## New Lexicon: how to add a custom minted lexer in Overleaf

This quick post comes courtesy of LianTze Lim (an Overleaf TeXpert) and Kota Miura (a bioimage analyst).

I asked on the ImageJ forum some time ago how to add an ImageJ Macro lexer for a LaTeX document I was writing. Kota responded with this lexer for pygments. I then asked Overleaf if it was possible to add a custom lexer to an Overleaf document using the minted package. At the time this was not possible. However, I got a message from them today with a solution.

Steps to do this for your own Overleaf project:

\begin{minted}{imagejmacro.py:ImageJMacroLexer -x}
\end{minted}

Here, imagejmacro.py is the name of the custom lexer saved in your project and ImageJMacroLexer is the name of the class in that file. If you want to use another custom lexer just replace as required. I have put up a read-only Overleaf example to show it working.

Thanks to LianTze for following up with me about this and special thanks to Kota who wrote the custom lexer.

## In a Word: LaTeX to Word and vice versa

Here’s a quick tech tip. We’ve been writing papers in TeX recently, using Overleaf as a way to write collaboratively. This works great but sometimes, a Word file is required by the publisher. So how do you convert from one to the other quickly and with the least hassle?

If you Google this question (as I did), you will find a number of suggestions which vary in the amount of effort required. Methods include latex2rtf or pandoc. Here’s what worked for me:

• Exporting the TeX file as PDF from Overleaf
• Opening it in Microsoft Word
• That was it!

OK, that wasn’t quite it. It did not work at all on a Mac. I had to use a Windows machine running Word. The formatting was maintained and the pictures imported OK. Note that this was a short article with three figures and hardly any special notation (it’s possible this doesn’t work as well on more complex documents). A couple of corrections were needed: hyphenation at the end of the line was deleted during the import which borked actual hyphenated words which happened to span two lines; and the units generated by siunitx were missing a space between the number and unit. Otherwise it was pretty straightforward. So straightforward that I thought I’d write a quick post in case it helps other people.

What about going the other way?

Again, on Windows I used Apache OpenOffice to open my Word document and save it as an otd file. I then used the writer2latex filter to make a .tex file with all the embedded images saved in a folder. These could then be uploaded to Overleaf. With a bit of formatting work, I was up-and-running.

I had heard that many publishers, even those that say that they accept manuscripts as TeX files actually require a Word document for typesetting. This is because, I guess, they have workflows set up to make the publisher version which must start with a Word document and nothing else. What’s more worrying is that in these cases, if you don’t supply one, they will convert it for you before putting into the workflow. It’s probably better to do this yourself and check the conversion to reduce errors at the proof stage.
