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.
Previously, find_declaration_of() only worked for AST nodes of type
Identifier. It now also works for declaration node, member variables
and function parameters.
The TokenInfo struct contains the token's position and a
"semantic type". The semantic type is a more fine-grained token type
than what's in Cpp::Token::Type.
For example, the semantic token type differentiates between a reference
to a variable and to a function parameter. In the normal Token::Type,
both would be Token::Type::Identifier.
Since VM::exception() no longer exists this is now useless. All of these
calls to clear_exception were just to clear the VM state after some
(potentially) failed evaluation and did not use the exception itself.
Now that the GML formatter is both perserving comments and also mostly
agrees to the existing GML style, it can be used to auto-format all the
GML files in the system. This commit does not only contain the scripts
for running the formatting on CI and the pre-commit hook, but also
initially formats all the existing GML files so that the hook is
successfull.
Prefixes are very much a C thing which we don't need in C++. This commit
moves all GML-related classes in LibGUI into the GUI::GML namespace, a
change somewhat overdue.
Apologies for the enormous commit, but I don't see a way to split this
up nicely. In the vast majority of cases it's a simple change. A few
extra places can use TRY instead of manual error checking though. :^)
