The SWI-Prolog development environment consists of a number of
interrelated but not (yet) integrated tools. Here is a list of the most
important features and tips.
- Atom completion
The console48On Windows this is
realised by swipl-win.exe, on Unix through the GNU readline library,
which is included automatically when found by configure.
completes a partial atom on the TAB key and shows
alternatives on the command Alt-?.
- Use edit/1
for finding locations
The command edit/1
takes the name of a file, module, predicate or other entity registered
through extensions and starts the user's preferred editor at the right
location.
- Select editor
External editors are selected using the EDITOR environment
variable, by setting the Prolog flag editor,
or by defining the hook prolog_edit:edit_source/1.
- Update Prolog after editing
Using make/0,
all files you have edited are re-loaded.
- PceEmacs
Offers syntax highlighting and checking based on real-time parsing of
the editor's buffer, layout support and navigation support.
- Using the graphical debugger
The predicates guitracer/0
and noguitracer/0
switch between traditional text-based and window-based debugging. The
tracer is activated using the trace/0, spy/1
or menu items from PceEmacs or the Prolog Navigator.
- The Prolog Navigator
Shows the file structure and structure inside the file. It allows for
loading files, editing, setting spy points, etc.
