This can be used for "advanced" options which are for developers
to use for feature-flags and other configuration. Run time config
has some advantages over preprocessor defines:
* Can be changed without recompilation
* Sensitive to XDG_CONFIG_DIR, so flipping configs is easy
* Better compiler coverage (less conditionally compiled code means
less chance to break a different configuration). Also better
analysis coverage.
* Type safe config params
* Centralised documentation: it's in doxygen, in one place
No advanced config should be required by a general users. If a general
user does use one of these configs, it's probably because:
* There is a bug and one of these configs is a workaround
* A config in here is generally useful and should be moved into the
relevant application config and given UI.
For now, the config is read-only, and is read from the
"kicad_advanced" config file in the normal config dir.
The libeval grammar can now be rebuilt with "make libeval_grammar".
This is only possible when lemon is installed.
Also a couple of modifications to the lemon grammar to
account for external changes since the grammer was last generated.
Also move the grammar defines into grammar.h - this is how
Lemon produces them, and by manually copying into the target .cpp,
it make automated regeneration impossible.
This is done to avoid a big chunk of conditionally-compiled code
in the middle of the event function.
Also separates the zoom logic from the WX_VIEW_CONTROLS object
and isolates it in a separate class behind a clearer interface.
Add some simple tests for sane steps on GTK+3-sized scroll
steps.
This avoids having to manually specify include/legacy_gal
in and legacy GAL targets, and harominizes with legacy_wx.
This also means .cpp files in common/legacy_gal do not
need to specify the legacy_gal subdirectory, so they
will continue to work as needed when legacy_wx is removed.
CAIRO_PRINT_CTX provides a Cairo context created from wxPrintDC.
It allows one to prepare printouts using the Cairo library and
let wxWidgets handle the rest.
The connectivity files were unwieldy. This separates them logically
into data, algo and items where the items classes are those that hold,
surprise, surprise, the items, lists and clusters.
Note: it's only the renderer that is changed from wxDC to GAL. Tools stay the same, consider this a temporary hack.
This commit splits the EDA_DRAW_FRAME, EDA_DRAW_PANEL and BLOCK_SELECTOR classes into two variants, each independently compiled into a static library.
- "legacy_wx" for PCBnew/Gerbview - wxDC-based legacy canvas. We have full GAL support there anyway so it makes no sense to introduce GAL rendering API to the legacy tools.
- "legacy_gal" for EEschema and the rest - GAL-based legacy canvas, using legacy tools but with a GAL renderer.
Such split ensures only a small part of the common library and eeschema is affected, without messing around with already GALified tools.
The commit also removes some header dependencies on class_drawpanel.h
There are lot of places where constants are used in the KiCad UI
as "magic numbers". The most common one is "5", used in many
wxFormBuilder and manual UI constructions as the margin.
This commit provides a place for all UI to look up shared
constants and other functions, to help create a consistent UI using
functions that provide meaning and intent to these magic numbers.
This is in preparation for making this widget optionally read-only.
Major changes:
* Construct panel in code, not with wxFormBuilder. This make's it
easier to conditionally construct elements that won't be used
in a read-only mode (e.g. the buttons).
* Use a generic "button row panel" widget for the buttons, as the
sizing and layout logic is reusable in nearly all dialogs, and
it's simplifies layout in the higher-level dialog widget. This
widget is one example of many possible "reuable widgets".
This puts generic logic for KiCad environment vars in
one place.
Also updates the DIALOG_CONFIGURE_PATHS help to document
the new KICAD_USER_TEMPLATE_DIR and KICAD_TEMPLATE_DIR.
This separates the "ground truth" store of hotkeys from what is shown
in the dialog. This will allow us to filter the displayed hotkeys
while keeping the same underlying data structures.
Now, the UI data items interact with an intermediate set of data, which
represents the "original" hotkey data, and the "changed" data. The
ultimate aim here is to allow UI elements to come and go, but the
hotkeys that are "in-edit" are preserved.
This also allows us to abstract some bookkeeping complexity
out of the WIDGET_HOTKEY_LIST class into a separate non-GUI
class.
Also fixes a bug where nets wouldn't get changed because the
pads weren't changed and so the pad nets would propagate and
wipe out the changed nets on the tracks.
