So I have a document where I have a bunch of compound names. (e.g. \lambda_v-C(t)-\rhd.) The - character in the equation context is understood as a minus sign and is WAY too long for compound names.

I know one options is to switch to a text context, (e.g. \lambda_v \text{-} C(t) \text{-} \rhd).

This works, but it's really wordy and annoying. Since I never use a minus sign in any equation in this document, I'd like the - character to automatically be displayed as the hyphen even in equation contexts. Is there a way to do this?

Alternatively, \\- or some other very short sequence would work too.

\documentclass{article} \usepackage{amssymb} \mathcode`-=`- \begin{document} $\lambda_v-C(t)-\rhd$ \end{document}

However I suspect that you want a real arrow with “C(t)” in the middle, don't you?

Something like

\documentclass{article} \usepackage{tikz-cd} \tikzcdset{arrows={-Triangle[open]},every label=\textstyle} \newcommand{\AR}[1]{% \hspace{-0.5em}% \begin{tikzcd}[ ampersand replacement=\&, column sep=large, ] {}\arrow[r,"#1" description]\&{} \end{tikzcd}% \hspace{-0.5em}% } \begin{document} $\lambda_v \AR{C(t)} \mu$ \end{document}

arrow

  • Thanks, that works. To answer your question, no, I actually have compound names with triangles in them... (They represent computation rules in some extensions of the lambda calculus) Commented Mar 3 at 17:35

    @azani You should use {\rhd} or the spacing can go awry. Commented Mar 3 at 18:06

Assuming you have only a few of these names, you can define a shortcut for each, say,

\newcommand{\LC}{\ensuremath{\lambda_v \text{-} C(t) \text{-} \rhd}}

and then simply type \LC when you need it. This way the minus sign is unaltered and remains available with its standard meaning, should you require it.
