How to save result into txt file

[Mus54]

Hello,
First, thank you for this progam
I see that this program output is displayed on the console.
If we need to save it, we'll need to a datastructure.
I don't konw how to do it because you've used the format/2 predicate to display it.
Could you tell me how to save it without executing command line please ?
Sorry for my bad English
Thank you

Nice idea!

In f6f962e, I have added a pure interface to access the requirements and solutions. For example:

?- timetable_('reqs.xml', Rs, Vs), labeling([ff], Vs).
Rs = [req('1a', anj, anj1, 3)-[3, 9, 16], req('1a', atvz, atvz1, 3)-[4, 10, 25], req('1a', bio, bio1, 2)-[11, 26], req('1a', fiz, fiz1, 2)-[13, 27], req('1a', geo, geo1, 2)-[17, 32], req('1a', kem, kem1, 2)-[18, 33], req('1a', mat, mat1, 5)-[2|...], req(..., ..., ..., ...)-[...|...], ... - ...|...],
Vs = [3, 9, 16, 4, 10, 25, 11, 26, 13|...] .

Please let me know if you have any questions about this.
