What do I need to do to get a Data Grid form to scroll when dragging a row that you'd like to drop in a row that is not in view? Data Grid tables just work as far as I can tell. When the mouse hits the top/bottom of the data grid while dragging, the DG will scroll. Data Grid forms do not. The quick ...

I'm wrestling with a strange behavior on my first App using sockets. In a nut shell, I'm writing what I think is a simple client/server app for a round-robin Tournament. I a nut shell, there is a Head judge system (server) receiving results and scoring information from up to 6 arenas (clients). Each...

I have an LC project where I need to select a random number from a weighted array of numbers. The weighting is essentially a bias on randomly selected the element. I've written a routine that I think is an efficient solution to this problem. I'd love feedback/advice on how to make it faster as I am ...

WOW! Looks like I will be moving to 8.0 ASAP for a couple of my projects that are in development. That's really impressive!

Ah, thanks for clearing that up. Now it makes sense. I was having a senior moment I guess...

Today's issue of This Week In Livecode (TWILC) pointed to an interesting bug report that got my attention. I've started a project to bring HMVC to revIgniter which relies on ".." to walk directories. My project is based on 2 Codeigniter HMVC projects that use ".." to walk the servers directories to ...

I'll start creating versions to make it easier. Thanks for the tip. The solution is really easy to the performance issue. I simply made a case in the parsing switch statement looking for "" and simply returning it. I have no idea what's happening but I don't think it's a bug in Livecode. I'm suspect...

Just created branch 4.0.1. Includes fix to pText, declaration of local vars for strict compilation, and most importantly, THE FIX TO "RUNS FAST ONCE THEN NOT" :D Here's what caused the issue. If the JSON data contained a data pair of "name":"", Livecode would forever run the library slow. I added in...

I've noticed in my testing a strange behavior and am wondering if someone might be able to steer me in a direction to track down the issue. When I use my test stack on the dictionary here's what I've noticed. Launch LC 7. Launch test stack open Livecode Dictionary json file and run tests. Speed is V...

Pete, user error. I did a copy/paste in ATOM and must of double pasted the dictionary file. Thank goodness! I've attached a screen capture of my test stack's results of parsing the dictionary (old and tired 2007 iMac). 405707 tokens got parsed in 18.5 seconds and 12.9 seconds to go back to an array....

HMM... let me look into it. I have no idea what's up with that. I am on Mac OS 10.10.5 and I'm using LC 7.1 Indy but did get the Dictionary JSON from LC8 DP6 Community. I have a bouncy icon yelling at me to upgrade my LC which I will do momentarily and see what's in there for a dictionary. Pete, THA...

Been working on this today. The issue is that the data is not valid JSON. a) I need better error handling in the code. isJson() determines that the JSON is not valid. b) confirmed the json is not valid by running it through a known json linter. fastJson isJson() determines that the {[]} are off by 1...

Well, hold on... while it looks like the library did parse the file and my initial look at the data I thought was fine but I think there's an issue. I'm going need to do some more detailed analysis before I make my final conclusion that we have a valid array in LC.

I was able to find the LC Dictionary file in LC8. I'm also happy to report that the 0.3.1 branch of fastJson was able to convert the JSON to an array and back again! Converting the 9.8MB JSON file to an array took about 24 seconds on my 2007 iMac. This is by far the largest JSON file I've run throug...

I'm committing changes to the 0.3.1 branch in Git. If you right click the fastJson.lc link and download to a file, this is the most recent version of the development branch. These changes are not in the "master" as of yet. You can also click the link then copy/paste the code into your Library stack ...
