Re: Speaking of Filter and Match...

[Terry Judd via use-livecode]

There are sure to be more elegant ways but you could just rebuild the list 
skipping the duplicates as you go

# tList1 contains original list
put cr into tList2
repeat for each line x in tList1
if tList2 contains cr&x&cr then # ensures you check whole not partial lines
# do nothing
   else
put x&cr after tList2
end if
end repeat
put char 2 to -2 of tList2 into tList2 # delete the leading and trailing returns

If you need to retain line specific formatting in the field though you’ll need 
a different approach.

Exactly. You want matchtext, not filter.

There is a way to finesse this if you really need to use filter:

   local tSubString, tTarget, tLargeTextString
   local tResult

   put "*THIS*FIND*" into tTarget
   put "abcdef&cr&ghijkTHISISMYTEXTTOFINDlmnopq&cr&rstuvwxyz" into 
tLargeTextString


   filter tLargeTextString with tTarget
   set the itemDelimiter to "THIS"
   put item 2 of tLargeTextString into tSubString
   set the itemDelimiter to "FIND"
   put item 1 of tSubString into tResult

Your source was only one line.  The default for filter is to work by line.  It 
returns all lines that match, hence the same string you started with.

put "THIS*FIND" into tTarget

put “abcdefghijkTHISISMYTEXTTOFINDlmnopqrstuvwxyz” into tLargeTextString

put tLargeTextString into pText


— Adding your code here Mark:
put ".*THIS.*FIND.*" into tTarget

filter pText with regex pattern tTarget into tFilteredTextResult

answer "tFilteredTextResult = " & tFilteredTextResult

yields: 

tFilteredTextResult = "abcdefghijkTHISISMYTEXTTOFINDlmnopqrstuvwxyz”

So what did it filter?  It’s the same string I started with.

Re: LC Player buffering data

[J. Landman Gay via use-livecode]

Someone who does a lot of audio work would know more than I do about it, but it used to be that 
files could be saved in either "normal" mode or "streaming" mode. I didn't make the files I 
used in a particular app, but they all streamed and playback started immediately while the rest 
loaded in the background. If things haven't changed, maybe the file format is the culprit?


On 3/12/22 12:35 AM, Peter Bogdanoff via use-livecode wrote:

I should have said, the audio files being played are typically 30MB to 100MB, 
and the freezing happens as soon as the filename URL is set and play is 
supposed to begin.

Hi, this is probably a question for Panos.

My application plays audio files from a server using the player. Some users in 
a academic environment are experiencing the application freezing when they play 
audio. These are people in a university in China, where it seems the wireless 
network gets choked up with simultaneous users doing things. When classes are 
over, all works well. Also using a cellular connection works normally (but data 
there is very expensive $$$ to use). Their Wifi seems to be underpowered. These 
are files typically 30K to 100K.

1. Does the player buffer data such that it allows the playing to start before 
the entire file is loaded?

2. If so, would reducing the minimum amount of buffering help with this issue?

3. If so, could there be a player setting to set the amount of required data 
before playing begins?

Thanks!

Unless you use "filter x without y".

Re: Speed up a slow loop

[J. Landman Gay via use-livecode]

I have to thank everyone who helped me figure out my Boggle game. I've put the current file on 
Google Drive for anyone who wants to take a look. The scripts are open and I think I've removed 
all the testing cruft that accumulated over the last couple of weeks.


I'd be interested in any feedback or improvements. There's a Read Me in the zip file with more 
info.




Thanks so much to all! Contributors have been credited in the scripts.

Yes. It does. Filter won't give you a substring.

You can use filter to get the whole line of text, but you'll still have 
to dig out the substring if that's what you're after.


In your original code, change to
put "*THIS*FIND*" into tTarget
filter pText with tTarget into tFilteredTextResult
or
put ".*THIS.*FIND.*" into tTarget
filter pText with regex pattern tTarget into tFilteredTextResult

Good Morning!

I’m trying to get filter to work with some text and so far no success at all.

Given large string:  abcdefghijkTHISISMYTEXTTOFINDlmnopqrstuvwxyz

I want the text between THIS and FIND which could be anything like ISLJFKKDKLS

It’s OK to include the THIS and FIND in my result.

I’m thinking I need a wildcard character like * to get the information.


So if I try:
put "THIS*FIND" into tTarget

put “abcdefghijkTHISISMYTEXTTOFINDlmnopqrstuvwxyz” into tLargeTextString

put tLargeTextString into pText

filter pText with regex tTarget into tFilteredTextResult

answer "tFilteredTextResult = " & tFilteredTextResult

One might think this would work, but it doesn’t, and I get nothing for 
tFilteredTextResult

Suggestions?


Try matchtext rather than filter:

local tTextt, tFound?
put matchtext(tLargeTextString, ".*THIS(.*)FIND.*", tText) into tFound?

Re: LC Player buffering data

[panagiotis m via use-livecode]

Hello Peter,

Off the top of my head, I think there is a related read-only property
("loadState") but this is for the iOS mobile player. So you can get the
value of this property using the mobileControlGet command, and start the
video playback accordingly. However, if I remember correctly, your app runs
on Mac and Windows. is that correct?

I suggest you file an enhancement request, my guess is that it shouldn't be
too tricky to add such a property, at least for the Mac player.

Cheers,
Panos
