### Configuration files

This lens applies to /etc/sysconfig/rhn/up2date. See filter.

### Examples

The Test_Up2date file contains various examples and tests.

### USEFUL PRIMITIVES

### key_re

> let key_re = /[^=# \t\n]+/

### value_re

> let value_re = /[^ \t\n;][^\n;]*[^ \t\n;]|[^ \t\n;]/

### sep_semi

> let sep_semi = Sep.semicolon

### ENTRIES

### single_entry

> let single_entry = [ label "value" . store value_re ]

key=foo

### multi_empty

> let multi_empty = sep_semi

key=;

### multi_value

> let multi_value = [ seq "multi" . store value_re ]

One value in a list setting

### multi_single

> let multi_single = multi_value . sep_semi

key=foo; (parsed as a list)

### multi_values

> let multi_values = multi_value . ( sep_semi . multi_value )+ . del /;?/ ";"

key=foo;bar key=foo;bar;

### multi_entry

> let multi_entry = [ label "values" . counter "multi" . ( multi_single | multi_values | multi_empty ) ]

List settings go under a ‘values’ node

### entry

> let entry = [ seq "entry" . store key_re . Sep.equal . ( multi_entry | single_entry )? . Util.eol ]

### LENS

### lns

> let lns = (Util.empty | Util.comment | entry)*

### filter

Provides unit tests and examples for the Up2date lens.
