...y very condensed and very simplified version of the code is included below. The program can create plots. However, after the plot is initially drawn it is no longer updated. When scaling or updating the plot the window becomes blank, and the window also doesn't want to close. I suspect that my R_ReadConsole routine is the problem. This routine waits for user input and returns this (which I thought it should). It seems that this causes the event loop that updates the windows to also be on hold. I did have a look at 'Rstd_ReadConsole' in 'src/unix/sys-std.c', but I can't figure out w...

...king for an answer on the WEB and intercepted some pieces of answers ... but I did not succeed in getting a workable solution. This is the reason why I put this open question here today. I did not find lots of information about the gets solution. Finally, I have chosen to use R_WriteConsole and R_ReadConsole which seemed to be promising solutions. I discovered an information saying that starting R-2.0.1, the include file R-interface.h could help me. This is the reason why I downloaded the latest version available on the R site (R-2.2.1). Unfortunately, I did not find such a file in the include dir...

...d I'm not happy with the current REPL, since it prevents any general solution. Are there plans to improve the current REPL anytime soon? The current approach has some deficiencies you are surely aware of (only one input (=external event loop), the loop is blocked while waiting for input in R_ReadConsole, ...). But the major problem is that several packages/modules simply replace the standard REPL with their own implementations by not returning control to the loop. This virtually prevents any cooperation - it is impossible to load two such modules at a time without breaking something. I think...

...--------- > ÿ Save workspace image? [y/n/c]: ---------------------------------------------------------------------------- i.e, 'y diaeresis' seems interpreted as an EOF. I don't know where is the solution but problem seems due to the conversions from int to char (made implicitly by R_ReadConsole) and then back to int made in src/main/gram.y(buffer_getc). Result is that the 'if (c==EOF)' test in that function is true when c='y diaeresis'. Indeed: ---------------------------------------------------------------------------- [~/tmp]% cat a.c #include <stdio.h> int main(...

Now, the gnuplot people has developed a layer between stdio and a windows console (a graphics not a ms-dos one).
