func OverwriteFile

func Slurp

func Slurp(path string) (*string, error)

Slurp reads an entire file into a string in one operation and returns a pointer to the file's content or an error if any. Similar to `ioutil.ReadFile` but it calls `filepath.Abs` first which cleans the path and resolves relative paths from the working directory.

Note that this is slightly less efficient for zero-length files than `ioutil.Readfile` as it uses the default read buffer size of `bytes.MinRead` internally
