* This class owns the footprint library table, which is like fstab in concept and maps * logical library name to the library URI, type, and options. It is heavily based on the SWEET * parser work done by Dick Hollenbeck and can be seen in new/sch_lib_table.h. A footprint * library table had the following columns: *

    *
  • Logical Library Name (Nickname) *
  • Library Type, used to determine which plugin to load to access the library. *
  • Library URI. The full URI to the library source, form dependent on Type. *
  • Options, used for as yet to be defined information such as user names or passwords *
*

* The Library Type can be one of: *

    *
  • "file" *
  • "ftp" *
  • "http" *
*

* For now, the Library URI types needed to support the various types can be one of those * shown below, which are typical of each type: *

    *
  • "file://C:/mylibdir" *
  • "ftp://kicad.org/partlib/trunk" *
  • "http://kicad.org/partlib" *
*

* The footprint library table is built up from several additive entries (table fragments), * and the final table is a (conceptual) merging of the table fragments. Two * anticipated sources of the entries are a personal table saved in the KiCad configuration * and a project resident table that resides in project file. The project footprint table * entries are considered a higher priority in the final dynamically assembled library table. * An row in the project file contribution to the library table takes precedence over the * personal table if there is a collision of logical library names. Otherwise, the entries * simply combine without issue to make up the applicable library table. * * @author Wayne Stambaugh */ class FP_LIB_TABLE { friend class DIALOG_FP_LIB_TABLE; public: /** * Class ROW * holds a record identifying a footprint library accessed by the appropriate #PLUGIN * object in the #FP_LIB_TABLE. */ class ROW { friend class FP_LIB_TABLE; friend class DIALOG_FP_LIB_TABLE; public: typedef IO_MGR::PCB_FILE_T LIB_T; ROW() : type( IO_MGR::KICAD ) { } ROW( const wxString& aNick, const wxString& aURI, const wxString& aType, const wxString& aOptions ) : nickName( aNick ), uri( aURI ), options( aOptions ) { SetType( aType ); } bool operator==( const ROW& r ) const { return nickName==r.nickName && uri==r.uri && type==r.type && options==r.options; } bool operator!=( const ROW& r ) const { return !( *this == r ); } /** * Function GetNickName * returns the short name of this library table row. */ const wxString& GetNickName() const { return nickName; } /** * Function GetType * returns the type of LIB represented by this record. */ const wxString GetType() const { return IO_MGR::ShowType( type ); } /** * Function GetFullURI * returns the full location specifying URI for the LIB. */ const wxString& GetFullURI() const { return uri; } /** * Function GetOptions * returns the options string, which may hold a password or anything else needed to * instantiate the underlying LIB_SOURCE. */ const wxString& GetOptions() const { return options; } /** * Function Format * serializes this object as utf8 text to an OUTPUTFORMATTER, and tries to * make it look good using multiple lines and indentation. * @param out is an #OUTPUTFORMATTER * @param nestLevel is the indentation level to base all lines of the output. * Actual indentation will be 2 spaces for each nestLevel. */ void Format( OUTPUTFORMATTER* out, int nestLevel ) const throw( IO_ERROR ); /** * Function SetNickName * changes the logical name of this library, useful for an editor. */ void SetNickName( const wxString& aNickName ) { nickName = aNickName; } /** * Function SetType * changes the type represented by this record. */ void SetType( const wxString& aType ) { type = IO_MGR::EnumFromStr( aType ); } /** * Function SetFullURI * changes the full URI for the library, useful from a library table editor. */ void SetFullURI( const wxString& aFullURI ) { uri = aFullURI; } /** * Function SetOptions * changes the options string for this record, and is useful from * the library table editor. */ void SetOptions( const wxString& aOptions ) { options = aOptions; } private: wxString nickName; wxString uri; LIB_T type; wxString options; }; /** * Constructor FP_LIB_TABLE * builds a library table by pre-pending this table fragment in front of * @a aFallBackTable.
