Re: LiveNode Server
Thanks for this Andrew - I learned a lot. I spend a lot of time passing messages around Livecode objects with a view to making them standalone code chunks. Debugging works pretty well - but there was a need for a library and a graphing mechanism - design pattern style. This all adds overhead I guess when it comes to just reading code, and the design patterns for callbacks that closures seem to encourage makes this easier by itself? One thing that would be good to know more about with regard to Livecode is the memory handling - so when does a peice of code get released from memory? My understanding is that it does not - except possibly when the stack it resides in is deleted from memory? Otherwise my understanding is that like with Hypercard the script is compiled to bytecode the first time it is executed (which is a relatively slow step), but thereafter resides in memory to be executed when needed. Is that about right? It makes me think of an architecture in Livecode using [[dispatch]] where a stack is loaded that contains the needed code should the dispatch call not be handled by the message hierarchy - by default this stack could be deleted after it is called - so releasing it from memory. Commonly called handlers could be loaded before hand by a different command and therfore stay in memory. On 7 April 2015 at 21:21, Andrew Kluthe and...@ctech.me wrote: 1.

To the point where I ended up completely redoing most of the livecode stuff I've written in this way early on because it was getting to be a nightmare to maintain a completely separate callback functions rather than the sort of nested structure you get in node with callbacks. It takes a lot of discipline in placement and grouping of the code that is related in this way to come back later and make sense of it. In summary: it can be done, but that doesn't mean that it SHOULD be done. Kind of a weird long post there. Sorry for the length and probable repetition of my points.

Re: LiveNode Server
Yes I second that - async file and network I/O. And full REST support - PATCH I think is not supported - or is that documented? On 7 April 2015 at 23:44, Andrew Kluthe and...@ctech.me wrote: I'm not using LC server side much so I can't say for sure there in reference to this thread and the things we've been discussing. I think the direction livecode is going and the state that it is/was (I still use 5.5 for a lot of things) in to be great. If we can get as many of the blocking bits down to a minimum as possible (specifically the url libraries), I think it would be perfect. The thing that peeved me most is that most of my DB work is not done by directly connecting to the database but some sort of api layer. Usually my LC apps are just clients for these apis (often built in Node or python if they were made in-house). I like the flexibility this gives me. They post some JSON and get a JSON payload back. If the payload is large, I've had to do things like use curl and some other things to make up for the built-in super convenient internet library just sitting locking the application while it waits to return. I've converted entire applications out of LC into other technology stacks just because of the kludge needed for this one thing. I'd love to be able to stream this stuff in a little bit at a time as well. I can get some desired results with regular GET request using load url with a callback but it doesn't help when I have to post a more complex query. This happens in my .NET apps as well, but I use the parallel task libraries .NET has to get around the UI lockups. I've been spoiled on some of visual studio's tooling features in the meantime too :P (intellisense, jump to definitions, some other things that i think will come to LC in time). I also have a node-webkit (now nw.js) application that I think would be perfectly suited to be done in livecode once things stabilize a bit (this has already started to happen) with the newer builds using Chrome Embedded Framework. I needed something with all the fine tuned styling I could get from web app we already have but running as a standalone against SQLite DB. We did this to reuse the same visual cues and javascript libraries that we use on the web version. We wanted a copy of the web application that could run completely without the internet. I think with just a bit of time, I could have used LC to do this comfortably. The short answer? An url library that can read a file off disk asynchronously (I think this can be done now using some of the other ways of doing disk access in LC, but it would be nice if the url(binfile:) bit did the same thing) and an url library that can return the response of a POST asynchronously (preferably returning chunks as they come in). The widgets architecture sets itself up to solve all of my other potential wants/needs, maybe even this one.

When is a stack dirty?
After several years of using Livecode, I still don't understand how the IDE decides when a stack needs to be saved when I quit from it. As an example, if I delete a substack by script then quit, the stack isn't saved. If I change the vale of a custom property by script then quit, the stack isn't saved. Same thing happens if I add a new substack by script. And if I change the value of a custom property by script. Surely the IDE should be aware that a save is needed in those circumstances?

