This patch adds a new flag called history_dirty to Line::Editor that is
set when history is added to but written. Applications can leverage
this flag to write history only when it changes. This patch adds an
example usage of this functionality to Shell, which will now only save
the history when it is dirty.
The current implementation is missing the emphasized text of the
following rule in the painting order spec:
7. Otherwise: *first for the element*, then for all its in-flow,
non-positioned, block-level descendants in tree order...
This ensures the foreground is painted for the current element before
descending into its children.
Instead of having the window non-resizable, it now defaults to a frame
size of 200 x 200 pixels but is user-resizable. The shown screenshot
updates its size accordingly. :^)
Sometimes we might need a larger view, or a non-square shape.
This commit implements glGenLists(), glNewList(), glDeleteLists(), and
glCallList().
The 'compiled' records are implemented as a vector of member function
pointers and tuples containing their arguments, and a mechanism is
implemented to allow the recorded calls to copy-capture values from the
time of the call; this is currently only used with glLoadMatrix.
This allows the construction of `Variant<int, int, int>`.
While this might not seem useful, it is very useful for making variants
that contain a series of member function pointers, which I plan to use
in LibGL for glGenLists() and co.
typeid() and RTTI was a nice clutch to implement this, but let's move
away from the horrible slowness and implement variants using type
indices for faster variants.
This cuts a region of a bitmap specified by the provided Gfx::IntRect
and returns it. Areas outside of the bounds of the original bitmap are
filled in with black.
With this fixed dlopen() no longer crashes when given an invalid
ELF image and instead returns an error code that can be retrieved
with dlerror().
Fixes#6995.
Previously we'd try to load ELF images which did not have
an interpreter set with an incorrect load offset of 0, i.e. way
outside of the part of the address space where we'd expect either
the dynamic loader or the user's executable to reside.
This fixes the problem by using get_load_offset for both executables
which have an interpreter set and those which don't. Notably this
allows us to actually successfully execute the Loader.so binary:
courage:~ $ /usr/lib/Loader.so
You have invoked `Loader.so'. This is the helper program for programs
that use shared libraries. Special directives embedded in executables
tell the kernel to load this program.
This helper program loads the shared libraries needed by the program,
prepares the program to run, and runs it. You do not need to invoke
this helper program directly.

You can now watch the clipboard for changes and run a command each time
the clipboard contents change like this:
$ paste --watch some command here
The command will be spawned each time the clipboard contents change. It
can read the clipboard contents from its stdin, and CLIPBOARD_STATE
environment variable will be set to "data" if there is data to be read,
or to "nil"/"clear" if the clipboard has been cleared.
With those partially implemented I can start to clone the SerenityOS
git repository via HTTPS.
The download still fails half-way through because SSL_read returns
an error for reasons I haven't investigated yet.
Previously we'd incorrectly use the default gateway's MAC address.
Instead we must use destination MAC addresses that are derived from
the multicast IPv4 address.
With this patch applied I can query mDNS on a real network.
This patch changes the validation of RegExp flags (checking for
invalid and duplicate values) from a SyntaxError at runtime to a
SyntaxError at parse time - it's not something that's supposed to be
catchable.
As a nice side effect, this simplifies the RegExpObject constructor a
bit, as it can no longer throw an exception and doesn't have to validate
the flags itself.
Okay we've tried this twice now, and nobody ends up working on it.
Meanwhile, more and more people are using GML, and I think it's safe
to say that GML is the future of GUI development here.
So let's get rid of the old form editor from HackStudio and pave the
way for integrating GML editing into the IDE instead. :^)
Reapply the app icon if the we are coming back from "frameless" mode.
This will re-initialize the icon representing the app in the task bar,
instead of displaying the default application icon.
This bug was visible in "Cube Demo" as well as the "Analog Clock".
Introduce the ability to hide the Analog Clock window borde. With this
feature enabled it looks like the clock is floating and integrated into
the desktop.
The "Cube Demo" has the same feature, and was used as inspiration when
implementing the feature in the Analog Clock.
