This was unintuitive, and only useful in a few cases. In the majority,
users had to immediately call `stop()`, and several who did want the
timer started would call `start()` on it immediately anyway. Case in
point: There are only two places I had to add a manual `start()`.
DeprecatedFlyString relies heavily on DeprecatedString's StringImpl, so
let's rename it to A) match the name of DeprecatedString, B) write a new
FlyString class that is tied to String.
We changed elapsed() to return i64 instead of int as that's what
AK::Time::to_milliseconds() returns, causing a bunch of implicit lossy
conversions in callers. Clean those up with a mix of type changes and
casts.
Simplify a lot of uses of ElapsedTimer by converting the callers to
elapsed_time from elapsed, as the AK::Time returned is better for unit
conversions and comparisons against constants.
These functions return the deprecated `Core::File` class, so let's mark
it as such to avoid possible confusion between future non try_*
functions which will use Core::Stream family classes and to possibly
grab someone's attention. :^)
Rip that bandaid off!
This does the following, in one big, awkward jump:
- Replace all uses of `set_main_widget<Foo>()` with the `try` version.
- Remove `set_main_widget<Foo>()`.
- Rename the `try` version to just be `set_main_widget` because it's now
the only one.
The majority of places that call `set_main_widget<Foo>()` are inside
constructors, so this unfortunately gives us a big batch of new
`release_value_but_fixme_should_propagate_errors()` calls.
Without this, the "Widget not registered" error stays visible if the
widgets defined by the GML do not themselves fill with their background
color.
Also tidied up some unused includes.
In doing so, this removes all uses of the Encoder's stream operator,
except for where it is currently still used in the generated IPC code.
So the stream operator currently discards any errors, which is the
existing behavior. A subsequent commit will propagate the errors.
These instances were detected by searching for files that include
stdlib.h, but don't match the regex:
\\b(_abort|abort|abs|aligned_alloc|arc4random|arc4random_buf|arc4random_

l|strtoull|system|unlockpt|unsetenv|wcstombs|wctomb)\\b
(Without the linebreaks.)
This regex is pessimistic, so there might be more files that don't
actually use anything from the stdlib.
In theory, one might use LibCPP to detect things like this
automatically, but let's do this one step after another.
In 7c5e30daaa, the focus was "only" on
Userland/Libraries/, whereas this commit cleans up the remaining
headers in the repo, and any new badly-formatted include.
It may be handy to have some sort of storage inspector at some point but
for now, it doesn't make sense to open a database file. So only allow
opening script files, and don't make assumptions on their extension.
This adds a combo box to the action toolbar to allow for entering a
database name manually or selecting from the list of existing databases.
The action to run a script is now disabled while we are not connected to
a database.
It's not particularly useful to see the word count of a SQL script,
except for when displaying the number of selected words. This changes
SQLStudio to behave exactly like HackStudio in this regard. We will use
segment 0 to display the selected text stats (if any) and segment 2 for
the cursor position. Segment 1 will be used in an upcoming commit for
the current SQL connection status. We also now handle displaying action
text the same way as HackStudio.
Most actions do not need to care about whether there is an open editor
tab, as we can (and should) disable those actions when there isn't an
open tab. We can also hide the verify_cast handling inside a helper
function.
The underlying Core::Stream methods require the bytes passed in to be
non-empty. Simply opening the file is enough to ensure the file is
created with empty contents if the editor's text is empty.
In both applications, display the SQL statement that failed to parse.
For the REPL, ensure the REPL prompts the user for another statement.
For SQLStudio, we don't continue executing the script as it likely does
not make sense to run statements that come after a failed statement.
Currently, the generated IPC decoders will default-construct the type to
be decoded, then pass that value by reference to the concrete decoder.
This, of course, requires that the type is default-constructible. This
was an issue for decoding Variants, which had to require the first type
in the Variant list is Empty, to ensure it is default constructible.
Further, this made it possible for values to become uninitialized in
user-defined decoders.
This patch makes the decoder interface such that the concrete decoders
themselves contruct the decoded type upon return from the decoder. To do
so, the default decoders in IPC::Decoder had to be moved to the IPC
namespace scope, as these decoders are now specializations instead of
overloaded methods (C++ requires specializations to be in a namespace
scope).
