While you are typing in HackStudio, we re-lex the C++ as you type,
so this means we also need to keep re-checking for matching curlies and
parentheses at the cursor.
Fixes#769 (although it's not optional, because it's too cool. :^)
This works for C++ syntax highlighted text documents by caching the C++
token type in a new "arbitrary data" member of GTextDocumentSpan.
When the cursor is placed immediately before a '{' or immediately after
a '}', we highlight both of these brace buddies by changing their
corresponding spans to have a different background color.
..and spans can also now have a custom background color. :^)
You can now manipulate the widget selection either by clicking and
dragging the widgets using the cursor tool, or by interacting with
the form widget tree view. :^)
Using the default cursor bitmap as the cursor tool icon in HackStudio
was predictably making it impossible to tell if it's the real cursor
or not. Replace it with a color-inverted cursor. :^)
We now use the magical widget registry to factory-construct widgets and
place them into the form.
This will need all kinds of work, but it's nice that the mechanism is
working as intended.
I'll be reconstructing parts of the VisualBuilder application here and
then we can retire VisualBuilder entirely once all the functionality
is available in HackStudio.
Note that you are not allowed to remove the very last editor.
These keybinds are all temporary while I figure out what the right ones
should be. I'm not exactly sure how, but it'll reveal itself. :^)
The idea here is to decouple the document from the editor widget so you
could have multiple editors being views onto the same document.
This doesn't work yet, since the document and editor are coupled in
various ways still (including a per-line back-pointer to the editor.)
This patch adds Editor (subclass of GTextEditor) and EditorWrapper.
An EditorWrapper is a composite widget that adds a little statusbar
above an Editor widget. The statusbar is used for showing the filename
and the current cursor position. More things can definitely be added.
To get to the currently active editor, call current_editor().
You can also get to the current editor's wrapper by calling..
current_editor_wrapper(). Which editor is current is determined by
which was was last focused by the user.
By "hide" I really mean collapse them down to 24px height. We grow them
to a normal size when they're needed. The user is also free to resize
them at will.
This keeps them out of the way when you just want to do editing. :^)
Add a list of hard-coded standard types (including AK types) and show
them in a different style.
Rehighligt the file whenever it changes. (This is very inefficient but
makes it much easier to experiment.)
Also keep tweaking the colors. :^)
When we open a file whose name ends in ".cpp", we now pass the contents
through CppLexer, which produces a CppToken stream.
Those CppTokens are then converted into GTextEditor::Spans and handed
over to GTextEditor which then colorizes the source code accordingly.
This is pretty neat. :^)
I broke this when factoring out the find-in-files widget into its own
class. This patch adds a main_editor() global getter for grabbing at
the main GTextEditor from wherever you are.
Have Ctrl+Shift+F open the find-in-files widget and focus the text box
so you can start entering text right away.
Also make it do a search when you press the return key.
Projects now contain a set of TextDocument objects. Each TextDocument
represents a member file in the project. TextDocuments may not have
their file contents loaded at all times, but they will be loaded on
demand when calling TextDocument::contents().
"Find in files" works by iterating over the documents in the project
and calling find(needle) on each one. The return value from find() is
a vector of line numbers where the needle was found.
This is obviously going to need a bunch more work. :^)
