CIDER can syntax highlight symbols that are known to be defined. By default,
this is done on symbols from the
clojure.core namespace, as well as macros
from any namespace. If you’d like CIDER to also colorize usages of functions
and variables from any namespace, do:
(setq cider-font-lock-dynamically '(macro core function var))
Here’s how code looks without dynamic syntax highlighting.
And here’s how to the code looks when it’s turned on.
By default CIDER will apply font-locking to unused reader conditional expressions depending on the buffer CIDER connection type.
You can disable this behavior by adjusting
(setq cider-font-lock-reader-conditionals nil)
CIDER defines a few custom faces that you might want to adjust (although normally your color theme should take care of them):
cider-deprecated-face- used for syntax highlighting deprecated vars
cider-instrumented-face- used for syntax highlighting instrumented for debugging vars
cider-traced-face- used for syntax highlighting traced vars
cider-reader-conditional-face- used for syntax highlighting inactive reader conditional branches
