If I do (push "." load-path) then maybe I did that in ~/ directory, where I expect to find my-library.el and when I switch to ~/tmp directory and try to load my-library.el it would not work as now "." is inside of ~/tmp and not ~/ > I have . first in the shell PATH as well to execute scripts > there quickly, but also to give precedence if some binary > somewhere deep in the system has the same name. Maybe good, I just don't put executables everywhere, so I never had "." in my life in the shell PATH. Sure is working if you need it. It is not similar to "." in load-path in Emacs. > > , imagine that require would not work depending of the > > current directory. > > What do you mean, when that file is byte-compiled, isn't the > current directory that of that file, i.e. just where it should > look first to require stuff?

Is it well enough explained above? If you just add "." that means current directory, and in Emacs you can easily switch current directory. For example if you look for file in some directory, the current directory is changed. If library you look for was in "." when you were in ~/ directory, you will not be able to load that library if you switch current directory to some other location. I have tried and it does not work. "." if not expanded to actual directory such as ~/tmp will not help in loading files from ~/tmp as "." alone does not know it is ~/tmp, as it points to whatever current directory is currently. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns Sign an open letter in support of Richard M.
