Tdesktop: Math formulas support

[ohhmm]

Steps to reproduce

1. copy formula from https://ru.wikipedia.org/wiki/%D0%A2%D0%B5%D0%BE%D1%80%D0%B5%D0%BC%D0%B0_%D0%9A%D1%80%D0%BE%D0%BD%D0%B5%D0%BA%D0%B5%D1%80%D0%B0_%E2%80%94_%D0%9A%D0%B0%D0%BF%D0%B5%D0%BB%D0%BB%D0%B8

Система уравнений
A x = b {\displaystyle Ax=b}
разрешима тогда и только тогда, когда
rank ⁡ A = rank ⁡ ( A , b ) {\displaystyle \operatorname {rank} A=\operatorname {rank} (A,b)}
, где
( A , b ) {\displaystyle (A,b)}
— расширенная матрица, полученная из матрицы
A {\displaystyle A}
приписыванием столбца
b {\displaystyle b}

Expected behaviour

Expected to use same JS framework as stackexchange or Wikipedia uses to preserve formulas.

Actual behaviour

for stackexchange it almost works

@ohhmm I can't use js frameworks :(

So you want Wikitext/LaTeX parsing in TDesktop?

To copy formulas from wikipedia and math.stackexchange.com websites.
I thought Telegram use QML in which case I imagined JS and MathML.
Wolfram bot allows formula editing. Can it be useful?

@ohhmm Telegram doesn't use QML 😔

Or just use bot platform :)
https://t.me/LatexBot can be helpful too.

Why do you need this feature? I don't think it's useful for most people. So it'll be a bloat if added to core. Bots are the way to do it.

[ohhmm]

why do I need to copy a text with image from web? it bloats source code!
lets show images through bots with pseudo graphics! Bots are the way to do
such staff.

You see, I was thinking about downloading the image to attach it here to see if it show it then but it was too hard to do. And then "Hay, I can type this text here!"

RetroShare use QML anyway. Maybe someGSOC someone will implement it in single day in RetroShare. Thank you guys, sorry for bothering.
