# generate-j2-data.py - Generates a JSON file containing all substitutions
# defined by myst_substitutions within "conf.py", printing the result to
# STDOUT. This data can be consumed by jinjanator/j2cli to provide context to
# templates and avoid the complexity of using MyST to perform the substitions
# later (which would require double-escaping Jinja expressions).
#

import json

# Pull in the contents of the Sphinx conf.py
exec(compile(open('src/conf.py', 'rb').read(), 'src/conf.py', 'exec'))

# Dump all MyST Parser substitutions as JSON for consumption by
# jinjanator/j2cli
print(json.dumps(myst_substitutions))
