Syntax Highlighter Bot

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

Overview

This bot was written on top of the Telegraf.js bot framework, so all you need to have is the Node.js > v6.

Usage

Demo (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)
)\`\`\`
