v0.12.1a-beta2

lnav v0.12.1

Features:

• Database queries can now be written in
  PRQL. When executing a query with ;,
  if the query starts with from, it will be treated as PRQL.
  The pipeline structure of PRQL queries is more desirable for
  interactive use since lnav can make better suggestions and
  show previews of the stages of the pipeline.
• Log partitions can automatically be created by defining a log
  message pattern in a log format. Under a format definition,
  add an entry into the "partitions" object in a format definition.
  The "pattern" property specifies the regular expression to match
  against a line in a file that matches the format. If a match is
  found, the partition name will be set to the value(s) captured
  by the regex. To restrict matches to certain files, you can add
  a "paths" array whose object elements contain a "glob" property
  that will be matched against file names.

Interface changes:

• When using PRQL in the database query prompt (;),
  the preview pane will show the results for the pipeline
  stage the cursor is within along with the results of
  the previous stage (if there is one). The preview
  works on a limited data set, so the preview results
  may differ from the final results.
• Changed the breadcrumb bar styling to space things out
  more and make the divisions between items clearer.
• The ESC key can now be used to exit the files/filters
  configuration panel instead of q. This should make
  it easier to avoid accidentally exiting lnav.
• Added some default help text for the command prompt.
• Suggestions are now shown for some commands and can
  be accepted by pressing the right arrow key. For
  example, after typing in :filter-in the current
  search term for the view will be suggested (if
  one is active).
• The focused line should be preserved more reliably in
  the LOG/TEXT views.
• In the LOG view, the current partition name (as set
  with the :partition-name command) is shown as the
  first breadcrumb in the breadcrumb bar. And, when
  that breadcrumb is selected, you can select another
  partition to jump to.
• The { / } hotkeys, :next-section, and :prev-section
  commands now work in the LOG view and take you to the
  next/previous partition.
• The DB view now defaults to not showing bar charts.

Breaking changes:

• Many of the lesser used column in the log format tables
  (e.g. log_tags) have been moved to after the columns
  defined by the format. These columns are usually NULL
  and are a distraction when previewing queries.
