This allows the address bar to "select all" when initially gaining focus
as Firefox and Chrome do. A future improvement on this would be for the
Widget class to mange and provide focus transition as part of the events
instead of the UrlBox class. Currently focus is updated before the event
is provided to the UrlBox class.
This ensures that the user can't copy/cut text from password boxes which
would reveal the password. It also makes sure that the undo/redo actions
stay disabled because it's difficult to reason about what these do
exactly without being able to see the result.
Anyone who inherits from `GUI::Clipboard::ClipboardClient` will receive
clipboard notifications via `clipboard_content_did_change()`.
Update ClipboardHistoryModel, TextEditor and TerminalWidget to inherit
from this class.
While under insert mode, Ctrl-U deletes all characters between the first
non-blank character of the line and the cursor.
Implement delete_from_line_start_to_cursor() in TextEditor. Then, call
the method in VimEditingEngine via its pointer to an instance of
TextEditor.
In Vim, Ctrl-H is effectively equivalent to backspace in insert mode, as
it deletes the previous character.
This commit implements method delete_previous_char() to TextEditor.
delete_char() already exists in EditingEngine, but it deletes the
next character rather than the previous. delete_previous_char() is then
called from within VimEditingEngine.
In Vim's insert mode, Ctrl-W deletes the word before the cursor, like
Ctrl-Backspace. Unlike Ctrl-Backspace, if only whitespace exists between
the end of the word and the cursor, the word will be deleted with the
whitespace.
To do so, this commit introduces two methods: delete_previous_word() for
TextEditor and first_word_before() for TextDocument, where the former
depends on the latter. delete_previous_word() is then called in
VimEditingEngine.
Making use of the new FileSystemAccessServer we are able to use
unveil without restricting our ability to open and save files.
A file argument will be unveiled automatically however all other files
require user action via the FileSystemAccessServer to gain access.
This patch adds the member variable m_substitution_code_point to
GUI::TextEditor. If non-zero, all gylphs to be drawn will be substituted
with the specified code point. This is mainly needed to support a
PasswordBox.
While the primary use-case is for single-line editors, multi-line
editors are also supported.
To prevent repeated String construction, a m_substitution_string_data
members has been added, which is an OwnPtr<Vector<u32>>. This is used as
a UTF-32 string builder. The substitution_code_point_view method uses
that Vector to provide a Utf32View of the specified length.
If something happens in response to on_change that causes the widget
to get unparented, creating a GUI::Painter will fail since it can't
find the window to paint into.
Since painting only cares about the syntax highlighting spans, what we
really want is to ensure that spans are up-to-date before we start
painting.
The problem was that rehighlighting and the on_change hook were bundled
together in an awkward lazy update mechanism. This patch fixes that by
decoupling rehighlighting and on_change. Rehighlighting is now lazy
and only happens when we handle either paint or mouse events. :^)
Fixes#8302.
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.
This adds support for shift+return key combo in single line TextEditor
fields. Used in this case for searching backwards/forwards in the
Terminal find window.
This moves the calculation of selected words that was originally
in the TextEditor application to TextEditor in LibGUI.
This allows all applications with text editors to get
this number without having to calculating it themselves.
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.
This was quite unreliable before. Changes to the undo stack's modified
state are now reflected in the document's modified state, and the
GUI::TextEditor widget has its undo/redo actions updated automatically.
UndoStack is still a bit hard to understand due to the lazy coalescing
of commands, and that's something we should improve upon (e.g with more
explicit, incremental command merging.) But for now, this is a nice
improvement and undo/redo finally behaves in a way that feels natural.
Have TextDocument listen for state changes on the internal undo stack,
and forward those to all clients via a new virtual function.
This simplifies updating the can_undo / can_redo states of TextEditor.
This patch moves selection updates outside movement functions in
EditingEngine. Previously, movement functions would automatically
update the selection based on whether the Shift key was pressed down
during movement. However, not all EditingEngine subclasses want that;
VimEditingEngine being a good example (because all selection is handled
in visual mode).
Therefore, this patch moves all selection updating to
EditingEngine::on_key(). Subclasses wishing to provide custom movement
and selection semantics should override it (and VimEditingEngine already
does).

This was a kludge to paint ComboBox editors before the advent of
accessory windows, isn't being used anymore, and was inadvertently
letting two ComboBoxes paint as if both had focus.
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
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.
This API was a mostly gratuitous deviation from POSIX that gave up some
portability in exchange for avoiding the occasional strlen().
I don't think that was actually achieving anything valuable, so let's
just chill out and have the same open() API as everyone else. :^)
