Hi,

do you have some beamer style file to show me ? My point is : with
latex, when you compile your beamer.tex file you have some icons on
tyhe right or on the bottom of the page. Do we get this with Texmacs ?

Thank you.

Hi Marc:

Attached is a TeXmacs file as an example in the "beamer" style. Also attached is an exported PDF file produced using TeXmacs that is also of the "presentation" style. This file is an article I wrote that summarizes the issues I encountered involving using TeXmacs for creating presentations. It also covers some general presentation technical issues.

Note that it does not appear possible to export a TeXmacs presentation in "beamer" style to PDF from TeXmacs. Each slide has to be individually exported then merged outside of TeXmacs using Adobe Acrobat or some other utility for that purpose. From my point of view the "beamer" style appears to be concatenated TeXmacs pages in the form of slides. These pages behave as independent documents in some ways, but contained as one file.

The TeXmacs "beamer" style has some really nice features and works well if you are in an environment either where you use TeXmacs as a main tool, or are involved in a group where TeXmacs is the format of choice. Otherwise portability may become an issue. I found that using TeXmacs to create presentations with the goal of PDF as a end format provides the best of both worlds.

I encourage any comments or feedback on the attachments. Please note that the content of the Texmacs beamer file was not well-formatted for presentations because I did not have the time. Hence, some slides are vertically too long. You would want to split this content into more pages in an actual presentation. So for those that are annoyed by this, I am aware of this defect.

Hope this helps.

<section|What <TeXmacs> Does Well>

\;

<TeXmacs> is a comprehensive tool for producing documents to be
printed, exported (e.g., <abbr|PDF>, HTML, etc.), or used as
presentations. In this sense, it is not different than many other
general and specialized programs used for these purposes. However,
for users that need a program oriented toward the production of
certain types of technical documentation, <TeXmacs> is an excellent
choice. Users that might otherwise use <LaTeX> for producing
documents with significant mathematical content and technical
graphics should find <TeXmacs> a convenient and time-saving tool.
Those new to <LaTeX> may find <TeXmacs> to be considerably easier in
terms of learning a new system. Unless specialized or unique
capabilities are required, <TeXmacs> should meet the needs of those
authoring technical documents containing mathematical expressions and
graphics. Using existing plug-ins, <TeXmacs> extends its built-in
features as a flexible and powerful interface to external open-source
and commercial software, including so-called computer algebra systems
for symbolic manipulation of expressions and software for processing
expressions numerically.
</hidden>|<\hidden>
<section|First Steps>

This document assumes that the reader has the familiarity of a
beginner with the <TeXmacs> user interface and with the notion of
modes, focus (cyan box), and text selection (red box) using the mouse
or cursor keys <emdash> <key|down>, <key|up>, <key|left>,
<key|right>. If this sounds unfamiliar, refer to the
<menu|Help|Manual> menu item drop-down list of sections.

The following are some first steps relevant to most <TeXmacs>
documents:

<\itemize-dot>
<item>Use the <menu|Edit|Preferences|Look and feel> menu item to
set the preference for the ways the <TeXmacs> user interface
appears. This setting also affects some behaviors automatically.
<TeXmacs> attempts to detect the most relevant setting based on the
system being used. If this is not the case, then select the
operating system or desktop environment that most closely matches
the system being used. If you don't know what <name|Emacs> is, then
don't select this setting. If you know what <name|Emacs> is, and
you prefer an <name|Emacs> look, feel, and behavior, then this may
be a good choice.

<item>Use the <menu|Edit|Preferences|Interactive questions> menu
item to specify how prompts will be displayed for required user
input. Questions may either be displayed in separate windows or in
the status bar area of the <TeXmacs> interface. The separate window
input method is the most obvious to the user and, more likely than
not, the most familiar. It is easy to not notice interactive
questions displayed using the status bar for those new to
<TeXmacs>.