There were a total of 20 fixmes that were removed. This required me to
create a `initialize_all()` function for the HackStudioWidget class
that could actually propagate the errors forward to the Serenity::Main
function for the HackStudio application.
All the fixmes dealt with loading icons for the various actions
possible.
This should not be a failure that keeps HackStudio from running, but
currently, if the icons cannot be loaded HackStudio fails to open.
This fixes a bug where hackstudio's language server will crash upon
clicking the 'cut' button when no text is selected. This was because
the actions were not disabled on empty selection.
We now disable the actions depending on if there is empty selection
inside current tab. We update the cut/copy/paste buttons' actions when
changing tabs.
We couldn't compile a project after creating it, because the project
builder was still holding a reference to the previous freed project.
Fixes: #15715
This change also removes the path argument from the GitWidget
constructor because otherwise, the app wouldn't work now, as it doesn't
yet know the project path.
But it'll be set right away in open_project(), so nothing's lost. :^)
About half of the usages were not using `force` anyways, and the other
half presumably just got confused about what "force" really means in
this context (which is "ignore nonexistent files").
The only 'legitimate' user, which is `rm`, instead now handles this
completely internally instead.
This syscall will be used later on to ensure we can declare virtual
memory mappings as immutable (which means that the underlying Region is
basically immutable for both future annotations or changing the
protection bits of it).
Note that this still keeps the old behaviour of putting things in std by
default on serenity so the tools can be happy, but if USING_AK_GLOBALLY
is unset, AK behaves like a good citizen and doesn't try to put things
in the ::std namespace.
std::nothrow_t and its friends get to stay because I'm being told that
compilers assume things about them and I can't yeet them into a
different namespace...for now.
This generally seems like a better name, especially if we somehow also
need a better name for "read the entire buffer, but not the entire file"
somewhere down the line.
We previously passed both OperandSize and AddressSize to the
constructor.
Both values were only ever 32-bit at construction.
We used AddressSize::Size64 to signify Long mode which was needlessly
complicated.
We've been sending the values converted to a string, but now that the
Value type is transferrable over IPC, send the values themselves. Any
client that wants the value as a string may do so easily, whereas this
will allow less trivial clients to avoid string parsing.
Currently, when clients connect to SQL server, we inform them of any
errors opening the database via an asynchronous IPC. But we already know
about these errors before returning from the connect() IPC, so this
roundabout propagation is a bit unnecessary. Now if we fail to open the
database, we will simply not send back a valid connection ID.
Disconnect has a similar story. Rather than disconnecting and invoking
an asynchronous IPC to inform the client of the disconnect, make the
disconnect() IPC synchronous (because all it does is remove the database
from the map of open databases). Further, the only user of this command
is the SQL REPL when it wants to connect to a different database, so it
makes sense to block it. This did require moving a bit of logic around
in the REPL to accommodate this change.
In order to execute a prepared statement multiple times, and track each
execution's results, clients will need to be provided an execution ID.
This will create a monotonically increasing ID each time a prepared
statement is executed for this purpose.
When storing IDs and sending values over IPC, this changes SQLServer to:
1. Stop using -1 as a nominal "bad" ID. Store the IDs as unsigned, and
use Optional in the one place that the IPC needs to indicate an ID
was not allocated.
2. Let LibIPC encode/decode enumerations (SQLErrorCode) on our behalf.
3. Use size_t for array sizes.
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.
One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Before this we just added a new tab and left the `(Untitled)` tab in the
background. Now we instead check that it hasn't been modified and that
it's empty; if both these conditions are true we replace the blank
editor with the newly opened one.
This resolves a 3+ year old FIXME related to tooltip documentation
search paths. By default we now search man3 in addition to man2 that we
previously only searched.
Rename sql_statement to prepare_statement and statement_execute to
execute_statement. The former aligns more with other database libraries
(e.g. Java's JDBC prepareStatement). The latter reads less awkwardly.
This patch will switch cursor to DragCopy when a user enters a widget
while dragging file(s), giving them a visual clue that it *might* be
dropped into this widget.
This is a rather naive approach, as the cursor icon will change for any
kind of file, as currently programs don't know the drag contents before
dropping it. But after all I think it's better than nothing. :^)
Otherwise, we end up propagating those dependencies into targets that
link against that library, which creates unnecessary link-time
dependencies.
Also included are changes to readd now missing dependencies to tools
that actually need them.
