Types

type Config

type Config struct {
	// CacheDir is the main directory for gnmatcher files. It contains
	// bloom filters levenshtein automata trees, key-value stores etc.
	CacheDir string

	// JobsNum is the number of jobs to run in parallel
	JobsNum int

	// MaxEditDist is the maximal allowed edit distance for levenshtein automata.
	// The number cannot exceed 2, default number is 1. The speed of execution
	// slows down dramatically with the MaxEditDist > 1.
	MaxEditDist int

	// PgDB the database name where gnames data is located.
	PgDB string

	// PgHost is a hostname for the PostgreSQL server.
	PgHost string

	// PgPass password to access PostgreSQL server.
	PgPass string

	// PgPort is the port of PostgreSQL server.
	PgPort int

	// PgUser is the user for the database.
	PgUser string

	// WebLogsNsqdTCP provides an address to the NSQ messenger TCP service. If
	// this value is set and valid, the web logs will be published to the NSQ.
	// The option is ignored if `Port` is not set.
	//
	// If WithWebLogs option is set to `false`, but `WebLogsNsqdTCP` is set to a
	// valid URL, the logs will be sent to the NSQ messanging service, but they
	// wil not appear as STRERR output.
	// Example: `127.0.0.1:4150`
	WebLogsNsqdTCP string

	// WithWebLogs flag enables logs when running web-service. This flag is
	// ignored if `Port` value is not set.
	WithWebLogs bool
}
