Field Details

FMPP_CONSOLE_COLS

public static final String FMPP_CONSOLE_COLS

The number of console (terminal) columns can be passed in with this environment variable, supposedly by the OS-specific starter executable (shell script). Note that if the Settings.NAME_COLUMNS is set, that will override this (but by default it isn't set). The value of the environment variable should be just an integer (with possible white space around it), however, if it's not a number, CommandLine will attempt to parse it as the output of the Windows mode con /status command (also then [BR] can be used instead of real line-breaks, to ease bat programming). On UN*X-es usually this should be the output of tput cols.
