# Reads multiple individual benchmark reports produced by scripts from
# test/externalTests/ from standard input and creates a combined report.
#
# Usage:
# <script name>.sh < <CONCATENATED_REPORTS>
#
# CONCATENATED_REPORTS: JSON report files concatenated into a single stream (e.g. using cat).
#
# Example:
# cat reports/externalTests/benchmark-*.json | <script name>.sh

# We expect a series of dicts of the form {"<project>": {"<preset>": {...}}}.
# Unfortunately jq's built-in `add` filter can't handle nested dicts and
# would just overwrite values sharing a project name instead of merging them.
# This is done by first grouping the dicts into an array of the form
# [
# [{"key": "<project1>", "value": {"<preset1>": {...}}}, {"key": "<project1>", "value": {"<preset2>": {...}}, ...],
# [{"key": "<project2>", "value": {"<preset1>": {...}}}, {"key": "<project2>", "value": {"<preset2>": {...}}, ...],
# ...
# ]
# and then using reduce() on each group sharing the same project name to convert it into a
# dict having preset names as keys.