Also includes warning dialogs that pad nets will be changed if the
track nets are.

Primary change is to replace most control/window borders with
AUI pane borders. We implement our own AUI border drawing
routine which avoids the ugly one-pixel white frames around
dark canvasses.
Also increases the signal-to-noise ratio of all the pane
creation code in the various frames.
wxWidgets offers two dialog types: wxFileDialog and wxDirDialog, one
to select files, the other to select directories, but neither of them
handles both. DIALOG_FILE_DIR_PICKER fills that gap.
The opencascade patch intrusively checked against libraries but broke
some build scripts. This restores the default cmake OCE behavior that was
changed by 2bab30d9a and makes the OpenCascade search truly secondary.
This is meant as a stopgap for 5.0, with plans to add proper scaled
icons in the 6.0 cycle. A function KiScaledBitmap() is added, which
works like KiBitmap() except it scales the bitmap according to the
calling window's font size. Controls have been added to all the main
applications to let the user select scaling manually (these were omitted
from smaller apps that didn't already have a place to put them).
In addition, in eeschema only, the pixel height of the system font is
shown in the options dialog for diagnostics. This is only for collecting
feedback before 5.0 release from users with different displays and will
be removed.
Moved the code handling text overbars to a single function
(ProcessOverbars()) to replace similar pieces of code trying to do the
same thing.

This target seems to only create empty makefiles, tested on linux. And I
can not find any references to it in any of the current CMakeLists. Lets
remove it.
- renamed connectivity.[h|cpp] to connectivity_data [.h|.cpp] so that the file name matches the main class name.
- GetNetItems() now returns a vector instead of a list
- support for background color setting
- removed several global config settings (such as g_Drc_On)
- wrapped most of global config settings in PCB_GENERAL_SETTINGS class
- reorganized PCB general options dialog to clearly mark which options concern only the legacy canvas
- new GAL feature for legacy users: double-click (or E) to change track width available as an option.

In order to get rid of another boost dependency, this also changes
the parsing of the XML from Boost.PropertyTree to wxXml.
To replace boost::optional, an OPTIONAL_XML_ATTRIBUTE class has
been implemented. This could be replaced with std::optional when
C++17 is ready.
- DIALOG_CHOOSE_COMPONENT has footprint select widget
- FOOTPRINT_SELECT_WIDGET
- FOOTPRINT_CHOICE widget (customized wxComboCtrl)
- FOOTPRINT_FILTER class
- FOOTPRINT_INFO rework:
- FOOTPRINT_ASYNC_LOADER to load without freezing UI
- Rewrite loader threads as queue-driven thread pool
- Make FOOTPRINT_INFO available via kiway
- FP_LIB_TABLE::PrefetchLib
- Access to global fp-lib-table via kiway
- SYNC_QUEUE threadsafe queue template
- Remove KICAD_FOOTPRINT_SELECTOR build option
The executable name constants are only used by two files, they do not
have to be in common.h.
Also converted to const wxString for better type-safety and removed
old-style wxT macros.
The zone creation in DRAWING_TOOL was a complex event loop whici
simultaneously managed the event handling, construction of the preview
polygon and the creation and commiting of the zone, all in the same
scope. This has been broken into several pieces:
* POLYGON_ITEM preview item, used to preview the polygon in progress
* POLYGON_GEOM_MANAGER is a class that collects points from user input
and used them to describe a polygon's geometry, including calculation
of 45-degree constrained leader lines
* ZONE_CREATE_HELPER is a class which deals with creating zones based on
geometry from a geometry manager and parameters from the DRAWING_TOOL
* The (much simpler) event loop in DRAWING_TOOL drives the
POLYGON_GEOM_MANAGER. With a minor refactor, this loop can be reused
in future for other polygonal tools if wanted.
The polygon preview now has a translucent fill which makes it easier to
visualise the zone.
This also adds the Close Zone Outline and Delete Last Corner actions as
part of the new event loop.

This adds the microwave tools to GAL in Pcbnew as a new tool:
MICROWAVE_TOOL.
