Log file

10:57:10[DEBUG] Running formatters on test.R: { "styler" }
10:57:10[INFO] Run styler on test.R
10:57:10[DEBUG] Creating temp file .conform.7244551.test.R
10:57:10[DEBUG] Run command: { "R", "-s", "-e", "r.nvim::format()", "--args", ".conform.7244551.test.R" }
10:57:10[DEBUG] styler exited with code 0
10:57:10[DEBUG] Cleaning up temp file .conform.7244551.test.R

Describe the bug

1. Formatting R code has no effect

2. r.nvim is working, and the command line that conform.nvim is trying to run is working as well:

➜ # see minimal example file for test.R
➜ R -s -e "r.nvim::format()" --args ./test.R
df <- function(a, b) {
	print("ciao")
	c <- a + b
	print(paste0(c))
}

3. Different from "styler" fails to format R/Rmd files #242, in which the error message says that r.nvim is not installed

What is the severity of this bug?

breaking (some functionality is broken)

Steps To Reproduce

See above

Expected Behavior

R code should be formatted, code inside function should be indented

Minimal example file

df <- function(a,b) {
print("ciao")
c = a+b
print(paste0(c))
}

Minimal init.lua

-- conform.nvim
require("conform").setup({
	-- Set the log level. Use `:ConformInfo` to see the location of the log file.
	log_level = vim.log.levels.DEBUG,
	formatters = {
		isort = {
			command = "/usr/bin/isort",
		},
		black = {
			command = "/usr/bin/black",
		},
	},
	formatters_by_ft = {
		python = { "isort", "black" },
		lua = { "stylua" },
		-- styler requires installing the R package `r.nvim` in R
		-- Open R and execute `remotes::install_github("devOpifex/r.nvim")`
		r = { "styler" },
	},
})

vim.api.nvim_create_user_command("ConformFormat", function(args)
	local range = nil
	if args.count ~= -1 then
		local end_line = vim.api.nvim_buf_get_lines(0, args.line2 - 1, args.line2, true)[1]
		range = {
			start = { args.line1, 0 },
			["end"] = { args.line2, end_line:len() },
		}
	end
	require("conform").format({ async = true, lsp_fallback = false, range = range })
end, { range = true })

vim.api.nvim_set_keymap("n", "<Leader>r", ":ConformFormat<CR>", { noremap = true })

Quick workaround:

Create rprettify:

#!/usr/bin/env sh
cp "$1" "$1".bak
R --quiet --no-echo -e "styler::style_file(\"$1\")" 1>/dev/null 2>&1
cat "$1"

Use this config:

	formatters = {
		rprettify = {
			inherit = false,
			command = "rprettify",
			args = { "$FILENAME" },
		},
	},
	formatters_by_ft = {
		r = { "rprettify" },
	},

@6801318d8d solution did not work for me (on save). It seemed to try to format the old save file without your newest changes, instead of saving your changes to the file and then applying formatting. This meant that all changes since last save would disappear.

I got it to work by adding stdin = false to the formatters option.

	formatters = {
		rprettify = {
			inherit = false,
                        stdin = false,
			command = "rprettify",
			args = { "$FILENAME" },
		},
	},
	formatters_by_ft = {
                rmd = { "rprettify" },
		r = { "rprettify" },
	},

The rprettify script can then be simplified to:

R --quiet --no-echo -e "styler::style_file(\"$1\")" 1>/dev/null 2>&1

I guess you should be able to just copy and paste this command into the above formatter, but I did not test that.

I actually prefer this solution over having to rely on another r package, so I will keep it personally.

Do you see any error in the logs? I'm confused as to what is going wrong

[tweakyTweeter]

I had the same error as OP. The solution provided by @BlackEdder worked for me!
