| # List Prolog Interpreter | |
| List Prolog Interpreter (LPI) makes it easier to generate List Prolog programs. It works by interpreting different versions of Prolog that are in a list format. Using an algorithm that was written in SWI-Prolog, it easily parses and runs List Prolog code. | |
| # Getting Started | |
| Please read the following instructions on how to install the project on your computer for writing code. | |
| # Prerequisites | |
| * Please download and install SWI-Prolog for your machine at `https://www.swi-prolog.org/build/`. | |
| * You may need to install gawk using Homebrew. | |
| * Install <a href="https://github.com/soimort/translate-shell">Translation Shell</a> on Mac, etc. | |
| Change line in | |
| ``` | |
| culturaltranslationtool/ctt2.pl | |
| trans_location("../../../gawk/trans"). | |
| ``` | |
| to correct location of <a href="https://github.com/soimort/translate-shell">trans</a>. | |
| # 1. Install manually | |
| Download <a href="http://github.com/luciangreen/listprologinterpreter/">this repository</a>, the <a href="https://github.com/luciangreen/Languages"> Languages repository</a> (which enables List Prolog Interpreter to be run in different languages), <a href="https://github.com/luciangreen/SSI">SSI</a> and <a href="https://github.com/luciangreen/culturaltranslationtool">Cultural Translation Tool</a>. | |
| # 2. Or Install from List Prolog Package Manager (LPPM) | |
| * Download the <a href="https://github.com/luciangreen/List-Prolog-Package-Manager">LPPM Repository</a>: | |
| ``` | |
| mkdir GitHub | |
| cd GitHub/ | |
| git clone https://github.com/luciangreen/List-Prolog-Package-Manager.git | |
| cd List-Prolog-Package-Manager | |
| swipl | |
| ['lppm']. | |
| lppm_install("luciangreen","listprologinterpreter"). | |
| halt | |
| ``` | |
| # Running | |
| * In Shell: | |
| `cd listprologinterpreter` | |
| `swipl` | |
| `['listprolog'].` | |
| * Running the tests | |
| To run all tests, enter: | |
| `test(off,NTotal,Score).` | |
| To run a specific test: | |
| `test1(off,TestNumber,Passed).` | |
| where TestNumber is the test number from <a href="lpiverify4.pl">lpiverify4.pl</a>. | |
| Example of an end to end test | |
| The query `test1(Debug,1,Passed).` | |
| where `Debug (trace)=off` | |
| tests the following predicate: | |
| ``` | |
| test(1,[[n,function],[1,1,[v,c]]], | |
| [ | |
| [[n,function],[[v,a],[v,b],[v,c]],":-", | |
| [ | |
| [[n,+],[[v,a],[v,b],[v,c]]] | |
| ] | |
| ] | |
| ] | |
| ,[[[[v,c], 2]]]). | |
| ``` | |
| This query contains the query tested, the predicate and the required result. | |
| Also, the query `test1(off,7,Passed).` | |
| ``` | |
| test(7,[[n,reverse],[[1,2,3],[],[v,l]]], | |
| [ | |
| [[n,reverse],[[],[v,l],[v,l]]], | |
| [[n,reverse],[[v,l],[v,m],[v,n]],":-", | |
| [ [[n,head],[[v,l],[v,h]]], | |
| [[n,tail],[[v,l],[v,t]]], | |
| [[n,wrap],[[v,h],[v,h1]]], | |
| [[n,append],[[v,h1],[v,m],[v,o]]], | |
| [[n,reverse],[[v,t],[v,o],[v,n]]] | |
| ] | |
| ] | |
| ],[[[[v,l], [3, 2, 1]]]]). | |
| ``` | |
| tests the reverse predicate. | |
| To run all tests (main, types, open and open types) in any language: | |
| ``` | |
| test_all00("en",off,NTotal,Score). | |
| test_all00("en2",off,NTotal,Score). | |
| ``` | |
| where "en2" is an English language with e.g. `"concatenate strings"` instead of `stringconcat` ("en", or see available <a href="https://github.com/soimort/translate-shell">language codes</a> - see the <a href="https://github.com/luciangreen/Languages"> Languages repository</a> for instructions about how to install different languages). | |
| * Note 1: drag and drop contents of `test_open_and_types_open_data/` into an empty file in BBEdit (Mac) to copy and paste into Terminal for tests with input. | |
| To run a test from one of main, types, open or open types, run one of: | |
| ``` | |
| test_all01(test, 4,"en2",off,1,Passed). | |
| test_all01(test_types_cases,6,"en2",off,1,Passed). | |
| test_all01(testopen_cases, 3,"en2",off,1,Passed). | |
| test_all01(test_open_types, 5,"en2",off,1,Passed). | |
| ``` | |
| where 1 is replaced with the test number from | |
| * <a href="https://github.com/luciangreen/listprologinterpreter/blob/master/lpiverify4.pl">lpiverify4.pl</a> | |
| * <a href="https://github.com/luciangreen/listprologinterpreter/blob/master/lpiverify4_types.pl">lpiverify4_types.pl</a> | |

| * <a href="https://github.com/luciangreen/listprologinterpreter/blob/master/lpiverify4_open_types.pl">lpiverify4_open_types.pl</a> | |
| respectively. | |
| * Run Prolog tests: | |
| ``` | |
| ['lpiverify_pl.pl]. | |
| test_pl1(off,A,B). | |
| ``` | |
| * See note 1 above. | |
| To run all tests (main, types, open and open types) back-translating to and from any language: | |
| ``` | |
| test_all_bt00("en2",off,NTotal,Score). | |
| ``` | |
| To run a test from one of main, types, open or open types, run one of: | |
| ``` | |
| test_all_bt01(test, 4,"en2",off,1,Passed). | |
| test_all_bt01(test_types_cases,6,"en2",off,1,Passed). | |
| test_all_bt01(testopen_cases, 3,"en2",off,1,Passed). | |
| test_all_bt01(test_open_types, 5,"en2",off,1,Passed). | |
| ``` | |
| where 1 is replaced with the test number from | |
| * <a href="https://github.com/luciangreen/listprologinterpreter/blob/master/lpiverify4.pl">lpiverify4.pl</a> | |
| * <a href="https://github.com/luciangreen/listprologinterpreter/blob/master/lpiverify4_types.pl">lpiverify4_types.pl</a> | |

| # LPI API | |
| * To run LPI on a Prolog server: | |
| * Move `lpi-api.pl` to the root (`/username/` or `~` on a server) of your machine. | |
| * Re-enter the paths to your Prolog files in it. | |
| * Enter `[lpi-api.pl]` in SWI-Prolog and `server(8000).`. | |
| * On a local host access the algorithm at `http://127.0.0.1:8000` and replace 127.0.0.1 with your server address. | |

| # Occurs Check | |
| * To return false if an equals4 variable is in terms of itself, for example: | |
| ``` | |
| occurs_check([v,a],[[v,a]]). | |
| false. | |
| ``` | |
| * then enter `turn_occurs_check(on).`. To return `true.` above, indicating any occurrences have been ignored, enter `turn_occurs_check(off).` (the default). | |
