Takat Su: Added the To Do in the comments.

== Name2Key ==
'''This is an update to Maeva Anatine's excellent suggestion for an updated name2key function. Rather than overwrite all her work, I created this page. The idea is DEFINITELY hers - I just am creating an alternate implementation.
'''

Still missing Name2Key functions in your code? Still relying on external databases that are not always up to date with latests SL subscribers?

Well now you can solve this by yourself, within your LSL script! All you have to do is to rely on LL Search engine!

I put a kind of "library" and a sample of usage for your convenience

To use, you make an llHttpRequest to the application running on the Google Application Server (a free service for moderate users). The URL looks like this: http://name2key.appspot.com/?name=firstname%20lastname i.e. the first name of the person you want to look up is separated from their last name by "%20" (this is how the space character is coded in URLs). The application doesn't care if you get the case correct. The application will format the body of the return as follows: firstname lastname:key, where firstname and lastname will be capitalized correctly and the key is either the key for the person or the null key (00000000-0000-0000-0000-000000000000). It really isn't much code if you prefer to code it into your main script rather than rely on an external script for the lookup.

<b>To Do</b>: Alter the python code so that it fails gracefully if the name given in the URL does not exist or if Linden Search is down.

The main difference is that I wrote a an app for the google app engine that act as a relay. Since I was going that far, it also parses the return, strips out all the extraneous stuff and just returns you the name and key separated by a colon.

EDIT : Looks like the Lindens have either broken or blocked this function. It works from my browser, however from LSL I get an error page containing this message "Access control configuration prevents your request from
being allowed at this time. Please contact your service provider if
you feel this is incorrect." - Darling Brody.

EDIT : Yes you're right Darling. It seems they've blocked this access from within the world... I still wonder why, especially as there are some workarounds to this...
Anyway I discovered there is a JIRA issue for this. Please vote for the unblock !

EDIT : OK after having read this article from LL: http://wiki.secondlife.com/wiki/SearchAPI, it seems proxy usage is allowed. So I modified the upper code in order to go through a proxy machine and it works again :)
- Mae

EDIT: After review, it appears the Yahoo Babelfish proxy you are using above does not return the results expected. I rewrote this to allow different proxies by a simple configuration. This now uses Google instead of Babelfish by default. This does not, however, work for any avatars that do not have a Profile filled out (this is due to a limitation of the Googly proxy we're using here). I'm researching this and trying to see if there is a better proxy to use.

This version can handle multiple requests at once. Replies have changed slightly, as the found key is returned in the "key" field instead of the message field. In addition, failure of any kind results in a NULL_KEY being returned, and status information is returned in the message field. - [[User:Sensei Schism|Sensei Schism]]

EDIT 2009-Mar-08: Sensei, I reused your version here above and took back BabelFish as Google one is unable to retrieve all links (doesn't recognized correctly the secondlife:/// link). In addition, I made some slight changes as LL recently changed their search engine. This version now works properly.

EDIT 2009-Aug-27: LL changed the search URL from '''search'''.secondlife.com/client_search.php to '''vwrsearch'''.secondlife.com/client_search.php
[[User:ab Vanmoer|ab Vanmoer]]

EDIT 2009-Sep-04: The problem with the proxy you have there is that it translates the name as a french name, and if it happens to be a real french word, then the name gets changed to that. for example the last name of Vella got changed to Calved, so no match was made. PS. I also found some names had been surrounded by bold tags. So, since i have a few websites i can run PHP on i got [http://sourceforge.net/projects/php-proxy/ PHP Web Proxy] and point to it. Also, I used: body = llDumpList2String(llParseStringKeepNulls(body, ["<b>", "</b>"], []), ""); to remove the bold tags.
-Spritely Pixel

EDIT 2009-Sep-19: Changed the translation from french to korean on the theory that there are very few names that contain valid Korean characters, thus the translation should just pass straight through. Changes were: 1. Change the proxy url to use ko_en instead of fr_en. 2. Change the profile search string from "Resident profiles" to "Resident profile" (note change from plural to singular) and changed the name offset to account for the (now missing) 's'. Also note that Babel will sometimes return an advertising page instead of the translation. Thus, you should be prepared to retry the search a few times if you get a page that doesn't make sense.[[User:Takat Su|Takat Su]]

EDIT 2009-Sep-20: Got fed up with the babel translation thing. Apparently, if you make too many requests, Yahoo throttles you for between 2 and 24 hours. So I made a relay for the google appspot engine and replicated this page with the new code here: http://wiki.secondlife.com/wiki/User:Takat_Su/Name2Key [[Takat Su|Takat Su]]

Change the profile search string from "Resident profiles" to "Resident profile" (note change from plural to singular) and changed the name offset to account for the (now missing) 's'. Also note that Babel will sometimes return an advertising page instead of the translation. Thus, you should be prepared to retry the search a few times if you get a page that doesn't make sense.[[User:Takat Su|Takat Su]]

EDIT 2009-Sep-20: Got fed up with the babel translation thing. Apparently, if you make too many requests, Yahoo throttles you for between 2 and 24 hours. So I made a relay for the google appspot engine and replicated this page with the new code here: https://wiki.secondlife.com/wiki/User:Takat_Su/Name2Key [[Takat Su|Takat Su]]

Still missing Name2Key functions in your code? Still relying on external databases that are not always up to date with latests SL subscribers?

Well now you can solve this by yourself, within your LSL script! All you have to do is to rely on LL Search engine!

