Functions ¶
func AsyncMultiWriter ¶ added in v1.7.0
AsyncMultiWriter creates a writer that duplicates its writes to all the provided writers asynchronous
func CreateRandomLenFile ¶
Create a temp file with the requested prefix at the provided dir. File length and contents are random, up to the requested max length.
func GetFileInfo ¶ added in v1.1.2
Get the file info of the file in path. If path points at a symlink and `followSymlink == false`, return the file info of the symlink instead
func IsDirExists ¶ added in v1.1.2
Check if path points at a directory. If path points at a symlink and `followSymlink == false`, function will return `false` regardless of the symlink target
func IsFileSymlink ¶ added in v1.1.2
func IsPathSymlink ¶ added in v1.1.2
func RunCmdOutput ¶ added in v1.0.3
Executes an external process and returns its output. If the returned output is not needed, use the RunCmd function instead , for better performance.
func RunCmdWithOutputParser ¶ added in v1.0.3
func RunCmdWithOutputParser(config CmdConfig, prompt bool, regExpStruct ...*CmdOutputPattern) (stdOut string, errorOut string, exitOk bool, err error)
Executes the command and captures the output. Analyze each line to match the provided regex. Returns the complete stdout output of the command.
Types ¶
type CmdConfig ¶ added in v1.0.3
type CmdConfig interface {
GetCmd() *exec.Cmd
GetEnv() map[string]string
GetStdWriter() io.WriteCloser
GetErrWriter() io.WriteCloser
}
type CmdOutputPattern ¶ added in v1.0.3
type CmdOutputPattern struct {
RegExp *regexp.Regexp
MatchedResults []string
Line string
ExecFunc func(pattern *CmdOutputPattern) (string, error)
}
RegExp - The regexp that the line will be searched upon. MatchedResults - The slice result that was found by the regexp Line - The output line from the external process ExecFunc - The function to execute
type Command ¶ added in v1.3.2
type Command struct {
Executable string
CmdName string
CmdArgs []string
Dir string
StrWriter io.WriteCloser
ErrWriter io.WriteCloser
}
func NewCommand ¶ added in v1.3.2
func (*Command) GetErrWriter ¶ added in v1.3.2
func (config *Command) GetErrWriter() io.WriteCloser
func (*Command) GetStdWriter ¶ added in v1.3.2
func (config *Command) GetStdWriter() io.WriteCloser
