This commit also completely reworks the execution, highlighting and
completion model to work with the new AST.
New additions:
- $(...) stdout captures
- fd>&fd redirections
- fd>&- redirections (close fd)
- read-write redirections (<> path)
- completely event-based execution
- the weird idea of allowing the user to redirect the shell's own fds
- variables in strings
- local variables
- minimal list support
- adding hyperlinks to all paths that exist
After adding the scrolling feature, content available space reduced and
thus the bitmap size was always larger, than the inner size.
This lead to the horizontal scrollbar always beeing engaged.
FileBackedFileSystem is one that's backed by (mounted from) a file, in other
words one that has a "source" of the mount; that doesn't mean it deals in
blocks. The hierarchy now becomes:
* FS
* ProcFS
* DevPtsFS
* TmpFS
* FileBackedFS
* (future) Plan9FS
* BlockBasedFS
* Ext2FS
The WebContentView widget now inherits from GUI::ScrollableWidget and
will pass its scroll offset over to the WebContent process as it's
changing. This is not super efficient and can get a bit laggy, but it
will do fine as an initial scrolling implementation.
Just like the single-process Web::PageView widget, WebContentView also
paints scrolled content by translating the Gfx::Painter.
This patch adds a PreviewMode enum with the following values:
- None
- Markdown
- HTML
This makes it a bit more logical to implement exclusive behavior.
This function relies on visible_content_rect() which could previously
return rectangles with negative size. This was causing TableViews to
scroll down a little bit when assigning a model to them.
Also tweak the logic so we scroll a 0x0 rect into view, giving a
slightly nicer final position.
During app teardown, the Application object may be destroyed before
something else, and so having Application::the() return a reference was
obscuring the truth about its lifetime.
This patch makes the API more honest by returning a pointer. While
this makes call sites look a bit more sketchy, do note that the global
Application pointer only becomes null during app teardown.
To make the plain text we copy out from LibWeb look at least somewhat
like its original form, let's insert newlines at <br> elements and when
we exit a block-level element.
This is far from perfect, but seems to work pretty okay.
This works by finding the very first and very last LayoutText nodes
in the layout tree and then setting the selection bounds to those two
nodes. For some reason it gets glitchy if we set the very first and
very last *LayoutNode* as the selection bounds, but I didn't feel like
investigating that too closely right now.
