Returns a specification to start this module under a supervisor.

See Supervisor.

Deletes the content from a host.

• server - the PID or name of the process
• slug - the key of the content

Gets html content from a host.

• server - the PID or name of the process
• slug - the key of the content

Gets html content from a host with cache time.

• server - the PID or name of the process
• slug - the key of the content
• time - the modified time to check.

Invoked when the server is started. start_link/3 or start/3 will block until it returns.

args is the argument term (second argument) passed to start_link/3.

Returning {:ok, state} will cause start_link/3 to return {:ok, pid} and the process to enter its loop.

Returning {:ok, state, timeout} is similar to {:ok, state} except handle_info(:timeout, state) will be called after timeout milliseconds if no messages are received within the timeout.

Returning {:ok, state, :hibernate} is similar to {:ok, state} except the process is hibernated before entering the loop. See c:handle_call/3 for more information on hibernation.

Returning {:ok, state, {:continue, continue}} is similar to {:ok, state} except that immediately after entering the loop the c:handle_continue/2 callback will be invoked with the value continue as first argument.

Returning :ignore will cause start_link/3 to return :ignore and the process will exit normally without entering the loop or calling c:terminate/2. If used when part of a supervision tree the parent supervisor will not fail to start nor immediately try to restart the GenServer. The remainder of the supervision tree will be started and so the GenServer should not be required by other processes. It can be started later with Supervisor.restart_child/2 as the child specification is saved in the parent supervisor. The main use cases for this are:

• The GenServer is disabled by configuration but might be enabled later.
• An error occurred and it will be handled by a different mechanism than the Supervisor. Likely this approach involves calling Supervisor.restart_child/2 after a delay to attempt a restart.

Returning {:stop, reason} will cause start_link/3 to return {:error, reason} and the process to exit with reason reason without entering the loop or calling c:terminate/2.

Callback implementation for GenServer.init/1.

Sets html content to a host with a slug.

• server - the PID or name of the process
• slug - the key of the content
• value - the content to save

Returns :ok.

Sets the content fetcher. A fetcher is used to fetch content from the data source, such as a remote server.

• server - the PID or name of the process
• f - function or module to fetch content

Starts a host.

• opts - options for starting the process

  • name - the process name
  • content_fetcher - the content fetcher for Exhtml.Storage
  • data_dir - the database storage dir for Exhtml.Table
  • data_nodes - the database nodes for Exhtml.Table

Start the repo engine. Before starting a repo, all actions will not be performed and {:error, :repo_not_started} will be returned.

Fetchs and sets the content from the storage to a host’s table.

• server - the PID or name of the process
• slug - the key of the content

Returns content fetched.
