The C++ language-server can now autocomplete include paths.
Paths that start with '<' will be searched in /usr/include, and paths
that start with '"' will be searched in the project's root directory.
autocomplete_property => try_autocomplete_property
autocomplete_name => try_autocomplete_name
This makes it more clear that these variants may fail because e.g
the node is not a property / not a name.
With very small bitmaps and small scale factor, such as tile.png, the
type conversion in the call to Bitmap:create would cause width or
height to be 0.
Fixes#7352
Instead of picking the card with the lowest value we should pick the
card with the highest value for which we know no lower value card is
in play anymore and that someone else still has an even higher value
card.
Problem:
- Default destructors (and constructors) are in `.cpp` files. This
prevents the compiler's optimizer from inlining them when it thinks
inlining is appropriate (unless LTO is used).
- Forward declarations can prevent some optimizations, such as
inlining of constructors and destructors.
Solution:
- Remove them or set them to `= default` and let the compiler handle
the generation of them.
- Remove unneeded forward declarations.
This patch updates the Page::keydown_event event handler to implement
crude Unicode support. It implements new method in EditEventHandler to
more easily handle deleting a single character after the cursor.
Furthermore, it makes use of the previously implemented methods to
increment and decrement the cursor position, which take into account
that Unicode codepoint may be multiple bytes wide.
This means it is now possible to mostly edit Unicode in editable DOM
nodes without any crashes. :^)
This introduces methods to increment and decrement the cursor position.
This is non-trivial as the cursor position is specified in bytes rather
than codepoints. Thus, it sometimes needs to be incremented or
decremented by more than one, depending on the codepoint to "jump over".
Because the cursor blink cycle needs to be reset after moving the
cursor, methods calling the ones in DOM::Position are implemented in
Frame. Furthermore, this allows the cursor_position() getter to stay
const. :^)
Additionally, it adds a offset_is_at_end_of_node() method which checks
if the current offset points to the end of the node.
This patch makes two modifications to improve the behavior of cursors in
editable DOM nodes, such as HTML tags with the contenteditable
attribute.
When the cursor blink cycle is reset in an editable DOM node, a repaint
should be initiated. For this, set_needs_display() needs to be called on
the layout node. Previously, the cursor blink cycle would not reset
properly and moving the cursor with the arrow keys did not feel
intuitive.
Furthermore, this modifies one of the conditions necessary to actually
paint the cursor, which previously prevented it from being painted when
at the end of a text node, after all the text present.
Before this patch, pressing modifier keys such as Ctrl would insert
whitespace into editable DOM nodes. This patch crudely fixes that
behavior by checking if the codepoint associated with the event is
non-zero.
This patch downgrades some TODO() calls when the cursor in an editable
DOM node should move to the previous or next node. Previously, the
process would crash, whereas now, the cursor will just stay where it
was.
This seems more sensible for now, as there is no reason to crash just
because of this.
Follow-on to #7337. Been seeing other CI test failures that point to
these temp directories, so let's just move all of them to /tmp. I'm sure
someone will write ext2fs stress tests later :^)
Example:
/usr/Tests/Shell/control-structure-as-command.sh
Core::Socket: Failed to connect() to /tmp/portal/inspectables: ...
+ rm -rf shell-test 2>/dev/null
+ mkdir shell-test
Error: The action has timed out.
By doing the offset calculation in {get,put}_by_index() we would
delegate these operations to Object for any index >= (array length -
byte offset). By doing the offset calculation in data() instead, we can
just use the unaltered property index for indexing the returned Span.
In other words: data()[0] now returns the same value as indexing the
TypedArray at index 0 in JS.
This also fixes a bug in the js REPL which would not consider the byte
offset and subsequently access the underlying ArrayBuffer data with a
wrong index.
If we don't have any bytes to print in hex representation, just return
early instead of printing a newline in preparation for the data that
won't follow. :^)
Changes to the system font settings are now persisted in /etc.
Note that you still need to restart the system for changes to fully
apply in all programs.
This patch adds a set_system_fonts() IPC API that takes the two main
font queries as parameters. We'll probably expand this with additional
queries when we figure out what they should be.
Note that changing the system fonts on a live system mostly takes
effect in newly launched programs. This is because GUI::Widget will
currently cache a pointer to the Gfx::FontDatabase::default_font()
when first constructed. This is something we'll have to fix somehow.
