-- @module hilbish.abbr
-- command line abbreviations
-- The abbr module manages Hilbish abbreviations. These are words that can be replaced
-- with longer command line strings when entered.
-- As an example, `git push` can be abbreviated to `gp`. When the user types
-- `gp` into the command line, after hitting space or enter, it will expand to `git push`.
-- Abbreviations can be used as an alternative to aliases. They are saved entirely in the history
-- Instead of the aliased form of the same command.

}
--- Adds an abbreviation. The `abbr` is the abbreviation itself,
--- while `expanded` is what the abbreviation should expand to.
--- It can be either a function or a string. If it is a function, it will expand to what
--- the function returns.
--- `opts` is a table that accepts 1 key: `anywhere`.
--- `opts.anywhere` defines whether the abbr expands anywhere in the command line or not,
--- whereas the default behavior is only at the beginning of the line
-- @param abbr string
-- @param expanded|function string
