possible to lazy load R.nvim?

[ssh352]

I open an empty buffer and R.nvim plugin is already loaded. However plugins for other programming languages are not loaded if you are not working with them. Could you advise why we need to eager load R.nvim? Thanks!

[jalvesaq]

Because it is a filetype plugin which means that it always was lazy loaded (since 2009, long before Neovim existed). The lazy feature is useful for general plugins.

https://github.com/R-nvim/R.nvim/blob/main/README.md?plain=1#L12 suggests it is eager loaded instead of lazy loaded.

When I start neovim, not editing any R scripts. I found R.nvim is already loaded. I'd want it to lazy load just like other filetype plugins too.

[jalvesaq]

As far as I know, R.nvim is immediately in the path because lazy = false, but the slow setup functions will not run unless you start editing an R file type (R, Rnoweb, Rmd, or Quarto). Moreover, the slowest setup functions run asynchronously and don't affect the startup time.

I'd want it to lazy load just like other filetype plugins too.

Please, do a pull request for this. If it improves R.nvim and the overall Neovim's experience, we will merge it. Alternatively, you can try putting lazy = true in your config and manually configure what will trigger R.nvim setup. I can't give any advice on how to do this because it's something that I have never done, and I'm convinced that it's unnecessary.

What is Neovim's startup time when editing a non-R filetype with R.nvim installed and with it uninstalled?

You can use the command :Lazy profile to answer these questions. Please, report your results here.

[jalvesaq]

On my system, either opening a plain text without file extension or an R script, :Lazy profile reports the same result (about 3 ms):

        ★  start  R.nvim 3ms
          ‒  nvim-autopairs 2.53ms
          ‒  R.nvim/ftdetect/r.lua 0.11ms

But note that the command :RDebugInfo is not available after starting Neovim editing a non-R file which means that the R.nvim setup function was not run. This is what I mean when I say that filetype plugins are natively lazy-loaded. With an R file type, :RDebugInfo outputs:

Time:
  before_rns.R (async): 0.130420534
  global setup: 0.003612362
  check health (async): 0.000355095
  unix setup: 8.504e-06

The slowest config operation is to run the before_rns.R script, but this task is performed asynchronously. That's why :Lazy profile reports the same time to load R.nvim regardless of the file type being R or not.

This is where I thought it is eager loaded, I'll take a close look, Thanks!

Thanks for the details. I'll take a look if I can set lazy=true(which is the default). I am very new to lua and the plugin system though.

I use the Lazyvim distribution. to just start neovim, with R.nvim total startup time is 84ms, without R.nvim is 57ms.

The increase from 57 ms to 84 ms in your system seems to be due to cmp-r (28 ms). However, my total time when starting Neovim editing a simple R file with the global lazy.nvim option lazy = false is:

    LazyStart 8.02ms
    LazyDone  80.67ms (+72.64ms)
    UIEnter   104.41ms (+23.75ms)

and I can't find cmp-r listed in the Lazy profile output.

I added the creation of a temporary global variable to cmp-r setup function and noted that it is created only when I enter Insert mode. So, maybe there is something in your config that is triggering cmp-r setup earlier than necessary.

[ssh352]

setting lazy=true and event = "BufEnter *.R" seem to work for me. what do you think?

[jalvesaq]

In lazy.nvim config, putting these settings in both R.nvim and cmp-r, they don't appear in the Lazy profile output when opening a non-R file, but opening an R script becomes slower and cmp completion doesn't work.

Anyway, note that R.nvim should be enabled not only for R, but also for Rmd, Quarto, Rnoweb, and Rhelp. Moreover, the ftdetect/r.lua script adds additional syntax support for Rhistory, Rout, and Rproj.