<item>Use the <menu|Edit|Preferences|Simplified menus> menu item to
specify the level of selections displayed in the menus. The less
frequently used features will be not be displayed in in the menus
by selecting <menu|Simplified menus>. This makes matters easier at
first. This setting can be changed later after the user has more
experience with <TeXmacs>.<page-break>

<item>If you intend to use a physical printer device to produce a
paper copy of a document use the <menu|Edit|Preferences|Printer>
menu item to set various options related to printers and printing.
If the document is intended for export, such as <abbr|<abbr|PDF>>,
then not all the printer settings are relevant. In any case it is a
good idea to set the <menu|Paper type> for various reasons.

<item>Use the <menu|Edit|Preferences|Autosave> menu selection to
specify the time interval used for documentsto be ``auto saved.''
Edits to a document will be lost on any termination of <TeXmacs>
for any reason if the document file is not saved after edits are
made. This function limits lost work in terms of changes to
documents to no more than those made since the last auto-save time.
For the brave, auto save can be disabled.

<item>Select an overall document type or style. Use the
<menu|Document|Style> menu item drop-down list. This determines the
way in which other content is styled as well as the overall style
of the document.

<item><TeXmacs> will display informative ``flags'' that by default
are not printed that serve to provide useful information of various
kinds at points within a document. Some find these informative
flags useful, and some may find them distracting. \ Use the
<menu|Document|View|Informative flags> menu selection to select how
informative flags are displayed.

<item>It may be useful to view the document as it will appear on
paper. Use the <menu|Document|View|Page layout|Margins as on paper>
menu selection for this purpose. There also is a selection named
<menu|Show header and footer> which displays what it says. These
options merely affect what the user sees and not what is printed or
exported. to be ``auto saved.'' Edits to a document will be lost on

</itemize-dot>

The above customizations and settings are not comprehensive. However,
these should be adequate for most users for getting started with
<TeXmacs>. There are many ways to customize or extend <TeXmacs>
including defining individual style files, customizing the user
interface, or linking to external programs. See the <TeXmacs>
<name|Help> documentation sections related to plug-ins, customizing
the interface, and modifying existing styles or creating new styles.
However, these may be termed ``advanced'' topics. So unless there is
a pressing specific need, the best approach is to become familiar
with the basics and essentials of <TeXmacs> prior to becoming
immersed in advanced technical details and features.<page-break>
</hidden>|<\hidden>
<section|Content Tags>

\;

Content tags affect how selected or typed text appears. Use content
tags to modify the default appearance of text. From the
<samp|Insert><math|\<rightarrow\>><samp|Content tag><math|> menu
drop-down list, the following are examples of the style of common
Content tags:

\;

<\itemize-dot>
<item>Emphasis <emdash> This cannot be <em|emphasized> enough.

<item>Strong <emdash> What makes this <strong|strong>?

<item>Name <emdash> <name|Linux> is the name of an operating
system.

<item>Person <emdash> <person|John Smith> is the name of a person.

<item>Definition <emdash> True by this <dfn|definition>.

<item>Sample <emdash> A sequence of <samp|literal> characters.

<item>Abbreviation <emdash> F.M.A. is an abbreviation for Federal
Management Annunciators

<item>Acronym <emdash> <acronym|RADAR> is an acronym for radio
ranging and receiving.

<item>Verbatim <emdash> <verbatim|verbatim text looks like
typewriter output. What is a typewriter?>

<item>Keyboard <emdash> <kbd|keyboard is used to indicate what is
entered by keyboard.>\

<item>Code <emdash> <code*|Code is for computer language source,
etc.>

<item>Variable <emdash> indicates a <var|variable>. Thus, <var|x,
y, and z> are variables: <kbd|cp> <var|this-file that-file>

<item>Cite <emdash> A reference to book or magazine, etc.
Melville's <cite*|Moby Dick>.
</itemize-dot>

It is important to keep in mind that while some of these content tags
produce the same result as displayed here, this might not be the case
if the overall document style is changed or modified. So it is not a
good idea to use one of these tags for this reason. In other words,
in spite of this apparent redundancy, tag the document text for what
it is.
</hidden>|<\hidden>
<section|Prominent Text>

Prominent text also affects how text appears, but the difference is
the intended categories of text and the extent of the content.
Prominent text is intended to affect the style of the categories of
text as listed below:

