<section*|General>
<\question>
<label|general-1>\<#4EC0\>\<#4E48\>\<#662F\><TeXmacs>?
</question>
<\answer>
GNU <TeXmacs>\<#662F\>
<\itemize-dot>
<item>is a free scientific text editor, which was both inspired by
<TeX> and GNU Emacs.
<item>allows you to write structured documents via a wysiwyg
(what-you-see-is-what-you-get) and user friendly interface.
<item>lets you create new styles.
<item>implements high-quality typesetting algorithms and <TeX> fonts,
which helps you to produce professionally looking documents.
<item>is suitable as an interface for computer algebra systems, as the
high typesetting quality goes through for automatically generated
formulas.
<item>can be highly customized as it supports the
<name|Guile>/<name|Scheme> extension language.
<item>lets you export your documents to PS and PDF and offers both
import and export to HTML, <LaTeX>, Scheme, Verbatim and Xml. We would
very much appreciate your <hlink|help|http://www.texmacs.org/Web/Contribute.html>
for writing and improving converters for <TeXmacs> documents.
</itemize-dot>
</answer>
<\question>
<label|general-2>For what typical purposes do people use <TeXmacs>?
</question>
<\answer>
<TeXmacs> can be used for
<\itemize>
<item>Books and Articles. They can be written fully within <TeXmacs>.
If your publisher requires a certain <LaTeX> style for an article, then
as a last step you can export your document to <LaTeX> and make the
final modifications there.
<item>Presentations.
<item>Interface to computer algebra systems and other scientific
software.
<item>Webpages. For example the <TeXmacs> webpage is maintained as
<TeXmacs> documents, which are exported to <name|Html>.
</itemize>
</answer>
<\question>
<label|general-3>What Operation Systems are supported?
</question>
<\answer>
<TeXmacs> can be easily installed on all major systems, such as
GNU/<name|Linux>, <name|MacOS> and <name|Windows>. There are <name|rpm>
and Debian packages as well as binaries available for <name|Linux>. For
Mac <name|OS X> there is a <name|Fink> package. For <name|MS Windows>, a
<name|Cygwin> package is available.\
</answer>
<\question>
<label|general-4>What are the system requirements?
</question>
<answer|A reasonably fast machine is recommended. Having said this, I
(Andreas) am typing this on a Pentium III 450Mhz under Cygwin, and
<TeXmacs> is still useable here, although not overly reactive.>
<\question>
<label|general-5>I have already learned <TeX>/<LaTeX> and <name|Emacs>,
do I have to learn all over again?
</question>
<answer|You will find out, that much <LaTeX>-knowledge can be reused. For
example, you can start a section by typing <key|\\section[return]> or you
get <math|\<alpha\><rsub|1>> by typing <key|$\\alpha_1$>. Note that there
are even shorter ways provided, for example <key|$a[tab]$> gives you an
alpha as well, so you might want to migrate after a while. Styles like
article, book or seminar, as known from <LaTeX>, are provided as well.
Furthermore, many <name|Emacs> shortcuts like <key|C-x C-s> for saving a
file, or <key|C-_> for undo will work. >
<\question>
<label|general-6>I have a question, where should I ask it?
</question>
<answer|The best place is the <TeXmacs> user mailing list. Search this list
and the FAQ beforehand, to ensure your question was not asked before.>
<\question>
<label|general-7>Is it free Software?
</question>
<answer|<TeXmacs> falls under the GNU public licence. >
<section*|System Appearance and Behavior>
<\question>
<label|sys-2>How can I see the <LaTeX> or <TeX> code corresponding to
what I see on the screen?
</question>
<answer|This question is due to a fundamental misunderstanding about
<TeXmacs>. Indeed, <TeXmacs> is not <em|based> on <TeX>/<LaTeX>, although
it does support (not yet perfect) <em|conversion> to and from <LaTeX>.
Furthermore, in theory at least, there is actually no need anymore to look
at something like the <TeX> source, since <TeXmacs> is guaranteed to be
fully WYSIWYG. Conversion to <LaTeX> may only be useful, when transmitting
an accepted paper to the publisher of a journal.>
<\question>
<label|sys-4>Trying to start <TeXmacs> remotely over a ssh connection, I
get an error, while <abbr|e.g.> xclock works without a problem?
</question>
<\answer>
If you get an error message including the following:
<verbatim|Fatal error: I failed to connect to Xserver in
'x_display_rep::x_display_rep>
then execute <verbatim|export DISPLAY=127.0.0.1:10.0> on the remote
machine and make sure your /etc/hosts file is sound, <abbr|i.e.> it
contains the line <verbatim|127.0.0.1 localhost> and the IP information
about the local and remote machine.
</answer>
<\question>
<label|sys-5><TeXmacs> is unusually slow while editing?
</question>
<\answer>
Graphics card drivers with poor 2D performance can slow <TeXmacs> down
tremendously.\
If you are running TeXmacs under X on a system with an ATI graphics card
and are using ATI's proprietary drivers (the driver called
<verbatim|fglrx)>, you can achieve a significant speedup by
<\itemize>
<item><em|either> running an X server such as Xgl that performs 2D
operations using the 3D API of the graphics card driver,
<item><em|or> switching to an open source graphics card driver such as
<verbatim|ati> or <verbatim|radeon> which have a far better 2D
performance than <verbatim|fglrx>.
</itemize>
Note that if you try both at the same time, you will slow your system
down even more, instead of speeding it up.
