Summary

How to get a list of programming tasks *without* solutions

Discussion

I'm going on a long plane trip. I'd like to take a printout of all the tasks but without the solutions. I have in mind to solve some of the solutions on paper whilst airborne, taking the list of solutions and the programming language manual. Axtens (talk) 07:04, 27 March 2015 (UTC)

Sounds like a good idea for a task "Extract task description from an RC task" (i.e. down to the first {{header|...}} :-)

I'd approach this by downloading all the tasks (approximately: all the rosetta wiki links from http://rosettacode.org/wiki/Category:Programming_Tasks which do not have a ':' in the url's path), and then clip them off starting at the line which contains "mw-headline"). That should get you close enough?

In other words, something like this:

<lang bash>wget -k http://rosettacode.org/wiki/Category:Programming_Tasks

lynx -force_html -dump Category%3AProgramming_Tasks | awk '/http:..rosettacode.org.wiki/{print $2}' | grep -v ':.*:' | xargs wget --wait=1 -kp find rosettacode.org/wiki -type f | xargs perl -i -0777 -pe 's/\n[^\n]*mw-headline.*//s'</lang>

Change perl's -i option to -i.bak if you feel like you might want to save the originals.

You'll probably want a .html extension on those files, though, so also:

<lang bash>find rosettacode.org/wiki -type f | while read f; do mv $f $f.html; done</lang>

This will leave the table of contents in place, if but you could remove that if you like, using a similar approach. (Make a copy of your work before experimenting, so you do not overburden the site. When the site is overburdened, nobody can pull down content from it - including you.)

I hope this helps. --Rdm (talk) 14:58, 27 March 2015 (UTC)
