Display warning infobar in the board/schematic setup when no project
is loaded, since most of the settings in those dialogs are saved in
the project and not in the board/schematic file.
Fixes https://gitlab.com/kicad/code/kicad/-/issues/4868
OnBoardChanged must run after LoadProjectSettings.
Move the local overrides to PCB_EDIT_FRAME::onBoardLoaded
so that they are run after the panel is initialized.
The use of printf, wxLogDebug, and std::err/std::out causes excessive
debugging output which makes finding specific debugging messages more
difficult than it needs to be.
There is still some debugging output in test code that really needs to
be moved into a unit test.
Add debugging output section to the coding policy regarding debugging
output.
LoadProjectSettings changed to take place after the board
has been loaded so that board-specific project settings can
be applied (such as net visibility and color overrides)
- Fix file extension for new project
- Fixes for exceptions on MSW
- Fix some ASAN issues
- Allow SETTINGS_MANAGER to run headless
- Don't flag schematic as modified after schematic setup is closed
- Don't automatically unload projects when LoadProject is called
- Don't unload project if it's the same as the current one
- Make sure to properly init/de-init template field names
Per discussion on the developers list, this old system
no longer provides much value and is seen as annoying
by many users. The new save logic should prevent any
cases of file corruption on save, which was a major
reason for the backup file system existing.

Various architecture upgrades to support this.
Creating a BOARD now requires a valid PROJECT, which caused
some (mostly transparent) changes to the Python API internals.
ADDED: Project local settings file
CHANGED: Board design settings are no longer stored in PCB file
CHANGED: Net classes are no longer stored in PCB file
CHANGED: Importing board settings now reads boards, not just projects

BuildConnectivity updates the ratsnest after it completes. By compiling
the ratsnest before connectivity, we update it twice with the dirty flag
being reset after connectivity updates.
Keeping a pointer to the actual file history inside a special
file history menu led to many cases of use after free crashes,
so instead rework the actual file history to add the menu
items.
Fixes https://gitlab.com/kicad/code/kicad/issues/3741
Create an IsContentModified() function in each frame
that provides if the content has been modified, and
use that instead of always copying the checks.
Grid and ratsnest visibility are stored in the board file and should not
be changed without the user explicitly modifying them.
In the future, we'll move these settings out of the board file but we
shouldn't cause extra file-churn for flipped bits.

This allows us to make the various netlist and pcb update routines
more atomic and less reliant on carefully sequenced asynchronous
messages.
This is also a prelude to adding support for footprint testing
without a netlist.
For legacy boards, the setting is picked up from the board outline
thickness. If the board outline has mixed thicknesses, then the
max is used and a warning is displayed.

Autosave was not working correctly, partly due to different
implementations in eeschema and pcbnew and partly due to a mistaken
refactor at some point during v5 development. This unifies the expected
autosave prefix to _autosave- for both pcbnew and eeschema. It also
unifies the expected suffix for the backup files to -bak.

The standard DIM() macro was not typesafe as it happily deferred errors
to runtime that can be caught at compile time. Replacing it with a
generic C++11 constexpr allows for typecasting, comparison and compile
time error checking.
Moving pcbnew error strings that may be seen by the user to translated
strings. Strings that denote unexpected cases are moved to debug logs
as they are essentially asserts that should never be shown. The
exceptions are the messages shown when files are loaded. All unknown
items should show an error here.
The lock file code would reset the lock file every other time the same
board file was opened in Pcbnew in the stand alone mode. This created
the perfect toggle switch causing the board to be reloaded every other
time the same board was selected.
Please note that wxSingleInstanceChecker is broken on Linux and most
likely MacOS as well due to a bug in wxWidgets. On these platforms,
the already opened file is reopened rather than displaying a warning
that the file is already opened.

This also fixes a bunch of bugs where an error during save would
still close the window (rather than cancelling the close action).