</answer>
<section*|Windows and Cygwin specific>
<\question>
<label|cygwin-4>My Windows username contains spaces. Will this cause
problems?
</question>
<answer|It is strongly recommended to have a Windows username without
spaces. Please make a new account, as simply changing the username could be
insufficient.>
<\question>
<label|cygwin-1>What to do with Cygwin specific questions?
</question>
<\answer>
Look at the Cygwin FAQ at <hlink|http://cygwin.com/faq.html|http://cygwin.com/faq.html>,
the Cygwin User Guide at <hlink|http://cygwin.com/cygwin-ug-net/|http://cygwin.com/cygwin-ug-net/>
and search the Cygwin mailing list <hlink|http://www.cygwin.com/ml/cygwin/|http://www.cygwin.com/ml/cygwin/>.
</answer>
<\question>
<label|cygwin-2>How to associate .tm files with <TeXmacs> inside Cygwin?
</question>
<\answer>
Create a file <verbatim|texmacs.bat> with the following content:
<\verbatim>
\ \ \ \ rem cmdow @ /hid<next-line> \ \ \ c:\\cygwin\\bin\\bash --login
-c "texmacs \\"`cygpath -u "%1"`\\""
</verbatim>
Ensure that it lies in your <verbatim|PATH>. Now you can associate .tm
files with this batch file.
If you want to hide the black Cygwin window when <TeXmacs> is started,
then download <name|cmdow> from <simple-link|http://www.commandline.co.uk/cmdow/>,
drop <verbatim|cmdow.exe> <abbr|e.g.> in your
<verbatim|C:\\WINDOWS\\system32> directory (this applies to <name|Windows
XP> installed on <verbatim|C:\\>) and uncomment (<abbr|i.e.> remove
``rem'' from) the first line of <verbatim|texmacs.bat>.
</answer>
<\question>
<label|cygwin-3>How to get spell checking working inside Cygwin?
</question>
<\answer>
Install the Cygwin package aspell. Execute in a shell:
<\verbatim>
\ \ \ \ cd /usr/bin<next-line> \ \ \ ln -s /usr/share/aspell/ispell
ispell
</verbatim>
</answer>
<section*|Usage>
<\question>
<label|usage-1>How to mark/select a whole paragraph?
</question>
<answer|Clicking once on a word will place the cursor there, clicking twice
marks this word, clicking thrice will mark the paragraph and so on;
eventually, the whole document will be selected.>
<\question>
<label|usage-2>Spell checking always starts at the beginning of the
document?
</question>
<answer|Mark a region, and spell checking will be restricted to this
selection.>
<\question>
<label|usage-3>How can I insert an OpenOffice.org table?
</question>
<\answer>
\;
<\enumerate>
<item>Create a PostScript image of your table using OpenOffice
(<samp|File<math|\<rightarrow\>>Print<math|\<rightarrow\>>Print to
file)>. Name the file, for example, ``<kbd|table1.ps>''.
<item>Convert the PostScript file to an Encapsulated PostScript file
(<verbatim|.eps>) using <verbatim|ps2epsi> in a shell. Just type:
``<kbd|ps2epsi table1.ps table1.eps>''.
<item>Insert or link the image <verbatim|table.eps> in the <TeXmacs>
document.
</enumerate>
</answer>
<\question>
<label|usage-4>How can I insert the number of pages?
</question>
<answer|Put a label on the last page of your document and use the
<verbatim|pageref> primitive in order to produce the corresponding number.>
<\question>
<label|usage-5>How can I resize an image?
</question>
<\answer>
Put your cursor right behind the image and edit the fields in the lowest
icon bar. You may for instance set the width to <verbatim|5cm> and the
height to <verbatim|27mm>. When leaving the width open, it will
automatically be determined as a function of the height (and vice versa).
When leaving both fields open, the image will be reproduced at its
original size. Notice that a width of <verbatim|1par> will span your
image over the paragraph width. The remaining two fields specify the
<math|x>-offset and <math|y>-offset of the image. By default, images are
aligned at the bottom. When specifying <verbatim|-0.5h> for the last
field, the image will be vertically aligned at the center.
</answer>
<section*|Microtypography>
<\question>
<label|typo-1>There is too much space after an abbreviation like
<abbr|wrt.> or <abbr|etc.>?
</question>
<answer|This is because <TeXmacs> thinks, that the sentence ends after the
dot in the abbreviation. To resolve this <em|a posteriori>, mark the
abbreviation and press <shortcut|(make 'abbr)>. To care for this while
writing: <shortcut|(make 'abbr)><key*|e t c . right>.>
<\question>
<label|typo-2>How to add unbreakable space?
</question>
<answer|Type <shortcut|(make 'no-break)> after the space.>
<section*|Remaining legacy questions>
<\question>
<label|legacy-1>A publisher sent me a giant <LaTeX> preamble I'm supposed
to put in in order to prepare a book for them. What is the best way of
putting it in and figuring if it will work?
</question>
<\answer>
I recommend to convert the preamble to <TeXmacs> and to put the result in
a <TeXmacs> style file. However, the result will probably be
disappointing, because conversion between <TeX>/<LaTeX> and <TeXmacs> is
not yet perfect and style files are particularly problematic. What you
can also do is write a <TeXmacs> style file by your own which supports
the major extra constructs you want to use from the editors style file.
When you convert your book to <LaTeX>, you next use the editors style.
Some layout will probably need to be redone at that stage, but this
should actually be the work of the editor... Please look in the <TeXmacs>
help for more information about conversions between <TeXmacs> and
<LaTeX>.
