Raw Blame History

lnav v0.10.2:
Features:
* Redesigned the top status bar to make it display breadcrumbs that
are interactive. Pressing ENTER will activate the breadcrumb bar
and the left/right cursor keys can be used to select a particular
crumb while the up/down keys can select a value to switch to.
While a crumb is selected, you can also type in some text to do
a fuzzy search on the possibilities or, if the crumb represents
an array of values, enter the index to jump to.
* The pretty-print view will now show breadcrumbs that indicate the
location of the top line in the view with the prettified structure.
* Added an integration with regex101.com to make it easier to edit
log message regular expressions. Using the new "management CLI"
(activated by the -m option), a log format can be created from
a regular expression entry on regex101.com and existing patterns
can be edited.
* Add initial support for pcap(3) files using tshark(1).
* Added a "top_meta" column to the lnav_views table that contains
metadata related to the top line in the view.
* Added a "log_opid" hidden column to all log tables that contains
the "operation ID" as specified in the log format.
* Moved the "log_format" column from the all_logs table to a hidden
column on all tables.
* Add format for UniFi gateway.
Breaking Changes:
* Added a 'language' column to the lnav_view_filters table that
specifies the language of the 'pattern' column, either 'regex'
or 'sql'.
* Timestamps that do not have a day or month are rewritten to a
full timestamp like YYYY-MM-DD HH:MM:SS.
Fixes:
* Toggling enabled/disabled filters when there is a SQL expression
no longer causes a crash.
* Fix a crash related to long lines that are word wrapped.
lnav v0.10.1:
Features:
* Added ":show-only-this-file" command that hides all files except the
one for the top line in the view.
* The ":write-raw-to" command now accepts a --view flag that specifies
the source view for the data to write. For example, to write the
results of a SQL query, you would pass "--view=db" to the command.
* The commands used to access the clipboard are now configured through
the "tuning" section of the configuration.
* Added an "lnav_version()" SQL function that returns the current
version string.
* Added basic support for the logfmt file format. Currently, only files
whose lines are entirely logfmt-encoded are supported. The lines
must also contain either a field named "time" or "ts" that contains
the timestamp.
* Added the "logfmt2json()" SQL function to convert a string containing
a logfmt-encoded message into a JSON object that can be operated on
more easily.
* Added the "gzip()" and "gunzip()" SQL functions to compress values
into a blob and decompress a blob into a string.
Interface changes:
* The xclip implementation for accessing the system clipboard now writes
to the "clipboard" selection instead of the "primary" selection.
* The 'query' bookmark type and y/Y hotkeys have been removed due to
performance issues and the functionality is probably rarely used.
Bug Fixes:
* The text "send-input" would show up on some terminals instead of
ignoring the escape sequence. This control sequence was only
intended to be used in the test suite.
* Remote file synchronization has been optimized a bit.
* Configuration values loaded from the ~/.lnav/configs directory
are now included in the default configuration, so they won't be
saved into the ~/.lnav/config.json user configuration file.
* Key handling in the visual filter editor will no longer swallow
certain key-presses when editing a filter.
* Scrolling performance restored in the SQL view.
* The ':redirect-to' command now works with '/dev/clipboard'
* The field overlay (opened by pressing 'p') now shows 'log_time'
for the timestamp field instead of the name defined in the format.
* The search term in the bottom status bar will now update properly
when switching views.
* The "Out-Of-Time-Order Message" overlay will be shown again.
* The tab for the "Files" panel will be highlighted in red if there
is an issue opening a file.
* Overwritten files should be reloaded again.
* The "jget()" SQL function now returns numbers with the correct type.
* The "json_contains()" SQL function now returns false if the first
argument is NULL instead of NULL.
* The local copies of remote files are now cleaned up after a couple
days of the host not being accessed.
* The initial loading and indexing phase has been optimized.
lnav v0.10.0:
Features:
* Files on remote machines can be viewed/tailed if they are accessible
via SSH. The syntax for specifying the host and path is similar to
scp. For example, to view the files in the /var/log directory on the
machine "host1.example.org":
user@host1.example.org:/var/log
Note that you must be able to log into the machine without any
interaction.
