Here is the top of a validated JSON katakana data file for Japanese e-learning:
{"katakana": [
{"ucs": "30AB", "utf-8": "E382AB", "kana": "カ", "info": "katakana letter KA"},
{"ucs": "30AC", "utf-8": "E382AC", "kana": "ガ", "info": "katakana letter GA"},
{"ucs": "30AD", "utf-8": "E382AD", "kana": "キ", "info": "katakana letter KI"},
{"ucs": "30AE", "utf-8": "E382AE", "kana": "ギ", "info": "katakana letter GI"},
and here is the Curl:
{let katakana-array:{Array-of Katakana} = {new {Array-of Katakana},
{Katakana "30AB", "E382AB", "カ", "katakana letter KA"},
{Katakana "30AC", "E382AC", "ガ", "katakana letter GA"},
{Katakana "30AD", "E382AD", "キ", "katakana letter KI"},
{Katakana "30AE", "E382AE", "ギ", "katakana letter GI"},
In Curl, both require field definitions for processing - except that the Curl data requres a minimal class definition and a default constructor declaring all fields as being assigned (simple value class).
Of course both could have been reduced to mere arrays of strings, but then the iteration over the data would use no tags or keys. The Curl version is tagged, but internally:
{define-value-class public final Katakana
field private constant ucs-code:String || = "0000"
field private constant utf8-code:String || = "000000"
field private constant kana-char:String || = {String '\u5B57'} || "字"
field private constant kana-name:String || = "Ji"
{getter public {ucs}:String
{return self.ucs-code}
}
{getter public {utf-8}:String
{return self.utf8-code}
}
{getter public {katakana}:String
{return self.kana-char}
}
{getter public {character}:String
{return self.kana-name}
}
{constructor {default ucs:String, utf:String, kana:String, info:String}
set self.ucs-code = ucs
set self.utf8-code = utf
set self.kana-char = kana
set self.kana-name = info
}
}
{include "./katakana-unicode.scurl"}
The iterator block accesses each instance as, e.g., val.ucs and so forth.
In fairness, the JSON could have been
{"katakana-array": [
{"katakana": ["ucs": "30AB", "utf-8": "E382AB", "kana": "カ", "info": "katakana letter KA"]},
but it further complicated iterating over the data.
In the Curl applet the Curl data is processed dramatically faster, naturally.
The JSON data can be used anywhere, e.g., by Pharo Smalltalk or jQuery in web page widgets.
Note: the UTF-8 can be used to urlencode: "E382B6" becomes %E3%82%B6 for a URL.