Some new preview items are introduced to support this:
* TWO_POINT_GEOM_MANAGER for managing construction of two-point
geometries, such as that used to construct the inductor.
* CENTRELINE_RECT_ITEM a preview item to draw ractangle with a given
aspect ratio along a line (specified using a TWO_POINT_GEOM_MANAGER)
PCB_TOOL gets a generic event loops which should be useful for more
than just microwave tools:
* doInteractiveItemPlacement() - handles event loops that wait for a
click, create an item on click and then allow moving it
around/flipping, etc.

This adds a richer overlay to the arc-by-three-points tool in Pcbnew,
including more guide-lines and a live display of radius and angle.
Also included is ability to go back to the previous step (if setting end
angle, you can go back to setting start point, etc) using Backspace, and
Ctrl snaps the start/end angles to 45 degree multiples.
This adds new classes
* MULTISTEP_GEOM_MANAGER: represents a generic "geometry manager" that
builds up some geometrical construction based on a sequence of points.
Used by:
* ARC_GEOM_MANAGER: handles the logical flow of constructing an
arc by centre-point, set radius, set angle. This moves the logic out
of the Pcbnew DRAWING_TOOL event loop in drawArc().
* ARC_ASSISTANT: graphical overlay to communicate current arc shape to
the user during the drawing process
The primary motivation here is to allow other GAL canvas users (eg
Modedit, and soon Gerbview) to be able to easily modify GAL canvas
options.
For now, this doesn't change the display properties dialog in
appearance, but if more GAL options are added, it might need a bit of
tweak and maybe tabs or similar, like Eeschema preferences.
- Pull out compound widget bits into FOOTPRINT_PREVIEW_WIDGET
- Move all pcbnew-specific bits *inside* pcbnew; implementation should
be private for users
- Make a few class members and inner types private
This allows to measure between features on a PCB. It uses a preview
EDA_ITEM in common, but due to the use of the IDs, it's currently
Pcbnew/Modedit only.
This also adds several "utils" for graphical functons useful when
drawing preview items on GAL canvases.

This simplifies the (already simple) SELECTION_AREA class. It is also
moved into KIGFX::PREVIEW and put in the common library, where it can be
reused by other GAL-aware tools (not just in Pcbnew) in future.
This introduces SIMPLE_OVERLAT_ITEM, which is an abstract EDA_ITEM,
designed for use as an overlay for assisting interactive tools.
The item is drawn only on the GP_OVERLAY layer, and sets the fill,
stroke and line properties before calling a virtual function to draw the
shape, which will depend on the implementaiton of the derived class.
The motivation here is to simplify and unify basic overlays used when
in interactive tools. It is not designed to be the base class of all
possible overlays - more complex ones would be more clearly represented
as their own derivative of EDA_ITEM.
Applications of this class can include: zoom/select rectangles, zone
polygon previews, geometric shape helpers, and so on.
The introduces INDICATOR_ICON, which is a very simple class holding a
bitmap that can toggle on or off.
The ICON_PROVIDER class then provides icons to INDICATOR_ICONS, which
means the class can be used for more than just row indicators.
A default row icon provider is also provided for use in the standard row
selector.
This introduces COLOR_SWATCH, which is a reusable
widget that shows a color swatch and can invoke the colour picker
when duble/middle clicked.
It uses it's own wxCommandEvent to signal the change.
This makes the layer widget simpler internally, and also allows other
code to show identical swatches if needed.
SELECTION now holds EDA_ITEMs not BOARD_ITEMs so various places had to
change to casting the selected items to BOARD_ITEMs.
Fixed compilation warnings on clang (Tom)
Some grid/zoom tools are left in PCBNEW_CONTROL because they currently
depend on Pcbnew-specific class members. Once refactoring is done to
make it possible to use all zoom and grid controls outside of pcbnew,
these last tools can be moved to common to match their ACTIONs.
This class, INCREMENTAL_TEXT_CTRL, is used to provide a frameworks for
classes that want to control a text control that can be incremented
according to some scheme.
Also provided is a wxWidgets implementation with spin buttons for
control, as well as mousewheel support.
