εFU(b)
FUFU(b) ------------> 1_A FU(b)
| |
|FUε(b) |1_aε(b)
| |
v ε(b) v
FU1_B(b) ------------> 1_B 1_B (b)
output should be
\begin{tikzcd}
FUFU(b) \arrow{r}{εFU(b)} \arrow{d}{FUε(b)} & 1_A \arrow{d}{1_aε(b)} & \mbox{} \\
FU1_B(b) \arrow{r}{ε(b)} & 1_B & \mbox{} \\
\end{tikzcd}
No diagonal arrows.
put single _ to keep absent node position.
η(a)
a-----------> T(a)
|

v
_ a
\begin{tikzcd}
a \arrow{r}{η(a)} & T(a) \arrow{d}{φ} & \mbox{} \\
\mbox{} & a & \mbox{} \\
\end{tikzcd}
Labels have to be next to the horizontal or vertial arrow.
Too short arrow may results shorten label.
There is no automatic conversion for UTF8 chars. ε should be replaced by \varepsilon
