$buffer-mask(5)

NAME

$buffer-mask - Current buffer word class mask.

SYNOPSIS

$buffer-mask string; Default is luh

DESCRIPTION

$buffer-mask sets the current buffer word class mask. MicroEmacs has an internal word lookup table which defines whether a given letter is considered to be part of a word. This functionality is used in many areas such as forward-word(2), forward-kill-word(2) hilighting etc. The mask is composed with any combination of the following flags, the order in which the flags are specified is not important:

l


All lower case letters.

u


All upper case letters.

h


All hexadecimal characters (used to include numerical digits).

s


Spell extended characters, typically set to accent ('), hyphen (-) and period (.).

1


User set 1, usually set to just underscore (_) for many system and programming files such as 'C'.

2


User set 2, usually set to '-', '$', '&', '#', '!', '%', ':' and '@' for MicroEmacs files.

3


User set 3, not usually defined.

4


User set 4, not usually defined.

The character sets may be modified using the set-char-mask(2) command.
