Modifications have been made; patch in kern/14087. It produces identical output to the new softcore.pl for my test case of cat sys/boot/ficl/softwords/*.fr People (more) familiar with ficl syntax might like to craft some awkward constructs and check that I'm handling them legally. Note that the script contains one gawk-ism (use of strftime() to include a cosmetic "last update" comment in the generated softcore.c). In my opinion, this should be eliminated -- it seems like a needless GNUism to me. gawk(1) says that the use of the character class [[:space:]] is consistent with POSIX 1003.2 (and I have no reason to disbelieve it). However, [[:space:]] also seems to be frequently misunderstood by other common awks, so it might also be considered a candidate for removal in the interests of portability. The alternative is a bit messier, though, and not necessarily portable across different locales.

Knowing both perl and awk, I like awk a _lot_ better. It is definitely much easier to learn and to use. (You _have_ to learn it first, of course, but if you already know C, you know 90% of awk.) A lot of my scripts begin with #!/usr/bin/awk -f ;) In fact, I learned perl first and did quite a lot of things with it. However, when I became more familiar with awk, the deficiencies of perl became more and more obvious to me. So I started porting my old perl stuff: to sh, to awk, to C, or whatever seemed most appropriate. (I still have some perl scripts left, just because they work, and lack of time to convert, or because someone else wrote them without too much care, rendering them unreadable and unmaintainable -- a common problem with perl.)

I think that's sort of in the grey area. There are also many Hardened Traditionalists(tm) like myself who don't know perl and have no interest in learning it because everything they ever need to do can be handled by sh, awk and sed and they spent many years gaining that level of proficiency with them.

Anyway, all good to know. There are almost certainly more perl speakers than awk speakers these days, so it probably makes sense to do these things in perl rather than awk. However, take care not to underestimate the awesome power of awk. When you come down to it, there's an awful lot of userland that (when you come down to it) does nothing more than interate over each line in an input file :) Joe Abley awk-deconstructionist To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message

It would be very hard, imho, to replace doug's perl scripts with awk ones. However, my knowledge of perl >> awk, so there maybe some awk tricks that would make it easier.

/me wonders how did this got to _not_ be committed.
Well, that's why I wanted some disk space to make a test compilation
of the changes I was about to commit...

Alas, FICL's author, John Sadler, has optimized the perl script. The main reason for using awk instead of perl was removing a world dependency on perl. It seems we are definitely committed to perl nowadays, so it might be better to just use the newer perl script. OTOH, if we are still perl-safe, I could send you the newer perl script, so you can adapt from that. Mike, what would you prefer? -- Daniel C.
