Previously, each mapping between a codepage byte and a Unicode character was stored as a struct table_entry, which listed both the byte and the character. This representation may be optimal for sparse mappings, but codepages map almost every possible byte to a character, so it is more efficient to just have an array that lists the Unicode character corresponding to each byte from 0x80 to 0xFF. The bytes are not stored but rather implied by the array index. The tcvn5712 and viscii codepages have a total of four mappings that do not fit in the arrays, so we still use struct table_entry for those. This change also makes cp2u() operate in O(1) time and may speed up other functions as well. The "sed | while read" concoction in Unicode/gen-cp looks rather unhealthy. It would probably be faster and more readable if rewritten in Perl, but IMO that goes for the previous version as well, so I suppose whoever wrote it had a reason not to use Perl here. Before: text data bss dec hex filename 38948 28528 3311 70787 11483 src/intl/charsets.o 500096 85568 82112 667776 a3080 src/elinks After: text data bss dec hex filename 31558 28528 3311 63397 f7a5 src/intl/charsets.o 492878 85568 82112 660558 a144e src/elinks So the text section shrank by 7390 bytes.

ELinks - an advanced web browser ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ELinks is an advanced and well-established feature-rich text mode web (HTTP/FTP/..) browser. ELinks can render both frames and tables, is highly customizable and can be extended via scripts. It is very portable and runs on a variety of platforms. The ELinks official website is available at http://elinks.cz/ Please see the SITES file for mirrors or other recommended sites. If you want to install ELinks on your computer, see the INSTALL file for further instructions. A good start point is documentation files available in doc/, especially the file named index.txt. If you want to request features or report bugs, see community information at http://elinks.cz/community.html and feedback information available at http://elinks.cz/feedback.html. If you want to write some patches, please first read the doc/hacking.txt document. If you want to add a new language or update the translation for an existing one, please read po/README document. If you want to write some documentation, well, you're welcome! ;) Historical notes ~~~~~~~~~~~~~~~~ Initially, ELinks was a development version of Links (Lynx-like text WWW browser), with more liberal features policy and development style. Its purpose was to provide an alternative to Links, and to test and tune various new features, but still provide good rock-solid releases inside stable branches. Why not contribute to Links instead? Well, first I made a bunch of patches for the original Links, but Mikulas wasn't around to integrate them, so I started releasing my fork. When he came back, a significant number of them got refused because Mikulas did not like them, as he just wouldn't have any use for them himself. He wants to keep Links with a relatively closed feature set and merge only new features which he himself needs. It has advantages that the tree is very narrow and the code is small and contains very little bloat. ELinks, on the contrary, aims to provide a full-featured web browser, superior to both lynx and w3m and with the power (but not slowness and memory usage) of Mozilla, Konqueror and similar browsers. However, to prevent drastic bloating of the code, the development is driven in the course of modularization and separation of add-on modules (like cookies, bookmarks, ssl, scripting etc). For more details about ELinks history, please see http://elinks.cz/history.html If you are more interested in the history and various Links clones and versions, you can examine the website at http://links.sf.net/ vim: textwidth=80
