Hi Srihari,

There are four parameters that allow you to control pretty printing (to some extent).
For most tools, they can be set via command-line options

--pp-max-width=<num>
--pp-max-ribbon=<num>
--pp-max-depth=<num>
--pp-num-lines=<num>

For some reason, sal-atg does not seem to support these options. You can fix this by
editing the script sal-atg-front-end.scm (should be in directory <saltopdir>/src).

Search for a line

(front-end/set-categories! '("Help" "Misc" "Module" ....))

then add "Pretty Printing" in there:

(front-end/set-categories! '("Help" "Misc" "Module" "Pretty Printing" ....))


An alternative is to directly set the parameters from within sal-atg by calling
the following functions:

(sal/set-pp-max-depth! max)
(sal/set-pp-max-width! max)
(sal/set-pp-max-ribbon! max)
(sal/set-pp-max-num-lines! max)

For example, you could edit the file sal-atg-front-end.scm and add

(sal/set-pp-max-ribbon! 80)
(sal/set-pp-max-width! 100)

If you have the SAL source, these functions are defined  in sal-pp.scm.
(also check pretty.scm).

Good luck,

Bruno