Some changes (enable/disable a layer) set the dirty bit even for empty boards.
So when closing pcbnew, the dialog asking for saving the board was shown, even when no board loaded.
There are a few steps to assign correct nets to zones/track/vias:
- create a net name to pad map
- perform 2 stage netlist update (fix timestamps and then references)
- compare new net names with the previously created net map, save the
differences as a old net to new net map
- remap zones/tracks/vias using the map created in the previous step
The main advantage here is it correctly handles unnamed nets (i.e. ones
without any net labels attached), which might be changed by KiCad
netlist generator.
Fixes a bunch of errors:
- libedit and libbrowser would zoom to bounding box but centre on canvas
- libedit, libbrowser and gerbview didn’t take the scroll bars into account
- pcbnew didn’t take scroll bars into account or apply the 10% margin
- appending a board file would re-centre, but not re-zoom

The GTK+ file dialog is case sensitive however it does support regular
expressions. Most of the file dialog wildcards are lower case so only
files with the lower case extensions will show up in the file dialog.
This code adds a method to convert file extensions of any case to the
appropriate (sch -> [sS][cC][hH]) regular expression on GTK+ builds so
all file extension case combinations will show up in the file dialog.
A note to developers: make sure to add a file extension when setting
when setting the default file argument. If you do don't set an
extension, the GTK+ file dialog will happily append the regular
expression as the file extension which is surely not what you want.
There are still a few known places (mostly gerbview) where there are
some complex wildcard code that has not been converted.

