Legacy web pages of Axel Beckert

Since I'm no more active at the Fachschaftsrat Informatik of the University of Saarland anymore, I have transferred all my university time legacy web pages from http://fsinfo.cs.uni-sb.de/~abe/ to this interim host at http://fsinfo.noone.org/~abe/ with only minimal modifications, mainly e-mail addresses.

Most pages on this interim host won't be updated anymore until they are moved (and redirected) step by step to their future home somewhere under http://noone.org/.

Please also note that my former e-mail address ~~abe@fsinfo.cs.uni-sb.de~~ is no more valid. Use abe@deuxchevaux.org instead.

wApua features:

Interprets most WML tags, including:

Anchor- and do-links;
Templates; (And in comparison to WinWAP 2.x, it interpretes the <noop/> tag correctly!)
Tables;
CDATA sections;
Images;

Proxy support via environment variables;

Image support (WBMP type 0) due to internal WBMP to XBM converter;

Timer support;

Emacs-, vi- and Netscape-style (both X- and Windows-Netscapes) key bindings;

Stop button and right-click context menu; ^NEW

Status line showing file size (if appropriate, also image dimension or number of cards), how much data has been downloaded, link URLs, button functions (incl. URLs in case of forward and back buttons and WML do-buttons).

Highlighting of links, if the mouse is over them (as the hover feature in MSIE and Opera);

Includes a WBMP to XBM converter script for command line use;
This converter is thought as an example for how to use the wApua WBMP to XBM converter in other Perl scripts. If you're looking for some professional and free image converter, which can read and write WBMPs, have a look at ImageMagick. (FAQ: Why doesn't my ImageMagick support WBMP?)

Simple WTAI (Wireless Telephony Application Interface) and Telephone Call URL (RFC 2806) support; ^NEW
Surely I haven't programmed some telephone, but wApua shows you, what a mobile phone would do with some wtai: or tel: URL. :-)

RAM cache;

Simple per-request authentication;

Comfortable installation via ExtUtils::MakeMaker;

Configuration via configuration file ~/.wApua.rc; ^NEW

Features, coming in one of the next wApua releases:

<head> and <meta> tag support;

Forms & states

Caching of authentication credentials.

Send Referer header

Verification of valid WML tag nesting according to the DTD (which actually none of the emulators know to me).

display WMLC / decompile WMLC

Detailed warnings about broken WML code, bad and non-DTD-conform tag nestings, as well as URL scheme which are unsupported by WAP (like mailto: and ftp:).

Global configuration file, e.g. /etc/wApuarc or something like that.

Planned features, but not with highest priority:

(unsorted)

invoke external programs for showing HTML or sending mails (will at least include standard configuration for Netscape's X remote control and the text console browsers lynx, w3m and links). Of course, wApua will support the $BROWSER variable.

language and color schemes

Different colors for visited links.

onevent support

Submission to CPAN.

Long-Time Plans / Ideas for future releases:

Debian packages

accessing WAP pages by other protocols than those actually supported by libwww-perl (that means HTTP and FTP)

rewrite the rendering engine based on some XML parser instead of the slightly raped HTML::TokeParser, which is actually used...

Perhaps add a (curses based, still Perl written) text-only WML browser.

Perhaps a (SSI-, PHP- and EmbPerl-aware) WML compiler

Some more WBMP tools.

Adjusting the link colors of the wApua web pages to matching the colors, that are present in the wApua logo on top of these pages. ;-)

The wApua source code, the wApua web and the wApua WAP pages were all written with GNU Emacs.
The wApua logos were made with The GIMP (PNG and JPEG only; there are no GIFs) and ImageMagick (WBMP).
This page is best viewed with any browser, including text-only browsers like Lynx, w3m or links.


Just another little Perl script... :-)
