Pete Olihenge: /* check if a string contains valid integers */

Are these numbers correct? "values between −2,147,483,648 and +2,147,483,647" . And if they are why the difference between the figures? -- '''[[User:EddyFragment Robonaught|Eddy]]''' ([[User talk:EddyFragment_Robonaught|talk]]|[[Special:Contributions/EddyFragment_Robonaught|contribs]]) 17:30, 27 June 2009 (UTC)

:Aye correct as saved.

:This truth makes more visual sense in hex. A 32-bit two's complement integer is 0x0, or +0x1 thru +0x7FFFffff, or -1 thru -0x7FFFffff, or -0x80000000. In decimal, that is 0, or 1 thru 2147483647, or -1 thru -2147483647, or -2147483648. The assymetry comes from the zero: both positive integers and zero have the uppermost most bit of the 32 bits zeroed, so the list of positive values loses one element to make room for zero.

:A correspondingly counterintuitive result here is that negating -2147483648 has no effect (-2147483648 == ( 0 - -2147483648 ) == ( 2147483647 + 1 ) ). Ugly as all this is, it's less ugly than the known alternatives, such as the one's complement encoding that can have two zeroes: a positive zero and a negative zero. All that I'm saying here is the convention I remember learning years ago, I imagine LSL behaves this way at these limits, but I haven't tried to see yet ... -- [[User:Ppaatt Lynagh|Ppaatt Lynagh]] 18:10, 27 June 2009 (UTC)

::Thanx Ppaatt. I thought it might be a zero issue but didn't get as far as thinking that (of course) there would have to be (as you say) two zeros for the reach (both pos and neg) to be equal. "Positive Zero". Sounds like a good title for a science fiction novel.

::In addition to (--2147483648 == -2147483648) so does (-1 * -2147483648). Everyone knows that 1/0 causes a fatal error in integer math but what few people know is that (-2147483648 / -1) does as well on x86 processors (modulo is equally affected). I have yet to find any mention of this on the internet (except where I have posted it), I found it by accident while exploring edge cases (it crashed the sim). In LSL we papered over the exception, any time you divide by -1 we just apply the "-" operator, and for modulo -1 we just return 0. -- '''[[User:Strife_Onizuka|Strife]]''' ([[User talk:Strife_Onizuka|talk]]|[[Special:Contributions/Strife_Onizuka|contribs]]) 09:27, 29 June 2009 (UTC)

== Sub-classification Constants/Functions ==

I thought I'd take a quick peek at possible Integer-related Functions.
A sea of Constants greeted me. Is a Sub classification perhaps useful? --[[User:Vernes Veranes|Vernes]] 00:43, 8 January 2010 (UTC)

: [[LSL_101/LSL_in_Focus:_Integers|LSL in Focus: Integers]] classifies how integers are used in LSL, and might be what you are looking for. The uses are: signed integers, truth values, enumerations and bit vectors. I think every LSL integer constant clearly falls in exactly one of these four categories.--[[User:Omei Turnbull|Omei Turnbull]] 03:28, 8 January 2010 (UTC)

The first sentence on this page reads "An integer data types are signed 32 bit values [...]"; I think this should read "The integer data type is a signed 32 bit value [...]".

== check if a string contains valid integers ==

The category tab shows a function to determine whether a string of characters consists only of integers.
The following would also check that, but I've never yet added anything to this wiki, so added this here for comments

if ((string)((integer)(input)) == input)
{
llSay(0, "The input contains only valid integers");
}
[[User:Avi Savira|Avi Savira]] 17:06, 30 October 2011 (PDT)

:Both methods fail on a signed positive integer ("+1234"), but this seems to be way more efficient. If you do put it into the main page, it'd probably be best to do so as a function. [[User:Pete Olihenge|Pete Olihenge]] 08:30, 1 November 2011 (PDT)

***This is not limited to listens and permissions but anything that caches the return value, it is up to the programmer to work around this limitation.
**Detection of owner change can be achieved with the [[changed]] event in conjunction with the [[CHANGED_OWNER]] flag (see the second example) or by storing the old value and periodically (e.g. in [[on_rez]]) checking if it has changed. Both techniques are valid though the latter will not detect the sale of the object if it is sold with "sell original" in-world and not picked up.

