The package utfbom implements the detection of the BOM (Unicode Byte Order Mark) and removing as necessary. It can also return the encoding detected by the BOM.
## Installation
go get -u github.com/dimchansky/utfbom
## Example
```go
package main
import (
"bytes"
"fmt"
"io/ioutil"
"github.com/dimchansky/utfbom"
)
func main() {
trySkip([]byte("\xEF\xBB\xBFhello"))
trySkip([]byte("hello"))
}
func trySkip(byteData []byte) {
fmt.Println("Input:", byteData)
// just skip BOM
output, err := ioutil.ReadAll(utfbom.SkipOnly(bytes.NewReader(byteData)))
if err != nil {
fmt.Println(err)
return
}
fmt.Println("ReadAll with BOM skipping", output)
// skip BOM and detect encoding
sr, enc := utfbom.Skip(bytes.NewReader(byteData))
var encStr string
switch enc {
case utfbom.UTF8:
encStr = "UTF8"
case utfbom.UTF16BigEndian:
encStr = "UTF16 big endian"
case utfbom.UTF16LittleEndian:
encStr = "UTF16 little endian"
case utfbom.UTF32BigEndian:
encStr = "UTF32 big endian"
case utfbom.UTF32LittleEndian:
encStr = "UTF32 little endian"
default:
encStr = "Unknown, no byte-order mark found"
}
fmt.Println("Detected encoding:", encStr)
output, err = ioutil.ReadAll(sr)
if err != nil {
fmt.Println(err)
return
}
fmt.Println("ReadAll with BOM detection and skipping", output)
fmt.Println()
}
```
Output:
```
$ go run main.go
Input: [239 187 191 104 101 108 108 111]
ReadAll with BOM skipping [104 101 108 108 111]

ReadAll with BOM detection and skipping [104 101 108 108 111]
Input: [104 101 108 108 111]

### Converts HTML into text of the markdown-flavored variety
## Introduction
Ensure your emails are readable by all!
Turns HTML into raw text, useful for sending fancy HTML emails with an equivalently nicely formatted TXT document as a fallback (e.g. for people who don't allow HTML emails or have other display issues).
html2text is a simple golang package for rendering HTML into plaintext.
There are still lots of improvements to be had, but FWIW this has worked fine for my [basic] HTML-2-text needs.
It requires go 1.x or newer ;)
## Download the package
```bash
go get github.com/jaytaylor/html2text
```
## Example usage
```go
package main
import (
"fmt"
"github.com/jaytaylor/html2text"
)
func main() {
inputHTML := `
<html>
<head>
<title>My Mega Service</title>
<link rel=\"stylesheet\" href=\"main.css\">
<style type=\"text/css\">body { color: #fff; }</style>
</head>
<body>

# html2text
[![Documentation](https://godoc.org/github.com/cpanato/html2text?status.svg)](https://godoc.org/github.com/cpanato/html2text)
[![Build Status](https://travis-ci.org/cpanato/html2text.svg?branch=master)](https://travis-ci.org/cpanato/html2text)
[![Report Card](https://goreportcard.com/badge/github.com/jaytaylor/html2text)](https://goreportcard.com/report/github.com/cpanato/html2text)
### Initial information
This project was forked from [github.com/jaytaylor/html2text](https://github.com/jaytaylor/html2text) in order to use another clean bom library due the original one has no license.
### Converts HTML into text
## Introduction
Ensure your emails are readable by all!
Turns HTML into raw text, useful for sending fancy HTML emails with a equivalently nicely formatted TXT document as a fallback (e.g. for people who don't allow HTML emails or have other display issues).
html2text is a simple golang package for rendering HTML into plaintext.
There are still lots of improvements to be had, but FWIW this has worked fine for my [basic] HTML-2-text needs.
It requires go 1.x or newer ;)
## Download the package
```bash
go get github.com/cpanato/html2text
```
## Example usage
```go
package main
import (
"fmt"
"github.com/cpanato/html2text"
)
func main() {
inputHtml := `
<html>
<head>
<title>My Mega Service</title>
<link rel=\"stylesheet\" href=\"main.css\">
<style type=\"text/css\">body { color: #fff; }</style>
</head>
<body>
<div class="logo">
<a href="http://mymegaservice.com/"><img src="/logo-image.jpg" alt="Mega Service"/></a>
</div>
<h1>Welcome to your new account on my service!</h1>
<p>
Here is some more information:
<ul>
<li>Link 1: <a href="https://example.com">Example.com</a></li>
<li>Link 2: <a href="https://example2.com">Example2.com</a></li>
<li>Something else</li>
</ul>
</p>
</body>
</html>
`
text, err := html2text.FromString(inputHtml)
if err != nil {
panic(err)
}
fmt.Println(text)
}
```
Output:
```
Mega Service ( http://mymegaservice.com/ )
******************************************
Welcome to your new account on my service!
