# Configuring auto-completion with TeXstudio

TeXstudio does a pretty good job with autocompletion. For example, when I type \eqref{, it already comes with suggestions, see the example below.

However, suppose that I don't want to use \eqref but a customized command using newcommand (I do this so that I can quickly switch to different styles, e.g., some for journals/conferences "Eq. (1)" is needed, whereas sometimes "(1)" suffices). In this case, TeXstudio does not do the auto-completion, see the example below.

Is it possible to configure TeXstudio such that it does the auto-completion for custom commands that require a reference?

Note that one option is to redefine \eqref using \renewcommand, but I'm looking for another way so that I can use if for many more commands, not just for \eqref.

Here is my MWE:

\documentclass{article}
\usepackage{amsmath}

\newcommand{\alternative}[1]{Eq.~(\ref{#1})}

\begin{document}
$$\label{eq:emc2} E = mc^2$$
I can refer to the equation using \eqref{eq:emc2} and using \alternative{eq:emc2}.
\end{document}


For that, you will have to make use of a custom .cwl file (which, afaik, requires a recent version of TeXstudio).

Create a file, let's say mycwl.cwl, in either %appdata%\texstudio\completion\user or .config/texstudio/completion/user according to your system.

In it, place the following line:

\alternative{label}#r


and save it. Technically, you can put anything meaningful in the argument, but some terms are reserved and have special meaning. And, as you wish TeXstudio to recognize a label there, you require one of those, namely label. The comment at the end of the line tells TeXstudio what kind of command yours is. #r stands for this command declares a reference like "\ref{key}". For further commands, just add a new line to your mycwl.cwl.

Then, in TeXstudio, go to Options -> Configure TeXstudio -> Completion and check mycwl.cwl on the list. And that's about it.

For more details on customizing autocompletion with cwl files, check the TeXstudio manual, section "4.13 Description of the cwl format".

A tip: If the manual seems complicated, and you'd like to emulate the behavior of some command's autocompletion you like, you might want to download the sourcecode tarball at http://texstudio.sourceforge.net/, unpack it and look at the built-in cwl files in the "completion" folder. From there, you can proceed by means of examples of your commands of interest.

• Wow, that would have taken me hours to figure this out (if I ever succeeded). Thanks, it works like a charm! – EdG Feb 8 '18 at 11:54
• @EdG, glad to hear. Btw, it would have been kind of you if you had posted your MWE as code, rather than image, so that you did not leave to others the work of retyping. I still think it is a good idea for you to add it to the question. – gusbrs Feb 8 '18 at 12:00
• Oh oops, that's stupid from me. Will add it now! Thanks for the feedback. – EdG Feb 8 '18 at 12:02
• @COTO, thanks for the edit, I indeed missed the typo. – gusbrs Feb 12 '18 at 15:31
• off topic: Do you know about \eqref{} which inserts ( ) automatically? – Sigur Feb 12 '18 at 15:37

I suggest to use the cleveref package instead of manually defining commands for all possible types of labels.

• cleveref will automatically insert the appropriate string based on the type of label you are referring to

• texstudio automatically suggest possible labels

\documentclass{article}
\usepackage{amsmath}
\usepackage[capitalise]{cleveref}

\begin{document}
$$\label{eq:emc2} E = mc^2$$
I can refer to the equation using \eqref{eq:emc2} and using \cref{eq:emc2}.

\end{document}

• I took the question in abstract form, but that is certainly good advice! (+1) – gusbrs Feb 8 '18 at 12:48
• Btw, you see I finally updated my TS, stimulated by an answer of yours not long ago. :) – gusbrs Feb 8 '18 at 12:50
• @gusbrs :) I wish you a lot of fun with your updated TS! I am eagerly waiting for version 2.12.8 because of this commit: github.com/texstudio-org/texstudio/commit/… – user36296 Feb 8 '18 at 13:36
• @samcarter Thanks for your answer. Though it is not an exact answer to my question, it's a very good advice (+1). I did not know of cleverref, but now I do :) – EdG Feb 8 '18 at 13:40
• hahaha! Indeed, the only conceivable reason why this was not part of TS since version 0.1 beta is that tikzducks was not available then. :) – gusbrs Feb 8 '18 at 13:42
