Regex in Groovy: Match characters and some special ones

I’m writing a script that validates a file with key/value-pairs. One type of a valid value is a JNDI-name. Before the actual name it is also a whitespace. So my if-statement with the regex validating ended up like this

currentLine ==~ /^.*=\s+[A-Za-z0-9\/-]+/

To explain it:

  • ==~ means validate true/false, see http://groovy.codehaus.org/Tutorial+4+-+Regular+expressions+basics
  • Then the regex starts and ends with a forward slash
  • ^.*= means match lines with text containing any type of character ending with an equal sign (the keys)
  • \s+ means match one or more whitespaces. Should really just need to verify one and only one, but what the heck…
  • [A-Za-z0-9\/-]+ is a character class saying match all uppercase letters, all lowercase, all numbers and also forward slashes and hyphens. Some of the names have hyphens so I needed that one to. The + sign at the end says “one or more occurences”, see the heading “Regular Expression Operators” found on the above mentioned link

Handyman in action yet again

Yesterday helping Vegard out carrying roof tiles just to realize today that riding the bike 5 days a week does not build muscles. Luckily Vegard is a hard core handyman, he has even built his own truck using an old tractor and parts from an actual truck, how cool is that? So we only had to spread them out on the roof, good thing we did not have to carry them up the ladder as well.

Crude – The real prize of oil

Have you seen the movie about Texaco (Chevron) and how they have polluted land in Ecuador? Would recommend you not to, since you will only feel a stronge urge to kick some ass, especially the Chevron employees. I would hope people like the scientist Sara is a liar, because there are no lies told, she and her coworkers must be the worst kind of scientist.

I guess there are plenty of things that the president of Ecuador, Rafael Correa, could have done better, but the decisions he has made in this case is proving that he is a wise man.

Kamikaze bird

Found this bird out on the balconyhere the other day. At first I thought it was stuck in the grill, but he wasn’t. So I assume he has tried to fly through the window in the balcony door. Quite funny when Elin noticed it 🙂