<subsection|Quotes>

<\quote-env>
<with|color|blue|This text is styled as a <strong|quote>. The blue
color is not part of the style. Change the color of text using the
palette of colors displayed by the <menu|Format|Color> menu
selection. It was added for emphasis. Quotes may be rather long.
The format is all that changes here. To <strong|quote> means to
repeat the <em|exact words> of another with the acknowledgment of
the source or person. The <em|quote> of the example below has been
``fancied up'' with some font style and an <em|em dash>.>
</quote-env>

<\example*>
Of a quote.
</example*>

<\quote-env>
<with|color|blue|<\with|font-shape|italic>

\;

<\with|par-mode|right>
<\with|par-mode|center>
<emdash> <with|font-shape|slanted|Confucius>
</with>
</with>
</with>>
</quote-env>
</hidden>|<\hidden>
<subsection|Quotations>

<\quotation>
<with|color|blue|This is a <strong|quotation>. This is indented
unlike the quote above. Otherwise they look the same. However, A
<strong|quotation> is a phrase or a sentence from a book or a
speech that reflects the author's ``profound'' thoughts. You will
probably want to cite a quotation.>

<with|color|blue|``This difference alone is a profound
thought.''[Miller2012]>

<with|color|blue|As I see it. You might not use quotation marks
here. Not sure.>
</quotation>

Often the words <strong|quote> and <strong|quotation> are used as
substitutes for each other. ``<name|Quote>'' is a <em|verb> and
``<name|quotation>'' is a <em|noun>. So, in effect, you <em|quote> a
<em|quotation> when these words are used in this way.

<\quotation>
<with|color|blue|<\em>
Despite that, using quote instead of quotation is so prevalent
that it is sometimes considered acceptable. So, you will find
terms like: love quotes, inspiration quotes, funny quotes...
</em>>
</quotation>

instead of <em|love quotations>, <em|inspirational quotations>,
<em|funny quotations>, etc.

Is this quotation that I have quoted a profound thought? In any case,
these terms can be confusing.

<\note*>
In deference to this popular usage, the Quotations site on
<samp|About.com> uses these words interchangeably.

<subsection|White space <emdash> Lines and Spacing>

Don't get too creative about the general formatting of the document
by using blank lines and \ \ \ \ s \ p \ a \ c \ e \ s \ \ as white
space. Use the the formatting capabilities of <TeXmacs> instead. This
kind of stuff that you throw in there can cause issues with the
layout depending on the circumstances. Refer to the <TeXmacs>
documentation for information related to content styles, settings,
and customizations that affect spacing.

<section|Lists><person|>

<TeXmacs> comes equipped with all the list types that should ever be
needed. The list examples below demonstrate what is available:

<\itemize-dot>
<item>Bulleted list item.

<item>2nd item.

continued... use <key|Shift+Enter> key sequence to continue lines
below a list item.\

a continued line can merely be more text or used to start a sub
list.

more continued..

<item>3rd item.
</itemize-dot>

<\enumerate-numeric>
<item>Numbered item <emdash> use the <key|Shift+Enter> key sequence
to continue lines and start a different list item type below:

<\enumerate-roman>
<item>A different numbered item type as a sub list. A different
``number'' style <emdash> lower case Roman numerals which the
Romans would not recognize as such.

<item>The second item in this sub list <key|Enter>
</enumerate-roman>

<item>Back to the ``parent'' numbered list (by pressing <key|Enter>
at the <strong|end><\footnote>
The word ``end'' used here is related to the <em|focus> <emdash>
the <em|cyan-colored> selection box. Pressing the <key|Enter> key
at the ``end'' of a line of a list will continue to add items to
this same list level. Pressing the <key|Enter> key with the
entire list level in focus adds a new list item of the type of
the ``parent'' list. This is an example of a footnote. These are
automatically inserted and numbered. The type of numbering used
depends on the document <em|style> selected and the customized
<em|packages> being used. The style of this document is an
<verbatim|article>.This style may be used for writing short
scientific articles, which are subdivided into sections. The
numbering of environments like theorems, remarks, etc. is
relative to the entire document. Packages are used for
customizing the behavior of the standard styles For example, If
you use the <verbatim|number-long-article package>, then the
numbers are prefixed by the section number. In this case, this
footnote would be numbered 5.1 instead of 1. The
<verbatim|number-uspackage> may be used in order to switch to
American style numbering in the case when style file enforces
European or some other style of numbering. Customized numbering
is determined by the packages that are added or removed using
<menu|Document|Add Package|Customize> and <menu|Document|Remove
Package|Customize> menu selections. See the <TeXmacs> <menu|Help>
menu selections for information concerning packages and
customizations.

