Smart Tabs

Indent with tabs; align with spaces

See EmacsWiki › SmartTabs for details about the idea this package enables.

Summary:

// Tab size: 4                // Tab size: 2
if(foo) {                     if(foo) {
--->char quux[4] = {0, 1,     ->char quux[4] = {0, 1,     // "0" and "2"
--->................2, 3};    ->................2, 3};    // remain aligned
}                             }

Tabs are only used at the beginning of lines. Everything else, like ASCII art and tables, should be formatted with spaces.

Tabs are only used for expressing the indentation level. One tab per “block” – any remaining whitespace is spaces only.
