Using w3m on Cygwin

                                                                    2003/02/20

You can use w3m on Windows with a UNIX compatible environment "Cygwin". For
detailed information of Cygwin, See http://cygwin.com/.

Build

After w3m-0.2, patches for Cygwin have been marged to w3m packages. If you use
cygwin-1.1.4 or later, w3m shuould be build without any problems.

The newest version of termcap and ncurses package are recomended. Especially,
older versions of termcap have bugs in the entry for Cygwin which make the
screen collapsed. The problem was fixed in termcap-20001020-1.

Please make sure to execute ./configure before the make. The macros explained
in "Macros" are defined by ./configure, and they are nessary to make this
package. When you have some problem in making w3m, please check the points
below:

 o  Do make veryclean, then exec ./configure && make.
 o  Check gcc and binutils are properly installed. setup.exe might have
    finished without reporting any errors, though the download of package
    files was end in failure. In this case, you should try to setup again.

Using Cygwin with Win95/98/ME, configure will not run correctly when
environment variable CYGWIN includes "ntsec" and/or "ntea", because shell
scripts will not have executable attribute. It is recomended to remove "ntsec"
and "ntea" from environment variable CYGWIN to load cygwin1.dll for the first
time.

Macros

The macros below are defined in config.h for Cygwin environment.

USE_BINMODE_STREAM
    With -dump, -dump_{head,source,both,extra} option, output to stdout are
    done in binary mode. It might not been needed with cygwin-1.3.11 or later,
    but remained for safe.
    In common with Cygwin and EMX.
SUPPORT_DOS_DRIVE_PREFIX
    The path names are handled as file names when they includes drive letters
    like "C:", "C:/", "file://C:/", "file://C|/", and so on.
    In common with Cygwin and EMX.
SUPPORT_NETBIOS_SHARE
    URIs of common resources of NETBIOS in "//NETBIOSHOST/SHARE/PATH",
    "file://NETBIOSHOST/SHARE/PATH" format are handled as file: schema instead
    of ftp: schema.
    Only for Cygwin environments.
SUPPORT_WIN9X_CONSOLE_MBCS
    Search and line input to forms are supported. But input through IME is
    available only with the local console when TERM=cygwin, and environment
    variable CYGWIN is not include "tty". The restrictions avoid the problems
    of the DOS prompt of Win9x and tty layer of Cygwin. For WinNT, the macro
    doesn't change any behavior of w3m, IME is always available with local
    consoles.
    Only for Cygwin environments and LANG=JA.

Cooperation with Native Applications

When calling the Win32 Native Abblications, "File not found" errors might be
raised because of difference in formats of path name between Win32 and UNIX.

Local CGIs

Local CGIs in $LIB (/usr/local/lib/w3m/cgi-bin by default) use /usr/bin/perl.
If you want to use ActivePerl (a native application) and so on, please modify
the each scripts in $LIB with wrapper scripts as follows:

------ /usr/local/bin/winperl ------
#!/bin/sh
# wrapper script for Win32 Native Perl
PERL=/cygdrive/c/Perl/bin/perl.exe
case $1 in
  -*)
    ;;
  *)
    SCRIPT=`cygpath -w $1`
    shift
    ;;
esac
exec "$PERL" "$SCRIPT" $@
------------------------------------

Where the PERL= is the path of Native Perl in Cygwin context. cygpath
utilities come with Cygwin packages.

For directory listing, when "Use external program for directory listing" is
set "NO", you can browse the directory list without local CGIs.

Editors

w3m uses external editors to operate texts textareas and so on. You can use
any native application as the external editor with the script as below:

------ /usr/local/lib/w3m/winedit ------
#!/bin/sh
EDITOR='/cygdrive/c/Program Files/sakura/sakura.exe'
FILE=`cygpath -a -w $1`
exec "$EDITOR" "$FILE"
----------------------------------------

Where the EDITOR= is the path of Native Perl in Cygwin context.

If you use inetd as a service in WinWinNT and connect to localhost by telnet,
the windows will be opened only if "デスクトップとの対話をサービスに許可" is
ON.

Known Bugs

LF is converted to CR+LF when use -dump or -dump-source options.
    Make sure USE_BINMODE_STREAM was defined in compilation. Try to
    re-configure and make, or set binmode to the environment variable CYGWIN.
Can't input through IME in DOS prompt of Win9x.
    When "tty" is included in the environment variable CYGWIN, it is not
    permitted to avoid problems in tty layer of Cygwin. Remove "tty" from
    CYGWIN.
Cursor keys doesn't work when IME is ON in DOS prompt of Win9x.
    This is the problem of DOS prompt of Win9x and tty layer of Cygwin. Use
    C-f, C-b, C-p, and C-n instead.
Screen is not controled correctly in command prompt of WinNT.
    Set the each size of screen buffer and window in a same value, and/or
    disable the back scrolling.
Can't use the mouse with DOS prompt or command prompt.
    When "簡易編集モード" is ON, mouse events are not handed to w3m. Set it
    OFF.
Mouse buttons behave funny with DOS prompt or command prompt.
    In cygwin-1.3.15 or earlier, the escape sequence of the right and center
    button of the mouse are inverted. It is fixed in cygwin-1.3.16-1. Please
    make w3m in the environment you use, because w3m can't judge the versions
    of Cygwin perfectly,

Others

In Cygwin environment, it should be confortable to use not DOS prompt or
command prompt but telnet clients like TeraTerm, PuTTY, and so on with inetd
in localhost, or other tools as rxvt or cygterm.
