You can now #include <AK/Forward.h> to get most of the AK types as
forward declarations.
Header dependency explosion is one of the main contributors to compile
times at the moment, so this is a step towards smaller include graphs.
This patch implements basic drag & drop file management in a narrow set
of cases. You can now drag & drop a file onto a folder in the same
directory, and the dropped file will be copied into the directory.
We'll need to support a lot more variations of this, but this is nice!
This commit adds basic support for importing, viewing and playing WAV
samples at different pitches.
Naming issues:
- We are using the Sample struct from Music.h, but also the Sample
struct from LibAudio (Audio::Sample). This is a little confusing.
set_recorded_sample() finds the peak sample and then divides all the
samples by that peak to get a guaranteed min/max of -1/1. This is nice
because our other waves are also bound between these values and we can
just do the same stuff. This is why we're using Audio::Sample, because
it uses floats, whereas Music.h's Sample uses i16s. It's a little
annoying that we have to use a mixture of floats and doubles though.
For playback at lower frequencies, we're calculating in-between samples,
rather than just playing samples multiple times. Basically, you get the
current sample and add the difference between the current sample and the
next sample multiplied by the distance from the current sample. This is
like drawing the hypotenuse of a right-angled triangle.
This was only used by HashTable::dump() which I used when doing the
first HashTable implementation. Removing this allows us to also remove
most includes of <AK/kstdio.h>.
This is not a bug currently, since the first column immediately starts
playing at startup and leaves no time for the user to put notes in it.
However, this is needed for exporting.
The piano roll data definitely belongs in AudioEngine along with the
note and time data. Now RollWidget only has GUI information, much like
the other widgets.
Note that this commit exacerbates issue #1158 which is caused by
RollWidget::paint_event().
I started adding things to a Draw namespace, but it somehow felt really
wrong seeing Draw::Rect and Draw::Bitmap, etc. So instead, let's rename
the library to LibGfx. :^)
This makes getting a pseudoterminal pair a little bit more portable.
Note that grantpt() and unlockpt() are currently no-ops, since we've
already granted the pseudoterminal slave to the calling user.
We also accept O_CLOEXEC to posix_openpt(), unlike some systems. :^)
FileUtils.cpp:131:34: error: cannot pass object of non-trivial type 'const AK::String' through variadic method; call will abort at runtime [-Wnon-pod-varargs]
Notice that we are calculating release time according to the level when
the note is turned off rather than the sustain level. Naively using the
sustain level gives very long release times if you turn the note off
during attack, whereas this deterministically gives the same release
time.
1. Make decay sample-granular rather than buffer-granular
You only have ~43 buffers per second which can make a jagged signal.
2. Calculate decay in milliseconds
Decay is supposed to be a time value.
I say "phony" because it's not actually playing the same frequency
twice, it's just playing the same frequency at a higher volume. We can
properly implement this later but at the moment it'll get in the way of
our ADSR implementation.
Now you can change the defaults in AudioEngine and not be totally
confused.
1. The default for m_octave_knob was actually upside-down.
2. The default for m_decay_knob wasn't respecting AudioEngine.
3. The default for m_delay_knob wasn't respecting AudioEngine.
I've been wanting to do this for a long time. It's time we start being
consistent about how this stuff works.
The new convention is:
- "LibFoo" is a userspace library that provides the "Foo" namespace.
That's it :^) This was pretty tedious to convert and I didn't even
start on LibGUI yet. But it's coming up next.
Goals:
- Switch to a more typical LibGUI arrangement
- Separate GUI (MainWidget) and audio (AudioEngine)
- Improve on existing features while retaining the same feature set
Improvements:
- Each GUI element is a separate widget
- The wave (WaveWidget) scales with the window
- The piano roll (RollWidget) scales horizontally and scrolls vertically
- The piano (KeysWidget) fits as many notes as possible
- The knobs (KnobsWidget) are now sliders
- All mouse and key events are handled in constant time
- The octave can be changed while playing notes
- The same note can be played with the mouse, keyboard and roll at the
same time, and the volume of the resulting note is scaled accordingly
- Note frequency constants use the maximum precision available in a
double
When a single item is selected and it happens to be a symlink pointing
somewhere, we now show where it points to in the status bar. :^)
There is a big ugly FIXME here about how DirectoryView has to work
around the fact that there's a GSortingProxyModel attached to the table
view widget.
