Sub-libraries allow a single-level hierarchy inside a symbol library.
This is useful for database libraries and for supporting other EDA library types where a
single file can contain multiple logical groupings of symbols.
Allows placing parts from an external database that reference symbols from another loaded library.
Includes:
- nanodbc wrapper
- database schematic library plugin
- basic tests

Set up a new lineage for SCH_ITEMS to get back to the SCHEMATIC
they live on: Items will all be parented to the SCH_SCREEN that
they are added to, and each SCH_SCREEN will point back to the
SCHEMATIC that it is part of. Note that this hierarchy is not
the same as the actual schematic hierarchy, which continues to
be managed through SCH_SHEETs and SCH_SHEET_PATHS.
There has been a long standing (since the beginning of the project?)
issue with sharing schematics between projects. It has been somewhat
supported for complex hierarchies (a sheet shared multiple times in a
single design) but it has not been well supported for simple hierarchies
(the symbol references cannot be changed in the shared schematic). This
issue has been resolved by moving all of the symbol instance sheet paths
from the symbol definitions in the all of the project files and save all
symbol path instances in the root sheet. This ensures that orphaned
symbol instance paths do not accumulate in shared schematic files and
that designs that reuse schematic in simple hierarchies can how have
different references. It also allows the root schematic from one project
to be uses as a sub-sheet in another project.
When legacy schematics are loaded, all sheet and symbol UUIDs are
converted from time stamps to true UUIDs. This is done to ensure there
are no sheet path instance clashes between projects. That being said,
there are no checks for this. It is assumed that the probability of
UUID clashes is so low that it doesn't make sense to test for them.
Please note that the symbol cache is not embedded in the schematic file
to allow for round robin testing with the existing file format. Once
the parser round robin testing is complete, the symbol cache will be
embedded in the schematic file.
This implements all existing symbol library object support and the ability
to save and load symbol library files between file formats for round robin
testing.
CHANGES: Symbol library file format has been converted to s-expressions.
Add support code for picking apart symbols at some future junction that
will allow full inheritance conversion of existing symbol libraries. For
now, symbols arranged by unit and body style numbers are nested for round
robin testing of symbol libraries once the parser is complete.
This change completely removes the LIB_ALIAS design pattern an replaces
it by allowing LIB_PART objects to inherit from other LIB_PART objects.
The initial implementation only allows for single inheritance and only
supports the mandatory fields in the derived part because that is all
that the current symbol library file format will support. Once the new
file format is implemented and saving to the old file format is deprecated,
more complex inheritance will be added. The LIB_ALIAS information saved
in the document files was move into the LIB_PART object. This change
impacts virtually every part of the schematic and symbol library editor
code so this commit message is woefully incomplete.
REMOVE: Removed the symbol aliases concept from the schematic and symbol
editors and the symbol viewer.
NEW: Replace the symbol alias concept with simple inheritance that allows
a library symbol to be derived from another library symbol.
With the implementation of the legacy schematic plugin, any I/O error
when parsing the schematics would prevent the entire schematic from
being loaded. This change restores (somewhat) the previous behavior
where as long as the root schematic is loaded properly, then all of
the remaining sub-sheet will attempt to load.
Add GetError() method the SCH_PLUGIN object to allow for partial
schematic loading.
Check the error message contents when no exception was caught to warn
the user of any accumulated errors.

Remove the placeholders for the upcoming s-expression schematic and
symbol library file format plugin type. The lack of a valid plugin
implementation was causing an undefined plugin type string in the
plugin type selection cell when new rows were added to the table.

- 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
- !! Eeschema uses Eagle plugin for loading schematics (i.e. it does not
use KiCad format anymore)
- Fixed build errors
- Fixed a few crashes
- Code formatting
Add SCH_PLUGIN object to PART_LIB object.
Convert all PART_LIB I/O to use SCH_PLUGIN.
Remove library caching from PART_LIB and use caching provided by SCH_PLUGIN.
Add support to use PROPERTIES for buffering and document file write control
instead of adding code the SCH_PLUGIN object in the SCH_LEGACY_PLUGIN that
will not be required when the new file formats are implemented.
Add buffering to SCH_LEGACY_PLUGIN to prevent cache from writing file on
every change to library. This is to prevent the cache library from being
written every time a new symbol is added.
Add option to not save library document file when saving library. This is
primarily used by the cache library write code.
Move symbol library write code out of LIB_PART and into SCH_LEGACY_PLUGIN.
Add exception handling where LIB_PART caught the exception and returned
an error status.
Remove KICAD_SCH_IO_MANAGER build option as it is no longer optional.
Make LIB_PART copy constructor take a const LIB_PART reference.
Add SaveSymbol to legacy symbol library plugin.
Add removeAlias to legacy symbol library cache.
Add AddSymbol to legacy symbol library cache.
* Write SCH_LEGACY_PLUGIN_CACHE object for handling the legacy symbol library
file format.
* Write legacy symbol library file parser.
* Write code to transfer cache to PART_LIB object so existing library save
code can be used for round trip testing. This is temporary until Eeschema
is updated to use the plugin for library management rather than PART_LIB.
* Add LIB_XXXX object helper functions where there was no way to set the member
variables of an object.
* Give the cache object friend status to some object where there are incredibly
byzantine ways of setting text in LIB_XXXX objects.
* Add SCH_PLUGIN::Save() for current file format and code for saving all
SCH_XXX objects.
* Add function to SCH_FIELD to get the position of the field in the component
not the position added to the component position which is what GetPosition()
does. This was required because saving the component field expects position
of the field sans the position of the component.
* Remove public members from BITMAP_BASE object and fix all associated
code.
* Fix the never ending coding policy violations found making these changes.
* 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.
