IFF was a generic container fileformat that was popular on the Amiga
since it was the only file format supported by Deluxe Paint.
ILBM is an image format popular in the late eighties/nineties
that uses the IFF container.
This is a very first version of the decoder that only supports
(byterun) compressed files with bpp <= 8.
Only the minimal chunks are decoded: CMAP, BODY, BMHD.
I am planning to add support for the following variants:
- EHB (32 colours + lighter 32 colours)
- HAM6 / HAM8 (special mode that allowed to display the whole Amiga
4096 colours / 262 144 colours palette)
- TrueColor (24bit)
Things that could be fun to do:
- Still images could be animated using color cycle information
The error.html page now uses the resource_directory_url this
variable contains the relative path to /Base/res/ on the host
system as a file:// url. This is needed for future pages to load
resource files like icons. For the error.html page this was not
really needed because it lies over this own URL in FrameLoader.cpp.
Using the kernel stack is preferable, especially when the examined
strings should be limited to a reasonable length.
This is a small improvement, because if we don't actually move these
strings then we don't need to own heap allocations for them during the
syscall handler function scope.
In addition to that, some kernel strings are known to be limited, like
the hostname string, for these strings we also can use FixedStringBuffer
to store and copy to and from these buffers, without using any heap
allocations at all.
The user can now save, load, and view calendars. A calendar is made up
of an array of events which are saved in a JSON file. In the future we
should implement the iCalendar standard instead of using a custom
format.
This changes the default behavior, so that, by default, color codes,
hyperlinks and additional spacing are only emitted when standard
output is connected to a terminal.
The default coloring behavior can be overridden with the `--color`
option. Valid arguments for this option are: 'always', 'never' and
'auto' (default).
This is only possible if listing an entire directory, because the LibC
readdir function will return the raw inode number in each struct dirent,
therefore allowing to print it as well.
Add the CanvasTextDrawingStyles mixin with the textAlign and
textBaseline attributes. Update fill_text in CanvasRenderingContext2D
to move the text rect by the text align and text baseline attributes.
Wrote a simple HTML example to showcase the new features.
...along with `outline-color`, `outline-style`, and `outline-width`.
This re-uses the existing border-painting code, which seems to work well
enough!
This replaces the previous code for drawing focus-outlines, with generic
outline painting for any elements that want it. Focus outlines are now
instead supported by this code in Default.css:
```css
:focus-visible {
outline: auto;
}
```
When joined border width is zero width, then the midpoint
of the joined corner is no longer need to be computed
anymore. Just set the mid point to be the endpoint of the
corner.
This option allows the user to change which colums are displayed
by giving comma or space separated list of column format specifiers.
A column format specifier is of the form: `COLUMN_NAME[=COLUMN_TITLE]`.
Where `COLUMN_NAME` is any of: uid, pid, ppid, pgid, sid, state, tty,
or cmd. Specifying a `COLUMN_TITLE` will change the name shown in the
column header.
`COLUMN_TITLE` may be blank. If all given column titles
are blank, the header is omitted.
The refactor of the border painting mainly to handle:
1. Single border with minor border radius.
2. Different border widths and border colors joined situations.
This refactor only apply to solid border.
The main differece is to use Path.fill to paint each border,
not fill_rect anymore. There's a special case need to consider.
The Path.fill will leave shared edge blank between two borders.
To handle this, we decide to combine the borders with same color
to paint together.
When specifying either `background-position-x: right` or
`background-position-y: bottom` without an offset value no
EdgeStyleValue was created.
However, the spec says the offset should be optional.
Now, if you do not provide an offset, it creates the EdgeStyleValue
with a default offset of 0 pixels.
Previously, it was assumed that only one filtering option, such as
`-u` or `-p` would be used at a time. With this PR, processes are now
shown if they match any of the specified filters.
Describe how to use the two new context and unified format options in
the diff utility. Also change the example comparison of two files so
they contain more lines as that is much more interesting (and useful).
This small utility is something we probably needed for a very long
time - a way to print memory statistics in an elegant manner.
This utility opens /sys/kernel/memstat, reads it and decode the values
into human readable entries, possibly even into human-readable sizes.
Use LibCore ArgsParser to parse the parameters instead of using the raw
strings from the argv (Main::Arguments) array.
Also, use indicative names for variables in the code so the utility code
is more understandable.
I could not find a vector graphic of Buggie, so I've now made one
and am adding it exclusively as a .tvg :^)
Should be easy to convert to an SVG too :)
This man page was referenced from some places. This is mostly a
condensed version of the POSIX behavior that the system call
implementation already has, only documenting the obviously visible
errors (in source code) we do actually report.
This is a preparation before we can create a usable mechanism to use
filesystem-specific mount flags.