<section|Hybrid <LaTeX>/<TeXmacs> Command Mode>

<TeXmacs> allows you to enter <LaTeX> commands directly from the
keyboard. Press the <key|\\>-key in order to display
<inactive|<hybrid|>> and enter the <em|hybrid> <LaTeX>/<TeXmacs>
command mode. Next type the desired command name within the blue
brackets at the position of the cursor after the backslash. The left
footer area displays something like

<\verbatim>
\ \ \ \ \<less\>Return\<gtr\>: an action to be performed (e.g.,
activate symbol or macro)
</verbatim>

Press the <key|Enter>-key (or <shortcut|(kbd-return)>-key) and the
command will be executed.

<\note*>
To insert a literal <kbd|\\> (backslash) character, use the
<key|symbol \\> key sequence. The same for a $ character. Use the
key sequence <key|Shift+F5|><key|Shift+$> to insert a $. This is
necessary due to the fact that these characters have special
<TeXmacs> functions that override the usual character that is
expected to be displayed. In the case of the $ for example, it is
used to enter \ ``math mode'' and so is not displayed.
</note*>

<\example*>
Enter a math mode fraction expression as: <inactive|<hybrid|frac>>
<key|Enter>. The result is <frac|n|d> where <verbatim|n> and
<verbatim|d> have been entered from the keyboard in the resulting
<em|cyan> entry box above and below using the
<math|<key|\<uparrow\>>> and <math|<key|\<downarrow\>>> keys.
</example*>

<TeXmacs> allows entry of many of its commands and not only <LaTeX>
commands directly from the keyboard. To do this enter a backslash
character the same way as above (as <kbd|<verbatim|<kbd|\\>)>> and
<verbatim|<inactive|<hybrid|>>> \ appears with the cursor positioned
after the <verbatim|\\>. For example, to enter an <em|em dash>
\ (<emdash>) character type <inactive|<hybrid|emdash>><kbd|> and the
<key|Enter> \ (or <key|Return>) key. If the entry is recognized as a
<LaTeX> command then the expected result should follow. Otherwise a
<TeXmacs> command may be recognized.

If not then nothing useful results, as in <badcommand>, then this is
merely displayed for example since <kbd|badcommand> is literally the
entry made that was not recognized. So what is displayed in the
brackets is literally what was entered that was not recognized in any
case. For example the styled text <TeXmacs> and <LaTeX> are displayed
here as shown using this technique. The required entries are
<inactive|<hybrid|TeXmacs>><kbd|> and <kbd|<inactive|<hybrid|LaTeX>>>
respectively, then the <key|Enter> \ (or <key|Return>) key in both
cases . However, <tExMACS> or <laTeX> won't work. They are ``bad
commands'' in this context. There are numerous <TeXmacs> commands

See the subsection of <TeXmacs> help titled <name|Hybrid commands and
<LaTeX> simulation> for a description of entering hybrid commands.
</hidden>|<\hidden>
<section|Enunciations>

The following are examples using <em|enunciations> (also known as
<em|environments>). Some of these are numbered automatically and some
are not. These instances below use the so-called European style of
numbering. This can be had by selecting <menu|Document|Add
package|Customize|number-europe>. This is an example of how packages
may influence the overall style. These are also customized using
<menu|Document|Add package|Customize|number-long-article> package.
This package prefixes section numbers. Another package option that
can be used that affects numbering style is <menu|number-us>. Using a
package for this purpose merely <em|customizes> the document style
selected from the <menu|Document|Style> menu. Select these
enunciations using the <menu|Insert|Enunciation> menu drop-down list.

