Math & Science ⇒ Indentation in math mode

[Dick Justice]

Hello forum,

I'm writing a paper in Latex containing excerpts from ProLog code. The paper that I'm writing is about to be merged with a much bigger paper where all predicates are written in a pseudocode-like form:

Code: Select all

head<--
  rule1, 
  rule2,
  ...,
  ruleN.

Which means that I need \leftarrow, which is only available in math mode. However, even though I am able to insert line breaks wherever I like, I am unable to obtain the initial spacing I require so that "ruleX" is indented in the way that I sketch above. I have tried \quad, \qquad, \hspace{} and the like, but to no avail. All forum posts that I have searched tend to specify examples where horizontal spacing techniques are applied to the equation environment, which is of no use to me.

Any tips? Thanks

Hi,

Why don't you use some of the verbatim capabilities of LaTeX? Something along these lines:

Code: Select all

\documentclass{article}
\usepackage{fancyvrb}

\DefineShortVerb{\|}

\begin{document}

|head|$\leftarrow$ \\
|     rule1,|\\
|     rule2,|\\
|     ...,| \\
|     ruleN.|

\end{document}

The listings package could offer you even more flexibility.

Thanks a lot for your input. As it turns out, the people I work with had already design an environment based on \arraycolsep with aim just to address the problem of flexibility with spacing in math mode.

I will use verbatim when I need more flexibility, though.

Marking this solved.
