Why? I'm not saying they aren't, just curious about the lack of an
explanation as to why they would be. Please add it to this changelog
comment.

BTW, I applied [1,2]/7 already.

The "_context" looks superfluous, why not just "perf_hpp" or just "hpp"
since probably this won't be exposed in any library outside perf itself,
right?
Also please separate the struct name from the method using __, as in
other perf classes.
So it would be:
static int hpp__header_overhead(struct hpp *hpp)
As 'ctx' also doesn't add any cue as to what it is, just like 'self',
that I've been removing over time.

So that inc is the number of characters printed...

's' is the number of characters printed? Looks like

Humm, so we'll need to have this exposed here because you'll implement
gtk equivalents?

Using 'perf_" to separate namespaces seems required, as we'll be mixing
this with gtk stuff (qt or whatever at some point if anybody
volunteers).
But I think hist_period_print should be hpp_fmt and hpp_context renamed
to hpp_buffer or hpp_bf.

Ok, let me try it like below:
Current hist print functions are messy because it has to consider many
of command line options and the code doing that is scattered around to
places. So when someone wants to add an option to manipulate the hist
output it'd very easy to miss to update all of them in sync. And things
getting worse as more options/features are added continuously.
So I'd like to refactor the using hpp callbacks and move common code to
ui/hist.c in order to make it easy to maintain and to add new features.

When a field separator is given, the output format doesn't need to be
fancy like aligning to column length, coloring the percent value and
so on. And since there's a slight difference to normal format, fix it
not to break backward compatibility.

Override hpp->color functions for TUI. Because line coloring is done
outside of the function, it just sets the percent value and pass it.

Maybe. I agree that general ui code reside on ui/ and front-end
specifics should go to their subdirectories. But not sure for the stdio
case since they'll have very simple code only.
For this case, most of functions would be converted to manipulate a
string buffer like scnprintf and shared by all front-end's as long as
possible - callchain print code needs some more working. But if you
want, I'll separate out actual fprintf's to ui/stdio/.
Thanks,
Namhyung
