A Scopes package contains a metadata file scopes-pkg.slon that
provides a human and machine readable description of the package at a
high level.
The file itself is written in Scopes List Notation (SLN), which is what Scopes itself is written in and is most similar to S-Expressions from Lisps.
Herein, we currently recognize the file extension .slon (Scopes List
Optimized Notation) to disambiguate against the other relatively
common .sln extensions. However, this should be subject to change as
of now.
There is a codified schema for the file format to allow for validation, since there is no, and likely/hopefully will never, be a Scopes language specific package manager that serves as a de facto schema reference.
This is written as a JSON Schema in the
file schemas/json-schemas/scopes-pkg.schema.json.
An example of this file can be found in
examples/wumpus/scopes-pkg.slon.
As an example of an external tool parsing this format check out the python-sln Python library & CLI.
It can be used to dump SLN files