Re: [OT] Market Share
Kay C Lan wrote: It's normally Richard who comes out with the OS Market Share figures and I must admit I normally sort of switch off at that point because I've sorta heard it all before - OS X is an ever so small number. I mean, some of us like chocolate and others strawberry and no amount of statistics is going to make that change. I use what I like, you use what suits you. Agreed. To clarify, I usually bring up OS stats only in response to the perennial Why doesn't LiveCode support Amiga/BeOS/someOtherDefunctSystem? stuff that comes up from time to time. Like most Linux users I know, though I may prefer it myself I'm not nearly as evangelical about such things as I used to be when I used Macs exclusively. After all, one of the great things about LiveCode is that it liberates us from the whims of any single OS vendor, so everyone can develop on whatever they prefer and still deploy to all. So while market share stats should rightfully have zero impact on anyone's personal choices, they're useful for developers in assessing potential ROI. But even then their value is limited. No matter how you slice it, the desktop is always a Windows story, with both OS X and Linux relative niches. And there's more to the story than a single data point of market share: OS X tends to attract an audience of higher-than-average disposable income, and Linux tends to attract an audience of code contributors, so each offers something uniquely valuable beyond market share alone. For reasons I can't explain I always thought that amongst 'real programmers' the statistics would be even worse, Windows the majority, Linux steamrollering ahead, and OS X a very distant and poor cousin. So I found these figures... well unbelievable: http://stackoverflow.com/research/developer-survey-2015#tech-os Developer-centric stats like those may be especially interesting to those who make developer tools. That's a good find - I haven't come across it before, usually looking to w3schools for dev stats: http://www.w3schools.com/browsers/browsers_os.asp The w3schools stats are very different in specifics, but not all that different in terms of the overall story of Windows dominance with Mac and Linux playing minor roles: 2015 Win8 Win7 Vista NT* WinXP Linux Mac Mobile February 21.3% 52.5% 0.8% 0.4% 4.5% 5.4% 10.0% 5.0% There the Mac share is roughly proportionate to total market share, while the Linux share is much higher than the frequently-cited 1%, a healthy reminder that reliable Linux stats are unusually hard to come by given the mix of usage patterns coupled with the way log aggregation sites that come up with the mythic 1% figure admittedly alter their data. But either way, Linux isn't taking over the desktop any time soon, and neither is Mac. But thankfully none of that affects our own personal preferences, and all three are good viable choices for working with LiveCode. -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ambassa...@fourthworld.comhttp://www.FourthWorld.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: LiveNode Server
To clarify just a little bit further. The code and objects weren't holding onto memory, the variables used in that code were due to weird scoping. Big chunks of db results, etc that persist after I've already done my business with them and tried to move on. If I can recommend a book on Javascript, I can't speak highly enough of the insights given by JavsScript: the Good Parts from O'Reilly. He provides some history behind some of the design choices in javascript and some of the problems still being worked around today in regards to the bad parts.

Re: hide / show oddities ?
There were some posts on this list about 4 months ago re: hide/show objects strangeness (http://runtime-revolution.278305.n4.nabble.com/hide-show-oddities-td4686263.html). Having struck this today on a project I’ve come to the conclusion that it’s something to do with the graphics caching that is being used when we have acceleratedRendering set to true. In our case, we had some scrolling groups with subgroups in which each contained buttons that may be shown or hidden at times. It appeared as though these weren’t being updated, however, if the overall containing group wasn’t visible. Once it was made visible however, scrolling the group would update all the child objects ok. However, that’s not good enough… So the solution for now, on entry to this card, is to turn acceleratedRendering off, which presumably disables the graphics caching, and all objects are now updated correctly. Yet to be seen is the effect this may have on other bits that perhaps need the better graphics performance… So if you’re also seeing strange behaviour with hide/show or setting the visible property, try turning off acceleratedRendering to see if that helps. (I’d already tried setting the layerMode and it didn’t seem to help).

