Currently, as far as I can see, both input and output fles must be supplied in the 'tests' directory (the input in a '.R' file, and the output in a corresponding '.Rout.save' file.) Often, the '.R' file is redundant, as it could be reconstructed by simply stripping the commands out of the '.Rout.save' file. E.g., the command $ sed -n -e 's/^[>+] //p' ./src/library/stats/tests/nls.Rout.save produces the same R commands as in ./src/library/stats/tests/nls.R
If I've missed something, and this is already supported, my apologies, & please let me know. If indeed this facility is not present, would anyone from the R core group consider an addition to allow '.Rt' (or '.Rt.save') files in the 'tests' directory? These would by just like the '.Rout.save' files, except that no corresponding '.R' file would be required -- the R commands would be extracted from them by simple line processing. Of course, '.R' and '.Rout.save' files could still be used where necessary or preferred. The primary advantage of this change would be to make it easier to add and maintain tests -- only one file would need to be created or changed, and no redundant information would be required. My view is that tests should be as easy as possible to create and maintain, and the current system adds a small amount of unnecessary difficulty. If such an addition would be considered, I would be happy to supply patches to implement it (and test them in a build under Windows & Linux). I have tested a prototype, and it seems pretty simple to add this: as far as I can see, small changes are needed in three files: ./share/make/tests.mk ./src/gnuwin32/fixed/share/tests.mk ./bin/check Please respond with comments/suggestions/corrections/pointing-out-of-gotchas/etc! thanks, Tony Plate ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
