# How wide to allow formatted cmake files

line_width: 255

# How many spaces to tab for indent
tab_size: 2

# If true, lines are indented using tab characters (utf-8 0x09) instead of
# <tab_size> space characters (utf-8 0x20). In cases where the layout would
# require a fractional tab character, the behavior of the fractional
# indentation is governed by <fractional_tab_policy>
use_tabchars: false

# If <use_tabchars> is True, then the value of this variable indicates how
# fractional indentions are handled during whitespace replacement. If set to
# 'use-space', fractional indentation is left as spaces (utf-8 0x20). If set
# to `round-up` fractional indentation is replaced with a single tab character
# (utf-8 0x09) effectively shifting the column to the next tabstop
fractional_tab_policy: "use-space"
