Regexes used in country outlines project
edit- Multi-line find and replace involving addition of text after an ordinal numeral (first, second, etc.), done using these strings of RegEx in AWB:
find="(th|nd|rd|st)(\]\])(\r\n?|\n)(\* \[\[Area of \]\]:)" replace="$1 most populous country$2$3$4"
find="(th|nd|rd|st)(\]\])(\r\n?|\n)(\* \[\[:commons:Atlas of )" replace="$1 largest country$2$3$4"
- (See User talk:Robert Skyhawk/Country Outline task list#Regex tasks for full details)
Grabbing data off another page and inserting the text into country outlines
editOk here is the way I do it: there isn't really code to share it was a one off.
1. use wget to recover the data 2. Use a perl script to create a set of AWB rules (regex encapsualted in XML) 3. Insert a suitable tag into each page using the %%title%% feature of AWB or {{subst:PAGENAME}} 4. Run AWB against the pages
Note 3 and 4 can be done in one hit, although I took two passes.

Regex question
edit(I have the regex gadget installed above the edit window).
Below is a watchlist for use with Related changes. How would I use regex to add the corresponding talk page to the end of every entry on the list?

I look forward to your reply.

Not sure how that works exactly but you'd want to do something that has the effect of this, where txt is the content of the edit-window:
txt = txt.replace(/\n\*\s*\[\[([^\]]+)\]\]/g, "\n*[[$1]] ([[Talk:$1|talk]])");
// or better yet if you want a bunch of other links use a template
txt = txt.replace(/\n\*\s*\[\[([^\]]+)\]\]/g, "\n*{{article|$1}}");
That would work for the article pages anyway. The other stuff would be more complicated. — CharlotteWebb 21:38, 16 June 2009 (UTC)
- Hold on a sec... I think that I can do this. I've done it with watchlists before, thanks to the handy {{swl}} template. –Drilnoth (T • C • L) 22:05, 16 June 2009 (UTC)
- It looks like it's now done, but if you wanted to do it with the Regex-tab script, you could have replaced
\* \[\[([^\]\[]*)\]\]
- with
* {{swl|$1}}
- which is effectively what Drilnoth did on the page in question. The '\[' means a literal bracket character, the '\*' is a literal asterisk, the '[^\]\[]' means any character other than brackets, and the parentheses saves the match so it can be referenced later as '$1'. I hope this makes sense. Plastikspork (talk) 00:04, 17 June 2009 (UTC)
