v0.22.0

Changes in this version include:

• New command line options:
  • -dbfile to store the SQLite database on disk rather than in memory. It lets you parse the data once and query it later, saving time.
  • -noinput, which stops Sqawk from reading from the standard input if it is given no input files. Use it with -dbfile when you only want to query an existing database file.
• The script can now to be empty. This is useful with -dbfile.
• You can insert data into an existing table over multiple invocations of Sqawk (with -dbfile) or in a single invocation with several input sources.
• Most of the input parsers and the output serializers are now lazy. This results in:
  • A massive reduction in memory usage (e.g., inserting 1 000 000 rows now takes 40 MiB, not 900 MiB), which makes it feasible to work with larger datasets even in memory.
  • Approximately 20% slower parsing and serialization, a price well worth paying in the developer's view.
