Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

LibVT: Factor out terminal emulation from Terminal to make it reusable Now that we're bringing back the in-kernel virtual console, we should move towards having a single implementation of terminal emulation. This patch rips out the emulation code from the Terminal application and turns it into the beginnings of LibVT. The basic design idea is that users of VT::Terminal will implement and provide a VT::TerminalClient subclass to handle presentation-specific things. We'll need to iterate on this, but it's a start. :^)

void create_window();
Port Terminal to LibGUI. To facilitate listening for action on arbitrary file descriptors, I've added a GNotifier class. It's quite simple but very useful: GNotifier notifier(fd, GNotifier::Read); notifier.on_ready_to_read = [this] (GNotifier& fd) { // read from fd or whatever else you like :^) }; The callback will get invoked by GEventLoop when select() says we have something to read on the fd.
2019-02-10 13:28:39 +00:00
void flush_dirty_lines();
Plumb menu item activation events from WindowServer to clients. GMenu now has an "on_item_activation" callback that fires whenever one of its items are activated. The menu item identifier is used to distinguish between items. Use this to implement font switching in Terminal. :^)
2019-02-12 09:08:35 +00:00

Add concept of size increments to windowing system. Use this to implement incremental resizing for Terminal so that we only ever resize to fit a perfect number of rows and columns. This is very nice. :^)

LibVT: Make TerminalWidget logically focusable when not a main widget TerminalWidget was relying on the "window became active/inactive" events from WindowServer to update its own internal focus state. Unfortunately those events are only sent to the window's main widget, so this was not working when the TerminalWidget was embedded deeper in a widget tree. This patch hooks the focusin and focusout events and uses those to set the focus state when received. This makes TerminalWidget behave nicely in both configurations. This design is kind of a workaround for this awkward focus architecture and we should figure out something better in the long term.

LibCore: Put all classes in the Core namespace and remove the leading C I've been wanting to do this for a long time. It's time we start being consistent about how this stuff works. The new convention is: - "LibFoo" is a userspace library that provides the "Foo" namespace. That's it :^) This was pretty tedious to convert and I didn't even start on LibGUI yet. But it's coming up next.

RefPtr<Core::Notifier> m_notifier;
WindowServer: Support windows with alpha channels. And per-WSWindow opacity. This patch also adds a Format concept to GraphicsBitmap. For now there are only two formats: RGB32 and RGBA32. Windows with alpha channel have their backing stores created in the RGBA32 format. Use this to make Terminal windows semi-transparent for that comfy rice look. There is one problem here, in that window compositing overdraw incurs multiple passes of blending of the same pixels. This leads to a mismatch in opacity which is obviously not good. I will work on this in a later patch. The alpha blending is currently straight C++. It should be relatively easy to optimize this using SSE instructions. For now I'm just happy with the cute effect. :^)

AK: Rename the common integer typedefs to make it obvious what they are. These types can be picked up by including <AK/Types.h>: * u8, u16, u32, u64 (unsigned) * i8, i16, i32, i64 (signed)

bool m_needs_background_fill { true };
Terminal+LibGUI: Make the terminal cursor blink. Added a GTimer class to help with this. It's just a simple GObject subclass that sets up an event loop timer and invokes a callback on timeout.

bool m_cursor_blink_state { true };
LibVT: Make TerminalWidget's automatic size policy updates optional When embedding a TerminalWidget, you might not want it to automatically update its own size policy based on the exact terminal buffer size. This behavior is now passed as a flag to the TerminalWidget constructor which makes it behave nicely both inside HackStudio and in Terminal.

Make a preparation pass for variable-width fonts.

LibDraw: Put all classes in the Gfx namespace I started adding things to a Draw namespace, but it somehow felt really wrong seeing Draw::Rect and Draw::Bitmap, etc. So instead, let's rename the library to LibGfx. :^)

RefPtr<Gfx::Font> m_bold_font;
LibVT: only use default bold font if it's the same size as our font When the new font is a different size, just use that font for bold glyphs as well. It would be nice to find a matching bold version of the new font automatically in the future.

Terminal: Implement basic history scrollback This code needs some optimization work to reduce the amount of repaints but the history feature basically works, which is cool :^) Fixes #431.

Terminal+LibVT: Switch Terminal to using explicit copy/paste actions Instead of implicitly copying whatever you select, and pasting when you middle-click, let's have traditional copy and paste actions bound to Ctrl+Shift+C and Ctrl+Shift+V respectively.