This changes copyright holder to myself for the source code files that I've
created or have (almost) completely rewritten. Not included are the files
that were significantly changed by others even though it was me who originally
created them (think HtmlView), or the many other files I've contributed code to.
A process has one of three veil states:
- None: unveil() has never been called.
- Dropped: unveil() has been called, and can be called again.
- Locked: unveil() has been called, and cannot be called again.
Put each tool's thickness altering actions into a GActionGroup and make
them mutually exclusive so we get that nice radio button appearance.
This all feel very clunky and we should move towards having something
like a "tool settings" pane that gets populated by the currently active
tool instead.
I mistakenly thought that we were keeping the config file open, but we
don't. So we'll need to unveil the config path in case we need to write
out a new configuration.
This app needs ("/bin/Terminal", "x") in order to fork+exec itself when
the user requests a new Terminal window. I really like how this reduces
reduces the impact of pledging "exec". :^)
It also needs ("/res", "r") like all GUI apps. We delay the first call
to unveil until after we've already opened the app's config file, so
there's no need to worry about that.
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.
This patch adds a new "accept" promise that allows you to call accept()
on an already listening socket. This lets programs set up a socket for
for listening and then dropping "inet" and/or "unix" so that only
incoming (and existing) connections are allowed from that point on.
No new outgoing connections or listening server sockets can be created.
In addition to accept() it also allows getsockopt() with SOL_SOCKET
and SO_PEERCRED, which is used to find the PID/UID/GID of the socket
peer. This is used by our IPC library when creating shared buffers that
should only be accessible to a specific peer process.
This allows us to drop "unix" in WindowServer and LookupServer. :^)
It also makes the debugging/introspection RPC sockets in CEventLoop
based programs work again.
It was never updating because we'd just seek the start of /proc/memstat
over and over, which didn't generate new contents. Instead, open the
file on every iteration.
Now that the "unix" pledge is no longer required for socket I/O, we can
drop it after making the connections we need in a program.
In most GUI program cases, once we've connected to the WindowServer by
instantiating a GApplication, we no longer need "unix" :^)
This patch makes it so that if the find/replace widget is opened while
some text is selected, the find textbox's content is overrided with the
selected text.
This patch adds a new replace widget that cooperates with the find
widget, the replace widget takes the input in the find textbox, searches
for occurences of that input, and replaces them with the input provied
in the replace textbox.
This is the first complex app to use pledge(), and it was extremely
easy to get it working.
The main trickiness comes from the RPC sockets that get set up inside
the GApplication constructor. Since it wants to unlink any old RPC
socket with the same filename and change the file mode of the new
socket, it needs both "cpath" and "fattr".
Once the GApplication has been constructed, it seems we can safely
drop those promises. Pretty cool!
This new view, backed by a GColumnsView, joins the existing table and icon
views :^) Even though it displays a file tree, its data is provided by the very
same GFileSystemModel that the other two views use.
This commit also includes my attempt at making an icon for the new mode.
We used to have two different models for displaying file system contents:
the FileManager-grade table-like directory model, which exposed rich data
(such as file icons with integrated image previews) about contents of a
single directory, and the tree-like GFileSystemModel, which only exposed
a tree of file names with very basic info about them.
This commit unifies the two. The new GFileSystemModel can be used both as a
tree-like and as a table-like model, or in fact in both ways simultaneously.
It exposes rich data about a file system subtree rooted at the given root.
The users of the two previous models are all ported to use this new model.
I though it would be nice to also show the style that the browser uses
to display an element.
In order to do that, in place of the styles table I've put a tab widget,
with tabs for both element and computed element styles.
This means that (for example) if you change the line width of the line
tool, you now switch to the line tool, instead of sticking with the
currently "checked" tool.
When selecting an element in the browser's DOM inspector, we now also
show the resolved CSS properties (and their values) for that element.
Since the inspector was growing a bit more complex, I moved it out of
the "show inspector" action callback and into its own class.
