Overview

Package reload offers lightweight automatic reloading of running processes.

After initialisation with reload.Do() any changes to the binary will restart the process.

Example:

go func() {
    err := reload.Do(log.Printf)
    if err != nil {
        panic(err)
    }
}()

A list of additional directories to watch can be added:

go func() {
    err := reload.Do(log.Printf, reload.Dir("tpl", reloadTpl)
    if err != nil {
        panic(err)
    }
}()

Note that this package won't prevent race conditions (e.g. when assigning to a global templates variable). You'll need to use sync.RWMutex yourself.

Constants

const (
	LogLevelNone int = iota
	LogLevelInfo
	LogLevelWarn
	LogLevelError
	LogLevelDebug
)
const (
	PEM_SIG = "--BEGIN "
)

func BuildDetails

func BuildDetails() string

func Cmd

func Cmd()

func Dir

func Dir(path string, cb func()) dir

Dir is an additional directory to watch for changes. Directories are watched non-recursively.

The second argument is the callback that to run when the directory changes. Use reload.ReExec(servConf) to restart the process.

func Do

func Do(servConf *ServConfig, log func(string, ...interface{}), additional ...dir) error

Do reload the current process when its binary changes.

The log function is used to display an informational startup message and errors. It works well with e.g. the standard log package or Logrus.

The error return will only return initialisation errors. Once initialized it will use the log function to print errors, rather than return.

func GetConfigName

func GetConfigName() string

func NewCSVSource

func NewCSVSource(filename string, sep rune) (*csvSource, error)

func ReExec

func ReExec(servConf *ServConfig) func()

Exec replaces the current process with a new copy of itself.

type Action

type Action struct {
	Name     string
	SQL      string
	AuthName string `mapstructure:"auth_name"`
}

Action struct contains config values for a Super Graph service action

type Auth

type Auth struct {
	Name          string
	Type          string
	Cookie        string
	CredsInHeader bool `mapstructure:"creds_in_header"`

	}
}

Auth struct contains authentication related config values used by the Super Graph service

type Config

type Config struct {
	Core `mapstructure:",squash"`
	Serv `mapstructure:",squash"`
	// contains filtered or unexported fields
}

Config struct holds the Super Graph config values

func ReadInConfig

func ReadInConfig(configFile string) (*Config, error)

ReadInConfig function reads in the config file for the environment specified in the GO_ENV environment variable. This is the best way to create a new Super Graph config.

type Core

type Core = core.Config

type ErrorLineExtract

type ErrorLineExtract struct {
	LineNum   int    // Line number starting with 1
	ColumnNum int    // Column number starting with 1
	Text      string // Text of the line without a new line character.
}

func ExtractErrorLine

func ExtractErrorLine(source string, position int) (ErrorLineExtract, error)

ExtractErrorLine takes source and character position extracts the line number, column number, and the line of text.

The first character is position 1.
