HTSQL 2.1.0b3 is released
Published by xi on 2011-05-13
A new beta of the 2.1 release is now available.
Changes since the last beta:
- Added a fiber linking operator; see Linking Operator.
- Provide named attributes for kernel expressions and the complement
link in a quotient scope; for more details, see
Projection Namespace.
- Added in-selector definitions; see Selector Shortcuts.
- Added $reference syntax for inter-scope references; for more
details and rationale, see References.
- Added flow method fork(): clone the last node in the flow, e.g.
/course?credits=max(fork().credits).
- Added flow methods filter() and select() as aliases to ?
and {} operators.
- Added method distinct(): distinct(table{kernel}) produces
a flow of unique values of kernel as it runs over table;
it is equivalent to table^kernel. distinct() and ^ operators
now filter out NULL values in the kernel.
- Changed semantics of and {} expressions: specifier ()
now allows arbitrary expressions on both sides, selector ({})
now sets the output columns in the current scope.
- Added syntax *N, where N is an integer literal, to get the value
of the N-th output column.
- Added addon tweak.cors: append Access-Control-Allow-Origin: *
to every HTTP response.
- Added addon tweak.pgsql.inet: basic manipulations on values
of INET data type.
- Added addon tweak.pgsql.view: determine foreign key relationships
for views in Postgresql.
- Use search_path or its analogues to choose a table when
the table name is ambiguous.
- Optimized introspection for Oracle.
- Added option -p to ask for a password on startup.
- Added shell command run filename.htsql to load and execute
an HTSQL query from a file.
- Many other fixes and documentation updates.
