I use strace(1) look for stat(2) syscalls that fail with ENOENT. An advantage of this approach is that I do not have to imitate the C preprocessor, so parser differentials can never happen. The following default.o.do file from my blog post

Please elaborate: What do you find amazing about scons? Also, how does scons handle non-existence dependencies? What would be a scons dependency graph for this C code? #include<stdio.h> main() { printf("hello, world\n&qu

There exists DJB's redo approach [0], which i implemented [1], where dependencies and non-existence dependencies are only recorded after the build. A typical dofile is a shell script, so you do not need to learn another language. Targe

An issue I have with make is that it can not handle non-existence dependencies. DJB noted this in 2003 [1]. To quote myself on this [2]: > Especially when using C or C++, often target files depend on nonexistent files as well, meaning th

While you are right about POSIX problems (like using “local”) I actually targeted Dash and older versions of BusyBox – not Bash. I plan to work on POSIX compatibility for my redo implementation.

Why do you think the problem can not be fixed? Also, have you looked at the redo tool redo-ifcreate? http://news.dieweltistgarnichtso.net/bin/redo-sh.html

by erlehmann_ 9y ago
Almost all other systems have this flaw because they require dependencies before a build. If recording dependencies after the build, the entire problem becomes very simple. See here: http://news.dieweltistgarnichtso.net/post

Yes, all of those are reasons. None of those reasons apply if users wwant something understandable, maintainable and secure. Separation of concerns is a thing that can help designers, no?

Templates cause bugs. The solitary appropriate solution is an unparser – a component that walks an AST and serializes it. Making sure the result conforms to the grammar of the output language without any unparser would always involve a pars

I think when undefined behaviour is used for optimizations the programmer does not want it is more of a misunderstanding than one party (programmer or compiler) necessarily being “wrong”, as a compiler assumes that a program should make sen

To me, undefined behaviour analysis and typing analysis seem very similar: Both allow a compiler to infer things that can help improve performance … So why do you see the claims that both can help performance as “opposite”?
