Hi! Thanks for creating this software! I tried to run it in Termux app on Android but it doesn't work... See the attached screenshot.

What i did:

pkg install ruby # successful
gem install mdless # successful
mdless --help

Your OS lacks the tput command, which is what mdless uses for calculating column width of the terminal. It won't run without that.

Thank you!!! 😄 so the complete procedure to install mdless on Termux is the following:

apt update
apt install ruby ncurses-utils
gem install mdless

I suggest to add it to the README file of this repo 😉

@leder11011 FYI if it can be useful to you, as of today I'm using this solution to view markdown files with syntax highlighting in Termux:

nano -\$v README.md

Or you can also use:

vim -R README.md

Of course it's not exactly the same thing, but actually I find myself pretty comfortable with those.

If you want to view a markdown file from a URL instead:

nano -\$v <(curl -sSL https://raw.githubusercontent.com/dmotte/desktainer/main/README.md)

Of course it's just an example

thank you @dmotte !
I am even unable to open markdown file this way:

mdless test.md

what I actually need is piping the markdown output of my program:

ls -l | mdless

For both I get the error.

Do you have an idea for that, too?

@leder11011 Yep, sure. In your ls -l case, the command becomes:

nano -\$v <(ls -l)

Tested and works in Termux.

Please keep in mind that my solution is only a workaround and it's not actually using mdless. If you really want to use mdless, refer to @ttscoff 's answer for the real solution. Thanks @ttscoff for that! :)
