$buffer-names(5)

NAME

$buffer-names - Filtered buffer name list

SYNOPSIS

$buffer-names BufferName

DESCRIPTION

$buffer-names must first be set to the required filter string, if the variable is evaluated before it is initialized the value will be set to "ABORT" and the command will fail.

The filter string can contain wild-card characters compatible with most file systems, namely:-

?


Match any character.

[abc]


Match character only if it is a, b or c.

[a-d]


Match character only if it is a, b, c or d.

[^abc]


Match character only if it is not a, b or c.

*


Match any number of characters.

Note that these are not the same characters used by exact(2m) mode.

Once initialized, evaluating $buffer-names returns the name of the next buffer which matches the filter until no more buffers are found, in which case an empty string is returned.

EXAMPLE

The following example prints out the name of all buffers to the massage line one at a time. Note that &set(4) is used on the !while(4) statement to avoid evaluating $buffer-names twice per loop.

set-variable $buffer-names "*" 
!while &not &seq &set #l0 $buffer-names "" 
    100 ml-write &cat "buffer: " #l0 
!done 

The following example is the same except it lists only the buffers which are not directory listings

set-variable $buffer-names "*[^/]" 
!while &not &seq &set #l0 $buffer-names "" 
    100 ml-write &cat "buffer: " #l0 
!done 

NOTES

The list of buffers is evaluated when the variable is initialized, buffers created after the initialization will not be included in the list.

Deleting buffers which are in the list, before they are evaluated, will have undefined effects.
