# JSON merge function: merges multiple JSON files into one output file
|
|
#
|
|
# To use this function in your CMakeLists.txt:
|
|
# include(${CMAKE_SOURCE_DIR}/scripts/CMakeLists.txt)
|
|
#
|
|
# Usage:
|
|
# merge_json_files(
|
|
# OUTPUT <output_file>
|
|
# SOURCES <json_file1> <json_file2> ...
|
|
# [ALLOW_OVERWRITE]
|
|
# [IGNORE_SCHEMA]
|
|
# )
|
|
#
|
|
# Arguments:
|
|
# OUTPUT - Output file path (required)
|
|
# SOURCES - List of JSON files to merge (required)
|
|
# ALLOW_OVERWRITE - Optional flag to allow duplicate keys
|
|
# IGNORE_SCHEMA - Optional flag to ignore "$schema" field in output
|
|
#
|
|
# The function automatically:
|
|
# - Sorts input files alphabetically for consistent results
|
|
# - Tracks dependencies so output is regenerated when inputs change
|
|
# - Errors on duplicate keys unless ALLOW_OVERWRITE is specified
|
|
#
|
|
# Example:
|
|
# merge_json_files(
|
|
# OUTPUT "${CMAKE_CURRENT_BINARY_DIR}/merged.json"
|
|
# SOURCES file1.json file2.json file3.json
|
|
# IGNORE_SCHEMA
|
|
# )
