# Indented block in ConTeXt

I need to write pseudocode in ConTeXt. Since there is no documentation of the t-algorithmic module, and because I don't have so much to write, I decided to format the code myself.

Here is what I tried:

\def\>{\space\space\space\space}

{\bf for all} $i \in [0, 43[$\\
\>  blah blah


Sadly, this doesn't work. How can I indent a specific line ? Or an entire paragraph.

Thanks !

• The documentation for the algorithmic module can be found on BitBucket. Consider using it. To your problem: You can use \setupindenting[yes,big] \let\>\indent. And watch out, TeX does not eat the space after the >. – Marco Jul 24 '13 at 9:41
• \setupindenting adds indentation for all the paragraphs of the document, how can I avoid this ? Thanks for the documentation ! :) – Simon Jul 24 '13 at 9:48
• Switch the indentation off after you're done with your algorithm: \setupindenting[no] – Marco Jul 24 '13 at 9:52
• Also, for indenting multiple lines you can use the \{start,stop}narrower environment. – Philipp Gesang Jul 24 '13 at 10:25
• If you really want to use the minimal markup that use have, use \def\>{\null\qquad}. Adding the \null ensures that the space at the beinining of the line is not eaten. Another option is to use the lines environment with space=yes – Aditya Jul 24 '13 at 14:44

The documentation for the algorithmic module can be found on BitBucket.. Here I present three solutions, one using the algorithmic module, one which uses the lines environment and your custom \> macro and one which uses the lines environment combined with the narrower environment, which is rather verbose.

\usemodule[algorithmic]
\starttext

\subject{\mono{algorithmic:}}

\startalgorithmic
\FORALL {\math{i \in [0, 43[}}
\STATE blah blah
\STATE more lines
\ENDFOR
\stopalgorithmic

\subject{\mono{lines} and custom macro:}

\def\>{\quad}
\startlines
{\bf for all} \math{i \in [0, 43[}
\>blah blah
\>more lines
\stoplines

\subject{\mono{lines} and \mono{narrower}:}

\startlines
{\bf for all} \math{i \in [0, 43[}
\startnarrower
blah blah
more lines
\stopnarrower
\stoplines

\stoptext