* Added the ':filter-expr' command to filter log messages based on an SQL
expression. This command allows much greater control over filtering.
* Added the ':mark-expr' command to mark log messages based on an SQL
expression. This command makes it easier to programmatically mark
log messages compared to using SQL.
* Added support for archive files, like zip, and other compression formats,
like xz, when compiled with libarchive. When one of these types of
files is detected, they are unpacked into a temporary directory and
all of the files are loaded into lnav.
* Added an 'xpath()' table-valued function for extracting values from
strings containing XML snippets.
* Added the ':prompt' command to allow for more customization of prompts.
Combined with a custom keymapping, you can now open a prompt and prefill
it with a given value. For example, a key could be bound to the
following command to open the command prompt with ":filter-in " already
filled in:
:prompt command : 'filter-in '
* Added support for the W3C Extended Log File Format with the name
"w3c_log". Similarly to the bro log format, the header is used to
determine the columns in a particular file. However, since the columns
can be different between files, the SQL table only has a well-known set
of columns and the remainder are accessible through JSON-objects stored
in columns like "cs_headers" and "sc_headers".
* Added support for the S3 Access File Format.
* To jump to the first search hit above the top line in a view, you can
press CTRL+J instead of ENTER in the search prompt. Pressing ENTER
will jump to the first hit below the current window.
* Filtering, as a whole, can be now disabled/enabled without affecting
the state of individual filters. This includes text and time-filters
(i.e. :hide-lines-before). You can enable/disable filtering by:
pressing 'f' in the filter editor UI; executing the ':toggle-filtering'
command; or by doing an UPDATE on the "filtering" column of the
"lnav_views" SQLite table.
* Themes can now include definitions for text highlights under:
/ui/theme-defs/<theme_name>/highlights
* Added a "grayscale" theme that isn't so colorful.
* Added the humanize_file_size() SQL function that converts a numeric size
to a human-friendly string.
* Added the sparkline() SQL function that returns a "sparkline" bar made
out of unicode characters. It can be used with a single value or as
an aggregator.
* Added a "log_time_msecs" hidden column to the log tables that returns
the timestamp as the number of milliseconds from the epoch.
* Added an "lnav_top_file()" SQL function that can be used to get the
name of the top line in the top view or NULL if the line did not come
from a file.
* Added a "mimetype" column to the lnav_file table that returns a guess as
to the MIME type of the file contents.
* Added a "content" hidden column to the lnav_file table that can be used
to read the contents of the file. The contents can then be passed to
functions that operate on XML/JSON data, like xpath() or json_tree().
* Added an "lnav_top_view" SQL VIEW that returns the row for the top view
in the lnav_views table.
* The "generate_series()" SQLite extension is now included by default.
One change from the standard implementation is that both the start and
stop are required parameters.
* Added the ";.read" SQL command for executing a plain SQL file.
* Added the "-N" flag so that lnav will run without opening the default
syslog file.
Interface Changes:
* When copying log lines, the file name and time offset will be included
in the copy if they are enabled.
* Log messages that cannot be parsed properly will be given an "invalid"
log level and the invalid portions colored yellow.
* The range_start and range_stop values of the regexp_capture() results
now start at 1 instead of zero to match with what the other SQL string
functions expect.
* The ":write-cols-to" command has been renamed to ":write-table-to".
* The DB view will limit the maximum column width to 120 characters.
* The ":echo" command now evaluates its message to do variable
substitution.
* The ":write-raw-to" command has been changed to write the original
log file content of marked lines. For example, when viewing a JSON
log, the JSON-Line values from the log file will be written to the
output file. The ":write-view-to" command has been added to perform
the previous work of ":write-raw-to" where the raw content of the view
is written to the file.
Fixes:
* Unicode text can now be entered in prompts.
* The replicate() SQL function would cause a crash if the number of
replications was zero.
