[PATCH 0/4] a pile of misc improvements

I should send these out before I accidentally nuke my root FS
on accident, again :x

Eric Wong (4):
  archive: support comments, default to none
  splitfx: use Etc.nprocessors for jobs if unspecified
  dtas-console: set X11 terminal title iff DISPLAY is set
  dtas-console: add 'i' toggle to show comments (metadata)

[PATCH 1/4] archive: support comments, default to none

[Eric Wong]

The default "Processed by SoX" comment is pointless, and I often
want to archive + tag something in one step to reduce FS I/O.

[PATCH 2/4] splitfx: use Etc.nprocessors for jobs if unspecified

[Eric Wong]

We'll take advantage of multicore if available; because even
bums like me have SMP machines these days.

This allows users running terminals in graphical environments to
navigate to the terminal running dtas-console more easily.

[PATCH 6/4] doc: drop ordered map from examples

[Eric Wong]

"omap" is specific to Ruby and makes interopability with other
languages more difficult.

While it's true environment variables are stored as an ordered
array of C strings (see environ(7)); order doesn't matter in
practice.  Everyone in the real world treats the environment as
an unordered key-value store, and we shall follow.

  Perhaps consider testing for $WAYLAND_DISPLAY too?

  Use case: If, like me, you're running a wayland compositor without Xwayland
support then $DISPLAY won't be set.

Thanks,

James

Does the following work for you?

  Yes, thanks.

  FTR I’m running foot¹ on river², but other more common compositors like sway³
also support builds without Xwayland too.

  Bah, it always takes me a couple of messages to get back in the groove here.
Pinky swear I’ll set up a folder-hook before I send another mail.

No worries.  Also, Mail-Followup-To: isn't necessary for these types of lists.
(same convention for git@vger.kernel.org and various Linux kernel-related
 lists)
