"""Create/modify files recording Cylc install config options.
Creates a new config based on CLI options and writes it to the workflow
install location as ``rose-suite-cylc-install.conf``.
If ``rose-suite-cylc-install.conf`` already exists over-writes changed
items, except for ``!opts=`` which is merged and simplified.
If ``!opts=`` have been changed these are appended to those that have
been written in the installed ``rose-suite.conf``.
Args:
srcdir (pathlib.Path):
Used to check whether the source directory contains a rose config.
opts:
Cylc option parser object - we want to extract the following
values:
- opt_conf_keys (list or str):
Equivelent of ``rose suite-run --option KEY``
- defines (list of str):
Equivelent of ``rose suite-run --define KEY=VAL``
- suite_defines (list of str):
Equivelent of ``rose suite-run --define-suite KEY=VAL``
rundir (pathlib.Path):
Path to dump the rose-suite-cylc-conf
Returns:
cli_config - Config Node which has been dumped to
``rose-suite-cylc-install.conf``.
rose_suite_conf['opts'] - Opts section of the config node dumped to
installed ``rose-suite.conf``.