* Many internal improvements.
lnav v0.9.0:
Features:
* Added support for themes and included a few as well: default, eldar,
monocai, night-owl, solarized-light, and solarized-dark. The theme
can be changed using the ':config' command, like so:
:config /ui/theme night-owl
Consult the online documentation for defining a new theme at:
https://lnav.readthedocs.io/en/latest/config.html#theme-definitions
* Added support for custom keymaps and included the following: de, fr,
uk, us. The keymap can be changed using the ':config' command, like so:
:config /ui/keymap uk
Consult the online documentation for defining a new keymap at:
https://lnav.readthedocs.io/en/latest/config.html#keymap-definitions
* The following JSON-Schemas have been published for the log format and
configuration JSON files:
https://lnav.org/schemas/format-v1.schema.json
https://lnav.org/schemas/config-v1.schema.json
Formats should be updated to reference the schema using the "$schema"
property.
* Indexing of new data in log files can now be paused by pressing '='
and unpaused by pressing it again. The bottom status bar will display
'Paused' in the right corner while paused.
* CMake is now a supported way to build.
* When viewing data from the standard-input, a symbolic name can be used
to preserve session state. The name can be changed using the
"rename-stdin" lnav script or by doing an UPDATE to the filepath
column of the lnav_file table. For example, to assign the name
"journald", the following SQL statement can be executed in lnav:
;UPDATE lnav_file SET filepath='journald' WHERE filepath='stdin'
* The size of the terminal can be accessed in SQL using the $LINES and
$COLS variables.
* The raise_error(msg) SQL function has been added to make it easier to
raise an error in an lnav script to stop execution and notify the user.
* Added the json_concat() function to make it easier to append/concatenate
values onto arrays.
* Added the ":write-jsonlines-to" command that writes the result of a SQL
query to a file in the JSON Lines format.
Interface Changes:
* Data piped into lnav is no longer dumped to the console after exit.
Instead a file containing the data is left in .lnav/stdin-captures/
and a message is printed to the console indicating the file name.
* In time-offset mode, the deltas for messages before the first mark
are now negative instead of relative to the start of the log.
* The $XDG_CONFIG_HOME environment variable (or ~/.config directory) are
now respected for storing lnav's configuration. If you have an existing
~/.lnav directory, that will continue to be used until you move it to
$XDG_CONFIG_HOME/lnav or ~/.config/lnav.
* Removed the ':save-config' command. Changes to the configuration are now
immediately saved.
Fixes:
* Added 'notice' log level.
* If a "timestamp-format" is used in an element of a "line-format", the
field name is ignored and a formatted timestamp is always used.
* Ignore stdin when it is connected to /dev/null.
lnav v0.8.5:
Features:
* Added a visual filter editor to make it easier to update existing
filters. The editor can be opened by pressing TAB. Once the editor
is opened, you can create/delete, enable/disable, and edit the patterns
with hotkeys.
* Added an 'lnav_view_filters' SQL table that can be used to
programmatically manipulate filters.
* Added an 'lnav_view_filter_stats' SQL table that contains the number of
times a given filter matched a line in the view.
* Added a 'log_filters' column to log tables that can be used to see what
filters matched the log message.
* A history of locations in a view is now kept so that you can jump back
to where you were previously using the '{' and '}' keys. The location
history can also be accessed through the ":prev-location" and
":next-location" commands.
* The ":write-*" commands will now accept "/dev/clipboard" as a file name
that writes to the system clipboard.
* The ":write-to" and ":write-raw-to" commands will now print out comments
and tags attached to the lines.
* Added a ":redirect-to <path>" command to redirect command output to the
given file. This command is mostly useful in scripts where one might
want to redirect all output from commands like ":echo" and ":write-to -"
to a single file.
* If a log file format has multiple patterns for matching log messages,
each pattern is now tried to match a message in a file. Previously,
only one pattern was ever used for an entire file.
* Added haproxy log format from Peter Hoffmann.
* Added 'spooky_hash()' and 'group_spooky_hash()' SQL functions to
generate a hash of their parameters.
* Added 'time_offset' to the 'lnav_file' table so that the timestamps in
a file can be adjusted programmatically.
Interface Changes:
* The auto-complete behavior in the prompt has been modified to fall back
to a fuzzy search if the prefix search finds no matches. For example,
typing in ":fin" and pressing TAB would previously not do anything.
Now, the ":fin" will be completed to ":filter-in " since that is a
strong fuzzy match. If there are multiple matches, as would happen
with ":dfil", readline's menu-complete behavior will be engaged and
you can press TAB cycle through the options.
