major feature:
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:
``lnav.
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

0.12.330 Apr 2024 01:25
minor bugfix:
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.
:
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.
Maintenance:
Upgrade to C++17.
