Module B0_show_urlSource

Action and unit execution to show URLs after builds.

Sourcetype url = [
  1. | `Url of B0_url.t
    (*

    *)
  2. | `In of B0_env.dir * B0_std.Fpath.t
    (*

]

The type for dermining the URL to show.

url defines the default URL to show when .show-url is used on a unit without specifying a path.

Sourceval get_url : B0_env.t -> B0_unit.t -> (B0_url.t, string) result

get_url env u performs the logic to get the url for unit u in environment env.

Server keys

Sourceval listen_args : (authority:string -> B0_std.Cmd.t) B0_meta.key

listen_args defines the arguments to specify for how to make the server listen on authority for connections. These arguments are added at the end of the server tool invocation or before a -- token if there is one.

Sourceval timeout_s : int B0_meta.key

timeout_s defines the maximal number of seconds to wait for the server to be connectable before reloading the URL. Defaults to 1s.

.show-url unit

Sourceval unit : B0_unit.t

unit is the .show-url unit.
