# Server.clients(where:)

- **Module:** Server

- **Kind:** method

```
Server.clients(where:)(where: FilterExpr<Client>) -> [Client]
```

Clients matching `expression`.

The one listing here that does not push its filter to tmux. `-f` reached
`list-clients` in tmux 3.4, three releases after this package's floor,
and asking an older server for it fails the whole listing rather than
being ignored. Version-gating it would buy nothing worth the round trip:
a server has one client per attachment, so there is no long list to
narrow. The expression is applied here, and the answer is the same.

## Raises

- `FilteredListingError`