To retrieve the owners name while the owner is in the region use [[llKey2Name]], [[llRequestAgentData]] should be used when the owner is not in the region.

The one problem many coders come up against is that previously-activated events referring to the owner don't automatically change when the owner changes. The most often-seen result is a listen registered to owner will continue to listen to the PREVIOUS owner rather than the CURRENT owner. It is often confused as a bug in [[llGetOwner]] or [[llListen]] it is not in fact a bug but part of the design. There are several ways of working around this problem. The easy solution is to reset the script when owner changes or it is rezzed. The easy solution is not always the right solution.

There are two ways to detect if the owner has changed, the most reliable is to use the [[changed]] event.
<lsl>changed(integer change)
{
if (change & CHANGED_OWNER)//if owner changes, reset the script.
llResetScript();
}</lsl>

In many applications resetting the script when the object is rezzed is an adequate and easy solution.
<lsl>on_rez(integer start_param)
{ //when the object is rezzed, reset the script.
llResetScript();
}</lsl>

Resetting the script is not appropriate if the script needs to keep it's data when it's ownership is transfered or if script startup is slow, in these situations listens will need to be re-keyed to the new owner along with any other owner specific code, like who the script is supposed to be animating.

The [[on_rez]] and [[changed]] events can be harnessed to reinitialize owner specific code every time the object is rezzed or changes owner.

<lsl>integer listen_handle;

init()
{
key owner = llGetOwner();
llListenRemove(listen_handle);
listen_handle = llListen(0, "", owner, "");
llRequestPermissions(owner, PERMISSION_TRIGGER_ANIMATION);
}

default
{
state_entry()
{
init();
//insert additional startup code here that doesn't need to run each rez/owner change
//for example, reading settings from a notecard
}

on_rez(integer start)
{
init();
}

changed(integer change)
{
if (change & CHANGED_OWNER)
init();
}

run_time_permissions(integer perm)
{//always use the run_time_permissions event with llRequestPermissions, never assume
if(perm & PERMISSION_TRIGGER_ANIMATION)
{
//setup your animation code here, start your timers, etc.
llOwnerSay("I have animation permissions");
}
}

=== Re: Formatting [topic added by Void due to page reordering] ===
{{message}}It looks well thought out. I'm pretty laid back about style as long as it's consistent. The only thing I put my foot down on is tabs being 4 spaces. All a matter of preference thou. I find prefixing variables with anything other then a letter to indicate type is overkill. I write my LSL as ESL (which is LSL passed through a C precompiler) and I reserve all uppercase lettered names for ESL macro's and defines. -- [[User:Strife Onizuka|Strife Onizuka]] 03:09, 3 November 2007 (PDT)
 
{{message}}Amazing. I've been programming for 25 years and have developed a style that chooses the opposite of most of Void's rules. Why is it that these questions lead to such equally satisfactory results in competent programming organizations that are so different. I suppose that it's similar to the reason that Spanish isn't the same as French.
I'll go Strife one further, though, and put my particular foot down about the insane (to me) verbosity of prefixing variables, function names, etc. with garbage characters that serve no useful purpose I can see, and is constantly bonking the reader who has to read through several largely irrelevant or self-evident characters to get to the important part - what the variable is. It's like getting tapped on the side of the head with a pencil every time I trip over one of the darn things. Is this another sad legacy of Microsoft? I'd never seen such a thing before I had to start writing Windows code. And I'll note, I work in RL in an environment where we have several hundred thousand lines of legacy code I have to refer to regularly, (and a couple of legacy programmers) that use "Hungarian" notation like this, and after 10 years of reading it I STILL get tapped every time I see one.
I do have one possibly pertinent point, though. I had been ambivalent about where the brace at the opening of a block goes for a couple years, having programmed in environments for most of my time where they were to be on a (wasteful) line of their own. After spending some time in Java, where the convention tends to be 'on the same line' I was still uncertain I had an opinion, except that I really don't like the effect that mixing the styles has. (That happens with templates, copy/paste, etc.) However, a few weeks ago when working on some poor code (mine) that was too long and nested too deeply I spent quite a while tracking down a missing opening brace. I realized that had it been on its own line I'd have seen it almost immediately. Given modern monitor resolutions and sizes, I don't think the vertical height saved is worth the obviousness that it exists.
So there, finally the definitive answer to the "same line or different line" question.
Ah, the style wars, long shall they rage.
 In the end, as both you and Strife observe, it is all personal preference as modified by the need to be consistent with those you work with. Thanks, much, for taking the time to write it down. I should do it too if I care so much I guess. --[[User:RJ Thibaud|RJ Thibaud]] 12:25, 23 December 2007 (PST)