Even though the toolchain implicitly links against -lc, it does not know
where it should get LibC from except for the sysroot. In the case of
Clang this causes it to pick up the LibC stub instead, which might be
slightly outdated and feature missing symbols.
This is currently not an issue that manifests because we pass through
the dependency on LibC and other libraries by accident, which causes
CMake to link against the LibC target (instead of just the library),
and thus points the linker at the build output directory.
Since we are looking to fix that in the upcoming commits, let's make
sure that everything will still be able to find the proper LibC first.
The syscalls are renamed as they no longer reflect the exact POSIX
functionality. They can now handle setting/getting scheduler parameters
for both threads and processes.
This is done by adding a new window type (Popup) and using it for the
combobox list window. Other incorrect uses of the Tooltip window type
have also been updated to use the new window type.
Previously, Playground would always preview the rendered GML in a frame
next to the editor. This can be annoying when trying to work with small
or large widget hierarchies since the size of the preview is tied to the
size of the editor. Now there is a view menu which allows you to toggle
between the frame or a separate window which can be resized independent
of the editor.
Even though this almost certainly wouldn't run properly even if we had
a working kernel for AARCH64 this at least lets us build all the
userland binaries.
We previously put the generated headers in SOURCES, which did not mark
them as GENERATED (and did not produce a proper dependency).
This commit moves all generated headers into GENERATED_SOURCES, and
removes useless header SOURCES.
This fixes issue #14429. The editor actions were not given a parent as
scope so defaulted to global. Because HackStudio can have multiple
editors and even multiple editor tab widgets, I chose the
VerticalSplitter that all editor tab widgets get added to as the parent.
With a Widget set as the parent, the action gets WidgetLocal scope and
allows the embedded terminals to receive shortcuts.
Thanks to Andreas for doing a quick look at this and pointing in the
right direction during an Office Hours stream :)
Previously, every Editor instance had two instances of tooltip windows
& `OutOfProcessWebView`s, one for documentation and one for parameter
hints.
They were initialized with the Editor, which slowed down creation of new
tabs.
We use a single global tooltip & OOPWV instance that is shared between
tabs.
Closes#15488

Previously if the user closed the last open tab in the last TabWidget
then the open file action would stop working until they explicitly
went to the View menu and added a new editor group.
Before this commit there was an attempt at preventing the user to
close the last open tab by hiding its close button, this didn't
account for the many other ways one could close it though.
Previously when trying to open a file from the tree view the file
would open in the currently selected tab, substituting the file
we were previously reading.
This change makes it so that clicking on a file from the tree view
opens it in a new tab, or selects the tab containing that file if
it's already open in the selected editor group.
Doesn't use them in libc headers so that those don't have to pull in
AK/Platform.h.
AK_COMPILER_GCC is set _only_ for gcc, not for clang too. (__GNUC__ is
defined in clang builds as well.) Using AK_COMPILER_GCC simplifies
things some.
AK_COMPILER_CLANG isn't as much of a win, other than that it's
consistent with AK_COMPILER_GCC.
This commit does three things atomically:
- switch over Core::Account+SystemServer+LoginServer to sid based socket
names.
- change socket names with %uid to %sid.
- add/update necessary pledges and unveils.
Userland: Switch over servers to sid based sockets
Userland: Properly pledge and unveil for sid based sockets
URL had properly named replacements for protocol(), set_protocol() and
create_with_file_protocol() already. This patch removes these function
and updates all call sites to use the functions named according to the
specification.
See https://url.spec.whatwg.org/#concept-url-scheme
Currently, LibUnicodeData contains the generated UCD and CLDR data. Move
the UCD data to the main LibUnicode library, and rename LibUnicodeData
to LibLocaleData. This is another prepatory change to migrate to
LibLocale.
Before, the warning dialog would be opened after the NewProjectDialog,
leading to focus-fighting by the two windows. This fixes that and makes
the action more consistent with the standard serenity way of handling
unsaved changes by asking before the NewProjectDialog is brought up.
The way this is achieved avoids having to rewrite open_project as well.
This commit fixes a crash that would occur due to an unnamed file being
automatically saved via EditorWrapper::save(). Now, we throw up a
FilePicker::get_save_filepath.
And adjust some GML properties. Since a808cfa, splitters grow
opportunistically. Setting them to fixed sizes now quite literally
fixes them in place. Fixes immovable splitters missed in the
aforementioned commit.
