Detailed Description

A SCH_PLUGIN derivation for loading schematic files created before the new s-expression file format.

The legacy parser and formatter attempt to be compatible with the legacy file format. The original parser was very forgiving in that it would parse only part of a keyword. So "$C", "$Co", and "$Com" could be used for "$Comp" and the old parser would allow this. This parser is not that forgiving and sticks to the legacy file format document.

As with all SCH_PLUGINs there is no UI dependencies i.e. windowing calls allowed.

CreateSymbolLib()

void SCH_LEGACY_PLUGIN::CreateSymbolLib ( const wxString &  aLibraryPath, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Create a new empty symbol library at aLibraryPath.

It is an error to attempt to create an existing library or to attempt to create on a "read only" location.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several footprints.
aProperties	is an associative array that can be used to tell the library create function anything special, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR

if there is a problem finding the library, or creating it.

DeleteSymbol()

void SCH_LEGACY_PLUGIN::DeleteSymbol ( const wxString &  aLibraryPath, const wxString &  aSymbolName, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Delete the entire LIB_SYMBOL associated with aAliasName from the library aLibraryPath.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several symbols.
aSymbolName	is the name of a LIB_SYMBOL associated with it's root LIB_SYMBOL object to delete from the specified library.
aProperties	is an associative array that can be used to tell the library delete function anything special, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR

if there is a problem finding the alias or the library or deleting it.

DeleteSymbolLib()

bool SCH_LEGACY_PLUGIN::DeleteSymbolLib ( const wxString &  aLibraryPath, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Delete an existing symbol library and returns true if successful, or if library does not exist returns false, or throws an exception if library exists but is read only or cannot be deleted for some other reason.

Parameters

aLibraryPath	is a locator for the "library", usually a directory or file which will contain symbols.
aProperties	is an associative array that can be used to tell the library delete implementation function anything special, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Returns

true if library deleted or false if library did not exist.

Exceptions

IO_ERROR

if there is a problem deleting an existing library.

EnumerateSymbolLib() [1/2]

void SCH_LEGACY_PLUGIN::EnumerateSymbolLib ( wxArrayString &  aSymbolNameList, const wxString &  aLibraryPath, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Populate a list of LIB_SYMBOL alias names contained within the library aLibraryPath.

Parameters

aSymbolNameList	is an array to populate with the LIB_SYMBOL names associated with the library.
aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing one or more LIB_SYMBOL objects.
aProperties	is an associative array that can be used to tell the plugin anything needed about how to perform with respect to aLibraryPath. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR

if the library cannot be found, the part library cannot be loaded.

EnumerateSymbolLib() [2/2]

void SCH_LEGACY_PLUGIN::EnumerateSymbolLib ( std::vector< LIB_SYMBOL * > &  aSymbolList, const wxString &  aLibraryPath, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Populate a list of LIB_SYMBOL aliases contained within the library aLibraryPath.

Note

It is the responsibility of the caller to delete the returned object from the heap. Failure to do this will result in memory leaks.

Parameters

aSymbolList	is an array to populate with the LIB_SYMBOL pointers associated with the library.
aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing one or more LIB_SYMBOL objects.
aProperties	is an associative array that can be used to tell the plugin anything needed about how to perform with respect to aLibraryPath. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR

if the library cannot be found, the part library cannot be loaded.

GetError()

const wxString& SCH_LEGACY_PLUGIN::GetError ( ) const

inlineoverridevirtual

Return an error string to the caller.

This is useful for schematic loaders that can load partial schematics where throwing an exception would be problematic such as the KiCad legacy plugin.

Returns

an unformatted string containing errors if any.

GetModifyHash()

int SCH_LEGACY_PLUGIN::GetModifyHash ( ) const

overridevirtual

Return the modification hash from the library cache.

Note

This is temporary until the new s-expr file format is implement. The new file format will embed symbols instead of referencing them from the library. This function can be removed when the new file format is implemented.

Returns

the modification hash of the library cache.

IsSymbolLibWritable()

bool SCH_LEGACY_PLUGIN::IsSymbolLibWritable ( const wxString &  aLibraryPath )

overridevirtual

Return true if the library at aLibraryPath is writable.

(Often system libraries are read only because of where they are installed.)

Parameters

aLibraryPath

is a locator for the "library", usually a directory, file, or URL containing several symbols.

Exceptions

IO_ERROR

if no library at aLibraryPath exists.

Load()

SCH_SHEET * SCH_LEGACY_PLUGIN::Load ( const wxString &  aFileName, SCHEMATIC *  aSchematic, SCH_SHEET *  aAppendToMe = nullptr, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Load information from some input file format that this SCH_PLUGIN implementation knows about, into either a new SCH_SHEET or an existing one.