This commit brings several changes:
- Add a footprint preview pane to the eeschema component selector
- Upgrade component list to wxTreeListCtrl
- Factor out wxTreeListCtrl subclass TWO_COLUMN_TREE_LIST which
patches a column size bug
- Linkify datasheet URL in info pane
Define empty string variable KICAD_BRANCH_NAME that can be used as an
optional version string element. When git is used to build the version
string, this variable is set to the git branch name. It can also be
defined at configuration time as an optional string appended to the
$KICAD_VERSION variable.
Define empty string variable KICAD_VERSION_EXTRA that can be set by
the user at configuration.
The variables KICAD_BRANCH_NAME and KICAD_VERSION_EXTRA are only
appended to KICAD_VERSION if they are set. Otherwise, only KICAD_VERSION
is uses as the version string.
Update the developer building from source document to reflect the changes.
Rename FPID to LIB_ID as is now used as a generic library identifier and
is no longer specific to footprints.
Remove all mention of footprint from the new LIB_ID doxygen comments and
code.
Rename files fpid.h and fpid.cpp to lib_id.h and lib_id.cpp.
Rename fp_lib_table.keywords file to lib_table.keywords and adjust CMake
build dependencies accordingly.
Update all source files effected by the code and file name changes.
Update .gitignore for file name changes.
Create SYM_LIB_TABLE and SYMBOL_LIB_TABLE_ROW objects derived from LIB_TABLE
and LIB_TABLE_ROW respectively for supporting symbol library tables.
Add FPID member to LIB_PART for associating a symbol to a specific library
nickname. Please note, this is not used in any way at this time and will be
implemented when the symbol library table is actually implemented.
Add sym_lib_table keyword to keywords file. This is a temporary measure
until a more elegant method for parsing and formatting library tables can
be implemented.
Build FPID support in the common library instead of the pcbcommon library
for use in Eeschema.
*) Extend SWIG support deeper into the BOARD class.
*) Move swig *.i files into a directory identified for SWIG, in preparation
for a parallel universe involving Phoenix's SIP.
*) Move swig files which will be common to both eeschema and pcbnew into
common/swig.
*) Sketch out a "common" python module, and plan on dovetailing that into a
libkicad_shared.{dll,so}
*) Add common/swig/ki_exceptions.i and define a macro HANDLE_EXCEPTIONS()
which is to be applied to any function which needs C++ to python
exception translation.
*) Move the test for SWIG tool into top level CMakeLists.txt file for use
in all python modules beyond pcbnew, i.e. eeschema and common.
*) Add SWIG_MODULE_pcbnew_EXTRA_DEPS which generates a better Makefile, one
which rebuilds the swig generated *.cxx file when one of its dependencies
change.
*) Re-architect the board.i file so that it can be split into multiple *.i
files easily.
*) Make some KIWAY from python progress, in preparation for Modular KiCad
phase III.
This option is not yet activated because the net attributes are not yet fully fixed by Ucamco, in Gerber file format specifications.
(To activate it, see dialog_plot.cpp, line 43)
* Split and rewrite the preview window and canvas.
* Create a new class for handling the board information.
* Adds new render targets: openGL, legacy, and ray tracing.
* Render targets take full advantage of the new 3D plugins system and 3D cache
for a fast 3D model loading.
* Faster board loading.
* New OpenGL render is faster than the old one.
* New ray tracing render target with a post processing shader.
* Use of new 3D plugins (WRL, X3D, STEP and IGES) and 3D model caching.
* Preview of 3D model while browsing the file name.
* 3D preview of the footprint while adding / align 3D shapes.
* Render of 3D models according to attributes: Normal, Normal+Insert, Virtual.
* Pivot rotation centered in one point over the PCB board.
* Shortcuts keys improved for XYZ orientation..
* Animated camera.
* Factor out PROPERTIES object from the PCB plugin code and move it into
common so it can be used by both the Pcbnew and Eeschema plugins.
* Add schematic I/O plugin manager for loading and saving schematic and
component library files.
* Add initial attempt at a parser for current schematic file format. This
parser will be infinitely more strict than the current parser which is very
forgiving in what it parses.
* Make minor changes to the base bitmap class to support the new parser.
* Add find root sheet support to sheet object to allow fetching the root
sheet from any sheet in the stack.
