Re: Troubleshooting revIgniter library functions
Brilliant - thanks for the analysis and syntax corrections, Ralf. That’s clarified more of the LCS / MVC ‘plumbing' and provided a worked example I can repeat as I start to build-out the app proper.

Re: Troubleshooting revIgniter library functions
Hi Keith, seems that you have overlooked that your library handler is not a function, see line put somehandler() into gData["testlib"] in your controller. Furthermore don’t forget to adjust the name of your library initialisation handler to “rigRunInitialteslibConfig”. Ralf > On 30.

Re: Troubleshooting revIgniter library functions
Thanks Ralf. Renaming the library got past that library load error. However, the view page is listing other errors, which may hint at other mistakes I’ve made. The key page markup is below - I’d appreciate any advice. ** The testlib.lc library content is just the prototype with a “Hello World” test return in the example handler...

Re: Troubleshooting revIgniter library functions
Hi Keith, if you change the name of your library to Testlib.lc and if you adjust the name in your controller respectively all should work as expected. There is a naming convention for library files, i.e. camel case is not allowed, but it seems this is not mentioned in the user guide. Sorry for the hassle. Will fix that. Ralf > On 30.

Re: Troubleshooting revIgniter library functions
Thanks Ralf (& Andre) for the responses. I have read the user guide and understood more than I expected, given my basic HTML + jQuery + CSS background! I’ve also been learning more as I build my app out using user guide worked examples where they exist. Thanks for the syntax for processing the response returned from the library - I know understand the central role of the controller page and how that call & response should work. Thanks also for the tip regarding the log, as that has proven more revealing… errors when attempting to load library files into any controllers. Stripping back to basics, I have created a testLib.lc library file in the default system/application/libraries folder that contains just the prototype markup from the user guide. My default controller is home.lc (copied from welcome.lc) which throws an error "Unable to load the requested library:Testlib” if I add 'rigLoaderLoadLibrary “testLib” ‘ to the home or index handler markup. Any clues as to what I may have missed?

Re: Troubleshooting revIgniter library functions
Hi Keith, in addition to Andre’s valuable tips I would like to comment that your approach should actually work, but be advised to make sure you include your custom library as described here: https://revigniter.com/userGuide/general/creating_libraries.html Furthermore you can leave your function as is i.e. call your library function within your DocLogin.lc controller like: put myDocLoginHandler() into gData["doc_token"] For debugging purposes make sure the logs folder is writable, set the gConfig["logThreshold"] in config.lc to 4 and check the log file in case something goes wrong.

Re: Troubleshooting revIgniter library functions
Keith, RevIgniter is a normal LiveCode collection of libraries. Have you read the getting started guide at: https://revigniter.com/userGuide/overview/getting_started.html It will walk you through the concepts of MVC and how they are used in RevIgniter. Basically your models are the stuff that touch data, views are the templates that are shown to the user and controllers are where the business logic is. You can also have libraries. So if your DocLogin has a function that returns a token, you can call it from a model or a controller and get the value. There is really no "1 minute explanation" that will clear it all, RevIgniter is quite easy and consistent but it requires you to go over its documentation at least once. Some URLs of interest are: https://revigniter.com/userGuide/overview/appflow.html https://revigniter.com/userGuide/tutorials/chat.html I recommend doing the tutorial a lot.

Troubleshooting revIgniter library functions
Folks, I’m struggling to get my head around revIgniter / MVC concepts and map basic LC desktop concepts to the right places in LCS + revIgniter. (I’m still searching for a 'Rosetta Stone’ to translate between these two worlds!) My use case is to share public FAQs from specific pages designated as public in our knowledge base.
