Running Pluto without Webbserver.jl?

[zahachtah]

I love Pluto, it's become my one and only way to write Julia code.

Out of curiosity, and with a possible useful implementation in mind (interacting with notebooks via a remote database), would it be possible to use Pluto without the webserver and pluto-frontend? If I had another Julia process, could I send cell-changes directly and Retrieve the results without going over websockets/http? Where would I best interface the code to achieve this?

process_ws_message seems like one function one could "hijack" for incoming messages, but where would I find updates after code is evaluated? is that in the client channels? Which function makes sure to send them back? I have been digging but Pluto has a biiig codebase now!

I'd like to keep as much as possible of Pluto functionality, its a fantastic piece of work, I'd just like to see if it can be used in a different way. Any hints would be most welcome!

You can try to control notebooks using the internal Julia API. See some of the tests for an example:

Pluto.jl/test/React.jl

Lines 16 to 40 in 4758c4e

	notebook = Notebook([
	Cell("x = 1"),
	Cell("y = x"),
	Cell("f(x) = x + y"),
	Cell("f(4)"),
	Cell("""begin
	g(a) = x
	g(a,b) = y
	end"""),
	Cell("g(6) + g(6,6)"),
	Cell("import Distributed"),
	Cell("Distributed.myid()"),
	])
	fakeclient.connected_notebook = notebook
	@test !haskey(WorkspaceManager.workspaces, notebook.notebook_id)
	update_run!(🍭, notebook, notebook.cells[1:2])
	@test notebook.cells[1].output.body == notebook.cells[2].output.body
	@test notebook.cells[1].output.rootassignee == :x
	@test notebook.cells[1].runtime !== nothing
	setcode!(notebook.cells[1], "x = 12")
	update_run!(🍭, notebook, notebook.cells[1])

Perfect, thanks!
