SVN - Simple Guide (linux and windows command line)
Note: For the examples I have used an imaginary SVN repo (reository) called: ----http://test.talkphp.com-----. On this repo i have imported 2 TalkPHP scripts:
in order to give some meaning to the examples.
Also '$' denotes the linux command line, i dont know any GUI's so someone else will have to write about them, the commands here are identical to SVN on the windows command line (you will need to download the Binarys from the SVN site)
The general structure is (basic, im not going into trunk tags and branches):
N.B.For more information about the extra options type
svn co --help
You can either use checkout or the shorthand co, you may also need to specify a username and pass, you can specify these by typing --username and --password otherwise it will use the username you are currently using on your computer, in my case 'sam' which is incorrect for the repo's username 'sketchmedia'
$svn co http://repo/dir --username sketchmedia --password xxxxxxx
I want to checkout the TalkPHP_Login folder from the repo and I want to save it in a folder called 'testdir' (this is optional, if not specified it will create a dir based on the folder name being checkout) on my local machine, here is the SVN command to do so (with the results below, the lines beginning with 'A' are results, basically it means Added to the local DIR):
$svn co http://svn.assembla.com/svn/talkphp/TalkPHP_Login testdir
Checked out revision 25.
If no dir name specified:
$svn co http://test.talkphp.com/TalkPHP_Login
We can also checkout 2 different directories (and repos i think) from SVN
$ svn co http://test.talkphp.com/TalkPHP_Login http://test.talkphp.com/TalkPHP_Gravatar
Checked out revision <revision number>.
Checked out revision <revision number>.
As you can see it checked out both folders from the repo.
Checkout acts recursively, in other words will recursively download everything from that root dir (the one you specify) as you can see from the above examples. To stop this behavior you can use the -N arg:
svn co http://svn.assembla.com/svn/talkphp/TalkPHP_Login -N
Checked out revision 25.
Here you can see it only checked out the contains of the root and did not recursively download the rest.
You can also specify a revision to download, a revision is a snapshot of the code from the past (or future), for this you use the '-r' flag then the revision number, in our previous example it stated 'checkout revision 25' which is the current revision or 'HEAD' in SVN speak. I will use the -r flag to retrieve revision 24:
$svn co http://svn.assembla.com/svn/talkphp/TalkPHP_Login -r 24 -N
Checked out revision 24.
That's about it for a rough guide checkout, any questions just ask.
I'll finish the other parts and post them later.

SVN or any VCS like CVS etc help control files and the changes to them, it basically allows you to track them over time. Each file is given a 'revision' number and every time a change is made to that file the revision number increments thus allowing you to do all sorts of things.
I make a change to the code held within the repository and lets say, I made a right hash of it; well with a vcs its easy to just revert back to a previous revision number (in svn i believe its called a reverse merge).
Some conservatives have Coach Factory Outlet pushed that critique further, saying that Mr. Obama’s policies are too costly, often assist the wrong people Louis Vuitton Belts and could have the paradoxical effect of driving up college costs. The dispute turns not just on different Coach Factory Outlet assessments of how policies play out, but on differing philosophical views about the role of government. During Gucci Belts his time in office, Mr. Obama has sharply increased aid to low- and middle-income students, notably through the Pell Grant Coach Factory Outlet program, which grew from $14.6 billion given to 6 million students in 2008, to nearly $40 billion for Coach Factory Outlet almost 10 million students this year. His administration also made it easier to request aid, shortening the Coach Factory Online complex federal application and allowing people to transfer their financial information electronically from the Internal Coach Outlet Online Revenue Service database. But while many education experts laud his efforts, analysts of varying political Coach Outlet Online stripes have also questioned how much impact some of the president’s policies will have, noting that the prices Coach Online Outlet charged by colleges, and student borrowing, continue to climb.But behind the headlines about soaring costs, the Coach Factory Outlet Online reality is more complex and wildly uneven, because a growing number of students receive Coach Outlet Online financial aid, and only relatively high-income families pay those fast-rising sticker prices. Adjusted for Coach Factory Online inflation, the College Board calculates, the average net price changed little over the last decade at private Coach Factory Outlet schools, and rose only modestly at public ones.Defending federal spending, Arne Duncan, the secretary of Hermes Belts education, said that for more than 30 years, college prices had risen even when federal aid had not, leading him to believe Coach Factory Online there was zero correlation.
Youíve relativelyCoach Outlet recently arrived in New Delhi after living in two of Asiaís other great cities,Coach Outlet Store Online Tokyo and Hong Kong, for several years. Do these cities feel like theyíre part of the same continent? Yes, and no. In terms Coach Factory Onlineof infrastructure, they couldnít be more different. Getting regularCoach Outlet power and water at my house in New Delhi is never a sure thing, even though Coach Purse Outlet OnlineIím paying the same rent that I paid in Tokyo and almost the same electricity prices. Both Hong Kong and Tokyo are also crowded places,Coach Factory Outlet Online but both cities are incredibly well planned and efficiently run. Efficient is not a word I would use to describe my Coach Bags Outlet Onlineday-to-day life in New Delhi. On the other hand, one thing that I think Hong Kong and New Delhi have in common isCoach Handbags Outlet a shared sense of optimism ó a feeling that the best is yet to come. Thatís definitely not the feeling you get in Tokyo,Coach Outlet Online or in the U.S. when I go home. Itís a big part of what I find addictive about living and working in this part of the world. You feel like youíre watching the future unfold.
