Thank you for sharing the code.

I don't like to use \"use resource\" because it loads  everything even though some javascript is not needed in a certain context. \nFor now kynetx apps are relatively small of size but I think in the future they could become more complex and that's when we will need to load the js just when needed. \nActually I don't just include js libraries like jquery plugins that don't change during development. To keep a ruleset light I chose to\ninclude one js file in every \"emit\" par of a rule . When I do that I can work inside my eclipse IDE editing  the js file of the rule I am working on and I don't add code in the appbuilder. I can version the js file in a repository (svn). In other words the app becomes a lot more modular and easier to read in my opinion. But \"use resource\" is a static string so I can't cacheburst the js files and I don't  trust the browsers or KRL to retrieve the last updated js file .\nWith this technique things become more dynamic and as a consequence more flexible. I can cacheburst, I can easily change the location of the files. When I finish debugging an app I generate google closure compiled js files with an ant script, upload the files to an online server  and change the flag dev=true to dev=false in my ruleset and the app will use the online compiled js files. No hassle.\nIn a previous technique I included script tags dynamically with src attribute, this was even better because I could host my js files on a localhost apache and that speeded the development.\n", "group_id": 236, "id": 952291}, {"user_id": 30494, "stars": [], "topic_id": 34095, "date_created": 1304795556.6091609, "message": "The problem was that it increased complexity because there is no reliable cross browser mechanism to know when a script is loaded so I had to use setTimeouts to check if a function was available before actually using it.\nI might switch back to this mechanism if I find a cleaner way to handle the timeline of code execution.\nWith these techniques I managed to run some of my apps locally , in offline mode, testing on my local apache. This is very convenient for development and was a necesity because where I live bandwith is not always the best.\nThat's what makes me think that we could figure out a way to push some apps on Mozilla addons. \nI hope I am making myself more or less clear. \nI intend to publish some kind of \"ruleset code template\" to illustrate that once I'll be really satisfied with the tools I use. The main goal of this template is really to have :  reusability/readability of code and allow a team to work on a same kynetx app which in my opinion means \nbeing able to have a local testing environment and versioning of source code.\n", "group_id": 236, "id": 952293}, {"user_id": 4291, "stars": [], "topic_id": 34095, "date_created": 1304797984.03421, "message": "@loic Thank you for the detailed explaination!
