I'm probably not using this board right but hopefully someone can help me out. I'm relatively new to perl... but I've done a little bit of batch scripting so I am used to how the language works and can learn easily. My problem is that I need to copy a file from one drive and paste it into a folder on a different drive. This process takes place daily and is followed by other tasks, but I need to know how to copy a file whose name is always different because there is a date stamp in the middle of the file name. If anyone can help me out i'd be greatly appreciateive. PLEASE HELP ME!
The Xml Deserializer functions parse an XML file and give you a basic object of the nodes and attributes. Using the discography xml fragment below as an example, you can do:
myData.album._title myData.album.song[0]._href; // this is if the <album> node had node text // <album title="blah">Album Content</album> myData.album.__content__
Pick it up piping hot at http://rubyurl.com/q05.
#include "xml_deserializer.as"
/* Sample XML file
<discography>
<album title="Late For The Sky" year="1974">
<song title="Late For The Sky" href="late_for_the_sky.mp3"/>
<song title="Fountain Of Sorrow" href="fountain_of_sorrow.mp3"/>
</album>
</discography>
*/
// xml callback function
function parseDiscography(success) {
if(!success) return;
XmlDeserializer.parse_nodes(myData, XmlDeserializer.xml_object.childNodes[0]);
play();
var albums = XmlDeserializer.get_items(myData.album);
for(var a=0; a < albums.length; a++) {
var album = albums[a];
var songs = XmlDeserializer.get_items(album.song);
for(var s=0; s < songs.length; s++) {
var song = songs[s];
if(song._href != undefined) {
var song_obj = {
title: album._title + ' :: ' + song._title,
href: myDiscoPath + song._href
};
// global array used by flash
mySongs.push(song_obj);
}
}
}
}
// object used by XmlDeserializer class
var myData = {};
// strip off disco.xml
var myDiscoPath = myDisco.substr(0, myDisco.length-9);
//XmlDeserializer.debug = true;
// myDisco is url to discography xml file
XmlDeserializer.parse_xml(myDisco, parseDiscography);
Spider a directory using:
find . -type d ! \( -name "*CVS" \) -exec python cvsAdd.py {} \;
find . -name "*.py" -exec python cvsAdd.py {} \;
in cvsAdd.py, put the following:
import sys, pexpect, getpass
PASS='myPass'
def cvsAdd(fname):
global PASS
if not PASS:
PASS = getpass.getpass()
child = pexpect.spawn('cvs add "%s"' % fname)
child.expect("me@my-cvs-host password:")
child.sendline(PASS)
for line in child:
print line
cvsAdd(sys.argv[1])
It seems like a simple task, but here's how you can simulate the calling of a controller's action:
ruby script/console irb> require 'action_controller/test_process' irb> require 'application' irb> require 'site_controller' irb> request = ActionController::TestRequest.new irb> response = ActionController::TestResponse.new irb> request.env['REQUEST_METHOD'] = 'GET' irb> request.action = "late_employee" irb> InfoController.process(request,response)
Basically, it's like getting inside of a TestUnit method, but you have to do the dirty work yourself.

function checkPhone(str)
{
var phone2 = /^(\+\d)*\s*(\(\d{3}\)\s*)*\d{3}(-{0,1}|\s{0,1})\d{2}(-{0,1}|\s{0,1})\d{2}$/;
if (str.match(phone2)) {
return true;
} else {
return false;
}
}
Phone format phone: 339-4248 339-42-48 339 42 48 339 4248 3394248 (095) #phone# (095)#phone# +7 (095) #phone# +7 (095)#phone# +7(095) #phone# +7(095)#phone#

Show the currently viewed category as a heading outside of the {weblog.entries} tag.
Engineering format lists the exponent in powers of three
def number_to_engineering(value, precision=3)
expof10 = ((Math.log10(value)/3.0).floor)*3
value *= 10**(-expof10)
case
when value>=1000.0 :
value /= 1000.0
expof10 +=3
when value>=100.0 : precision -= 2
when value>=10.0 : precision -= 1
end
"%.*fe%d" % [precision-1, value, expof10]
end
number_to_engineering(15000) => "15e3"
For those of us who can't remember the formatting codes
def number_to_scientific(num,precision=3)
"%.#{precision}e" % num
end
number_to_scientific(10000) => 1.000e004
in some cases it might be better to use the 'g' code instead of the 'e' code.
def number_to_ordinal(num)
num = num.to_i
if (10...20)===num
"#{num}th"
else
g = %w{ th st nd rd th th th th th th }
a = num.to_s
c=a[-1..-1].to_i
a + g[c]
end
end
number_to_ordinal(12) => "12th"
number_to_ordinal(7) => "7th"
Note that floats will be converted to ints (without rounding) before processing.
Actually, you can customize the separators to your needs.
def text_list(listtext,sep1=", ", sep2=", and ") n=listtext.size if n>1 : (listtext.first(n-1)).join(sep1) + sep2 +listtext.last else listtext.first end end text_list(["cat", "dog", "bird"]) => "cat, dog, and bird"

Does an svn export from rails. Provide a revision if you don't want to check out the latest. It then applies patches in config/diffs in alphabetical order.
