# Convert SNC Regex expressions to enhanced regex expressions

# Convert SNC Regex expressions to enhanced regex expressions {#ariaid-title1}

When you upgrade to Eureka Patch 5 or later releases, you should convert scripts that
use the SNC.Regex API to use regular JavaScript expressions.

## Procedure

1. From the original expression, such as: `SNC.Regex("/expr/is");`, create a new regular expression object using the pattern with the slashes stripped.  

       new RegExp('expr');

2. Move the SNC.Regex flags to the start of the expression using Java's inline flag special construct.  

       new RegExp('(?is)expr');

3. Add the <var class="keyword varname">j</var> flag to the `RegExp` to tell the engine to treat the expression as a Java expression.  
   Note:  
   If you know that the script being converted does not use Java syntax, it is not necessary to use the <var class="keyword varname">j</var> flag.  

       new RegExp('(?is)expr', 'j');

4. Add the <var class="keyword varname">g</var> flag to handle multiple matches or a global replace.  

       new RegExp('(?is)expr', 'jg');

## Example

Using SNC.Regex:

    var r = new SNC.Regex('/world/');
    var str = 'helloworld';
    var replaced = r.replaceAll(str, 'there');
    // replaced == 'hellothere'

Using a JavaScript regular expression:

    var r = new RegExp('world', 'jg');
    var str = 'helloworld';
    var replaced = str.replace(r, 'there');
    // replaced == 'hellothere'
