vim Configuring Vim Variables
Example
Like most scripting languages, vimscript has variables.
One can define a variable with the :let command:
let variable = value
and delete it with :unlet:
unlet variable
In Vim, variables can be scoped by prepending a single letter and a colon to their name. Plugin authors use that feature to mimic options:
let g:plugin_variable = 1
See :help internal-variables.
