## What’s new in chemmacros v5.6?

Version 5.6 (2016/05/02) of chemmacros comes with a whole bunch of improvements and changes – no breaking changes, though. Here’s an overview over the changes:

## New chemmacros module “polymers”

As of version 5.5 the chemmacros package includes a new module named polymers. Currently it mostly defines a few macros for usage in the \iupac command (provided by the mandatory nomenclature module) such as

## a new chemmacros – but how?

I have written earlier about a new concept for chemmacros and about the current development of chemmacros. I really want to go along with e idea of modularity. In fact so much that I already have a draft completed (without manual and probably a number of bugs but still…). The big question is, though: How do I procede without annoying all the users of chemmacros? If I am consequent with the modularity then there need to be breaking changes.

## The Template Story

In the LaTeX community templates for documents are a recurring topic of discussion. I have written about it:

It all boils down to this: templates often contain bad code or don’t follow good LaTeX practice but on the same time many not so experienced users like to use templates for their documents. This is the source for many, many problems and questions in LaTeX forums and Q&A sites.

## Name change and other changes

Yesterday I’ve changed the name of this blog. The reason is that I’d like to change the focus of this blog away from chemistry in LaTeX.

More precisely I want LaTeX in general to be the topic. That doesn’t mean I won’t be writing about chemistry in LaTeX any more – of course I still will. But there are so much more topics worth writing about! Certainly one main focus will be news about the development of my packages (one reason for not focussing on the chemistry part: I have a number of packages not related to chemistry at all!).

As you know I have always had a long list of links on the right-hand or left-hand side of this blog. I have moved these to a dedicated page: the Link Library. I also added the possibility for you to submit new links which you think are missing from the list. Have a look at the new page and at the links and submit any LaTeX related link which is missing from the list. Enjoy!

## ideas, ideas, ideas

Lately I am full of ideas – not only concerning chemmacros and new packages as you might have gathered from recent posts – but also regarding this website.

## new package: elements

While working on chemmacros I found I wanted to use some functionality which is currently provided by the package bohr. But since I only wanted part of the functionality I realised that the same was true for bohr: it needed the functionality but wasn’t originally designed to provide it. It made sense to extract said functionality into a package of its own, extended with further functioniality. Long story short: there’s a new package called elements which will be sent to CTAN once bohr is updated to use the new package.

June 24th, 2015: elements has been sent to CTAN, bohr has been updated to v1.0.

## modern times

Like it if you like it :)

## modular chemmacros

OK, it’s been a while since I’ve posted anything. But now it’s time to discuss a few ideas I have about chemmacros. As you are probably aware if you are a user of the package: it provides lots of different stuff. At least in my experience it is rarely the case that you need all of its features.

## Carbohydrates

Since a few weeks I’m working on a package using chemfig as a backend that allows a simple yet flexible input syntax for typesetting carbohydrates. My draft at this point allows the following:

\documentclass{scrartcl}
\usepackage{carbohydrates}
\begin{document}

\glucose[model=chair,ring]

\end{document
}

which gives:

## Old new friend

A few weeks ago Shin­saku Fu­jita submitted a new update of XyMTeX to CTAN. Why is this worth mentioning? Because of two (or three) reasons:

## Documents With Style

People have asked me how I create the manuals of my packages, one has even asked me if I would write a document class similar to classicthesis. I am not going to do this but can provide my basic preamble settings. It is not very complicated, actually.

## chemmacros v4.0

My chemmacros bundle has reached version 4.0. The step to a new major version has been made for two reasons: 1) the bundle has been extended with a new package: chemgreek. 2) every sub package can now be loaded and used independently. In all versions 3.* the ghsystem package, the chemformula package and the chemmacros package have loaded each other which made them one single package, really. This is no longer true. While chemmacros still loads ghsystem and chemformula (and also the new package chemgreek) the same is not true for ghsystem, chemformula or chemgreek. If they’re loaded alone they won’t load any other package of the bundle.
