# SYNOPSIS
#   __config_settings_get_val <varname> <scope>
#
# DESCRIPTION
#   Returns the current value of a named variable in the specified scope by
#   parsing `set --show` output. Outputs "on", "off", or "DEFAULT" (when
#   the variable is not set in that scope). Scope "session" maps to "global"
#   in fish's internal terminology.
#
# ARGUMENTS
#   varname  Variable name without $ prefix
#   scope    "universal" or "session"
#
# RETURNS
#   0  Always; prints "on", "off", or "DEFAULT" to stdout
#
# EXAMPLE
#   set result (__config_settings_get_val __fish_config_op_aliases universal)
#   # result == "on" | "off" | "DEFAULT"
