This is a port of Lynx 2.8.9dev.16 to MSDOS/DJGPP.
Lynx is a fully-featured World Wide Web (WWW) client for users running
cursor-addressable, character-cell display devices such as vt100 terminals,
vt100 emulators running on character-cell display. It will display Hypertext
Markup Language (HTML) documents containing links to files on the local system,
as well as files on remote systems running http, gopher, ftp, wais, nntp,
finger, or cso/ph/qi servers, and services accessible via logins to telnet,
tn3270 or rlogin accounts.
DJGPP specific changes.
=======================
This port is based on the current develop code of lynx (aka lynx2.8.9dev.16)
available as:
http://invisible-island.net/datafiles/release/lynx-cur.tar.bz2
The code has been adjusted to detect at runtime if LFN support is available
or not. If LFN support is available then the original posix style file names
will be used else DOS compatible ones will be used.
The port will use cp850 as default code page instead of using iso-8859-1 as
it is in the current code. It is clear that having iso-8859-1 on plain DOS
as character set is useless as soon as spanish, german or other non-english
texts shall be displayed. You can always select another character set by
either setting the corresponding environment variable or by editing lynx.cfg
acordingly.
The current version of lynx requires that the HOME environment variable is
set to a writable directory or it will refuse to start. To alleviate this
situation, if HOME is not set, the current directory will be used instead
by this port version.
The port has been configured using the configure script provided by the
source package. This means that neither old DJGPP specific scripts nor
makefiles distributed by the package have been used. A lot of the porting
work has been invested in the DJGPP specific configuration scripts.
This port has been configured to be compiled with BZIP2, ZIP and PDCURSES
support. This means that if you want to recompile the preconfigured sources
you must have installed the following ports:
ftp://ftp.delorie.com/pub/djgpp/current/v2apps/bz2-106ar2.zip
ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlb1211b.zip
ftp://ftp.delorie.com/pub/djgpp/current/v2tk/pdcur34a.zip
The port has been configured and build without NLS support enabled. To enable
this feature, the latest ports of libiconv and gettext must be installed:
ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/licv114br2.zip
ftp://ftp.delorie.com/pub/djgpp/current/v2gnu/gtxt192b.zip
If you prefer NLS, then reconfigure the sources passing the nls flag to the
config.bat file.
The port has been configured with OPENSSL support. OpenSSL support requires
installing the WATT-32 port. The following ports have been used:
ftp://ftp.delorie.com/pub/djgpp/current/v2tk/ssl102kb.zip
ftp://ftp.delorie.com/pub/djgpp/current/v2tk/wat3222br6.zip
No other versions have been tested. To be able to use this program compiled
with OpenSSL and WATT-32 a noise source must be installed. A noise source
can be obtained as:
http://www.rahul.net/dkaufman/noise063a2.zip
If for some reason you decide to reconfigure the source package, then you
will have to set the WATT_ROOT environment variable to point to the directory
where the headers and the library reside. This is:
set WATT_ROOT=/dev/env/DJDIR/net/watt
To be able to run the program, configuration files are expected to be found
at their canonical place. This is the /dev/env/DJDIR/etc directory. The
configuration files lynx.cfg and lynx.css are stored in the /etc directory
and reflect, to certain extent, the conditions during the configuration and
compilation process of this port. You may need to adjust the entries to fit
your requiriments. If lynx.cfg and lynx.css are not found at their canonical
place then the program will try to load them from the installation directory
of lynx. To run the program, a working version of wattcp.cfg is required.
This file is __NOT__ distributed with this port. That file will reflect
your network environment and hardware. It is the user's job write one that
matches his environment. As a starting point you can use the one distributed
with the WATT-32 port. Please note that the location of wattcp.cfg must be
specified by setting the WATTCP.CFG environment variable. This can be done
either in the environment, in autoexec.bat or in djgpp.env. If the file
cannot be found at any of the canonical places the program will try to load
it from the installation directory of lynx.
To be able to run the program, a DOS packet driver (PKTDRVR) is required.
This may be obtained from the card manufacturer or from one of the archives
of packet drivers (such as "http://www.lanet.lv/simtel.net/msdos/pktdrvr-pre.html"
or "http://ftp.freenet.de/pub/ftp.simtel.net/pub/simtelnet/msdos/pktdrvr/").
