Question

Title is selfdescriptive.

Additional context and details

Trying

config nu --doc | nu-highlight | less -R | batpipe

Returns this:

There is no -l option ("less --help" for help)
# batpipe, a bat-based preprocessor for less and bat.
# Version: 2024.08.24
# Homepage: https://github.com/eth-p/bat-extras
# Copyright (C) 2019-2021 eth-p | MIT License
#
# To use batpipe, eval the output of this command in your shell init script.
LESSOPEN="|/opt/homebrew/Cellar/bat-extras/2024.08.24/bin/batpipe %s";
export LESSOPEN;
unset LESSCLOSE;

# The following will enable colors when using batpipe with less:
LESS="$LESS -R";
BATPIPE="color";
export LESS;
export BATPIPE;

which of course is not valid nu code.
Everything I've tried fails misserably :(

The Nushell equivalent should be:

$env.LESSOPEN = "|/opt/homebrew/Cellar/bat-extras/2024.08.24/bin/batpipe %s"
$env.LESS = "$LESS -R"
$env.BATPIPE = "color"

To get that handled dynamically, you should be able to use something like:

batpipe
| lines                 # convert to Nushell list
| where $it =~ '='      # find lines with an assignment (equals)
| parse '{var}={val};'  # turn it into a table with var and value
| transpose -dr         # turn that into a record
| load-env              # load that record into the environment