Previously, Windows only understood blocking modality: Windows were
either modal, i.e., in a blocking state, or not. Windows could also
be set as Accessories or ToolWindows, attributes which technically
applied modes to their parents but were implemented ad hoc. This patch
redefines these modal effects as WindowModes and sets up some helpers.
This will let us simplify a lot of modal logic in the upcoming patches
and make it easier to build new modal effects in the future.
Windows can now set 1 of 5 modes before reification:
-Modeless: No modal effect; begins a new modal chain
-Passive: Window joins its modal chain but has no effect
-RenderAbove: Window renders above its parent
-CaptureInput: Window captures the active input role from its parent
-Blocking: Window blocks all interaction with its modal chain
States like fullscreen and tiling are dynamic and don't alter behavior
in modal chains, so they aren't included.
We previously had at least three different implementations for resolving
executables in the PATH, all of which had slightly different
characteristics.
Merge those into a single implementation to keep the behaviour
consistent, and maybe to make that implementation more configurable in
the future.
Set preferred height instead of fixed height to allow the splitter to
move.
The splitter respects set_fixed_height() after a808cfa7 "LibGUI+
Applications: Govern Splitter resizing by opportunistic growth", and
that caused the splitter in Profiler to stop working.
This patch allows to insert "%uid" in `IPC_CLIENT_CONNECTION`
declaration and in SystemServer's ini files. This pattern is replaced
then replaced by the UID of the owner of the service. It opens a path
for seamlessly managed, per-user portal.
The flame graph view used to draw only so much of the graph that could
be displayed. Change to draw the whole graph, and add a scrollbar.
Does some tricks with the scrolling to keep the bottom of the graph
fixed when resizing or double-clicking, since it works better then.
Layout cleared the list of bars in the flame graph, but didn't clear the
reference m_hovered_bar. This could cause a crash in mousedown_event()
when clicking twice: the first click caused layout, the second used
the old reference.
This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).
No functional changes.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
Error::from_string_literal now takes direct char const*s, while
Error::from_string_view does what Error::from_string_literal used to do:
taking StringViews. This change will remove the need to insert `sv`
after error strings when returning string literal errors once
StringView(char const*) is removed.
No functional changes.
This commit moves the length calculations out to be directly on the
StringView users. This is an important step towards the goal of removing
StringView(char const*), as it moves the responsibility of calculating
the size of the string to the user of the StringView (which will prevent
naive uses causing OOB access).
These were accidental (or leftover) uses of String::characters() to
construct StringViews through its StringView(char const*) constructor.
Since this constructor is due to be removed, this will no longer work.
Plus this prevents strlen from being run on these strings unnecessarily.
This commit adds support for the option described above.
The option can be seen after a right click on a TreeView item,
and it puts the item's full path in the clipboard.
This commit adds support for the option described above.
The option can be seen after a right click on a TreeView item,
and it puts the item's relative path in the clipboard (relative
to the project's root directory).
This commit has no behavior changes.
In particular, this does not fix any of the wrong uses of the previous
default parameter (which used to be 'false', meaning "only replace the
first occurence in the string"). It simply replaces the default uses by
String::replace(..., ReplaceMode::FirstOnly), leaving them incorrect.
- No underscores between word boundaries, i.e. `languageserver` and not
`language_server` for LibLanguageServer
- All lowercase, i.e. `coredump` and not `Coredump` for LibCoredump
Before this commit the close tab button, which is meant to only
show when more than one tab is open, would be present on the tab
of a new project opened after the first project.
This was due to m_all_editor_tab_widgets not being cleared when closing
the first project. This is now cleared when close_current_project() is
called.
Make the link between SQLStudio and the SQLServer so that statements
written in the editor window are executed by LibSQL when the 'Run'
button is clicked.
Add the necessary GUI elements (button, table) so that one can click a
button to run the currently-open script, and see the results in a
user-friendly table.
Set `editor->on_change` callback before opening files, otherwise the
compiled GML preview will only be available after some manual input in
the text editor.
This moves all code comprehension-related code to a new library,
LibCodeComprehension.
This also moves some types related to code comprehension tasks (such as
autocomplete, find declaration) out of LibGUI and into
LibCodeComprehension.
Also moves WebContentClient and the references to the generated IPC
descriptions, since they are all components of OutOfProcessWebView.
