lnav v0.12.2

Features:

• Added mouse support that can be toggled with F2 or enabled
  by default with: :config /ui/mouse/mode enabled. With
  mouse support enabled, many of the UI elements will respond to
  mouse inputs:

  • clicking on the main view will move the cursor to the given
    row and dragging will scroll the view as needed;
  • shift + clicking/dragging in the main view will highlight
    lines and then toggle their bookmark status on release;
  • double-clicking in the main view will select the underlying
    text and drag-selecting within a line will select the given
    text;
  • when double-clicking text: if the mouse pointer is inside
    a quoted string, the contents of the string will be selected;
    if the mouse pointer is on the quote, the quote will be included
    in the selection; if the mouse pointer is over a bracket
    (e.g. [],{},()) where the matching bracket is on the same line,
    the selection will span from one bracket to the other;
  • when text is selected, a menu will pop up that can be used
    to filter based on the current text, search for it, or copy
    it to the clipboard;
  • right-clicking the start of a log message in the main view
    will open the parser details overlay;
  • the parser details now displays a diamond next to fields to
    indicate whether they are shown/hidden and this can be
    clicked to toggle the state;
  • the parser details will show a bar chart icon for fields with
    values which, when clicked, will open either the spectrogram
    view for the given field or open the DB query prompt with a
    PRQL query to generate a histogram of the field values;
  • clicking in the scroll area will move the view by a page,
    double-clicking will move the view to that area, and
    dragging the scrollbar will move the view to the given spot;
  • clicking on the breadcrumb bar will select a crumb and
    selecting a possibility from the popup will move to that
    location in the view;
  • clicking on portions of the bottom status bar will trigger
    a relevant action (e.g. clicking the line number will open
    the command prompt with :goto <current-line>);
  • clicking on the configuration panel tabs (i.e. Files/Filters)
    will open the selected panel and clicking parts of the
    display in there will perform the relevant action (e.g.
    clicking the diamond will enable/disable the file/filter);
  • clicking in a prompt will move the cursor to the location;
  • clicking on a column in the spectrogram view will select it.

  (Note that this is new work, so there are likely to be some
  glitches.)

• Added a journald:// URL handler that will call journalctl
  and pass any query parameters as options. For example, the
  following command:

  $ lnav 'journal://?since=yesterday'
  

  Will execute the following and capture the output:

  journalctl --output=json -f --since=yesterday
  

• Added the "last-word" line-format field shortening algorithm
  from @flicus.

• Added a stats.hist PRQL transform that produces a histogram
  of values over time.

• The preview for the :open command will now show a listing
  of archive contents.

• Added humanize_id SQL function that colorizes a string using
  ANSI escape codes.

• Added a selected_text column to the lnav_views table that
  reports information about text that was selected with a mouse.
  This makes it possible to script operations that use the
  selected text as an input.

• Added breadcrumb as an option to the :prompt command so
  that the breadcrumb hotkey can be configured.

Interface changes:

• The bar charts in the DB view have now been moved to their
  individual columns instead of occupying the whole width of
  the view. The result is much cleaner, so the charts are
  now enabled by default again.

• Cursor mode in the main view is now the default instead of
  using the top line as the focus. You can change back by
  running:

  :config /ui/movement/mode top

• In the parser details panel (opened by pressing p), you
  can now hide/show fields by moving the cursor line to the
  given field and pressing the space bar or by clicking on
  the diamond with the mouse.

• The sv keymap binds § to focus the breadcrumb bar.

Bug Fixes:

• With the recent xz backdoor shenanigans, it seems like a good
  time to add some checks for data being hidden by escape codes:
  • File names with escape sequences are now displayed in quotes
    with backslash escapes.
  • Text that has the same foreground and background colors will
    have the background set to a contrasting color.
• Sub-millisecond time values should now be preserved when
  displaying JSON-lines logs.
• A crash during initialization on Apple Silicon and MacOS 12
  has been fixed.
• A crash when previewing non-text files.
• Optimized ANSI-escape processing.
• Various fixes to make lnav usable as a PAGER.

