# Syntax Highlighter Bot

![Travis (.org)](https://img.shields.io/travis/com/Piterden/syntax-highlighter-bot.svg?style=for-the-badge) ![GitHub search hit counter](https://img.shields.io/github/search/Piterden/syntax-highlighter-bot/highlight.svg?style=for-the-badge) ![GitHub code size in bytes](https://img.shields.io/github/languages/code-size/Piterden/syntax-highlighter-bot.svg?style=for-the-badge)

The bot for creating an image with highlighted code from a message.

## Overview

This bot was written on top of the [Telegraf.js](https://github.com/telegraf/telegraf) bot framework, so all you need to have is the Node.js > v6.

## Usage

[Demo](https://t.me/cris_highlight_bot) (WIP version).

The bot listens for entities type of `pre` in any text message. It means, it will render all pieces of text, wrapped in triple backticks (multiline code). Also you could force the language, writing its name on the first line, right after backticks. Just like on the GitHub.

Look at the example of a code should be handled by the bot:

```
\`\`\`js
/**
 * Show themes list
 */
bot.command('theme', (ctx) => isPrivateChat(ctx)
  ? ctx.replyWithMarkdown(
    messages.themeChoose(ctx.state.user.theme),
    Markup.keyboard(themesKeyboard(themes)).oneTime().resize().extra()
  )
  : ctx.reply(messages.themeGroup)
)\`\`\`
```

### Commands

- `/start` - Initial launch of the bot.
- `/theme` - Shows the list of included themes and allows you to select a theme which you like more.
- `/langs` - Shows the list of supported languages.
