v0.23.1

• Fixed a bug that caused an I/O error when Sqawk read a lot of data from standard input.

v0.23.0

• A parser for JSON and JSON Lines has been added.
• Unknown per-file options cause an error. No more silent typos!
• The parser/serializer options arrays and dicts are unified into one option: kv (for "key-value"). kv=true acts as dicts=true; kv=false acts as arrays=true.
• The indent option for the JSON serializer is renamed to pretty.
• The Tcl serializer has new options: lines and pretty.
• New SQLite functions are added for working with Tcl data: dict_exists, dict_get, lindex, llength, lrange, regexp, regsub.
• Error messages are valid Tcl lists.

v0.22.1

This is a bugfix release.

• Fixed Sqawk creating an empty file named close in the current directory.

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.

v0.21.0

Changes in this version include:

• The new file option fields for the default parser awk lets you skip as well as merge parts of the input. It replaces the option merge.
• You can disable the zeroth column (a0, b0, etc.) with the file option F0.
• The zeroth column no longer counts towards NF.
• raw is no longer a synonym for the parser awk.
• The README has been much improved.
