The fourth Alpha version of the upcoming TeXnicCenter 2.0 has been released. As it’s still alpha, it is not stable, it may crash and it’s intended for testing only. It can be used alongside TeXnicCenter Version 1.0, both can be used when installed in different directories, like the previous alpha versions.

Some of the changes:

• Completely new File View with support for TortoiseSVN and similar tools.
• Preprocessors are now supported when building the output.
• The editor knows much more commands and options now. For example, multiple selections are now possible.
• File extensions managed by TeXnicCenter can be chosen through the ‘Default Programs’ control panel.
• Native 64 bit support.
• It is (again) possible to cycle through the documents in Most-Recently-Used order. Also, a long-standing issue with shortcuts using the Alt key has been fixed.

For the long list of changes and fixes, have a look at the announcement by Tino Weinkauf and the TeXnicCenter Team, also posted on LaTeX-Community.org: TeXnicCenter 2.0 Alpha 4.

Untypical for a Q&A site, there’s currently an exchange of views on TeX.SX:

As an expert, can you always use TeX for (nearly) any kind of document?
 

“Yes, you can:”

• It’s easy if you are a routine user, you know the common packages.
• Typing a letter, for example, is just like 20 TeX commands added to the text.
• You get the best possible hyphenation and justification, and a professional consistent look - why to abandon it for a “simple” document.
• After some time you’ve got a lot of documents to use as a template or as a start for a similar document.
• Your, let’s say, 16 years old document still work today. Try documents made with a word processor 16 years ago - can you open it today with current software, without layout loss or change?
• TeX users naturally have TeX installed. Some have a dislike for installing a huge wordprocessing software or suite such as Open/LibreOffice or MS Office - this is overkill for simple documents.

“No, you cannot:”

• For typesetting music, TeX may not be the best choice. Though there’s MusiXTeX, Lilipond seems to be favored.
• TeX should not be used for documents intended for quick onscreen use, such as manual pages which should be readable in a text console window. mandoc and Groff are recommended.

There are 16 answers until know. Perhaps you have a new important point to add? See the original answers with further points.

Agodemar posted a very nice diagram of the LaTeX workflow on TeX.SX:

A bigger version of the image and a link the full source code is shown in the topic Diagram / Infographic of TeX & friends.

Yesterday Seamus Bradley started a topic on TeX.SX:

    Best practice on organising your preamble

For large and highly customized documents, preambles can be lengthy. Should all packages be loaded before macros are defined? Or should packages and related definitions be close together? What about externalizing settings, and handling package dependencies?

Until now, there are two answers.

Yiannis Lazarides’ recommendations:

• Consider developing your own class or package to hold your changes.
• Have the packages and own related commands, near each other.
• Divide the preamble into topics, such as typography, graphics, maths, sectioning etc.
• Have the problematic package settings in their own packages or files.

Mico Loretan’s recommendations:

• Put the entire preamble content into a .sty file. Besides separating the settings from the document content, it has the benefit that you don’t need to use \makeatletter and \makeatother there.
• Check each loaded package if it’s really needed.
• Check your definitions, if there’s a package which could replace them, simpler and perhaps better.
• Use comments and whitespace liberally, to keep your preamble readable.
• A complex preamble could have an overview, a guide like a small table of contents.
• Divide the preamble into topics or tasks.
• Packages, which are loaded without any options, could be loaded by a single \usepackage command, however it would be good to put each package on its own line then.

Justin Bailey’s advice:

• For preambles that load a lot of packages or large packages, such as TikZ, you could create a format file, speeding up compilation.

Justin added a How-To for creating format files for TeX in six steps.

For reasons and explanation, have a look at the original topic.

TeXmaker version 3.2.2 has been released today. New features, from the ChangeLog file, to 3.2.1:

• Block selection mode has been added (alt+mouse).
• The shortcuts of the “Tool” and “Edit” menus can now be modified.
• While using the “New by copying an existing file” command, the directory of the file is now stored.
• The list of asymptote and tikz tags has been completed.
• Users can now hide the pstricks/metapost/tikz/asymptote icons in the structure panels by clicking on the tool bar.
• Users can now hide some commands in the left tool bar of the editor.
• The “underline” tag is replaced by the “emphasis” tag in the left toolbar of the editor.
• If errors are detected, the log file is now displayed even if the “quick build” command is not used.
• After setting a document as “master”, the structure and the bibliography are rescanned.

