Multiple moulti in parallel

[huyz]

For my Ansible scripts, I actually run playbooks in parallel in separate terminal tabs (because my machines are more like pets than cattle).

But I get the following error:

Fatal: cannot listen on /Users/huyz/Library/Caches/moulti/moulti-huyz-default.socket (with backlog=100 and blocking=False): [Errno 48] Address already in use

Is there a simple way to run multiple moultis at the same time without conflict?

Each Moulti instance has a name, and that name defaults to default.
To run multiple Moulti instances concurrently, they need to have different names.
Typically: MOULTI_INSTANCE=ansible-$$ moulti run -- ansible-playbook ...

Update: as of Moulti 1.30.0, this is no longer required.
Excerpt from the changelog for v1.30.0:

• moulti run now suffixes the instance name with its process id (e.g. default-1234 instead of default).
  This helps prevent clashes and makes it possible to run various tools concurrently without having to worry about such details.
  This behaviour can be prevented by setting the MOULTI_RUN_NO_SUFFIX environment variable or using the -n / --no-suffix command-line option.
  The behaviour of moulti init remains unchanged.
• moulti run, moulti diff run, moulti manpage run: it is no longer mandatory to use -- to separate Moulti arguments and the > command to be run.

Otherly put: moulti run ansible-playbook ... should work out of the box: no need to specify MOULTI_INSTANCE, no need to use --.
