indent entire buffer

[Joe]

Hi,

Loving Ymacs!

I added this to my keybindings file:

"C-i": function() {
this.cmd("mark_whole_buffer");
this.cmd("indent_region");
},

It marks the entire buffer, but it doesn't indent the region. Any
idea why?
Ideally I'd like a command to indent the buffer without having to mark
the entire buffer but I don't know if there is a command for that.

Also, if I set the mark and I move the cursor around, the region that
is created doesn't get the different background so that I can see what
is delineated as the region as I scroll around. Is there a setting
to show the region's background color after setting a mark and moving
the point around?

thanks,
-joe

When called interactively, indent_region receives automatically the
begin/end position of the region. When calling it with this.cmd, you
need to supply these arguments manually. For your case the following
should do:

this.cmd("indent_region", 0, this.getCodeSize());

(and there's no need to call mark_whole_buffer).

Nope, but it can be easily defined, for example:

Ymacs_Keymap_Emacs().defineKeys({
"C-=": Ymacs_Interactive("m", function(mark) {
if (!this.transientMarker) {
this.transientMarker = this.createMarker(mark);
this.ensureTransientMark();
}
})
});

Sorry for the general lack of API docs. :-(

Sweet! works great. thanks!

Thanks. but is there a way to have it work without hitting a key such
as C-= every time you move the point to see the region?
So if a mark is set and the point is different from the mark, the
region is highlighted, even as it changes. Kind of like S-ARROW_UP, S-
ARROW_DOWN work. The difference being that it only highlights if the
mark is set and doesn't set one itself. My regular emacs works that
way, i think from:
;; highlite the selected region
(setq-default transient-mark-mode t)

Not yet; that's because movement commands without SHIFT by default
clear the transient mark. I thought that whoever uses C-SPACE to set
the mark is used to not have it highlighted anyway (since Emacs early
days :).

ya. well it's not a big deal, transient-mark-mode is pretty new to me,
and I lived without it for years :-)

Oh, I just noticed a potential bug: If you load up a sizable file
such as ymacs.js and then set the indentation level to 2. and then try
to indent the entire buffer (either by marking the whole buffer and
indent_region or by your new way), it doesn't indent anything. I get
a progress indicator on the status bar, it goes to 100% but nothing
gets indented. I can select portions of the file and indent that
however.
I tried both firefox and chrome and got the same result.

I pushed a few minor changes including a fix for this. Updated the
demo and the latest.tar.gz too.
