glow stopped displaying colors properly with a pager

[borjator]

System

• xuname:
  Void 5.15.9_1 x86_64 GenuineIntel uptodate rFFFFF
• package:
  glow-1.4.1_1

Expected behavior

glow -p displays formatted Markdown with colors in my pager (less)

Actual behavior

It shows a lot of color codes without interpreting them:
ESC[38;5;228;48;5;63;1mESC[0mESC[38;5;228;48;5;63;1mESC[0m ESC[38;5;228;48;5;63;1m ESC[0mESC[38;5;228;48;5;63;1mHelloESC[0mESC[38;5;228;48;5;63;1m ESC[0mESC[38;5;252mESC[38;5;252m

Steps to reproduce the behavior

1. Create a simple Markdown file: echo "# Hello" > hello.md
2. Display it with glow with a pager: glow -p hello.md

I'm not completely sure if this is a glow bug since I've tried a bunch of different things:

• The previous version of glow
• Older versions of less (my favourite pager)
• I can confirm the same happens with most my second favourite pager
• I've tried to use a different terminal (xterm instead of xst)
• I tested using a different TERM environment variable just in case

Anything else I could try?

less by default does not interpret escape sequences. Try setting the LESS='-R' environment variable:
LESS='-R' glow -p index.md
It works fine too if you don't pass -p.

Thank you! That fixed the issue for me.

It's weird because I had an alias for less alias less="less -R" and that was working previously.
