3 # What is it? | |
4 | |
5 Brachylog is a declarative logic programming language much like Prolog. Brachylog is designed to be much terser than Prolog, while retaining some readability. | |
6 | |
7 Currently in development. | |
8 | |
9 Brachylog uses [SWI-Prolog](http://www.swi-prolog.org/) as Prolog engine. | |
10 | |
11 ## How do I use this? | |
12 | |
13 ### Documentation | |
14 | |
15 Check out [Brachylog's Wiki](https://github.com/JCumin/Brachylog/wiki) if you want to learn how to write programs in this language. | |
16 | |
17 You may want to watch this [**short video introduction to Brachylog**](https://www.youtube.com/watch?v=XYVhZ-MFcUs). | |
18 | |
19 ### Try it online! | |
20 | |
21 You can try out Brachylog on [Try it online!](https://tio.run/nexus/brachylog2), thanks to @DennisMitchell. | |
22 | |
23 ### Brachylog language bar | |
24 | |
25 [You can find here](https://abrudz.github.io/lb/brachylog) the Brachylog language bar which gives you access to all symbols used in Brachylog on any webpage (by clicking on the symbols or by inputing shortcuts), thanks to @abrudz. | |
26 | |
27 ### The interpreter | |
28 | |
29 Brachylog's interpreter is entirely written in Prolog. Therefore, installing [SWI-Prolog](http://www.swi-prolog.org/) (version 7 and up) is mandatory to use Brachylog (We do not guarantee that Brachylog's interpreter will be compatible with any other Prolog implementation). | |
30 | |
31 To run Brachylog's interpreter, start SWI-Prolog's interpreter inside the `src` directory available in this repository, and consult the file `brachylog.pl` (`consult(brachylog).`). Alternatively, you can run the interpreter with: | |
32 | |
33 $ swipl src/brachylog.pl | |
34 | |
35 You can then run Brachylog programs using different predicates: | |
36 | |
37 - `run_from_file(FileName, Input, Output)`: `FileName` is an atom (i.e. between single quotes `'`) representing the file containing your Brachylog code. For example: `run_from_file('code.brachylog',"Test Input",Z)`. | |
38 | |
39 - `run_from_atom(Code, Input, Output)`: `Code` is an atom (i.e. between single quotes `'`) containing your Brachylog code. For example: `run_from_atom('∧"Hello, World!"w',_,_)`. Note that you will have to escape certain characters in `Code`. | |
40 | |
41 - `run(Input, Output)`: This will run a Brachylog program that has already been transpiled to Prolog using either of the two previous predicates. More precisely, this will query `brachylog_main/2` in the file `compiled_brachylog.pl`. | |
42 | |
43 The first two predicates will transpile your Brachylog program into Prolog, subsequently generating a file called `compiled_brachylog.pl` in the same directory that contains `brachylog.pl`. The three run predicates will then consult it and query `brachylog_main/3`. | |
44 | |
45 Note that the first two run predicates also exist with either no `Output` argument, or with no `Input` nor `Output` argument, if necessary. For example, `run_from_file('code.brachylog')` is equivalent to `run_from_file('code.brachylog', _, _)`. | |