To keep some compatibility with userland code, LibC and LibCore mount
functions are kept being usable, but now instead of doing an "atomic"
syscall, they do multiple syscalls to perform the complete procedure of
mounting a filesystem.
The FileBackedFileSystem IntrusiveList in the VFS code is now changed to
be protected by a Mutex, because when we mount a new filesystem, we need
to check if a filesystem is already created for a given source_fd so we
do a scan for that OpenFileDescription in that list. If we fail to find
an already-created filesystem we create a new one and register it in the
list if we successfully mounted it. We use a Mutex because we might need
to initiate disk access during the filesystem creation, which will take
other mutexes in other parts of the kernel, therefore making it not
possible to take a spinlock while doing this.
This change was a long time in the making ever since we obtained sample
rate awareness in the system. Now, each client has its own sample rate,
accessible via new IPC APIs, and the device sample rate is only
accessible via the management interface. AudioServer takes care of
resampling client streams into the device sample rate. Therefore, the
main improvement introduced with this commit is full responsiveness to
sample rate changes; all open audio programs will continue to play at
correct speed with the audio resampled to the new device rate.
The immediate benefits are manifold:
- Gets rid of the legacy hardware sample rate IPC message in the
non-managing client
- Removes duplicate resampling and sample index rescaling code
everywhere
- Avoids potential sample index scaling bugs in SoundPlayer (which have
happened many times before) and fixes a sample index scaling bug in
aplay
- Removes several FIXMEs
- Reduces amount of sample copying in all applications (especially
Piano, where this is critical), improving performance
- Reduces number of resampling users, making future API changes (which
will need to happen for correct resampling to be implemented) easier
I also threw in a simple race condition fix for Piano's audio player
loop.
Previously, the `-p` option printed the path of the file being
processed before any strings for that file. The `-f` prints the file
path before each string . This matches the behavior of strings on
Linux and FreeBSD.
This is a sensible separation of concerns that mirrors the WindowServer
IPC split. On the one hand, there is the "normal" audio interface, used
for clients that play audio, which is the primary service of
AudioServer. On the other hand, there is the management interface,
which, like the WindowManager endpoint, provides higher-level control
over clients and the server itself.
The reasoning for this split are manifold, as mentioned we are mirroring
the WindowServer split. Another indication to the sensibility of the
split is that no single audio client used the APIs of both interfaces.
Also, useless audio queues are no longer created for managing clients
(since those don't even exist, just like there's no window backing
bitmap for window managing clients), eliminating any bugs that may occur
there as they have in the past.
Implementation-wise, we just move all the APIs and implementations from
the old AudioServer into the AudioManagerServer (and respective clients,
of course). There is one point of duplication, namely the hardware
sample rate. This will be fixed in combination with per-client sample
rate, eliminating client-side resampling and the related update bugs.
For now, we keep one legacy API to simplify the transition.
The new AudioManagerServer also gains a hardware sample rate change
callback to have exact symmetry on the main server parameters (getter,
setter, and callback).
If more than one file is specified on the command line and the `-L`
option is used, the totals field will show the longest line
encountered; it is not a sum like the other values.
The intention for this utility is to eventually become a general-purpose
multimedia conversion tool like ffmpeg (except probably not with as many
supported formats, stream mappings and filters). For now, we can not
write any video format so the added complexity is not necessary at the
moment.
Works for fills and strokes (using colors, gradients, or patterns),
along with images.
fill_rect() has been updated to use fill_path(), which allows it to
easily transform the rect, and already supports opacity.

The translation to the bounding box location is handled by the gradient
transform, also doing it here breaks things.
This fixes the MDN <radialGradient> example.
It's a png file, not a jpeg file, so give it the correct name.
If I read WindowFrame.cpp right, the hover bitmap only works if
the file is named .png, too.
(Noticed by running `find Base/res/icons -name '*.jpg'`.)
Update the Assistant manpage with instructions on how to run a command
in Terminal. Reflect this to the Assistant section in Tips-and-Tricks.
Also add instructions for launching applications with arguments.
The creator of this site is most definitely not going to enforce his
copyright, yes, but it's still a bad idea to keep around an unlicensed
copy of someone else's work. We no longer use it to 'test' anything, so
let's just remove it entirely.
bmpsuite on GitHub is licensed under the GPLv3:
https://github.com/jsummers/bmpsuite/blob/master/COPYING.txt
However, we did not "conspicuously and appropriately publish on each
copy an appropriate copyright notice", therefore we probably were in
violation with GPLv3 paragraph 4, "Conveying Verbatim Copies".
Let's just remove this entirely, because Ladybird can just access
the original pages instead.
At the time of writing, `bmpsuite.html` and the HTML response from the
linked URL are byte-identical.