=== RE: style etc ===
{{message}} heh, thanks for reading it at least, I'm not fanatical about it, each person develops their own style, and to be honest I only adapted the style I normally use for lsl, from my other coding projects, so it's prone to updates (a few of which I've yet to add in). The particular style I use is geared towards maximum understanding of the code for those new to scripting/programming so they can more easily find their way through code. But as noted, for an experienced coder it can be a bit like 'duh I know that'. Coming from an enviroment with lots of new coders though, I tend to keep it up for their benefit more than my own. The opening brace debate is long running with me, and I do realize the pro's and cons, but have gotten myself in the habit of expecting open braces on the same line, and visually reading the statement (if, do, etc) and the indent as opening the statement and even briefly played with inlining the closing statement (but found it interfered with the visual nesting effect sometimes).

I mostly provided the example style as something to explain, rather than recommend, because I was bored enough to write it one day, and had been asked a few times about it. I have found that prefixing of some kind tends to avoid collisions with developing languages like lsl, as I noticed happened once or twice when people named constants or variables that later became LSL constants, and I've discouraged a few people from using llFunctionName for that and other reasons (like people that see the call and try to use it elsewhere). I'ts all good though, whatever gets the job done and works as expected. [[User:Void Singer|Void Singer]] 13:35, 25 December 2007 (PST)

== 0x80000000 X_X ==

Yep I forgot about 0x80000000. The limit however accepts 2038 and then overflows. So I wrote a version that detects overflows and accepts the entire integer range. It should be noted that if you get clever on it, and give it a year before 1970 but have the final date fall in or after 1970 it will have a fit. Likewise for years after 1969 but the final dates fall before 1970. Could turn off the overflow detection for centrally located years but that's more work. But it will parse [2100,12,13,23,59, -2147483648] and [1845, 1, 1, 0, 0, 2147483647] properly... i think. =^_^= -- '''[[User:Strife_Onizuka|Strife]]''' ([[User talk:Strife_Onizuka|talk]]|[[Special:Contributions/Strife_Onizuka|contribs]]) 06:28, 20 January 2010 (UTC)
:{{message}} I'll take a look in a bit, and I do like the integer division and bit shift solution in the unix2stamp, much cleaner... in the other, subtracting out 68 less to make the entire range positive... I like that part, shouldve done it from the start (it was converted from a quickie 1970+ version that I think argent did) although I had capped the dates to provide symmetry with the opposite function (since it's much easier to cap that one on a particular day, and 19 days on the edge seemed a small loss, vs detecting up to the last available second)... haven't checked the leap day / month detection in the loop replacement but I'll assume it's good until I double check. ps, I appreciate the fixes (always something to be learned) but can we separate out revisions that are more than corrections or order changes... it makes it harder to compare versions side by side (as the wiki only gives changed lines)... not complaining, I appreciate the feedback...

:: As I was reading the code, I was like "this code is so evil I think it is something I must have done in a past life". I really enjoy niggling away at code like this, reducing it to it's bare essentials. With that loop, once I saw that the sister function shared it, it made sense why you used it, symmetry. Yeah I agree with you about the comparisons being easier but it all sort of rolled out all at once; it didn't help that I pushed allot of the adjustment math through multiplications and divides. P.S. This version I posted I did check (in LSLEditor, with only minor mods, casting the bools to ints), I wanted to make sure I didn't screw up the math somewhere. P.S.S. I was considering replacing the (i * 30) with (i << 5) - (i << 1) cause it would be theoretically faster to execute but I didn't because it would probably take longer to setup the registers. P.S.S.S.

Anyway, Nandana Singh has asked me to help with the admin and distribution for nPose, and I'd like to take up your suggestion of posting the code in the wiki as well as continuing to distribute it in world via the GridShout system.

