Whenever I include a pipe (%>%) in a ESS R buffer, I start getting the following error repeatedly, with lags that make editing almost impossible:
error in process sentinel: Not enough arguments for format string
Here is a simple example. If I create a buffer with only this function:
f <- function(x) {
x %>% sqrt
}
I get the following error backtrace when doing any edit that buffer (that's after doing M-x toggle-debug-on-error):
Debugger entered--Lisp error: (error "Not enough arguments for format string")
format-message(" Error in cat(\"@@warning: @@\", e) : \n argument 2 (type 'list') cannot be handled by 'cat'\nCalls: esslint ... tryCatch -> tryCatchList -> tryCatchOne -> <Anonymous> -> cat\nIn addition: Warning message:\nIn file(con, \"r\") : cannot open file 'f <- function(x) {\n x %>% sqrt \n}': No such file or directory\nExecution halted\n")

#f(compiled-function (proc event) #<bytecode 0x4307fddd>)(#<process ess-r-flymake> "exited abnormally with code 1\n")
It looks like the whole function is interpreted as a filename. Is this a bug in ESS? It seems unlikely, as this error is annoying enough that others would have reported it. Any idea on how to investigate this further?
