Shinymod snippet incorrect?

[AlbertRapp]

Hi all,

just a silly little thing I noticed. The RStudio shinymod snippet gives us

nameUI <- function(id) {
  ns <- NS(id)
  tagList(
  
  )
}

nameServer <- function(id) {
  moduleServer(
    id,
    function(input, output, session) {
      
    }
  )
}

whereas Positron gives us

name_UI <- function(id) {
  ns <- NS(id)
  tagList(
  
  )
}

name <- function(input, output, session) {
  
}

Is this correct? Do R-Shiny modules not require moduleServer() anymore? 🫨

Also, how do I change the default snippets? I'd like to have my server functions also use the naming convention _Server (just like in RStudio). I tried to create an R snippets file via the command palette but I always end up at a blank fresh snippet file. Where do I find the default snippets? 🤔

I believe this comes from the Shiny extension. I just tried locally and I get the same as your top example.

nameUI <- function(id) {
  ns <- NS(id)
  tagList(
    
  )
}

nameServer <- function(id) {
  moduleServer(id, function(input, output, session) {
    
  })
}

What version of the Shiny Extension are you using?

I updated Positron (and then installed the Shiny extension that I didn't have before) and now everything works :) Thanks 🤗

@AlbertRapp You don't happen to have a very old version of Positron, do you? It looks like you might have the version of the shinymod snippet that we removed back in April: posit-dev/ark#780

@jonvanausdeln is correct that the only snippet I see in an up-to-date version of Positron is this one from the Shiny extension: https://github.com/posit-dev/shiny-vscode/blob/344cb8cb3044f765f374b06a50bdcbf252d082a4/snippets/shiny-r.json#L23
