# *doc-width* is bound to the keyword :doc-width - it can be used in place of # :doc-width in a call to `dyn`, `setdyn`, or `with-dyns` and is preferable # to using the keyword directly. When set to a number, it indicates the # maximum width (in columns) of a row of text returned by `doc-format`. # - Like *doc-color*, *doc-width* can be used to adjust the output of # `doc-format`. # - When the :doc-width dynamic binding is not set, the default width is 80. # - By default, `doc-format` adds 4 space indentation and subtracts 8 from # the value of the :doc-width dynamic binding to calculate a max width. # Default: # repl> (doc doc) # # # macro # boot.janet on line 3573, column 1 # # (doc &opt sym) # # Shows documentation for the given symbol, or can show a list of # available bindings.
