Using beanshell in a macro
Submitted by pbolger on Wednesday, 17 February, 2010 - 21:44
I'm trying to write a macro to renumber footnotes links in a document - it's pretty simple: I just need to capture the previous number in a backreference, add an offset to it, and rewrite the link with the result. I've got the regex search worked out, but I'm completely in the dark on the syntax for the replacement. This looks like a situation where using a beanshell snippet would be appropriate, but I'm no java programmer. What I need is: [value in backreference plus the offset number] Any help would be appreciated.

Beanshell Snippet

If You'd have this:
- line: "word 15 anything"
- search string: "(\w+ *)([0-9]+)"

there were two submatches found:
submatch 1 = "word "
submatch 2 = "15"

In the replace beanshell snippet the submatches are reffered to as "_x". So, with

this beanshell snippet: "_1 + (Long.valueOf(_2)+5000)"
You get this result: "word 5015 anything"

Thanks for that Robert.

If it's not too much trouble: do you mind telling me the syntax for literal text - I need to wrap the submatch results in the new tag - which is nothing like the old one.

Something like (open tag)link title="title" href="eznode://72#+(Long.valueOf(_1)+23)+(close tag)+(Long.valueOf(_1)+23)+(open tag) /link(close tag)

I'm not really sure about Your question. In Java "this is Literal text". Smiling

Except that my 'literal text' includes characters such as quote marks which close the literal text string. Do I need to escape special characters, or can I enclose the whole lot in a CDATA type container? Sorry to be a pain, but all the resources I've found on this so far assume a lot of basic knowledge of Java that I just don't have.

I'm afraid You won't be able to script in BeanShell without basic Java knowlege because it's nearly the same.

For Strings usage look there: http://java.sun.com/docs/books/tutorial/java/data/characters.html.
