This fixes a bug where lines starting with a space would get parsed as
"level 0" headings - it would not find a "#" and therefore never
increase the level counter (starting at zero), which then would cause
the check for "space after #" pass (again, there is no "#").
Eventually we would get funny results like this:
<h0>[n-1 spaces]oops!</h0>
Also ASSERT(level > 0) in the Heading constructor.
Instead of files disappearing after you switch to something else,
we now keep track of them in a little ListView below the project tree.
You can return to any previously opened file by activating it in the
open files list. :^)
waitid() *may* be called many times if a job does not exit, so only
assert this fact when the job has in fact exited.
Also allows Background nodes to contain non-execute nodes.
This is implemented in Line::Editor meaning not only the Shell will
respect it, but also js, Debugger etc.
Possible values are "ignorespace", "ignoredups" and "ignoreboth", as
documented in Shell-vars(7), for now.
The default value for the anon user (set in .shellrc) is "ignoreboth".
This allows us to easily re-use history loading and saving in other
programs using Line::Editor, as well as implementing universally
recognized HISTCONTROL.
g_scheduler_lock cannot safely be acquired after Thread::m_lock
because another processor may already hold g_scheduler_lock and wait
for the same Thread::m_lock.
It's possible that we broadcast an IPI message right at the same time
another processor requests a halt. Rather than spinning forever waiting
for that message to be handled, check if we should halt while waiting.
This enables the APIC timer on all CPUs, which means Scheduler::timer_tick
is now called on all CPUs independently. We still don't do anything on
the APs as it instantly crashes due to a number of other problems.
The qualified name of a font is "<Family> <Size> <Weight>". You can
get the QN of a Font via the Font::qualified_name() API, and you can
get any system font by QN from the GUI::FontDatabase. :^)
`snprintf` returns the number of characters that would have been written
had the buffer been large enough.
It's a common trick to call `snprintf(nullptr, 0, ...)` to measure how
large a buffer has to be.
Thus the return value is not zero but fourteen.
The configuration key [DNS] Nameserver has been renamed to Nameservers
and accepts a comma-separated list of nameserver addresses, which will
be queried in the given order until a response has been received.
The new default value is still Cloudflare's 1.1.1.1 as well as their
secondary DNS server 1.0.0.1.
did_timeout is a bool& parameter of lookup() that used to be set when
the UDP connection timed out, but this behaviour was broken in e335d73.
I replaced it with a more useful 'did_get_response' parameter that is
being set after the UDP socket connected, sent its request and got a
response - it might still be bogus data but we know the communication
was successful.
This make buttons look extra clickable when hovered by lifting up their
icons (-1,-1) and painting a little icon-shaped shadow under them.
Partially inspired by the Office XP toolbars, although we don't go all
the way with the faux-hyperlink stuff that was all the rage back then.
Newlines after line continuation were inserted into the string
literals. This patch makes the parser ignore the newlines after \ and
also makes it so that "use strict" containing a line continuation is
not a valid "use strict".
If a project contains "foo.cpp" but we can't open "foo.cpp", just go
with an empty text document for now, and we'll create "foo.cpp" when
the user saves.
