From 2f6d9009af1df0f7cba1fdfe012a089babd8c747 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 3 Mar 2014 10:14:05 +0900 Subject: perf ui/tui: Reuse generic __hpp__fmt() code The __hpp__color_fmt used in the TUI code can be replace by the generic code with small change in print_fn callback. And it also needs to move callback function to the generic __hpp__fmt(). No functional changes intended.
