# `user-var-changed`
|
|
|

The `user-var-changed` event is emitted when a *user var* escape sequence is
|
|
used to set a user var.
|
|
|
|
You can use something like the following from your shell:
|
|
|
|
```bash
|
|
printf "\033]1337;SetUserVar=%s=%s\007" foo `echo -n bar | base64`
|
|
```
|
|
|
|
to set the user var named `foo` to the value `bar`.
|
|
|
|
Then, if you have this in your config:
|
|
|
|
```lua
|
|
local wezterm = require 'wezterm'
|
|
|
|
wezterm.on('user-var-changed', function(window, pane, name, value)
|
|
wezterm.log_info('var', name, value)
|
|
end)
|
|
|
|
return {}
|
|
```
|
|
|
|
your event handler will be called with `name = 'foo'` and `value = 'bar'`.
