# predicates [](https://godoc.org/github.com/guregu/predicates)
`import "github.com/guregu/predicates"`
Native predicates for [ichiban/prolog](https://github.com/ichiban/prolog).
## Prolog
Filesystem predicates use [`io/fs.FS`](https://pkg.go.dev/io/fs).
### Built-in replacements
- `consult/1`
### `library(files)`
These predicates are intended to be compatible with Scryer Prolog's [`library(files)`](https://github.com/mthom/scryer-prolog/blob/master/src/lib/files.pl).
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`](https://godoc.org/github.com/guregu/predicates/taujson)
These predicates are intended to be compatible with Tau Prolog's [`library(js)`](http://tau-prolog.org/documentation#js).
They are peculiar predicates that use opaque native objects for JSON conversion.
- `json_atom/2`
- `json_prolog/2`
### Graduated
- [`between/3`](https://github.com/ichiban/prolog/releases/tag/v0.9.0) made it into ichiban/prolog in `v0.9.0`!
## Go
Package [`chars`](https://godoc.org/github.com/guregu/predicates/chars) provides some convenience functions for working with Prolog strings.
