# Padre::Wx::Dialog::PerlFilter(3pm)

dialog to make it easy to create a regular expression

## NAME

Padre::Wx::Dialog::PerlFilter - dialog to make it easy to create a regular expression

## DESCRIPTION

The `"Regex Editor"` provides an interface to easily create regular expressions used in Perl.

The user can insert a regular expression (the surrounding `"/"` characters are not needed) and a text. The `"Regex Editor"` will automatically display the matching text in the bottom right window.

At the top of the window the user can select any of the four regular expression modifiers:

- Ignore case (i)

  - Single-line (s)

  - Multi-line (m)

  - Extended (x)

  Global match

Allow the change/replacement of the // around the regular expression

Highlight the match in the source text instead of in a separate window

Display the captured groups in a tree hierarchy similar to Rx ?

```
  Group                  Span (character) Value
  Match 0 (Group 0)      4-7              the actual match
```

Display the various Perl variable containing the relevant values e.g. the `"@-"` and `"@+"` arrays, the `"%+"` hash `$1`, `$2`...

point out what to use instead of `$@` and `"$'"` and ``"$`"``

English explanation of the regular expression