In the future, we will probably want to migrate the inspector down to
LibHTML to make it accessible to other clients of the library, but for
now we can keep working on it inside Browser. :^)
The new PCI subsystem is initialized during runtime.
PCI::Initializer is supposed to be called during early boot, to
perform a few tests, and initialize the proper configuration space
access mechanism. Kernel boot parameters can be specified by a user to
determine what tests will occur, to aid debugging on problematic
machines.
After that, PCI::Initializer should be dismissed.
PCI::IOAccess is a class that is derived from PCI::Access
class and implements PCI configuration space access mechanism via x86
IO ports.
PCI::MMIOAccess is a class that is derived from PCI::Access
and implements PCI configurtaion space access mechanism via memory
access.
The new PCI subsystem also supports determination of IO/MMIO space
needed by a device by checking a given BAR.
In addition, Every device or component that use the PCI subsystem has
changed to match the last changes.
Threads now have numeric priorities with a base priority in the 1-99
range.
Whenever a runnable thread is *not* scheduled, its effective priority
is incremented by 1. This is tracked in Thread::m_extra_priority.
The effective priority of a thread is m_priority + m_extra_priority.
When a runnable thread *is* scheduled, its m_extra_priority is reset to
zero and the effective priority returns to base.
This means that lower-priority threads will always eventually get
scheduled to run, once its effective priority becomes high enough to
exceed the base priority of threads "above" it.
The previous values for ThreadPriority (Low, Normal and High) are now
replaced as follows:
Low -> 10
Normal -> 30
High -> 50
In other words, it will take 20 ticks for a "Low" priority thread to
get to "Normal" effective priority, and another 20 to reach "High".
This is not perfect, and I've used some quite naive data structures,
but I think the mechanism will allow us to build various new and
interesting optimizations, and we can figure out better data structures
later on. :^)
This is memory that's loaded from an inode (file) but not modified in
memory, so still identical to what's on disk. This kind of memory can
be freed and reloaded transparently from disk if needed.
Dirty private memory is all memory in non-inode-backed mappings that's
process-private, meaning it's not shared with any other process.
This patch exposes that number via SystemMonitor, giving us an idea of
how much memory each process is responsible for all on its own.
Palette is now a value wrapper around a NonnullRefPtr<PaletteImpl>.
A new function, set_color(ColorRole, Color) implements a simple
copy-on-write mechanism so that we're sharing the PaletteImpl in the
common case, but allowing you to create custom palettes if you like,
by getting a GWidget's palette, modifying it, and then assigning the
modified palette to the widget via GWidget::set_palette().
Use this to make PaintBrush show its palette colors once again.
Fixes#943.
Build them if they don't exist, but don't care about them being
newer or older than the target.
I believe this is what was causing build loops where IPCCompiler was
being run a second time, rebuilding its .h file, then a library
would depend on that .h file and get re-archived, then an
application would need relinking, and something in that whole
process would trigger IPCCompiler running again touching its .h
file.
Lock each directory before entering it so when using -j, the same
dependency isn't built more than once at a time.
This doesn't get full -j parallelism though, since one make child
will be sitting idle waiting for flock to receive its lock and
continue making (which should then do nothing since it will have
been built already). Unfortunately there's not much that can be
done to fix that since it can't proceed until its dependency is
built by another make process.
The tool currently supports drawing an elliptical line of a specified
thickness. Further improvements can include adding a fill mode, and
holding down shift to draw a perfect circle.
Closes#375.
Instead of directly manipulating LDFLAGS, set LIB_DEPS in each
subdirectory Makefile listing the libraries needed for
building/linking such as "LIB_DEPS = Core GUI Draw IPC Core".
This adds each library as an -L and -l argument in LDFLAGS, but
also adds the library.a file as a link dependency on the current
$(PROGRAM). This causes the given library to be (re)built before
linking the current $(PROGRAM), but will also re-link any binaries
depending on that library when it is modified, when running make
from the root directory.
Also turn generator tools like IPCCompiler into dependencies on the
files they generate, so they are built on-demand when a particular
directory needs them.