******************************************
Here is some more information:
* Link 1: Example.com ( https://example.com )
* Link 2: Example2.com ( https://example2.com )
* Something else
```

[![Godoc](https://godoc.org/github.com/olekukonko/tablewriter?status.svg)](https://godoc.org/github.com/olekukonko/tablewriter)
Generate ASCII table on the fly ... Installation is simple as
go get github.com/olekukonko/tablewriter
#### Features
- Automatic Padding
- Support Multiple Lines
- Supports Alignment
- Support Custom Separators
- Automatic Alignment of numbers & percentage
- Write directly to http , file etc via `io.Writer`
- Read directly from CSV file
- Optional row line via `SetRowLine`
- Normalise table header
- Make CSV Headers optional
- Enable or disable table border
- Set custom footer support
- Optional identical cells merging
- Set custom caption
- Optional reflowing of paragrpahs in multi-line cells.
#### Example 1 - Basic
```go
data := [][]string{
[]string{"A", "The Good", "500"},
[]string{"B", "The Very very Bad Man", "288"},
[]string{"C", "The Ugly", "120"},
[]string{"D", "The Gopher", "800"},
}
table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Name", "Sign", "Rating"})
for _, v := range data {
table.Append(v)
}
table.Render() // Send output
```
##### Output 1
```
+------+-----------------------+--------+
| NAME | SIGN | RATING |
+------+-----------------------+--------+
| A | The Good | 500 |
| B | The Very very Bad Man | 288 |
| C | The Ugly | 120 |
| D | The Gopher | 800 |
+------+-----------------------+--------+
```
#### Example 2 - Without Border / Footer / Bulk Append
```go
data := [][]string{
[]string{"1/1/2014", "Domain name", "2233", "$10.98"},
[]string{"1/1/2014", "January Hosting", "2233", "$54.95"},
[]string{"1/4/2014", "February Hosting", "2233", "$51.00"},
[]string{"1/4/2014", "February Extra Bandwidth", "2233", "$30.00"},
}
table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Date", "Description", "CV2", "Amount"})
table.SetFooter([]string{"", "", "Total", "$146.93"}) // Add Footer
table.SetBorder(false) // Set Border to false
table.AppendBulk(data) // Add Bulk Data
table.Render()
```
##### Output 2
```
DATE | DESCRIPTION | CV2 | AMOUNT
+----------+--------------------------+-------+---------+
1/1/2014 | Domain name | 2233 | $10.98
1/1/2014 | January Hosting | 2233 | $54.95
1/4/2014 | February Hosting | 2233 | $51.00
1/4/2014 | February Extra Bandwidth | 2233 | $30.00
+----------+--------------------------+-------+---------+
TOTAL | $146 93
+-------+---------+
```
#### Example 3 - CSV
```go
table, _ := tablewriter.NewCSV(os.Stdout, "testdata/test_info.csv", true)
table.SetAlignment(tablewriter.ALIGN_LEFT) // Set Alignment
table.Render()
```
##### Output 3
```
+----------+--------------+------+-----+---------+----------------+
| FIELD | TYPE | NULL | KEY | DEFAULT | EXTRA |
+----------+--------------+------+-----+---------+----------------+
| user_id | smallint(5) | NO | PRI | NULL | auto_increment |
| username | varchar(10) | NO | | NULL | |
| password | varchar(100) | NO | | NULL | |
+----------+--------------+------+-----+---------+----------------+
```
#### Example 4 - Custom Separator
```go
table, _ := tablewriter.NewCSV(os.Stdout, "testdata/test.csv", true)
table.SetRowLine(true) // Enable row line
// Change table lines
table.SetCenterSeparator("*")
table.SetColumnSeparator("‡")
table.SetRowSeparator("-")
table.SetAlignment(tablewriter.ALIGN_LEFT)
table.Render()
```
##### Output 4
```
*------------*-----------*---------*
╪ FIRST NAME ╪ LAST NAME ╪ SSN ╪
*------------*-----------*---------*
╪ John ╪ Barry ╪ 123456 ╪
*------------*-----------*---------*
╪ Kathy ╪ Smith ╪ 687987 ╪
*------------*-----------*---------*
╪ Bob ╪ McCornick ╪ 3979870 ╪
*------------*-----------*---------*
```
#### Example 5 - Markdown Format
```go
data := [][]string{
[]string{"1/1/2014", "Domain name", "2233", "$10.98"},
[]string{"1/1/2014", "January Hosting", "2233", "$54.95"},
[]string{"1/4/2014", "February Hosting", "2233", "$51.00"},
[]string{"1/4/2014", "February Extra Bandwidth", "2233", "$30.00"},
}
table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Date", "Description", "CV2", "Amount"})
table.SetBorders(tablewriter.Border{Left: true, Top: false, Right: true, Bottom: false})
table.SetCenterSeparator("|")
table.AppendBulk(data) // Add Bulk Data
table.Render()
```
##### Output 5
```
| DATE | DESCRIPTION | CV2 | AMOUNT |
|----------|--------------------------|------|--------|
| 1/1/2014 | Domain name | 2233 | $10.98 |
