Cursive has a repl powered debugger just put your breakpoint there use the repl to trigger the call then use intellji's debugger to step through If you want to run expressions in context just use the expression editor like a normal repl Something I haven't tried yet is redefining functions at debug time can't see why it wouldn't work though
