Formatting#

Make your message formatting flexible and simple

This instrument works on top of Message entities instead of using HTML or Markdown markups, you can easily construct your message and sent it to the Telegram without the need to remember tag parity (opening and closing) or escaping user input.

Usage#

Basic scenario#

Construct your message and send it to the Telegram.

content = Text("Hello, ", Bold(message.from_user.full_name), "!")
await message.answer(**content.as_kwargs())

Is the same as the next example, but without usage markup

await message.answer(
    text=f"Hello, <b>{html.quote(message.from_user.full_name)}!",
    parse_mode=ParseMode.HTML
)

Literally when you execute as_kwargs method the Text object is converted into text Hello, Alex! with entities list [MessageEntity(type='bold', offset=7, length=4)] and passed into dict which can be used as **kwargs in API call.

The complete list of elements is listed on this page below.

Advanced scenario#

On top of base elements can be implemented content rendering structures, so, out of the box aiogram has a few already implemented functions that helps you to format your messages:

and lets complete them all:

content = as_list(
    as_marked_section(
        Bold("Success:"),
        "Test 1",
        "Test 3",
        "Test 4",
        marker="✅ ",
    ),
    as_marked_section(
        Bold("Failed:"),
        "Test 2",
        marker="❌ ",
    ),
    as_marked_section(
        Bold("Summary:"),
        as_key_value("Total", 4),
        as_key_value("Success", 3),
        as_key_value("Failed", 1),
        marker="  ",
    ),
    HashTag("#test"),
    sep="\n\n",
)

Will be rendered into:

Success:

✅ Test 1

✅ Test 3

✅ Test 4

Failed:

❌ Test 2

Summary:

Total: 4

Success: 3

Failed: 1

#test

Or as HTML:

<b>Success:</b>
✅ Test 1
✅ Test 3
✅ Test 4

<b>Failed:</b>
❌ Test 2

<b>Summary:</b>
  <b>Total:</b> 4
  <b>Success:</b> 3
