[bedge]

Describe the bug
From CMD:

C:\Users\edgeb1>copyq --help
<no output>

From powershell

➜ copyq --help
<no output>

From Gitbash

edgeb1@RSCMW3512 MINGW64 ~
$ copyq --help
<no output>

To Reproduce

1. Run copyq --help from any available shell.

Expected behavior
Should display help options

Version, OS and Environment

that said, windows 11, copyq 9.1.0

• Application Version (for example 7.1.0)
  9.1.0

• OS (for example Windows 11, Ubuntu 22.04, macOS Sonoma 14.4)
  windows 11

• Desktop environment, window manager (if applicable)
  windows 11

Additional context
I am able to run copyq --add XXX to add things to the clipboard.
I just get no output from any copyq shell commands

I found this:
#2852 (comment)
stating:

Unfortunately, this is a known problem on Windows (I don't see a way to fix this).

See: https://copyq.readthedocs.io/en/latest/known-issues.html#on-windows-copyq-does-not-print-anything-on-console

But the documentation link is sorely lacking.

How is this supposed to fix it?

This has no effect in GitBash, or CMD

[bedge]

Is this not indicative of needing to change the mechanism used to print to stdout for windows targets?
I have not looked at the code, but there's usually half a dozen abstractions one can use for stdout processing, no?

run this
.\copyq.exe --help | echo

buffer error with windows if it works.

[bedge]

Yes, that works:

C:\Program Files\CopyQ>.\copyq.exe --help | echo
ECHO is on.
