Native predicates for ichiban/prolog.

Prolog

Filesystem predicates use io/fs.FS.

Built-in replacements

• consult/1

library(files)

These predicates are intended to be compatible with Scryer Prolog's library(files). These use strings (lists of characters) for filenames.

• directory_files/2
• directory_exists/1
• file_exists/1

Lists

• is_list/1
• atomic_list_concat/3

Atoms

• downcase_atom/2
• upcase_atom/2

Package taujson

These predicates are intended to be compatible with Tau Prolog's library(js). They are peculiar predicates that use opaque native objects for JSON conversion.

• json_atom/2
• json_prolog/2

Graduated

• between/3 made it into ichiban/prolog in v0.9.0!

Go

Package chars provides some convenience functions for working with Prolog strings.
