Since there has been progress concerning the indentation, notable also
in algpseudocode.el I would like to point out a problem I reported some
time ago and which causes some headaches for proper indenting.
These are latex constructs like
\begin{equation}
\label{eq:cnv_2022_03_24_389c19861457ad3e9b90g:94}
\left|c_{k}\right|=\left|\frac{\alpha_{k}-\omega
\beta_{k}}{\alpha_{r}}\right| \rightarrow\left\{\begin{array}{ll}
\left|\frac{\alpha_{k}}{\alpha_{r}}\right| & \text { si } \beta_{k}=0 \\
\infty & \text { si } \beta_{k} \neq 0
\end{array} \quad \text { cuando }|\omega| \rightarrow \infty .\right.
\end{equation}
that still get indented as
\begin{equation}
\label{eq:cnv_2022_03_24_389c19861457ad3e9b90g:94}
\left|c_{k}\right|=\left|\frac{\alpha_{k}-\omega
\beta_{k}}{\alpha_{r}}\right| \rightarrow\left\{\begin{array}{ll}
\left|\frac{\alpha_{k}}{\alpha_{r}}\right| & \text { si } \beta_{k}=0 \\
\infty &
\text { si } \beta_{k} \neq 0
\end{array}
\quad \text { cuando }|\omega| \rightarrow \infty .\right.
\end{equation}
The source of the problem is that the \begin{array} should be at the
beginning of the line, or at least not having «text» before it (not sure about
the \end{array}.
Be it as it may. I wrote the ridiculous function
(defun my-change-begin-array-to-newline-begin-array-old ()
(interactive)
(save-excursion
(replace-regexp "\\\\begin{array}\\(\\(.\\|\n\\)*?\\)"
"\n\\\\begin{array}\\1")))
which was reasonable fast, but taking Tassilos remarks into account I
tried.
(defun my-change-begin-array-to-newline-begin-array ()
(interactive)
(while (re-search-forward "\\\\begin{array}\\(\\(.\\|\n\\)*?\\)" nil t)
(replace-match "\n\\\\begin{array}\\1" nil nil)))
But this was much slower.
In any case would someone like to implement this better and even more
general that is all \begin{something} should start at with a newline?
