v0.13.0-beta3

lnav v0.13.0

Interface changes:

• The prompt is now a custom implementation instead of readline.
  Some highlights:

  • In the DB prompt: pressing CTRL+L will reformat the query and
    switch the prompt to multi-line mode; error locations will be
    highlighted.

  • In multi-line mode, you can click and drag the status bar above
    the prompt to resize the prompt.

  • Pressing CTRL+O in the prompt will transfer the prompt to
    contents to Visual Studio Code or the default text editor on
    macOS.
    You can then edit the file and run it from the | prompt with:

    |saved-prompt
    

  • When editing a regular expression, like the search prompt or
    for a filter, if the current pattern matches a line in the
    view, the following word will be suggested.
    For example, if the view has the text "foo bar baz" and you
    type "foo ", the prompt will suggest "bar" and you can then
    press TAB to complete.

  • In the history listing, an icon indicates if the command or
    query succeeded or failed.

  • Mouse input works as expected: left-click positions the cursor
    in a given location, and a click-drag will select text.
    A right-click will copy the selected text to the system
    clipboard.

• Pressing F1 in the prompt will show the help text for the
  prompt itself.
  The size of the prompt panel is expanded for readability.
• When reading from stdin, the files used to store the content
  will be rotated when they cross the /tuning/piper/max-size
  threshold.
  Previously, the name of the file in the TEXT view would just
  be "stdin", but now it includes the rotation number.
• The LOG and TEXT views will now display a message if they
  contain no content to make it clear to the user that they
  need to switch views or :open a file.
• The HIST view now supports bookmarks, so you can use the usual
  hotkeys to move to the next/previous time segment with
  errors/warnings/marks.
• In table cells, control characters are replaced with Unicode
  symbols and highlighted with the 'hidden' style from the theme.

Features:

• The :comment command will now switch the prompt to multi-line
  mode and does syntax highlighting for Markdown directives in the
  comment.
  The rendered Markdown will also now be shown in the preview panel.
• lnav code blocks in Markdown content now have a play button (▶)
  next to commands that you can click on to run the command.
• Scrolling right in the LOG view when at the start of a message
  can hide the timestamp/level fields in the message and insert a
  shorter timestamp column on the left side.
  The column should take less space than the existing field and
  aligns all timestamps across all log formats.
  This feature is gated by the /ui/views/log/time-column
  setting, with the following values:
  • disabled: scrolling right works as normal and does not insert
    the time column.
  • enabled: scrolling right enables the time column.
  • default: the time column is enabled and the default on startup.
• Added a fuzzy_match() SQL function that compares a pattern to
  a string and returns a score.
  The algorithm used is the same as in lnav itself.
• Added a match_rowid column to search tables to make it easier
  to join multiple search tables together.
  For example, when multiple log messages occur together in the
  same sequence.
  You can create search tables for each line and then join them
  to query over the whole group of messages.
• Added a :write-debug-log-to command that can be used to write
  lnav's internal debug log to a file.
• Added a :clear-adjusted-log-time command to clear the time offset
  set by the :adjust-log-time command.
• Added a measure_with_units SQLite collation function that can
  compare numbers with unit suffixes, like "10KB" or "1.2ms".
  The :create-search-table command will also use this collation
  function for capture patterns that are likely to capture a number
  with a unit.
• Log messages now have permalinks that can be used to reference them
  from other locations.
  The permalink for a message is shown in the parser details overlay
  (activated by pressing p).
  Selecting the "Permalink:" line in the overlay and then pressing
  c will copy the link to your clipboard.
  The link is also available in the log_line_link column of the
  log tables.
  These permalinks can be used with the :goto command to move to
  the log message.
  They can also be used in log message comments as targets for
  Markdown links, which can be clicked to jump to the message.
• The CTRL + O shortcut is now bound to the :prev-location
  command, so you can jump back to a previous location.
• Render task marks in markdown.
• The demultiplexing feature has been extended to support JSON-lines
  input files.
  For example, an
  export of search results from Graylog
  can automatically be split into separate streams based on the
  source property.
• Added an lnav_focused_msg SQL VIEW that returns a single row
  with the columns from the all_logs table for the currently
  focused log message. An UPDATE of the mutable columns will
  update the corresponding row in the all_logs table.

