# WslDomain
*Since: 20220319-142410-0fcdea07*
The `WslDomain` struct specifies information about an individual `WslDomain`,
which is used to tell wezterm how to interact with one of your locally
installed [WSL](https://docs.microsoft.com/en-us/windows/wsl/about)
distributions.
By mapping a distribution to a multiplexing domain, wezterm is better able to
support creating new tabs and panes with the same working directory as an
existing tab/pane running in that same domain.
By default, wezterm creates a list of `WslDomain` objects based on parsing the
output from `wsl -l -v` and assigns that as the value of the
[wsl_domains](config/wsl_domains.md) configuration option.
A `WslDomain` is a lua object with the following fields:
```lua
return {
wsl_domains = {
{
-- The name of this specific domain. Must be unique amonst all types
-- of domain in the configuration file.
name = 'WSL:Ubuntu-18.04',
-- The name of the distribution. This identifies the WSL distribution.
-- It must match a valid distribution from your `wsl -l -v` output in
-- order for the domain to be useful.
distribution = 'Ubuntu-18.04',
-- The username to use when spawning commands in the distribution.
-- If omitted, the default user for that distribution will be used.
-- username = "hunter",
-- The current working directory to use when spawning commands, if
-- the SpawnCommand doesn't otherwise specify the directory.
-- default_cwd = "/tmp"
-- The default command to run, if the SpawnCommand doesn't otherwise
-- override it. Note that you may prefer to use `chsh` to set the
-- default shell for your user inside WSL to avoid needing to
-- specify it here
-- default_prog = {"fish"}
},
},
}
```