<\note*>
The examples are colored <with|color|blue|blue> for emphasis. The
default is black text.
</note*>

<\subsection>
\;

Theorems
</subsection>

\;

There are several different ways to present theorems.

<\example>
The ``standard'' way:
</example>

<with|color|blue|<\theorem>
The standard theorem.

\;

Everything goes in here related to the proposition and proof of the
theorem.

<\proof>
This is where the proposition is proved.
</proof>
</theorem>>

<\example>
Enter a backslash after the theorem number to display
<inactive|<hybrid|>>. Type <with|color|dark
green|<em|<samp|dueto>>> after the backslash. Press <key|Tab> after
<with|color|dark green|<em|<samp|dueto>>> to get a \| character so
that <verbatim|Euler> can be entered in the brackets after the \|
character. Then press the <key|Enter> \ (or <key|Return>) key.
</example>

<with|color|blue|<\theorem>
<dueto|Euler>This famous result is shown below:

<\equation*>
e<rsup|i\<pi\>> \<noplus\>\<noplus\>+ 1=0
</equation*>

<\proof>
Refer to the appendix.
</proof>
</theorem>>

<\example>
Another way using <inactive|<hybrid|dueto>>,

<samp|Insert><math|\<rightarrow\>><samp|Prominent><math|\<rightarrow\>><samp|Framed>
and a named theorem with a proposition to state the theorem instead
of using the space after the theorem number for this purpose.
</example>

<with|color|blue|<\framed>
<\theorem>
<dueto|Socrates>The Kind of Life Not Worth Living Theorem

<\proposition*>
The unexamined life is not worth living.
</proposition*>

<\proof>
Still working on this part.
</proof>
</theorem>
</framed>>

<\note*>
Environments (or Enunciations) such as theorems, propositions, etc.
are automatically numbered by <TeXmacs> with few exceptions. This
default numbering behavior can be circumvented for particular cases
by entering a backslash character which results in the following
prompt being displayed <inactive|<hybrid|>> with the cursor
positioned after the backslash. Entering, for example,
\ <kbd|proposition*> after the backslash displays
<inactive|<hybrid|proposition*>>. Pressing the <key|Enter> \ (or
<key|Return>) key with the cursor after the asterisk results in
rendering without the automatic number. This is the method used in
this example to prevent the proposition from being numbered. This
is also how this unnumbered note was displayed <emdash>
<inactive|<hybrid|note*>>. Numbering can also be manipulated in
other ways. See The standard <TeXmacs> styles section in the
<name|Help Reference Guide>, for information concerning counters
and counter groups.

<section|Mathematical Expressions>

Use <samp|Edit><math|\<rightarrow\>><samp|Paste
from><math|\<rightarrow\> ><samp|LaTeX> to paste copied <LaTeX> code
directly into document. Where this copied <LaTeX> code comes from is
up to the user. Mostly, the results are as expected, but not always.
Use this feature only if there does not appear to be a way to enter
the mathematical expressions using the built-in features of
<TeXmacs>. There are three ways to create mathematical expressions
(called formulas in the Help documentation) using the built-in
features of <TeXmacs>. While the words ``formula'' and ``equation''
are often used in this context, it is better to interpret this merely
as meaning any mathematical expression. These are summarized below:

<\itemize-dot>
<item>An <em|inline> expression: <math|lim <rsub|n \<to\>
\<infty\>> x<rsub|n>>. This limit expression style works better
inline. Use <menu|Insert|Mathematics|Formula> or <key|$> key for
inline expressions.

