This is a place to post snippets that are clever and/or useful.

This generates a banner comment that spans the distance between the current column and the edge column (which I have set at 80).

banner = [[/%<string.rep("*", buffer.edge_column - buffer.column[buffer.current_pos] - 1)>
 * %0
 %<string.rep("*", buffer.edge_column - buffer.column[buffer.current_pos] - 2)>/]],

Generates an inclusion Guard for C/C++ header files. Defaults to the file's name without its extension and capitalized.

incguard = [[#ifndef %1(%<(buffer.filename or ''):match('[^/]*$'):upper():match('^[^%.]+')>)_H
#define %1_H

%0

#endif
]]
