"Subversion" is the version control system used in the php-tsql project. To contribute to it we have to use the subversion(svn) client in our local machine. This article includes the basic usage of subversion.
To install subversion,
sudo apt-get install subversion
To download the project's source files, you should create a directory somewhere in your
machine and go into that directory from shell,
Now give the command,
sudo svn checkout http://path to the project
sudo svn checkout http://188.8.131.52/svn/php-tsql/trunk
Now you can do editing of your files. But when you add or delete files/folders to the source directory you have to do it also in the command line.
To add a new file or directory to the source directory,
sudo svn add path/fileOrFoldername
(you're in the directory which you created to get the source files)
sudo svn add trunk/newfile.c
sudo svn add trunk/newDirectory
sudo svn add trunk/newDirectory/newfile2.c
You can delete a file or folder in a similar way,
sudo svn delete trunk/newfile2.c
sudo svn delete trunk/newDirectory
After you're done with the editing of source code, you have to commit it back to the repository.
sudo svn commit trunk/
When we commit we can put a log message which may be useful to track the purpose of editing the source of previous committed revision. To add the log message,
sudo svn commit trunk/ --message "This is the log message."
There are lot's of svn command available, following links will be helpful.