This all allows the root Makefile to just list directories and not
care about the order, as all of the dependency tracking will figure
it out.
GApplication now has a palette. This palette contains all the system
theme colors by default, and is inherited by a new top-level GWidget.
New child widgets inherit their parents palette.
It is possible to override the GApplication palette, and the palette
of any GWidget.
The Palette object contains a bunch of colors, each corresponding to
a ColorRole. Each role has a convenience getter as well.
Each GWidget now has a background_role() and foreground_role(), which
are then looked up in their current palette when painting. This means
that you no longer alter the background color of a widget by setting
it directly, rather you alter either its background role, or the
widget's palette.
Color themes are loaded from .ini files in /res/themes/
The theme can be switched from the "Themes" section in the system menu.
The basic mechanism is that WindowServer broadcasts a SharedBuffer with
all of the color values of the current theme. Clients receive this with
the response to their initial WindowServer::Greet handshake.
When the theme is changed, WindowServer tells everyone by sending out
an UpdateSystemTheme message with a new SharedBuffer to use.
This does feel somewhat bloated somehow, but I'm sure we can iterate on
it over time and improve things.
To get one of the theme colors, use the Color(SystemColor) constructor:
painter.fill_rect(rect, SystemColor::HoverHighlight);
Some things don't work 100% right without a reboot. Specifically, when
constructing a GWidget, it will set its own background and foreground
colors based on the current SystemColor::Window and SystemColor::Text.
The widget is then stuck with these values, and they don't update on
system theme change, only on app restart.
All in all though, this is pretty cool. Merry Christmas! :^)
m_roll_notes[] is an array of 2 bools, pressed and playing. A roll note
is highlighted if it is pressed or in the currently playing column, but
the note is only actually played if the roll note is both pressed and
playing.
We change columns every m_tick which is currently 10 frames. The delay
is synchronised with this. change_roll_column() tracks the previous
column and current column to be played. Each roll note in the previous
column is set to "not playing" and the underlying audio note is turned
off if it was pressed. For the current column, each roll note is set to
playing and the underlying audio note is turned on if pressed.
Rather than checking key codes and mouse positions, we should have a
more general way to play notes. You can call note() either with a
KeyCode or a PianoKey directly.
Additionally, m_note_on[] is now an array of integers instead of bools.
This allows multiple sources to play a note. This is kind of like a
"reference counted note": two sources can increment the note and it will
only turn off once they have both decremented it back to 0.
We are now only using keys[] to prevent multiple consecutive calls to
keydown_event() (when a key is held), since that would result in playing
a note many times.
Allow everything to be built from the top level directory with just
'make', cleaned with 'make clean', and installed with 'make
install'. Also support these in any particular subdirectory.
Specifying 'make VERBOSE=1' will print each ld/g++/etc. command as
it runs.
Kernel and early host tools (IPCCompiler, etc.) are built as
object.host.o so that they don't conflict with other things built
with the cross-compiler.
We now try to open image files dropped on us from FileManager. :^)
The QuickShow code is not exactly well-factored, and should be fixes up
to not do the same thing twice, etc.
Every process keeps its own ELF executable mapped in memory in case we
need to do symbol lookup (for backtraces, etc.)
Until now, it was mapped in a way that made it accessible to the
program, despite the program not having mapped it itself.
I don't really see a need for userspace to have access to this right
now, so let's lock things down a little bit.
This patch makes it inaccessible to userspace and exposes that fact
through /proc/PID/vm (per-region "user_accessible" flag.)
The squad is complete :^)
You can find the equation for the triangle wave here:
https://en.wikipedia.org/wiki/Triangle_wave
We're using this one:
|x mod 4 - 2| - 1
Modifications have been made to correct the frequency and phase:
|(4x + 1) mod 4 - 2| - 1
The white noise is generated by calling rand() and dividing it by
RAND_MAX to get a value from 0 to 1. Then it's adjusted to fit between
-1 and 1.
This adds a context menu to the TreeView with the ability to copy/paste, create
new directories, etc. This does not address the issue mentioned above where
using the global application shortcut does not apply to whatever view has
focus.
This patch exposes some fields about purgeable memory regions.