<item>A <em|displayed> (<em|equation>) expression. Formats
expression as a centered individual paragraph. Use
<menu|Insert|Mathematics|Equation> or <key|Alt+$> \ key sequence.\

<\equation>
<below|lim|x\<rightarrow\>\<infty\>> \ x<rsub|n>
</equation>

<item>An <em|array> of expressions. These act like a table of three
columns. The relation or expression of the center column does not
have to be an equal (=) sign<\footnote>
The last expression shows that any relation (or expression)
between two expressions of the cells on the left and right of the
center cell may be used. In fact, the cells of this array type of
\ mathematical expressions may contain any expression content
including nothing if that is what is intended. So this feature
provides flexibility in terms of what is possible. This also
serves to demonstrate the insertion of another \ footnote. Use
the <menu|Format|Insertion|Footnote> menu item or \ the
<key|Ctrl+Shift+F> key sequence to enter footnote. Footnotes are
automatically numbered and the style of numbering is determined
by the document style as modified by any packages used that
affect numbering as described previously.
</footnote>. Columns or cells may be empty as required. Use
<menu|Insert|Mathematics|Equations> or <shortcut|(make-eqnarray*)>
key sequence. Use the the <key|Enter> \ (or <key|Return>) key with
the cursor in any row of the array to insert an empty row below the
cursor. When the focus is the array expression, lines appear that
outline the array rows and columns. The <key|Backspace> key will
delete the row that the cursor is in.

<\eqnarray*>
<tformat|<table|<row|<cell|<below|lim|x\<rightarrow\>\<infty\>>
\
x<rsub|n>>|<cell|=>|<cell|\<infty\>>>|<row|<cell|>|<cell|>|<cell|>>|<row|<cell|<big|sum>
<rsub|k=1><rsup|N>
k<rsup|2>>|<cell|=>|<cell|1<rsup|2>+2<rsup|<rsup|2>>+\<cdots\>+N<rsup|2><eq-number>>>|<row|<cell|>|<cell|>|<cell|>>|<row|<cell|<below|<above|<big|sum>|N>|k=1>

k<rsup|2>>|<cell|\<leq\>>|<cell|1<rsup|2>+2<rsup|<rsup|2>>+\<cdots\>+N<rsup|2>>>>>
</eqnarray*>
</itemize-dot>

Any of the above methods changes the entry mode to the <em|math
mode>. When in the math mode the focus is oriented toward math
expressions. The drop down selections of the <menu|Focus> menu item
as well as the focus toolbar reflect the math mode. The
<shortcut|(variant-circulate (focus-tree) #t)> key sequence switches
an expression between an inline formula and a displayed equation.
Make sure that the focus is the entire inline expression however,
otherwise the results may be applied to a sub-expression only.

Expressions such as the above may be numbered. You have to select
this though. The quickest way is to click on the IV (Roman numeral
icon) button of the focus bar in the math mode. Can also select
<menu|Focus|Numbered> from the menu drop-down list. The key sequence
<key|Ctrl+#> works also. The appearance of certain inline expressions
may be automatically applied in terms of vertical space. \ This can
be changed using <menu|Format|Display style|on>. Display style is
<em|off> by default.

The built-in <TeXmacs> methods and features of mathematical
expression entry are too numerous to be easily summarized. Refer the
the <TeXmacs> Help documentation manual section entitled
<name|Mathematical formulas> for details and a complete description.\

<section|Using <TeXmacs> as an Interface>

<TeXmacs> has a unique ability to communicate and interact with
external programs. In most cases this ``session'' with an external
``system'' typically occurs in shell-like sessions displayed as a
part of the <TeXmacs> document. Hence <TeXmacs> acts as a kind of
self-documenting command line interface where both user input and
external program output is displayed in a session mode of the
document. So in general, a supported session can be inserted and
displayed in the document the same way as other particular types of
content. This capability is provided by a <em|plug-in> that acts as
an interface between <TeXmacs> and the external program.