* Added CTRL+F to toggle the enabled/disabled state of all filters for the
current view.
* The '-r' flag is now for recursively loading files. The functionality
for loading rotated files is now under the '-R' flag.
* The current search term is now shown in the bottom status bar.
* Some initial help text is now shown for the search and SQL prompts to
refresh the memory.
* When entering the ":comment" command for a line with a comment, the
command prompt will be filled in with the existing comment to make
editing easier.
* Hidden fields now show up as a unicode vertical ellipsis (⋮) instead of
three-dot ellipsis to save space.
* Pressing 7/8 will now move to the previous/next minute.
* The ":write-raw-to" command has been changed to write the entire
contents of the current view and a ":write-screen-to" command has been
added to write only the current screen contents.
* Disabled filters are now saved in sessions.
* The ":adjust-log-time" command now accepts relative times as input.
Fixes:
* The ":write-json-to" command will now pass through JSON cells as their
JSON values instead of a JSON-encoded string.
lnav v0.8.4:
Features:
* Added the ':comment' command that can be used to attach a comment to a
log line. The comment will be displayed below the line, like so:
2017-01-01T15:30:00 error: computer is on fire
+ This is where it all went wrong
The ':clear-comment' command will remove the attached comment. Comments
are searchable with the standard search mechanism and they are available
in SQL through the "log_comment" column.
* Added the ':tag', ':untag', and ':delete-tags' commands that can be used
to attach/detach tags on the top log line and delete all instances of
a tag. Tags are also searchable and are available in SQL as a JSON
array in the "log_tags" column.
* Pressing left-arrow while viewing log messages will reveal the source
file name for each line and the unique parts of the source path.
Pressing again will reveal the full path.
* The file name section of the top status line will show only the unique
parts of the log file path if there is not enough room to show the full
path.
* Added the ":hide-unmarked-lines" and ":show-unmarked-lines" commands
that hide/show lines based on whether they are bookmarked.
* Added the "json_contains()" SQL function to check if a JSON value
contains a number of a string.
* The relative time parser recognizes "next" at the beginning of the
input, for example, "next hour" or "next day". Handy for use in the
":goto" command.
* Added a "text-transform" option for formatting JSON log messages. The
supported options are: none, uppercase, lowercase, and capitalize.
* Added a special "__level__" field name for formatting JSON messages so
that the lnav level name can be used instead of the internal value in
the JSON object.
* Added a log format for journald JSON logs.
Interface Changes:
* When typing in a search, instead of moving the view to the first match
that was found, the first ten matches will be displayed in the preview
window.
* The pretty-print view maintains highlighting from the log view.
* The pretty-print view no longer tries to reverse lookup IP addresses.
* The online help for commands and SQL functions now includes a 'See Also'
section that lists related commands/functions.
Fixes:
* The HOME key should now work in the command-prompt and move the cursor
to the beginning of the line.
* The :delete-filter command should now tab-complete existing filters.
* Milliseconds can now be used in relative times (e.g. 10:00:00.123)
* The J/K hotkeys were not marking lines correctly when the bottom of
the view was reached.
* The level field in JSON logs should now be recognized by the level
patterns in the format.
lnav v0.8.3:
Features:
* Support for the Bro Network Security Monitor (https://www.bro.org) log
file format.
* Added an fstat() table-valued function for querying the local
filesystem.
* Added readlink() and realpath() SQL functions.
* Highlights specified in log formats can now specify the colors to use
for the highlighted parts of the log message.
* Added a ":quit" command.
* Added a "/ui/default-colors" configuration option to specify that the
terminal's default background and foreground colors should be used
instead of black and white.
Interface Changes:
* Pressing delete at a command-prompt will exit the prompt if there is no
other input.
Fixes:
* The help view now includes all the command-help that would pop up as
you entered commands and SQL queries.
* Hidden fields and lines hidden before/after times are now saved in the
current session and restored.
* Unicode characters should now be displayed correctly (make sure you
have LANG set to a UTF-8 locale).
lnav v0.8.2:
Features:
* The timestamp format for JSON log files can be specified with the
"timestamp-format" option in the "line-format" array.
