good point -- i did that, and i also renamed the file to vnd.rkward.r.xml, which makes it a vendor-specific MIME type declaration. that makes it possible for us to define that MIME type without colliding with other packages doing the same. the original XML file is now being installed to /usr/share/mime/packages, but XDG does also automatically generate /usr/share/mime/text/r.xml and /usr/share/mime/application/rdata.xml from it. in effect it's the same result. > I'm still somewhat worried about future clashes. _If_ R ever decides to > start shipping these mime-types, RKWard is going to get the blame for > conflicting names, I'm afraid. i hope this is solved for good now. the hint to libreoffice.xml was useful and led me to the vnd.* files. i'll try and test if this and the protocol handler also works on OS X. can you check that on windows? > > and if you click on an *.RData file, you're asked *once* whether the > > workspace should be saved -- after that, the current worspace is just > > silently replaced with the content of any other RData file you click. > > I changed that a bit, and yes, it might be buggy, but I think you should > find, the behavior is now: > - If a workspace has just been loaded, and not been touched, don't ask > whether to save it before quitting / replacing it. > - If you touch some object in between, you should be prompted, again. right, i missed that part -- i was just baffled that rkward switched from one workspace to another without asking, and i was wondering what that would do to one's data if you accidentally clicked on a *.RData file... but that's a good solution now. > - Now as to why you're prompted for the initial - probably empty - > workspace: It's that .Random.seed that gets created some time in the middle > of starting up. Did not think up a nice way to cope with that, yet. actually, that is something that has always annoyed me a bit: i start RKWard and want to *open* a previous workspace, but the first thing i get is a question whether to *save* the workspace. good thing if that was gone. do we have to care for that single .Random.seed object when one wants to open another workspace anyway? > > single objects can't be added to the workspace this way either. there > > should probably be two methods for handling *.RData files: complete > > workspace or individual R objects, > > True. KDE knows this as service menus, i can try to write an according *.desktop file as well. then you'd have to actively open the file via right click. that would need another option for the rkward binary. alternatively, RKWard could ask you how to deal with the input: replace current workspace or add all objects to the current one. do you know whether there's a difference between *.RData files containing saved workspaces and saved R objects? if there was, we could add a <magic> section to the MIME type, which would cause the first bits of a file to be read to get its type. > > and you should always be asked before > > your workspace is wiped. > > Really? no, its fine as it is (except maybe for the initial workspace). viele grüße :: m.eik -- dipl. psych. meik michalke institut f"ur experimentelle psychologie abt. f"ur diagnostik und differentielle psychologie heinrich-heine-universit"at d-40204 d"usseldorf
