A *fishfile* lets you share plugin configurations across multiple installations, allows plugins to declare dependencies, and prevent information loss in case of system failure.
To read fishfiles use `fisher --file=fishfile`. This will read *fishfile* sequentially, writing its contents to the standard output. oh-my-fish bundle files are supported as well.
If *fishfile* is null or an empty string, the global *fishfile* in `$fisher_config/fishfile` will be used. Use a dash `-` to force read from standard input.
Plugins may declare any number of dependencies to other plugins in a fishfile at the root of their project.
By default, when Fisherman installs a plugin, it will also fetch and install its dependencies. If a dependency is already installed, it will not be updated as this could potentially break other plugins using an older version. For the same reason, uninstalling a plugin does not remove its dependencies.
To understand this behavior, it helps to recall the shell's single scope for functions. The lack of private functions means that, it is *not* possible to single-lock a specific dependency version. See also `Flat Tree` in `fisher(7)`.