* Added "min-width", "max-width", "align", and "overflow" options to the
"line-format" in format definitions for JSON log files. These options
give you more control over how the displayed line looks.
* Added a "hidden" option to log format values so that you can hide JSON
log fields from being displayed if they are not in the line format.
* Added a "rewriter" field to log format value definitions that is a
command used to rewrite the field in the pretty-printed version of a
log message. For example, the HTTP access log format will rewrite the
status code field to include the textual version (e.g. 200 (OK)).
* Log message fields can now be hidden using the :hide-fields" command or
by setting the 'hidden' property in the log format. When hidden, the
fields will be replaced with a yellow ellipsis when displayed. Hiding
large fields that contain extra details can make the log easier to read.
The 'x' hotkey can be used to quickly toggle whether these fields are
displayed or not.
* Added a ':mark' command to bookmark the top line in the current view.
* Added an ':alt-msg' command that can be used to set the text to be
displayed in the bottom right of the command line. This command is
mostly intended for use by hotkey maps to set the help text.
* In lnav scripts, the first row of a SQL query result will now be turned
into local variables that can be referenced in other commands or
queries. For example, the following script will print the number one:
;SELECT 1 as foobar
:eval :echo ${foobar}
* Added an 'lnav_view_stack' SQL table that gives access to the view
stack.
* Added a 'top_time' column to the lnav_views table so that you can get
the timestamp for the top line in views that are time-based as well as
allowing you to move the view to a given time with an UPDATE statement.
* Added a 'search' column to the lnav_views table so that you can perform
a text search programmatically.
* Added a 'regexp_capture(<string>, <pattern>)' table-valued function for
getting detailed results from matching a regular expression against a
string.
* Added a 'timediff(<time1>, <time2>)' SQL function for computing the
difference between two relative or absolute timestamps.
* Log formats can now define a default set of highlights with the
"highlights" property.
* Added a '|search-for <pattern>' built-in script that can be used to
start a search from the command-line.
* Log format definitions can now specify the expected log level for a
sample line. This check should make it easier to validate the
definition.
Interface Changes:
* Command and SQL documentation is now displayed in a section at the
bottom of the screen when a command or query is being entered. Some
commands will also display a preview of the command results. For
example, the ':open' command will display the first ten lines of the
file to be opened and the ':filter-out' command will highlight text
that matches in the current view. The preview pane can be shown/hidden
by pressing CTRL-P.
* The color used for text colored via ":highlight" is now based on the
the regex instead of randomly picked so that colors are consistent
across invocations.
* The "graph" view has been removed since it's functionality has been
obsoleted by other features, like ":create-search-table".
* When doing a search, if a hit is found within a second after hitting
<ENTER>, the view will move to the matched line. The previous behavior
was to stay on the current line, which tended to be a surprise to new
users.
* Pressing 'n'/'N' to move through the next/previous search hit will now
skip adjacent lines, up to the vertical size of the view. This should
make scanning through clusters of hits much faster. Repeatedly
pressing these keys within a short time will also accelerate scanning
by moving the view at least a full page at a time.
Breaking Changes:
* The captured timestamp text in log files must fully match a known format
or an error will be reported. The previous behavior was to ignore any
text at the end of the line.
Fixes:
* You can now execute commands from the standard input by using a dash (-)
with the '-f' command-line argument. Reading commands from a file
descriptor should also work, for example, with the following bash
syntax:
$ lnav -f <(echo :open the-file-to-open)
* Programming language syntax highlighting should now only be applied to
source code files instead of everywhere.
lnav v0.8.1:
Features:
* Added a spectrogram command and view that displays the values of a
numeric field over time. The view works for log message fields or
for database result columns.
* Log formats can now create SQL views and execute other statements
by adding '.sql' files to their format directories. The SQL scripts
will be executed on startup.
* Added 'json_group_object' and 'json_group_array' aggregate SQL
functions that collects values from a GROUP BY query into a JSON
object or array, respectively.
* The SQL view will now graph values found in JSON objects/arrays in
addition to the regular columns in the result.
* Added an 'regexp_match(<re>, <str>)' SQL function that can be used to
extract values from a string using a regular expression.