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.

lnav v0.12.0

Features:

• Added a Gantt Chart view to visualize operations over time
  based on the "opid" in log messages. The view shows
  the operation IDs, a description of the operation captured
  from log messages, and a bar representing the period of
  time that the operation was running.
• Added the :sh command and -e option to execute a shell
  command-line and display its output within lnav. The
  captured output will be displayed in the TEXT view. The
  lines from stdout and stderr are recorded separately so
  that the lines from stderr can be shown in the theme's
  "error" highlight. The time that the lines were received
  are also recorded internally so that the "time-offset"
  display (enabled by pressing Shift + T) can be shown
  and the "jump to slow-down" hotkeys (s/Shift + S)
  work. Since the line-by-line timestamps are recorded
  internally, they will not interfere with timestamps that
  are in the commands output.
• Added a :cd command to change lnav's current directory.
• Added support for automatically converting files that are
  in a format not natively supported by lnav. The new
  converter section in a log format definition allows you
  to specify how a file type can be detected and converted.
  The built-in PCAP support in lnav is implemented using
  this mechanism.
• Added a shell_exec() SQLite function that executes a
  command-line with the user's $SHELL and returns the
  output.
• Added support for custom URL schemes that are handled by an
  lnav script. Schemes can be defined under
  /tuning/url-schemes. See the main docs for more details.
• Added docker:// and podman:// URL schemes that can be
  used to tail the logs for containers (e.g.
  docker://my-container) or files within a container (e.g.
  docker://my-serv/var/log/dpkg.log). Containers mentioned
  in a "Compose" configuration file can be tailed by using
  compose as the host name with the path to the configuration
  file (e.g. docker://compose/compose.yaml).
• Added an :annotate command that can trigger a call-out
  to a script to analyze a log message and generate an
  annotation that is attached to the message. The script
  is executed asynchronously, so it will not block input
  and the result is saved in the session. Annotations are
  defined in the /log/annotations configuration property.
• Timestamps with numeric timezone offsets (or Z) are now
  automatically converted to the local time zone. For
  example, a timestamp ending in -03:00 will be treated
  as three hours behind UTC and then adjusted to the local
  timezone. This feature can be disabled by setting the
  /log/date-time/convert-zoned-to-local configuration
  property to false. Timestamps without a zone or have
  a symbolic zone name (e.g. PDT) are not converted.
• Added the SQLite JSON functions to the online help.
• Added config get and config blame management CLI
  commands to get the current configuration and the file
  locations where the configuration options came from.
• When piping data into lnav's stdin, the input used to
  only be written to a single file without any rotation.
  Now, the input is written to a directory of rotating files.
  The same is true for the command-lines executed through the
  new :sh command. The piped data can be managed using the
  new piper commands in the management CLI.
• The $LNAV_HOME_DIR and $LNAV_WORK_DIR environment
  variables are now defined inside lnav and refer to
  the location of the user's configuration directory and
  the directory where cached data is stored, respectively.
• The <pre> and <img> tags are now recognized in
  Markdown files.
• The style attribute in <span> tags is now supported.
  The following CSS properties and values are supported:
  • color and background-color with CSS color names
  • font-weight with a value of bold or bolder
  • text-decoration with underline
  • border-left and border-right with the solid,
    dashed and dotted line styles and colors.
• Added an options column to the lnav_views table
  to allow more control over overlays.
• Added a "Dracula" theme as described at:
  https://draculatheme.com
• Added the following styles for themes:
  • /ui/theme-defs/<theme_name>/syntax-styles/inline-code
  • /ui/theme-defs/<theme_name>/syntax-styles/type
  • /ui/theme-defs/<theme_name>/syntax-styles/function
  • /ui/theme-defs/<theme_name>/syntax-styles/separators-references-accessors
• Multi-line block comments (i.e. /* ... */) and strings
  are now recognized and styled as appropriate.
• Added error and data columns to the fstat()
  table-valued-function. The error column is non-NULL
  if there is a problem accessing the file. The data
  contains the contents of the file, as such, it is
  hidden by default.
• Added a log format for Redis.
• The :eval command will now treat its argument(s) as a
  script, allowing multiple commands to be executed.
• Added a timezone() SQL function for converting a timestamp
  to a target timezone.
• Added a :convert-time-to command that converts the
  timestamp of the focused log message to the given timezone.
• Added the :set-file-timezone and :clear-file-timezone
  commands to set the timezone for log messages that don't
  include a zone in their timestamp.
• Added the options_path and options columns to the
  lnav_file table so you can see what options are applied
  to a file. Currently, the only option is the default
  timezone that is set by the :set-file-timezone command.
• Added the config file-options management command that
  can be used to examine the options that will be applied
  to a given file.
• When viewing a diff, the sections of the diff for each
  file is recognized and shown in the breadcrumb bar. So,
  you can see the file the focused line is in. You can
  also jump to a particular file by focusing on the
  breadcrumb bar, selecting the crumb, and then selecting
  the desired file.
• Binary files are now displayed as a hex dump with ASCII
  representation (where applicable).
• Added a log_msg_line() SQL function that will return the
  line number of the start of the currently focused
  message in the log view.
• Added a log_msg_values column to the all_logs SQL
  table that contains a JSON object with the top 5 values
  for the fields extracted from the log message.
• Added :next-section and :prev-section commands for
  moving to the next and previous section of a document.
  For example, the next section in a man page or JSON
  array. The default keymap has been changed to bind
  the curly brace keys to these commands.
• Added Nextcloud log format from Adam Monsen.
• Added GitHub Event Log format for files from gharchive.org.
  It makes a good example of a JSON-Lines format.

