Talk:Notecard Configuration Reader by Maddox Deluxe

Suggestions

Hello Maddox

You might find this code easier for validating a key:

<lsl> integer isKey(string test) {

  if ( (key) test)
      return TRUE;
  return FALSE;

} </lsl>

That's all you need to do. There's no need for the detailed inspection you have coded in your isKey() function.

You start your notecard reading by requesting the number of notecard lines - but you never use this information, in fact it appears that you will attempt to process the returned number of lines as if it were line #0 of the notecard itself, and you'll never process the true contents of line 0. In your application, I see no reason to request the number of lines. Just start by requesting a read of line #0.

Your IsElement() function is intended, I think, to ensure that a found texture name occurred at an index that was a multiple of 3. But it doesn't do so at all. Once the code passes the <lsl> if (~index) </lsl> test, it's bound to return TRUE.

Try this:-

<lsl> integer IsElement(list db, string search) {

   integer index = llListFindList(db, [search]);
   if  ( ! (index % 3 ) )

return TRUE; // was found on a stride boundary

   return FALSE; // was not found

} </lsl>

Your code <lsl>

   ++line;
   notecardQueryId = llGetNotecardLine(GetNoteName, line);

</lsl> would be better placed up where you have put the comment: // speed is the key when scripting, ... At present your code will stall on the first error encountered, as it will not go on to read the next notecard line, and will never reach EOF.

Why ask the user to code a full null key where no texture is desired? Why not look for a simpler specific string such as NONE?

I could go on, but that's enough ... except to say: do indent your code properly. You may find the offline tool lslEditor useful for this, as it has an auto-indent feature.

Well Omei, there is many ways to code things and everyone has their own style, but this script works just how it was made to. It has been tested many ways for error checking with the notecard format. I made it from on going project of my, the demo script just shows how you could handle themes UUID keys and using list for them. The "Error Checking" is 100% good.

All you got to do is run the test scripts and you will see they work fine. The format notecard was not made to handle spaces, the comment lines works just fine as long you keep each line right under each other.

This will work.

It does not handle spaces over the error checking, I had change the codes, but it did handle spaces at first. I will work the spaces part out and fix it later. I do know I should had not rush and try to share the script so fast, I'm bad at that and should had did more testing before hand. v1.3 not bad, just can't use spaces right now. I been out of second life for a long time, but I'm sure the scripting has change a lot over the months. The functions still does the job and seem to work very fast. Thanks for showing other ways to check things, from now on I will make sure the script is 100% done before sending it to the wiki.

Thanks Maddox. You might like to try these bad keys, all of which will sail through your isKey() as valid, but all would be rejected by the much easier, shorter and FASTER if (MyKey) ... process.

<lsl> "8f3O4cf2-7120-24e2-d1f1-db6b31bd6f6c" "8f304cf2-7120-24e2-dlf1-db6b31bd6f6c" "8f304cf2-7120-24e2-d1f1-db6b31-bd6f6" </lsl>

The first has a letter O instead of 0 (4th character), the 2nd has a letter L instead of a 1 (2nd character in 4th group), and the last has an extra hyphen instead of a hex digit. Omei Qunhua 01:39, 26 April 2014 (PDT)

Thanks Qunhua, I will check things out soon. I need to get my butt to bed right now, thanks for update info.... Here I made a video for you to check out, showing the project with the script.

Here is the video:Click Here to watch

Sorry to say there's still big problems. You might like to consider why your test returns a uuid starting with "8f30..." for Fantasy Car Backdrop Texture, when the correct UUID starts with "517b...". The reason is based on the fact that for every non-comment line in your notecard, you add 3 entries to your Themes list. So when you read the line [Fantasy Tiger] you add the string "Fantasy Tiger", AND two (default) null keys to Themes. Then when you read the line with [BACKDROP TEXTURE UUID] you add a further 3 entries, "Fantasy Tiger", the Backdrop UUID itself, and a Null key. Then when you read the [Floordrop Texture UUID] line, you add a FURTHER 3 entries: "Fantasy Tiger" again, the Backdrop UUID again, and the new Floordrop UUID. This process is repeated for every line of the notecard. So your lookup process is going to be a disaster. When you reach the "Fantasy Car" line, you add "Fantasy Car" to Themes, but you also add the old keys from Fantasy Tiger. Corrected entries follow on later in the database, but this is too late; your search will find the first (invalid) entry. Omei Qunhua 04:34, 26 April 2014 (PDT)

That is what second life copy asset UUID gave the images. 

Fantasy Tiger:8f304cf2-7120-24e2-d1f1-db6b31bd6f6c 
Fantasy Car:517b2288-67ca-b14c-1de2-c5f5fdf5291f 
Fantasy Tree:f6321118-cc24-6230-78a5-a257a3e33378

It all works and finds the tetxures and button names.

But in the test script it not 100% the same how the studio works, I will look into it and see. The strings for the search are return from the menu buttons linkmessage event, cause of the menu system that part does not work the same, but the codes should had work still. I am checking it now and will see what is up with it.

I see what is wrong, for some reason the test script is no longer setting the themes list format right. Damn, one thing after the other but in the studio the format is ok.

Crazy lol.. anyway I will work on it for a bit.

BTW,, if you REALLY want to check that 4 consecutive characters are Hex, I'm pretty sure this would work:-

<lsl>

           string char = llGetSubString(check, i, i+3 );    // (from your existing isKey() function)
           if ( (integer) ( "0x1" + char ) < 65536)
               return FALSE;
           ... etc.

</lsl>

At least it'll be better than your existing test which fails miserably. Omei Qunhua 14:59, 26 April 2014 (PDT)
