with EEx.function_from_file I can create a function from an eex-template, call it and get a rendered string back. How can I do that with ~H?

Just when I think: “what a mess, someone should write a macro that automatically loads the templates!” I just didn’t know about that. Very nice, thank you. So the whole thing looks like: defmodule Sample do use Phoenix.Component import MyComponent # sample.html.heex is here embed_templa…

You want to use a separate .heex.html file: to define a component use it instead of ~H in a component? I have not come across an out of box api in phoenix_live_view to achieve the first. If you are looking for second one - there is no straight forward way to do this. [image] …

I want to use ~H as a template engine to create an HTML file (which I can then process with another tool to PDF). I already have these templates working in a liveview-app, but need some of the views as PDF. I was hoping I’d find an equivalent to EEx — EEx v1.21.0-dev - example: # sample.html.heex <…

You can pipe the %Phoenix.LiveView.Rendered into Phoenix.HTML.Safe.to_iodata() |> to_string() which would return the html resulting string.

indeed. Some times things are so obvious :melting_face: defmodule Sample do require EEx EEx.function_from_file( :def, :sample, "sample.html.heex", [:assigns], engine: Phoenix.LiveView.HTMLEngine) end defmodule MyComponent do use Phoenix.Component def greet(assigns) do ~H""" <p…

this (obviously) needs liveview in deps! Which is enough though, no other deps needed (Jason if you want LV to stop complaining) defp deps do [ {:jason, "~> 1.3.0"}, # recommended by LV {:phoenix_live_view, "~> 0.17.10"} ] end writing to a file does not need to_string Samp…

This does not work with LV 0.18, any ideas what to do? == Compilation error in file lib/sample.ex == ** (KeyError) key :caller not found in: [file: "lib/sample.ex", line: 23, engine: Phoenix.LiveView.HTMLEngine] (elixir 1.14.2) lib/keyword.ex:595: Keyword.fetch!/2 (phoenix_live_view 0.18.11…

maybe related to this issue try EEx.function_from_file( :def, :sample, "sample.eex", [:assigns], engine: Phoenix.LiveView.HTMLEngine, caller: __ENV__)

adding caller: __ENV__ leads to the next error: == Compilation error in file lib/sample.ex == ** (KeyError) key :source not found in: [file: ...

I don’t really understand why this is necessary, but this should work: source = "sample.eex" EEx.function_from_file( :def, :sample, source, [:assigns], engine: Phoenix.LiveView.HTMLEngine, caller: __ENV__, source: source)

Couldn’t you just pass HTMLEngine in the options as engine?
