Instead of simply outputting the character. This way, we get proper padding
support and other niceties strings enjoy.

This patch adds the parsing of double values to the JSON parser.
There is another char buffer that get's filled when a "." is present
in the number parsing. When number finished, a divider is calculated
to transform the number behind the "." to the actual fraction value.
|
|
This allows to retrieve a default value for items thare are not
available in the json object.

String.h no longer pulls in StringView.h. We do this by moving a bunch
of String functions out-of-line.
|
|
|
|
And share the code with String by moving the logic to StringUtils. :^)

FlyString is a flyweight string class that wraps a RefPtr<StringImpl>
known to be unique among the set of FlyStrings. The class is very
unoptimized at the moment.
When to use FlyString:
- When you want O(1) string comparison
- When you want to deduplicate a lot of identical strings
When not to use FlyString:
- For strings that don't need either of the above features
- For strings that are likely to be unique

This patch adds a generic StringBuilder::join(separator, collection):
Vector<String> strings = { "well", "hello", "friends" };
StringBuilder builder;
builder.join("+ ", strings);
builder.to_string(); // "well + hello + friends"
|
|
Now it's possible to use range-based for loops with String and StringView.
|
|
This is a bit hackish, but sometimes these files stick around and mess
up rebuilds.

This was not used by anyone. If we ever need it, we can bring it back.

Move the "fast memcpy" stuff out of StdLibExtras.h and into Memory.h.
This will break a ton of things that were relying on StdLibExtras.h
to include a bunch of other headers. Fix will follow immediately after.
This makes it possible to include StdLibExtras.h from Types.h, which is
the main point of this exercise.
|
|
We can use __builtin_memset() without including <string.h>.
This is pretty neat, as it will allow us to reduce the header deps
of AK templates a bit, if applied consistently.
Note that this is an enabling change for an upcoming #include removal.

Use this instead of uintptr_t throughout the codebase. This makes it
possible to pass a FlatPtr to something that has u32 and u64 overloads.
|
|
This allows you to select a type based on a compile-time condition.
|

|

This was causing some obvious-in-hindsight but hard to spot bugs where
we'd implicitly convert the bool to an integer type and carry on with
the number 1 instead of the actual value().
|
|
Instead of set(const JsonValue&) and set(JsonValue&&), just do
set(JsonValue) and let callers move() if they want. This removes some
ambiguity and the compiler is smart enough to optimize it anyway.
|
|
|
|
Now it actually defaults to "a < b" comparison, instead of forcing you
to provide a trivial less-than comparator. Also you can pass in any
collection type that has .begin() and .end() and we'll sort it for you.

Provide wrappers in String and StringView. Add some tests for the
implementations.

Provide wrappers in the String and StringView classes, and add some tests.
|
|
Also add tests for CircularDeque.
|

Now that Vector uses size_t, we can remove a whole bunch of redundant
casts to size_t.
|
|
Add an extra out-parameter to shbuf_get() that receives the size of the
shared buffer. That way we don't need to make a separate syscall to
get the size, which we always did immediately after.

This feels a lot more consistent and Unixy:
create_shared_buffer() => shbuf_create()
share_buffer_with() => shbuf_allow_pid()
share_buffer_globally() => shbuf_allow_all()
get_shared_buffer() => shbuf_get()
release_shared_buffer() => shbuf_release()
seal_shared_buffer() => shbuf_seal()
get_shared_buffer_size() => shbuf_get_size()
Also, "shared_buffer_id" is shortened to "shbuf_id" all around.

This commit replaces SinglyLinkedListIterator::universal_end() with an
empty SinglyLinkedListIterator(). Piano needs this in order to
initialize a member array of iterators without 84 lines of
universal_end().

This should make stuff like placement new work correctly when building
outside of Serenity. This stuff is a bit delicate due to the weirdly
staged toolchain build at the moment. Hopefully we can unify this stuff
in the future.

The not initialized variables can lead to compiler warnings that
become errors with the -Werror flag.
|
|
|
|
Also rework its API's to return Optional<size_t> instead of int with -1
as the error value.
