Question

Someplace I saw a snippet of code which told vi to use soft tabs and set the size of a tab. If you put this snippet at the bottom of a source file, then vi would magically use those settings for that file.

What is the syntax and rules for including that snippet in a source file? Can emacs be made to use these settings as well?

Answer 1

You can put this in a comment in your source file:

ex: set softtabstop=4 shiftwidth=4 tabstop=4 expandtab: 

The comment syntax depends on the type of the source file.

For C/C++/Java, this would be:

// ex: set softtabstop=4 shiftwidth=4 tabstop=4 expandtab: 

For JSP, this would be:

<%-- ex: set softtabstop=4 shiftwidth=4 tabstop=4 expandtab: --%>

This works if it is placed at the beginning of the source file, but I’m not sure that this’ll work if placed at the end of it too.

This will not work for emacs. There might be a different way of achieving the same for emacs.
