These tutorials are provided to help you learn how **lnav** works
|
||||||
|
without having to install anything. They are running on a shared
|
||||||
|
[fly.io](https://fly.io) instance, so please be kind.
|
||||||
|
|
||||||
|
The tutorials are implemented using features in **lnav** and not
|
||||||
|
built in to the code itself. The tutorial text is
|
||||||
|
[markdown](https://docs.lnav.org/en/latest/ui.html#markdown),
|
||||||
|
the logic is written [SQL](https://docs.lnav.org/en/latest/sqlext.html),
|
||||||
|
and the reactions are triggered through
|
||||||
|
[events](https://docs.lnav.org/en/latest/events.html).
|
||||||
|
|
||||||
|
The source for the tutorials can be found [here](https://github.com/tstack/lnav/tree/master/docs/tutorials).

excerpt: Try lnav without having to install anything

To make it easier to try out **lnav**, I've deployed an ssh-based playground
|
||||||
|
and tutorial. You can SSH as follows to try them out:
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ ssh playground@demo.lnav.org
|
||||||
|
$ ssh tutorial1@demo.lnav.org
|
||||||
|
```
|
||||||
|
|
||||||
|
<script id="asciicast-HiiUMMmRKZh0uCVKm1Uw8WLlw"
|
||||||
|
src="https://asciinema.org/a/HiiUMMmRKZh0uCVKm1Uw8WLlw.js"
|
||||||
|
async>
|
||||||
|
</script>
|
||||||
|
|
||||||
|
The playground has a couple of example logs to play with. The tutorial
|
||||||
|
tries to guide you through the basics of navigating log files with lnav.
|
||||||
|
The server is running on the free-tier of [fly.io](https://fly.io), so
|
||||||
|
please be kind.
|
||||||
|
|
||||||
|
This effort was inspired by the `git.charm.sh` SSH server and by the
|
||||||
|
[fasterthanli.me](https://fasterthanli.me/articles/remote-development-with-rust-on-fly-io)
|
||||||
|
post on doing remote development on fly.io.
