Subject: bug#18637: 24.4.50; doc of frame parameter DISPLAY vs actual value on MS Windows
Date: Sun, 5 Oct 2014 12:23:34 -0700 (PDT)	[thread overview]
Message-ID: <12fc196e-cc82-4f22-8d2f-cede95542ea7@default> (raw)

In (elisp) `Basic Parameters' I see this description of frame parameter
`display':

  The display on which to open this frame.  It should be a string of
  the form `"HOST:DPY.SCREEN"', just like the `DISPLAY' environment
  variable.

But if I evaluate `(frame-parameters)' on MS Windows I see this value
for parameter `display': "w32".

"w32" does not seem to fit the form `"HOST:DPY.SCREEN"'.  What gives?

And why is that string surrounded by `...'?  And why aren't the
components of that "form" described: What are acceptable values for
HOST, DPY, and SCREEN?

(I assume that the `:' and `.' are to be taken literally here, and that
HOST, DPY, and SCREEN are placeholders, although there is zero
explanation of this.)

Also, I searched the manual case-sensitively for DISPLAY, and found no description/specification/explanation of "the `DISPLAY' environment variable.  So referring users to that env var to find a specification
of the form `"HOST:DPY.SCREEN"' is unhelpful and misleading.

Please clear up this doc - make it properly specify what form the value
of parameter `display' takes.