This ensures that the RAM does not fill up with already processed
coredumps when many tests crash (as is the case on AArch64). We only
do this in self-test mode so as to avoid racing CrashDaemon.
This partially implements CSS-Animations-1 (though there are references
to CSS-Animations-2).
Current limitations:
- Multi-selector keyframes are not supported.
- Most animation properties are ignored.
- Timing functions are not applied.
- Non-absolute values are not interpolated unless the target is also of
the same non-absolute type (e.g. 10% -> 25%, but not 10% -> 20px).
- The JavaScript interface is left as an exercise for the next poor soul
looking at this code.
With those said, this commit implements:
- Interpolation for most common types
- Proper keyframe resolution (including the synthetic from-keyframe
containing the initial state)
- Properly driven animations, and proper style invalidation

Corrects a slew of titles, buttons, labels, menu items and status bars
for capitalization, ellipses and punctuation.
Rewords a few actions and dialogs to use uniform language and
punctuation.
These 2 are an actual separate types of syscalls, so let's stop using
special flags for bind mounting or re-mounting and instead let userspace
calling directly for this kind of actions.
Several differences here:
- Passing `-q` multiple times will add them together, instead of the
last one overwriting the previous ones.
- `-q` PIDs can be separated by commas as well as spaces.
- We check that the PIDs are integers while parsing the arguments,
instead of later on.
The "parse a list of things as an option" is extracted into a helper
function, because we're going to want the same logic for `-g`, `-G`,
`-p`, `-t`, `-u`, and `-U`.
Since LibFSAC requires a reified window before loading a font, it
makes sense to have a safe null state for the app.
This lets us stay alive after a failed file request on startup,
handle failure at any point during initialization, and claw back
memory from all our font RefPtrs.
A default startup font or none at all can now be set in FontEditor.ini
This allows it to read/write to the user's clipboard properly. Prior to
this, it would be writing to the Clipboard server running under the
window user, which doesn't impact other users (like anon).

Csilla Regular 12 is used for inline code in LibMarkdown. It was
missing basic arrows and ellipsis needed by man pages referencing menu
items. I have added these and some extras.

Where an arrow is indicated by -> turn it into an actual arrow →
(U+2192 Rightwards Arrow). This looks much neater.
Inspired by Notion doing this automatically when you type "->".
I've made various corrections: fixing grammatical errors, removing
unnecessary or adding-in missing spaces. Made the style of references
to menu items more consistent. Generally I've tried to make the pages
read better. Terminal has had more adjustment than the others as its
Settings were recently changed and the man page now reflects this.
This adds information about the user owning the process to our netstat
output. We do not fully match the behaviour of Linux as we don't show
an inode information.
I've been unsatisfied with the current Assistant app icon (16px).
After trying many variations, I have ended-up with this. The changes
may be slight, but the bow tie now has a more natural shape including
a more prominent knot, bringing it more inline with the 32px version.
Plus the shading has been tweaked.
In Snake, the menu for choosing a skin looked messy due to
inconsistent capitalization. Two skins names were entirely lowercase.
For the sprite-based skins, the menu takes the name of each skin's
directory, so I have capitalized these.
Capitalizing the original snake skin required more change than simply
renaming a directory.
The pattern to construct `Application` was to use the `try_create`
method from the `C_OBJECT` macro. While being safe from an OOM
perspective, this method doesn't propagate errors from the constructor.
This patch make `Application` use the `C_OBJECT_ABSTRACT` and manually
define a `create` method that can bubble up errors from the
construction stage.
This commit also removes the ability to use `argc` and `argv` to
create an `Application`, only `Main`'s `Arguments` can be used.
From a user point of view, the patch renames `try_create` => `create`,
hence the huge number of modified files.
The graphics directory is a more suitable home for game assets.
Also, move card backs into their own subfolder in preparation for a
themes subfolder for card fronts.
These were part of the postcreate script previously, but with the new
powers of sed, we can text-replace the library name and make changing
them much more convenient.
Namely, the window title and size are carried over, since a larger
window with a more readable "Example Application" title is better to
understand. I also took the opportunity to add a missing trailing
newline to the generated CMake file.
This program has never lived up to its original idea, and has been
broken for years (property editing, etc). It's also unmaintained and
off-by-default since forever.
At this point, Inspector is more of a maintenance burden than a feature,
so this commit removes it from the system, along with the mechanism in
Core::EventLoop that enables it.
If we decide we want the feature again in the future, it can be
reimplemented better. :^)
Without `-y`, to show the current full year you'd have to specify which
one: `cal 2023`. Adding `-y` makes it possible to see the full current
year without remembering what year we are in.
