Escape codes visible in code block

I do not see escape codes when running pygmentize directly:

I'll have to look into this, can't guarantee I'll get to it right away.

I have the same issue in the Windows console (what I get when I run bash.exe):  Is it me? Or is it something in mdless? Here is my source file (just take out the backslashes), to reproduce: ``` The promise type is always followed by a single colon. \```cfengine3 files: "/etc/nologin" create => "true", comment => "Prevent non-root users from logging in"; \``` ``` If I run mdless with --no-color, the escape codes disappear -- but I want the color. :) -- You are receiving this because you are subscribed to this thread.

Got it, and thank you very much for the acknowledgement, Brett! :) Best, Aleksey On Fri, Jan 15, 2021 at 4:17 AM Brett Terpstra <[email protected]> wrote:

Here is another data point. I moved to another system (moved my development from an AWS EC2 instance to a Vagrant VM). Also moved from RHEL 8.3 to CentOS 7. What I'm seeing now is extra blank lines inserted after the line with files: in it. Also the bottom line (horizontal line) is broken:

Oops, I just realized I didn't install pygments. So I've installed python-pygments (python2) and now I get:

Well, that older pygmentize doesn't know about my language:

[root@localhost source]# pygmentize -L|grep cf3
[root@localhost source]#

[atsaloli]

Okay, I've reproduced the issue (escape codes visible in code block) using the latest pygmentize:

One more data point: If I add a header to my markdown source, the escape codes in the code block disappear.

Here is my markdown source:

[sebastianoc]

I don't know if it is the case for you, but I worked out that I was seeing the Escape codes because my PAGER was most

export PAGER=most
 echo '#h1
' | mdless 

^[[0;1;47;90mh1 ===

The workaround is to disable the PAGER with the -P switch or change your PAGER to less or something else.

Workaround

export PAGER=less

or

echo '#h1
' | PAGER=less mdless

Thanks, sebastiano. My pager is "less". :) Best, Aleksey

Sorry it took me so long to get back around to this, @atsaloli . Did you ever find a resolution for the issue?

[atsaloli]

I found a workaround @ttscoff -- see atsaloli/cf3-tutorial@fee89be

As noted in #60 (comment) my workaround is to add a header

Thanks for following up! :)

I was very happy to be able to teach my class using mdless