Bug Fixes:

• Should start up in tmux and line drawing should show up now as well.
• The default terminal colors will now be used in the default theme.
  So, a light background with a dark foreground will be respected.
• Improved performance of searches with lots of hits.
• Improved performance for compressed files.
• Improved performance for the timeline view.
• Copying a column with a text value in the DB overlay view.
• Generic logs read from stdin or exec'd were not working properly.
• The :export-session-to command will now include :open commands
  for log files that were piped in to lnav or executed with the :sh
  command.
• The :set-file-timezone command was not working correctly in some
  cases.
• The location of views should be restored from the session when filters
  are active.

v0.12.4

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.
• The "Op ID:" overlay that is added when the log_opid field is
  manually set on a message can now be hidden by hiding the
  log_opid field.
• Pasting a command snippet when the input focus is on the main
  view will now execute it.
  For this to work: the terminal must support "bracketed-paste"
  mode, which most do;
  and, the pasted content must also start with one of the sigils
  for the desired operation (i.e. : for lnav commands, ; for SQL
  queries, / for searches, and | for scripts).
• 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 <format-name> test <path> 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.
• Added highlighting for Markdown syntax.

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.
• If the terminal supports less than 256 colors, a help message
  will be displayed to try setting TERM to xterm-256color.
• Added F1 as a hotkey to open the help view.
• Fixed some issues with scrolling in the main view when:
  word-wrap was enabled; log messages had tags/comments; or
  if the parser details overlay was open.

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.
• Added arm64 builds for Linux/macOS

v0.12.3

lnav v0.12.3

Features:

• Files that contain a mixture of log messages from separate
  services (e.g. docker logs) can now be automatically
  de-multiplexed into separate files that lnav can digest.
• The log_opid column on log vtables can now be UPDATEd
  so that you can manually set an opid on log messages that
  don't have one. Setting an opid allows messages to show
  up in the timeline view.
• The Files panel now has a details view on the right side
  that shows extra information about the selected file.
  You can look here for details of why lnav selected a
  particular log format.
• Add support for GitHub Markdown Alerts.
• Added the :xopen command that will open the given paths
  using an external opener like open or xdg-open.
• Clicking on a link in a markdown file will open the Actions
  with the following options:
  • opening the link target in lnav or, if it's an lnav script,
    executing the script;
  • opening the target with :xopen;
  • or, copying the link to the clipboard.
• Added a crash upload command to the management CLI that will
  upload crash logs to a server for analysis.
• Added a :set-text-view-mode command that controls whether
  file contents, such as markdown, are rendered or shown in
  their raw state.
• Text files with lines longer than 1024 characters will be
  automatically pretty-printed. You can revert to the raw view
  using the :set-text-view-mode command. The character limit
  can be adjusted with the
  /tuning/textfile/max-unformatted-line-length configuration
  setting.
• Added a pretty_print() SQL function that provides the same
  functionality as the PRETTY view.
• Keymap definitions can now bind to a function key using an
  identifier that starts with f followed by the number of the
  function key.
• Added log formats for the env_logger and simple_logger Rust
  crates.
• Timestamp formats can now use %j to capture day-of-year values.

Interface Changes:

• The "Gantt Chart" view has been renamed to "timeline."
• In the timeline view, pressing ENTER will focus on
  the preview pane, so you can scroll through messages
  with the selected Op ID.
• With mouse mode enabled, CTRL can be used as an alternate
  to SHIFT when clicking/dragging in the main view to
  highlight lines. A few terminals capture shift+clicks as a
  way to select text and do not pass them to the application.
• Clicking on an internal link in a Markdown document will move
  to that section.

Bug Fixes:

• Log messages in formats with custom timestamp formats were
  not being converted to the local timezone.
• The timezone offset is now shown in the parser details
  overlay for log messages.
• If a theme does not define cursor-line or selected-text
  styles, the styles from the default theme will be used.
• The first argument to a script is now the full path of the
  script and not just the script name.

Maintenance:

• You can now do an UPDATE on the lnav_top_view SQL view.
  This makes it easier to write queries that manipulate the
  current view.
• Upgrade to C++17

• Keymap definitions can now bind to a function key using an
  identifier that starts with f followed by the number of the
  function key.
• Added log formats for the env_logger and simple_logger Rust
  crates.
• Timestamp formats can now use %j to capture day-of-year values.

Interface Changes:

• The "Gantt Chart" view has been renamed to "timeline."
• In the timeline view, pressing ENTER will focus on
  the preview pane, so you can scroll through messages
  with the selected Op ID.
• With mouse mode enabled, CTRL can be used as an alternate
  to SHIFT when clicking/dragging in the main view to
  highlight lines. A few terminals capture shift+clicks as a
  way to select text and do not pass them to the application.
• Clicking on an internal link in a Markdown document will move
  to that section.

Bug Fixes:

• Log messages in formats with custom timestamp formats were
  not being converted to the local timezone.
• The timezone offset is now shown in the parser details
  overlay for log messages.
• If a theme does not define cursor-line or selected-text
  styles, the styles from the default theme will be used.
• The first argument to a script is now the full path of the
  script and not just the script name.

Maintenance:

• You can now do an UPDATE on the lnav_top_view SQL view.
  This makes it easier to write queries that manipulate the
  current view.
• Upgrade to C++17

v0.12.2

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.
