This is an upscaled (no interpolation) version of the 16x16 icon, which
looks pretty neat given the pixelated appearance of the "Fire" demo
application. :^)
This adds the ability to specify cursor attributes as part of their
file names, which allows us to remove hard coded values like the hot
spot from the code. The attributes can be specified between the last
two dots of the file name. Each attribute begins with a character,
followed by one or more digits that specify a uint value.
Supported attributes:
x: The x-coordinate of the cursor hotspot
y: The y-coordinate of the cursor hotspot
f: The number of animated frames horizontally in the image
t: The number of milliseconds per frame
For example, the filename wait.f14t100.png specifies that the image
contains 14 frames that should be cycled through at a rate of 100ms.
The hotspot is not specified, so it defaults to the center.
Instead of symlinks showing up with the "filetype-symlink" icon, we now
generate a new icon by taking the target file's icon and slapping a
small arrow emblem on top of it.
This looks rather nice. :^)
HackStudio no longer has dedicated project files, so let's get rid of
the *.hsp file concept. It'll eventually produce some files again,
but they won't be the same kind of "project" files.
This is definitely not fully-featured, but basically we now handle
the clear property by forcing the cleared box below the bottom-most
floated box on the relevant side.
This is a new "browse" permission that lets you open (and subsequently list
contents of) directories underneath the path, but not regular files or any other
types of files.
This moves file extension to icon mappings from compile time macros to an
INI config file (/etc/FileIconProvider.ini), so file icons can easily be
customized and extended :^)
I also switched the format from a static file extension (".foo") to
glob-like patterns ("*.foo", using StringUtils::matches()), which allows
us to assign icons to specific exactly matching file names, like many
IDEs do - e.g. "CMakeLists.txt" or ".prettierrc".
It's a thin userland wrapper around adjtime(2). It can be used
to view current pending time adjustments, and root can use it to
smoothly adjust the system time.
As far as I can tell, other systems don't have a userland utility
for this, but it seems useful. Useful enough that I'm adding it to
the lagom build so I can use it on my linux box too :)
Most systems (Linux, OpenBSD) adjust 0.5 ms per second, or 0.5 us per
1 ms tick. That is, the clock is sped up or slowed down by at most
0.05%. This means adjusting the clock by 1 s takes 2000 s, and the
clock an be adjusted by at most 1.8 s per hour.
FreeBSD adjusts 5 ms per second if the remaining time adjustment is
>= 1 s (0.5%) , else it adjusts by 0.5 ms as well. This allows adjusting
by (almost) 18 s per hour.
Since Serenity OS can lose more than 22 s per hour (#3429), this
picks an adjustment rate up to 1% for now. This allows us to
adjust up to 36s per hour, which should be sufficient to adjust
the clock fast enough to keep up with how much time the clock
currently loses. Once we have a fancier NTP implementation that can
adjust tick rate in addition to offset, we can think about reducing
this.
adjtime is a bit old-school and most current POSIX-y OSs instead
implement adjtimex/ntp_adjtime, but a) we have to start somewhere
b) ntp_adjtime() is a fairly gnarly API. OpenBSD's adjfreq looks
like it might provide similar functionality with a nicer API. But
before worrying about all this, it's probably a good idea to get
to a place where the kernel APIs are (barely) good enough so that
we can write an ntp service, and once we have that we should write
a way to automatically evaluate how well it keeps the time adjusted,
and only then should we add improvements ot the adjustment mechanism.
Now the functions can actually be demonstrated by small examples,
embedded right inside the documentation via:
spreadsheet://example/<page>#<example_name>
Also allows pages to link to each other via the same scheme:
spreadsheet://doc/<page>
This is implemented in Line::Editor meaning not only the Shell will
respect it, but also js, Debugger etc.
Possible values are "ignorespace", "ignoredups" and "ignoreboth", as
documented in Shell-vars(7), for now.
The default value for the anon user (set in .shellrc) is "ignoreboth".
The configuration key [DNS] Nameserver has been renamed to Nameservers
and accepts a comma-separated list of nameserver addresses, which will
be queried in the given order until a response has been received.
The new default value is still Cloudflare's 1.1.1.1 as well as their
secondary DNS server 1.0.0.1.
For themes with primarily light text colors and dark backgrounds the
current almost-white background/black text tooltips look a bit out of
place. I've changed them to what I believe are sensible colors but theme
authors are of course free to tweak further.
The main inspiration behind this was to have a correct ex CSS unit.
The mean line is based off what it shows in the CSS Values and Units
Level 4 specification, section 6.1.1.

The language server keeps track of the content of currently edited
files by receiving updates about edit actions.
Also, C++ autocompletion is no longer tied to HackStudio itself and
moved to be part of the language server.
After dispatching a "change" event due to the checked state being
modified, we may have been removed from the layout tree.
Make LayoutCheckBox protect itself to prevent this from crashing.
Also, add a little test page for checkboxes. :^)
DC and AC table IDs read in the scan header segment weren't validated
against the IDs of Huffman tables read in the DHT segment. This caused
an OOB read when a Huffman table was accessed using the ID read in the
scan header segment. Furthermore, the decoder now replaces the old DC
or AC table if a redefinition has been found prior to the scan header.
Fixes#3439.
This patchset adds the following to the manpage:
- Mention `if` expressions.
- Add section about subshells
- Mention that control structures can now be used as commands
- Update the grammar.
- Fix small header size mistake with "Example"'s being larger than their
containing sections.
To keep track of ongoing terminal sessions, we now have a sort-of
traditional /var/run/utmp file, like other Unix systems.
Unlike other Unix systems however, ours is of course JSON. :^)
The /bin/utmpupdate program is used to update the file, which is
not writable by regular user accounts. This helper program is
set-GID "utmp".
Adds a GIF test suite HTML page that contains a selection of test
GIF images and reference PNGs for each frame
Adds a link to the GIF test suite on welcome.html
