Classic ASP Orderly compiler

Filed Under: ASP, AXE, Framework, Javascript, VBScript

I believe that with today's release the ASP Xtreme Evolution Framework reaches a real maturity to handle JSON. ORDERLY.ASP leverages the power of the Orderly descriptors to your Classic ASP application. Although it's bundled with the AXE, it's modularized enough to work alone for the Orderly.parse method, which returns the JSONSchema subset, or in ensemble with JSON2.ASP which enables Orderly.compile to stringify the JSONSchema representation.

The name behind this release is Zach Carter which made Orderly.js some months ago and keep updating the project since then. The only effort from my part was to document it in the AXE way and write some examples.

Here are some examples of how to use it:

Retriving the JSONSchema subset from an orderly source

<script language="javascript" runat="server" src="/lib/axe/Parsers/orderly.asp"></script>

dim source : source = join(array( _
    "object {", _
    "  string name;", _
    "  string description?;", _
    "  string homepage /^http:/;", _
    "  integer {1500,3000} invented;", _
    "}*;" _
), vbNewline)

dim Schema : set Schema = Orderly.parse(source)
Response.write( typename( Schema ) & vbNewline )
set Schema = nothing




Checking the JSONSchema stringified representation

<script language="javascript" runat="server" src="/lib/axe/Parsers/orderly.asp"></script>
<script language="javascript" runat="server" src="/lib/axe/Parsers/json2.asp"></script>

dim source : source = join(array( _
    "object {", _
    "  string name;", _
    "  string description?;", _
    "  string homepage /^http:/;", _
    "  integer {1500,3000} invented;", _
    "}*;" _
), vbNewline)

Response.write( Orderly.compile(source) & vbNewline )



    "type": "object",
    "properties": {
        "name": {
            "type": "string"
        "description": {
            "type": "string",
            "optional": true
        "homepage": {
            "type": "string",
            "pattern": "^http:"
        "invented": {
            "type": "integer",
            "minimum": 1500,
            "maximum": 3000
    "additionalProperties": true

Classic ASP JSON Revisited

Filed Under: ASP, AXE, Framework, Javascript, VBScript

UPDATE: Kate Osipova kindly made a Polish version of this article. Thanks Kate.

Hi everybody! I'm currently working on three projects using AXE (ASP Xtreme Evolution) Framework and because of their high dependency on JSON I've revisited the topic Classic ASP JSON support. The great news about it is that I found Troy Forster JSON2.ASP a really promising way to work with it. Despite the work being incomplete in terms of functionality, it used a really elegant way to READ the JSON in a fancy native looking way. Plus, the library was based on the Douglas Crockford json2.js meaning it's engine is really strict to the standards.

Because of the AXE philosophy of embrace and use the great ideas born around the world in a real collaboration environment of all languages, I felt really tempted to adopt the original work of the JSON author himself and augment the AXE Framework functionality with this little piece of gold. But I couldn't replace, also it wasn't a smart move in terms of compatibility, my old full featured JSON.ASP class with other that would restrict the freedom to manipulate the Javascript object by my own will.

And that's why I coded my own version of JSON2.ASP which instantly became an integrated piece of AXE. It provides all the functionalities from the Troy Forster work but goes beyond enabling developers to augment the object with booleans, numbers, strings, arrays (using ASP safeArrays notation) and even another objects. Plus I implemented a keys method in the Object.prototype which allows the enumeration of the object keys (this modification is fine and it's also standard in ECMAScript 5) which means that it doesn't matter in which language you are programming (Ruby, Python, VBScript etc) you can use the for each loop in same way that it's available for the language in ASP.

