Marshal processes a file in data directory and generates ListInfo for it.

isEmpty checks if the rule that has been trimmed out spaces is empty

Flatten flattens the rules in a file that have "include" syntax in data directory, and adds those need-to-included rules into it. This feature support

FlattenAndGenUniqueDomainList flattens the included lists and generates a domain trie for each file in data directory to make the items of domain type

GetDataDir returns the path to the "data" directory used to generate lists. Usage order: 1. The datapath that user set when running the program 2. The

GetGOPATH returns GOPATH environment variable as a string. It will NOT be empty.

GetRuntimeEnv returns the value of runtime environment variable, that is set by running following command: `go env -w key=value`.

Insert inserts a domain rule string into the domain trie and return whether is inserted successfully or not.

NewDomainTrie creates and returns a new domain trie.

NewListInfo return a ListInfo

ProcessList processes each line of every single file in the data directory and generates a ListInfo of each file.

ToGFWList converts router.GeoSite to GFWList format.

ToGeoSite converts every ListInfo into a router.GeoSite structure. It also excludes rules with certain attributes in certain files that user specified

ToPlainText convert router.GeoSite structure to plaintext format.

ToProto generates a router.GeoSite for each file in data directory and returns a router.GeoSiteList

classifyRule classifies a single rule and write into *ListInfo

envFile returns the name of the Go environment configuration file. Copy from https://github.com/golang/go/blob/c4f2a9788a7be04daf931ac54382fbe2cb75493

parseRule parses a single rule

removeComment removes comments in the rule

ToGFWList returns the content of the list to be generated into GFWList format that user wants in bytes format.

ToPlainText returns a map of exported lists that user wants and the contents of them in byte format.
