How best to organize & modularize project code files?

[dcnorris]

I'd like to start using module/2 to better define dependencies between various code files in my project. How can I coax use_module(library(_)) to find modules located in a project (sub)directory? It looks to me as if neither library_directory/2 (deprecated?) nor file_search_path/2 is implemented.

Have a look at tabling.pl for examples of what you want.

Thanks, Mark. I see code like the following up top of tabling.pl, pointing to a tabling subdirectory of scryer-prolog/src/lib/. Because I'm developing my Prolog code as part of an R package, however, I'd like to have library(_) find files under the exec/ dir of my package. Does Scryer have a library 'search path' I can append to?

:- use_module(library(tabling/double_linked_list)).
:- use_module(library(tabling/table_data_structure)).
:- use_module(library(tabling/batched_worklist)).
:- use_module(library(tabling/global_worklist)).
:- use_module(library(tabling/table_link_manager)).
:- use_module(library(tabling/wrapper)).

I'd accept connection with #701 as an 'answer'.

By doing

(setq ediprolog-temp-file "./ediprolog-temp")

in my project directory, I'm able to

:- use_module(modulename).

in the usual way.
Thanks to @triska for this suggestion.
