Make FZF_TMUX_OPTS default behavior

[joshmedeski]

When setting FZF_TMUX_OPTS all uses of fzf-tmux don't recognize the options set unless explicitly passed into the command:

fzf-tmux $FZF_TMUX_OPTS

Why is this? Can this be rewritten so anytime someone calls fzf-tmux the options are read and used?

fzf-tmux # automatically use FZF_TMUX_OPTS

FZF_TMUX_OPTS is currently only used by shell extensions, i.e. key bindings and fuzzy completion. The existence of the variable tells the scripts to use fzf-tmux instead of starting fzf with the --height option. So no, the variable wasn't designed to be used by fzf-tmux.

Anyway, I think your suggestion makes sense, although we can ignore the possibility that there are users who don't want it to affect their fzf-tmux outside of the shell extension context.

We could create a new FZF_TMUX_DEFAULT_OPTS variable that works similarly to FZF_DEFAULT_OPTS.

Then, we wouldn't have to worry about communicating a breaking change on the previous variable.

For now, I'm going to do something similar to what your doing on the key-binding and fuzzy completion logic to detect that variable manually.

As an alternative, you can define a function of the same name like so:

fzf-tmux() {
  command fzf-tmux -p 80% "$@"
}

Alright, it sounds like you'd prefer putting the responsibility on the user to use FZF_DEFAULT_OPTS or not.

I'm okay with that and I'll be integrating FZF_DEFAULT_OPTS support into my script, thanks.
