Check if mmode Command Doesn't Work in Tikz-cd environment












2















I have a command that allows me to write terminal in math mode and it print in its bb-bold style, but also allows me to call it in text mode as terminal (as opposed to (terminal) or whatever). The math font I've used is a result of the difficulty of finding nice look bb-bold characters for 0 and 1 as initial and terminal objects (category theory).



However, I think the check breaks down when the command is called in a tikz-cd environment causing me to get a lot of errors (missing delimiters, missing math mode, math font called in text mode, etc.). is there an easy fix that allows me to continue using the same terminal command in and out of math mode?

  • You gain nothing by defining terminal so that it works in text mode: you'd need terminal{} if you use it in text, and $terminal$ is the same number of keys and clearer because it segregates math. Anyway, if you want to roll on your own version of ensuremath, add relax in front of ifmmode. See tex.stackexchange.com/q/34830/4427

    Also, I find arrow[r,"eta"] much clearer than the obscure rar.

  • @egreg I type terminal and it prints fine. I know it sounds silly but typing the dollar signs slows me down and the accepted answer provides an easy enough macro to avoid that necessity. Thanks for the feedback though. EDIT: to your second comment, I currently have some 50 commutative diagrams in this document, and the time saving of using shortcuts like rar or ular is worth the sacrifice in readability (to me).

            How to change which sound is reproduced for terminal bell?

            Image
            3 Recently upgrade to 18.10 from 18.04, and using the terminal is becoming annoying: the new alert sound is a drip ( /usr/share/sounds/gnome/default/alerts/drip.ogg ), and the previous one is still located at ( /usr/share/sounds/ubuntu/stereo/bell.ogg ). My issue is that at the gnome-terminal, when autocompleting or pressing left BOTH sounds are reproduced, at the same time. I want to just have ubuntu/stereo/bell.ogg active, not both . At the moment I have been only able to reduce the volume of the alerts (but still both are played), or turn the alerts down (but I dislike both "solutions"). gnome-terminal 18.10 teminal-bell share | improve this question ...

            Title Spacing in Bjornstrup Chapter, Removing Chapter Number From Contents

            Image
            up vote 5 down vote favorite 2 I would like to make it so that the vertical space below the title of each chapter is the same when using the Bjornstrup package (i.e. so that the descenders do not affect the spacing - as shown by the red arrow in the picture below). I think I'm fairly happy with the spacing around "A chapter", so I'd really like titles without descenders (e.g. "Contents") to have the same vertical spacing as "A chapter" below the title.