Also note that the settings are not yet persisted.
Instead of everybody getting their system fonts from Gfx::FontDatabase
(where it's all hardcoded), they now get it from WindowServer.
These are then plumbed into the usual Gfx::FontDatabase places so that
the old default_font() and default_fixed_width_font() APIs keep working.
If we can't parse a property we previously a log-line was generated.
However it is in our best interest to simply ignore vendor-specific
properties (e.g -moz-something or -webkit-something) since they are not
part of the spec.
The vendor-specific-ness is determined by looking whether the property
starts with '-'.
If we want to support some vendor-specific stuff, this doesn't get in
the way since this check takes place after the parser determined that
the current property is invalid.
This cuts down the log-noise of the parser.
This changes (context) menus across the system to conform to titlecase
capitalization and to not underline the same character twice (for
accessing actions with Alt).
We were leaking the "view source" and "downloading file" windows for
some reason, presumably it was necessary when these were first added.
Since they are owned by the spawning browser window, there's no need
to leak them.
Problem:
- `typedef`s are read backwards making it confusing.
- `using` statements can be used in template aliases.
- `using` provides similarity to most other C++ syntax.
- C++ core guidelines say to prefer `using` over `typedef`:
https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rt-using
Solution:
- Switch these where appropriate.
Problem:
- `static` variables consume memory and sometimes are less
optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
every time the function is run.
Solution:
- If a global `static` variable is only used in a single function then
move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
`constexpr`.
skip() is supposed to end up keeping the previous iterator only one
index behind the current one, and restore_to() should actually do the
restore instead of just removing the now-useless source positions.
Fixes#7331.
Previously, the ip would not be propagated correctly, and we would
produce invalid jumps when more than one level of nesting was involved.
This makes loops work :P
This will simply "link" any given module instances and produce a list of
external values that can be used to instantiate a module.
Note that this is extremely basic and cannot resolve circular
dependencies, and depends on the instance order.
Managing the instantiated modules becomes a pain if they're on the
stack, since an instantiated module will eventually reference itself.
To make using this simpler, just avoid copying the instance.
This fixes a FIXME and will allow linking only select modules together,
instead of linking every instantiated module into a big mess of exported
entities :P
This only tests "can it be parsed", but the goal of this commit is to
provide a test framework that can be built upon :)
The conformance tests are downloaded, compiled* and installed only if
the INCLUDE_WASM_SPEC_TESTS cmake option is enabled.
(*) Since we do not yet have a wast parser, the compilation is delegated
to an external tool from binaryen, `wasm-as`, which is required for the
test suite download/install to succeed.
This *does* run the tests in CI, but it currently does not include the
spec conformance tests.
If a line was larger than 1024 bytes or the file ended without a
newline character, can_read_line would return false.
IODevice::can_read_line() now reads until a newline is found or
EOF is reached.
fixes#5907
When reading from stdin, grep discards the last character,
even if that character is not \n.
This commit changes grep to no longer discard the last character from
a line.
This unifies how 3DFileViewer handles the initial file when starting
the application and when opening files later on via the menu.
Errors are shown both for the initial load as well as when loading
files later on. An error during file load no longer clears the
existing model.
It also adds support for specifying the filename as a command-line
argument.
The opened file's name is shown in the titlebar.
The HTML and Markdown preview modes both use an OutOfProcessWebView to
render the preview pane, and we were instantiating this view from GML.
This caused us to always spawn a WebContent process alongside every
TextEditor instance.
Fix this by deferring the OOPWV construction until we actually need it.
This makes launching TextEditor on a text file quite a bit faster. :^)
Instead of doing a full IPC round-trip for the client and server to
greet each other upon connecting, the server now automatically sends
a "fast_greet" message when a client connects.
The client simply waits for that message to arrive before proceeding.
(Waiting is necessary since LibGUI relies on the palette information
included in the greeting.)
This makes a few modifications to the statusbar text generation:
* Use the canonical U+XXXX representation of unicode characters.
* For control characters, display their alias instead of whitespace.
* Substitute RTL codepoints with U+FFFD so the text paints correctly.
* Only show the glyph's dimensions if it actually exists in the font.
This fixes#7286.
This hack allows for Boxes that have a background to be painted and a
border to accurately paint their border-radii if needed.
For that the box in with the background is drawn is extended to the
bordered_rect. The border is later drawn over this regardless.