* remove duplicate code between draw functions and STROKE_FONT used in GAL. Use only STROKE_FONT methods in draw, plot and test DRC function for texts. It remove slightly different shapes between GAL and other calculations.
* fix incorrect bounding box for texts with overbar. Especially noticeable for texts with overbar inside a copper zone in Pcbnew.
* fix a few minor other bugs related to graphic texts.
* Dick Hollenbeck also contributed commit r6440. I inadvertently forgot to set
the Bazaar author tag before I committed it. My apologies.
* Switch to static linking of libcurl and on linux and windows and also
statically link in only required portions of openssl.
* Add the required thread locks which openssl needs.
* Remove the get curl version call from BASEFRAME since it pulls in curl and
openssl into every derived wxFrame class link image.
* Remove curl function from PGM_BASE, switch to atexit() instead. Anything in
PGM_BASE made the singletops bigger.
* Tested on Linux, Windows, and OSX.
* Prevent libcurl from inadvertently being initialized twice.
* Dynamically load libcurl only when required.
* Reduce the number of worker threads when loading footprint libraries to
prevent issues with the GitHub plugin.
* Create base class EDA_PATTERN_MATCH to hand multiple pattern matching methods.
* Create classes for regular expression and wildcard pattern matching.
* Add new pattern matching semantics to component select dialog.
* Thanks to Henner Zellar <h.zeller@acm.org> for improvments to the original patch.
* Use CMake add_custom_target() to run WriteVersionHeader.cmake as a command.
* Modify WriteVersionHeader.cmake to be run as a command instead of a macro.
* Add version header creation as a CMake common library build dependency.
* Add cached CMake variable KICAD_BUILD_VERSION when build version is defined during
configuration.
* Create new dialog to edit environment variables.
* Add helper class ENV_VAR_ITEM to manage environment variable values and
if they were defined externally.
* A path configuration dialog access to KiCad, CvPcb, Pcbnew, and Footprint Editor
window menus.
* Add validator for environment variables.
* Make all files generated by make_lexer() dependencies of thier respective build targets.
* Make building Boost a dependency for all libraries.
* Remove duplicate make_lexer() call for Specctra lexer files.
Refactor hotkey editor to use tab control instead of one giant list.
Each tab is a separate hotkey section.
Modify EDA_HOTKEY_CONFIG to change the m_Comment member to m_Title for a new purpose.
We want a pretty title in the hotkey editor. We use m_Title for the key export comment which
still conveys the purpose just as easily.
Refactored usage of wxGrid into wxListCtrl which allows capturing navigation characters
and also works better (single selection is built in).
Add hotkey overwrite prompts that are paired with "Common" section. It will check if a hotkey
overlaps with the proper sections. i.e. Common with the all other sections; or Section 1 with just Common.
Right-click menu removed due to wxListCtrl being able to catch the special keys properly.
2) Change from legacy Cu stack to counting down from top=(F_Cu or 0).
The old Cu stack required knowing the count of Cu layers to make
sense of the layer number when converting to many exported file types.
The new Cu stack is more commonly used, although ours still gives
B_Cu a fixed number.
3) Introduce class LSET and enum LAYER_ID.
4) Change *.kicad_pcb file format version to 4 from 3.
5) Change fixed names Inner1_Cu-Inner14_Cu to In1_Cu-In30_Cu and their
meanings are typically flipped.
6) Moved the #define LAYER_N_* stuff into legacy_plugin.cpp where they
can die a quiet death, and switch to enum LAYER_ID symbols throughout.
7) Removed the LEGACY_PLUGIN::Save() and FootprintSave() functions.
You will need to convert to the format immediately, *.kicad_pcb and
*.kicad_mod (=pretty) since legacy format was never going to know
about 32 Cu layers and additional technical layers and the reversed Cu
stack.
Do not pay attention to add/remove files - it seems there may be a bug in git-bzr-ng plugin. I have checked them, they stayed exactly the same as before.
if it is running under single_top.cpp or under a project manager.
*) Test Kiface().IsSingle() when adding menus, some operations are not permitted
when running under a project manager and the KIWAY_PLAYER is pegged to a
specific project.
