Conan: output is not saved when using self.run() with win_bash=True

[zlalanne]

To help us debug your issue please explain:

Using Conan version 1.18.1 on Windows. Running conan from the git bash shell that comes with the Windows git installation.

I'm packaging up some tools to use in our Conan infrastructure. As part of our test_package I like to run the tool to just verify the tool was added to the PATH correctly and can be run. One test I do is run a tool with --version to check that the version packaged was the one intended.

What I'm having trouble with is conan doesn't seem to capture STDOUT when callign tools using self.run() when win_bash=True).

So something like this doesn't actually work:

buffer = StringIO()
self.run("ls --version", output=buffer, win_bash=True)

# This does not print anything. STDOUT was not captured.
print("My output was:")
print(buffer.getvalue())

• [x] I've read the CONTRIBUTING guide.
• [x] I've specified the Conan version, operating system version and any tool that can be relevant.
• [x] I've explained the steps to reproduce the error or the motivation/use case of the question/suggestion.

You are right, it is actually written in the sources as a FIXME 😓

I haven't used slack, how to use it?

Slack is an application like the old IRC, there is one C++ community with people all over the world (http://cpplang.slack.com) with many channels to talk about different C++ topics. There is one channel dedicated to #conan where you can share your experience, ask for help,... See you there! ;D
