using frames to encapsulate building blocks, e.g., like macros or functions in
a programming language. Since measurements only know about the frame containing
a vector but not the frames containing that frame, invocations of this frame
from different places can only be distinguished within the min/next/max scheme.
(See the example in README.)
To eliminate this limitation, one needs a way to tell fped to consider a point
only if it has been instantiated through a certain path, e.g., by requiring
some other frames to be visited in its instantiation. This increases the number
of distinct points available for measurements.
The mechanism chosen is to qualify a measurement point with frames that lead to
it. This list of outer frames does not have to include all frames. Without
qualifying, the old behaviour results.
Note that this doesn't cover all possible ways in which a point can appear in
different roles. Multiple frame references can also result from repeating the
same frame reference in the same parent frame. The current qualification
mechanism does not allow such paths to be distinguished. However, one can
always introduce intermediate frames for this purpose.
Furthermore, repetitions create multiple instances of a point, although in what
should be considered the same role.
- fpd.l: make scanner support free-format a little better by switching back to
keyword mode after frame braces. This way, one can write a simple frame in a
single line, which is useful for regression tests.
- fpd.l, fpd.y, README, test/dbg_meas: added %meas directive to print the
result of a measurement
- fpd.y, README: measurements can now be labeled. Note that, due to limitations
of the grammar, the first measurement cannot be labeled.
- error.h, error.c (yywarn): new function for non-fatal diagnostics that always
get reported to standard error
- bitset.h, bitset.c: functions to manipulate variable-size bit sets
- meas.h, fpd.y, README, test/meas_qual: added the means to specify qualifiers
for points used in measurements
- dump.c (print_meas_base, print_meas): dump qualifiers
- delete.c (delete_references, test/del_frame): delete measurements that
reference a frame being deleted in their qualifiers
- obj.h, obj.c (enumerate_frames, instantiate): enumerate all frames so that we
have an index into the bit vector of visited frames
- meas.h, meas.c (reset_samples, meas_post), obj.c (generate_vecs,
generate_frame, instantiate): record the set of frames visited for each
sample
- meas.c (meas_post): only treat two instances of a point as equivalent if the
set of frames visited of one of them is a superset of set of the other. In
this case, keep the union of the two sets.
- meas.h, meas.c (meas_find_min, meas_find_next, meas_find_max),
test/meas_qual: instantiate_meas_pkg only select points for which all frames
in the qualification have been visited
- gui_meas.c (is_min, is_next, is_max, is_a_next): updated for above change
- inst.h, inst.c (curr_frame, propagate_bbox, add_inst, inst_begin_frame,
inst_end_frame, inst_start): renamed curr_frame to frame_instantiating to
avoid clash with curr_frame in fpd.y
- inst.h, inst.c (find_meas_hint): make global
- test/structure, test/del_vec, test/del_frame: fped now warns if a measurement
is in an unlinked frame. Changed regressions tests to avoid this warning.
- test/Common: new function expect_grep to compare only part of the output

- kicad.c (kicad_pad): move coordinate transform to new function kicad_centric
- kicad.c: added pads with holes and mechanical holes
- inst.h (struct inst.u.hole), inst.c (inst_hole): added "layers" field, like
for pads
- layer.c (LAYER_COPPER, LAYER_PASTE, LAYER_MASK): renamed to LAYER_*_TOP and
added macros for corresponding bottom layers

checks
- postscript.c: added output for holes
- icons/hole.fig: make hatched surroundings of hole look more round

infrastructure for hole objects. (Postscript and KiCad output are still
missing, and so does sanity checking.)
- gui_tool.c (new_obj_unconnected): set obj->name to NULL
- added hole objects to tool bar, all the various GUI routines, the .fpd
parser, and the .fpd dumper

of README.
- fpd.l, fpd.y, README: added debugging directives %del, %move, %print, %dump,
and %exit
- obj.h, fpd.y (find_obj, find_label, new_obj): objects can now be labeled
- obj.c (obj_anchors), inst.c (inst_anchors): gathering the list of anchors is
now a per-object function, not an instance "method". inst_anchors implements
the vector vs. object switch.
- inst.h, inst.c: removed all *_op_anchors functions
- expr.c (str_unit): in the past, we returned a malloc'ed string, but these
times are long gone. Thus, don't stralloc("").

