# Regenerates typescript files with schema and sql for grist documents.
# This needs to run whenever the document schema is changed in the data
# engine, maintained in python code. It propagates the schema information
# to a typescript file, and updates SQL code for initializing new documents.
#
# To preview what it will do, call as:
#   buildtools/update_schema.sh schema.ts sql.ts
# This will put schema.ts and sql.ts files in your working directory.
# Run without any arguments to modify application files.
#   buildtools/update_schema.sh
# (you can see the differences with git diff if in a git repository).
