Visualizzare i segni di tabulazione ed a capo con vim
You can use
:set list
(which defaults to "nolist"), which shows tabs as ^I and puts a "$" at the end of lines.
You can also define highlighting regions with "syn match" to define a single tab.
You can then link this to whatever highlighting you like perhaps using the following:
:syn match TAB_CHAR "\t" :hi link TAB_CHAR Error
