- gui_frame.c (build_frame_label): the root frame doesn't participate in any
form of dragging, so we don't set up dragging for it at all
- gui_frame_drag.c (pick_table_cell, swap_table_cells_by_coord,
swap_table_rows): helper functions for swapping rows in a Gtk table
- gui_frame_drag.c (swap_frames, drag_frame_motion, setup_frame_drag): added
support for reordering of frames by dragging
- gui_frame_drag.c (SWAP, swap_vars, swap_values, swap_rows): removed SWAP().
Use swap() from util.h instead.
- TODO: removed frame ordering entry

inst->base and inst->u.meas.end are swapped, causing fped to crash in vec_at.
Also introduced a universal swap() function.
- util.h (swap): new swap function for arguments of any type
- gui_meas.c (begin_drag_move_meas, draw_move_meas): swap the endpoints if
moving an inverted measurement
- coord.c (sort_coord): use swap() instead of swap_coord
- coord.h, coord.c (swap_coord): removed
- gui_util.c (save_pix_buf): use swap() instead of open-coding the swap
- kicad.c (kicad_centric): use sort_coord instead of "manually" sorting the
coordinates

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
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5967 99fdad57-331a-0410-800a-d7fa5415bdb3

- postscript.h (postscript_params): didn't declare this global variable
- postscript.c (ps_package_fullpage): if postscript_params.zoom is non-zero,
scale to this value (instead of auto-scaling)
- fped.c (usage, main): added option "-s scale" to set the scale factor for -P

- postscript.c: output all Postscript strings with ps_string, which correctly
escapes parentheses and backslashes

- 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

to also delete frames and items in other frames than the current one, and added
the corresponding regression tests.
- fpd.y, README: %del can now also delete frames
- test/del_frame: regression test for frame deletion
- fpd.y: moved all debug items into debug_item, so that they can be invoked
after defining measurements
- README: clarified that object labels aren't entirely hidden in the GUI
- delete.c (delete_references): also delete measurements referencing the frame
(test/del_frame)
- fpd.y (dbg_link_frame): described why we need base_frame in addition to
base_vec
- fpd.y, README: %del can now also reach into frames other than the current one
- delete.c (do_delete_vec): also delete references in the root frame, i.e.,
measurements (tests/del_vec)
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5947 99fdad57-331a-0410-800a-d7fa5415bdb3
through-hole pads, this could easily make them disappear into the hole. We now
draw them outside the hole.
- gui_inst.c: when showing through-hole pads, gui_draw_pad_text now places the
pad name into the largest area of the pad outside the hole
- test/frame_ref: removed redundant "with" in all titles
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5946 99fdad57-331a-0410-800a-d7fa5415bdb3
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

found in the process. Also taught the regression test system a new trick: the
path to "fped" can be passed in the environment variable FPED. E.g.,
FPED=fped.r5943 make test
- fped.c (usage, main): duplicating the -T option produces a dump to stdout
before exiting (like %dump would)
- test/Common: new command fped_dump to invoked fped with a second -T option
- test/Common: if the environment variable FPED is set, use its content to
invoke fped (default is ../fped)
- test/Common: if the environment variable CWD_PREFIX is set, prepend it to
$FPED if the latter is a relative path
- Makefile (test, tests): set CWD_PREFIX to .., so that the path given in FPED
is valid at the point of invocation
- fpd.y: revised grammar to make "package" optional
- fpd.y: measurements were syntactically allowed inside non-root frame
(test/structure)
- test/structure: test various combinations of the grammatical file structure
- test/tsort: removed all the now unnecessary "package" directives
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5944 99fdad57-331a-0410-800a-d7fa5415bdb3
the topological sort. "make test" or "make tests" invokes the regression tests,
"make valgrind" runs them under valgrind's watchful eyes.
- fped.c (usage, main): added option -T to force batch mode (for regression
testing)
- Makefile, test/Common: added regression test infrastructure
- test/tsort: test cases for the topological sort
- README: added pointer to test/tsort

- gui_style.c (gc_rim): slightly increased brightness when inactive
- 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
- layer.c (refine_layers): mirror top layers of through-hole pads
- layer.h, layer.c (mech_hole_layers): return the layer set for mechanical
layers

- overlap.c (inside, test_overlap): check for instance type
- overlap.c (inside, test_overlap): support hole instances
- README: put a pointer to the GUI description at the beginning
- README, gui.html: documented role and creation of holes
- inst.h: holes can now link to pads and vice versa
- hole.c, obj.c (instantiate): connect holes with pads and apply consistency
checks
- postscript.c: added output for holes
- icons/hole.fig: make hatched surroundings of hole look more round
git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5940 99fdad57-331a-0410-800a-d7fa5415bdb3
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

successfully referenced suddenly becomes unselectable.