This option is also stolen from FreeBSD :^)
Additionally, validate args: prevent passing both -3 and -y at the
same time. Passing both `--three-month-mode` and `--year` to `cal`
doesn't make sense. You'd either want the one or the other.
Making it configurable in system settings :^)
The --start-day option can still overwrite this global default.
This change makes it no longer possible to use unveil: as we have
to load the Calendar config file, which might be in a dynamic location.
It's also neccessary to add `cpath` to the pledge, as opening a
nonexistent config file with Core::ConfigFile::open_for_app creates it.
Making all the other parts of the world happier :^)
Add a `--starting-day` (`-s`) option to be compatible with GNU cal,
which has a similar option. The GNU option takes allows passing either
an int or a day name. Let's do something similar using weekdays we
already have in AK/DateConstants.h.
Also add myself to the copyright header, as by now I've modified most of
the lines in this file.
...instead of putting a star `*` next to it. This makes `cal`s output
much prettier, and gets rid of one FIXME. :^)
Don't use the escape sequence from the deleted FIXME - \e[30;47m would
set the background to white and foreground to black - which presumably
wouldn't do much on a light-theme terminal. Instead use \e[7m which sets
the color as "inverted".
Every other cal implementation just highlights the current day instead
of letting you specify a custom one to highlight. It doesn't seem to be
that useful, and is currently broken - no day gets highlighted at all,
because the `target_day` global is never written to.
Moreover, this complicates parsing the arguments. This commit also fixes
parsing a case where just a year is provided to `cal` - for example `cal
2023`.
This is quite useful for userspace applications that can't cope with the
restriction, but it's still useful to impose other non-configurable
restrictions by using jails.
Previously, `Heap` would store serialized data in blocks of 1024 bytes
regardless of the actual length. Data longer than 1024 bytes was
silently truncated causing database corruption.
This changes the heap storage to prefix every block with two new fields:
the total data size in bytes, and the next block to retrieve if the data
is longer than what can be stored inside a single block. By chaining
blocks together, we can store arbitrary amounts of data without needing
to change anything of the logic in the rest of LibSQL.
As part of these changes, the "free list" is also removed from the heap
awaiting an actual implementation: it was never used.
Note that this bumps the database version from 3 to 4, and as such
invalidates (deletes) any database opened with LibSQL that is not
version 4.
This is to allow testing autoplay, poster images, etc. without having to
stash local changes to the page. This also changes the URLs used on the
page to be relative to the page itself, to allow the page to load both
on Serenity and Lagom.
This adds a checkbox to enable autoplay on all websites (disabled by
default) and a website list to enable autoplay on individual websites
(set to file:// URLs only by default).
VALUES-4 defines the internal representation of `calc()` as a tree of
calculation nodes. ( https://www.w3.org/TR/css-values-4/#calc-internal )
VALUES-3 lacked any definition here, so we had our own ad-hoc
implementation based around the spec grammar. This commit replaces that
with CalculationNodes representing each possible node in the tree.
There are no intended functional changes, though we do now support
nested calc() which previously did not work. For example:
`width: calc( 42 * calc(3 + 7) );`
I have added an example of this to our test page.
A couple of the layout tests that used `calc()` now return values that
are 0.5px different from before. There's no visual difference, so I
have updated the tests to use the new results.
Add a list of system and general keyboard shortcuts as well as a list
of tips and tricks to man7 (Miscellanea). Add links to these in the
Help-index to aid discoverability for new users.
Prior to this commit, when you double-click a .zip file to open it, it
gets opened in Text-Editor as there is no other file association.
Now, when FileManager is invoked with a .zip file as the first argument,
a temporary directory will be created and the .zip will be extracted
into it. Once the FileManager window is closed, Core::TempFile will
delete the temporary directory.
This adds something like what we see in other operating systems' file
explorers, except for the fact that most other operating systems will
treat the .zip file as its own independent read-only filesystem. It
would be nice to do that in the future, but I feel like this is
sufficient for now.
by making them `monospace` in the Help page, and bold in the manual.
This helps to quickly find out where the keyboard controls are in the
manual when skimming its contents.
The LUN.target_id parameter points to a NVMe Namespace which starts from
1 and not 0. Fix the document to reflect the same while addressing a
nvme device in the boot parameters
This fixes a bug in the CSS Grid when there is a column and/or row gap,
as previously it would take the index of the incorrect column when
finding the `AvailableSize`.
There is a mild complication in the GridFormattingContext as the
OccupationGrid does not take into account the gap columns and rows that
later appear in the `Vector<TemporaryTrack>` columns and rows. The
PositionedBoxes are kind of a connection between the two, and so it's
now more explicit whether you would like to refer to a column by its
position taking into the gap columns/rows or not.
