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.
This patch fixes a bug where double-clicking on a word in a TextEditor
with syntax highlighting would also select an additional character after
the word. This also simplifies the logic for double- and
triple-clicking.
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.
The autocomplete box closes on its own when the user tries to hover
over it because text_editor consideres hovering over the box to be
a leave_event. This commit stops that from happening.
This fixes#7946
Previously, TextEditor::write_to_file() would not mark its document
as unmodified if the file size was 0. This caused a desync in the
Text Editor app between the window's is_modified state and the
TextEditor's. It's already noted in the comments of the app's
save action code that propagating the modified state automatically
would be good, and it would solve issues like this, but I'm not yet
familiar enough with the code to try a change like that.
This fixes an off-by-one error in TextEditor's rendering of the syntax
highlighting as generated by Syntax::Highlighter and its subclasses.
Before, a single character span was e.g. (0-3) to (0-3), but this was
considered invalid by GUI::TextRange. Now, a single character span would
be e.g. (0-3) to (0-4).
This fix requires all Syntax::Highlighter subclasses to be adjusted, as
they all relied on the previous implementation. This will then also fix
a bug where single-character HTML tags wouldn't be highlighted.
This replaces ctype.h with CharacterType.h everywhere I could find
issues with narrowing conversions. While using it will probably make
sense almost everywhere in the future, the most critical places should
have been addressed.
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.
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 patches fixes a crash of the Userland/TextEditor where it would
crash when deleting a range spanning two lines. This was because the
TextEditor would delete the range and modify the cursor position
before clearing the selection. This would trigger a status bar update
with the invalid selection.
This commit unifies methods and method/param names between the above
classes, as well as adds [[nodiscard]] and ALWAYS_INLINE where
appropriate. It also renamed the various move_by methods to
translate_by, as that more closely matches the transformation
terminology.
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).

neither by space, nor by underscore:

This patch makes everything consistent by replacing every other variant
of these with the proper one. :^)
Previously, this was updating the suggestions before processing the keys
and whatever changes they caused, making the suggestions stale until the
periodic auto-autocomplete timer fired (if enabled).
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.
This makes drawing text with spans a lot faster.
The previous implentation went character by character and then
checked every span whether it contained the current character.
This implentation asumes that the spans are sorted and goes span by
span drawing all the characters contained at once.
Any spans that are out of order will be ignored!
Note: text wrapping is not (yet) supported
In line wrapping mode, the same column refers both to the end of a
visual line and the beginning of the subsequent visual line. This
meant that the cursor couldn't move to the beginning of a visual
line. Now, we only let the cursor go to the end of a physical line,
not the visual line.
Closes#4786
(...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.
If the cursor Y position is < 0 in content coordinate space, we should
always map that to the first line of the file.
This fixes unexpected cursor behavior when dragging the selection above
the top of the document.
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.
