K-9: Feature Request: Send HTML formated mails

[moshpirit]

Expected behavior

It would be cool to send mails with bold, _italics_, _underlined_ and crossed words, lists, etc. Maybe using MarkDown or a button that showed a "formating bar" (maybe at the bottom of the screen?).

Note: a preview button or a live preview would be also very appreciated.

Actual behavior

There's no way to do it

Environment

K-9 Mail version: 5.114 (F-droid)

Android version: 6.0.1

Account type (IMAP, POP3, WebDAV/Exchange): IMAP

The hard part is developing a UI that is usable given the Android screen size and number of possible options.

I think the best library for this is probably https://github.com/1gravity/Android-RTEditor

From the screenshots it looks like the K@-Mail fork actually uses it. RTEditor is Apache 2.0 licensed (like K-9) so it is fine for us to use as well.

I don't tend to need to write formatted email so this is quite low on my priority list. If someone wants to pick it up I'm happy to review code though.

I think that considering the UI problems using markdown or similar typable markup languages is probably the way to go.

I personally would like to see this feature, if markdown is considered an option I will probably start working on it.

Have you taken a look at Memento note taking app? https://github.com/yaa110/Memento
Just found it myself. It has limited rich text capabilities, but the UI is very intuitive. Being able to change colors and embed tables and images seems like a must have nowadays. Switching to markup would be a great feature to support advanced editing.

The toolbar could be placed on a menu or pop up window to save space, just some thoughts.

Also looked at RichEditor for Android, https://github.com/wasabeef/richeditor-android , but it has not been updated in years.

Great App guys!

Memento seems to use RichEditor, and that lib has actually been updated roughly a year ago. Looks nice though, we should take it into consideration

Is there any way this could be prioritised? K9 is the best email app for Android but whenever I recommend it I always have to say 'but you can't format your emails at all'. Then they look at me like I've travelled from the ancient past (which I sort of have I guess!).
The other popular email apps I've had a look at all allow formatting: they may be inferior to K9 in a thousand ways, but formatting does seem to be regarded as a basic function now.
Afraid I can't code but very happy to test.

Same here this quite and old request and any modern app out there supports
rich text by default so I can't understand why k-9 does not.

any chance that any rich text support will be implemented soon?

[cketti]

Incomplete list of things that implementations have to take into account:

• The 'message format' setting needs to be respected. Don't enable rich text editing when composing plain text messages.
• There should be a quick way to show/hide the formatting toolbar; this state should persist. I imagine most people only occasionally use formatting features. So having the toolbar hidden most of the time and being able to bring it up quickly seems like a valuable feature.
• When editing drafts in "rich text mode" load the text/html part of the draft. Check the contents and display a warning if the draft contains HTML tags that the editor doesn't support.
• Currently, when composing a message, we create the text/html part from the plain text the user has entered. With a rich text editor we'll have to create the text/plain part from HTML. For this to work well in practice we'll probably have to dramatically enhance the capabilities of HtmlToPlainText.
• Add support for EXTRA_HTML_TEXT.

This feature requires a lot of changes and chances are we will introduce quite a few bugs in the process. Because of this I want us to have a build flag to be able to disable this feature for stable versions until the feature is stable enough.

There is lib which could suit for typeface toolbar and edittext: https://github.com/wordpress-mobile/AztecEditor-Android/
It is design to write html code but we could use only the text editor part.

I understand the work needed to add an html editor and so to send actual html email.
Since in settings we can choose to send html emails, would be an option to set content-type to text/html when those settings is specified? It would allow to add and correctly read an html signature at least.