This patch has no functional changes.
This also makes us a bit more accurate, due to better rounding of
intermediate results.
This also gives us the flush-to-zero and denormals-are-zero SSE settings
for free! (Assuming UE is build with SSE)
This way, we can change the constant in one place. Note that this
requires the use of nested format strings, which is slightly ugly but
safe to do in this instance.
This constant is currently 3 but can be changed easily or integrated
into a user setting. Note that the results are not ideal because during
pretty-printing we're not using any nice rounding rules, so many
percentage values will actually appear as 0.399999 even though they were
rounded to three digits.
This was built on Web::InProcessWebView which is going to be removed.
Since this feature wasn't really used or maintained, let's just remove
it for now, and it can be resurrected on top of OutOfProcessWebView if
someone finds it useful enough to do that work.
This allows disassembly of binaries with SSE2 instructions in them.
SSE2 also extends all MMX instructions without affecting the mnemonic,
therefore these are just directed to the same function for now.
The UserspaceEmulator does not know this as of
this commit.
TabWidgets couldn't be used in GML properly, as the GML creation
routines didn't actually call the necessary functions in the TabWidget
to get a new tab added. This commit fixes that by making the name of the
tab a normal property, the previously introduced "title", which can be
trivially set from GML. Therefore, try_add_widget() loses an argument
(while try_add_tab doesn't, because it newly constructs the widget).
This allows us to get rid of the silly "fixing my widget tree after the
fact" code in Help and will make it super easy to use TabWidget in
future GML. :^)
This almost fully implements the SSE extension, similar to the x87 and
MMX extensions, using a separate class "SoftVPU".
Currently missing are all shadow and exception checks, as well as the
denormals-are-zero and flush-to-zero flags.
Also missing are some integer-SIMD functions.
This adds a new semantic token type, PreprocessorMacro.
Calls to preprocessor macros will now be highlighted when semantic
highlighting is enabled in Hack Studio.
The find widget appears on Ctrl+F.
It uses the GUI::TextEditor search API to search for text, which also
takes care of highlighting the search results.
The names stdout / stderr are bound to conflict with existing
declarations when compiling against other LibC's. The build on OpenBSD
is broken for this reason at the moment.
Lets rename the members to more generic names to resolve the situation.
The obsolete ttyname and ptsname syscalls are removed.
LibC doesn't rely on these anymore, and it helps simplifying the Kernel
in many places, so it's an overall an improvement.
In addition to that, /proc/PID/tty node is removed too as it is not
needed anymore by userspace to get the attached TTY of a process, as
/dev/tty (which is already a character device) represents that as well.
Previously, the ProjectBuilder searched for serenity library definitions
under Userland/Libraries.
However, not all libraries are defined there. For example, LibShell is
under Userland/Shell.
This helps make the overall codebase consistent. `class_name()` in
`Kernel` is always `StringView`, but not elsewhere.
Additionally, this results in the `strlen` (which needs to be done
when printing or other operations) always being computed at
compile-time.
Core::command() takes care of inserting the program name as the first
element in argv, and so we shouldn't include the program name in the
argument vector we give it.
The Shell's argument parsing logic tolerated the extra argument,
until 83609ad.
This fixes building serenity components in Hack Studio.
This will move the editors inside a tab widget and the user
will be able to add new editors as tabs as well as add new
tab widgets. The user will be able to easily switch between
editors as well as the tab widgets.
Currently we have a 'Project' menu with a 'New' menu in it, this tries
to organize things by just having one 'New...' sub-menu in the 'File'
menu that creates new files, projects and directories.
To solve conflicts, move 'Semantic Highlighting' to the 'View' menu.
As a result of both of these changes, remove 'Project' menu.
This commit adds "Filesystem Events" View to the Profiler. This tab
will present combined information for recorded Filesystem events.
Currently only accumulated count and duration is presented.
Duration amount currently only shows events that took over 1ms,
which means that in most cases 0 is show.
This matches the rename of RGBA32 to ARGB32. It also makes more sense
when you see it used with 32-bit hexadecimal literals:
Before:
Color::from_rgba(0xaarrggbb)
After:
Color::from_argb(0xaarrggbb)
...and implement SoftCPU::read_memory<T> with it.
This allows the MMU to read a typed object (using 1-byte reads), which
is significantly nicer to use than reading the struct fields manually.