- after instantiation, we perform sanity checks on pads and remove layers from
coppery pads that are handled by a special layer

- overlap.c: fixed overlap calculations
- gui_tool.c: end_new_pad didn't initialize the pad type

git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5626 99fdad57-331a-0410-800a-d7fa5415bdb3
- vectors now have their own struct in inst.u and don't share inst.u.rect.end
- when selecting points for measurements, use the highlighting we've already
done and don't redo all the O(n^3) searching for each mouse pointer movement
- removed debug code that printed what new measurements are like. We can now
use the code view for that.
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5552 99fdad57-331a-0410-800a-d7fa5415bdb3
- postscript.c: started adding generation of object-level frames (on-going)
- gui_canvas.c: moved call to inst_deselect into inst_select, so that
inst_select can keep track of the previous selection (if any)
- inst_select: if clicking on the location of the previous selection, try to
select the next matching item
- inst_select: if we can't find an active item, try to see if we can get
something by changing active references or - if all else fails - by
activating a different frame
- end_new_frame: reset the tool after placing the frame
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5522 99fdad57-331a-0410-800a-d7fa5415bdb3

instantiation and create a partially formed instance. During measurement
instantiation, we complete that instance.
- leak.supp: finally figured out how to write a valgrind suppression file
- fped.c: we don't need the FPED_NO_GUI kludge anymore
- fped.c: moved gui_cleanup_style to gui_main
- dereference icons (seems that this doesn't deallocate everything, though)
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5514 99fdad57-331a-0410-800a-d7fa5415bdb3

pointers, and general logic errors)
- fixed memory leak when allocating pad names in instantiation
- added "magic" environment variable FPED_NO_GUI to run fped without
initializing Gtk+
- added valgrind wrapper "leakcheck"
- delete.c: destroy() now requires a deletion to exist
- vacate_op: free string expressions
- destroy_obj: free measurement labels
- delete_references: use do_delete_obj so the we don't bump the group number
- delete_frame: delete references after deleting the frame itself, so they end
up on the stack above the frame and get destroyed first
- do_delete_vec: like above, even though it doesn't matter here
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5506 99fdad57-331a-0410-800a-d7fa5415bdb3

a little brighter
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5484 99fdad57-331a-0410-800a-d7fa5415bdb3
FOR_ALL_INSTS
- several functions only walked the active package instances, so we couldn't
access the origin of the root frame
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5482 99fdad57-331a-0410-800a-d7fa5415bdb3
- we freed a package's samples list after recalculating the number of samples,
which caused a crash after adding a new vector. We now record the original
list length in the package structure.
- when dragging a circle, offer the end point first, so that it becomes an arc
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5480 99fdad57-331a-0410-800a-d7fa5415bdb3

little access functions and open-code straightforward callbacks
- (re)stuctured hover/click/drag logic in gui_tool.c
- added optional debugging output to gui_canvas.c
- don't let a vector's base be dragged onto the vector's own end or onto one
of its children

get it back when we lose it
- improved heuristics for measx/measy: instead of looking for "next" or "max"
on secondary coordinate, pick the one that's closest. I.e., if there's a
chance to just connect with x' = 0 or y' = 0, do it.
- mouse wheel on loop value now selects next/previous value
- corrected proximity calculation for measurements
- vec/frame/meas toggle now deselects, so that we don't accidently leave a
supposedly hidden item selected
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5413 99fdad57-331a-0410-800a-d7fa5415bdb3

- vector reference counting is not needed now that we have recursive delete.
Removed it.
- completed recursive delete of vectors
- gridify: give new vectors a minimum length, so that we don't get a weird
display when starting a new footprint.
