TreeView was still partly sticking to the pre-cursor way of using the
first index in the selection as the implied cursor. This patch fixes
all of the TreeView code to operate on the cursor instead.
This makes trees behave much more intuitively when alternating between
mouse and keyboard interaction.
Instead of filling the whole row with selection color, only fill behind
the text. This gives a snugger, more focused appearance.
For embedders that want the entire row to get filled with the selection
color when selected, they can opt in to the old behavior by calling
TreeView::set_should_fill_selected_rows(). This is used by Profiler.
Move the wrapping logic to get_item_rects(). This makes mouse events
able to hit the wrapped labels, and various other little things stop
glitching out as well.
Also, instead of having a per-line width when wrapping icon names,
make the text rect wide enough to fit every line.
This allows us to communicate details about invalid tokens to the parser
without having to invent a bunch of specific invalid tokens like
TokenType::InvalidNumericLiteral.
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. :^)
