I took some habits with my sciences reports so I developed some personalized commands.
First, I define in the preamble all the variables that I need like this:
\newcommand{\cvba}{Cv_{\beta/\alpha}}
\newcommand{\za}{z_{\alpha}}
...
Then I begin all my equation labels by "eq:" like in this example :
\begin{equation}
\za = \frac{1000.-T}{34}
\label{eq:za}
\end{equation}
And finally, I set a command which allows me to make a reference from a variable to its definition inside the environment equation :
\newcommand{\eref}[2]{\hyperref[eq:#1]{#2}}
In this example, za will point to the previous equation :
\begin{equation}
\cvba = \eref{za}{\za}+12
\label{eq:cvba}
\end{equation}
My problem is that I would like to make my new command eref a little bit easier and lighter to use such as it takes only one parameter.
I tried to define it like this :
\newcommand{\eref}[1]{\hyperref[eq:#1]{\#1}}
Obviously it doesn't work because the \# is understood as a specific character.
So my question is : "How could I concatenate two strings to make a new command?"
If it can helps, the names of my variables can change, for example they could be \var_varname such as he new command would looks like :
\newcommand{\eref}[1]{\hyperref[eq:#1]{\var_#1}}
