2020-02-07HackStudio: Disallow invalid indices when typing into the locatorAndreas Kling
The locator was a bit crashy since it would allow you to navigate to invalid indices.
2020-02-07LibGUI+HackStudio: Move syntax highlighting from HackStudio to LibGUIAndreas Kling
This patch introduces the GUI::SyntaxHighlighter class, which can be attached to a GUI::TextEditor to provide syntax highlighting. The C++ syntax highlighting from HackStudio becomes a new class called GUI::CppSyntaxHighlighter. This will make it possible to get C++ syntax highlighting in any app that uses a GUI::TextEditor. :^) Sidenote: It does feel a bit weird having a C++ lexer in a GUI toolkit library, and we'll probably end up moving this out to a separate place as this functionality grows larger.
2020-02-06LibGUI: Remove leading G from filenamesAndreas Kling
2020-02-06IPCCompiler: Put message classes in the Messages namespaceAndreas Kling
2020-02-06LibCore: Remove leading C from filenamesAndreas Kling
2020-02-06LibIPC: Remove leading I from filenamesAndreas Kling
2020-02-06LibGUI: Rename {H,V}BoxLayout => {Horizontal,Vertical}BoxLayoutAndreas Kling
2020-02-06LibGUI: Add HorizontalSlider and VerticalSlider convenience classesAndreas Kling
2020-02-06LibGUI: Add HorizontalSplitter and VerticalSplitter convenience classesAndreas Kling
2020-02-06LibGfx: Prefer using Gfx::Bitmap::load_from_file instead of load_png()Andreas Kling
Code that just wants to open a Gfx::Bitmap from a file should not be calling the PNG codec directly.
2020-02-06LibGfx: Unpublish Gfx::Size from the global namespaceAndreas Kling
2020-02-06LibGfx: Unpublish Gfx::Point from global namespaceAndreas Kling
2020-02-06LibGfx: Unpublish Gfx::Rect from global namespaceAndreas Kling
2020-02-06LibGfx: Rename from LibDraw :^)Andreas Kling
2020-02-06LibDraw: Put all classes in the Gfx namespaceAndreas Kling
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. :^)
2020-02-05LibC: Add posix_openpt(), grantpt() and unlockpt()Andreas Kling
This makes getting a pseudoterminal pair a little bit more portable. Note that grantpt() and unlockpt() are currently no-ops, since we've already granted the pseudoterminal slave to the calling user. We also accept O_CLOEXEC to posix_openpt(), unlike some systems. :^)
2020-02-05LibIPC: Put all classes in the IPC namespace and remove the leading IAndreas Kling
2020-02-05IPCCompiler: Remove outdated FIXMEAndreas Kling
We actually do support longer messages now since the message encoder grows dynamically.
2020-02-05IPCCompiler: Encode String length as i32, with <0 meaning null String()Andreas Kling
2020-02-05AK+IPCCompiler: Get rid of BufferStream overloads for size_tAndreas Kling
Since BufferStream is about creating specific binary stream formats, let's not have a flaky type like size_t in there. Instead, clients of BufferStream can cast their size_t to the binary size they want to use. Account for this in IPCCompiler by making String lengths always 32-bit.
2020-02-05IPCCompiler: Encode/decode string lengths as native size_t, not intjoshua stein
2020-02-02ProfileViewer: Only show live allocations by defaultAndreas Kling
For memory profiles, we now keep track of which allocations are still live at the end of the selected timeline range and only show those. This is really cool, I have to admit. :^)
2020-02-02ProfileViewer: Add basic support for loading "perfcore" filesAndreas Kling
"perfcore" is the file that the kernel generates after a process that was recording performance events has exited. This patch teaches ProfileViewer how to load (and symbolicate!) those files so that we can look at them. This will need a bunch more work to make it truly useful.
2020-02-02LibGUI: Put all classes in the GUI namespace and remove the leading GAndreas Kling
This took me a moment. Welcome to the new world of GUI::Widget! :^)
2020-02-02LibCore: Put all classes in the Core namespace and remove the leading CAndreas Kling
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.
2020-02-02LibGUI: Add GHBoxLayout and GVBoxLayout convenience classesAndreas Kling
2020-01-27LibGUI: Add 64-bit signed integer support to GVariantAndreas Kling
What was previously the "Int" type is now "Int32" and "Int64".
2020-01-23GTextEditor: Move "Go to line" feature from HackStudio into GTextEditorAndreas Kling
This is a handy feature for any multi-line GTextEditor, so let's just have it in the base widget. :^) Fixes #1122.
2020-01-19Kernel: Let's say that everything < 3GB is user virtual memoryAndreas Kling
Technically the bottom 2MB is still identity-mapped for the kernel and not made available to userspace at all, but for simplicity's sake we can just ignore that and make "address < 0xc0000000" the canonical check for user/kernel.
2020-01-18Meta: Add license header to source filesAndreas Kling
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.
2020-01-17Kernel: Add "accept" pledge promise for accepting incoming connectionsAndreas Kling
This patch adds a new "accept" promise that allows you to call accept() on an already listening socket. This lets programs set up a socket for for listening and then dropping "inet" and/or "unix" so that only incoming (and existing) connections are allowed from that point on. No new outgoing connections or listening server sockets can be created. In addition to accept() it also allows getsockopt() with SOL_SOCKET and SO_PEERCRED, which is used to find the PID/UID/GID of the socket peer. This is used by our IPC library when creating shared buffers that should only be accessible to a specific peer process. This allows us to drop "unix" in WindowServer and LookupServer. :^) It also makes the debugging/introspection RPC sockets in CEventLoop based programs work again.
