d99b1a9ea0 LibHTML: Add the outline of a CSS stylesheet object graph. 2019-06-20 23:25:25 +02:00

2e2b97dc8a LibHTML: Add layout() overrides for LayoutText and LayoutBlock. 2019-06-20 23:00:26 +02:00

8cb0c765ca LookupServer: Use a CFile for loading /etc/hosts. 
This fixes an issue with the lines having extra bytes at the end due after
converting from ByteBuffer to String.

a7dc1a7d6b AK: Make StringImpl a bit smaller. 
There's no need for a member char* m_characters if we always store them
in the inline buffer. So with this patch, we now do.
After that, rearrange the members a bit for ideal packing. :^)

8c0ae711d8 Kernel+LibC: Make page fault crashes a bit more readable. 
We'll now try to detect crashes that were due to dereferencing nullptr,
uninitialized malloc() memory, or recently free()'d memory.
It's not perfect but I think it's pretty good. :^)

Also added some color to the most important parts of the crash log,
and added some more modes to /bin/crash for exercising this code.

Fixes #243.

15bea7153a Kernel: Symbolicate the crash address too, not just the call stack. 
Also print it in shiny red to make it extra easy to spot. :^)
Fixes #244.

9149a519f5 printf: Support printing negative values with %f or %g. 2019-06-18 14:47:52 +02:00

203f8e5320 AK: Add IPv4Address(NetworkOrdered<dword>) constructor. 2019-06-18 11:40:39 +02:00
Andreas Kling
d9a48b5916 AK: Move IPv4Address from Kernel/Net/ to AK/ since it's quite useful. 2019-06-18 11:28:48 +02:00

9f7c11710f printf: Treat %g as %f for now. 2019-06-18 09:46:39 +02:00

aa3df518e7 AK: Rename JsonObject::to_string() and pals to serialized(). 
And the variant that serializes into a StringBuilder is called serialize().

15fa4f1c55 AK: ScopeGuard.h needs StdLibExtras.h 2019-06-18 09:31:14 +02:00

4ee39d6292 AK: Override StringImpl's operator delete to silence valgrind. 2019-06-18 09:26:36 +02:00
Andreas Kling
92cda74724 AK: Fix leak in JsonValue::operator=(JsonValue&&). 
Amusingly I introduced this leak while explaining that this type of leak is
a common bug, and saying I'm used to looking for it. :^)
 2019-06-18 09:22:19 +02:00
Andreas Kling
4147394dcb AK: Add JsonValue(const char*). 
This should obviously become a string, but if we don't have it, constructing
from a string literal ends up creating a boolean value.
 2019-06-18 09:11:31 +02:00
Andreas Kling
1a761ea4fd AK: Add JsonValue(unsigned) ctor and as_string(). 2019-06-18 08:55:58 +02:00

114768562a AK: Including <AK/kstdio.h> should pull in <stdio.h> etc on host builds. 2019-06-18 08:53:26 +02:00
Andreas Kling
28a4963242 AK: Make ASSERT_NOT_REACHED() work nicely in host builds. 2019-06-18 08:52:21 +02:00

ee347effac AK: Use a single StringBuilder throughout JSON serialization. 2019-06-17 21:36:54 +02:00
Andreas Kling
3b9fcab1af VisualBuilder: Switch to JSON for the form output. 
This makes widgets-within-widgets straightforward instead of confusing.
The UI doesn't actually let you put widgets inside one another just yet,
but at least now the output format won't be a problem. :^)

04a8fc9bd7 AK: Add some classes for JSON encoding. 
This patch adds JsonValue, JsonObject and JsonArray. You can use them to
build up a JsonObject and then serialize it to a string via to_string().

This patch only implements encoding, no decoding yet.

9fa4e779ff LibM: Rewrite trigonometric functions. 
This way they seem to actually work as expected ;)

502c54e39a Add a simple spray fill tool 
Could do with some more tweaking no doubt, and it'd be nice to have a
circular spray, but this is better than nothing.

0db2f3cbe6 LibHTML: Add a Frame class, start fleshing out recursive layout. 
Layout is initiated from Frame::layout(). It makes the document's layout
node as wide as the frame, and then we'll take it from there.

cf17e385b5 PaintBrush: Allow editing palette colors by ctrl-clicking them. 
Maybe the ColorDialog class could be fashioned into something generally
usable in LibGUI, but for now it lives in the PaintBrush app. :^)
