# 20150331 bkw: build 2
# Increase TUBE* constants in config.h to allow for larger terminals.

# vi has hardcoded terminal size limits of 160 columns and 100 lines.
# These days it's not unusual to have a 1920x1080 framenbuffer with 8x16
# console font, for 240x67 characters. Increase limits here. Doing so uses
# TUBESIZE bytes of memory at startup, and another TUBESIZE bytes every
# time you switch from ex mode to visual mode, so let's not get too crazy
# with the cheez whiz. The real problem is TUBECOLS (the width): if the
# terminal exceeds this, you get 'Terminal too wide' and are stuck in ex
# mode. Exceeding TUBELINES just means vi ignores the extra lines at the
# bottom of the terminal.

# Default to 320x200, which would be enough for a 8x16 console font on a
# WQXGA 2560x1600 display, or a 2/3-width full-height X terminal on 4K
# UHDTV (3840x2160). If I don't make this configurable, someone will
# need it to be. So:
TUBECOLS=${TUBECOLS:-320}
TUBELINES=${TUBELINES:-200}

# We now return you to your regularly scheduled programming:
