gfu

gfu is go file utils

GFU contains following functions:

GFU

  1. Read file content as slice of strings via ReadAllLines ```go import ( “github.com/wissance/gfu” // other imports )

var lines []string var err error

// some operations …

lines, err = gfu.ReadAllLines(“my_file.txt”, false) if len(lines) > 0 {

} //


2. Read file content as a string via `ReadAllText`:
```go
import (
	"github.com/wissance/gfu"
	// other imports
)

var text string
var err error

// some operations ...

text, err = gfu.ReadAllText("my_file.txt")
  1. Write slice of strings in file via WriteAllLines This Write overwrites existing file, to add some lines without file erasing use AppendAllLines ```go import ( “github.com/wissance/gfu” // other imports )

lines := []string{ “{“, “ "id": 1,”, “ "name": "Michael Ushakov"”, “}”, } file := “write_all_lines_test.txt” err := gfu.WriteAllLines(file, lines, “\n”)

4. Write text in file via `WriteAllText`, this is _boring_ wrap around `os.WriteFile`
```go
import (
	"github.com/wissance/gfu"
	// other imports
)

text := "some text"
var err error

// some operations ...

err = gfu.WriteAllText("my_file.txt", text)
  1. Append lines to existing file AppendAllText, if file doesn’t exist this function create it ```go import ( “github.com/wissance/gfu” // other imports )

lines := []string{ “{“, “ "id": 2,”, “ "name": "Alex Petrov"”, “}”, } file := “write_all_lines_test.txt” err := gfu.AppendAllLines(file, lines, “\n”) ```
