Dear SWI-Prolog user, Version 9.3.34 is ready for download. Almost all changes are bugfixes and enhancements to the development environment and tools. Notably Commandline history handling is simplified a lot by removing a lot of old code and building on top of the enhanced libedit extension…

[image] jan: MODIFIED: Commandline history handling. Probably not intended. When I started swipl in a directory that had history already, it started counting at 101 $ swipl Welcome to SWI-Prolog (threaded, 64 bits, version 9.3.34) SWI-Prolog comes with ABSOLUTELY NO WARRANTY. This is free so…

[image] Boris: I can see how that somehow makes sense, I don’t know if it is the desired behaviour. Yes :slight_smile: The default history depth is 100. That means that any other command added to the history causes the oldest to be deleted. When saving, it saves all 100 (or as many there…

[image] jan: If library(editline) is not available, there is no history. Does that mean there is no history on windows?

No. The Windows version comes with library(editline). I had to hack the BSD library a bit. That was done by other people, but those ports relied on a lot of other Unix compatibility libraries. I merely replaced some of the low level I/O routines to call native Windows and hard coded that the …

[image] joseph-vidal-rosset: pcre2 is nevertheless installed.. I do not understand. Is the pcre2 library in the path given to -DCMAKE_FIND_ROOT_PATH=<dir>? Does this work node src/swipl.js ?- use_module(library(pce)). P.s. Please put code in a block guarded by two ``` lines (or indent the …

The instructions still look fine. Works for me. You’ll have to work through the details of he messages to see what could be wrong. A good step is running cmake . in the build dir. That re-runs the configuration. Normally that is pretty silent, but it will print the things that went wron…
