Let me be more specific: I usually prefer to have large script files, split in functions and I mostly work by creating/debuging/modifying one or a couple of functions at a time, which I test by calling them with some params. Now, every time I modify such a function, I have to send its body to the R console and then its call, so that I test it. However, this involves selecting stuff from the script file every time, which gets rather tedious, especially when the function body grows across more than one screen. Therefore, I think would be useful to have a way of defining in the editor window a sort of markers attached to specific lines \(so that they move meaningfully when editing text\) and a special "Send block to the R console" button which automatically sends to R only the defined block. Of course, this block does not have to be continuous... I hope this is a good suggestion and, again, thanks for this amazing work, Dan-- Labels: RKWard user interface --
Logged In: YES user\_id=300591 Originator: NO Hi Dan, thanks for your request. This looks like a reasonable feature addition, although I can't quite imagine how the UI to go with this would work. This particularily hinges on the part about being able to select non-contiguous regions. The problem is being able to specify which region to run. For contiguous regions, this could be as simple, as having a shortcut to run whichever region the cursor is in. For non-contiguous regions, I don't yet see a good way to allow several different regions in the same file \(i.e. have regions A.1, A.2, A.3 and B.1, B.2, where you'd typically want to either run all of A, or all of B, but never all blocks at once\). Do you have something on this in mind? Roland Vollgraf proposed a similar idea a while ago \(only continuous regions, though\), and started working on it. However, I have not heard back from him since more than a month, now. Again, it's probably a useful feature to have \(whatever the details\), but I won't have the time to work on this anytime soon. If - as a C/C++ developer - you would like to look into this yourself, I'd be happy to accept a patch. Main files to look into are rkward/windows/rkcommandeditorwindow\[part\].\[cpp|h\]. You may also be interested in this thread: https://sourceforge.net/mailarchive/forum.php?thread\_id=31467355&forum\_id=12970 , which discusses Roland's proposal, and even has an almost complete patch \(missing some refinements, as discussed in the thread\). Maybe you could build on top of that. Regards Thomas
-- Originally posted by (AT sourceforge.net): ddediu -- Logged In: YES user\_id=1731761 Originator: YES Hi, Thomas I was actually thinking about having a single, let's call it, "run block", but which could span across non-contiguous lines. More specifically, let's say you have the following script file with numbered lines and you allow in the left-hand number & folding margin of the editor to add three new symbols, let's say "<" to mark the begining of a "run block segment", ">" to mark the end of such a thing and "<>" to makr a one-line one. Then, your file could look like: 1 2 < 3 4 > 5 6 <>7 8 < 9 10 11 > 12 13 which means that there is a single "run block" composed of 3 "run block segments": lines 3-5, line 7 and lines 9-12. When the "run block" button would be pressed, no matter where the cursor is in the editor window, the entire block \(i.e., the 3 segments\) are send in sequence to the R console \(i.e., 3-5,7,9-12\). They could represent, let's say, the body of a function \(3-5\), its call \(7\) and a more complex call embedded in something else \(9-12\). Does it make sense? Now, I've never thought about having more than one such "run block", but might be interesting \(I cannot, for the moment, see the utility, but that's my own limitation :\( \). If we agree that this feature is worth, and we also agree on its specs, I could try to implement it :\) Thanks again, Dan
Logged In: YES user\_id=300591 Originator: NO All right, this is now implemented in the KDE 4 port \(to be released as 0.5.0\). It utilizes kate's arbitrary highlighting ranges to automatically expand/contract the blocks as needed \(character based\!\), and to indicate them using a background color. Since this is not available in KDE 3, it's near impossible to backport to the KDE 3 versions of rkward. Six "blocks" are supported. More could easily be realized, technically, but this would make it really hard to differentiate the blocks visually. Blocks can be overlapping and / or nested, although overlaps cannot currently be represented, visually \(would need improvements in kate rendering\). Non-contiguous blocks are not supported for simplicity of code and user interface, but then you can simply use two separate contiguous regions, which should be good enough in most cases, I guess. Shortcuts Alt+Shift+F1-F6 for running the blocks \(yeah, I know, but it's hard to find consequtive shortcut ranges which are not already assigned\).
