julian ![Build Status](https://travis-ci.org/fifth-postulate/julian)

A date and time library for Prolog.

Warning: This is alpha quality software. APIs will change. There are bugs. Use with caution. Time zones are not yet supported and semantics that should account for time zone choose arbitrary, unpredictable behavior.

With that out of the way, the library can do a lot of useful stuff. See the [in-depth tutorial][tutorial] for examples.

Development

Testing

Test are written with the Test Anything Protocol ([TAP][tap]) and use the [fnogatz/tap][pack(tap)] library.

To install the tap pack run

?- pack_install(tap).

Next, the julian pack should be available as a library. One can install from the local installation by running

?- pack_install('file:///home/<path-to-project>/julian').

A TAP test harness should be used to run the tests in this project. To run the t/types.pl test on could execute

prove -v -e 'swipl -q -t main -s' t/types.pl

To run all test one could use

prove -v -e 'swipl -q -t main -s' t/**.pl

Or use `make tests`.
