I never liked the various hacks I had come up with for representing
resource handles in Ruamoko. Structs with an int were awkward to test,
pointers and ints could be modified, etc etc. The new @handle keyword (@
used to keep handle free for use) works just like struct, union and
enum in syntax, but creates an opaque type suitable for a 32-bit handle.
The backing type is a function so v6 progs can use it without (all the
necessary opcodes exist) and no modifications were needed for
type-checking in binary expressions, but only assignment and comparisons
are supported, and (of course) nil. Tested using cbuf_t and QFile: seems
to work as desired.
I had considered 64-bit handles, but really, if more than 4G resource
objects are needed, I'm not sure QF can handle the game. However, that
limit is per resource manager, not total.
Now that the data is fetched from the correct location, the locals view
is useful again :). However, there seems to be a problem with array
views: not sure they're showing the correct data as I was getting
unexpected values in the display but normal vars seem to be ok.
While the .tmp defs weren't too much clutter in v6p progs, the .arg defs
in Ruamoko progs make for a lot of noise. Showing only user defs (those
without a leading .) makes for a much more usable locals display.
And other related fields so integer is now int (and uinteger is uint). I
really don't know why I went with integer in the first place, but this
will make using macros easier for dealing with types.
They are both gone, and pr_pointer_t is now pr_ptr_t (pointer may be a
little clearer than ptr, but ptr is consistent with things like intptr,
and keeps the type name short).
And fix an error in floatview.
The z-transform program is so I can test out my math and eventually
develop some hopefully interesting sound generators.
Support for finding the first address associated with a source line was
added to the engine, returning 0 if not found.
A temporary breakpoint is set and the progs allowed to run free.
However, better handling of temporary breakpoitns is needed as currently
a "permanent" breakpoint will be cleared without clearing the temporary
breakpoing if the permanent breakpoing is hit while execut-to-cursor is
running.
Pressing F8 (or n) while the debug target was running would cause it to
stop at that point. While it's certainly desirable to stop a runaway
target on demand, that should be with a different input. Now, commands
that start the target running are ignored while the target is running.
No commands for when the target is running have been implemented yet,
but the provision is there.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
I decided that stopping in between function calls that are on the same
line is a good thing as it gives a chance to skip over the first but
step into the second.
It currently dies when single stepping or exiting due to EditBuffer's
retain count not getting incremented when initialized. This is because
EditBuffer is initialized in C and thus does not call Object's -init.
While trying to build a view without deriving from it was a neat idea,
it doesn't work so well because a view really needs to know how to draw
itself. This even fixes the segfault when stepping past the end of the
program.
For now it just manages type encodings via their encoding string,
ensuring types are fetched from the target only once, if at all (may
already have the type due to it being common).
Things were getting rather cluttered with everything being qwaq-* and
all in one directory. Now most have lost the qwaq- prefix and have been
moved into subdirectories (non-recursive make).