* Added an 'extract(<str>)' SQL function that extracts values using the
same data discover/extraction parser used in the 'logline' table.
* Added a "summary" overlay line to the bottom of the log view that
displays how long ago the last message was received, along with the
total number of files and the error rate over the past five minutes.
* Pressing 'V' in the DB view will now check for a column with a
timestamp and move to the corresponding time in the log view.
* Added 'a/A' hotkeys to restore a view previously popped with 'q/Q'.
* Added ":hide-lines-before", ":hide-lines-after", and
":show-lines-before-and-after" commands so that you can filter out
log lines based on time.
* Scripts containing lnav commands/queries can now be executed using
the pipe ('|') hotkey. See the documentation for more information.
* Added an ":eval" command that can be used to execute a command or
query after performing environment variable substitution.
* Added an ":echo" command that can be useful for scripts to message
the user.
* The "log_part" column can now be set with an SQL UPDATE statement.
* Added a "log_body" hidden column that returns the body of the log
message.
* Added ":config", ":reset-config", and ":save-config" commands to change
configuration options, reset to default, and save them for future
executions.
* Added a "/ui/clock-format" configuration option that controls the time
format in the top-left corner.
* Added a "/ui/dim-text" configuration option that controls the brightness
of text in the UI.
* Added support for TAI64 timestamps (http://cr.yp.to/libtai/tai64.html).
* Added a safe execution mode. If the 'LNAVSECURE' environment variable is
set before executing lnav, the following commands are disabled:
- open
- pipe-to
- pipe-line-to
- write-*-to
This makes it easier to run lnav with escalated privileges in restricted
environments, without the risk of users being able to use the above
mentioned commands to gain privileged access.
Interface Changes:
* The 'o/O' hotkeys have been reassigned to navigate through log
messages that have a matching "opid" field. The old action of
moving forward and backward by 60 minutes can be simulated by
using the ':goto' command with a relative time and the 'r/R'
hotkeys.
* Log messages with timestamps that pre-date previous log messages will
have the timestamp highlighted in yellow and underlined. These out-
of-time-order messages will be assigned the time of the previous
message for sorting purposes. You can press the 'p' hotkey to examine
the 'Received Time' of the message as well as the time parsed from the
original message. A "log_actual_time" hidden field has also been
added to the SQLite virtual table so you can operate on the original
message time from the file.
* The 'A/B' hotkeys for moving forward/backward by 10% line increments
have been reassigned to '[' and ']'. The 'a' and 'A' hotkeys are now
used to return to the previously popped view while trying to preserve
the time range. For example, after leaving the spectrogram view with
'q', you can press 'A' return to the view with the top time in the
spectrogram matching the top time in the log view.
* The 'Q' hotkey now pops the current view off of the stack while
maintaining the top time between views.
Fixes:
* Issues with tailing JSON logs have been fixed.
* The jget() SQL function should now work for objects nested in arrays.
lnav v0.8.0:
Features:
* Integration with "papertrailapp.com" for querying and tailing
server log and syslog messages. See the Papertrail section in
the online help for more details.
* Remote files can be opened when lnav is built with libcurl v7.23.0+
* SQL queries can now be done on lines that match a regular expression
using the "log_search" table or by creating custom tables with the
":create-search-table" command.
* Log formats that are "containers" for other log formats, like
syslog, are now supported. See the online help for more
information.
* Formats can be installed from git repositories using the '-i' option.
A standard set of extra formats can be installed by doing
'lnav -i extra'. (You must have git installed for this to work.)
* Added support for 'VMware vSphere Auto Deploy' log format.
* Added a 'sudo' log format.
* Added hotkeys to move left/right by a smaller increment (H/L or
Shift+Left/Shift+Right).
* A color-coded bar has been added to the left side to show where
messages from one file stop and messages from another file start.
* The '-C' option will now try to check any specified log files to
make sure the format(s) match all of the lines.
* Added an "all_logs" SQLite table that contains the message format
extracted from each log line. Also added a ';.msgformat' SQL command
that executes a query that returns the counts for each format and the
first line where the format was seen.
* Added an "lnav_views" SQLite table that can be used to query and
change the lnav view state.
* When typing in a command, the status bar will display a short
summary of the currently entered command.
