Is it possible to format the text? #11

Closed aeri closed 3 years ago

aeri commented 3 years ago

I would like to be able to apply styles as specified in the Telegram style guide (https://core.telegram.org/bots/api#html-style) but I can't get.

I saw something mentioned about it in #8 but I'm not sure if any progress was made on it.

When i log something like:

Serilog.Log.Write(LogEventLevel.Warning, $"<b>bold</b>");

I receive in my chat: &lt;b&gt;bold&lt;/b&gt;

Is it possible to apply formatting in any way with this library?

Thank you.

I can provide a switch that allows to format the messages as you like (something like a bool allowHtmlFormatting = true. In general, the special HTML chars are HTML encoded (as you already figured out) to avoid formatting issues in Telegram.

That would be great, as far as I see HTML is not currently supported, but is it possible to use now other format techniques like Markdown?

I had some serious trouble with Markdown and MarkdownV2 formatting (To make it look good in Telegram). Please don't ask me what exactly was the problem because I don't really remember. I only know that it was really complicated to construct and escape the characters.

So, if you ask me, the boolean flag (Like a 'I know what I'm doing' flag) is the best option for that and doesn't affect the other users if the default is set to false.

With the next version, you can now use the option useCustomHtmlFormatting and set it to true. I have added a test where this is shown --> Check out: https://github.com/serilog-contrib/Serilog.Sinks.Telegram.Alternative/blob/761e2185a7381c1c2ad29de99e06acb8d91110e5/src/Serilog.Sinks.Telegram.Tests/TestSink.cs#L455