- Also makes the project and file import functions filetype dependent.
- The change from IO_MGR::KICAD to IO_MGR::KICAD_SEXP removes a conflict from a compile definition for KICAD when compiling kicad/import_project.cpp
* When Pcbnew is launched in the stand alone mode with no board file command
line option, the project path is set to the current working directory. The
user may not have write access to the current working directory which would
cause the auto save to generate an error. If the user does not have write
access to the current working directory, set the path to a platform specific
temporary path that the user has write permission.
* When Pcbnew is launched in the stand alone mode with no board file command
line option, the default BOARD object has no file name. Set the file name
to "noname.kicad_pcb" to fix incorrect auto save file name and set the path
to the user's platform specific document folder.
* Delete orphaned auto save files when closing without saving due to broken
auto save file generation logic which prepended the file name with "$" rather
than "_autosave-".
* Fixes: lp:1596382
* 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.
Currently, kicad_pcb files have a (version ...) tag, but it is ignored. This
commit does the following:
1. Parse the version. If it's later than the last supported version, present an
alternative error message suggesting an upgrade if the file does not load
correctly. The version will be interpreted as an integer YYYYMMDD to suggest
a KiCad release date.
2. Accept a (version ...) tag also in kicad_mod files, but do not write them
yet. If no version tag is present in these files, assume the version to be that
of the current format version at the time of this commit.
This is meant to be merged to the 4.x stable series, and preps for KiCad 5
which will start emitting version tags also in footprints - users with what
will then be 'old stable' will not get a parse error when we introduce this for
footprints, and we can safely increment the format version later.
* File import: use case insensitive comparison to choose import plugin, from the file extension (It is not always in lower cases, especially on Windows.)
* onleftclick.cpp: fis a minor issue, which happens after switching form GAL to Legacy canvas: sometimes a board item is left selected from GAL, and creates false warning message in legacy.
The C++ preprocessor is actually not required to process "true" and "false"
correctly. This works in C if <stdbool.h> is included, because these are
then macros themselves, and resolved correctly, but C++ requires them to be
keywords, so no such macros exist, and the preprocessor can treat both as
undefined/zero.
Mostly cosmetic change, although there are compilers that choke on this.
The C++ standard specifies that classes contain themselves as members,
probably so they shadow any other definition of the same name for their own
member functions, but there is really no reason why the class name should
be duplicated here.
* Rename Eda_FileSelector to EDA_FILE_SELECTOR.
* Add optional pointer to wxString to save the most recently used path to EDA_FILE_SELECTOR.
* Rename Eda_DirectorySelector to EDA_PATH_SELECTOR.
* Replace wxGetCwd() with wxStandardPaths::GetDocumentsDir(). This fixes the windows issue
where wxGetCwd() returns the path where the executable files are located.
* Add code to handle most recently used path to EDA_BASE_FRAME.
* Fix string formatting error in kicad/files-io.cpp.
* Remove setting and restoring current working directory when launching GerbView. Setting the CWD
has no effect on the launched executable which starts with it's own CWD.
* Allow project path to be passed to GerbView when launched from KiCad.
* Note: this is a work in progress. Do not expect every path and/or file selection dialog to properly
update the most recently used path. The correct solution to this problem requires a much more
well though out solution which will not happen until after the next stable release.
Fix minor 3D viewer issues (includling change number of segments and its optimization to draw pad holes.)
Fix Bug #1439132 (track and via list on toolbar not always refresh after loading a board).
Remove useless tool in Modedit.
Rename eeschema/dialogs/dialog_sch_find.fbp to dialog_schematic_find_base.fbp, to be consistent with other dialogs.
Pcbnew run from the project manager: add menu Save Copy As..., which is the same command as Save As ... in stand alone mode, but with the constraints of a project (no cwd change, no board filename change, and keep project settings)
this option was possible only by modifying the way display options are managed.
before these changes, display options were a global DISPLAY_OPTIONS class instance.
Now each EDA_DRAW_FRAME(and derivated classes) includes its own DISPLAY_OPTIONS class instance.
As a consequence, some duplicate display option variables in these classes have been removed, because there were just duplicate variables of the DISPLAY_OPTIONS class instance.
*) When kicad.exe closes a project, close any open KIFACEs so that they cannot
get disassociated from their true PROJECT.
*) Allow loading eeschema library editor from kicad.exe
*) Allow loading pcbnew library editor from kicad.exe
*) Rename LIB_COMPONENT to LIB_PART.
*) Add class PART_LIBS, and PART_LIB.
*) Make PART_LIBS non-global, i.e. PROJECT specific.
*) Implement "data on demand" for PART_LIBS
*) Implement "data on demand" for schematic SEARCH_STACK.
*) Use RSTRINGs to retain eeschema editor's notion of last library and part being edited.
*) Get rid of library search on every SCH_COMPONENT::Draw() call, instead use
a weak pointer.
*) Remove all chdir() calls so projects don't need to be CWD.
*) Romove APPEND support from OpenProjectFiles().
*) Make OpenProjectFiles() robust, even for creating new projects.
*) Load EESCHEMA colors in the KIWAY::OnKiwayStart() rather in window open,
and save them in the .eeschema config file, not in the project file.
*) Fix bug with wxDir() while accessing protected dirs in kicad.exe
*) Consolidate template copying into PROJECT class, not in kicad.exe source.
*) Generally untangle eeschema, making its libraries not global but rather
held in the PROJECT.
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.
Removed SetCurrentClassName() (it was not used anywhere and less safe than SetCurrentClass()).
Added BOARD_DESIGN_SETTIGNS::GetDefault() to make some pieces of shorter and clearer.
Most of the changes are just adding GetDesignSettings() before every occurence of m_NetClasses.
More complex changes:
class_netclass.cpp - NETCLASS does not store the pointer to the parent BOARD anymore. Added function SetParams( BOARD_DESIGN_SETTINGS& ).
class_netclass.h - Removed GetTrackMinWidth(), GetViaMinDiameter(), GetViaMinDrill(), GetuViaMinDiameter(), GetuViaMinDrill() as they were refering to BOARD_DESIGN_SETTINGS anyway (they are not net class specific).
kicad_plugin.cpp - filters out empty nets (that are anyway not saved) when storing net class information. Previously it was done in NETCLASS::Format() function.
*) Implement a framework for "Data Load On Demand".
*) Implement FP_LIB_TABLE* PROJECT::PcbFootprintLibs(), which is the first
prototype.
This allows the project specific footprint tables to be part of the Module Editor

