Error: Missing quote and others when debugging function called from shiny::runApp()

[rcst]

First of, I'm using Nvim-R since about 8 years as my one and only way to interact with R. Thank you so much for this!

I noticed this error:

line    7:
E115: Missing quote: '/home/eric/documents/[...]/R

Error detected while processing function ROnJobStdout:
line    7:
E116: Invalid arguments for function RDebugJump

(The path in E115 is much longer.)

while working on a Shiny App that I have put as a R package. Notably, I don't get this error, when simply calling a function containing browser().

The function that I'd like to debug via browser() is ./R/server.R (i.e, relative to the R-file from which I call shiny::runApp())

My configuration in ~/.config/nvim/init.vim: Most interestingly, I had set R_debug = 0 and R_dbg_jmp = 0 when I got this error, but that didn't help it go away. I get this error when using Nvim-R from any branch 'master', 'stable' and 'oldstable'.

Any hint, what I can do to avoid it? It's quite annoying.

I can't replicate the issue because I don't use shiny, but nvimcom is no longer sending the jump command to Nvim-R when R is started while R_debug = 0.

[jalvesaq]

I installed shiny. Could you post here an example of code that triggers the bug, please? I added browser() to the beginning of the server() from the RStudio example, but I didn't get the error that you reported.

[jalvesaq]

I can get a similar error with these two R scripts:

ab'cd.R:

nonsense <- function(x) {
    y <- x + 5
    z <- y - 5
    z
}

testD.R:

source("ab'cd.R")
debug(nonsense)
nonsense(9)

[jalvesaq]

I fixed the bug when the file name of the function being sourced includes single quotes, as in my example above (ab'cd.R).

Thanks @jalvesaq for your swift response!

I put together a reproducible example: https://github.com/rcst/nvimr.shiny.repex. While doing so, I found out, that the problem seems to be rooted in the length of absolute working directory.

Nonetheless, I put together an example that resembles the principle folder structure of what I'm working on.

On Debian, I do

cd ~
mkdir -p test/somelongerfoldername/subdirectory-with-dashes/yet.one.more.subdir.with.dots
cd test/somelongerfoldername/subdirectory-with-dashes/yet.one.more.subdir.with.dots
git clone https://github.com/rcst/nvimr.shiny.repex
cd nvimr.shiny.repex
nvim

I open file app.R and start an R session by \rf and execute shiny::runApp(). This gives me the above error messages.

The call of browser() happens in R/server.R.

Can you reproduce it, too?

[jalvesaq]

It might be fixed now...

[rcst]

It is! Thank you :)
