Detailed Description

Manage LIB_TABLE_ROW records (rows), and can be searched based on library nickname.

This class owns the 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 library table has 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 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.

Constructor & Destructor Documentation

LIB_TABLE()

LIB_TABLE::LIB_TABLE

(

LIB_TABLE *

aFallBackTable = nullptr

)

Build a library table by pre-pending this table fragment in front of aFallBackTable.

Loading of this table fragment is done by using Parse().

Parameters

aFallBackTable

is another LIB_TABLE which is searched only when a row is not found in this table. No ownership is taken of aFallBackTable.

Definition at line 124 of file lib_table_base.cpp.

InsertRow()

Adds aRow if it does not already exist or if doReplace is true.

If doReplace is not true and the key for aRow already exists, the function fails and returns false.

The key for the table is the nickName, and all in this table must be unique.

Parameters

aRow	is the new row to insert, or to forcibly add if doReplace is true.
doReplace	if true, means insert regardless of whether aRow's key already exists. If false, then fail if the key already exists.

Returns

bool - true if the operation succeeded.

Parse the #LIB_TABLE_LEXER s-expression library table format into the appropriate LIB_TABLE_ROW objects.

Parameters

aLexer

is the lexer to parse.

Exceptions

IO_ERROR	if an I/O error occurs during parsing.
PARSER_ERROR	if the lexer format to parse is invalid.
boost::bad_pointer	if an any attempt to add an invalid pointer to the boost::ptr_vector.
boost::bad_index	if an index outside the row table bounds is accessed.

Implemented in SYMBOL_LIB_TABLE, FP_LIB_TABLE, and TEST_LIB_TABLE.

ParseOptions()

PROPERTIES * LIB_TABLE::ParseOptions ( const std::string &  aOptionsList )

static

Parses aOptionsList and places the result into a PROPERTIES object which is returned.

If the options field is empty, then the returned PROPERTIES will be a NULL pointer.

Typically aOptionsList comes from the "options" field within a LIB_TABLE_ROW and the format is simply a comma separated list of name value pairs. e.g.: [name1[=value1][|name2[=value2]]] etc. When using the UI to create or edit a library table, this formatting is handled for you.
