Double Line Numbers. The prettyPrint method does not check if the element has already been prettified #261

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create a an element with code to prettify and specify to add line numbers
2. Call pretty print twice. For us, this happens because some of our page 
content is fetched via ajax that triggered by user interaction. The returned 
markup can contain code samples so we have to call prettyPrint on page load for 
existing content and again after every ajax call for code samples in the 
response.

What is the expected output? 
We would expect that addition line numbers would not appear.

What do you see instead?
A nested ordered list with multiple line number columns.

This:

1. example() { // some code goes here }

Becomes this after the second call to prettyPrint():

1. 1. example() { // some code goes here }

I am using "prettify-small-1-Jun-2011.tar.bz2" with bootstrap.css theme.
This issue arises when you run prettyPrint(); more then once on a single page.

Find file attached, which shows output of running prettyPrint() 5 times.

Ok, got it. The problem is with:

http://google-code-prettify.googlecode.com/svn/branches/release-1-Jun-2011/src/p
rettify.js

which is not yet up-to-date.

./svn/trunk/src/prettify.js is fine; no duplicate line number issue.

Sorry for the delayed response. Just confirming that it is 
http://google-code-prettify.googlecode.com/svn/branches/release-1-Jun-2011/src/p
rettify.js version which will repoduce the issue.

The latest release should include a fix for this issue.
