Hi
I am trying to execute a command from within a groovy script. For instance

md5sum /home/user/some file name with a space

but any filename with a space is giving an error. I've tried the following without success.

def md5cmd = "md5sum $fileName"
Process proc = md5cmd.execute()

and

def md5cmd = "md5sum \"$fileName\""


Does anyone have any suggestions on how I can pass build up an argument list that will prevent the No such file or directory.

Note:
OS is ubuntu linux

I would be greatful for any suggestions

Found the following on the authors website : http://www.manning-sandbox.com/thread.jspa?threadID=33351&tstart=0

.flattern() works too.

Hello again.
I'm slowly getting there with groovy and working through the example listings in GinA but this time I think I really have found an example that doesn't work with the latest version.

Listing : 7.23
class Invoice { List items Date date } class LineItem{ Product product int count int total(){ return product.dollar * count } } class Product { String name def dollar } def ulcDate = new Date(107,0,1) def ulc = new Product(dollar:1499, name:'ULC') def ve = new Product(dollar:499, name:'Visual Editor') def invoices = [ new Invoice( date:ulcDate ,items:[ new LineItem(count:5, product:ulc ) ,new LineItem(count:1, product:ve ) ] ) ,new Invoice(date:[107,1,2] ,items:[ new LineItem(count:4, product:ve ) ] ) ] assert [5*1499, 499, 4*499] == invoices.items*.total()

I'm guessing this doesn't work because GinA assumes 1.0 and I'm on 1.6.5.

I found this bug http://jira.codehaus.org/browse/GROOVY-2387 which recommends replacing the last line with
assert [5*1499, 499, 4*499] == invoices.items.sum()*.total()

An obvious question is where did sum() come from?

Can anyone explain how I should be using spread (*.) operator in the later version of groovy as it seems like a really powerful feature

My final question is, are there many of these gotchas in the groovy GDK which newbies should be aware of ?

Doh, school boy error. Can't believe I didn't check the pattern first.


Thanks again.

Hi Guys,
The following code is a modified example from Groovy in Action but I don't understand what it does.


def host = /\/\/([a-zA-Z0-9-]+(\.=a-za-Z0-9-])*?)(:|\/)/ def assertHost(candidate, regex, expected){ println("CANDIDATE $candidate") println("REGEX $regex") println("EXPECTED $expected") candidate.eachMatch(regex){ println( 'matched candidate with regex') assert it[1] == expected } } assertHost ('http://www.google.co.uk:8080/bla', host, 'a.b.c' ) assertHost ('http://a.b.c/bla', host, 'a.b.c') assertHost ('http://127.0.0.1:8080/bla', host, 'a.b.c') assertHost ('http://www.google.co.uk:8080/bla', host, 'a.b.c') assertHost ('http://www.google.co.uk:8080/bla', host, 'a.b.c' )

I never seem to be able to get the 'matched candidate with regex' (which is what I think the code is supposed/!supposed to do) regardless of how I change the 1st / 3rd argument. Has anyone got any suggestions on what needs to be changed in order to make it work and print out this line.

The code is from page 165 of the book and I'm using groovy 1.6.5

Thanks
Kris

Hi all
I would appreciate any suggesstions on the following scenario. I have the following.

Page 1:
Command Button

Page 2:
OutputText
OutputText2
PrePopulateFields()

When a user presses the command button on page 1 I wish to execute PrePopulateFields() and then direct the user to that page or redirect the user then call PrePopulateFields(); I'm not fussy so long as the fields displayed are updated.

Can anyone tell me whether this is possible and how to do it.

Thanks in advance
Kris.
