As far as I know, it is a local idiosyncracy, and my documentation predates it. Thank you for calling it to my attention. It looks like you've already figured it out, but a shell script containing the line `echo sun3' will do fine if it is somewhere on your search path. > An installation problem: People who care about Trojan horses > don't put "." at the beginning of their path, so shell scripts > invoked as "make" never get executed. Try "./make" instead. I don't see a clean way to fix this. Are any files affected besides WEBROOT/Makefile? The problem is that some of the calls to $(MAKE) are calls to shell scripts in subdirectories, while others are calls to /bin/make in the current directory.

Generating Modula-3 from a Modula-3 literate program should be no trouble at all. One the other hand, if you want to translate something else into Modula-3, you are probably better off using WEB-to-C as a basis. Let me know how it goes; I would love to have a Modula-3 spider file to add to the distribution.

Generally, the way to detect such a bug is to put an @2 in a very small test program, and then look at the resulting diagnostic output. The numbers are numbers of productions (from productions.list). Anyway I changed the following production so that it wouldn't swallow the angle brackets:: preproc !(less|lesssimp|backslash|newline) --> preproc > Second, if the first line of code is a preprocessor directive, it is > indented, so that it lines up with main(). Subsequent directives are > against the left margin. A bug in Knuth's unfathomable macros.

You will have trouble using the makefiles on other machines---I unknowingly used some features specific to Sun make (the @#$(&% man page didn't say `warning, not portable'), so things like `make boot' and `make distribution' may not work right. But `make weave' and `make tangle' work fine on a VAX running BSD4.3. > I'm > willing to help out with this any way I can as long as I don't get too > sidetracked from my regular work. Thanks for your help. I'm looking for a guinea pig to try to write a Spider file for ANSI C. Be aware that C is by far the most complicated language to prettyprint (of the ones in the distribution).

The problem is that some of the calls to $(MAKE) are calls to shell scripts in subdirectories, while others are calls to /bin/make in the current directory. What have you done to improve things? It seemed to compile after I changed Makefile in the top-level directory to say "./make", but I just now tried a "make -n clean" and found a few missing things. I'd suggest that in the case where you want "make" to mean "/bin/make" that you just drop in a shell script along the lines of /bin/make $* There's a fair chance that I'll be able to translate Pascal into Modula-3 with a little assistance. Another worthy project would be to get a dialect of Pascal output more acceptable to the brain-dead Pascal compilers used on Olivetti machines.

Actually a \ttverbatim kind of solution won't work, because \ttverbatim needs to be able to change the catcodes, and they can't be changed at that late date because the whole affair is an argument to another macro, and the characeters have already been gobbled up (or whatever the appropriate parts of TeX's anatomy that sets catcodes).

We have Don Knuth to thank for this. The lexer sees the code just once, and then converts everything to either eight or sixteen bit tokens. Output is very fast. I would like to speed up WEAVE some day, by making it run from a table (decision tree). Doing that and abandoning the internal conversion to ASCII would probably gain a factor of three. > Query?

Make is looking for a file common.o in a directory `arch` and not finding it, so it makes the target. You can cure the problem by replacing `arch` with $(ARCH) in the Makefile and using ARCH=`arch` in the make script that calls /bin/make.

It made me try it once again. > I have only two guesses: > -- you are somehow combining Spider with Silvio Levy's CWEB in a way > that doesn't work > -- you've got a buggy C compiler Quite right. I was combining Spider with Silvio Levy's CWEB. See note below. > Please let me know more if you can, or at least tell me how big your > tangle.c is, so I can tell if it makes sense. This time I tried to follow the instructions real hard and it worked! But I had some small problems. When doing 'make boot' the link of ceetangle and ceeweave tries to get the common object files from the cputype directory but they are not there. They are compiled in the master directory! I just removed the use of the cputype-directory and then it worked! I also managed to destroy the tangle.c file in the master directory when I typed 'make -p'. Well I shouldn't have done it but away it went. Then I realised that this was what happened the last time I tried to make spiderweb and that time I copied ctangle.c from CWEB just to try it. Stupid me! This time I went back to my copy of the distribution and got the real ctangle.c! The previous time I didn't realised that it ever was in the master directory. I though it simply was missing. The programs are using the 'index' function that's not available on SYSV. (I'm running HP-UX.) This should be substituted with 'strchr' since I think that this is now normally available on both SYSV and BSD systems. (I haven't checked that though! Maybe a macro is safer.) I found no other system problem. A small error when trying to print out the weave. I haven't tried to find out why it fails.

Thought you might be interested in a few minor changes I had to make. 1. In common.c I added the definition #define index strchr since the routine is named differently on SysV machines. I probably should have added a -DUSG compilation flag, but since this was the only dependency ... 2. In spider.awk, three sprintf lines were missing the surrounding parentheses: 1221c1221 < temp=sprintf"strncmp(\"%s\",loc-1,%d)==0",$2,length($2) --- > temp=sprintf("strncmp(\"%s\",loc-1,%d)==0",$2,length($2)) 1231c1231 < temp=sprintf"'%s'",$2 --- > temp=sprintf("'%s'",$2) 3040c3040 < temp=sprintf"(pp+%d)->cat",$i-1 --- > temp=sprintf("(pp+%d)->cat",$i-1) This was confusing, since BSD4.3 awk doesn't mind. 3. My awk then wouldn't digest c.spider or awk.spider, complaining of an awk : unexpected break, continue or next at record ### where ### was one more than the number of lines in c.spider or awk.spider. Rather than fight it, I installed gawk2.10 and everything went fine. (Note that gawk also burps on the missing parentheses mentioned in 2 above.)

Note that there wasn't anything in WEBROOT/README or EBROOT/master/WebMake which indicated that cputype has to return either sun3 or vax (or that a null directory has to be created).

You're not going to be able to do anything about this without fundamentally changing Weave's idea of what an identifier is. If you want you could make the preprocessor directives reserved words, suppressing their appearance in the index, but that will have unpleasant repercussions, I'm sure. If you really want to fix this you'll have to do some hacking. > This problem has to do with spacing in ANSI C function parameter > specifications. Consider the following short example.

What do you think? How might I "fix" @f? I think that if you're going to lie to your reader by using @f, your reader should at least have a chance to catch you in the act.

Typedefs not formated correctly by ceeweave. Only if you believe ``correctly'' == ``what Silvio does.'' The problem is that the logical structure of typedefs follows the structure of the C program, whereas the formatting is done on the structure of the WEB source. There are nasty problems of scoping, and even doing a botched job requires a two-pass algorithm. > I tried using @f to redefine them. > See second example.

Sorry to be so unhelpful, but I have been putting my time into new, better-designed tools, instead of continually patching web.
