I ran into this when doing mobile predictive typing for US cities(40,000) with a scrollable dropdown of results. I did with a loop in JavaScript in html and was instantly fast. So in LC IDE I started with the loop thing and it was too slow. There was a 3/4 of a second blip as each character was typed. I found that "filter the lines" is blazingly fast. So I built the cr list of cities with the city followed by a dash and then the metadata I needed (lat/lons). Use the "filter into" form so the original list remains unchanged. I do a filter for each character typed. Works like a charm. Now LC is as fast as the JavaScript version. When filtering if you want the exact term then search with the dash added at the end for the search term.
"filter" must be using your time machine somehow.

Landman Gay Subject: Speed up a slow loop In my Boggle game I have an array containing dictionary words as keys, split as set, so all values are "true". I need to compare those keys with a list of user words and get back a list of good words and a list of illegal words. The loop takes forever. Here it is (sDictFile is a script local): repeat for each line l in pList -- pList is the user word list if sDictFile[l] = true then put l & cr after tCheckedList else put l & cr after tNonWords wait 0 with messages -- prevent ANRs end repeat I added the wait because my Android phone was putting up an "app not responding" warning while the loop was running (or just after, hard to tell.) The loop should be much faster than that. When I added some timing checks though, the timer says the loop takes between 0 and 1 millisecond, and yet the wait on screen remains. With a 3-word user list, the loop takes 4 seconds. With an 8 word user list the loop takes 6 seconds. The more user words, the longer the wait. Even stranger: on my cheapo Android tablet with 4 megs of RAM running Android 9 the response is nearly instantaneous, even if the user list has 200+ words. On my Pixel phone with 8 megs of RAM and Android 12 the response is slow enough to trigger the ANR with only 3 words. I'm building for ARM 64. I've tried any number of workarounds without luck, on both LC 9.6.6 and LC 10.0.0. Any ideas? I have a feeling it isn't the script per se, it's something else. -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.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 _______________________________________________ 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
