           Summary: Append Enter to Pipe to Terminal
           Product: kate
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kwrite-devel kde org
        ReportedBy: dominic battre de


Version:            (using KDE Devel)
Installed from:    Compiled sources

Executive Summary: I would like the "Pipe to Terminal" command append a \n to the last line.

This is the reasoning behind it:
I am using kate to write scripts for R (http://www.r-project.org/). R runs in the terminal and I want to submit code from the file I am editing to R frequently.

Suppose the R script contains these lines (just some example):
a <- 1:10;
print(a);
print(rev(a));

Now you select the first two lines with the mouse cursor. This selects the following content (... shows what is highlighted):
|a <- 1:10;.........................|
|print(a);                          |
|print(rev(a));                     |
i.e. the \n after "print(a);" is NOT selected.

If I pipe this to the terminal, the last line is NOT executed.

I have attached a patch that introduces a new action which does the same as "Pipe to Terminal" but unconditionally adds one \n. This helps me a lot.

I see the following questions regarding the patch:
- I am not sure whether there should be a second menu item (clutters the menu), but sometimes one might want to pipe only a part of a line (select the "rev(a)" part and pipe this) - a shortcut would be sufficient for me, as I would not use the menu anyway.
- I am not sure what would be the best description for the command ("Pipe to Terminal and auto-confirm with Enter" is somewhat long).
- One could add a configuration option of the plugin that sets whether \n should always be added or never, but that takes the flexibility.
- One might be able to make the "Pipe to Terminal" action smarter: If the end-cursor is located at a EOL, a \n would be added, but I don't know how to do that.
