Text Editing
Tab width
Code MUST be indented with tabs. Anyone who tells you otherwise is simply foolish or misinformed. For those who don't like massive indentations, that's why tabs are magical. Below you can set your tab width for a few of the worthy text editors (4 columns in these examples). Any text editor that doesn't let you specify tab widths isn't worthy of the title. No further discussion is necessary.
