3bbf4610d2 AK: Add a forward declaration header
You can now #include <AK/Forward.h> to get most of the AK types as
forward declarations.

Header dependency explosion is one of the main contributors to compile
times at the moment, so this is a step towards smaller include graphs.

94ca55cefd 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.

44bc4008b7 Build: Get rid of the USERLAND define
Let's simplify things. There is now only KERNEL.
To see if you're on Serenity, check if __serenity__ is defined.

1726c17d0d AK: Handle LogStream operator<<(size_t)
This has been an annoyingly missing feature for some time.

2ad0ec325a AK: Get rid of TStyle (output styling helper for LogStream)
This didn't end up getting used, so let's get rid of it.

5122caf9a8 LogStream: Prefix userspace dbg() output with "ProcessName(PID): "
Using the new get_process_name() syscall, we can automatically prefix
all userspace debug logging.

Hopefully this is more helpful than annoying. We'll find out! :^)

9fb2a65716 AK: Rename ValueRestorer => ScopedValueRollback.
Qt had a pretty good name for this concept, so let's steal it. :^)

af81645a2a Kernel+LibC: Add a dbgputstr() syscall for sending strings to debug output.
This is very handy for the DebugLogStream implementation, among others. :^)

8075ba5064 LogStream: Add a simple-ish mechanism for colorizing and styling output.
Meet TStyle. It allows you to write things like this:

    dbg() << TStyle(TStyle::Red, TStyle::Bold) << "Hello, friends!";

Any style used will be reset along with the newline emitted when the dbg()
temporary goes out of scope. :^)

This can definitely be improved, but I think it's a decent place to start.

1b013ba699 AK: Move some of LogStream out of line & add overloads for smart pointers. 2019-07-04 07:05:58 +02:00

05cc59921a AK: Start fleshing out LogStream, a type-aware logging mechanism.
The first implementation class is DebugLogStream, which can be used like so:

    dbg() << "Hello friends, I am " << m_years << " years old!";

Note that it will automatically print a newline when the object created by
dbg() goes out of scope.

This API will grow and evolve, so let's see what we end up with :^)
