This is a first crude attempt at allowing reloading without exiting
fped. This should be useful when writing a design as text and using
the GUI only to visualize it.
Reload is only enabled (in the File menu) if the file doesn't have
the "MACHINE-GENERATED" header.
Known bugs:
- exits on parse errors
- leaks memory badly
- current frame is reset to root
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

fine. Anyway, here's a new debug construct (%frame) and a bunch of new
regression tests.
- fpd.y, fpd.l, README: added new directive %frame to link frames also to other
frames than the current one (like in the GUI)
- gui_tool.h, gui_tool.c: export is_parent_of
- test/frame_ref: regression tests to ensure that frame order remains valid,
even if we reference late from early 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

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("").

- .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 !

- README: added that loops can also execute zero times
- accept labels only at the beginning of a line
- rectangles and lines no longer use the bounding box for drawing (caused
offset problems since we now correct for the line width)

- added creation of pads
