HTML Formatting

Add bold, italic, links, headings, and code blocks to your messages.

Supported tags

Tag	Effect
`<b>text</b>`	Bold
`<i>text</i>`	Italic
`<u>text</u>`	Underline
`<s>text</s>`	~~Strikethrough~~
`<code>text</code>`	`Monospace` (inline)
`<pre>text</pre>`	Preformatted block
`<h1>text</h1>`	Heading
`<a href="url">text</a>`	Clickable link

How to use it

Pass parse_mode="html" to any method that sends text:

await bot.send_message(
    chat_id,
    "<b>bold</b> <i>italic</i> <a href='https://ok.ru'>link</a>",
    parse_mode="html"
)

HTML works in replies and captions too:

await bot.send_reply(message, "<b>bold reply</b>", parse_mode="html")
await bot.send_photo(chat_id, url, caption="<i>caption</i>", parse_mode="html")

Full example

@bot.on_message(commands=["html"])
async def cmd_html(message):
    text = """
<b>Bold</b>
<i>Italic</i>
<u>Underline</u>
<s>Strikethrough</s>
<code>inline code</code>
<pre>preformatted
block</pre>
<h1>Heading</h1>
<a href="https://ok.ru">OK.ru</a>
    """
    await bot.send_reply(message, text.strip(), parse_mode="html")

See examples/html_demo_bot.py for a live demo.

Under the hood

pyokbot uses sulguk to convert your HTML into OK.ru's entity format.  becomes STRONG,  becomes EMPHASIZED, <a> becomes LINK, and so on.

Notes

Tags must be properly closed. Unclosed tags get ignored.
parse_mode defaults to None (plain text). You have to set it to "html" explicitly.
You can nest tags: bold italic works fine.