- TODO: removed the entry about the frame reference procedure

documentation.
- Makefile, icons/frame_locked.fig, icons/frame_ready.fig: removed the icons of
locked and ready frames
- gui_tool.c: removed the frame tool and all the image handling associated with
it, leaving only the bits in place that are used by frame to canvas dragging
- gui_tool.h, gui_tool.c (tool_frame_update, tool_frame_deleted), gui_canvas.c
(key_press_event), gui_frame.c (popup_del_frame, select_frame): removed
the notifications of frame changes
- gui.html: removed the old clumsy frame reference procedure and described the
new way

avoid accidently dragging away bits the selected item (and confusing the
internal logic of the hover and drag system in the process), we have to make
sure nothing is selected when we enter the canvas.
- gui_canvas.c (canvas_frame_begin): make sure no instance is selected

- gui_frame_drag.c: use GTK_DEST_DEFAULT_MOTION instead of
GTK_DEST_DEFAULT_HIGHLIGHT
- gui_frame_drag.c: put meat on the frame and canvas drag and drop skeleton
- gui_frame_drag.c (setup_frame_drag, setup_canvas_drag): use GDK_ACTION_COPY
instead of GDK_ACTION_PRIVATE
- gui_frame_drag.h, gui_frame_drag.c (is_dragging_anything): new helper
function to check if we're dragging anything, without specifying what
- gui_canvas.h, gui_canvas.c: added thin interface layer between gui_frame.c
and gui_tool.c
- gui_canvas.c (enter_notify_event, leave_notify_event): return FALSE so that
other widgets can get the events, too
- gui_tool.h, gui_tool.c (tool_hover): return whether we found anything to
hover on
- gui_tool.h, gui_tool.c: added interface for dropping a frame on the canvas

tables such that items are selected on release and we can thus drag without
selecting. (From a user point of view, selecting would be fine. But selecting
may sometimes cause a change_world or similar, destroying the widget, which
upsets drag and drop.)
- gui_frame_drag.c (setup_var_drag, setup_value_drag): moved targets to file
scope
- gui_frame_drag.c (has_target, drag_var_motion, drag_value_motion): Gtk
doesn't check target compatibility for us, so we have to do this explicitly
- gui_frame_drag.c (drag_begin): don't leak the pixbuf
- gui_frame_drag.c (is_dragging, drag_end), gui_frame_drag.h: for drag vs.
activations on button release, we now can test what is being dragged. For
this, we have to explicitly clear the variable "dragging" when done.
- gui_frame_drag.c (setup_var_drag, setup_value_drag): moved common setup to
setup_drag_common
- gui_frame_drag.c (setup_frame_drag, drag_frame_motion), gui_frame_drag.h,
gui_frame.c (frame_select_event, build_frame_label): added infrastructure for
dragging frames

gui_canvas.c (motion_notify_event, make_canvas): added infrastructure for
dragging to the canvas

split logic into press and release action, so that we can drag without
implicitly selecting

a row, drag one of its value vertically.
- gui_frame.c (table_var_select_event, table_value_select_event): return FALSE

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.

confusing things.
- inst.c (rect_status_sort): wrapper for rect_status that sorts the coordinates
(min/max)
- inst.c (line_op_select, rect_op_select, meas_op_select): display the
characteristics of the diagonal of the ideal line(s), not of the bounding box
- inst.c (pad_op_select, rpad_op_select): normalize the diagonal by using
rect_status_sort instead of rect_status. This makes pads behave like silk
screen objects.

which would change the structure and remove all comments.
- fped.h, fped.c, file.c: moved declaration of save_file_name into shared

- 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

- fpd.l, fpd.y, README: added debugging directives %del, %move, %print, %dump,

- 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("").

set to the color of an active row.
- gui_frame.c (unselect_value): to detect a table, consider not only the number
of rows but also the number of columns
- gui_frame.c (unselect_value, edit_value_list): use COLOR_EXPR_* for
expressions, not COLOR_VAR_* (this has no visual effect for now, since the
colors in questions have the same value)

Measurement lines now have a fixed size, so they can't scale to invisibility.
- Makefile: don't pass CFLAGS twice when making dependencies

ps_for_all_pkg, for sharing with postscript_fullpage
- postscript.c (postscript_fullpage): print all packages

