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
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
When files where placed in outside of the project root, they would
appear empty because the label in the tree would differ from the
actual file path relative to the root.
Fixes#5471.
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. :^)
Previously, HackStudio exited whenever a LanguageServer crashed.
Now, we disconnect all clients from that language server instance and
show a nice notification.
We now also look at the available declarations from included header
files when autocompleting names.
Additionally, you can now request autocomplete on an empty token, which
brings up all available names, starting from the inner-most scope.
... and performs preprocessing on the source code before parsing.
To support this, we are now able to keep track of multiple
files in the autocomplete engine. We re-parse a file whenever it is
edited.
FileDB wraps the access to the contents of project files.
When asked to fetch a file, FileDB will either return its in-memory
model of the file if it has been "opened" by the language-server
protocol, or otherwise fetch it from the filesystem.
Previously, the cpp language server did not pledge "rpath" and got
access to the contents of files whenever they were opened by the
language client.
However, features like inspection of header files require the language
server to get the content of files that were not opened by the client.
The language server now pledges rpath but makes sure to only unveil
the project's directory and /usr/include.
For example, FindInFilesWidget.h mentions GUI::TableView, but did not include
it. On the other hand, all source files that include FindInFilesWidget.h
also include TableView.h, so the issue is only cosmetical.
This is a little bit messy but the basic idea is:
Syntax::Highlighter now has a Syntax::HighlighterClient to talk to the
outside world. It mostly communicates in LibGUI primitives that are
available in headers, so inlineable.
GUI::TextEditor inherits from Syntax::HighlighterClient.
This let us to move GUI::JSSyntaxHighlighter to JS::SyntaxHighlighter
and remove LibGUI's dependency on LibJS.
Add a new wrapping mode to the TextEditor that will wrap lines at the
spaces between words.
Replace the previous menubar checkbox 'Wrapping Mode' in HackStudio and
the TextEditor with an exclusive submenu which allows switching between
'No wrapping', 'Wrap anywhere' and 'Wrap at words'. 'Wrap anywhere' (the
new 'Wrap lines') is still the default mode.
Setting the wrapping mode in the constructors of the TextEditorWidget
and HackStudio has been removed, it is now set when constructing the
menubar actions.
When opening a file in the tree view with _double click_, the file name
was not the same as opening the same file with _right click > Open_.
This caused the opne_files_view to have the same file in it, but with
two different names.
Previously, if a new LanguageClient was created & destroyed, the
ServerConnection to the language server would be left without an
attached LanguageClient.
As a result, auto-completion results would not be updated in the UI.
Starting with this commit, the LanguageClient holds a WeakPtr to the
previous LanguageClient that was attached to the ServerConnection,
and re-attaches it after detaching itself.