I put a kind of "library" and a sample of usage for your convenience

To use, you make an llHttpRequest to the application running on the Google Application Server (a free service for moderate users). The URL looks like this: http://name2key.appspot.com/?name=firstname%20lastname i.e. the first name of the person you want to look up is separated from their last name by "%20" (this is how the space character is coded in URLs). The application doesn't care if you get the case correct. The application will format the body of the return as follows: firstname lastname:key, where firstname and lastname will be capitalized correctly and the key is either the key for the person or the null key (00000000-0000-0000-0000-000000000000). It really isn't much code if you prefer to code it into your main script rather than rely on an external script for the lookup.

you feel this is incorrect." - Darling Brody.

EDIT : OK after having read this article from LL: http://wiki.secondlife.com/wiki/SearchAPI, it seems proxy usage is allowed. So I modified the upper code in order to go through a proxy machine and it works again :)

EDIT: After review, it appears the Yahoo Babelfish proxy you are using above does not return the results expected. I rewrote this to allow different proxies by a simple configuration. This now uses Google instead of Babelfish by default. This does not, however, work for any avatars that do not have a Profile filled out (this is due to a limitation of the Googly proxy we're using here). I'm researching this and trying to see if there is a better proxy to use.

This version can handle multiple requests at once. Replies have changed slightly, as the found key is returned in the "key" field instead of the message field. In addition, failure of any kind results in a NULL_KEY being returned, and status information is returned in the message field. - [[User:Sensei Schism|Sensei Schism]]

EDIT 2009-Mar-08: Sensei, I reused your version here above and took back BabelFish as Google one is unable to retrieve all links (doesn't recognized correctly the secondlife:/// link). In addition, I made some slight changes as LL recently changed their search engine. This version now works properly.

EDIT 2009-Aug-27: LL changed the search URL from '''search'''.secondlife.com/client_search.php to '''vwrsearch'''.secondlife.com/client_search.php
[[User:ab Vanmoer|ab Vanmoer]]

EDIT 2009-Sep-04: The problem with the proxy you have there is that it translates the name as a french name, and if it happens to be a real french word, then the name gets changed to that. for example the last name of Vella got changed to Calved, so no match was made. PS. I also found some names had been surrounded by bold tags. So, since i have a few websites i can run PHP on i got [http://sourceforge.net/projects/php-proxy/ PHP Web Proxy] and point to it. Also, I used: body = llDumpList2String(llParseStringKeepNulls(body, ["<b>", "</b>"], []), ""); to remove the bold tags.

EDIT : Looks like the Lindens have either broken or blocked this function. It works from my browser, however from LSL I get an error page containing this message "Access control configuration prevents your request from
being allowed at this time. Please contact your service provider if
you feel this is incorrect." - Darling Brody.

EDIT : Yes you're right Darling. It seems they've blocked this access from within the world... I still wonder why, especially as there are some workarounds to this...
Anyway I discovered there is a JIRA issue for this. Please vote for the unblock !

EDIT : OK after having read this article from LL: http://wiki.secondlife.com/wiki/SearchAPI, it seems proxy usage is allowed. So I modified the upper code in order to go through a proxy machine and it works again :)
- Mae

EDIT: After review, it appears the Yahoo Babelfish proxy you are using above does not return the results expected. I rewrote this to allow different proxies by a simple configuration. This now uses Google instead of Babelfish by default. This does not, however, work for any avatars that do not have a Profile filled out (this is due to a limitation of the Googly proxy we're using here). I'm researching this and trying to see if there is a better proxy to use.

This version can handle multiple requests at once. Replies have changed slightly, as the found key is returned in the "key" field instead of the message field. In addition, failure of any kind results in a NULL_KEY being returned, and status information is returned in the message field. - [[User:Sensei Schism|Sensei Schism]]

EDIT 2009-Mar-08: Sensei, I reused your version here above and took back BabelFish as Google one is unable to retrieve all links (doesn't recognized correctly the secondlife:/// link). In addition, I made some slight changes as LL recently changed their search engine. This version now works properly.

EDIT 2009-Aug-27: LL changed the search URL from '''search'''.secondlife.com/client_search.php to '''vwrsearch'''.secondlife.com/client_search.php
[[User:ab Vanmoer|ab Vanmoer]]

EDIT 2009-Sep-04: The problem with the proxy you have there is that it translates the name as a french name, and if it happens to be a real french word, then the name gets changed to that. for example the last name of Vella got changed to Calved, so no match was made. PS. I also found some names had been surrounded by bold tags. So, since i have a few websites i can run PHP on i got [http://sourceforge.net/projects/php-proxy/ PHP Web Proxy] and point to it. Also, I used: body = llDumpList2String(llParseStringKeepNulls(body, ["<b>", "</b>"], []), ""); to remove the bold tags.
-Spritely Pixel

EDIT 2009-Sep-19: Changed the translation from french to korean on the theory that there are very few names that contain valid Korean characters, thus the translation should just pass straight through. Changes were: 1. Change the proxy url to use ko_en instead of fr_en. 2. Change the profile search string from "Resident profiles" to "Resident profile" (note change from plural to singular) and changed the name offset to account for the (now missing) 's'. Also note that Babel will sometimes return an advertising page instead of the translation. Thus, you should be prepared to retry the search a few times if you get a page that doesn't make sense.[[User:Takat Su|Takat Su]]

Name2Key in LSL

2009-09-19T15:39:45Z

Takat Su: Changed the translation from French to Korean to mitigate the "name is a french word" problem.

{{LSL Header}}__NOTOC__

Still missing Name2Key functions in your code? Still relying on external databases that are not always up to date with latests SL subscribers?

Well now you can solve this by yourself, within your LSL script! All you have to do is to rely on LL Search engine!
