问题 Is there any kind of common lisp docs like javadoc, man or even intellisense-like popups? I've just started learning common lisp and do not have enough hand memory. I am using emacs and slime — it has tab completion, but it seem not very informative.

If you search Google for something like "hyperspec function-name" there's a good chance you will land on one of them.

问题 This question is based on the thread. I have the shell function function man() { man "$1" > /tmp/manual; less /tmp/manual } The problem is there exists the command man. How can you replace the command with my command? 回答1: Replace man "$1" with the pathname: /usr/bin/man. Or change it to use 'which man' within backquotes. Then run your script in the current shell. On bash/ksh you need to save your script in some file, say man.sh and then run it as '. ./man.sh'. cat > man.sh function man() {

问题 I'm working on a lab that is supposed to help us better navigate the command line on a Linux system, but I'm getting stuck on man pages. We are supposed to use the man command to find a list of the man page sections, adn I can't seem to figure out how to do this. I've tried entering man man but that doesn't give me any information on the individual sections. I've also tried looking on Google to find what command I should use, but no luck there either.

问题 I ran into this question while typing man 2 open . It says that there are two kinds of open, one with two args, and one with three! last time i checked we could not overload functions in C. How did they do this? did they write in C++? int open(const char * pathname, int flags); int open(const char * pathname, int flags, mode_t mode); 回答1: No, they just used variadic function. int open(const char * pathname, int flags, ...); This makes the last argument mode optional. The prototypes only show