Even when only browsing local files, a NULLPKT packet driver is required like
nullpkt.zip. The zip file can be downloaded as:
http://www.jumpjet.info/Application-Software/DOS/Hardware/2/NULLPKT/NULLPKT.zip
The lynx executable itself handles http:, https:, ftp:, file:, news:, nntp:
and gopher: protocols. You will need external programs if you want to access
telnet:, tn3270:, or mailto: URLs. In this case a port of kermit may be required.
Please note that lynx does _NOT_ support javascript at all. So nothing will
work that requires this feature. If you need this, look for a different text
web browser.
It is important to realize that this port is a _PURE_ DOS port. If for some
reason you want to use lynx under Windows, you should download a windows port
of lynx.
If you decide to use this port as stand alone program then you __MUST__ set
the following environment variables to point to the required configuration
files:
LYNX_CFG Set to the full path and filename for lynx.cfg
LYNX_LSS Set to the full path and filename for lynx.lss
WATTCP.CFG Set to the full path for the WATTCP.CFG directory
SSL_CERT_FILE Set to the full path and filename for your file of trusted
certificates
As a last resort, if the above environment variables are not set, the program
will try to load those files from its installation directory. There is also
a batch file stored in the /share/lynx_doc/samples directory that shows how
to run lynx as a stand alone application.
The DJGPP port now checks the OS version it is running on. If it is equal
or less than MSDOS 6.22 the double quotes around the file name passed to
edit.com will be removed. If this is not done, edit.com refuses to start.
For OS like Win95 and above this is not necessary. edit.com is the editor
used by lynx at last resort. The program's behaviour is not changed if an
editor different from edit.com is selected in lynx.cfg.
The DJGPP port now checks if LFN support is available. If available then
files with a leading dot are allowed/supported in case that this has been
allowed by setting NO_DOT_FILES to FALSE in lynx.cfg. In all previous
versions, the setting of this value had absolute no influence in program's
behviour if compiled with DJGPP.
I have tested this port by trying to access all sites that are listed in:
http://royal.pingdom.com/2012/06/25/using-web-browser-lynx-visit-top-websites/
and I have experienced no issues. I have also accessed some german and spanish
sites to check if the special native characters are correctly displayed and
I have found no issues. I have also accessed www.delorie.com to check if the
ftp support works well and if the cvs repository can be accessed via cvsweb
interface and everthing works flawlessly. Of course, the mail archives can
also be accessed without issues.
Please note that I am not a lynx user. I have ported it as a real world test
for the OpenSSL and WATT-32 ports.
As usual, all djgpp specific files (diffs, README files, etc.) are stored in
the /djgpp directory. The sources have been configured to be build in the
"_build" directory. If for some reason it does not work for you, delete it
contents and configure from scratch again.
Please read the docs very __CAREFULLY__ to become familiar with the product.
Here is an extract of the NEWS file showing the user visible changes from
the last port (Lynx 2.8.9dev.14) to this one:
-------------------------------------------------------------------------------
2017-07-10 (2.8.9dev.16)
* modify configure script to warn if NLS cannot be configured, and disable
the feature rather than leaving it partly configured and failing during
the build -TD
* modify configure script to allow pre-set $MSGFMT and $XGETTEXT variables to
to used to build the NLS configuration using system's native NLS support -TD
* convert po/zh_TW.po to UTF-8 to work with Solaris10, which lacks big5 -TD
* build-fix for OSX Panther, which has PRId64 but not SCNd64 (patch by Martijn
Dekker).
* modify po-makefile to use msgmerge to align with lynx.pot, and also use sed
to update some obsolete homepage URLs in translations -TD
* add a note in the comments for INCLUDE in lynx.cfg regarding the default
directory searches LYOpenCFG(), added in 2.8.4dev.20 (Debian #818047) -TD
* add a check to ensure that HTML_put_string() will not append a chunk onto
itself (report by Ned Williamson) -TD

trimmed, e.g., trailing lines as well as the special case for collapsing
br-tags. Leading blank lines at the top of the document are untouched.
+ modify limit for trimmed lines to retain as little as 1 line; previously
the trimming would go no smaller than 2 lines.
