Text Formatting ⇒ tocloft package and problem with equation labels

[gkl]

Dear All,

I am using the tocloft package to generate a list of equations I have in my thesis for the table of contents. It builds successfully with the following code:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
\newcommand{\listequationsname}{List of Equations}
\newlistof{myequations}{equ}{\listequationsname}
\newcommand{\myequations}[1]{%
%\refstepcounter{myequations}
%\par\noindent\textbf{Equation \theequation. #1}
\addcontentsline{equ}{myequations}{\protect\numberline{\theequation}#1}\par}
 
 
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Run LaTeX here

Now if I want to have a title for the equation I will do something like:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
\begin{equation}
\label{eq:pythagoras}
$$\myequations{Test}$$
x^2 + y^2 = z^2
\end{equation}

Run LaTeX here

This will get the entry in the table of contents, but will remove the label - you can no longer say

Code: Select all

1
look at equation~\ref{eq:pythagoras}

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

, it will just give you the section's number.

Any ideas as to how to fix this?

Can you provide a minimal working example showing the misbehavior? If I simply do:

Run LaTeX here

then the \ref command works just fine.

(By the way, I recommend using \text rather than $$..$$ to escape back to text mode inside the equation, but I don't think that's your problem. Also, I wonder why you don't use \newlistentry instead of \addcontentsline)

[gkl]

I haven't considered using \text and \listentry to be honest. However, I found that the problem can be solved by simply moving the \myequations command outside the equation environment and have it immediately after the equation code.

I think this is because \addtocontentsline uses the equation counter (\theequation) so it might be resetting it or something but just moving it outside the equation block did the trick.
