We currently use the old systemd syntax that was copied from
getty@.service. It doesn't allow enabling specific TTYs, though. So use
the new WantedBy syntax instead.

We need to correctly set the VTNR for each new pty, otherwise the pty
cannot set the XDG_VTNR correctly. Note that we do this only for real VTs,
that is, vtnr > 0.
Signed-off-by: David Herrmann <dh.herrmann@gmail.com>
A caller can now pass a VT-num to the PTY which will get set as XDG_VTNR
in the environment of new childs.
This can be used to tell systemd-logind to associate the session with
the correct VT. But note that this still cannot overwrite VT-associations
if the pty is created from within an existing session.

Wayland compositors are not required to send buffer release notifications
on an implicit buffer-attach. That is, an attach->commit->commit series
does not cause a buffer-release notification after the second commit.
Hence, send a buffer-attach on every commit that requires a new
buffer-release notification.
For the related wayland-protocol changes, see:
http://cgit.freedesktop.org/wayland/wayland/commit/?id=7165bf21917ed1c4f5ec823a1e1642a9e83aa984
This fixes a bug where wlterm only redraws the window-content when
resizing (due to explicit buffer-attach calls during redraw).

This moves the description of kmscon.conf to a separate "Configuration"
section and adds some example kmscon.conf configuration lines.
This addresses #71 (at least, with this change in place I probably would
not have been momentarily confused by the exact syntax used in
kmsconf.conf).

This adds an --xkb-keymap <FILE> option to kmscon. When given, kmscon
will try to compile the keymap from the file before trying the other
options (like the XkbKeymap option in xorg.conf).
This is useful for users who have a customized XKB keymap, which is
usually kept in a single file. Example, in X:
xkbcomp $DISPLAY my_keymap.xkb
Customize my_keymap.xkb to your liking, and then in .xinitrc, or
xorg.conf:
xkbcomp my_keymap.xkb $DISPLAY
Now you can also do this in kmscon.conf.
Additionally, lacking such an option, kmscon is quite difficult to use
without an installed xkeyboard-config package, which provides the
infrastructure for the "rules" configuration mechanism. We might even
want to distribute some plain xkb file as a last ditch, for
robustness, if even the default RMLVO fails... without a keyboard a
terminal is not very useful.

This implements two new keyboard shortcuts zoom-in and zoom-out that

If the terminal screen is smaller than the real screen, we never paint to
the margins. This doesn't hurt as long as we never resize the terminal.
The uterm layer clears all framebuffers during allocation.
However, uterm behavior may change and our terminal may get resized (eg.,
during hotplugging) so we really should clear all the margins.
We now clear them on every frame as it is a trivial task. However, if we
speed up rendering, we should probably set a "needs_clear" flag that
simply clears the framebuffer.

We currently retrieve one font object per screen (which is in fact shared
in the font-layer), but we can also move it one layer up to the terminal
layer. This shares the same font per terminal between all screens.
This simplifies on-the-fly font modifications and speeds up monitor
hotplugging.

pango_ft2_render_layout_line() requires the baseline offset as argument,
not the vertical extent of the glyphs. This is important as we currently
align glyphs to the bottom edge instead of the baseline.
Fix this by passing the cached baseline offset so all glyphs are correctly
aligned to the baseline. We then clip according to the cell-extents as
usual.

It is currently pretty annoying to use multiple wlterm windows stacked on
top on each other when the terminal-background is black. The border
doesn't use multiple colors so it is hard to distinguish from the
main-frame.
This patch changes the border color to white (as most terminal-backgrounds
are black by default) and additionally draws a black 1px frame around it.
This guarantees that the frame is even visible with white terminal
backgrounds.

The ld.gold linker doesn't provide --format=default but needs --format=elf
instead. However, this doesn't work with ld.bfd. To avoid any linker
detection, we now link any binary file via partial-linking into a proper
object file itself and then link this object file in the final linking
step.
This also produces a fake libtool *.lo file so the libtool linking command
doesn't complain about PIC/non-PIC problems.

These ioctls are used to retrieve and set the VT-mode. That is, the
signals and PID information that correspond to the VT controlling process.
It is notified whenever the VT gets active/inactive so it can react to it

Session IDs provide a unique ID for each registered session. They are used
to sort the sessions so next/prev return the correct neighbour-sessions.
Furthermore, they can be used by outside users to refer to a session
directly without knowing the session implementation.
Sessions with ID=0 are always linked at the end and considered to be
"unnamed".
The algorithm to switch to a session with a given ID is:
Try to find the first session with the exact same ID. If there is none,
return the session with the next higher ID. If there is none, return the
ID'th session in the list. If there is none, return the last session.
This provides a fairly predictable way of switching between session. It is
modeled after the classic VT F1-F12 keys that switch between sessions. If
a session is not given, these keys will switch to the next higher session
instead.
All "unnamed" sessions are put at the end. So if you have only F1-F4, then
F5-F12 will map to unnamed sessions.
Please note that new sessions are always linked at the end of their group.
So new unnamed sessions are at the far end, new named sessions are linked
in the sorted list but behind all sessions with the same ID.
Hence, the caller should avoid multiple sessions with the same ID,
otherwise, some sessions might not be reachable even though they're named
(unless you use next/prev of course).

We should let the user move or resize the window while it is fullscreen or
maximized. This depends on the compositor to stop pending move/resize
requests when maximizing or setting a window fullscreen.
We can implement some "snap away from edges" behavior that allows to move
or resize while maximized. This will "unmaximize" the window if you move
it more than a given threshold. However, that's not needed now so lets do
that later when the wl_shell system is fully figured out.

A terminal's GL and GR sets can be mapped to 4 different registers g0 to
g3. The g0-g3 registers can be freely set by the application to predefined
or uploaded character-sets.
We implemented GL and GR as separate registers that are set to the current
g0-g3 states when the applications requests a remapping. So subsequent
changes to g0-g3 don't affect GL and GR. Unfortunately, it turns out this
is wrong. GL and GR should point to the g0-g3 registers instead of copying
them.
This commit fixes the GL and GR pointers to point to g0-g3 instead of
pointing to the underlying character sets. This fixes line-drawing
applications like alsamixer, make-menuconfig and other ncurses based
software.

We now create a VT for each legacy node and assign all clients to it. For
control nodes, we create a different VT for each open-file/client.
Note that we do not recreate VTs or CDEVs directly on HUP instead of
during the next open() or reconfiguration. This avoids trapping into the
same error again and gives control to the user to recreate the nodes at

The VT subsystem manages the virtual VTs and registers them with the

This is kmscon-7. See ./NEWS for a list of new features.
Unfortunately, github disabled the "Downloads" section so there is no way
to upload new pre-generated tarballs. I have a pending application to move
kmscon to freedesktop.org, but it didn't get processed in time for this
release. Therefore, you need to build the GNU-autotools files yourself.
That is, before calling ./configure you need to call:
NOCONFIGURE=1 ./autogen.sh
You can extend your build-scripts with:
test -f ./configure || NOCONFIGURE=1 ./autogen.sh
Which will call ./autogen.sh if needed. Everything else can be left
unchanged.
I will not upload the tarballs at another location. Feel free to do that
yourself, but I personally think this will introduce more confusion than
help. I hope the freedesktop.org move will be soon approved. This will
also provide a mailing-list where I can properly announce new releases.
Raw tarballs will be available as (without pre-generated autotools):
https://github.com/dvdhrm/kmscon/archive/kmscon-7.tar.gzhttps://github.com/dvdhrm/kmscon/archive/kmscon-7.zip
The git-tag is: kmscon-7