* Added a "delete-filter" command.
* Added a "log_msg_instance" column to the logline and log_search
tables to make it easier to join tables that are matching log
messages that are ordered.
* Added a "timeslice()" function to SQLite so that it is easier to
group log messages by time buckets.
* The 'goto' command now supports relative time values like
'a minute ago', 'an hour later', and many more.
Interface Changes:
* The 'r/R' hotkeys have been reassigned to navigate through the log
messages by the relative time value that was last used with the
'goto' command.
Fixes:
* The pretty-print view should now work for text files.
* Nested fields in JSON logs are now supported for levels, bodies, etc...
* Tab-completion should work for quoted SQL identifiers.
* 'lo-fi' mode key shortcut changed to CTRL+L.
* 'redraw' shortcut removed. Relegated to just a command.
* Fixed lnav hang in pretty-print mode while doing a dns lookup.
* The generic log message parser used to extract data has been
optimized and should be a bit faster.
lnav v0.7.3:
Features:
* Add 'pipe-to' and 'pipe-line-to' commands that pipe the currently
marked lines or the current log message to a shell command,
respectively.
* Added a "pretty-print" view (P hotkey) that tries to reformat log
messages so that they are easier to read.
* Added a 'redraw' command (CTRL+L hotkey) to redraw the window in
case it has been corrupted.
* Added a 'relative-goto' command to move the current view relative
to its current position.
* Experimental support for linking with jemalloc.
* The plain text view now supports filtering.
* Added 'next-mark' and 'prev-mark' commands to jump to the next or
previous bookmarked line (e.g. error, warning, ...)
* Added a 'zoom-to' command to change the zoom level of the histogram
view.
* Log formats can now define their own timestamp formats with the
'timestamp-format' field.
Fixes:
* Autotools scripts overhaul.
* Added a configure option to disable linking with libtinfo. The newer
versions of ncurses don't require it, however the build silently pulls
it in as a dependency, if it is available on the system. This can be
explicitly disabled using the '--disable-tinfo' option during configure.
* Fixed the configure script behavior to ignore the values specified using
the CFLAGS and LDFLAGS environment variables while searching for sqlite3
when '--with-sqlite3' switch was specified without the prefix.
* The configure script now recognizes libeditline symlink'ed to masquerade
as libreadline. This previously used to cause problems at compile time,
specially on OS X. If you come across this error, use the
'--with-readline=prefix' switch to specify the path to the correct
location of libreadline.
* The order that log formats are tried against a log file is now
automatically determined so that more specific formats are tested
before more general ones. The order is determined on startup based on
how each format matches each other formats sample lines.
* Command files (i.e. those executed via the '-f' flag) now support
commands/queries that span more than one line.
* Added more log levels: stats, debug2 - debug5.
lnav v0.7.2:
* Added log formats for vdsm, openstack, and the vmkernel.
* Added a "lo-fi" mode (L hotkey) that dumps the displayed log lines
to the terminal without any decorations. The write-to, write-json-to,
and write-csv-to commands will also write their output to the terminal
when passed '-' as the file name. This mode can be useful for copying
plain text lines to the clipboard.
* (OS X) Text search strings are copied to the system's "find" clipboard.
Also, when starting a new search, the current value in the "find"
clipboard can be tab-completed.
lnav v0.7.1:
Features:
* Added an 'environ' SQL table that reflects lnav's environment
variables. The table can be read and written to using SQL
SELECT, INSERT, UPDATE, and DELETE statements. Setting variables
can be a way to use SQL query results in lnav commands.
* Added a 'jget' SQLite function that can extract fields from a JSON-
encoded value.
* Added log formats for the OpenAM identity provider.
* Added a 'clear-highlight' command to clear previous calls to the
'highlight' command.
* Fixed some performance bugs in indexing JSON log formats. Loading
times should be at least five times faster.
* Filtering performance should be improved so that enabling/disabling
filters should be almost instantaneous.
* The filter-in, filter-out, and highlight commands now support
tab-completion of text in the current view.
* Add a '-i' flag that installs format files in: ~/.lnav/formats/installed
lnav v0.7.0:
Features:
* Add the '.schema' SQL command to open a view that displays the schema
for the internal tables and any attached databases. If lnav was only
executed with a SQLite database and no text files, this view will open
by default.
