'''GNU TeXmacs''' is a [[Free software|free]] scientific [[word processor]] and [[typesetting]] component of the [[GNU Project]]. It was inspired by [[TeX]] and [[GNU Emacs]], though it shares no code with those programs.  TeXmacs does use TeX fonts.<ref>[http://www.texmacs.org/tmweb/help/faq.en.html Frequently asked questions (FSF GNU project)<!-- Bot generated title -->]</ref> It is written and maintained by [[Joris van der Hoeven]]. The program produces structured [[document]]s with a [[WYSIWYW]] [[user interface]]. New document styles can be created by the user. The editor provides high-quality [[typesetting]] [[algorithm]]s and TeX [[typeface|font]]s for publishing professional looking documents.
 
==Features==
TeXmacs can handle mathematical [[formula]]s and is used as a front-end to a number of [[computer algebra system]]s such as [[Maxima (software)|Maxima]] and [[Sage (mathematics software)|Sage]]. TeXmacs also supports a [[Scheme (programming language)|Scheme]] extension language called [[GNU Guile|Guile]] for customizing the program and writing extensions.
 
Like many WYSIWYG editors (such as [[Microsoft Word]]), authors manipulate a document on screen which should print to a similar looking paper copy. The goal of TeXmacs is to provide a WYSIWYG editor that nevertheless makes it possible to write correctly structured documents with aesthetically pleasing typesetting results. TeXmacs is not a front-end to [[LaTeX]] but TeXmacs documents can be converted to either [[TeX]] or LaTeX. Support for [[HTML]], [[MathML]] and [[XML]] is under development.
 
TeXmacs currently runs on most Unix-based architectures including [[Linux]], [[FreeBSD]], [[Cygwin]] and [[Mac OS X]]. Along with the Cygwin version, a native beta [[Porting|port]] is available for [[Microsoft Windows]].
 
TeXmacs also features a [[presentation software|presentation]] mode and there are plans to evolve towards a complete scientific [[office suite]] with [[spreadsheet]] capacities and a [[technical drawing]] editor.
 
=== Mathematic typography ===
With TeXmacs, it is easy and fast to type mathematical formulas. For example, the symbol <math>\Rightarrow</math> can be obtained by typing <tt>=></tt>. Some variants, such as <math>\Uparrow</math>, can be obtained using the <tt>tab</tt> key. Hence, a wide range of symbols are accessible easily using user-friendly keyboard shortcuts.<ref>See the user manual : « [http://www.texmacs.org/tmweb/manual/webman-math.en.html#auto-6 Typing mathematical symbols] ».</ref>
 
=== Batch processing ===
It is possible to use TeXmacs as a [[batch processing|batch processor]] (which is [[LaTeX]]'s usual operation mode), using [[Xvfb|X virtual framebuffer]] to avoid opening unwanted windows while processing. For example, the command
xvfb-run texmacs --convert article.tm article.pdf --quit
generates a [[PDF]] file "article.pdf" from a TeXmacs document "article.tm".
 
==Supported back ends==

TeXmacs has back-ends supporting many technologies.
 
Programming languages:
[[CLISP]], [[CMU Common Lisp|CMUCL]], [[Python (programming language)|Python]], [[Quantum programming#Quantum computing language|QCL]], [[R (programming language)|R]], [[Shell (computing)|Shell]]
 
Computer algebra systems:
[[Axiom (computer algebra system)|Axiom]], [[Xcas|Giac]], [[Macaulay 2]], [[Mathematica]], [[Maxima (software)|Maxima]], [[Mupad]], [[PARI/GP]], [[Reduce (computer algebra system)|Reduce]], [[Sage (mathematics software)|Sage]], [[Yacas]]
 
Numeric matrix systems:
[[GNU Octave]], Matlab, [[Scilab]]
 
Plotting packages:
[[gnuplot]], [[Graphviz]], [[XYpic]], [[Mathemagix]]
 
Other:
[[DraTeX]], [[Eukleides]], [[GTybalt]], [[Lush (programming language)|Lush]]

There is nothing to say about myself at all.
Feels good to be a member of wmflabs.org.
I just wish Im useful in some way .
