# Showterm: Draw Prolog terms as trees in Emacs
|
|
|
|
To try it, you need the following programs installed:
|
|
|
|
- [**Scryer Prolog**](https://github.com/mthom/scryer-prolog)
|
|
- `dot` (from Graphviz)
|
|
- `convert` (from ImageMagick)
|
|
|
|
Copy [`showterm.el`](showterm.el) and [`showterm.pl`](showterm.pl) to
|
|
the same directory, say `~/scryer-prolog/tools/`, and add to your
|
|
`.emacs`:
|
|
|
|
(load "~/scryer-prolog/tools/showterm.el")
|
|
|
|
If necessary, set `scryer-prolog-path` to the Scryer Prolog
|
|
executable by adding to your `.emacs` (adapting as appropriate):
|
|
|
|
(setq scryer-prolog-path "/usr/local/bin/scryer-prolog")
|
|
|
|
The function `showterm` draws the Prolog term in the region as
|
|
a tree. You can invoke it with `M-x showterm RET`, or for example
|
|
by binding it to a key in your `.emacs`, and then pressing
|
|
that key:
|
|
|
|
(global-set-key [f12] 'showterm)
|
|
|
|
Enjoy!
