Originally created by @VladimirAlexiev on GitHub (Nov 4, 2019).

Environment

Microsoft Windows Version 10.0.18362.418, whose cmd includes the new Terminal tab/options (eg see https://devblogs.microsoft.com/commandline/new-experimental-console-features/)

Any other software?

Steps to reproduce

wdq help

Expected behavior

Should show modestly colored output:

Actual behavior

Shows escape sequences:

wdq [ MODE ] [ OPTIONS ] [ REQUEST | < REQUEST_FILE ]
Usage:
  Access Wikidata Query Service <https://query.wikidata.org/> via command                                      
  line to perform SPARQL queries ("query" mode), lookup entities ("lookup"),
  or search items and properties ("search" or "psearch"):                                                                                                                                                                     ...
  See the manual for details or get help via "wdq help":

Through file

If I save the output to a file (-C explicitly enables color mode) then type or cat the file to the microsoft terminal, the color shows ok:

wdq -C help > wdq-help.txt 
type wdq-help.txt 
cat wdq-help.txt

The saved file: wdq-help.txt

So I thought the problem may be related to some startup magic? The file starts like this:

>head /cygdrive/c/Strawberry/perl/site/bin/wdq
#!/usr/bin/env perl
use v5.14;

Starting perl explicitly makes no difference:

perl -S wdq help

@zadjii-msft commented on GitHub (Nov 4, 2019):

So admittedly, I don't know a ton about how exactly clink/cygwin works. What I can say is that in order for escape sequences to work in the Windows Console (conhost.exe, the vintage terminal on Windows), applications need to explicitly call SetConsoleMode with ENABLE_VIRTUAL_TERMINAL_PROCESSING. So perhaps something in the stack here isn't calling that? @VladimirAlexiev Are there any other apps in your setup that should be displaying colors but aren't?

For the record, installing wdq in WSL does correctly display the colors:

This is because WSL itself is setting the console into the correct mode for all child processes it launches.

@zadjii-msft thanks for looking into that! What is WSL and how do I install wdq into it?

WSL is the Windows Subsystem for Linux.

You can find instructions on how to install it here.

Once you have your distro of choice, you can install wdq however you normally would on linux. IIRC this was the script I used:

wget https://github.com/nichtich/wdq/raw/master/script/wdq
chmod +x wdq
