Ratel - Edit Rule
This dialog box allows you to edit the data of a rule.
Expression before the position — Enter the regular expression for the text just before the break point of this rule. The expression must be a valid regular expression.
Expression after the position — Enter the regular expression for the text just after the break point of this rule. The expression must be a valid regular expression.
Note that SRX 2.0 regular expressions are ICU regular expressions. See the "SRX and Java" page for more details.
Insert a segment break at this position — Select this option to define a segment break.
Do not break at this position — Select this option to prevent a segment break.
Example:
before: [Ee][Tt][Cc]\. after: \s is a break: no before: \. after: \s is a break: yes
Note that most of the time you list non-break rules (exceptions) before break rules, so they are evaluated before the break rules.