We now also show total purgeable volatile and non-volatile memory in
the big process table.
Using int was a mistake. This patch changes String, StringImpl,
StringView and StringBuilder to use size_t instead of int for lengths.
Obviously a lot of code needs to change as a result of this.
Ref: #826
Right-clicking a directory no longer has the "Open in TextEditor" entry.
Right-clicking the directory view now allows you to create a new directory.
Currently, when `set_text()` is called on GTextDocument a change is
triggered and all clients registered get a document_did_set_text
call. This in turn causes the TextEditorWidget to mark the document
as dirty even on the first open, which makes for a weird experience.
This is a tiny bar at the left of the taskbar where you can put
your most used apps to launch them with a single click. In a way,
it's another replacement for the Launcher, in addition to the app
menu. Unlike the launcher and the menu, it's not meant to be the
primary way to launch apps; it's only a faster way to launch a few
most often used utilities.
We now show a quick window outline animation when going in/out of
minimized state. It's a simple 10 frame animation at 60fps, just to
give a visual cue of what's happening with the window.
The Taskbar sends over the corresponding button rect for each window
to the WindowServer using a new WM_SetWindowTaskbarRect message.
Note that when unminimizing, we still *show* the window right away,
and don't hold off until the animation has finished. This avoids
making the desktop feel slow/sluggish. :^)
Fixes#825
The logic already existed. I just moved it to a separate lambda then added it
to the appropriate action. Note that when the tree view refreshes, it seems to
randomly open trees. I would like to fix this in a separate PR.
This patch introduces code generation for the WindowServer IPC with
its clients. The client/server endpoints are defined by the two .ipc
files in Servers/WindowServer/: WindowServer.ipc and WindowClient.ipc
It now becomes significantly easier to add features and capabilities
to WindowServer since you don't have to know nearly as much about all
the intricate paths that IPC messages take between LibGUI and WSWindow.
The new system also uses significantly less IPC bandwidth since we're
now doing packed serialization instead of passing fixed-sized structs
of ~600 bytes for each message.
Some repaint coalescing optimizations are lost in this conversion and
we'll need to look at how to implement those in the new world.
The old CoreIPC::Client::Connection and CoreIPC::Server::Connection
classes are removed by this patch and replaced by use of ConnectionNG,
which will be renamed eventually.
Goodbye, old WindowServer IPC. You served us well :^)
This patch adds these I/O counters to each thread:
- (Inode) file read bytes
- (Inode) file write bytes
- Unix socket read bytes
- Unix socket write bytes
- IPv4 socket read bytes
- IPv4 socket write bytes
These are then exposed in /proc/all and seen in SystemMonitor.
Previously it was not possible to see what each thread in a process was
up to, or how much CPU it was consuming. This patch fixes that.
SystemMonitor and "top" now show threads instead of just processes.
"ps" is gonna need some more fixing, but it at least builds for now.
Fixes#66.
This opens the source of the current document in TextEditor.
For file:// URLs, we open the local file, but for all other protocols,
a temporary file is generated, containing the document source.
Longer-term we should build some kind of viewer into the Browser app
instead. That would avoid silly problems like how this forgets to
delete the temporary files, for instance :^)
Instead of implicitly copying whatever you select, and pasting when you
middle-click, let's have traditional copy and paste actions bound to
Ctrl+Shift+C and Ctrl+Shift+V respectively.
This patch adds pthread_create() and pthread_exit(), which currently
simply wrap our existing create_thread() and exit_thread() syscalls.
LibThread is also ported to using LibPthread.
The Launcher's functionality has been replaced by the app shortcuts in
the system menu.
There were various window management hacks to ensure that the launcher
stayed below all other windows while also being movable, etc.
This simple helper escapes '<', '>' and '&' so they can be used in HTML
text without interfering with the parser.
Use this in IRCClient to prevent incoming messages from messing with
the DOM :^)
Renamed "Position" to "Elapsed". "channel/channels" automatically
changes now when more than one channel exist. The current file name
is now displayed in the window title.
This seemed like a perfect fit for LibHTML. We can now style the IRC
channels and queries however we like with the power of HTML and CSS.
