Step 1: Provide a summary of your problem

Keep getting RuntimeError("Unable to determine handler") if parent folder contain . (dot)
If rename folder and remove dot the problem disappearing.

Step 2: Provide tmuxp details

• Python 3.8.3
• tmux 3.1b
• tmuxp 1.5.6
• zsh

Step 3: Describe your environment

• Architecture: Darwin
• OS version: 10.15.7 (19H2)

Step 4: Describe the problem:

Looks like folder shouldn't contain dot.

Steps to reproduce:

1. mkdir folderwith.dot
2. cd folderwith.dot && copy ../.tmuxp.yaml .
3. tmuxp load .

Observed Results:

  File "/usr/local/Caskroom/miniconda/base/lib/python3.8/site-packages/tmuxp/cli.py", line 834, in command_load
    load_workspace(config[-1], **tmux_options)
  File "/usr/local/Caskroom/miniconda/base/lib/python3.8/site-packages/tmuxp/cli.py", line 501, in load_workspace
    sconfig = sconfig.import_config(config_file).get()
  File "/usr/local/Caskroom/miniconda/base/lib/python3.8/site-packages/kaptan/__init__.py", line 87, in import_config
    raise RuntimeError("Unable to determine handler")

Expected Results:

Load tmuxp configuration stored in .tmuxp.yaml
