Detailed Description

A collection of SYMBOL_LIB objects.

It extends from PROJECT::_ELEM so it can be hung in the PROJECT. It does not use any UI calls, but rather simply throws an IO_ERROR when there is a problem.

Allocate and adds a symbol library to the library list.

Parameters

aFileName

is the file name object of symbol library.

Exceptions

IO_ERROR

if there's any problem loading.

 SYMBOL_LIB* lib;
 
 wxFileName fn = aFileName;
 // Don't reload the library if it is already loaded.

		SYMBOL_LIBS::iterator &	aIterator
	)

Insert a symbol library into the library list.

Parameters

aFileName	is the file name object of symbol library.
aIterator	is an iterator to insert library in front of.

Returns

the new SYMBOL_LIB, which remains owned by this SYMBOL_LIBS container.

Exceptions

IO_ERROR

if there's any problem loading.

CacheName()

const wxString SYMBOL_LIBS::CacheName ( const wxString &  aFullProjectFilename )

static

Return the name of the cache library after potentially fixing it from an older naming scheme.

That is, the old file is renamed if needed.

Parameters

aFullProjectFilename

is the *.pro filename with absolute path.

Definition at line 437 of file symbol_library.cpp.

{
 wxFileName name = aFullProjectFilename;
 
 name.SetName( name.GetName() + "-cache" );
 name.SetExt( LegacySymbolLibFileExtension );
 
 if( name.FileExists() )
 return name.GetFullPath();
 
 return wxEmptyString;
}

FindLibrary()

SYMBOL_LIB * SYMBOL_LIBS::FindLibrary

(

const wxString &

aName

)

Find a symbol library by aName.

Parameters

aName

is the library file name without path or extension to find.

Returns

the symbol library if found, otherwise NULL.

Definition at line 307 of file symbol_library.cpp.

{
 for( SYMBOL_LIBS::iterator it = begin(); it!=end(); ++it )

FindLibraryNearEntries()

void SYMBOL_LIBS::FindLibraryNearEntries	(	std::vector< LIB_SYMBOL * > &	aCandidates,
		const wxString &	aEntryName,
		const wxString &	aLibraryName = wxEmptyString
	)

Search all libraries in the list for a LIB_SYMBOL using a case insensitive comparison.

Helper function used in dialog to find all candidates. During a long time, eeschema was using a case insensitive search. Therefore, for old schematics (<= 2013), or libs, for some symbols, the chip name (name of alias in lib) can be broken. This function can be used to display a list of candidates, in symbol properties dialog.

Parameters

aEntryName	is the name of entries to search for (case insensitive).
aLibraryName	is the name of the library to search.
aCandidates	is a std::vector to store candidates.

Definition at line 386 of file symbol_library.cpp.

 for( SYMBOL_LIB& lib : *this )
 {
 if( !aLibraryName.IsEmpty() && lib.GetName() != aLibraryName )

 continue;
 
 for( size_t i = 0; i < partNames.size(); i++ )
 {
 if( partNames[i].CmpNoCase( aEntryName ) == 0 )
 aCandidates.push_back( lib.FindSymbol( partNames[i] ) );
 }
 }

FindLibSymbol()

LIB_SYMBOL * SYMBOL_LIBS::FindLibSymbol	(	const LIB_ID &	aLibId,
		const wxString &	aLibraryName = wxEmptyString
	)

Search all libraries in the list for a symbol.

A symbol object will always be returned. If the entry found is an alias. The root symbol will be found and returned.

Parameters

aLibId	is the LIB_ID of the symbol to search for.
aLibraryName	is the name of the library to search for symbol.

Returns

the symbol object if found, otherwise NULL.