2020-01-16HackStudio: add exec pledgejoshua stein
2020-01-16HackStudio: set sane $PATH early to include /usr/local/binjoshua stein
Launching from the terminal inherits $PATH which includes /usr/local/bin, but launching from the system menubar doesn't, so HackStudio wasn't finding make installed from ports.
2020-01-12Applications+DevTools+MenuApplets: Drop "unix" pledge when possibleAndreas Kling
Now that the "unix" pledge is no longer required for socket I/O, we can drop it after making the connections we need in a program. In most GUI program cases, once we've connected to the WindowServer by instantiating a GApplication, we no longer need "unix" :^)
2020-01-11HackStudio: Use pledge()Andreas Kling
2020-01-07Themes: Support rubberband selection theming0xtechnobabble
2020-01-02Build: HOST_CXX -> USE_HOST_CXXjoshua stein
Allow HOST_CXX to be passed to make which will be the actual host C++ compiler used, such as 'make HOST_CXX=clang++'.
2020-01-02ProfileViewer: Interpret addresses >= 0xc0000000 as kernel framesAndreas Kling
2019-12-30LibIPC: Let's start building custom message codecs for LibIPCAndreas Kling
Instead of using ByteBuffer (which always malloc() their storage) for IPC message encoding, we now use a Vector<u8, 1024>, which means that messages smaller than 1 KB avoid heap allocation entirely.
2019-12-28HackStudio: Check for make command on startupConrad Pankoff
2019-12-28HackStudio: Add file list context menu and file removal actionConrad Pankoff
2019-12-26HackStudio: Fix failure to open filesAndreas Kling
Use FileSystemPath to figure out that "./foo.cpp" == "foo.cpp"
2019-12-25Build: support library and generator dependenciesjoshua stein
Instead of directly manipulating LDFLAGS, set LIB_DEPS in each subdirectory Makefile listing the libraries needed for building/linking such as "LIB_DEPS = Core GUI Draw IPC Core". This adds each library as an -L and -l argument in LDFLAGS, but also adds the library.a file as a link dependency on the current $(PROGRAM). This causes the given library to be (re)built before linking the current $(PROGRAM), but will also re-link any binaries depending on that library when it is modified, when running make from the root directory. Also turn generator tools like IPCCompiler into dependencies on the files they generate, so they are built on-demand when a particular directory needs them. This all allows the root Makefile to just list directories and not care about the order, as all of the dependency tracking will figure it out.
2019-12-24LibGUI+LibDraw: Add "Palette" concept for scoped color themingAndreas Kling
GApplication now has a palette. This palette contains all the system theme colors by default, and is inherited by a new top-level GWidget. New child widgets inherit their parents palette. It is possible to override the GApplication palette, and the palette of any GWidget. The Palette object contains a bunch of colors, each corresponding to a ColorRole. Each role has a convenience getter as well. Each GWidget now has a background_role() and foreground_role(), which are then looked up in their current palette when painting. This means that you no longer alter the background color of a widget by setting it directly, rather you alter either its background role, or the widget's palette.
2019-12-24LibDraw: Add Selection and SelectionText system theme colorsAndreas Kling
2019-12-23WindowServer+LibGUI: Implement basic color themingAndreas Kling
Color themes are loaded from .ini files in /res/themes/ The theme can be switched from the "Themes" section in the system menu. The basic mechanism is that WindowServer broadcasts a SharedBuffer with all of the color values of the current theme. Clients receive this with the response to their initial WindowServer::Greet handshake. When the theme is changed, WindowServer tells everyone by sending out an UpdateSystemTheme message with a new SharedBuffer to use. This does feel somewhat bloated somehow, but I'm sure we can iterate on it over time and improve things. To get one of the theme colors, use the Color(SystemColor) constructor: painter.fill_rect(rect, SystemColor::HoverHighlight); Some things don't work 100% right without a reboot. Specifically, when constructing a GWidget, it will set its own background and foreground colors based on the current SystemColor::Window and SystemColor::Text. The widget is then stuck with these values, and they don't update on system theme change, only on app restart. All in all though, this is pretty cool. Merry Christmas! :^)
2019-12-23HackStudio: Show the project name as the root in the project treeAndreas Kling
2019-12-23HackStudio: Sort the project tree alphabeticallyAndreas Kling
I had to turn the tree nodes into RefCounted objects since it's not possible to quick_sort() a Vector<OwnPtr<T>> at the moment.
2019-12-23HackStudio: Show the project file list in a tree viewAndreas Kling
Replace the boring list view with an awesome tree view :^)
2019-12-20Build: clean up build system, use one shared Makefilejoshua stein
Allow everything to be built from the top level directory with just 'make', cleaned with 'make clean', and installed with 'make install'. Also support these in any particular subdirectory. Specifying 'make VERBOSE=1' will print each ld/g++/etc. command as it runs. Kernel and early host tools (IPCCompiler, etc.) are built as object.host.o so that they don't conflict with other things built with the cross-compiler.
