This patch re-arranges nitpicker's graphics backend in a more modular
and expandable way. Generalized versions of the 'Canvas',
'Chunky_canvas', and 'Pixel_*' classes have been moved to
'os/include/util/' and 'os/include/os'. The only remaining parts that
are specific to nitpicker's needs are a few drawing functions, each
located in a distinct header at 'os/include/nitpicker_gfx/'.
Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.
This patch moves the further reusable parts of the terminal into public
header files. It also slightly tweaks the color table to give all colors
a similar brightness level.
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.
Hereby, the base libraries have been reduced to the following few
libraries:
- startup.mk contains the startup code for normal Genode processes.
On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
processes
Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.
Fixes#18
This patch introduces keyboard-focus events to the 'Input::Event' class
and changes the name 'Input::Event::keycode' to 'code'. The 'code'
represents the key code for PRESS/RELEASE events, and the focus state
for FOCUS events (0 - unfocused, 1 - focused).
Furthermore, nitpicker has been adapted to deliver FOCUS events to its
clients.
Fixes#609
Set the right bg color instead of using a dimmed version of the fg
color. The colors are stored in the first 6 bits of the color index.
Thereby the first 3 bits contain the fg and the second 3 bits the
bg color.
The debug message in _handle_esc_seq5() now shows the sequence in
question.
Fixes#495.
The terminal has a lot of bits that may be worth reusing outside the
single implementation. Those bits are now located at 'include/terminal'
in the gems repository.
sgr0 is currently implemented as a wrapper of sgr(0) which
seems to work fine.
For now we accept but ignore certain sgr sequences like for
example [0;10;1m which is generated by lynx even when using
TERM=linux (I am not sure yet if that's actually valid at all).
Though the initial commit contains nicer looking color definitions
it is easier to spot wrong colors when using a program that uses
ncurses like for example lynx.
Fixes#284.
This patch increases the stack size of entrypoint threads in the PCI and
PS/2 drivers, in the Terminal server and in the Signal service for 64-bit
Genode/Fiasco.OC built with -O0.
Fixes#198.
As a preliminary step for working on issue #11, this patch revisits the
'Framebuffer::info' RPC call. Instead of using C-style out paramters,
the new 'mode()' RPC call returns the mode information as an object of
type 'Mode'. Consequently, mode-specific functions such as
'bytes_per_pixel' have been moved to the new 'Framebuffer::Mode' class.
This patch changes decouples the conversion of the terminal state to
pixels from the write RPC function. Intermediate terminal states
produced by sub sequential write operations do not end up on screen one
by one but only the final state becomes visible. This drastically
improves the speed of scrolling through large text output.
