## Trigger off of Lektor events
Plugins have handlers which are attached to *events* emitted by Lektor's core,
or emitted by other plugins. To attach to an event, the plugin needs to have a
method that's named `on_<event>`, where `<event>` is the event's name with
underscores instead of hyphons.
Events can pass arguments through to handlers in a payload, and handlers should
always accept an `**extra` argument to accomodate future expansion of the
payload.
The following is the list of all events emitted by Lektor:
- `setup-env`: Sent while setting up the environment, after all plugins have
been instantiated. This is a good place to change values stored on the
environment.
- `before-prune`, `after-prune`: Sent before and after cleaning up all data in
the build folder that does not correspond to known artifacts.
- `before-build`, `after-build`: Sent before and after building a source
object. These each get sent once for each source object in the build.
- `before-build-all`, `after-build-all` Sent before and after the build
step. These get sent just once for the entire build process.
- `server-spawn`: Sent right after `lektor server` starts its background
server process.
- `server-stop`: Sent right after `lektor server`'s background server process
is stopped.
- `process-template-context`: Sent before processing a template, but after
loading defaults for the template. This is a good place to add things to the
Jinja environment like filters.
- `markdown-config`: Sent right after Lektor's Markdown processor is
configured. The `MarkdownConfig` that is getting set up is passed in, so
this is a good place to add mixins to change the behavior of the Markdown
processor.
- `markdown-meta-init`: Sent right before Lektor's Markdown processor parses
text to convert it into HTML.
- `markdown-meta-postprocess`: Sent right after Lektor's Markdown processor
parses text to convert it into HTML.
## Configure Plugins
Plugins can come with their own config files and it's encouraged that plugins