Anylyn Hax 13:34, 28 July 2007 (PDT)

The following headers will be present, usable by scripts running on the HTTP server if the scripting language allows you to access the headers.

An PHP example on how to check to see if the call came from the main grid:
<?php
if ($_SERVER["HTTP_X_SECONDLIFE_SHARD"] == "Production") {
echo 'You are using the main grid';
} else {
echo 'You are not using the main grid';
}
?>

== Odd format for header names ==

Why are the headers listed as HTTP_SOME_HEADER_NAME, when the sent headers are in the format Some-Header-Name? Is there some benefit to putting false values that match conventions used by CGI, but aren't actually correct?
* This is because you are looking at a global property with a lot more information than just headers. Some functions like listed below handle the stripping of the HTTP_ information, but you could also just use substr to remove the HTTP_ [[User:Wouter Hobble|Wouter Hobble]] - 4 July 2008

I am aware that the example given above works, but (assuming that you're using mod_php) this would too, and reflects the real header names:
<?php
$headers = apache_request_headers();
if($headers['X-SecondLife-Shard'] == 'Production')
{
print "You are on the main grid.";
}
else
{
print "You are on a preview grid.";
}

Additionally, the current information does not show the capitalisation, thus further confusing the matter.

|notes=If for some reason while using llHTTPRequest/http_response you are unable to parse a known good RSS feed or some other form of web contents, you will need to work around it outside of SecondLife. This is unlikely to change in the near future since checking the headers requires more overhead at the simulator level.

You may find that some web servers return either a null or a nonsensical result when llHTTPRequest is used, even though the same URL in a PC web browser returns the expected result. This may be due to the fact that the llHTTPRequest User Agent string is not recognised by some web servers as it does not contain "Mozilla", which would identify it as a web browser instead of, for example, a Shoutcast or an RSS client. A workaround is to append " HTTP/1.0\nUser-Agent: LSL Script (Mozilla Compatible)\n\n" or similar to the URL string, which will kludge the HTTP request to look like it originates from a web browser.

CGI environments may place the headers into variables by capitalizing the entire name, replacing dashes with underscores, and prefixing the name with "HTTP_", e.g. "HTTP_X_SECONDLIFE_OBJECT_NAME". PHP $_SERVER variables do this as well.

Apache can include the headers in its logs, using the CustomLog and LogFormat directives. See [http://httpd.apache.org/docs/2.0/mod/mod_log_config.html#formats the docs] for details on the syntax.

== Windlight? ==

How will this be affected by windlight? --[[User:Lavender Arrow|Lavender Arrow]] 09:33, 19 February 2008 (PST)

== either sync or don't bother ==

''which is why different clients can see different cloud formations and de-synchronizes cloud view from the server over time.''

LL should either lock the sync of cloud formations across all users, or they should not bother trying to sync at all and just generate cloud formations local to the client only. A halfway implementation that doesn't keep in sync ultimately just wastes bandwidth vs just a randomized clientside cloud generator that needs no bandwidth. [[User:Scalar Tardis|Scalar Tardis]] 20:26, 28 May 2008 (PDT)

:The clouds refered to are the particle like clouds and not the shader clouds (windlight). That aspect of the documentation hasn't been updated, most likely because nobody cares enough to ask LL how clouds currently work. It's totally moot considering the user can override the windlight settings. It's one of those little things that nobody really cares about. The stars fit into much the same category. -- [[User:Strife Onizuka|Strife Onizuka]] 00:18, 29 May 2008 (PDT)

== Errors in notes? ==

"Values returned above 1.0 - 2.0 indicate rainfall, but the option for rain is not currently implemented so values are capped at 1.0."

Minor point really, seeing as how this function is virtually useless except perhaps as a generator of not-so-random numbers that kinda "flow"...