Here are some examples of how to use it:

Reading data from JSON

<script language="javascript" runat="server" src="/lib/axe/Parsers/json2.asp"></script>

dim Info : set Info = JSON.parse(join(array( _
    "{", _
    "  ""firstname"": ""Fabio"",", _
    "  ""lastname"": ""Nagao"",", _
    "  ""alive"": true,", _
    "  ""age"": 27,", _
    "  ""nickname"": ""nagaozen"",", _
    "  ""fruits"": [", _
    "    ""banana"",", _
    "    ""orange"",", _
    "    ""apple"",", _
    "    ""papaya"",", _
    "    ""pineapple""", _
    "  ],", _
    "  ""complex"": {", _
    "    ""real"": 1,", _
    "    ""imaginary"": 2", _
    "  }", _
    "}" _
Response.write(Info.firstname & vbNewline) ' prints Fabio
Response.write(Info.alive & vbNewline) ' prints True
Response.write(Info.age & vbNewline) ' prints 27
Response.write(Info.fruits.get(0) & vbNewline) ' prints banana
Response.write(Info.fruits.get(1) & vbNewline) ' prints orange
Response.write(Info.complex.real & vbNewline) ' prints 1
Response.write(Info.complex.imaginary & vbNewline) ' prints 2
' You can also enumerate object properties ...
dim key : for each key in Info.keys()
    Response.write( key & vbNewline )
' which prints:
' firstname
' lastname
' alive
' age
' nickname
' fruits
' complex
set Info = nothing


Building a JSON

<script language="javascript" runat="server" src="/lib/axe/Parsers/json2.asp"></script>

dim Info : set Info = JSON.parse("{""firstname"":""Fabio"", ""lastname"":""Nagao""}")
Info.set "alive", true
Info.set "age", 27
Info.set "nickname", "nagaozen"
Info.set "fruits", array("banana","orange","apple","papaya","pineapple")
Info.set "complex", JSON.parse("{""real"":1, ""imaginary"":1}")
Response.write( JSON.stringify(Info, null, 2) & vbNewline ) ' prints the text below:
'  "firstname": "Fabio",
'  "lastname": "Nagao",
'  "alive": true,
'  "age": 27,
'  "nickname": "nagaozen",
'  "fruits": [
'    "banana",
'    "orange",
'    "apple",
'    "papaya",
'    "pineapple"
'  ],
'  "complex": {
'    "real": 1,
'    "imaginary": 1
'  }
set Info = nothing

github/nagaozen screenshot

Better late than never! From now on, all my recent open-source contributions will be available at my github.com account. The current projects are:

  • ASP Xtreme Evolution (my ASP framework)
  • Exuberant-ctags (updates to make it's ASP parsing better)
  • Gedit-* (a lot of good things for gedit)
  • GTKSourceView-2.0 (updates to add/enhance language.specs)
  • jquery-vs-mootools (this one is an interesting article I translated)

Although this blog isn't being informative and updated as I think it should be, I'm currently very active and developing a lot of things but not writing much about it. Watching my git account will help you to keep the track of the latest updates in my software development. Enjoy!

Logomark and Icons for AXE

Filed Under: AXE, Design, Framework, Standards

Almost a year has been passed from the first release of AXE and from that to today the project still haven’t it’s own logomark or icons to be used as faveicon. But today, I spent my morning trying to solve this issue. Look, I’m no professional designer, but did my best in this task and liked the result. For the icons I tried to make it compatible with the Tango Icon Guidelines to guarantee a good contrast for both dark and bright backgrounds. I would love to know what you all like or dislike about it. Here’s the final art:

ASP Xtreme Evolution logo

Well, about the new version of AXE, I’m a bit busy working on another project and have no time to polish it. But the enhancements are huge and I hope to have a new version in the next 1 or 2 months.

Textmate theme to Notepad++ styler

Filed Under: Application, ASP, Framework, Notepad++, Optimization, Server, Services

Everybody knows that when I’m at Windows my favorite editor is Notepad++. It’s an opensource source code ( opensource source code – I liked it! ) editor which supports serveral programming languages and has a bunch of interesting features like:

  • Auto-completion
  • Snippets
  • Multi-Document
  • Multi-View
  • Regular Expression Search/Replace
  • Plugins interface

Although it also support customized Syntax Highlighting there aren’t too many options available… But this ends today…

Goodbye old school javascript

Filed Under: Client, Framework, Javascript, Mootools, Optimization

There are times in the life when you realise that the world has really changed and the things that was once so important to you doesn’t matter anymore. This is the case of my old dithered-extended quirksmode javascript library. It cost me years to enhance and extend but nothing more makes sense in a better standardized world.