Each external program requires a plug-in for this purpose. Creating
these <TeXmacs> plug-ins requires specialized technical knowledge.
See the <TeXmacs> documentation for details. Fortunately a number of
plug-ins are already in existence. See <menu|Help|Plug-ins> for the
latest list of existing plug-ins installed with <TeXmacs> and more
documentation. See the <TeXmacs> website link

<hlink|http://www.texmacs.org/tmweb/plugins/plugins.en.html|http://www.texmacs.org/tmweb/plugins/plugins.en.html>
for a listing and description of some existing plug-ins.
</hidden>|<\hidden>
Below is a partial list of existing plug-ins<\footnote>
Note that the fact that a plug-in is listed for a program does not
necessarily mean that these are supported equally. These plug-ins
are typically the projects of individuals that have an interest in
the associated programs the plug-in is intended to accommodate.
These may or not be up to date and work with no issues. For
example, the <name|Maxima> plug-in appears to be functioning well
as of the date of this article. Unfortunately, the plug-in for
<name|Octave> does not appear to be without some issues not
described here. This is too bad, since <TeXmacs> as an interface to
<name|Maxima> and<name| Octave> is a highly desirable combination.
</footnote> as of the date of this document:

<item>Qcl

<item>R

<item>Sage

<item>TeXgraph

<item>Xfig

<item>Yacas
</enumerate-numeric>
</hidden>|<\hidden>
<\note*>
The <TeXmacs> website lists plug-ins only for external program
projects which are <em|free> in the sense of the
<hlink|definition|http://www.gnu.org/philosophy/free-sw.html> of
``free'' according to the <name|Free Software Foundation>. Other
plug-ins that are not free by this definition (e.g., <name|Matlab>,
<name|Mathematica>, etc.) or not listed above (e.g., <name|Python,
Scilab,> \ etc.) may be available. The best way to check on the
plug-ins included with <TeXmacs> is to view the <var|plugins>
subdirectory of the installation directory. The location of this
directory varies by operating system and distribution.
</note*>

Obviously, any external program supported by an existing plug-in must
be installed in order to be used. In other words, even though it may
be the case that there is an existing plug-in, if the external
program is not accessible by the plug-in for some reason, then a
``dead'' session \ is the likely result.\

<\note*>
As of the date of this document external programs are not
accessible using existing plug-ins for the native <name|MS Windows>
port of <TeXmacs> regardless of whether a <name|Windows> version of
the external program is installed. There are workarounds for this
involving ``live'' <abbr|CDs>, bootable USB ``stick'' memory,
virtual machines (e.g., <name|VirtualBox>) using a <name|GNU Linux>
operating system distribution that supports <TeXmacs> \ and the
relevant external programs as packages.
</note*>

<name|Maxima>, a computer algebra system, is used below to
demonstrate <TeXmacs> sessions using external programs.
</hidden>|<\hidden>
<subsection|<name|Maxima>>

To start a <name|Maxima> session use the <menu|Insert|Session|Maxima>
menu selection. When the session with <name|Maxima> is established
the following banner information appears and then the
\ <with|color|red|<code*|%i>> input prompt
<code*|<with|color|red|(<with|math-font-family|rm|%i>1)>> appears
which is numbered. <name|Maxima> automatically numbers each input and
output line successively during a session unless output is suppressed
in some way. The banner information can be removed using the
<menu|Focus|Remove banner> menu selection. To find the limit of the
function defined by the expression <math|y=x<rsup|2>> as <math|x>
approaches <math|2> the following line is input followed by the
<key|Enter> \ (or <key|Return>) key.

<\session|maxima|default>
<\folded-io>
<with|color|red|(<with|math-font-family|rm|%i>1) >
<|folded-io>
limit(x^2,x,2)
<|folded-io>

<math|<with|math-display|true|<text|<with|font-family|tt|color|red|(<with|math-font-family|rm|%o1>)
>>4>>
</folded-io>

\;

<\textput>
The \ value of the limit is <math|4>. Notice that output lines
use <code*|<with|color|red|(%o)>> and are numbered sequentially
with the input lines.This \ is a text field inserted above the
input line below using <menu|Focus|Insert text field above> menu
selection. There is also a menu selection to insert a text field
below an input line. This feature accommodates explanatory text
or comments before or after input lines.
</textput>
</session>

To split a session in order to enter more text and other content and
then start again with the same session at another point in the
document use the <menu|Focus|Session|Split session> menu selection.
This was done here with cursor at the above input prompt. Then the
same session was continued below by using the
<menu|Insert|Session|Maxima> menu selection again. Notice that the
same input line prompt and number are used.