Previously when drawing a Box that had all three, background, border
and a border-radius, there could be some white between the filling and
the border.
The struct BorderRadiusData contains the four radii of the box.
In case the specified borders are too large for the dimensions of the
box, they get scaled down.
This adds a function to draw a circle specified by a center point (
relative to the given Rect) and a radius. The circle arc is only drawn
inside the specified Rect as to allow for circle arc segments.
Technically this was already possible using draw_elliptical_arc(), but
the algorithm is quite involved and lead to wonky arcs when trying to
draw circle arc segments.
This takes care of the 1, 2, 3 and 4 parameter shorthand of the border-
radius identifier.
There are more as well as the ominous '/' character but that is for
another time. The 2 and 3 parameter versions are weird enough already.
I don't think anybody uses anything other than the 1 or 4 parameter
version or even the elliptical stuff.
Some people apparently like to type in full absolute paths into the
filename box of GUI::FilePicker. So let's handle that as you'd expect
by using the full path as the selected path.
Previously, this code would create a bitmap with the size of the screen
resolution, draw the new wallpaper into it, and then scale it down for
display inside the MonitorWidget.
This was done on every paint event, which made the code quite slow and
allocation-happy.
Instead of this, we now scale down the new wallpaper to a miniature
of the same scale as the little MonitorWidget screen. The miniature is
then used for tiling, etc. The miniature is cached and reused across
paint events if nothing else changes.
An application that allows opening arbitrary files from the filesystem
needs to allow itself to access the filesystem, otherwise there's no
point in supporting the feature. :^)
And the "thread" pledge is needed for background thumbnail generation.
In cases with ambiguous captures involving pawns (where multiple pieces
could have made the capture), we were exporting invalid syntax for
the move:
`1. e4 e5 2. Bb5 c6 3. Bxc6 ddxc6`
Move 3 should be `Bxc6 dxc6`, but we were duplicating the d on the pawn
move.
This makes un-styled text readable when using a dark system theme,
previously such text would be black, regardless of the theme background
color.
Fixes#7274.
For each .cpp file in the test suite data, there is a .ast file that
represents the "known good" baseline of the parser result.
Each .cpp file goes through the parser, and the result of
invoking `ASTNode::dump()` on the root node is compared to the
baseline to find regressions.
We also check that there were no parser errors when parsing the .cpp
files.
Previously, ASTNode::dump() used outln() for output, which meant it
always wrote its output to stdout.
After this commit, ASTNode::dump() receives an 'output' argument (which
is stdout by default). This enables writing the output to somewhere
else.
This will be useful for testing the LibCpp Parser with the output of
ASTNode::dump.
This is similar to the LibJS test data that resides in
/home/anon/js-tests.
It's more convenient than storing the test programs as raw strings
in the code.
The context menu for CatDog was shown when right clicking anywhere on
the screen because of global cursor tracking being enabled.
Also fix event not being passed by reference.
Fixes#7285
Hook the kernel page fault handler and capture page fault events when
the fault has a current thread attached in TLS. We capture the eip and
ebp so we can unwind the stack and locate which pieces of code are
generating the most page faults.

Hiding those frames doesn't really make sense. They're a major
contributor to a process' spent CPU time and show up in a lot of
profiles. That however is because those processes really do spend
quite a bit of time in the scheduler by doing lots of context
switches, like WindowServer when responding to IPC calls.
Instead of hiding these for aesthetic reasons we should instead
improve the scheduler.
It is too complex because it supports many options that are not
used by the search engine. It just makes format validation more
complicated.
Additionaly, now it's possible to have { } characters in search
engine URL (although they are not valid URL characters) :)
Previously <AK/Function.h> also included <AK/OwnPtr.h>. That's about to
change though. This patch fixes a few build problems that will occur
when that change happens.
Instead of sprinkling the definition of the ciper suites all over the
TLS implementation, let's regroup it all once and for all in a single
place, and then add our new implementations there.
Previously lsof would crash by incorrectly parsing valid file names
that contain spaces.
For example, established TCP socket file descriptors would cause an
lsof crash:
socket:127.0.0.1:33985 / 127.0.0.1:8080 (connected)
This commit fixes the issue by not parsing for white spaces to set the
file name.
