Do you ever have a terminal watching logs or recompiling on save and you aren't sure if the most recent messages are from the change you just made, or 10 minutes ago? watchlog will help you but adding a message at the bottom of your terminal that haven't produced output recently. After a short period of no output watchlog will start displaying the time since last output below the command.
HTTP/1.1 GET /api/books/1 500 HTTP/1.1 GET /api/books/2 500 HTTP/1.1 GET /api/books/1 500 HTTP/1.1 GET /api/books/1 200 Last output 48s ago.
When the command produces more output it will look like normal if it hasn't been too long, however if it has been a while watchlog will inject a timestamp so that the logs are grouped by when they occurred when you scroll up.
A demo at 6x speed.
Simply put | wl after your command.
sh
$ python -m http.server | wl
watchlog can be configured with watchlog/config.ini. This file will be read from all of the appropriate places for your platform. For example on a Linux system it will be looked for in ~/.config/watchlog and /etc/xdg/watchlog (or whatever you have configured in $XDG_CONFIG_DIRS). If multiple files are found they will be merged according to precedence. If a value is not set in any config file a builtin default will be used.
The following options are supported, the first example for each option shows the default value.
Enable watchlog when there is no output for this long.
ini
delay = 10s
Insert a permanent timestamp into the output after a delay of at least this long.
Note that a timestamp is never inserted after breaks which occur mid-line.
ini
permanent-delay = 30s
ini
permanent-delay = never
Durations can be specified in a simple form with units.
ini
delay = 10s
permanent-delay = 1h 2m 30s
Optional durations can be set to never for an invite duration or a Duration value.
ini
permanent-delay = never
