Running chips should reload the configuration

[xtendo-org]

Currently running chips is not sufficient to update the plugin system; it doesn't load the new plugins to the current fish shell which ran chips. The shell will remain unchanged.

Let's say the desired use-case scenario is that the user types chips, then the install/update takes place, and the current shell is loaded with the latest configuration and plugins. This means:

• The executable file needs to call the exec* family of functions to replace itself with fish.
• Fish needs to execute chips by exec chips, not just chips.

So, we need to add, at the end of the chips source code, a line that calls exec*. Then, in the build.fish file, something like below:

alias chips "exec ~/.local/bin/chips"

Alternatively, we can simply drop the line below in build.fish:

alias chips "~/.local/bin/chips; exec fish"

I really like the second option. With this, I don't even need to add the ~/.local/bin to my $PATH variable!

alias chips "~/.local/bin/chips; and exec fish"
