Very weirdly, there seems to exist no way to know the cursor position in a terminal without clearing it and keeping track of the cursor, which a shell obviously cannot do since it can't control the output of the programs it launches (that is why my theory that zsh uses ncurses doesn't seem to hold, although it is very possible that it uses some ncurses functions).
Really? I thought this is what the ^[[6n escape sequence was for? Besides:
I checked the zsh source code but I'm not used to doing such things, and besides, it's quite like looking for a needle in a haystack (even though I'm fairly confident the code is situated in the zle part)...
That makes it sound like you just started programming, and are thinking that writing your own shell can't be that hard, since there are so many around. Well, the source code for KSH93 (which has far less features that zsh) comes in at roughly 2.5 MiB of code, and that's not counting any supporting libraries from the same archive.
Could anybody help me.

How would you do vim copy line and paste at the beginning, middle, and end of another line. I know yy copies the whole line and p pastes the whole line, but on its own separate line. Sometimes I would like to copy a line to the beginning, middle, or end of another line. I would think this would be... (3 Replies)

libdl(3LIB) Interface Libraries libdl(3LIB)NAME
libdl - dynamic linking library
SYNOPSIS
cc [ flag... ] file... -ldl [ library... ]
DESCRIPTION
Historically, functions in libdl provided for dynamic linking support. This functionality now resides in libc(3LIB).
This library is maintained to provide backward compatibility for both runtime and compilation environments. The shared object is imple-
mented as a filter on the runtime linker. See ld.so.1(1). New application development need not specify -ldl.
INTERFACES
The shared object libdl.so.1 provides the following public interfaces. See Intro(3) for additional information on shared object interfaces.
dladdr dladdr1
dlclose dldump
dlerror dlinfo
dlmopen dlopen
dlsym