3.2.1 to 3.2:

• Faster syntax highlighting and structure checking
• An additional parameter (#) for the current file name is available for the commands (required for pdf synchronization with the sumatra pdf viewer).
• The log panel can now be closed directly with the escape key.

Several bugs have been fixed. The complete ChangeLog can be found here. Click here for downloading versions for Linux, Mac OS X or Windows or source files.

Happy New Year, and the best wishes!

TeXample.net is now on Twitter. TeXample.net is a web site dedicated to TeX and related software, currently it’s focussed on collecting and showing TikZ examples.

Follow @TeXgallery to read about new contributions and site features.

Four TikZ examples have been added this week, more are planned, as well as new site features. Twitter will inform about smaller updates, blog posts about bigger changes.

The @TeXgallery Twitter logo is a Koch snowflake, which can be produced using TikZ:

\documentclass{article} \usepackage{tikz} \usetikzlibrary{lindenmayersystems} \usetikzlibrary[shadings] \begin{document} \begin{tikzpicture} \shadedraw[shading=color wheel] [l-system={rule set={F -> F-F++F-F}, step=2pt, angle=60, axiom=F++F++F, order=4}] lindenmayer system -- cycle; \end{tikzpicture} \end{document}

This is also one of the recently added examples.

The maintenance release 2.0.2 of LyX has been published. New and updated features are:

Redfiloux asked on TeX.SX:

 
How to decorate a \path?
 

My question is about drawing a “commutative-type diagram” in mathematics. I would like to integrate an arrow of the type \rightsquigarrow, which is described how to be obtained here: Squiggly arrows in TikZ.

The problem is that I use \path to connect the entries of my matrix in TikZ (because this part comes integrated in a bigger diagram), and I get an error:

“Package PGF Error: I cannot decorate an empty path.”

The code is

\documentclass{article} \usepackage{tikz} \usetikzlibrary{decorations.pathmorphing} \usepackage{amssymb} \begin{document} \begin{tikzpicture} \matrix (m) [matrix of math nodes, row sep=3em, column sep=4em, text height=2ex, text depth=0.25ex] { U & U \\}; \path [->, font=\scriptsize, line join=round, decoration={zigzag,segment length=4, amplitude=.9,post=lineto,post length=2pt}, decorate] (m-1-1) edge node[auto] {F} (m-1-2); \end{tikzpicture} \end{document}

where the decorate part does not work.

Answer:

You could specify the decoration to the path, and give the edge the decorate option:

\path [->, decoration={zigzag,segment length=4,amplitude=.9, post=lineto,post length=2pt},font=\scriptsize, line join=round] (m-1-1) edge[decorate] node[auto] {F} (m-1-2); Stefan Kottwitz

From Usenet to Web 2.0 and beyond - Presentation on TUG 2011

I attended the TeX Users Group Conference 2011 in Trivandrum, Kerala, India, from October 19 to October 21. On this meeting I made a presentation about TeX online communities, such as discussion groups, mailing lists and web forums. I introduced the TeX Q&A site tex.stackexchange.com and showed some of its features which make it a good choice for developing and sharing TeX contents, for building a TeX knowledge base besides just discussing. Finally I compared those systems.

Abstract:

Bringing together TeX users online - from Usenet to Web 2.0 and beyond

It all began with the Usenet, around 1980. The online discussion board comp.text.tex emerged, where TeX hackers gathered and still populate it today.

On the continuously developing Internet, TeX user groups created mailing lists, built home pages and software archives. Web forums turned up and lowered the barrier for beginners and occasional TeX users for getting support.

Today, TeX’s friends can also follow blogs, news feeds, and take part in vibrant question and answer sites.

In this talk we will look at present online TeX activities.

See also the TUG 2011 conference program.

Next week, October 19-21, the 32nd annual meeting of the TeX Users Group will take place in Trivandrum, Kerala, India. It’s hosted by River Valley Technologies. The conference focuses on document production using LaTeX, TeX, ConTeXt, MetaPost, and related software.
