Split paragraphs into table rows

Question

I am writing a class file. I am defining a variable for my custom \maketitle like so:

\newcommand*{\comment}[1]{\def\commentname{#1}}
\comment{}

I want to be able to write a list of comments like so:

\comment{
    Comment1: this is a comment.

    Comment2: this is also a comment.

    etc.
}

Then I would like my \maketitle to form a table with each of the comments in a separate row. The table should preferably have a dynamic number of rows so that added comments increase the size of the table.

Is this possible?!

Answer 1

I would use a different input syntax with each comment as a separate command rather than split paragraphs:

\documentclass{article}

\newcounter{comment}
\def\comments{}
\makeatletter
\newcommand\comment[1]{%
\stepcounter{comment}%
\def\tmp##1{\g@addto@macro\comments{Comment ##1 & #1\\}}%
\expandafter\tmp\expandafter{\the\c@comment}}

\makeatother

\begin{document}

\comment{first thing}

\comment {second thing}

\comment {a very very liong third thing}




\begin{tabular}{|l|c|}
\comments
\end{tabular}

\end{document}

---

Or if you want explicit comment labels rather than a counter, it is a bit easier

\documentclass{article}

\newcounter{comment}
\def\comments{}
\makeatletter
\newcommand\comment[2]{%
\g@addto@macro\comments{Comment #1 & #2\\}}

\makeatother

\begin{document}


\comment{com 1}{first thing}

\comment{com B}{second thing}

\comment{comment three}{a very very liong third thing}




\begin{tabular}{|l|c|}
\comments
\end{tabular}

\end{document}
