var docMerge = &base.Command{

UsageLine: "{{.Exec}} config-merge",
|
|
Short: "config merge logic",
|
|
Long: `
|
|
Merging of config files is applied in following commands:
|
|
|
|
{{.Exec}} run -c c1.json -c c2.json ...
|
|
{{.Exec}} test -c c1.yaml -c c2.yaml ...
|
|
{{.Exec}} convert c1.json dir1 ...
|
|
|
|
Support of yaml is implemented by converting yaml to json,
|
|
both merge and load. So we take json as example here.
|
|
|
|
Suppose we have 2 JSON files,
|
|
|
|
The 1st one:
|
|
|
|
{
|
|
"log": {"access": "some_value", "loglevel": "debug"},
|
|
"inbounds": [{"tag": "in-1"}],
|
|
"outbounds": [{"_priority": 100, "tag": "out-1"}],
|
|
"routing": {"rules": [
|
|
{"_tag":"default_route","inboundTag":["in-1"],"outboundTag":"out-1"}
|
|
]}
|
|
}
|
|
|
|
The 2nd one:
|
|
|
|
{
|
|
"log": {"loglevel": "error"},
|
|
"inbounds": [{"tag": "in-2"}],
|
|
"outbounds": [{"_priority": -100, "tag": "out-2"}],
|
|
"routing": {"rules": [
|
|
{"inboundTag":["in-2"],"outboundTag":"out-2"},
|
|
{"_tag":"default_route","inboundTag":["in-1.1"],"outboundTag":"out-1.1"}
|
|
]}
|
|
}
|
|
|
|
Output:
|
|
|
|
{
|
|
// loglevel is overwritten
|
|
"log": {"access": "some_value", "loglevel": "error"},
|
|
"inbounds": [{"tag": "in-1"}, {"tag": "in-2"}],
|
|
"outbounds": [
|
|
{"tag": "out-2"}, // note the order is affected by priority
|
|
{"tag": "out-1"}
|
|
],
|
|
"routing": {"rules": [
|
|
// note 3 rules are merged into 2, and outboundTag is overwritten,
|
|
// because 2 of them has same tag
|
|
{"inboundTag":["in-1","in-1.1"],"outboundTag":"out-1.1"}
|
|
{"inboundTag":["in-2"],"outboundTag":"out-2"}
|
|
]}
|
|
}
|
|
|
|
Explained:
|
|
|
|
- Simple values (string, number, boolean) are overwritten, others are merged
|
|
- Elements with same "tag" (or "_tag") in an array will be merged
|
|
- Add "_priority" property to array elements will help sort the array
