  1. Yahoo! UI better dragdrop constructors

    peter.michaux.ca (Nov 1 2008) YUI Explore Article

    I like the Yahoo! UI dragdrop library. It does many great things. Unfortunately, the class hierachy, constructors and inheritance do not allow for proper encapsulation or easy subclassing. (Read Full Article)

  2. How I write JavaScript Widgets

    peter.michaux.ca (Oct 24 2008) Explore Article

    Improving the structure of the code I write is an ongoing concern. Over the last while, I feel I've settled in to how I write HTML/CSS/JavaScript widgets and find the pattern repeating itself over and over again. The code example below is a simple little logger widget. It appends messages to a list and has a clear link to delete all the recorded messages. (Read Full Article)

  3. Xpkg: Generic Package Managment Software

    peter.michaux.ca (Aug 27 2008) Explore Article

    Many projects benefit from package-based distribution with dependencies. Famously, Perl has CPAN and Debian has apt. It can be argued these two projects are alive and successful because of CPAN and apt. Various packages can be downloaded from central server package repositories and installed on a local machine. If one package has declared dependencies on other packages then those other packages are installed also. Many package management systems are quite ... (Read Full Article)

  4. Comment on Simple Effects Plugins by Peter

    Learning jQuery (Aug 21 2008) jQuery Explore Article

    Simple Effects Plugins jQuery has a nice selection of core animation effects, such as .show('speed') and .hide('speed'), .slideUp() and .slideDown(), and .fadeIn() and .fadeOut(). It even has a couple methods for toggling effects — the aptly named .toggle('speed') and .slideToggle(). All of these methods have optional speed, easing, and callback arguments — although a couple are special cases. The .show() and .hide() methods, when used without a speed, will immediately ...

  5. Fork v0.2 client-side JavaScript planning discussions

    peter.michaux.ca (Jul 29 2008) Explore Article

    I've been working on version 0.2 of the Fork client-side JavaScript library. I released version 0.1.1 almost a year an a half ago and have been using it in production without incident ever since. Along with some API changes, the truly fundamental goal for version 0.2 is making it easier to use robust feature testing at the application levels built on top of the Fork library. The mainstream client-side JavaScript ... (Read Full Article)

  7. Module Pattern Provides No Privacy...at least not in JavaScript(TM)

    peter.michaux.ca (Jun 26 2008) Explore Article

    The module pattern has been discussed many times and has shown how ECMAScript has the ability to encapsulate data as "private" variables by using closures. Today, in a comment on my blog, a reader, haysmark, points out that Mozilla's JavaScript(TM), the implementation in Firefox, has a second argument extension to eval that allows external code to spy on otherwise private variables. Try the examples below in Firefox. (Read Full Article)

  9. "JavaScript: The Good Parts", built-in object augmentation and namespacing

    peter.michaux.ca (Jun 18 2008) Prototype Explore Article

    I've read and am rereading Douglas Crockford's JavaScript: The Good Parts. It is a thought provoking book. I think he has achieved one of his stated goals to "start you on process of discovering the ways those components can be put together" where "those" refers to the good parts of JavaScript. If you have followed Douglas' writing online and watched his videos you will likely be familiar with the majority ... (Read Full Article)

  10. JavaScript OOP: encapsulation, durable objects, parasitic inheritance and the decorator pattern

    peter.michaux.ca (Jun 16 2008) Explore Article

    I've been working to eliminate this and its associated complexity from my JavaScript vocabulary. I haven't written an articulate blog post about the difficulties this causes but there are many and perhaps I will write that article some day. I've gone on and off with my quest over time and made another push this past week to rid my life of this. I think that after just over two years ... (Read Full Article)

  11. JavaScript Widgets Without "this"

    peter.michaux.ca (Jun 14 2008) Explore Article

    I put this on my list of JavaScript Warning Words and raised some eyebrows. I have been working to eliminate this from my code both as an exercise to understand closures better and also because this does causes problems. This article shows programming a toggle widget both with and without this (Read Full Article)

  15. Xjs 0.0.2 Release

    peter.michaux.ca (May 31 2008) Explore Article

    Work on xjs continues. This week I chose certain core modules, added missing bits of API that will be generally useful, added documentation and unit tests. A few of the modules are virtually finished and if they were stand alone would be almost ready to be tagged 1.0. The whole xjs package is not there yet but things are moving along well.

  16. Google Libraries API

    peter.michaux.ca (May 28 2008) Explore Article

    Google Libraries API now serves common libraries like Dojo and jQuery all minified and gzipped and ready to go. Yahoo has been doing this with YUI for quite a while now and AOL with Dojo. The idea is that if enough sites are using the centralized Google libraries then when a user arrives to your site there is a chance the library is already cached in the user's browser. This ...

  19. Xjs 0.0.0 "Feet Wet" Release

    peter.michaux.ca (May 18 2008) Explore Article

    This week I've worked on the module system: automatically packaging modules for distribution, indexing modules on a central CPAN-like site, and easily installing a module and its dependencies from the central site. To do this I had to separate the core distribution of xjs (e.g. JavaScript shell, xmake, File) from the extra modules (e.g. Synergy, PostgreSQL, YUICompressor). This decoupling is a great step in getting ready for other developers to ... (Read Full Article)

  21. module management: Cpan, Gems, and xjs

    peter.michaux.ca (May 14 2008) Explore Article

    The past few evenings, I've been working on an xjs module management and distribution system. There is no question in my mind that CPAN is the gold standard and the reason that Perl persists today. But Perl and CPAN are a getting a little older and newer systems have come along to try to improve on CPAN so it is worth looking at what these newer systems have to offer. ... (Read Full Article)

  22. ParseArgs xjs module

    I've added a new xjs module called ParseArgs for parsing arguments to a script. Parsing arguments, even with argument parsing libraries in other scripting languages, is not fun. I think that the ParseArgs Module should make the process relatively painless in most situations. (Read Full Article)

  24. Client-Server Code Sharing: putting the "synergy" in Synergy

    peter.michaux.ca (May 9 2008) Explore Article

    Developing the client and server sides of a web app in two different languages is a well recognized problem. Many people would like to develop both sides in the same language. This allows developers to think in one language without needing to switch programming paradigm gears constantly (e.g. class-based to prototype/functional-based). Another goal is sharing code between the client and server. Form validation and something like a blog comment preview ... (Read Full Article)

  25. xjs, Synergy and YUICompressor together

    peter.michaux.ca (May 8 2008) Explore Article

    Last night I added the YUICompressor as an xjs module. This was trickier than I thought as the YUICompressor monkey patches the Rhino parser files. So I had to renamespace all the Rhino code and create a custom build of the YUICompressor jar so it can coexist with the normal Rhino jar. (Read Full Article)
