Previously files in the open files view would stay open from the
previous project, and files in the new project with the same name as
files in the old one would be inaccessible, with the old ones showing
up instead. Now all files and open editors are closed before a new
project is opened.
Fixes#9103
.html files were recognised before -- the name was shown on
the statusbar, but it didn't actually enable the syntax highlighting.
This also sneaks a highlighting for JSON using JS highlighting.
It isn't technically correct, but so does TextEditor. :^)
This enables further work on implementing KASLR by adding relocation
support to the pre-kernel and updating the kernel to be less dependent
on specific virtual memory layouts.
Splitter does weird things when you resize and then remove children.
This works around the limitation by forcing at least one of the editors
to fill the space. It's janky, but at least doesn't result in the last
editor not filling the window.
This implements almost all instructions related to the FPU, including
all MMX instructions as well.
A lot of these were copied and adjusted from the SoftCPU implementation.
The next big milestone would be QNan detection and ShadowValue handling.
This removes all the hard-coded kernel base addresses from userspace
tools.
One downside for this is that e.g. Profiler no longer uses a different
color for kernel symbols when run as a non-root user.
Depending on the values it might be difficult to figure out whether a
value is decimal or hexadecimal. So let's make this more obvious. Also
this allows copying and pasting those numbers into GNOME calculator and
probably also other apps which auto-detect the base.
Applications previously had to create a GUI::Menubar object, add menus
to it, and then call GUI::Window::set_menubar().
This patch introduces GUI::Window::add_menu() which creates the menubar
automatically and adds items to it. Application code becomes slightly
simpler as a result. :^)
This reverts commit cfef3040fb.
It looks like although this does improve things, it also degrades the
experience and messes with the usability, especially for large amounts
of processes.
Need to come back to this with a more holistic fix.
As threads come and go, we can't simply account for how many time
slices the threads at any given point may have been using. We need to
also account for threads that have since disappeared. This means we
also need to track how many time slices we have expired globally.
However, because this doesn't account for context switches outside of
the system timer tick values may still be under-reported. To solve this
we will need to track more accurate time information on each context
switch.
This also fixes top's cpu usage calculation which was still based on
the number of context switches.
Fixes#6473
This commit makes LibRegex (mostly) capable of operating on any of
the three main string views:
- StringView for raw strings
- Utf8View for utf-8 encoded strings
- Utf32View for raw unicode strings
As a result, regexps with unicode strings should be able to properly
handle utf-8 and not stop in the middle of a code point.
A future commit will update LibJS to use the correct type of string
depending on the flags.
The backtrace view expects that there is always a valid selection. This
is not true when we execute a step in the debugger. Therefore we need
to check if we have a valid selection in the on_selection_change
handler.
Today the profile viewer timeline view has a static size, which is
computed as half the height of the window given it has two root widgets.
Instead the timeline view should shrink to only consume the size that
each process timeline consumes.
The IPCCompiler was using GENERATE_DEBUG_CODE, which was missing from
AK/Debug.h.in, and plain old DEBUG. Let's just use the one that
was already in the debug header, but unused.
Context menu entries like evaluate expression and
move execution to line action should only be enabled
when a debug session is running. Otherwise they should
be disabled.
This commit disables the run button while we
are in debug mode. Otherwise the stop button
gets disabled when we run the program while
we are in debug mode. This would prevent us
from exiting the debug mode.
Previously almost all fields were public and were directly accessed by
the Parser and CppComprehensionEngine.
This commit makes all fields of AST node types private. They are now
accessed via getters & setters.
`fpu_get` returns a long double and `fpu_set` expects a long double as
its parameter, and the X87 FPU uses long doubles as its internal
storage, meaning the `FABS` operates on them. This means the correct
intrinsic function for implementing it is `__builtin_fabsl`.
We already do this in most places, so the style should be consistent.
Also, Clang does not like it, as this could cause an unexpected compile
error if some statements are added to the default label or a new label
is added above it.
While structs being forward declared as classes is not strictly an
issue, Clang complains as this is not portable code, since some ABIs
treat classes declared as `class` and `struct` differently.
It's easier to fix these than to reason about explicitly disabling
another warning.
It might be the case that we are passing non-movable/non-copyable things
through IPC. In this case, Clang will emit a warning as it can't
generate the requested default move/copy ctor for the IPC message.
To fix this, we use a `#pragma` to make the compiler silently ignore our
request.
The same was the case with the three-way comparison in `Screen`. Since
we don't use the three-way comparison operator anywhere else in our
codebase, we simply use the `==` operator instead.
