When using step over to step out of a function, we need to use the
address range of the step statement to determine the function which
returned said value, not the current IP, as that has already exited the
function and will consequently be that of the caller, leading to such
returns being attributed to the wrong function, and consequently also
the wrong type.
Introduce a class String which refers to shared private data that is
registered in a global hash table (in class StringPool) and use the
class consequently. This eliminates duplicate allocations for the same
string and also speeds up tests for equality. There's quite a bit
overhead for the management structures (apparently even more than for
the string data itself), but due to almost all strings being used
multiple times this still almost halves the memory usage for string
data.
In some cases /bin/open puts some additional fields in the
B_REFS_RECEIVED message, but those were completely ignored. This makes
opening paths with appended line/column numbers actually work as
expected.
When holding down Command, text under the mouse is checked whether it
looks like a URL or a local path. If so, it is highlighted and can be
clicked, which will open the URL/file. Right-clicking opens a context
menu with items for opening the link/file or copying it to the
clipboard. When additionally holding down Shift, path prefixes up to
the component under the mouse will be considered (no effect for URLs).
Changes:
* Add HyperLink class. Encapsulates a type, the address, and an
optional base address. Features an Open() method to open the address.
* Move/add some string constants to TermConst.
* Move TermView::CharClassifier to top level and rename to
DefaultCharClassifier.
* Introduce TermViewHighlight and TermViewHighlighter. The former
refers to a range of text in a TermView's text buffer. It also
contains a pointer to a TermViewHighlighter object, which specifies
how the text range shall be rendered (colors and attributes).
* TermView:
- Add respective _{Add,Remove}Highlight() methods and adjust the code
to support highlights.
- Make the selection a TermViewHighlight. At least its visual aspect
is now handled like other highlights.
- Introduce an inner TextBufferSyncLocker. It is used instead of
BAutolock when locking the text buffer to synchronize the visual
buffer with it. After it unlocks it calls
_VisibleTextBufferChanged(), if the visual text buffer has changed,
which in turn calls a new callback on the active state.
- Add WindowActivated() and ModifiersChanged() callbacks to the state
interface.
- Add new states HyperLinkState and HyperLinkMenuState which
implement the new feature.
Fix modifier issues
* add vesa.accelerant, vesa driver, ps2, isa, bios, generic_x86 for x86_64 too
* only have reiserfs, firewire, agp_gart targets for x86
* reverted hrev43950, liblocale alias shouldn't be needed anymore
