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

- removed root_frame. "frames" now takes its place.
- removed frame->prev. In those few cases where we need the previous frame (for
deletion and dumping), we walk the list or recurse.
- the list of frames is now in GUI order, not file order.
- when reading the .fpd file, put the root frame first and leave it there.
- instead of walking the frames list and excluding the root frame by testing
frame->name, just start at frames->next
- likewise, instead of testing !frame->name just use frame == frames

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
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5939 99fdad57-331a-0410-800a-d7fa5415bdb3
they referenced. As a band-aid, we now explicitly keep track of which vectors
have been dumped, and defer objects accordingly. A more correct solution would
be to properly abstract the partial order algorithms (along with the heuristics
for maximizing the number of ".") and to implement it properly.
- fpd.y (debug_item): new rule for %dump and %exit, which can appear also among
measurements
- fpd.y (frame_items, measurements): rearranged grammar to allow debug_item
also in measurements. To avoid ambiguities, the "measurements" section can no
longer be empty, but it can be omitted as a whole.
- obj.h, dump.c (later, recurse_vec, order_frame): vectors now also have a
"dumped" flag which is used in "later" to defer dumping an object until all
the vectors it depends on have been dumped.

created file. This is a precaution against accidently saving to a manual work,
which would change the structure and remove all comments.
- fped.h, fped.c, file.c: moved declaration of save_file_name into shared
header
- dump.h, dump.c (MACHINE_GENERATED): moved header marking machine-generated
files into shared macro
- gui.c (save_as_fpd): added "Save as" dialog
- fped.h, fped.c (load_file), gui.c: disable "Save" if editing a file that
doesn't have the machine-generated header

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("").
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5919 99fdad57-331a-0410-800a-d7fa5415bdb3
- dump.c (print_obj): removed free(s2) left over from before the reduction of
allocations
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5728 99fdad57-331a-0410-800a-d7fa5415bdb3
deleted. The new algorithm checks for collisions and also reduces the number
of allocations.
- dump.c (generate_name): store the name in the vector being named
- dump.c (generate_name): compare the new name against all names in use
- dump.c (base_name, obj_base_name, print_label): don't allocate the name
- dump.c: changed all users of the above functions accordingly
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5715 99fdad57-331a-0410-800a-d7fa5415bdb3
- .fpd file format: new directive "unit" to set the default unit
- new selection was too aggressive - make it only rearrange settings if we also
fail the second vector search
- gui_draw_pad_text: calculation of height vs. width lost too much precision,
causing pad text to be rotated arbitrarily
- drag_new_vec: display distance in mil if unit is mil
- end_new_raw_vec: store distance in mil if unit is mil
- gridify: use a 10 mil grid if unit is mil
- ps_hline: corrected gsave/grestore mismatch
- Makefile: made "all" a prerequisite of "install"
- Postscript output now mentions the default unit (if set)
- ps_package: height and width were swapped, oopsie !
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5525 99fdad57-331a-0410-800a-d7fa5415bdb3
- postscript.c: fixed algorithm in "center"
- dump.c: reorder frames if we would end up with forward-references
- sc89.fpd, fbga.fpd: changed "part" to new "package"
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5490 99fdad57-331a-0410-800a-d7fa5415bdb3
- README: added build prerequisites
- "part name" is now more correctly called "package name"
- changed keyword "part" to "package"
- removed inst_debug and struct inst_ops.debug functions - never really used
them anyway
- we can now generate multiple packages from a single file
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5478 99fdad57-331a-0410-800a-d7fa5415bdb3
- item ordering heuristics failed to properly use "."
- updated description of "need" in dump.c
- saved fbga.fpd and sc89.fpd with new ordering
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5427 99fdad57-331a-0410-800a-d7fa5415bdb3
space than it needs
- dump.c: separated ordering function from actual printing
- added list of vectors and object (on the right side of the variables)
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5423 99fdad57-331a-0410-800a-d7fa5415bdb3
the frame name when auto-generating them
- moved file I/O from gui.c to file.c
- ps_line used the wrong endpoint coordinate
- option -k makes fped write KiCad non-interactively
- option -p makes fped write Postscript non-interactively
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5418 99fdad57-331a-0410-800a-d7fa5415bdb3
- dump any undumped non-measurements before the measurements
- finished sc89.fpd, with the full set of measurements
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5415 99fdad57-331a-0410-800a-d7fa5415bdb3
- removed support for old-style measurements
- new-style measurements are now embedded in "struct obj", so we can dump and
delete them
- "measxy" is now called "meas"
- updated examples to use new-style measurements
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5412 99fdad57-331a-0410-800a-d7fa5415bdb3
- also dump the part name
- if given a zero-length vector, draw_arrow now draws a vertical arrow instead
of overflowing
- fixed angle calculation when drawing and selecting arcs
- redraw the screen after deselecting when we begin dragging
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5395 99fdad57-331a-0410-800a-d7fa5415bdb3
- dump objects only after all the vectors they reference have been dumped
- instead of relying on clever algorithms to dump each object only once, just
mark them
- left "dump" enabled in "main", oops
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5392 99fdad57-331a-0410-800a-d7fa5415bdb3
operation, not just one object at a time
- 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.
