Instead of the previous only-escape-with-backslashes, extend the
escaping to one of:
- No escape
- Escape with backslash
- Escape with "\xhh" if control character that isn't easily represented
as \X
- Escape with "\uhhhhhhhh" if unicode character that is too big to
represent as "\xhh".
Fixes#6986.
The Kernel/.gitignore file is a remnant of the prior build system,
where the kernel.map was written directly to to the Kernel folder.
The run.sh was also under Kernel so pcap files and others would get
dropped there when running the system under qemu.
None of these situations are possible now, so lets get rid of it.
We now follow nested page tree nodes to find all of the actual
page dicts, whereas previously we just assumed the root level
page tree node contained all of the page children directly.
This commit introduces the ability to parse the document catalog dict,
as well as the page tree and individual pages. Pages obviously aren't
fully parsed, as we won't care about most of the fields until we
start actually rendering PDFs.
One of the primary benefits of the PDF format is laziness. PDFs are
not meant to be parsed all at once, and the same is true for pages.
When a Document is constructed, it builds a map of page number to
object index, but it does not fetch and parse any of the pages. A page
is only parsed when a caller requests that particular page (and is
cached going forwards).
Additionally, this commit also adds an object_cast function which
logs bad casts if DEBUG_PDF is set. Additionally, utility functions
were added to ArrayObject and DictObject to get all types of objects
from the collections to avoid having to manually cast.
This commit adds a parser as well as the Reader class, which serves
as a utility to aid in reading the PDF both forwards and in reverse.
The parser currently is capable of reading xref tables, as well as
all values. We don't really do anything with any of this information,
however.
This commit is the start of LibPDF, and introduces some basic structure
objects. This emulates LibJS's Value structure, where Value is a simple
class that can contain a pointer to a more complex Object class with
more data. All of the basic PDF objects have a representation.
We were not substituting the window modified marker ("[*]") in the
title strings we were sending to WM clients. This caused the Taskbar
to show pre-substitution window titles for the Text Editor application.
This patch moves the window title resolution to Window::compute_title()
which is then used throughout.
Also update the window switcher for good measure. The window switcher
doesn't visualize this information at the moment, but we generally do
this when any window state changes.
Instead of trying to update only the little bit that changes, let's
have a function that updates all the window menu items in one go.
It's just a couple of string and boolean assignment, and the real
cost is performing the subsequent menu redraw, which remains the same.
Previously, to get the globally available declarations in a document
(including declarations from headers), we would have to recursively
walk the #include tree and get the declarations of each included
document.
To improve upon this, we now store a HashTable of globally available
declaration from included header files in each document, and populate
it when we first process the document.
Before this, invoking simple autocomplete actions in code documents
that had a very large #include tree (e.g when <LibGUI/Widget.h> was
included) hang the CppLanguageServer process and used 100% CPU until
the process ran out of memory.
Now, the autocomplete request in that situation returns immediately :^)
* tBodies - returns a HTMLCollection of all tbody elements
* createTBody - If necessary, creates a new tbody element
and add it to the table after the last tbody element
* tFoot - Getter for the tfoot element
The setter is not currently implemented
* createTFoot - If necessary, creates a new tfoot element
and add it to the table after any tbody elements
* deleteTFoot - If a tfoot element exists in the table, delete it
* tHead - Getter for the thead element
The setter is not currently implemented
* createTHead - If necessary, creates a new thead element
and add it to the table after any caption or colgroup elements,
but before anything else
* deleteTHead - If a thead element exists in the table, delete it
* caption - Getter and setter for the caption element
* createCaption - If necessary, creates a new caption element
and add it to the table
* deleteCaption - If a caption element exists in the table, delete it
rows returns a HTMLCollection of all the tr elements contained within
the table.
We leave the SameObject attribute off the attribute in the IDL as we
cannot currently return the same HTMLCollection every time (see the
FIXME on DOM::Document::applets)
The WrapperGenerator currently does not correctly handle the default
value for the type long on insertRow. Currently not specifying the
index will insert a row at index 0.
Tests against and writes to the depth buffer when GL_DEPTH_TEST is
enabled via glEnable(). Currently fragment z is always compared against
existing depth with GL_LESS.
