# FIDL scripts
This directory contains scripts used by FIDL contributors. When writing a
script, consider saving it here if there is any chance it could be reused,
including being used as a reference for future scripts. All scripts must be
documented in this file.
## find_nullable_union_fields.py
This script analyzes all `.fidl` files in the fuchsia repository and reports
occurrences of nullable fields in unions.
## fix_rust_exhaustive_tables.sh
This script (1) changes FIDL table initializers to use the functional update
syntax `MyTable { /* ... */, ..MyTable::empty() }`, and (2) changes patterns to
use `MyTable { /* ... */, .. }`. It does this by parsing build errors with awk
and then processing them with a Rust program executed using
[rust-script](https://rust-script.org/).
