Change the colors

When output is directed to an ANSI terminal, zprint will colorize both code and structures output. I does this with a color map in the options map.

The default color map:

 :color-map {:brace :red,
             :bracket :purple,
             :comment :green,
             :deref :red,
             :fn :blue,
             :hash-brace :red,
             :hash-paren :green,
             :keyword :magenta,
             :nil :yellow,
             :none :black,
             :number :purple,
             :paren :green,
             :quote :red,
             :string :red,
             :syntax-quote-paren :red,
             :uneval :magenta,
             :user-fn :black},

If you want to change the colors, simple remap something. For example, to change the color of parentheses from the default green to black (for only this call to zprint):

(czprint-fn defn {:color-map {:paren :black}})

You can of course change it permanently by placing the change (in this case {:color-map {:paren :black}}) in an options map that is used for configuration, like ~/.zprintrc.

Unevaluated code

When zprint finds the symbols #_ that mark unevaluated code, it changes the color map to:

:uneval {:color-map {:brace :yellow,
                      :bracket :yellow,
                      :comment :green,
                      :deref :yellow,
                      :fn :cyan,
                      :hash-brace :yellow,
                      :hash-paren :yellow,
                      :keyword :yellow,
                      :nil :yellow,
                      :none :yellow,
                      :number :yellow,
                      :paren :yellow,
                      :quote :yellow,
                      :string :yellow,
                      :syntax-quote-paren :yellow,
                      :uneval :magenta,
                      :user-fn :cyan}},

This highlights the unevaluated code. You can change any of these colors as well.

If you wish to change the colors permanently, you can place these options maps anywhere an options map is accepted.