It ''does'' return values greater than 1.0, and the phrase "above 1.0 - 2.0" is confusing; I think it's trying to say "in the range 1.0 - 2.0". I'm too ignorant of the inner workings of SL to be comfortable fixing this without moral support. [[User:Pete Olihenge|Pete Olihenge]] 21:56, 3 February 2010 (UTC)

:Good catch. The bulk of the documentation was written... oh $#!7. It's almost identical to the LSL Wiki documentation. Looking at the revision logs and the revisions themselves the good news is that they were both (mostly) by the same person. Tracking down the source of the content and properly attributing it is a monumental task (as I have my doubts about the authorship of the original info). We can however rewrite the content and use the original sources cited for our own. Since Cid contributed much of the content to both pages, we only need to worry about the contributions that weren't his. -- '''[[User:Strife_Onizuka|Strife]]''' ([[User talk:Strife_Onizuka|talk]]|[[Special:Contributions/Strife_Onizuka|contribs]]) 01:10, 4 February 2010 (UTC)

::Thanks, Strife. I've changed it to what I think is correct. It's sad that this and llGetSunDirection don't work properly; I was toying with an idea for a sundial that didn't use a clock as its basis. There would be possibilities for some nice meteorolgical and astronomincal toys if the functions worked - I'm sure I saw Orion the other day while watching a sunrise. And having just been sailing, the chaotic nature of the SL wind also means one has to rely on a third-party to provide something useable. [[User:Pete Olihenge|Pete Olihenge]] 01:37, 4 February 2010 (UTC)

:::P.S. I couldn't help but laugh when I though of SL Astrology.

::::Thanks for redoing the whole page - I was thinking about that myself. The sunrise was unspectacular; I was trying to reconcile the time of day, llGetSunDirection, the rendered sun direction and the rendered lighting effects. I think I've given up on getting anywhere with that. It seems the only useful environmental metrics are time dilation and sim FPS. Go on, give it to me straight: the starfield is entirely random and Orion is a programmer's joke? (It did prompt me to scan the heavens more closely but I'm no astronomer and I couldn't find either Cassiopea or Ursa Major.) [[User:Pete Olihenge|Pete Olihenge]] 11:35, 4 February 2010 (UTC)

:::::You got half of it, the pattern of stars resembling Orion must have been a random occurrence. I'm so sorry :-( I wish SL had a static star-field too.

|notes= How clouds work:

* SL features a cellular automata-based weather system.
* There are 16x16 square cloud "cells" per sim (which means each is 16x16m in size).
* The cloud density data is sent from the server to the client once every time the agent connects to a simulator via logging in or teleporting into a simulator.
* The client attempts to render clouds from the cloud algorithm results sent from the server, which is why different clients can see different cloud formations and de-synchronizes cloud view from the server over time.
* The Z value in the vector is irrelevant (clouds are always between about 180-200m absolute height).
* It returns a value between 0.0 and 2.0, with 0.0 being no clouds, and 1.0 very dense clouds. Values returned in the range 1.0 - 2.0 indicate rainfall, but the option for rain is not currently implemented.
* Clouds and wind are related.

The cloud seed/growth/dissipation algorithm uses a solenoidal vector field, which is a vector field with zero-divergence: {{noWrap|∇ · v {{=}} 0}}

This condition is satisfied whenever v has a vector potential A, because if {{noWrap|v {{=}} ∇ ⨯ A}} then {{noWrap|∇ · v {{=}} ∇ · (∇ ⨯ A) {{=}} 0}}

{{LSL Header|ml=*}}
{{LSLC|}}{{LSLC|Types}}

=Integers=
The integer data type is a signed 32 bit value between −2,147,483,648 and +2,147,483,647 (that is 0x80000000 to 0x7FFFFFFF in hex). Integers are whole numbers. The fractional datatype is the [[float]].

[[DEBUG_CHANNEL]] can be used as a constant for the maximum integer (for that is the value it is defined as).

==Examples==
All of the following are integers:
<lsl>integer firstInt = 5512623;
integer secondInt = ACTIVE;
integer thirdInt = 0x61EC1A;
integer fourthInt = -160693;</lsl>

The following are NOT integers, use {{LSLG|float}} for them:
<lsl>
integer decimalValue = 125.2; // ERROR : Type mismatch -- Integer literals can't have a decimal.
integer bigValue = 3147483647; // An undocumented way to say -1,147,483,649 // Integer literals can't be larger than 2,147,483,647.
integer biggerValue = 10123456789; // An undocumented way to say -1 // Integer literals can't be larger than 2,147,483,647.
</lsl>
