Markdown to Telegram MarkdownV2 Converter

Description

Telegram Bot API has several options to format sending messages with a parameter parse_mode. One of them is MarkdownV2.

It has similar syntax to normal markdown, however it can be a problem to convert already existent Markdown text to Telegram MarkdownV2.

Features

1. Convert Markdown Bold (**Bold**) to Telegram MarkdownV2 Bold (*Bold*)
2. Convert Markdown Italic (*Italic* or _Italic_) to Telegram MarkdownV2 Italic (_Italic_)
3. Convert Markdown Strikethrough (~Strikethrough~) to Telegram MarkdownV2 Italic (~Strikethrough~)
4. Parse unwrapped links (https://example.com) and wrap them ([https://example.com](https://example.com))
5. Parse Markdown inline code and code blocks and escape special chars inside them for Telegram MarkdownV2.

Usage

package main 

import (
    "github.com/zavitkov/tg-markdown"
    "fmt"
)

func main() {
    markdown := `This is **bold** *italic* ~strikethrough~ text with [wrapped](https://github.com/zavitkov/tg-markdown) link and unwrapped link: https://github.com/zavitkov/tg-markdown`

    tgMarkdownV2 := tg_markdown.ConvertMarkdownToTelegramMarkdownV2(markdown)
    fmt.Println(tgMarkdownV2)
	
    //output: This is *bold* _italic_ ~strikethrough~ text with [wrapped](https://github.com/zavitkov/tg-markdown) link and unwrapped link: [https://github\.com/zavitkov/tg\-markdown](https://github.com/zavitkov/tg-markdown)