*) Implemented KIWAY::KiFACE() so it loads *.kiface files. They still have to be
in the same directory as the main *.exe launcher, so this presents some difficulty
when the binaries are not yet installed but rather the *.kiface files are still
in their original build directories. For today, I simply copied _pcbnew.kiface
to build/kicad/.
*) Add a test case to kicad/mainframe.cpp just to get an early peek at loading
_pcbnew.kiface under the C++ project manager. Got that working for one
specific invocation just for proof of concept. Surprise, it works.
! The initial testing of this commit should be done using a Debug build so that
all the wxASSERT()s are enabled. Also, be sure and keep enabled the
USE_KIWAY_DLLs option. The tree won't likely build without it. Turning it
off is senseless anyways. If you want stable code, go back to a prior version,
the one tagged with "stable".
* Relocate all functionality out of the wxApp derivative into more finely
targeted purposes:
a) DLL/DSO specific
b) PROJECT specific
c) EXE or process specific
d) configuration file specific data
e) configuration file manipulations functions.
All of this functionality was blended into an extremely large wxApp derivative
and that was incompatible with the desire to support multiple concurrently
loaded DLL/DSO's ("KIFACE")s and multiple concurrently open projects.
An amazing amount of organization come from simply sorting each bit of
functionality into the proper box.
* Switch to wxConfigBase from wxConfig everywhere except instantiation.
* Add classes KIWAY, KIFACE, KIFACE_I, SEARCH_STACK, PGM_BASE, PGM_KICAD,
PGM_SINGLE_TOP,
* Remove "Return" prefix on many function names.
* Remove obvious comments from CMakeLists.txt files, and from else() and endif()s.
* Fix building boost for use in a DSO on linux.
* Remove some of the assumptions in the CMakeLists.txt files that windows had
to be the host platform when building windows binaries.
* Reduce the number of wxStrings being constructed at program load time via
static construction.
* Pass wxConfigBase* to all SaveSettings() and LoadSettings() functions so that
these functions are useful even when the wxConfigBase comes from another
source, as is the case in the KICAD_MANAGER_FRAME.
* Move the setting of the KIPRJMOD environment variable into class PROJECT,
so that it can be moved into a project variable soon, and out of FP_LIB_TABLE.
* Add the KIWAY_PLAYER which is associated with a particular PROJECT, and all
its child wxFrames and wxDialogs now have a Kiway() member function which
returns a KIWAY& that that window tree branch is in support of. This is like
wxWindows DNA in that child windows get this member with proper value at time
of construction.
* Anticipate some of the needs for milestones B) and C) and make code
adjustments now in an effort to reduce work in those milestones.
* No testing has been done for python scripting, since milestone C) has that
being largely reworked and re-thought-out.
To use multiple working threads. This entailed adding KiCad typedefs:
*) Add typedefs for MUTEX and MUTLOCK which mask the actual choices for the project.
*) Add FOOTPRINT_LIST::DisplayErrors( wxWindow* ) which is a single strategy for
showing aggregated load errors. Although what's there is only scaffolding
and needs a volunteer who knows HTML pretty well.
*) Ensure all callers of ReadFootprintFiles() use the new DisplayErrors() function.
*) Push utf8.cpp and utf8.h into common library for open use.
* Add code to CvPcb to handle assigning component footprints from the
footprint library table instead of the search path method.
* Add code to CvPcb to allow editing of the footprint library table.
* CvPcb footprint and component panes display fully qualified FPID names.
* Make CvPcb library pane display footprint library table nicknames instead
of library file names.
* Add code to FP_LIB_TABLE object to test the paths in the table against the
list of libraries loaded from the project file.
* Add code to FP_LIB_TABLE to convert assigned footprints in a NETLIST from
legacy format to footprint library table format.
* Split out COMPONENT_NET, COMPONENT, and NETLIST objects from netlist_reader
files and create new pcb_netlist files.
* Fix minor wxListView scroll bar sizing issues.
* Add new token and code to save and load FPID nickname in board file.
* Add new token and code to save and load FPID nickname in s-expression net
list file.
* Add WX_STRING_REPORT object to dump strings to a wxString object.