* The scroll bar now indicates the location of errors/warnings, search
hits, and bookmarks.
* The xterm title is update to reflect the file name for the top line
in the view.
* Added a "headless" mode so that you can execute commands and run SQL
queries from the command-line without having to do it from the curses
UI.
* When doing a search or SQL query, any text that is currently being
displayed can be tab-completed.
* The '-H' option was added so you can view the internal help text.
* Added the 'g/G' hotkeys to move to the top/bottom of the file.
* Added a 'log_mark' column to the log tables that indicates whether or
not a log message is bookmarked. The field is writable, so you can
bookmark lines using an SQL UPDATE query.
* Added syntax-highlighting when editing SQL queries or search regexes.
* Added a "write-json-to" command that writes the result of a SQL query
to a JSON-formatted file.
* The "elapsed time" column now uses red/green coloring to indicate
sharp changes in the message rate.
* Added a "set-min-log-level" command to filter out log messages that
are below a given level.
Fixes:
* Performance improvements.
* Multi-line filtering has been fixed.
* A collator has been added to the log_level column in the log tables
so that you can write expressions like "log_level > 'warning'".
* The log_time datetime format now matches what is returned by
"datetime('now')" so that collating works correctly.
* If a search string is not valid PCRE syntax, a search is done for
the exact string instead of just returning an error.
* Static-linking has been cleaned up.
* OpenSSL is no longer a requirement.
* Alpha support for Windows/cygwin.
* Environment variables can now be accessed in SQL queries using
the syntax: $VAR_NAME
* An internal log is kept and written out on a crash.
* Partition bookmarks are now tracked separately from regular user
bookmarks. You can start a partition with the 'partition-name'
command and remove it with the 'clear-partition' command.
* Improved display of possible matches during tab-completion in the
command-prompt. The matches are now shown in a separate view and
pressing tab repeatedly will scroll through the view.
* The "open" command now does shell word expansion for file names.
* More config directory paths have been added: /etc/lnav,
$prefix/etc/lnav, and directories passed on the command-line with -I.
lnav v0.6.2:
Features:
* Word-wrap support.
Fixes:
* Fix some OS X Mavericks build/runtime issues.
lnav v0.6.1:
Features:
* Support for JSON-encoded log files.
Fixes:
* Some minor fixes and performance improvements.
lnav v0.6.0:
Features:
* Custom log formats and more builtin formats
* Automatic extraction of data from logs
* UI improvements, support for 256 color terminals
lnav v0.5.1:
Features:
* Added the '-t' and '-w' options which can be used to prepend a
timestamp to any data piped in on stdin and to specify a file to
write the contents of stdin to.
Fixes:
* Cleanup for packaging.
lnav v0.5.0:
Features:
* Files can be specified on the command-line using wildcards so that
new files are automatically loaded. Directories can also be passed
as command-line arguments to read all of the files in the directory.
* Builds on cygwin again.
* Added the 'C' hotkey to clear any existing user bookmarks.
* Added experimental support for accepting input from mice.
Fixes:
* Internal cleanup.
* Copying to the clipboard on OS X is now supported.
* Many bug fixes.
lnav v0.4.0:
Features:
* Files that are not recognized as containing log messages have been
broken out to a separate text files view. You can flip between the
log view and the text file view with the 't' hotkey. When viewing
text files, the 'f' hotkey will switch between files.
* Files compressed with bzip2 are recognized and decompressed on the
fly.
* Added a "session" file and command for storing commands that should
be executed on startup. For example, if you always want some
highlighting to be done, you can add that command to the session
file.
Fixes:
* Add some more log file formats for generic log files.
* Performance improvements for compressed files.
* Works on OS X now.
lnav v0.3.0:
Changes:
* The hotkey for the SQL view was changed to 'v' and 'V' from '.'.
Features:
* You can now switch between the SQL result view and the log view while
keeping the top of the views in sync with the "log_line" column.
Fixes:
* The "log_line" column is no longer included in the SQL result view's
stacked bar graph.
* Added a "warnings" count to the histogram view.