For compressed coredumps, CrashReporter's argv were in this order:
CrashReporter path --unlink
Core::ArgsParser doesn't like that at all and would immediately exit
from main(), causing the crash reporter to never display.
When reloading a page multiple times, it was also added multiple
times to the history. This commit prohibits an url to be added
twice in a row.
Fixes#7264

This patch implements the HTML specification's "encoding sniffing
algorithm", which is used when no encoding can be obtained from the
Content-Type header (either because it doesn't contain a charset=...)
value or the file has not been opened via HTTP (as with local files).
It also modifies the creator of the HTMLDocumentParser to use the new
HTMLDocumentParser::create_with_uncertain_encoding static method, which
runs the encoding sniffing algorithm before instantiating the parser.
This now allows us to load local HTML pages (or remote pages without a
charset specified in the 'Content-Type' header) with a non-UTF-8
encoding such as 'windows-1252'. This would previously crash the
browser. :^)
This modifies the Document class to use Optional<String> for the
encoding. If the encoding is unknown, the Optional will not have a
value. It also implements the has_encoding() and encoding_or_default()
instance methods, the latter of which will return "UTF-8" as a fallback
if no encoding is present.
The usage of Optional<String> instead of the null string is part of an
effort to explicitly indicate that a string could not have a value.
This also modifies the former callers of encoding() to use
encoding_or_default(). Furthermore, the encoding will now only be set if
it is actually known, rather than just guessed by earlier code.
This modifies the Resource class to use Optional<String> for the
encoding. If the encoding is unknown, the Optional will not have a
value (instead of using the null state of the String class). It also
implements a has_encoding() instance method and modifies the callers
of Resource::encoding() to use the new API.
This patch changes the encoding_from_content_type function to only
return an encoding if it actually finds one, and leave it up to the
caller to decided on a default to use.
It also modifies the caller to expect an Optional<String> (instead of
relying on the null state of the String class) as a return value and
separates the encoding and MIME type determination. This will be built
upon in a further commit.
This patch changes get_standardized_encoding to use an Optional<String>
return type instead of just returning the null string when unable to
match the provided encoding to one of the canonical encoding names.
This is part of an effort to move away from using null strings towards
explicitly using Optional<String> to indicate that the String may not
have a value.
Second batch of detectable formats, this time with verious offsets, as
enabled by the previous commit.
This adds tar, and the three signature variants for iso-9660 image
files.
Currently, it is possible for the player to drag an entire stack
of cards to the foundation stack, provided the top card of the stack
(i.e the "root" card) can be dropped onto the foundation stack.
This causes an invalid state where, e.g, red cards end up in a
black foundation stack, or vice versa.
It was very confusing for every Tab to have their own GUI::Menubar that
got dynamically swapped in/out when switching tabs.
This change moves us to a single menubar per window, and BrowserWindow
is the owner of its own menubar.
- Make the ball chill out a bit by reducing its x velocity by 1.
- Make the AI dumber. It now relaxes until the ball is coming towards it
and is in its half of the court.
Just because you're the player, doesn't mean you can cheat ;)
- Limit paddle speed when following mouse cursor.
- Unhide pointer -- can't grab it, can't see when it's about to leave
the window otherwise.
- Add last pointer y position indication for the player paddle.
- Prevent the paddle from following the mouse when Up or Down is being
held (avoid controls fighting).
Begin and end triggers for AI paddle to start moving prevent it from
continually jerking around the ball's position. It still moves in steps
of paddle.speed though, but overall experience is smoother.
Player 1's score used to be score's width offset to the right. Now it's
score_margin away from the divider line, same as player 2's.
Also factored out score margin and increased it from 2px to 5px just
to make it look a little nicer.
Also tweak its text in the settings window to be clearer on what this
check box is doing. Seemed a bit confusing that settings changes
required an extra action to persist.
Currently, each time you open the settings window in 2048, it displays
the default values rather than the current values. This is confusing, so
display the current values instead.
When holding ctrl and scrolling, the page will be zoomed in an out.
When zoomed in on a page, scrolling with move vertically up and down
the page (or horizontally if shift is being held).
In order to speed up zooming, zoomed bitmaps are cached per-page at
each distinct zoom level. This cache is cleared every 30 seconds to
prevent OOM problems.
This commit adds the Renderer class, which is responsible for rendering
a page into a Gfx::Bitmap. There are many improvements to make here,
but this is a great start!
