Also fix some precedence issues.
2017-02-24Modify Prolog parser to produce ASTs instead of parse treesTimotej Lazar

2016-04-08Prolog: use A,B,C,… for normalized variable namesTimotej Lazar
This is somewhat more readable than A0,A1,A2,….

To keep compatibility with existing test / hint functions.
2016-02-23Prolog engine: allow lists predicates in sandboxTimotej Lazar
2016-02-17prolog.engine: use a urllib3 HTTP connection poolTimotej Lazar
Opening large numbers of single-shot requests caused local port exhaustion due to TIME_WAIT.

2016-01-04Add function to find predicates used by a Prolog programTimotej Lazar
2015-12-11Rename a functionTimotej Lazar
2015-12-11Use a more general method for extracting editsTimotej Lazar
This is a large overhaul of monkey code. Before, only edits within individual lines were tracked, which required a Prolog-specific method for splitting a program into a list of lines for every rule. In this version, modifications can be tracked within arbitrary code ranges. Ranges to be tracked are determined by selecting "interesting" subtrees in the AST of the starting code version. The new method is simpler, less language-dependent and easier to extend. The downside is that a program must be syntactically correct before we can attempt to fix it (the previous approach could handle programs with syntax errors in some cases). This commit also integrates a call to monkey.fix in prolog_session.hint, by running it if no other hint is found.
2015-12-10Support Tree objects in python.util.stringifyTimotej Lazar

2015-12-10Sort token list for Prolog parserTimotej Lazar
Ensures the cached version of parsetab.py is used.
2015-12-10Fix a parser bugTimotej Lazar

2015-11-27Fix: response on /pengine/destroy_all is just "ok"Timotej Lazar
2015-11-18Disable predicate autoloading in Prolog engineTimotej Lazar
So that for example append/3 and member/2 are not accessible to users when solving conc/3 and memb/2.
2015-11-18Fix test code in prolog.engineTimotej Lazar
2015-11-04Fix prolog.engine.check_answersTimotej Lazar
Variables not specified in the set of expected answers are now ignored.
2015-10-05Add the prolog runner to be used for daemonisation in init scripts.Aleš Smodiš
2015-09-17Replace prolog.engine.ask_all with check_answersTimotej Lazar
When testing a program we can stop searching for new solutions after we have received a wrong one.
2015-09-10Update prolog engine (sasha's aux functions for prolog hint testing added).Aleksander Sadikov
2015-08-30Replaced localhost with 127.0.0.1Aleksander Sadikov
Windows takes a while to resolve the above.

2015-08-27Strip trailing periods from Prolog queriesTimotej Lazar
2015-08-27Replace prolog.engine.run with ask_allTimotej Lazar

2015-08-27Fix a typo and add a commentTimotej Lazar
2015-08-26Use /destroy_all to abort and destroy penginesTimotej Lazar
