You can select a few of Markup Shredders settings if you press [S] and one of the keys mentioned in the following sub-sections.
To edit any item, press [Enter] to jump into the input line, and the [Up] or [Down] arrow key to leave it. Typing [Backspace] removes undesired characters. Press [Q] to quit the selection dialog.
All changes that you have done here are assigned to variables like
[GMS_CODEPAGE] in $GMS_ROOT/etc/gerolf (Linux)
respectively %GMS_ROOT%\etc\ gerolf.bat (Dos, Windows), the launcher and configuration script.
[A]: The menu animation can be switched on or (nearly) off.
GMS makes use of the reply binary, which draws a menu box line after line. GMS
provides a fast drawing mode and another one that looks a bit nicer. The effect
is nearly invisible on modern computers, but on a slow Dos machine, menu building may last too long; so the command
line interface should be used instead.
[C]: You
can set the interface colors as you like. GMS will open
a color pane and another input box where you can enter numbers between
0 (black) and 15 (white) for the foreground colors
(text, hotkey, and pattern). The numbers for background colors (banner, shadow,
and desktop) must be in range 0 to 7 (gray). The
desktop pattern letter is defined by its index number in the US-American code
page (ASCII); it must be in range 32 (blank) to 126
(tilde).
By default, all these values are set to R, meaning that they
are assigned a random number after every viewer call or execution of
external programs (chameleon mode). If you want to set the interface to
fixed colors, try the following numbers: 15, 15,
15, 2, 4, 1,
47, or 0, 12, 15,
7, 0, 1, 92.
[P]: GMS opens another input
box where you can enter the name of the program
binaries to be associated with the main GMS menu functions (view, edit, browse, analyse, typeset, and read). These executables – or
startup shell scripts, batch files, links (*.sh,
*.bat, *.lnk) – should be found in the
search path or in [GMS_BINARIES], a sub-directory
of [GMS_ROOT]/bin. Do
not enter paths, spaces and parameters into the input line, only the file
name is allowed.
For example, if you want to use HTML-Kit (Windows NT/XP) as
editor to be called from GMS, open Explorer, change into the
%ProgramFiles%\Chami\HTML-Kit\bin directory
and click on HTML-Kit.exe with the right mouse button. In the
context menu select create link. Move this link to
%GMS_ROOT%\bin\win and rename it to HTML-Kit;
so the corresponding link file is named HTML-Kit.lnk.
Enter HTML-Kit.lnk into the editor input line in the
program selection dialog. Do not add a search path or a parameter
here.
On Windows 9x, LNK files are not
executable; so in %GMS_ROOT%\bin\win, create a
HTML-Kit.bat batch file instead, consisting of just the line "%ProgramFiles%\Chami\HTML-Kit\bin\HTML-Kit.exe"
%1 %2 %3 %4
%5.
On Dos, omit the quotation marks when calling a
program from a batch file. To access your work file, you can also make use of
the variables %GMS_REMODRV% (drive letter),
%GMS_FOLDER%, %GMS_FILE%,
%GMS_SHORT% (8.3-format) and
%GMS_BASE% (no extension). – Similarly, on Linux, use $GMS_FOLDER,
$GMS_FILE and $GMS_BASE.s
[D]: If you want to engage in
debugging Markup Shredder, you can set this item to
other values than 0 (no debugging): Z creates
a [GMS_ROOT]/etc/gmsdebug.log file, listing all internal calls to the
command line and text mode interface modules, together with
parameters and values of important environment variables (not on
Dos and Windows 9x).
X traces these module calls on additional banners inside the
text mode interface. Y does the same in
slow motion.
[E]: Here you can enter the
main 8-bit encoding, which fits for most of the
fonts used with Markup Shredder, usually one of a Latin alphabet. Encodings
that cover only a small number of fonts should be defined in the GMS
configuration files font.cfg, encoding.cfg and alias.cfg in
[GMS_ROOT]/etc.
Every letter in a HTML file is stored as a number indicating its index in a
table of characters. Since every code page can only hold
28 = 256 characters, there are systems of
related code pages covering a wider range: First, the iso-8859-x or
i8859-x series by ISO. Second, the
windows-125x or cp125x series by Microsoft, which
makes a more efficient use of the table space. Third, the Unicode system that defines hundreds of consecutive code
pages to enumerate every character of every language on earth. But there are
also code pages that have been developed independently to fit a particular
language or script, for example ISCII (Indian) or VISCII (Vietnamese).
Markup Shredder will employ a matching code page designation, if you
simply enter one of the following keywords: Arabic,
Baltic, Central, Cyrillic,
Greek, Hebrew, Indian,
Latin, Thai, Turkish,
Vietnamese, or Western.
You cannot enter the word Unicode (or UTF-8) here.
Markup Shredder works with 8-bit input files, and you have to decide for one
single code page, not a whole series. However, GMS gives you access to fonts
with a different encoding, if Unicode characters are escaped according to
the HTML specification, writing the mathematical infinity symbol
∞ as ∞ or
∞, for example. You can change a file’s encoding
with your browser’s menu function File/Save as.
Whenever you have changed the standard code page here, you still must re-compute the TeX font metrics (in order to write the font map) and re-initialize the TeX format file for GMS.
In the text mode interface, Markup Shredder can only show half of the characters from the current code page.
cp125x series, Markup
Shredder can change the terminal font code page accordingly.7 bit code page defined around the year 1960 that only covers the
characters of an American typewriter. Table positions 0 to
31 and 127 are reserved for functions like bell,
carriage return, line feed or paper feed. If characters are displayed on these
positions, then they are system-dependent. Most code pages –
but not the Unicode pages beyond the first – are based on ASCII,
using the upper half for non-English characters.Enter gms -s to open the
