As part of this, the CodeDocument now keeps track of the kind of
difference for each line. Previously, we iterated every hunk every time
the editor was painted, but now we do that once whenever the diff
changes, and then save the type of difference for each line.
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 :^)
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. :^)
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.

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 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.
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.
The documentation tooltip and parameters hint tooltip initialization
functions are now fallible and now call try_set_main_widget
instead of set_main_widget. They are only called by Editor's new
custom try_create function.
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.
When you press Ctrl+P while the cursor is inside the parameters list of
a function call site, HackStudio will request the C++ language server
to retrieve the parameters of the called function.
The result is displayed in a tooltip window, with the current argument
in bold font.
Previously, whenever Editor::set_document() was called, we destroyed
the previous LanguageClient instance of the editor and created a new
one.
We now check if the language of the existing LanguageClient matches the
new document, and if so we do not create a new LanguageClient instance.
This fixes an issue where doing "goto definition" would crash
HackStudio. This was probably introduced in 44418cb351.
The crash occurred because when doing "goto definition", we called a
AK::Function callback from the LanguageClient, which internally called
Editor::set_document().
Editor::set_document() destroyed the existing LanguageClient, which
cased a VERIFY in Function::clear() to fail because we were trying to
destroy the AK::Function object while executing inside it.
Gutter -- a space left of the text, before the ruler -- is not a part of
the ruler, nor should it be treated as such. This commit implements
gutter handling in LibGUI::TextEditor as part of mild cleaning up of the
gutter handling (breakpoint icons) in HackStudio's Editor.
This commit also enables separate theming of the gutter.
Renamed the virtual from "on_edit_action" to "will_execute" so it
doesn't clash with our convention for Function hook names.
Also tighten the parameter type to GUI::TextDocumentUndoCommand
since that's the only kind of command it will receive.
You can now right click in HackStudio's editor while debugging and
have the option to instantly move the current execution position to
the current line.
This implements a dialog that can be used to evaluate a JS expression
in the HackStudio's Debugger context. It also implements simple
C++ Variable <-> JS Value conversion, allowing for JS expressions
to read/write variables in the debugger scope.
Currently, C++ structs are mapped to JS objects by way of a JS proxy,
however this leads to issues when printing, so this will be changed
in a later commit.

This was done with the `ambr` search and replace tool.

The Locator now keeps a cache of the declared symbol in a document.
The language client updates that cache whenever it gets an update from
the language server about declared symbols.
This allows searching for symbol declarations in the Locator, in
addition to file names.
Closes#5478
The C++ LanguageServer can now find the matching declaration for
variable names, function calls, struct/class types and properties.
When clicking on one of the above with Ctrl pressed, HackStudio will
ask the language server to find a matching declaration, and navigate
to the result in the Editor. :^)
