This app allows the user to easily adjust his mouse's acceleration
as well as the scrollwheel's global scroll length.
The mouse acceleration changes would not be noticeable in qemu as
by default serenity uses VMWareBackdoor when available which lets
the host handle mouse movement instead of the guest (Serenity),
so in order to test this on a none-baremetal pc the VMWareBackdoor
has to be disabled.
Such errors are raised when SyntaxError nodes are executed, and are also
used for internal control flow.
The 'break' and 'continue' commands are currently only allowed inside
for loops, and outside function bodies.
This also adds a 'loop' keyword for infinite loops.
This is a simple application that can read a coredump file and display
information regarding the crash, like the application's name and icon
and a backtrace. It will be launched by CrashDaemon whenever a new
coredump is available.
Also, it's mostly written in GML! :^)
Closes#400, but note that, unlike mentioned in that issue, this
implementation doesn't ignore applications that "have been started in
the terminal". That's just overcomplicating things, IMO. When my js(1)
REPL segfaults, I want to see a backtrace!
The DevFS along with DevPtsFS give a complete solution for populating
device nodes in /dev. The main purpose of DevFS is to eliminate the
need of device nodes generation when building the system.
Later on, DevFS will assist with exposing disk partition nodes.
Make the little arrows point towards the large icon instead of away
from it. This feels like an obviously better visual clue that they're
pointers *to* something.
Problem:
- C functions with no arguments require a single `void` in the argument list.
Solution:
- Put the `void` in the argument list of functions in C header files.
With everything now using GUI::FileIconProvider and therefore loading
icons embedded in the executable files, this information is now longer
being used.
We might have to think about this again if we want to allow .af files
with custom commands (e.g. shell scripts). Maybe those could get away
with just an "Icon" entry under "[App]", but currently there's only
"Executable" anyway.
Browser supports very few protocols (http, https, gemini, file) at the
moment, so there's no point in using it as a catch-all and default
protocol handler. I added an explicit association for gemini to
/bin/Browser instead.
This stops Desktop::Launcher::open() from reporting success for any URL,
which really isn't the case (Browser shows an error page...).
Problem:
- `(void)` simply casts the expression to void. This is understood to
indicate that it is ignored, but this is really a compiler trick to
get the compiler to not generate a warning.
Solution:
- Use the `[[maybe_unused]]` attribute to indicate the value is unused.
Note:
- Functions taking a `(void)` argument list have also been changed to
`()` because this is not needed and shows up in the same grep
command.
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.
