Why are parenscript functions changed to all lowercase?

Question

When using parenscript if I execute

(parenscript:ps 
 (slot-value ($ "#mytextarea") 'selectionStart))

It produces the javascript

$('#mytextarea').selectionstart;

Note that selectionStart is now selectionstart. It lost the uppercase S on the Start! How do I keep that uppercase S around?

Answer 1

Parenscript will automatically convert from the lisp naming convention (dashes separating words) to CamelCase, so:

(parenscript:ps 
 (slot-value ($ "#mytextarea") 'selection-start))

results in

"$('#mytextarea').selectionStart;"