The displayed output of the expression above can made more elaborate
using some knowledge of how <name|Maxima> works on expressions:

<\session|maxima|default>
<\folded-io>
<with|color|red|(<with|math-font-family|rm|%i>2) >

Notice that the <kbd|disp> function suppresses the output prompt
for the output expression and merely displays the results on the
line following the input. The actual output is <strong|done>.
This is typical Maxima behavior in that every expression has a
value and the value of the <kbd|disp> function is <strong|done>.
This can also be suppressed as follows:

\;
</textput>

<\folded-io>
<with|color|red|(<with|math-font-family|rm|%i>3) >
<|folded-io>
disp('limit(x^2, x, 2)=limit(x^2, x, 2))<math|$>
<|folded-io>
<math|<with|math-display|true|lim<rsub|x\<rightarrow\>2>
x<rsup|2>=4>>

\;
</folded-io>

<\textput>
\;

The <with|color|blue|$> added the end of the input expression
suppresses the output value of the expression, but not the
returned value of the <kbd|disp> function. So the
<with|color|blue|$> does away with <strong|done>, but does not
affect what the function displays. Inserting a $ character as
text presents a problem because <TeXmacs> interprets a $ as a
means to enter math mode. So if a $ is entered from the keyboard
where text is intended it merely starts the math mode and waits
for more input assumed to be math expressions. This is not what
gets the $ inserted which is what is needed here. The way around
this is to use the keyboard sequence <key|Shift+F5> then
<key|Shift+$>. This also works for other characters that
<TeXmacs> uses for special purposes like the <verbatim|\\>. This
can be had by the key sequence <key|Shift+F5> then
<key|Shift+\\>.

<section|Exporting <TeXmacs> Documents>

Documents created using <TeXmacs> are saved in a specific format
using a <verbatim|.tm> file extension by default. These files are
loaded after they are initially created and saved by the user during
the creation process. These files are can be printed or previewed if
supported by the operating system and any required application
packages, and <TeXmacs> is configured for these purposes using the
preferences menu selections <emdash> <menu|Edit|Preferences|Printer>
. This menu selection allows the user to specify the commands to be
used for printing or previewing the document.

However, <TeXmacs> provides the ability to export documents to
different formats including <abbr|HTML>, <LaTeX>, <abbr|PDF>, and
<name|Postscript>. PDF can be used, for example, to distribute the
document by electronic means. In this form it may also be easier to
print the document using any printer on different computers. Use the
menu selection <menu|File|Export> for this purpose.However, <TeXmacs>

PDF can be used, for example, to distribute the document by
electronic means. In this form it may also be easier to print the
document using any printer on different computers. Use the menu
selection <menu|File|Export> for this purpose. <name|Postscript> and
PDF <TeXmacs> converters produce predictable results for most common
page sizes. This means that the resulting file is likely to appear
exactly as the <TeXmacs> source file. The results for <abbr|HTML> and
<LaTeX> <TeXmacs> converters are not as predictable. Expect some
anomalies that may have to be addressed by editing the exported file.

Summary
</section>

<TeXmacs> is an excellent tool for creating technical documents,
especially those containing mathematical expressions. These can be
exported to PDF for viewing, printing, web content, or distribution.
<TeXmacs> relieves the user of the need to be proficient with <LaTeX>
or <TeX>, although a some knowledge of these systems may be useful.
<TeXmacs> provides the user with all the is needed for most routine
technical publications needs and document styles which may be
customized using packages. For those with advanced needs, <TeXmacs>
documents may be exported to <LaTeX> for further processing and
customization. <TeXmacs> even provides the capability to produce
presentation documents using the <verbatim|beamer> style. Finally
<TeXmacs> has a unique capability to be used as an interface to
external programs by way of plug-ins.

The best way to learn how to use <TeXmacs> is to use it. This
platitude assumes the user has the motivation and the perseverance
necessary for making this capable tool useful. <TeXmacs> allows all
types of users to do a lot with little invested in terms of time and
effort, while at the same time providing more ambitious individuals
with an opportunity to ``get under the hood'' with the aim of
mastering a powerful technical document creation tool.