! 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.
* Create a generic yes/no/cancel dialog from DIALOG_EXIT.
* Make DIALOG_EXIT return wxID_YES instead of wxID_OK so it is consistent
with the standard message dialogs.
* Add missing license to confirm.h and confirm.cpp.
* Change Eeschema message dialog when loading a schematic if the current
schematic is modified to be more consistent with the exit dialog.
* Change Pcbnew message dialog when loading a board if the current board
is modified to be more consistent with the exit dialog.
* Remove some Eeschema block debug logging code left over from my last
commit.
* Add save table and set project path environment variable code to
FP_LIB_TABLE object.
* Add code to Pcbnew and CvPcb to set project path environment variable.
* Create empty footprint table in Pcbnew when new board created.
* Save current project specific footprint library table to path on file save
as or empty project path.
* Fix a bug in Pcbnew in file save function that would silently overwrite
an existing board file.
* Disable selecting the current library in the module editor when there are
no libraries defined.
* Catch exceptions and report errors when writing footprint library tables.
* Fix Boost build CMakeFile to fix bug when bootstrapping a Boost build in
MSys.
Write parser and formatter for options. Write dialog verification used before saving
FP_LIB_TABLEs, triggered from OK button in table editor.
Switch PROPERTY's value column to std::string from wxString.
Add event handler to fp lib table dialog for upcoming options dialog.
This keeps it out of the KiCad mode path, making that leaner and less confusing about
what is supported in KiCad mode. Within KiCad mode, treat quoted vs. non-quoted tokens
as the two general categories, with non-quoted having sub-categories. Eliminate
an unimplemented, unused function declaration in DSNLEXER.
Improve the output formatting of THROW_PARSE_ERROR().
This seems to me like the defacto standard for this menu command.
* Added a default filename for save as. Currently it's set to
"Unnamed file" using _() so its translatable.
* Changed the save dialog in PCBnew to use the path of the "original"
file as a base for the new file.
Pcbnew, layer manager: add option (popup menu) to always keep copper layers not visible but the active layer, even when the active layer is changed.
Usefull for multilayer ( more than 4 layers) PCBs.
* Improve MSG_PANEL_ITEM to handle message panel information.
* Create containers for passing message panel items between objects and
the message panel.
* Rename EDA_ITEM::DisplayInfo to EDA_ITEM::GetMsgPanelInfo.
* Remove all direct manipulation of EDA_DRAW_FRAME from all objects derived
from EDA_ITEM.
Because now there are 2 formats, board backup files extensions are .brd-bak or .kicad_pcb-bak instead of the old .000 extension, depending on the initial file format.
their type, by using the more abstract PLUGIN::Footprint*() functions.
This is an intermediate phase only, other changes will be necessary as library table support comes in.
Encapsulate usage of library path searching, since that will go away as library table support comes in.
Add FOOTPRINT_EDIT_FRAME::{get,set}LibPath() and FOOTPRINT_EDIT_FRAME::{get,set}LibNickName() functions
to provide this encapsulation.
* Save dialog now supports saving boards to new file format.
* Add CMake option to build s-expression file save.
* Add check to main CMakeList.txt file to make sure nanometers are
enables when the new file format is built.
* Minor tweaks to object format functions for improved output.
* Rename kicad_plugin.h/cpp to legacy_plugin.h/cpp.
* Fix compil issue about automatically created pcb_plot_params.h :
pcb_plot_params.* moved from pcbnew to common because item_io.cpp (using this file) is compiled in common.
* Removed Pcb_Frame argument from BOARD() constructor, since it precludes
having a BOARD being edited by more than one editor, it was a bad design.
And this meant removing m_PcbFrame from BOARD.
* removed BOARD::SetWindowFrame(), and BOARD::m_PcbFrame
* Removed the global BOARD_DESIGN_SETTINGS which was in class_board.cpp
* added BOARD_DESIGN_SETTINGS to the BOARD class, a full instance
* a couple dialogs now only change BOARD_DESIGN_SETTINGS when OK is pressed,
such as dialog_mask_clearance, dialog_drc, etc.
* Removed common/pcbcommon.cpp's int g_CurrentVersionPCB = 1 and replaced it
with build_version.h's #define BOARD_FILE_VERSION, although there may be a
better place for this constant.
* Made the public functions in PARAM_CFG_ARRAY be type const.
void SaveParam(..) const and void ReadParam(..) const
* PARAM_CFG_BASE now has virtual destructor since we have various way of
destroying the derived class and boost::ptr_vector must be told about this.
* Pass const PARAM_CFG_ARRAY& instead of PARAM_CFG_ARRAY so that we can use
an automatic PARAM_CFG_ARRAY which is on the stack.\