This may be used to load an entire new SCH_SHEET, or to augment an existing one if aAppendToMe is not NULL.

Parameters

aFileName	is the name of the file to use as input and may be foreign in nature or native in nature.
aKiway	is the KIWAY object used to access the symbol libraries loaded by the project.
aAppendToMe	is an existing SCH_SHEET to append to, but if NULL then this means "do not append, rather load anew".
aProperties	is an associative array that can be used to tell the loader how to load the file, because it can take any number of additional named arguments that the plugin is known to support. These are tuning parameters for the import or load. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Returns

the successfully loaded schematic, or the same one as aAppendToMe if aAppendToMe was not NULL, and the caller owns it.

Exceptions

IO_ERROR

if there is a problem loading, and its contents should say what went wrong, using line number and character offsets of the input file if possible.

LoadSymbol()

LIB_SYMBOL * SCH_LEGACY_PLUGIN::LoadSymbol ( const wxString &  aLibraryPath, const wxString &  aPartName, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Load a LIB_SYMBOL object having aPartName from the aLibraryPath containing a library format that this SCH_PLUGIN knows about.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several symbols.
aPartName	is the name of the LIB_SYMBOL to load.
aProperties	is an associative array that can be used to tell the loader implementation to do something special, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Returns

the part created on the heap if found caller shares it or NULL if not found.

Exceptions

IO_ERROR

if the library cannot be found or read. No exception is thrown in the case where aAliasName cannot be found.

Save()

void SCH_LEGACY_PLUGIN::Save ( const wxString &  aFileName, SCH_SHEET *  aSheet, SCHEMATIC *  aSchematic, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Write aSchematic to a storage file in a format that this SCH_PLUGIN implementation knows about, or it can be used to write a portion of aSchematic to a special kind of export file.

Parameters

aFileName	is the name of a file to save to on disk.
aSheet	is the class SCH_SHEET in memory document tree from which to extract information when writing to aFileName. The caller continues to own the SCHEMATIC, and the plugin should refrain from modifying the SCHEMATIC if possible.
aSchematic	is the SCHEMATIC object used to access any schematic-wide or project information needed to save the document.
aProperties	is an associative array that can be used to tell the saver how to save the file, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL. Set the #PropSaveCurrentSheetOnly property to only save the current sheet. Otherwise, all hierarchical sheets are saved.

Exceptions

IO_ERROR

if there is a problem saving or exporting.

SaveSymbol()

void SCH_LEGACY_PLUGIN::SaveSymbol ( const wxString &  aLibraryPath, const LIB_SYMBOL *  aSymbol, const PROPERTIES *  aProperties = nullptr  )

overridevirtual

Write aSymbol to an existing library located at aLibraryPath.

If a LIB_SYMBOL by the same name already exists or there are any conflicting alias names, the new LIB_SYMBOL will silently overwrite any existing aliases and/or part because libraries cannot have duplicate alias names. It is the responsibility of the caller to check the library for conflicts before saving.

Parameters

aLibraryPath	is a locator for the "library", usually a directory, file, or URL containing several symbols.
aSymbol	is what to store in the library. The library is refreshed and the caller must update any LIB_SYMBOL pointers that may have changed.
aProperties	is an associative array that can be used to tell the saver how to save the symbol, because it can take any number of additional named tuning arguments that the plugin is known to support. The caller continues to own this object (plugin may not delete it), and plugins should expect it to be optionally NULL.

Exceptions

IO_ERROR

SymbolLibOptions()

void SCH_PLUGIN::SymbolLibOptions ( PROPERTIES *  aListToAppendTo ) const

virtualinherited

Append supported SCH_PLUGIN options to aListToAppenTo along with internationalized descriptions.

Options are typically appended so that a derived SCH_PLUGIN can call its base class function by the same name first, thus inheriting options declared there. (Some base class options could pertain to all Symbol*() functions in all derived SCH_PLUGINs.) Note that since aListToAppendTo is a PROPERTIES object, all options will be unique and last guy wins.

Parameters

aListToAppendTo

holds a tuple of option This eventually is what shows up into the fp-lib-table "options" field, possibly combined with others. internationalized description The internationalized description is displayed in DIALOG_FP_SCH_PLUGIN_OPTIONS. It may be multi-line and be quite explanatory of the option. In the future perhaps aListToAppendTo evolves to something capable of also holding a wxValidator for the cells in said dialog: http://forums.wxwidgets.org/viewtopic.php?t=23277&p=104180. This would require a 3 column list, and introducing wx GUI knowledge to SCH_PLUGIN, which has been avoided to date.