- gui_frame.c (build_table): restructured code to build tables column by column
instead of row by row
- gui_frame.c (build_table): wrap tables wider than the screen area available

- gui_util.h, gui_util.c (get_widget_width): new helper function that returns a
widget's requested width
- gui.c, gui_style.h: replace hard-coded initial pane size with constants
DEFAULT_FRAME_AREA_WIDTH and DEFAULT_FRAME_AREA_HEIGHT
- gui.c (change_world): pass the width of the left pane as a wrapping hint to
build_frames
- gui_frame.c (build_frames): subtract width of longest package template or
frame name from available width

do_build_frames

of the corresponding object but didn't change any table or loop selection to
make it active. (It did already change the frame reference.) This meant that,
upon clicking on an instance, often a different instance of the same object
would be selected. This was confusing at best.
With the below changes, table rows and loop iterations are adjusted such that
the instance that was clicked on becomes active. If the algorithm fails, fped
will print "__inst_select: tries exhausted" and fail safely. Please report if
this happens.
- obj.c (search_inst, find_inst, instantiate): added mechanism to search for
instances matching a previous instance
- obj.c (run_loops, iterate_tables): record matches in found_* elements of the
object's struct
- obj.c (reset_found, activate_found): helper functions to initialize and apply
the activation leading to the instance found
- inst.c (activate_item): added comment explaining how activate_item is
supposed to work and the fallacies of that logic
- inst.c (inst_select): added tries counter to avoid infinite recursion when
results don't converge
- inst.c (__inst_select): when selecting an instance in the same frame, adjust
tables and loops such that the instance becomes active
- inst.c: added call to find_inst after most instance creations (add_inst)
- obj.h: documented the meaning of the curr[ent]*, active*, and found* fields

- obj.c (run_loops): reset loop->curr_value to UNDEF when instantiation is done
- obj.c (generate_frame): reset frame->curr_parent to NULL when instantiation
is done
- expr.c (eval_var, eval_string_var): distinguish beteen instantiation and
editing mode, and use "active" values in the latter
- gui_frame.c (edit_var, edit_value, edit_value_list): display the value of the
variable or the active expression in the "X" field
- gui_frame.c (assignment_value_select_event, table_value_select_event,
loop_from_select_event, loop_to_select_event): pass the frame to edit_value
and edit_value_list
- expr.c (str_unit): since we may now accidently expose a wider range of
exponents, removed -2 ... 2 exponent range limitation

- gui_status.h, gui_status.c (edit_*): edit functions now accept a tooltip
- added tooltips for editable status area items
- tooltips on setup_set_type_* looked strange. Show them only for the value
field next to the type field.

This often caused accidental builds without proper dependencies.
- Makefile: include .depend also if it doesn't exist yet. This way, GNU make
will build it and all is fine.
- Makefile: use "-include" instead of "include" to avoid unnecessary nagging
- Makefile: make .depend depend on *.h and *.c, so that we catch all changes
that _might_ affect the dependencies (this is a little inefficient but better
safe than sorry)
- README: "make dep" is no longer needed
- TODO: added thoughts for more improvements

- gui_status.h: use macro to generate status_set_* delarations, just as we use
a macro for their definitions
- added tooltips for all non-editable fields in the status area

click on an anchor point of the selected object would be treated as a drag,
even if the click was very short. This created a very confusing user
experience.
- gui_canvas.c (button_release_event): if we didn't "escape" the drag radius,
don't treat the click as a drag but run the click-to-select process instead
(note: the drag visualization still flickers briefly)
- gui_canvas.c (button_release_event): to find out if we've escaped the drag
radius, just call drag_left instead of duplicating some of its code

be active, while in truth it had been reset internally.
- gui_canvas.c (button_press_event): if a click is used for selection (and not
dragging), reset the tool first

region to only cover the newly exposed area. This prevented the general
redrawing from clearing areas that still contained hovering and dragging
items. However,the paint region has no effect on reading from the drawable.
Thus when rebuilding the hover and drag stack, the still tainted image was
stored.
This issue could be solved by either introducing a separate mode where the
stack is redrawn instead of rebuilt, or by turning off double-buffering.
The former would complicate the already fickle logic of overlays, and not
having double-buffering doesn't seem to cause any ill effects.
- gui_canvas.c (make_canvas): disable double-buffering of canvas so that the
paint region is not restricted in expose events
- gui_tool.c (tool_tip): enabled canvas tooltips