* PCB_EDIT_FRAME::GetProjectFileParameters() may no longer cache the array,
since it has to access the current BOARD and the BOARD can change.
Remember BOARD_DESIGN_SETTINGS are now in the BOARD.
* Made the m_BoundingBox member private, this was a brutally hard task,
and indicative of the lack of commitment to accessors and object oriented
design on the part of KiCad developers. We must do better.
Added BOARD::GetBoundingBox, SetBoundingBox(), ComputeBoundingBox().
* Added PCB_BASE_FRAME::GetBoardBoundingBox() which calls BOARD::ComputeBoundingBox()
* Factor test for auto save file into base frame class.
* Added auto save feature to Eeschema for saving schematics, addresses
launchpad question 173631.
* Add auto save interval control to Eeschema options dialog.
* Fix problem with subsequent auto saves in last commit.
* Factor auto save common code into base frame class so all frame windows
can take advantage of the shiny new auto save goodness.
* Use a timer instead of depending on mouse and keyboard events to trigger
an auto save.
* Check for auto save file when opening a board and ask user if they
wish to use the auto save file or the last saved board file.
* Protect all base frame public members.
* Correct all user strings and comments for the correct capitalization of
application names according to JP. They are KiCad, Pcbnew, CvPcb,
Eeschema, and GerbView.
* Add a note the the user interface policy about the correct capitalization.
* Move auto save time global variables into PCB_EDIT_FRAME object.
* Move footprint library name list global variable int PCB_EDIT_FRAME
object.
* Improve library back up and temporary file error message strings and make
them translatable.
* PCBNew string unification.
* Translate French code names and comments.
* Coding style policy and Doxygen comment fixes.
* All header files used to create the PCB common library now compile as
stand alone code. This prevents the need to define them in a specific
order to make source code compile properly. It should also now be
possible to relocate the source code to build the common PCB library
to a separate folder.
* Check user write permissions before saving project, board, and footprint
library files.
* Append read only to file name and path in title bar when the user
does not have write privileges.
* Rename class WinEDA_ModuleEditFrame to FOOTPRINT_EDIT_FRAME.
* Lot's of Doxygen comment and coding style policy fixes.
* Remove clearance and net class name read only text boxes from PCBNew
auxiliary tool bar.
* Display full net class information in message panel when an object that
supports net classes is selected.
* Move coordinate string conversion function to EDA_DRAW_FRAME object and
made it more versatile.
* Refresh message panel text when units change.
* Fix grid select box update bug on context menu.
* Fix via size and track width select box update bugs.
* Fix layer pair indicator button update bug.
* Fix auto track width tool bar control enable bug.
* Fix via size and track width select status bug in context menu.
* Fix layer select box and layer control widget select bug when current
layer is removed.
* Add virtual function to notify objects derived from EDA_DRAW_FRAME that
the units setting has changed.
* Coding policy class naming fixes.
* Make EDA_DRAW_FRAME current tool ID member variable private.
* Added global no tool selected ID to replace application specific no
tool selected IDs.
* Change SetToolID to prevent setting the tool ID to anything less than
the new global no tool selected ID and assert on debug builds.
* Change command and update user interface command event handlers to use
new global no tool selected ID.
* Fixed schematic library editor add pin hot key handler.
* Old control state handling code completely removed in all applications.
* Factor common control state handlers into EDA_DRAW_FRAME.
* Replaced EDA_ITEM test for newness with IsNew() method.
* Factor vertical right toolbar command handlers out of giant edit command
switch statement in EESchema and PCBNew.
* Rename all member variables and methods that reference the cross hair
code in draw panel object from cursor to cross hair to eliminate confusion
between the two concepts.
* Rename cursor capture call backs in draw panel object to improve code
readability.
* Create helper class for turning off the cross hair while drawing.
* Remove redundant block clear code.
* Remove redundant mouse capture call back reset code when end capture
call back is called.
* Remove unused function definitions in base draw frame object.
* Lots of minor coding policy and doxygen comment fixes.
* Fix rendering bug in GerbView caused by wxDC scaling change caused by
setting the wxDC clipping region.
* Eliminate the need to have optional background erasing as the change
above fixed that problem as well.
* Default cursor handling improvements.
