This helper reads the current expiration-count from a timer. This can be
used when waking up from an idle-period or similar to reset the timer.

We already have an llog context so use it instead of relying on kmscon-log
subsystem. TSM-screen is now fully independent. Next step is TSM-vte.

Instead of accessing kmscon state from TSM, we now introduce options to
control the behavior of TSM-screens. Apart from logging, TSM is now
independent of any kmscon state/code.

Allow setting global options for screen objects. These are different from
flags as the latter affects the state-machine but options affect global
operation modes.
Options should be set by the application while flags are set by the VTE
handler. The latter might change often, while options should be set on
startup and then remain mainly constant.

This is no longer used. You should first retrieve the UCS4 string and then
use the UCS4 to U8 conversion helpers instead.
All users have already been converted so we can remove this helper safely.
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
Instead of converting symbols into UCS4 string in each backend, we now
pass the whole data from the console layer into the renderers.
This makes all renderers indepedent of any recently introduced
symbol-tables and they can be implemented inside of TSM without exporting
them. However, we still need to pass the IDs to the text layer. The text
layer must not use them for anything but identification. Moreover, it must
never assume that they are valid tsm_symbol_t values.
We do this so the backends can still have fast hashtable lookups rather
than allocating big keys containing the UCS4 string+length and using these
for lookups.
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
This small helper allocates a string big enough to hold the whole u8
string. This should be used for short and temporary strings only! It
allocates way to much memory for bigger or long-living strings.

We really need xkbcommon-keysyms.h for building kmscon/uterm/TSM/etc.
However, the recent fix was ugly and didn't really help. Instead we copy
the keysyms file into external/xkbcommon/ so we can just include the real
xkbcommon files from any source but have a fallback in external/.
Hence, you can still build kmscon without xkbcommon with this fallback,
but this will be removed the first day when xkbcommon sees a public
release.

This helper function may be useful to other external code and allows us to

We should avoid any global state in shared libraries. As the TSM code is
becoming a shared library, we definitely need contexts for symbol tables.
However, we don't want to fix up all code now so we use a default table
NULL instead.
This can be fixed later but is ok for now.

We changed the PPI value to 96 so the default font size looks abnormally
large now. Reset it to the previous value of 12 so it is more "normal".
Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
This adds a new option to force a global PPI for all fonts. This overrides
per monitor PPI values.
This is useful if monitors do not provide correct PPI values and we want
the same behavior as all other X11 apps (which is 96 PPI forced).
Internally we speak of "Pixels per Inch" as this is more correct. However,
to not confuse users we use the more common term "Dots per Inch".
This also changes the default PPI value from 72 to 96. 96 is the de-facto
default value on linux so we should use it, too.

If Shift is hold while F4 to F20 is pressed, a second parameter is added

No DEC-VT-manual seems to describe this feature, however, nearly all
terminal emulators stop parsing OSC strings when receiving a BEL
character. So add this to the normal ST character to terminate OSC
strings.

XTerm's altSendsEscape resource controls whether an escape character is
prepended to any output that is generated by keyboard input. We enable it
by default now.
Keyboard handling becomes kind of ugly now in the VTE layer. We should
definitely change this into some kind of lookup table or a more
sophisticated switch() handler in vte_input.c or similar.
Thanks to Tobias Wolf, "Etam" and Ran Benita for reporting this to the
bug-tracker and figuring out how this is correctly handled.

Instead of requiring to use uterm_screen objects we now add a
