/*
|
|
* This program exposes the C API of the configuration mechanism
|
|
* as a set of simple commands in order to facilitate testing.
|
|
*
|
|
* Reads stdin and prints result of command to stdout:
|
|
*
|
|
* get_value -> prints the value with highest priority for the entered key
|
|
*
|
|
* get_value_multi -> prints all values for the entered key in increasing order
|
|
* of priority
|
|
*
|
|
* get -> print return value for the entered key
|
|
*
|
|
* get_int -> print integer value for the entered key or die
|
|
*
|
|
* get_bool -> print bool value for the entered key or die
|
|
*
|
|
* get_string -> print string value for the entered key or die
|
|
*
|
|
* configset_get_value -> returns value with the highest priority for the entered key
|
|
* from a config_set constructed from files entered as arguments.
|
|
*
|
|
* configset_get_value_multi -> returns value_list for the entered key sorted in
|
|
* ascending order of priority from a config_set
|
|
* constructed from files entered as arguments.
|
|
*
|
|
* iterate -> iterate over all values using git_config(), and print some
|
|
* data for each
|
|
*
|
|
* git_config_int -> iterate over all values using git_config() and print the
|
|
* integer value for the entered key or die
|
|
*
|
|
* Examples:
|
|
*
|
|
* To print the value with highest priority for key "foo.bAr Baz.rock":
|
|
* test-tool config get_value "foo.bAr Baz.rock"
|
|
*