This patch doesn't do much in the way of styling, it just gets the
basic mechanism into place.
When attempting to open a file that doesnt exist or has permission
problems, the application would end after hitting OK on the message
box instead of starting up to an empty editor.
I believe this has something to do with the dialog event loop
interfering with the application event loop, or possibly the fact
that the window creation code is in the show() method.
To work around this I now call the open_file() method after the
show() method.
Instead of quitting the application immediately when the pty gives an
EOF, fire an on_command_exit hook so the TerminalWidget client can
decide for himself what to do.
Instead, have TerminalWidget provide an on_title_change hook.
This allows embedders to decide for themselves what to do if we receive
a "set terminal title" escape sequence.
When embedding a TerminalWidget, you might not want it to automatically
update its own size policy based on the exact terminal buffer size.
This behavior is now passed as a flag to the TerminalWidget constructor
which makes it behave nicely both inside HackStudio and in Terminal.
If you had made a change to the first 4 bits of a byte and then changed
your offset via keyboard or menu option it would change the last 4 bits
of the new offset the next time you made a change and would not show that
the byte had been changed at the new offset.
This patch implements basic support for <a href="#foo"> fragment links.
To figure out where we actually want to scroll to, we have to do
something different based on the layout node's box type. So if it's a
regular LayoutBox we can just use the LayoutBox::position().
However, if it's an inline layout node, we use the position of the
first line box fragment in the containing block contributed by this
layout node or one of its descendants.
HtmlView will now invoke the on_link_hover hook when the cursor enters
or leaves a DOM node that has an enclosing link element.
This patch also updates the meaning of Node::enclosing_link_element()
to find the nearest HTMLAnchorElementAncestor *with an href attribute*.
Minor patch, but I was watching one of your videos on YouTube and
thought that the pop-up was unecessary/annoying in this case. Love
your enthusiasm for the project :^)
The layout root is now kept alive via Document::m_layout_root.
This will allow us to do more layout-related things inside the inner
layer of LibHTML without reaching out to the HtmlView.
I'd like to keep HtmlView at a slightly higher level, to prevent it
from getting too complex.
This patch also fixes accidental disconnection of the layout tree from
the DOM after doing a layout tree rebuild. ~LayoutNode() now only
unsets the DOM node's layout_node() if it's itself.
For now this is simply a counter+hook exposed by ResourceLoader and
shown in the Browser status bar.
This is not very nuanced, and it would be nice to expose more info so
we could eventually do something like a progress bar.
Node.normalize() is a standard DOM API that coalesces Text nodes.
To avoid clashing with that, rename it to fixup().
This patch also makes it happen automagically as part of parsing.
Instead of HtmlView clients having to worry about parsing and loading
the default CSS, just take care of it inside StyleResolver.
The default style is automatically inserted into the stylesheet list,
at the very start, so everyone else gets a chance to override it.
We now use GLazyWidget for all the secondary tabs, which makes the
program start up way faster than before.
There's a noticeable delay when you click on the "PCI Devices" tab
for the first time, but that's definitely better than always eating
that delay before seeing a window at all. :^)
If we resize/maximize the window, we might end up with some lines in
history that had a different length than the current terminal width.
That's okay, so let's not crash because of it.
Fixes#620.
This patch adds three separate per-process fault counters:
- Inode faults
An inode fault happens when we've memory-mapped a file from disk
and we end up having to load 1 page (4KB) of the file into memory.
- Zero faults
Memory returned by mmap() is lazily zeroed out. Every time we have
to zero out 1 page, we count a zero fault.
- CoW faults
VM objects can be shared by multiple mappings that make their own
unique copy iff they want to modify it. The typical reason here is
memory shared between a parent and child process.
GFilePicker
- Fixed GFilePicker to use new ref-counted construct method to stop crashing on open dialog.
- PaintBrush is still crashing on open dialog due to an unrelated issue.
PaintBrush
- Created 16x16 icon for PaintBrush
- Moved Open option into App menu.
- Changed help menu to make use of the standardized About dialog.
GEventLoop was just a dummy subclass of CEventLoop anyway. The only
thing it actually did was make sure a GWindowServerConnectionw was
instantiated. We now take care of that in GApplication instead.
