lnav v0.12.4

Features:

• Log message timestamps are now represented with microsecond
  precision internally instead of just millisecond.
• The log_time and log_level fields can now be hidden.
• Added a report-access-log script that generates a report that
  is similar to the output of the goaccess
  utility.
• Added a find-msg script that can be used to find the
  next/previous message with a field that matches the value of the
  field in the focused message.
• Added a find-chained-msg script that can be used to find the
  next/previous message where a target field matches the value of
  the source field in the focused message.
• Scripts can now specify their output format using the
  @output-format: documentation description.
  This setting can affect the output of some commands, like
  :write-table-to which will output Markdown tables when the
  output is set to text/markdown.
• Column alignment in Markdown tables is now supported.
• Added ecs_log for the Elastic Common Schema from @ba-didi.
• Added a Proxifier log format.
• Escape sequences for 24-bit color are now handled.
• The -i option for installing files will now copy .lnav
  script files to the formats/installed directory.
• Added italic and strike to the text styling configuration.
• DB query results can now be styled on a row-by-row basis by
  adding a column with the name __lnav_style__.
• Added "format test" management command to make it
  easier to test a format against a file.
  This can be helpful for determining why a file is not being
  recognized by particular format.
• Added a "performance" section to the documentation.
• Session exports now include :hide-fields and :show-fields
  commands from the session.
  They are currently commented out by default.

Interface changes:

• DB query results that start with a number are right justified
  instead of only full numbers.
• Left-clicking a local link in a Markdown document will jump to
  that section of the document instead of opening the overlay
  menu.
  You can still open the overlay menu by right-clicking on the link.
• Rows in a Markdown table are now highlighted with alternating
  styles.
• Long-running SQL queries in scripts are now mentioned in the UI
  to make it easier to see what is going on.
• Defining a value in a log format with the same name as one of
  predefined columns in the log virtual tables will now generate
  an error.
• The DB view will now chart result columns that contain a number
  with a unit, like "KB", "MB", "GB", etc...
• When switching to the pretty view, the focused line should be
  in the same position in the text as in the source view.
• In the LOG view, you can now copy the value of a field by
  pressing c when focused on a line in the parser details
  overlay (activated by pressing p).
• In the DB View, if there is a column named log_level, it
  will be used as the level for the row and the hotkeys for
  jumping to the next/previous error/warning will work.
• In the DB View, columns can now be hidden/shown using the
  :hide-fields / :show-fields commands.
• In the DB View, pressing p now works for all rows and will
  show all columns and not just JSON ones.
  You can then press c while focused in the overlay to copy
  the value of the column.
  Pressing space while focused on a column in the overlay will
  hide/show it.

Breaking changes:

• The parse_url() SQL function no longer raises an error for an
  invalid URL.
  Instead, it will return a JSON object with an object with the
  following properties:
  • error - An identifier for the error.
  • url - The invalid URL itself.
  • reason - A description of the error.

Bug Fixes:

• Reduced startup time.
• Reduced indexing time for plain text and JSON-lines logs.
• Reduced memory footprint.
• Improved search performance.
• Reduced DB view CPU and memory usage.
• Reduce time to open help text.
• Improved performance of log virtual tables when ordering the
  result by log_line DESC.
• Improved performance of the spooky_hash() SQL function.

Maintenance:

• Replaced ncurses with notcurses.
