PDT is a free Prolog IDE provided as a plug-in for the Eclipse IDE that's available at:


PDT is being extended with Logtalk support. The default settings file contains some example settings for Logtalk development using PDT.

PDT currently requires a recent version of SWI-Prolog. It's possible to start up Logtalk automatically by configuring PDT runtime preferences. The configuration depends on the operating-system.

After installing Logtalk and setting the LOGTALKHOME and LOGTALKUSER environment variables, open Eclipse preferences, select PDT runtime preferences, and enter the following configuration data for the SWI-Prolog executable and for the extra environment variables (change the paths to match your SWI-Prolog and Logtalk installations and your home directory):


/Users/pmoura/bin/swipl -s /opt/local/share/logtalk/integration/logtalk_swi.pl DISPLAY=:0.0, HOME=/Users/pmoura, LOGTALKHOME=/opt/local/share/logtalk, LOGTALKUSER=/Users/pmoura/logtalk

Notes: full paths should be used; no quotes should be used.


cmd.exe /c start "cmdwindow" /min "C:\Program Files\pl\bin\swipl-win.exe" -s "%LOGTALKHOME%\integration\logtalk_swi.pl"


/usr/bin/swipl -L4m -G4m -T4m -s /usr/share/logtalk/integration/logtalk_swi.pl LOGTALKHOME=/usr/share/logtalk, LOGTALKUSER=/home/pmoura/logtalk

Notes: full paths should be used; no quotes should be used.

Logtalk 2.43.0 or a later version with the source_data compiler flag turned on is necessary for using PDT. Currently supported PDT features include consulting Logtalk source files, the source file outline (which requires the source code to be consulted first), and selecting a goal and searching for all declarations and definitions (you must select the whole goal and control-click on the selection).
