| 2021-07-27 | remove clausenr from terms, and put it into goals instead. Next up is ↵HEADfront | Peter Mikkelsen | |
| implementing the control constructs in C, since they misbehave right now due to the new changes | |||
| 2021-07-27 | Don't use strings to identify vars, use numbers | Peter Mikkelsen | |
| 2021-07-23 | Simplify parsing a bit, and make sure the prolog loader calls read_term with ↵ | Peter Mikkelsen | |
| the correct module to pick up the correct operators | |||
| 2021-07-22 | Big commit changing the way the system is loaded at startup. | Peter Mikkelsen | |
| 1) The loader and system modules are loaded by the C directly into the user module 2) The system module is then loaded with the loader from the user module 3) The loader module is then loaded with the loader from the user module 4) The repl is then loaded with the loader from the loader module 5) The user module is cleared | |||
| 2021-07-19 | More work on streams | Peter Mikkelsen | |
| 2021-07-16 | Implement a bit more of prolog flag predicates set_prolog_flag/2 and ↵ | Peter Mikkelsen | |
| current_prolog_flag/2 | |||
| 2021-07-16 | Replace the C repl with one written in prolog :) | Peter Mikkelsen | |
| 2021-07-16 | Add character input/output | Peter Mikkelsen | |
| 2021-07-16 | Make operators local to each module, and implement some more correct ↵ | Peter Mikkelsen | |
| prettyprint code, used by write_term | |||
| 2021-07-15 | Make read_term understand the three read options: | Peter Mikkelsen | |
| variables(Vars), variable_names(VarNames), singletons(Singles) as required per the ISO standard | |||
| 2021-07-09 | Add asserta/1, assertz/1, retract/1, abolish/1 (and retract_one/1, which is ↵ | Peter Mikkelsen | |
| retract/1 but doesn't backtrack) | |||
| 2021-07-08 | Add current_predicate/1 builtin | Peter Mikkelsen | |
| 2021-07-08 | Add a mark-sweep garbage collector | Peter Mikkelsen | |
| 2021-07-08 | Add clause/2 predicate | Peter Mikkelsen | |
| 2021-07-08 | Implement the full arithmetic part of the ISO spec. | Peter Mikkelsen | |
| 2021-07-07 | Make '=..'/2 work according to spec. Introduce types.c for functions which ↵ | Peter Mikkelsen | |
| tells us something about term types. Should be used a lot more instead of explicitly looking into terms->tag everywhere | |||
| 2021-07-06 | Store the calling module in each goal, and fix a bug where unification could ↵ | Peter Mikkelsen | |
| leave behind some bindings even though the unification failed. | |||
| 2021-07-05 | Turn integers and floats into seperate term types | Peter Mikkelsen | |
| 2021-07-05 | First step on modules. Still very very rough. | Peter Mikkelsen | |
| 2021-07-03 | Add one global choicestack so we don't need to pass it around | Peter Mikkelsen | |
| 2021-07-03 | Start adding support for read_term and write_term | Peter Mikkelsen | |
| 2021-07-02 | Start work on input/output streams | Peter Mikkelsen | |
| 2021-07-02 | Begin work on set_prolog_flag/2 and current_prolog_flag/2 | Peter Mikkelsen | |
| 2021-07-02 | Remove strings, and add a (currently not changable) flag 'double_quotes' ↵ | Peter Mikkelsen | |
| which defines how double quoted strings are stored. | |||
| 2021-07-01 | Add exceptions :) implement catch/3 and throw/1 | Peter Mikkelsen | |
| 2021-06-30 | Allow the repl to backtrack to give alternative results | Peter Mikkelsen | |
| 2021-06-30 | Add comparison predicates | Peter Mikkelsen | |
| 2021-06-30 | Add builtins for typetests | Peter Mikkelsen | |
| 2021-06-30 | Add support for builtins, and implement true/0, fail/0, call/1, and !/0 builtins | Peter Mikkelsen | |
| 2021-06-30 | Add a basic repl | Peter Mikkelsen | |
| 2021-06-30 | Add backtracking to the evaluator. This means we have to keep track of ↵ | Peter Mikkelsen | |
| choicepoints which is implemented the easy but wasteful way for now. I have also added a number which is used to differentiate variables from different application of the clauses. | |||
| 2021-06-30 | Start work on an evaluator. For now it knows how to unify but doesn't know ↵ | Peter Mikkelsen | |
| how to handle builtin predicates or how to backtrack | |||
| 2021-06-29 | Make parse return a list of clauses. Also pretty print the entire list of ↵ | Peter Mikkelsen | |
| clauses. | |||
| 2021-06-29 | Add a term parser. | Peter Mikkelsen | |
| 2021-06-28 | Initial commit. Start working on a new prolog implementation for 9front, now ↵ | Peter Mikkelsen | |
| that I at least have a better understanding of what goes into a compiler :) | |||
| index : pprolog | ||
| A new prolog interpreter for Plan 9. Replaces the old pprolog project. |
