Can't open Dockerfile or .dockerfile

[davidfilat]

I have installed the latest build and tried to open the Dockerfile for my project and it didn't open at all. I mean nothing happened, the prompt just asked me for the next command.

Thank you for reporting this.

Could you please show the output of

ls -l Dockerfile
file Dockerfile
cat Dockerfile

[davidfilat]

Of course. Here they are:

I would guess that something is wrong with your pager. Could you try to run

bat --paging=never Dockerfile

?

To debug this further, could you please show the output of the following script:

set -x

bat --version
bat --config-file
bat --cache-dir
less --version

bat "$(bat --config-file)"
ls "$(bat --cache-dir)"

set +x

echo "BAT_PAGER = '$BAT_PAGER'"
echo "BAT_CONFIG_PATH = '$BAT_CONFIG_PATH'"
echo "BAT_STYLE = '$BAT_STYLE'"
echo "BAT_THEME = '$BAT_THEME'"
echo "BAT_TABS = '$BAT_TABS'"
echo "PAGER = '$PAGER'"
echo "LESS = '$LESS'"

The bat --paging=never Dockerfile command worked and it displayed the text correctly.
I have attached the debugging information you requested below and I hope it will help you fix this issue! Thank you very much, @sharkdp !

@sharkdp I wanted to let you know that installing the Homebrew version of less pager fixed the issue for me. It seems the Less version delivered with Catalina is outdated.
Maybe you could add less as a dependency for the Homebrew formulae and for add to the FAQs the suggestion to update less, for those who struggle with the same problem.
Thank you very much for your help!

[sharkdp]

The problem is that you added --pager="less -FR" to your bat configuration file. If you remove that line, it would also work with older versions of less (see the comment above that line).

Still, adding less as a dependency for bat might be a good idea for a better UX, but that has to be decided upstream in the Homebrew repository. I'm not personally maintaining the Homebrew package and don't use macOS myself.

Than you very much for your help, @sharkdp! Deeply appreciate it!
