Custom directory name per plugin

[L1Q]

Context

Some plugins would name their repository not after the plugin, but after the app, notably catppuccin/tmux
Their install instructions recommend using tpm like this

set -g @plugin 'catppuccin/tmux'

This results in the following folder path ~/.tmux/plugins/tmux.
Not very descriptive and potentially even conflicting.

Git can already clone a repository into a custom target directory

git clone https://github.com/tmux-plugins/tmux-open.git ~/.tmux/plugins/open

Right now, tpm would not recognize the ~/.tmux/plugins/open as a valid tmux-open installation.

Suggestion

• Add a form of syntax where custom directory name can be provided for a plugin

set -g @plugin 'catppuccin/tmux' 'catppuccin'

• Allow tpm to search for the installed plugins in the custom directory, install, update and remove them accordingly.

I just got bit by this, too! This would be lovely.

I think #217 will fix this issue (if merged).

I got bit this! I wanted to switch from catppuccin/tmux to dracula/tmux but when I <prefix>+I, the dracula plugin just wouldn't get installed. Then I looked into ~/.config/tmux/plugins and found that the catpuccin theme was in the tmux folder. I deleted this folder and only then did dracula get installed, also at the tmux folder! So plugins are not namespaced by the github username; the repo names are essentially global.

@mebble thank you for leaving that comment, this fixed an issue I was having which I was pulling my hair out over

Would be fantastic if #217 could get merged
