Prolog DCG "distilled" - Part 2




Welcome back to this 2 Part introduction to DCGs, more posts are to come.

Jumping straight on where Part 1 was left, and in order to understand the inner workings of the conc_sep predicate, one can now:

- activate the graphical debugger in the swipl-win tool menu
- prepend a "trace, " before the actual DCG test run:

?- trace, test_conc_sep_3(Bird1, Bird2).

from that point on my colleague Dr Scratch is taking over and presenting you the steps involved:

enjoy !

A possible solution for using the janus interface on MacOS with docker

 Experimenting with the Janus module on docker Janus is a new development that comes with swi-prolog version 9:  janus documentation Having attempted to run the example in the above link, I tried the following steps to install and use the spacy python package: pip install spacy docker run -it --rm --network host -v $(pwd):/opt/janus\ -v /path/to/python3.11/site-packages:/opt/python\ swipl ?- consult('/opt/janus/test_janus.pl'). ?- py_add_lib_dir('/opt/python'). ?- noun("This is a sentence.", Noun). ERROR: Python 'ImportError': ERROR: Error importing numpy: you should not try to import numpy from its source directory; please exit the numpy source tree, and relaunch your python interpreter from there.

Meaningful Xml Diffs with SWI-Prolog

Introduction Building on the previous article I wrote on using the SWI Prolog Xpath predicate for analyzing Xml Node Set relationships, I now describe a way to produce a tree oriented diff based on similar techniques. The goal of such a diff is to identify objects of 2 Xml trees which differ by a given sub-node. In a sense is that diff not a fully general diff, as it focuses on 2 or 3 levels: object sub-or-descendant node resp. property when required, property of the sub-or-descendant node specified by the user, within the Xml tree structure. Another important goal of this diff is to be able to accommodate a different ordering of these objects in the Xml structure, which is normally a constraint which most editors or developer tools can’t cope with. In the following sections I will again use a similar fictitious tree example as in the precedent article. Resources for this article Prolog source code and XML examples are available on  [github] ...

Prolog DCG "distilled" - Part 3 - Capturing and assembling textual elements from rules

Image
Capturing and assembling textual elements from rules This article builds on the previous ones, featuring a small parser for Org Mode files. I use the Clocking feature of emacs to capture how long I work on specific tasks.  However from time to time,  I have to aggregate data over several files, on a monthly or yearly basis, and this is where the small tool described here can prove useful. The code and tests for this article may be found [ here ]. One of the tests may be run in SWI-Prolog with those steps:                ?- consult('/path/to/clocking_tool.pl').                true.             ?- test_parse_clock(Start, End, Elapsed).             Start = [2020-2-5, 16:6:0], End = [2020-2-5, 17:26:0], Elapsed = 1:20 ;             false. A version for Tau-Prolog can be found  [he...
