+
+[![Build Status](https://travis-ci.org/studio-b12/gowebdav.svg?branch=master)](https://travis-ci.org/studio-b12/gowebdav)
+[![GoDoc](https://godoc.org/github.com/studio-b12/gowebdav?status.svg)](https://godoc.org/github.com/studio-b12/gowebdav)
+[![Go Report Card](https://goreportcard.com/badge/github.com/studio-b12/gowebdav)](https://goreportcard.com/report/github.com/studio-b12/gowebdav)
+
+A golang WebDAV client library.
+
+## Main features
+`gowebdav` library allows to perform following actions on the remote WebDAV server:
+* [create path](#create-path-on-a-webdav-server)
+* [get files list](#get-files-list)
+* [download file](#download-file-to-byte-array)
+* [upload file](#upload-file-from-byte-array)
+* [get information about specified file/folder](#get-information-about-specified-filefolder)
+* [move file to another location](#move-file-to-another-location)
+* [copy file to another location](#copy-file-to-another-location)
+* [delete file](#delete-file)
+
+## Usage
+
+First of all you should create `Client` instance using `NewClient()` function:
+
+```go
+root := "https://webdav.mydomain.me"
+user := "user"
+password := "password"
+
+c := gowebdav.NewClient(root, user, password)
+```
+
+After you can use this `Client` to perform actions, described below.
+
+**NOTICE:** we will not check errors in examples, to focus you on the `gowebdav` library's code, but you should do it in your code!
+
+### Create path on a WebDAV server
+```go
+err := c.Mkdir("folder", 0644)
+```
+In case you want to create several folders you can use `c.MkdirAll()`:
+```go
+err := c.MkdirAll("folder/subfolder/subfolder2", 0644)
+```
+
+### Get files list
+```go
+files, _ := c.ReadDir("folder/subfolder")
+for _, file := range files {
+ //notice that [file] has os.FileInfo type
+ fmt.Println(file.Name())
+}
+```
+
+### Download file to byte array
+```go
+webdavFilePath := "folder/subfolder/file.txt"
+localFilePath := "/tmp/webdav/file.txt"
+
+bytes, _ := c.Read(webdavFilePath)
+ioutil.WriteFile(localFilePath, bytes, 0644)
+```
+
+### Download file via reader
+Also you can use `c.ReadStream()` method:
+```go
+webdavFilePath := "folder/subfolder/file.txt"
+localFilePath := "/tmp/webdav/file.txt"
+
+reader, _ := c.ReadStream(webdavFilePath)
+
+file, _ := os.Create(localFilePath)
+defer file.Close()
+
+io.Copy(file, reader)
+```
+
+### Upload file from byte array
+```go
+webdavFilePath := "folder/subfolder/file.txt"
+localFilePath := "/tmp/webdav/file.txt"
+
+bytes, _ := ioutil.ReadFile(localFilePath)
+
+c.Write(webdavFilePath, bytes, 0644)
+```
+
+### Upload file via writer
+```go
+webdavFilePath := "folder/subfolder/file.txt"
+localFilePath := "/tmp/webdav/file.txt"
+
+file, _ := os.Open(localFilePath)
+defer file.Close()
+
+c.WriteStream(webdavFilePath, file, 0644)
+```
+
+### Get information about specified file/folder
+```go
+webdavFilePath := "folder/subfolder/file.txt"
+
+info := c.Stat(webdavFilePath)
+//notice that [info] has os.FileInfo type
+fmt.Println(info)
+```
+
+### Move file to another location
+```go
+oldPath := "folder/subfolder/file.txt"
+newPath := "folder/subfolder/moved.txt"
+isOverwrite := true
+
+c.Rename(oldPath, newPath, isOverwrite)
+```
+
+### Copy file to another location
+```go
+oldPath := "folder/subfolder/file.txt"
+newPath := "folder/subfolder/file-copy.txt"
+isOverwrite := true
+
+c.Copy(oldPath, newPath, isOverwrite)
+```
+
+### Delete file
+```go
+webdavFilePath := "folder/subfolder/file.txt"
+
+c.Remove(webdavFilePath)
+```

+# Description
+Command line tool for [gowebdav](https://github.com/studio-b12/gowebdav) library.
+
+# Prerequisites
+## Software
+* **OS**: all, which are supported by `Golang`
+* **Golang**: version 1.x
+* **Git**: version 2.14.2 at higher (required to install via `go get`)
+
+# Install
+```sh
+go get -u github.com/studio-b12/gowebdav/cmd/gowebdav
+```
+
+# Usage
+It is recommended to set following environment variables to improve your experience with this tool:
+* `ROOT` is an URL of target WebDAV server (e.g. `https://webdav.mydomain.me/user_root_folder`)
+* `USER` is a login to connect to specified server (e.g. `user`)
+* `PASSWORD` is a password to connect to specified server (e.g. `p@s$w0rD`)
+
+In following examples we suppose that:
+* environment variable `ROOT` is set to `https://webdav.mydomain.me/ufolder`
+* environment variable `USER` is set to `user`
+* environment variable `PASSWORD` is set `p@s$w0rD`
+* folder `/ufolder/temp` exists on the server
+* file `/ufolder/temp/file.txt` exists on the server
+* file `/ufolder/temp/document.rtf` exists on the server
+* file `/tmp/webdav/to_upload.txt` exists on the local machine
+* folder `/tmp/webdav/` is used to download files from the server
+
+## Examples
+
+#### Get content of specified folder
+```sh
+gowebdav -X LS temp
+```
+
+#### Get info about file/folder
+```sh
+gowebdav -X STAT temp
+gowebdav -X STAT temp/file.txt
+```
+
+#### Create folder on the remote server
+```sh
+gowebdav -X MKDIR temp2
+gowebdav -X MKDIRALL all/folders/which-you-want/to_create
+```
+
+#### Download file
+```sh
+gowebdav -X GET temp/document.rtf /tmp/webdav/document.rtf
+```
+
+You may do not specify target local path, in this case file will be downloaded to the current folder with the
+
+#### Upload file
+```sh
+gowebdav -X PUT temp/uploaded.txt /tmp/webdav/to_upload.txt
+```
+
+#### Move file on the remote server
+```sh
+gowebdav -X MV temp/file.txt temp/moved_file.txt
+```
+
+#### Copy file to another location
+```sh
+gowebdav -X MV temp/file.txt temp/file-copy.txt
+```
+
+#### Delete file from the remote server
+```sh
+gowebdav -X DEL temp/file.txt
+```
+
+# Wrapper script
+
+You can create wrapper script for your server (via `$EDITOR ./dav && chmod a+x ./dav`) and add following content to it:
+```sh
+#!/bin/sh
+
+ROOT="https://my.dav.server/" \
+USER="foo" \
+PASSWORD="$(pass dav/foo@my.dav.server)" \
+gowebdav $@
+```
+
+It allows you to use [pass](https://www.passwordstore.org/ "the standard unix password manager") or similar tools to retrieve the password.
+
+## Examples
+
+Using the `dav` wrapper:
+
+```sh
+$ ./dav -X LS /
+
+$ echo hi dav! > hello && ./dav -X PUT /hello
+$ ./dav -X STAT /hello
+$ ./dav -X PUT /hello_dav hello
+$ ./dav -X GET /hello_dav
+$ ./dav -X GET /hello_dav hello.txt
+```
