Hi. WISHLIST: Regardless on console, I'd like to be able to timeout a call to readline()/file("stdin", blocking=TRUE) via setTimeLimit. OBSERVATION: On Windows Rterm as well as plain R on Linux, setTimeLimit() does not momentarily interrupt from stdin, but only after hitting RETURN. A few examples: timeout00 <- function() { setTimeLimit(elapsed=5); Sys.sleep(10); }

Neither do_menu nor do_readln (in src/main/scan.c) call the function InitConsoleGetchar. They need to do this to reset ConsolePrompt. If you use "scan" to read in data from the terminal, then ConsolePrompt is set to "n:" for some integer n and this prompt makes an unwelcome appearance when you use the "menu" or "readline" functions. Incidentally, could we

Dear R developers, I have found the following bug with readline() in R 0.63.3: if you execute the menu-function and then the readline() function, then readline() prompts "Selection:" > a <- readline() hello > a [1] "hallo" > a <- menu(c("a", "b"), title="bitte:") bitte: 1:a 2:b Selection: 2 > a <- readline() Selection:

Dear R-helpers, I've just started playing with getGraphicsEvent() in R, and was wondering if there is a simple way to stop this function waiting for input after a pre-defined time, instead of relying either on a non-NULL value from one of the event handlers or for a user-interrupt for it to halt (as per the R manual). The only way that I've thought of to make this work is using

Hi, Is there currently any way to guarantee that on.exit does not fail to execute the recorded expression because of a user interrupt arriving during function exit? Consider: f <- function() { suspendInterrupts({ on.exit(suspendInterrupts(cntr_on.exit <<- cntr_on.exit + 1L)) cntr_f <<- cntr_f + 1L }) TRUE } It is possible to interrupt this function such that cntr_f

setTimeLimit(elapsed=1) causes a timeout error whenever a call takes more than one second. For instance, this is how it works on Windows (R 3.3.1): > setTimeLimit(elapsed=1) > Sys.sleep(10); message("done") Error in Sys.sleep(10) : reached elapsed time limit Also, the error propagates immediately and causes an interrupt after ~1 second; > system.time({ Sys.sleep(10);

On unix, unless event polling is enabled Sys.sleep just waits in a select() call (with a SIGINT handler in place) so the elapsed time isn't checked until after the select call is complete. Rstudio uses event polling, and in particular sets R_wait_usec to 10000, which means event and interrupt checks happen during a Sys.seep call. The R GUI on macOS doesn't seem to do this (but my lldb

I would like to use setTimeLimit to abort operations that are stuck waiting (idle) after n seconds. Below a toy example in which Sys.sleep is a placeholder call that is idle: testlimit <- function(){ setTimeLimit(elapsed=3, transient=TRUE); Sys.sleep(10); } system.time(testlimit()); However this is giving inconsistent results. On windows and in r-studio server (linux) the call is

Dear friends, In configuring R 2.4.1 for Solaris 11, using SunStudio 11 compilers, I get the following error. checking readline/history.h usability... no checking readline/history.h presence... no checking for readline/history.h... no checking readline/readline.h usability... no checking readline/readline.h presence... no checking for readline/readline.h... no checking for rl_callback_read_char

Thank you for the feedback and confirmations. Interesting to see that it's also reproducible on macOS expect for Spencer; that might indicate a difference in builds. BTW, my original post suggested that timeout error was for sure detected while running Sys.sleep(10). However, it could of course also be that it is only detected after it finishes. For troubleshooting, the

Dear community, I'm trying to install R-2.2.1 on an IRIX 6.2 (Unix System V Release 4) system without root access. Unfortunately readline is not installed in default, so I installed it locally in my home directory, more precisely in: $HOME/vol/readline-5.1, where $HOME is "/home3/fa/faga001". Afterwards I appended the path to the library with several $PATH variable, which now looks

We've recently "upgraded" a server to solaris 8, and in reinstalling R I've encountered a problem in getting it to recognize the readline library. I have installed readline in what I believe to be the "usual" place: /usr/local/lib with include files in /usr/local/include/readline. But ./configure produces: ragnar.econ.uiuc.edu# grep readline hout checking for

Hello! I'm trying to install R-1.9.1a with readline on Suse Linux.

Hi all, I just upgraded to R-1.8.0. Everything worked fine but command line editing does not work. This clearly indicates that readline has not been found in the compilation process. How could I explicitely indicate where to find it ? I use a Red Hat 8.0 system. I checked the FAQ which says readline-devel is also needed, but I have it already installed. Perhaps should I add the configure

Hi. Using Rterm v2.2.1 on WinXP, is there a way to interrupt a call like repeat { readline() } without killing the Command window?

Am trying to install 2.14.0 on a CentOS system. The configure script apparently can't find something to do with the readline library: Configure: error: --with-readline=yes (default) and headers/libs are not available Yes, I know I need readline 4.2 or later. "yum" assures me that rev 5.1 is already installed. And I know I need to provide configuration flags if it is in