CEventLoop is now non-virtual and a little less confusing. :^)
Okay, I've spent a whole day on this now, and it finally kinda works!
With this patch, CObject and all of its derived classes are reference
counted instead of tree-owned.
The previous, Qt-like model was nice and familiar, but ultimately also
outdated and difficult to reason about.
CObject-derived types should now be stored in RefPtr/NonnullRefPtr and
each class can be constructed using the forwarding construct() helper:
auto widget = GWidget::construct(parent_widget);
Note that construct() simply forwards all arguments to an existing
constructor. It is inserted into each class by the C_OBJECT macro,
see CObject.h to understand how that works.
CObject::delete_later() disappears in this patch, as there is no longer
a single logical owner of a CObject.
Subclasses of CNetworkJob handle this by overriding shutdown().
This patch implements it for CHttpJob by simply tearing down the
underlying socket.
We also automatically call shutdown() after the job finishes,
regardless of success or failure. :^)
The C_OBJECT macro now also inserts a static construct(...) helper into
the class. Now we can make the constructor(s) private and instead call:
auto socket = CTCPSocket::construct(arguments);
construct() returns an ObjectPtr<T>, which we'll later switch to being
a NonnullRefPtr<T>, once everything else in in place for ref-counting.
The delete action now actually deletes files (after asking the user for
confirmation, of course.) Deleting directories is not yet supported.
Fixes#541.
Fix a crash when opening a folder, and another one when trying to open
a newly created folder.
It was not safe to modify a GModelSelection while it's being iterated over.
Fixes#536.
When the user has scrolled up and begins typing, the scrollbar will
automatically return them to the current cursor position so that they
can see what they're typing.
The program will now automatically select the user's currently
chosen resolution when it is loaded up, however it is not
"visually selected" in the `GListView`
Moved the `resolution_list` list to be on the top to keep it consistent
with the wallpaper tab.
As was mentioned in #556, the `DisplayProperties` Wallpaper tab
contained a lot of "extra space", in which half the tab was taken up
by the list of wallpapers. The rest of that space is now reserved for
a wallpaper preview, so the user can see the selected image before
applying it.
When copying a list of files to the clipboard, we now use the special
data type "file-list".
This allows us to have the paste action's enabled state reflect the
actual ability to paste something. :^)
Based on whether something is selected or not. I added a FIXME about
the paste action, since that will require some more coordination with
the system clipboard.
An interactive application to modify the current display settings, such as
the current wallpaper as well as the screen resolution. Currently we're
adding the resolutions ourselves, because there's currently no way to
detect was resolutions the current display adapter supports (or at least
I can't see one... Maybe VBE does and I'm stupid). It even comes with
a very nice template'd `ItemList` that can support a vector of any type,
which makes life much simpler.
This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)
This is not as perfect as it is elsewhere in the system, as we cannot
really change how terminal "thinks about" characters and bytes. What
we can do though, and what this commit does, is to *render* emojis, but
make it seem as if they take up all the space, and all the columns their
bytes would take if they were all regular characters.
This can play anything that AWavLoader can load (so obviously only WAV
files at the moment.)
It works by having a timer that wakes up every 100ms and tries to send
a sample buffer to the AudioServer. If our server-side queue is full
then we wait until the next timer iteration and try again.
We display the most recently enqueued sample buffer in a nice little
widget that just plots the samples in green-on-black. :^)
CTCP requests are client-to-client messages that are sent as either
PRIVMSG (for requests) or NOTICE (for responses) and wrapped in ASCII
character 0x01 on both sides.
This patch implements responding to the very common VERSION and PING
requests. We always get a VERSION request from freenode when connecting
there, for instance. :^)
It's a little unfortunate that we have two separate code paths that can
lead to asking the user about this. Longer-term we should find a way to
unify these things.
Fixes#491.
This library is meant to provide C++-style wrappers over lower
level APIs such as syscalls and pthread_* functions, as well as
utilities for easily running pieces of logic on different
threads.
We were checking the columns of the whole selection instead of the
the specfic line were modifying. Because of this, the selection
remained if the selection's column on another line was less than
the cursor.
