tmuxp freeze cause IndexError

[leechannl]

Hi, I just ran tmuxp freeze test in a tmux window, and got the following traceback:

~/workspace/tmuxp/ [master]tmuxp freeze test
Traceback (most recent call last):
  File "/home/maomao/.virtualenvs/tmuxp/bin/tmuxp", line 9, in <module>
    load_entry_point('tmuxp==0.1.0rc2', 'console_scripts', 'tmuxp')()
  File "/home/maomao/workspace/tmuxp/tmuxp/cli.py", line 958, in main
    command_freeze(args)
  File "/home/maomao/workspace/tmuxp/tmuxp/cli.py", line 336, in command_freeze

  File "/home/maomao/workspace/tmuxp/tmuxp/util.py", line 159, in findWhere
    return self.where(attrs)[0] or None
IndexError: list index out of range

The tmuxp version I installed is: 0.1.0rc4, and it's in a virtualenv.
I use zsh, and Oh-my-Zsh.
Python version is Python 2.7.5+.
My OS is Ubuntu 13.10.
Besides, I ran the tests, all pass.

@leechannl Thank you for the report!

Does this happen if the panes only use bash?

What is your PS1 in zsh / what is the oh-my-zsh theme?

What windows were open in the session when the crash happens? Any unicode / fancy symbol text in any of the panes?

Probably isn't be relevant but FYI: The current tmuxp seems to be v0.1.0rc2 according to the .virtualenvs/tmuxp/.

It turns out that I input the wrong parameter. I don't have a test session while I ran tmux freeze test.

After I sourced tmuxp.zsh, the available sessions are obviously shown up. In my case I should run tmuxp freeze 0.

Thanks for the help!

@leechannl Thank you. I can confirm that $ tmuxp freeze needs to give a more helpful error if session doesn't exist. I will follow up with a patch.

The freeze help message suggests it supports to freeze several sessions.

(tmuxp) tmuxp (master) ✗ tmuxp freeze -h
usage: tmuxp freeze [-h] [-L socket-name] [-S socket-path] [-y]
                    session_name [session_name ...]

But the result I got is not as expected.

(tmuxp) tmuxp (master) ✗ tmuxp freeze 0 1 3
args is Namespace(answer_yes=None, callback=<function command_freeze at 0x9036b8c>, colors=None, session_name=['0', '1', '3'], socket_name=None, socket_path=None)
session name are ['0', '1', '3']

I can confirm that the valid session names are 0 1 3 in my case.

@leechannl I committed a fix for this.

FYI at this point, $ tmuxp freeze only accepts 1 session at a time.

Can you try $ tmuxp freeze 0.

For future reference (in case anyone reads this): you can rename current sessions manually via Ctrl-b $ or Ctrl-a $ depending on the prefix key. The english version of the docs has this at http://tmuxp.readthedocs.org/en/latest/about_tmux.html#session-name. This page is not updated yet in 中文 docs.

v0.1.0rc5 is on pypi. Can you give this a try?

@leechannl I also confirm and additional issue - how CLI presents session names as if it allows multiple. I will make a second issue for this.
