Assuming that can even happen. I'm constantly running into these, because of different people editing using different editors. Usually it's someone else's, where they didn't notice that the published final code looks terrible (obviously not in Python). Is F# a version of Fortran for .Net? :-) (Like A#.) Or is it Forth?

With GNAT and the -gnatyh switch, the compiler will issue a warning if it encounters tabs in source code. Our coding standard "requires" users to set the "convert tabs to spaces" and the "trim trailing spaces" settings in whatever editor they use (usually GPS, GNATbench, or UltraEdit) We also use the ASIS based gnatcheck (coding standard checker) and gnatpp (pretty printer) to check and standardize source code format for our Ada projects. I suspect other languages don't have such good utilities since they have no equivalent to ASIS (that I'm aware of). > > Is F# a version of Fortran for .Net? :-) (Like A#.) Or is it Forth? > Neither.

How about Scheme which, as I understand it, is basically a LISP-decedent/varient developed in response to Common Lisp (which, IIRC, had the commonality of alienating large portions of particular-implementation-X for all implementations).

Thanks to all for the comments. You covered many points that I had long considered benefits (and so...darn...nice!), and some that I hadn't really thought about.

If copyright and the wishes of the performers will permit etc etc. All references I have been able to find (some volumes II + III of accompanying material) point to a two-digit number of video tapes by Alsys from 1984. |