Bug Fixes:

• Binary data piped into stdin should now be treated the same
  as if it was in a file that was passed on the command-line.
• The -I option is now recognized in the management CLI
  (i.e. when you run lnav with the -m flag).
• Fields in the bro and w3c log formats that were hidden are
  now saved in the session and restored.
• A warning will now be issued if a timestamp in a log format's
  sample message does not match completely. Warnings in the
  configuration can be viewed by passing the -W flag.
• Importing from regex101.com broke due to some changes in the
  API.
• The details overlay for a log message no longer shows keys
  for unknown JSON properties. These extra fields are now
  shown with the proper jget(log_raw_text, '/...') SQL
  expression needed to retrieve the value.
• Improved text-wrapping when rendering Markdown.

Interface changes:

• The breadcrumb bar hotkey is moving to backtick `
  instead of ENTER.
• The DB view now uses the "alt-text" theme style to draw
  alternating rows instead of being hard-coded to bold. The
  alternation is also now done in groups of two rows instead
  of only a single row. Numbers are also rendered using the
  "number" theme style as well.
• The log message overlay in the LOG view is now limited
  2/3rds of the height. You can focus on the overlay panel
  by pressing CTRL-]. The "alt-text" theme style is also
  used to draw the overlay contents now as well. (The
  overlay is used to display the parser details, comments,
  and annotations.)
• The { and } keys have been changed from moving
  through the "location history" to moving to the previous
  and next section in a document.
• Added indent guidelines when structured data is detected.

Breaking changes:

• Removed the -w command-line option. This option was
  useful when stdin was not automatically preserved. Since
  the data is now stored (and cleaned up) as well as being
  spread across multiple files, this option doesn't make
  sense anymore.
• The -t command-line flag behaves a little differently
  behind the scenes now. Timestamps will always be
  recorded for each line piped into lnav. This flag means
  that the data should be treated as a log file instead of
  plain text.
• Data piped into lnav is now stored in the work
  directory instead of the stdin-captures dot-lnav
  directory.
• Changed the "Bunyan" log format name from bunyan to
  bunyan_log to be consistent with other format names.

lnav v0.11.2

Features:

• A "cursor" mode has been added to the main view that can
  be toggled by pressing CTRL-X. While in cursor mode, any
  operations that would normally work on the "top" line will
  now operate on the focused line instead.
• Added CTRL-D and CTRL-U hotkeys to move down/up by half
  a page.
• Added an auto-width flag to the elements of the
  line-format array that indicates that the width of the
  field should automatically be determined by the observed
  values.
• Added bunyan log format from Tobias Gruetzmacher.
• Added cloudflare log format from @minusf.
• Number fields used in a JSON log format line-format
  array now default to being right-aligned. Also, added
  prefix and suffix to line-format elements so a
  string can optionally be prepended/appended if the value
  is not empty.
• JSON log format detection has been improved to not rely
  on matching the file name. All possible formats are
  tried and the one with the most available fields for a
  given line-format is used. For example, if the first
  log message has 8 fields and format A contains 5 of
  those fields in its line-format while format B only
  contains 2 of those fields in its line-format, format
  A will be used for the file.

Changes:

• For JSON-lines logs, line-feeds at the end of a value are
  automatically stripped.

Bug Fixes:

• Hidden values in JSON logs are now hidden by default.
• Text with ANSI-escapes is now filtered properly.
