--pretty=all piped to a pager does not work on Windows

[jkstrauss]

I am trying to use --pretty=all or --pretty=colors to color my output that I am piping to less -r. However, the colors do not show. This could also be solved by adding a paging option for long outputs (like in Git), but I understand that that is much more difficult. I am running this in Git Bash 2.21.0, and also in CMD on Windows piping to more. Neither do the coloring.

$ http --debug --pretty=all https://api.github.com | less -r

[ovezovs]

I will look into it

[ovezovs]

I was able to replicate the issue using the 'more' command on windows. I wonder if it colors the output on Unix/Linux, @jakubroztocil, when piping the output to less.

[jkbrzt]

@ovezovs yes, the following command should result in colorized output shown in less (notice the -r):

http --pretty=all httpbin.org/get | less -r

@jkstrauss which windows console did you use?

[ovezovs]

@ovezovs yes, the following command should result in colorized output shown in less (notice the -r):

http --pretty=all httpbin.org/get | less -r

@jkstrauss which windows console did you use?

I used PowerShell and VS Code terminal

[jkbrzt]

@ovezovs more also supports/requires -r:

http --pretty=all httpbin.org/get | more -r