Instead of making it hold the shadow data as another `T`, make it hold
the data as a byte array, and allow it to read the byte array as `T`.
This makes it much easier to make a "read_typed" function in the MMU.
Use the ErrorOr pattern with the Core::System wrappers to propagate more
errors from the TerminalWrapper.
The run_command method, when called with WaitForExit::Yes now returns an
error on command failure.
We now validate that the provided tag names are valid XML tag names,
and otherwise throw an "invalid character" DOM exception.
2% progression on ACID3. :^)
Also renames ServerConnectionWrapper=>ConnectionToServerWrapper
and ServerConnectionInstances=>ConnectionToServerInstances
This was done with CLion's automatic rename feature.
While trying out `ue --profile` today, I received an invalid json
profile. After poking around at the file it looks like we never close
the `events: [..` array that we generate, and thus end up with an
invalid document.
The fix is straight forward, always emit the closing brace.
Different thread highlights between widgets lead to different
visual weights between splitters, even when they have the same
width or height. This means some splitters look best at odd
sizes while others even. This sets the default spacing to the
most commonly used, depending on orientation, and adjusts
spacing for a few apps based on the new paint rect.
The most consistent look across apps requires some manual
tweaking occassionally. Knurlheads, use your discretion!
Splitters could be resized in such an order that all their remaining
children were fixed size, leading to unfillable gaps on resize events.
HackStudio and TextEditor already had logic to handle this edge case,
so this patch factors it into a general solution for all Splitters.
At least one widget is now guaranteed to be resizeable after a child
is removed.
Previously, the names of declarations where stored as a simple
StringView.
Because of that, we couldn't parse out-of-line function definitions,
which have qualified names.
For example, we couldn't parse the following snippet:
```
void MyClass::foo(){}
```
To fix this, we now store the name of a declaration with a
ASTNode::Name node, which represents a qualified named.
Previously there was some inconsistency between the apps when clicking
the "Open" action while the file wasn't saved.
Some programs (Font Editor) immediately asked you if you wanted to save
the modified file, while others (Text Editor, Hex Editor and Playground)
would show the save dialog only *after* you selected a file.
I think it's better to ask a user right away if they want to save file,
because a dialog after selecting a file should be generally related to
that selected file, like an error opening a file, an import window etc.
Previously, we stored a RefPtr to the HackStudioWidget in the
global scope.
This led to a destruction-order related use-after-free bug, where the
global HackStudioWidget instance destructed after the static-local
GUI::Clipboard instance.
When HackStudioWidget destructs it attempts to use the global Clipboard
instance, which had already been freed.
This caused the Hack Studio process to spin endlessly on exit because
it attempted to access the HashTable of the freed Clipboard object.
We now store a global WeakPtr to the HackStudioWidget instead, and
limit the lifetime of the object to the main function scope.
I've attempted to handle the errors gracefully where it was clear how to
do so, and simple, but a lot of this was just adding
`release_value_but_fixme_should_propagate_errors()` in places.
When requesting a parameter hint message with `Ctrl + p` in a file that
doesn't have a language server, we would crash.
Now, rather than verifying that we have a language server, we return
early if we don't have one.
Because the wake pipe is thread-local, it was previously not possible
to wake an event loop across a thread. Therefore, this commit
rearchitects event loop waking by making the wake function a member of
the event loop itself and having it keep a pointer to its thread's wake
pipe. The global wake() function calls wake on the current thread's
event loop.
This also fixes a bug in BackgroundAction: it should wake the event loop
it was created on, instead of the current thread's event loop.
Previously, the build directory for building serenity components was a
temporary directory in /tmp which was generated whenever a different
serenity component was built.
Instead of doing that, Hack Studio now simply uses the Build/ directory
inside the Serenity repository, similar to what is done in host builds.
This makes it so we don't re-build when switching back and forth between
different components.
It also makes it easier to inspect the build products.
When saving a new file, save_as_action will return if the filename
input was empty, but save_action would still try to save the file.
Added a guard to make sure we never try to save files with empty
filenames.
Until it becomes enough stable and performant, semantic highlighting is
disabled by default.
It can be toggled on via the "Project" menu in HackStudio.
HackStudio::Editor will now send a request to get semantic token
information to the language server whenever there's a short pause in
editing.
The result is used by the semantic c++ syntax highlighter to provide
better highlighting information.
