Feature Request: Themes/color control

[rien333]

Any way to change the color output? By default, my html comments are green, which for longer comments makes them quite hard to read in my theme (which might be partly due to my theme being at fault; nonetheless, being able to change it from green could improve readability under some circumstances)

Themes would be a more general solution, but an option that allows for more fine-grained control of colors could also be handy.

As a slight bonus, it would be neat if themeing would allow you to se text properties (e.g. disabling bold headers, making comments italic but the same color as regular text, etc).

There’s no such feature, and I for my part won’t add it myself; I just don’t need it.

I’m open for pull requests though.

I think I’ll make mdcat use syntect themes for colouring and styling and add means to change the theme via env vars, like bat does it. This would also simplify code a bit.

Would this work for you?

[rien333]

Sure it would!

[swsnr]

Great.

Note to self: Use appropriate markdown scopes for elements in rendered output; see Markdown syntax definition for a list of possible scopes.

We’ll also at some point want to check COLORTERM for 24bit support and use ansi_colours to convert to 256 bit colours if the terminal doesn’t support true colours.

Or we’ll just dump 24bit escape codes and hope that the terminal emulator copes, in whatever way 🤷‍♂️

Closing this, because I don't intend to do anything about this any time soon. Some basic infrastructure exists, but as things stand I'm happy with the default colours, and won't change anything here.

Pull requests are welcome.

I would also majorly support this feature (but can't contribute code as I don't know rust - yet! 😅 ). With 2k stars to date I'm honestly suprised this hasn't been requested more often.

For example, I use iTerm2 with a pretty standard dark mode theme, and TOC links are nearly unreadable in all but the darkest rooms:

If not a full suite of different themes like bat, perhaps it would be more tractable to implement just two, one optimized for light more and one for dark mode?

This one niggle aside, major love for mdcat! Definitely the best command line Markdown viewer around.

Hi, I am very confused. The README shows different themes:

mdcat in WezTerm, with "One Light (base16)", "Gruvbox Light", and "Darcula (base16)" (from left to right)

and it says you can use syntect code highlighting:

highlights code blocks with syntect,

How do i select the general theme, and/or the code highlighting theme? In bat I use:

export BAT_THEME="Visual Studio Dark+"

Do I have to select it in the source code and compile myself? Thanks.

[swsnr]

You can't. The screenshot shows different themes of the terminal emulator, IE, you'd select these in reg Wezterm config.

mdcat does not support custom themes.

@swsnr Thanks for the quick feedback. How about syntect code highlighting? I am also having a look at t https://github.com/Inlyne-Project/inlyne.

[swsnr]

mdcat uses a fixed set of colors for syntect highlighting. There is no custom theme support in mdcat. Really. 😉
