Example:
bundle common globals
{
vars:
"example_data" data => '{ "msg": "Hello from $(this.bundle)" }';
}
bundle agent example_storejson
{
vars:
"example_data" data => '{ "msg": "Hello from $(this.bundle)" }';
# Using storejson with data from remote bundle
# "json_string_zero" -> { "CFEngine 3.16.0"}
# string => storejson( globals.example_data )
# comment => "Unquoted with . (dot) present will cause the parser to error";
"json_string_one" string => storejson( @(globals.example_data) );
"json_string_two" string => storejson( "globals.example_data" );
# Using storejson with data from this bundle
"json_string_three" string => storejson( @(example_storejson.example_data) );
"json_string_four" string => storejson( "example_storejson.example_data");
"json_string_five" string => storejson( example_data );
"json_string_six" string => storejson( "$(this.bundle).example_data");
"json_string_seven" string => storejson( @(example_data) );
reports:
"json_string_one and json_string_two are identical:$(const.n)$(json_string_one)"
if => strcmp( $(json_string_one), $(json_string_two) );
"json_string_{one,two,three,four,five,six,seven} are identical:$(const.n)$(json_string_three)"
if => and(
strcmp( $(json_string_three), $(json_string_four) ),
strcmp( $(json_string_four), $(json_string_five) ),
strcmp( $(json_string_five), $(json_string_six) ),
strcmp( $(json_string_six), $(json_string_seven) )
