- Interpreter and compiler have been improved to work correct, when
a derived struct overrides an element of the parent struct. Many
thanks go to Zachary Menzies, for reporting this error and for
providing a test program.
- In the FAQ the explanation, why Seed7 uses UTF-32, has been improved.
An explanation of the database abstraction layer, which provides an
database independent API, has also been added to the FAQ.
- In the manual the chapter about the deprecated function
removeAnyFile() has been replaced by a chapter about the function
removeTree().
- The program db7.sd7 (Database Inspector) has been improved quote a
table name from the catalog when doing a select.
- The program sql7.sd7 has been improved to allow the execution of SQL
statements from a file. The function getSqlStatement has been added,
which reads a semicolon terminated SQL statement from a file.
- The library tar.s7i has been improved to accept extended headers with
meta data (PAX format) also when a tar file is opened as file system
with openTar(). The function readMinimumOfHead has been improved to
do this.
- A code page for JIS X 0201 encoding has been added to charsets.s7i.
- The program err.sd7 has been improved to contain test cases, where
UTF-16 surrogate characters and non Unicode characters are written as
Seed7 string escape sequences.
- In sql_oci.c the function sqlOpenOci() has been improved to allow
opening a database with host name, port and database name. This way a
database can be opened without an entry in tnsnames.ora. The type
connectDataRecord and the function setupConnectData() have been added
to sql_oci.c.
- The functions sqlOpenMy (in sql_my.c) and sqlOpenPost (in sql_post.c)
have been improved to allow opening a database with host name, port
and database name. Now host, port and dbName are parameters. Before
the functions split the parameter dbName into host and database name.
Specifying a port was not possible.
- In sql_odbc.c the function sqlOpenOdbc() has been improved to allow
opening a database with ODBC driver name, server name and database
name. This way a database can be opened without specifying a data
source in the ODBC Data Source Administrator (in the Control Panel).
The type connectDataRecord and the functions getRegularName(),
wstriSearchCh(), wstriSearch(), connectToServer(), connectToDriver()
and driverConnect() have been added to sql_odbc.c. A definition of
SQL_NEED_DATA has been added to db_odbc.h.
- In sql_rtl.c the function sqlErrMessage() has been improved to allow
database error messages encoded in UTF-8.
- The function sqlOpen() has been removed from sql_rtl.c.
- The function width() has been added to string.s7i and seed7_05.s7i.
This function computes the sum of the character widths in a string.
A character width can be 0 (for control characters), 1 (for normal
printable characters) and 2 (for fullwidth characters, e.g. KANJI).
- The library console.s7i has been improved to use the function
