3.11 SICStus Prolog IDE

SICStus Prolog IDE, also known as SPIDER, is an Eclipse-based development environment for SICStus with many powerful features.

SPIDER was added in release 4.1 and is described on its own site, http://www.sics.se/sicstus/spider/.

Some of the features of SPIDER are:

Semantic Highligting
Code is highlighted based on semantic properties such as singleton variables, ....
On-the-fly warnings
The editor flags things like calls to undefined predicates, incorrect use of directives, missing declarations, ...
Pop-up documentation
Predicate documentation is parsed on-the-fly and shown when the mouse is hovering over a call. This works for both built-in and user-defined predicates.
Open Definition
Clicking on a called predicate can bring up its source code.
Call Hierarchy
Show callers and other references to a predicate or file.
Show profiling data
Source Code Coverage
Show source code coverage, both as margin annotations and in various tabular forms.
Call Hierarchy
Show callers and other references to a predicate or file.
File outline
The predicates in a file are shown in an outline. They can be alphabetically sorted and non-exported predicates can be hidden from the outline.
Variable Bindings in Debugger
The debugger shows the names and values of variables.
Debugger Backtrace
Backtrace is shown and there are buttons for common debugger actions (Step Over, Step Out, Redo, ...).
Source Code Debugging
Source-linked debugging. Works also for code that has no recorded source info, like the SICStus library.
Prolog Toplevel
The ordinary toplevel is still available, including the traditional debugger interface.
Attach to embedded code
SPIDER can attach to a SICStus runtime embedded in some other program.
Works With Existing Code
No need to reorganize your code, SPIDER can work with your existing folder structure.
Powered by Eclipse
Eclipse provides many features for free, like support for other programming languages, revision control, and much more.

Some of these features can be seen in the following screen shot.
