RegexMagic

Click the RegexMagic button on the Search toolbar of the AceText Editor or press Ctrl+Shift+R in AceText to launch RegexMagic. Click the Send button on the Regex panel in RegexMagic to send the generated regular expression to AceText.

RegexMagic allows you to create regular expressions by using high-level RegexMagic patterns to describe the text that you want to match. RegexMagic then generates the regular expression for you. With RegexMagic, you don’t need to deal with the terse and cryptic regex syntax at all.

RegexMagic is a separate product available from Just Great Software, the developer of AceText. If you don't have it installed, then the RegexMagic button in AceText shows a message introducing RegexMagic.
