# NOTE:
# This is a composite script to use from a composite GitHub action.
#
# NOTE:
#
# Yaml specific system variables (to use):
#
# * YQ_CMDLINE_READ
# * YQ_CMDLINE_READ_AS_YAML
# * YQ_CMDLINE_WRITE
# * YQ_DIFF_ALL_CMDLINE
# * YQ_DIFF_NO_BLANKS_CMDLINE
# * YQ_PATCH_DIFF_CMDLINE
#
# Yaml specific user variables (to set):
#
# * ENABLE_YAML_PRINT_AFTER_EDIT
# * ENABLE_YAML_PRINT_AFTER_PATCH # has priority over `ENABLE_YAML_PRINT_AFTER_EDIT` variable
# * ENABLE_YAML_DIFF_PRINT_AFTER_EDIT
# * ENABLE_YAML_DIFF_PRINT_BEFORE_PATCH # has priority over `ENABLE_YAML_DIFF_PRINT_AFTER_EDIT` variable
# * ENABLE_YAML_PATCH_DIFF_PAUSE_MODE
#
# CAUTION:
#
# The `yq` command lines designed to be able to run independently to these `yq` implementations:
#
# * https://github.com/kislyuk/yq - a `jq` wrapper (default Cygwin distribution)
# * https://github.com/mikefarah/yq - Go implementation (default Ubuntu 20.04 distribution)
#
# Usage example:
#
# >
# yq_edit "<prefix-name>" "<suffix-name>" "<input-yaml>" "$TEMP_DIR/<output-yaml-edited>" \
# <list-of-yq-eval-strings> && \
# yq_diff "$TEMP_DIR/<output-yaml-edited>" "<input-yaml>" "$TEMP_DIR/<output-diff-edited>" && \
# yq_restore_edited_uniform_diff "$TEMP_DIR/<output-diff-edited>" "$TEMP_DIR/<output-diff-edited-restored>" && \
# yq_patch "$TEMP_DIR/<output-yaml-edited>" "$TEMP_DIR/<output-diff-edited-restored>" "$TEMP_DIR/<output-yaml-edited-restored>" "<output-yaml>" ["<input-yaml>"]
#
# , where:
#
# <prefix-name> - prefix name part for files in the temporary directory
# <suffix-name> - suffix name part for files in the temporary directory
#
# <input-yaml> - input yaml file path
# <output-yaml> - output yaml file path
#
# <output-yaml-edited> - output file name of edited yaml
# <output-diff-edited> - output file name of difference file generated from edited yaml
# <output-diff-edited-restored> - output file name of restored difference file generated from original difference file
# <output-yaml-edited-restored> - output file name of restored yaml file stored as intermediate temporary file
#
# Script both for execution and inclusion.
