attributes would be 'link (relational tables in database)
; now here is the proposed rebol structure of the same functionality
; UNTESTED!
login-dict: [
email [ ; name, may have to be a string
type "text"
txt[llabel "Email Address" lj 0 req 1] ; text attributes
att[size 30 maxlength 40] ; 'htm attributes
]
password [
type "password"
txt[llabel "Email Address" req 1 lj 2]
att[size 20 maxlength 30]
]
]
; in the case of a set of radio buttons, the 'txt/'att structures
; would be nested in an outer block
; And further 'up the line' either of these data structures might
; be generated (at least in one pass) by parsing a static web form
; or even from a database.
I hope this makes it a little clearer.
BTW: the python dictionary (of the {key: 'value'} structure is a
implementation of a binary tree in the "C" source, and is very fast
at runtime.
Does rebol have anything comparable ("under the hood")?
