file plugin

This plugin allows reading of a line from a file.

This plugin returns up to 80 characters of a line from a file. Characters after that in the line are simply ignored.

The plugin could be a logical place to add more file operations, such as size, permissions display, etc.

Widget dmesgline99 {
    class 'Text'
    expression file::readline('/var/log/dmesg', 99)
    width 20
    align 'M'
    update 10000
}
