Sumatra PDF erschienen

Thorsten schrieb gerade auf, dass die Version 2.0 des freien Sumatra PDF Readers veröffentlicht wurde. Dieser PDF-Betrachter ist bekannt für seine Geschwindigkeit und für seine gute schlichte Benutzer-Schnittstelle. Mit ihm funktioniert Vorwärts- und Rückwärtsuche mit TeX-Quellcode und PDF-Ausgabe besonders gut, und er blockiert nicht geöffnete Dateien, wie andere Reader es tun.

Verglichen mit Version 1.9 bringt dieses Major Release ein paar Änderungen, wie in den News genannt:

  • Er unterstützt das MOBI eBook-Format.
  • CHM-Dokumente können von Netzlaufwerken geöffnet werden.
  • Eine Auswahl kann als Bild in die Zwischenablage kopiert werden, indem man das Kontextmenü mittels rechtem Mausklick benutzt.
  • Er verwendet ucrt, um die Programmgröße zu reduzieren.

Sumatra PDF 2.0 released

Thorsten just posted on, that the version 2.0 of the free Sumatra PDF reader has been released. This PDF reader is known for its speed and its nice simple user interface. It works especially well with forward and inverse search with TeX source and PDF output and it doesn’t lock opened files like as other readers do.

Compared to v1.9, this major release brings a few changes, as announced in the news:

  • It supports the MOBI eBook format.
  • CHM documents can be opened from network drives.
  • A selection can be copied to the clipboard as an image by using the right-click context menu.
  • It uses ucrt to reduce the program size.

Drawing a stemma with TikZ

Maïeul Rouquette has published an article on Stemma with TikZ. It is an English translation of his three French blog articles about that topic.

A stemma codicum is a “family tree” of different manuscripts of a same text, see Stemmatics (Wikipedia). The article explains how to draw such a tree, which is also a method for constructing TikZ trees in general:

  • For simple trees, use nodes, edges and children with the TikZ tree syntax
  • For complex trees, you can go through these steps:
    1. Place the nodes, using coordinates or relatiive positioning, and give them names
    2. Apply styles for the nodes, choose or define your own styles for this
    3. Connect nodes by lines or arrows such as by draw[->] (node1) — (node2);
Stemma with Tikz

Once you have created such a tree, you could easily use this as a template for further trees, if you don’t like to go through such a construction process each time. Though some things seem to be complicated with TikZ, it’s easy to re-use and to adjust for similar drawings. For this, the TikZ example gallery can give good start code. It also provides some examples for TikZ trees.

TeXworks needs testers

Stefan Löffler wrote to the TeXworks mailing list, that helping participants are needed for trying the latest TeXworks 0.5 r979. This is for preparing the release of version 0.4.4, which is expected to come mid-April, for the inclusion in TeX Live 2012. Recent Windows and Ubuntu builds are available, a Mac build is planned to be provided very soon.

Especially changed features need testing, such as

  • The rewritten log parser
  • Search & replace (such as multi-line copy-to-search/replace)
  • Check if the problems with the disappearing lines still exist
  • Reproducing the crash of TeXworks when pressing the return key at the beginning of a wrapped line. Did you ever notice it?

If you would like to help, download the latest build and test it, and send your test results to Stefan or to the TeXworks mailing list.

Document Freedom Day

Today is the “Document Freedom Day”. Today, we can celebrate information accessibility, and we could raise awareness of open standards, which mean document formats which

  • can fully publicly used without constraints,
  • don’t have dependencies on formats or protocols that are not open,
  • are legally and technically unlimited in utilisation,
  • are maintained and further developed independently of any single vendor
  • and are available in various implementations by competing vendors or just freely available.

Let’s look at TeX and LaTeX. The source document format is plain text, usable on any platform. Only the encoding can be a small issue between operating systems or editors, which can be handled by freely available conversion tools. Furthermore, Unicode text is commonly supported today. But ASCII still works everywhere, while Unicode is convenient.

And the output? Well, PDF is commonly chosen today and widely supported, though I would not call it an open standard, just in parts. However, we have the source, and we still have the DVI format. I wish there were better onscreen display programs.

With nonfree document formats, TeX and LaTeX would hardly be as useful as today, compatible and cross-platform. I can work with my up to 16 year old LaTeX documents in best quality on any hardware today – try it with so old Word or Works files.

For general information regarding free documents and open standards, have a look at

Lucida OpenType verfügbar

Heute schrieb Karl Berry auf der texhax mailing list, dass die Lucida OpenType Schrift nun verfügbar ist. Lucida ist von der TeX Users Group (TUG) erhältlich: hält Bestell-Informationen zusammen mit weiteren Dokumenten und Beispielen bereit.

Lucida ist eine Schriftfamilie, die von Bigelow & Holmes gestaltet wurde. Sie bietet viele Varianten wie Serifenschift, serifenlose, Script und Monotype, und wurde erweitert um ein vollständiges Set an TeX Mathematiksymbolen. Sehr wenige Schriften unterstützen sowohl Text- als auch Mathematik-Satz, was Lucida außergewöhnlich macht.

Seit langer Zeit schon gibt es eine Type 1 (PostScript) Version von Lucida, die jedoch nur 8-bit Zeichensätze unterstützt. Diese Version wird nicht weiterentwickelt. Doch die OpenType Version wird weiterhin gepflegt und entwickelt. Lucida OpenType bietet z.B. sogar eine fette Mathematikschrift.

Die Lucida-Schriften sind nicht frei verfügbar, sie können bei der TUG gekauft werden mit einem Rabatt für TUG-Mitglieder.

Lucida OpenType available

Today Karl Berry announced on the texhax mailing list, that the Lucida OpenType font distribution is now available. You can get it from the TeX Users Group (TUG): provides ordering information together with documents and samples.

Lucida is a family of typefaces which has been designed by Bigelow & Holmes. It includes many variants, such as serif, sans serif, scripts, and monospaced. It has been extended to contain a full set of TeX mathematical symbols. Very few fonts support both text and math typesetting, which means Lucida is very exceptional.

Since a long time, there’s been a Type 1 (PostScript) version of Lucida, which supports only 8-bit character sets. This version will not be developed further. But the OpenType version will be maintained and developed. Lucida OpenType even provides a bold math variant.

The Lucida fonts are not redistributable, they can be ordered from TUG with a discount for TUG members.

Who has experience with OS X?

Just today I read a post by Markus Kohm on, which he wrote one week ago: the work on the the English version of the KOMA-Script manual is in progress. I know that many people in the international TeX community are waiting for it. Some users can hardly understand the German manual while the former English translation is very outdated.

However, the good soul who is working on the translation, works on Mac OS X, and there are some problems with the make process of the KOMA-Script manual sources.

If you have experience with OS X and if you would like to help in solving technical problems, or if you know somebody who would like to help, it would be great if you would contact Markus Kohm. You could just write him an email or post a comment on

The KOMA-Script classes and packages are a very valuable contribution to the LaTeX software, that’s why I would appreciate any help in supporting the translation.

See also: The English guide seems to be out-dated. Is there a newer one anywhere?
