Lynx V. 2.8 for
OS/2 Released!

JasonMcBrayer just releases Lynx V. 2.8 for OS/2 and the archive (os2lynx2_8.zip, 1,4 megabyte) was uploaded on Hobbes. Lynx Version 2.8 is the latest "official" release. This release is based on the lynx2.7.1ac-0.118 development code set, and includes bug fixes through March 10, 1998.

Why Lynx?

Lynx is a full featured text-oriented browser for the World Wide Web.
Though the trend in recent years has been towards graphical browsers, there are still many good reasons for using Lynx. Lynx can be used to format WWW output for users with special needs, such as the visuallyimpaired. Lynx is also much faster than any other browser out there, and is good for doing quick lookups on URLs from a newsreader, for example. Lynx lets you cut through the style and get right to the substance.

What's New?

Lots!

Here are some of the major chages since Lynx 2.7.1. The changes since
Lynx 2.4, which Lynx/2 was based on are too many to name.
* New Sorta-SGML parser (^V to toggle between new and old parser)
* Ncurses color-support (works in OS/2 window or xterm). Two ways of selecting colors: color for types of emphasis in lynx.cfg (what used to be bold can now be red, for example), or experimental color-styles allow you to set color for any HTML element using a stylesheet.
* External commands: use wget or ncftp to do external downloads while you keep browsing in Lynx. Or start up a new Lynx window rom a hyperlink within Lynx!
* Experimental partial display code lets you see long pages as they download.
* Lots of small interface tweaks and bug fixes.
* In 2.8.1 and later, OS/2-EMX will be a supported platform for
Lynx; no need to patch sources to recompile.

Installation

Hardware and Software Requirements

Hardware

* An IBM-compatible PC capable of running OS/2 2.1 or later with TCP/IP
* In effect, a 386sx or better with at least 8 MB of RAM.

Software

* OS/2 2.1 or later (I think...should definitely be OK on Warp 3 or later).
* An HPFS partition, as I haven't made any allowances for FAT filenames. Actually, FAT might work, but you won't have any online help.
* IBM TCP/IP 2.0 or later (?) Warp 3 IAK, Warp Connect, and Warp 4 all fit the bill.
* EMX runtime 0.9c or later.
* GNU File Utilities. You need at least 'cp', and I'm not sure what all else.

Installation Procedure

This is probably a little harder than it needs to be right now. I'll try to make it as straightforward as possible.
1. Unzip the Lynx 2.8 package into a directory. You've probably already done this.
2. If you haven't installed the EMX runtime or the GNU file utils, now is a good time. If you don't have the GNU Fileutils and don't want to install them, copy the file lcp.exe to cp.exe in the same directory as your lynx.exe.
3. Copy lynx-std.exe and/or lynx-sty.exe to somewhere on your path, or to its own directory. Put lynx.cfg somewhere;if lynx has its own directory you may want to put it there. This build of Lynx will look in the %HOME% directory (the directory specified by the HOME environment variable) for both lynx.cfg and lynx.lss. Lynx.lss should go in %HOME%. You need to put the helpfiles somewhere, too. If lynx has its own directory, put their directories under it.
4. Move the terminfo directory somewhere. Lynx will look for terminfo files either in %TERMINFO% or in %HOME%/.terminfo. Lynx will also use TERMCAP if it can't find the terminfo files; if you use termcap, color won't work.
5. Set some environment variables in your config.sys:
+ set HOME=x:/pathname (where you want personal configuration files, signature files, etc to go)
+ set TMP=x:/tmpspace (a temporary directory)
+ set TERMINFO=x:/terminfo_path (where you moved the terminfo directory, e.g. set TERMINFO=d:/emx/terminfo.)
+ set TERM=something (where something is a terminal type supported by terminfo and hopefully also termcaps: "ansi" is a reasonable if unaesthetic value.)
+ set WWW_HOME=scheme://some.random.url/ (the URL you want Lynx to load on startup. For example, set WWW_HOME=http://www.ibm.com/.)
+ set LYNX_CONFIG=x:/pathname/lynx.cfg (Path where you put lynx.cfg; if lynx.cfg is in %HOME% you don't have to set this.).
6. Edit your lynx.cfg file to suit your needs. Some things in here must be changed to suit your configuration (especially your domain, and the location to helpfiles, etc.).
7. Reboot to activate your environment variables; make a desktop object for Lynx if you wish. Alternatively, instead of modifying config.sys and rebooting, you can make a lynx.cmd file containing all of the environment variable settings and running Lynx.
8. Happy Lynxing!

There are two Lynx executables included in this package. Lynx-std.exe is built to use the standard method of color selection; look in lynx.cfg for the COLOR directives and associated comments.
Lynx-sty.exe is built to use color styles for color selection; edit lynx.lss to set colors for particular HTML elements. The two methods have their own strengths and weaknesses. The color-styles version gives you finer control over what colors are used for what kinds of text, but you can't really set the main/default background color with it. It is also hard to predict exactly what results you will get when various HTML tags are combined! The color-styles code is experimental.
The standard method lets you use fewer colors, but it lets you set the overall background color, for example. In my experience, the standard method is better in OS/2 windowed or full-screen sessions, while the color-styles method is better in an xterm. In fact, it looks [9]really good in rxvt.

Installation from sources

In order to compile Lynx for OS/2, you need a number of different packages. You can get either the OS/2-specific source distribution (from Hobbes or probably whereever you got this package), or get the latest sources from [10]the Lynx experimental distribution directory.
You will need the EMX/GCC compiler, [11]Autoconf for OS/2 and
[12]Ncurses for OS/2. Unpack the Lynx source. Use autoconf to rebuild the configure script (this will require an extremely complete set of unix-like utilities for OS/2). Run configure, and edit the resulting lynx_cfg.h to your satisfaction. Most things will be fine, but make sure that the names of programs (cp, gzip etc) are correct; that's the only thing configure is likely to get wrong. Run 'make', and everything should go perfectly smoothly.

Getting Help

The best place to start looking for help is in the Lynx help files. If you have Lynx set up correctly, you can browse them just by hitting h' or '?'. If not, try looking at them with WebExplorer.

Lots of good information is available from [13]Lynx Links. I may have more specific information about Lynx for OS/2 available from my [14]Lynx page. If you're totally stuck, you can [15]email me, but please don't send me any general Lynx questions, etc; just problems, suggestions, or compliments regarding the OS/2 port.

Bugs

These are the bugs I know about:
* Basic dired support works, but many features don't work: you can't move or change the permissions on files.
* There are some glitches in the display with the standard method of color selection. If the screen gets missed up and ^L doesn't clear it up, try typing v (for the bookmarks page) and ^G to cancel. I think it's an ncurses problem; maybe just the terminfo files.
There are also some display problems in an xterm; use TERM=x10term or TERM=rxvt to get around it.

If anyone finds any other bugs, [16]let me know. In particular, I may well have missed any number of places where Unix-like pathnames are expected.
