Welcome to Rosetta Code! I founded RC around a year ago, and still do most of the administrative work. Thanks for your code contributions. I'm curious, though, how did you hear about RC? --Short Circuit 10:44, 23 February 2008 (MST)
- Hi, thanks. I heard from a forward message posted at Digital Mars D newsgroup about a month ago. -badmadevil 03:03, 24 February 2008 (MST)

Good job with the mylang templates. I had done as well as I could before, but these are better. --Mwn3d 13:52, 22 March 2008 (MDT)

Not Implemented Tasks by Language
Hello. IIRC, it has been mentioned an idea to display a page of tasks not implemented by a specific language (It is from Ian Osgood's wishlist), it seems no such page at Rosetta Code yet. I've coded a dirty hack of such page using PHP.
This version should preserve Rosetta Code's pages look and feel, and may be better integrated into RC site.
Bugs fix notes :
- When PHP flag allow_url_fopen is enabled, it is possible to read contents from RC Site via local server. Then, by directly testing with RC Site, many bugs were found;
- fixed, it seems that articles in tasks or languages' pages have at least 3 version of url. In most cases, they refer to the same file, but it seems some are not (may be re-direction?). Previously, some url can be accessed while other cannot, if only using one version of url; now all 3 version is tried. The version of '/w/index.php?title=' has highest priority, so that page like C++ will not mistaken by C page;
- changed, it seems I'm wrong again. All pages can be accesses by '/wiki/Category:' version's url, only that to not mistaken C++ page with C page, url extracted from RC page have to be encoded 2 times. In most case, this '/wiki/Category:(encoded-url)' can reach the page correctly, only pages like PL/I, PL/SQL need 1 decode. No more other version of url is needed. -- badmadevil 09:14, 17 June 2008 (MDT)
- fixed, previously, required link nodes to be got by xpath are assumed to be inside a table, but it is found that language page having 7 or less task completed didn't use a table; the later case is dealing with another proper xpath;
- some pages have not any task completed, eg. assembler, pike, JoCaml. They are treated as error loading page, rather than display all tasks from Task-list page;
- unsolved, there are unknown errors on parsing pages of JScript.NET & Visual Basic.NET as DOM. They can be load as DOMDocument (so that it is not a problem of url, eg.wrong encoding of url string), but can't get the required Node by getElementById inside the DOMDoc;
- fixed, it is really a problem of wrong encoding, the 'dot' is not properly encoded, and the page loaded I said previously is the create new articles page. It has been fixed. All bugs should has been fixed. -- badmadevil 12:22, 16 June 2008 (MDT)
- Usage, this version need not config, as long as allow_url_fopen is enabled. Place this script in a server (local server or RC Site) some where can be access from www, and that is it.
- Tested with PHP 5.2.1

Hope it can be a temporary solution. -- badmadevil 12:33, 22 June 2008 (UTC)