Re: Current Player Bugs in LC 7
Thanks, Tom. This explanation makes sense—the fixes are being rolled into LC 8, rather than 7. However this leaves 7 with a broken player.

[OT] Market Share
It's normally Richard who comes out with the OS Market Share figures and I must admit I normally sort of switch off at that point because I've sorta heard it all before - OS X is an ever so small number. I mean, some of us like chocolate and others strawberry and no amount of statistics is going to make that change. I use what I like, you use what suits you. For reasons I can't explain I always thought that amongst 'real programmers' the statistics would be even worse, Windows the majority, Linux steamrollering ahead, and OS X a very distant and poor cousin. So I found these figures... well unbelievable: http://stackoverflow.com/research/developer-survey-2015#tech-os Then again you can use statistics to argue anything. Maybe these numbers suggest that there's just a lot of confused programmers seeking answers on OS X ;-) ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Database error?
I’m profoundly ignorant of databases in general and the way LC talks to MySQL databases in particular. Gregg Flora gave me a script for a handler which communicates with a mySQL database I thought I’d created using the On-Rev cPanel: but when I query it by running the script I get this error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) I am 99 percent certain that I have the name of the host, the database itself and the user all correct, plus the correct password for that user. Perhaps the creation process didn’t really created the database (although the cPanel display says it did). Can anyone suggest what I should do next?

Re: When is a stack dirty?
Hi Pete, The variable gRevStackStatus[Short name of a stack] is set to true whenever a control moves or changes as the result of user input. Messages triggering an update or gRevStackStatus are openField and focusIn for example. I think that moveControl and resizeControl are monitored too. I haven't checked which messages are monitored, for a long time. Whenever you bring a stack with a field to the front, the IDE finds the first field that has the lockText set to false and the traversalOn set to true. This field gets focus and gRevStackStatus is set to edited. Whenever you try to close a stack, or quit the IDE, LiveCode briefly sets the focus to each of the stacks that is currently visible. The first field gets the focus and thus the gRevStackStatus is set to true --if it has a field. In other words, the IDE sets gRevStackStatus to true for any stack with a field, before you close it, and you will always see a Save dialog for these stacks. If you want to prevent this from happening, you will need to write your own frontscript that handles the closeStackRequest, shutDownRequest and appleEvent messages. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering Homepage: http://economy-x-talk.com Twitter: http://twitter.com/xtalkprogrammer KvK: 50277553 Installer Maker for LiveCode: http://qery.us/468 Buy my new book Programming LiveCode for the Real Beginner http://qery.us/3fi LiveCode on Facebook: https://www.facebook.com/groups/runrev/ On 4/8/2015 18:33, Peter Haworth wrote: After several years of using Livecode, I still don't understand how the IDE decides when a stack needs to be saved when I quit from it.

Re: Database error?
Let me add this too. In Cpanel when you create a database, you're asked to 1) create a database, 2) create a username and password for that database, and 3) assign a username to that database. This isn't necessarily the same as your Cpanel login, but can be if that's how you create your database. And as I mentioned previously, when connecting to MySQL it's username_database then your password. Of course you need your domain info. -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/Database-error-tp4690936p4690948.html Sent from the Revolution - User mailing list archive at Nabble.com. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

if the filename property is empty, store the text of the image to a property or variable, pop in your new image, then to revert, set the text of image whatever to the text you stored in the property.

Re: When is a stack dirty?
Thanks for the info Mark. That probably explains what is happening in my case because the substack I delete is not open at the time I delete it. What I'm thinking of doing is setting the gRevStackStatus element for the main stack of the deleted substack in my script which sounds like it should result in the IDE issuing a save prompt when I quit. I will probably have to do the same thing when, for example, I change the value of a custom property in an unopened stack.

As an example, if I delete a substack by script then quit, the stack isn't saved. If I change the vale of a custom property by script then quit, the stack isn't saved. Same thing happens if I add a new substack by script. And if I change the value of a custom property by script. Surely the IDE should be aware that a save is needed in those circumstances?
