description: Provides an HTTP server interface to TiddlyWiki
Serves a wiki over HTTP.
The listen command uses NamedCommandParameters:
```
--listen [<name>=<value>]...
```
All parameters are optional with safe defaults, and can be specified in any order. The recognised parameters are:
* ''host'' - optional hostname to serve from (defaults to "127.0.0.1" aka "localhost")
* ''path-prefix'' - optional prefix for paths
* ''port'' - port number on which to listen; non-numeric values are interpreted as a system environment variable from which the port number is extracted (defaults to "8080")
* ''credentials'' - pathname of credentials CSV file (relative to wiki folder)
* ''anon-username'' - the username for signing edits for anonymous users
* ''username'' - optional username for basic authentication
