pathutil

Release Software License Travis Go Report Card GoDoc codecov.io Sourcegraph

Pathutil is I/O utility primary inspired by David Golden's Path::Tiny. It is friendlier to use than path, filepath and provides many of other functions which isn't in core libraries (like Copy for example)

SYNOPSIS
import (
	"fmt"
	"github.com/JaSei/pathutil-go"
)

// creating pathutil objects
dir, _ := pathutil.New("/tmp")
foo, _ := pathutil.New("foo.txt")

subdir, _ := dir.Child("foo")
bar, _ := subdir.Child("bar.txt")

// stringifies as cleaned up path
file, _ := pathutil.New("./foo.txt")
fmt.Println(file) // "foo.txt"

// reading files
guts, _ := file.Slurp()
lines, _ := file.Lines()

// writing files
bar.Spew(data)

// reading directories
children, _ := dir.Children()
for _, child := range children {
}

BREAKING CHANGE 0.3.1 -> 1.0.0

  1. NewTempFile or NewTempDir don't need TempOpt struct

    //0.3.1 default pathutil.NewTempFile(pathutil.TempOpt{}) //0.3.1 custom pathutil.NewTempFile(pathutil.TempOpt{Dir: "/test", Prefix: "pre"})

    //1.0.0 default pathutil.NewTempFile() //1.0.0 custom pathutil.NewTempFile(Dir("/test"), Prefix("pre"))

  2. New method parameter allowed string type or type implements fmt.Stringer interface

    //0.3.1 pathutil.New(otherPath.String(), "test")

    //1.0.0 pathutil.New(otherPath, "test")

This shouldn't be breaking change, but if you use in some code variadic parameter as input of pathutil.New, then can be problem

//0.3.1
func(p ...string) {
	pathutil.New(p...)
}("a", "b")

//1.0.0
func(p ...string) {
	n := make([]interface{}, len(p))
	for i, v := range p {
		n[i] = v
	}
	pathutil.New(n...)
}("a", "b")

  1. There is new (more handfull) crypto API

    //0.3.1 import ( "crypto" "github.com/JaSei/pathutil-go" ) ...

    hash, err := path.Crypto(crypto.SHA256) if err == nil { fmt.Printf("%s\t%s\n", hash.HexSum(), path.String()) }

    //1.0.0 import ( "github.com/JaSei/pathutil-go" ) ...

    hash, err := path.CryptoSha256() if err == nil { fmt.Printf("%s\t%s\n", hash, path.String()) }

This new crypto API return hashutil struct which is more handfull for compare, transformation and next hash manipulation.

Overview

Pathutil is I/O utility primary inspired by David Golden's [Path::Tiny](https://metacpan.org/pod/Path::Tiny). It is friendlier to use than path(https://golang.org/pkg/path/), filepath(https://golang.org/pkg/path/filepath/) and provides many of other functions which isn't in core libraries (like `Copy` for example)

SYNOPSIS 

import (
	"fmt"

BREAKING CHANGE 0.3.1 -> 1.0.0

1. `NewTempFile` or `NewTempDir` don't need TempOpt struct 

//0.3.1 default
pathutil.NewTempFile(pathutil.TempOpt{})
//0.3.1 custom
pathutil.NewTempFile(pathutil.TempOpt{Dir: "/test", Prefix: "pre"})

//1.0.0 default
pathutil.NewTempFile()
//1.0.0 custom
pathutil.NewTempFile(Dir("/test"), Prefix("pre"))

2. `New` method parameter allowed `string` type or type implements `fmt.Stringer` interface 

//0.3.1
pathutil.New(otherPath.String(), "test")

//1.0.0
pathutil.New(otherPath, "test")

This shouldn't be breaking change, but if you use in some code variadic parameter as input of `pathutil.New`, then can be problem 

//0.3.1
func(p ...string) {
	pathutil.New(p...)
}("a", "b")

//1.0.0
func(p ...string) {
	n := make([]interface{}, len(p))
	for i, v := range p {
		n[i] = v
	}
	pathutil.New(n...)
}("a", "b")

3. There is new (more handfull) crypto API 

//0.3.1
import (
	"crypto"
	"github.com/JaSei/pathutil-go"
)
...

hash, err := path.Crypto(crypto.SHA256)
if err == nil {
	fmt.Printf("%s\t%s\n", hash.HexSum(), path.String())
}

//1.0.0
import (
	"github.com/JaSei/pathutil-go"
)
...

hash, err := path.CryptoSha256()
if err == nil {
	fmt.Printf("%s\t%s\n", hash, path.String())
}

This new crypto API return hashutil(github.com/JaSei/hashutil-go) struct which is more handfull for compare, transformation and next hash manipulation.
