Hook svnperms , svnperms.conf syntax .

[Annick Collet <An...@eumetsat.int>]

Dear all, 

In the acces right file svnperms.conf , can someone explain me the syntax of the command .
So what is the difference between  1 and 2 : 

1
trunk/project1/.+ = @project1(add,remove,update)
trunk/project2/.+ = @project2(add,remove,update)

2
trunk/project1/[^/]+/ = @project1(add,remove,update)
trunk/project2/[^/]+/ = @project2(add,remove,update)


thanks, Ann.

The part before the "=" is a regular expression. Regular expressions  
are a very powerful way to match parts of text, but are also pretty  
difficult to get the hang of. Documentation is plentiful, but also  
long, if you want to understand it all.

Just enough to understand what's written here:

. matches any character.
+ matches one or more of the preceding.
So .+ matches one or more of any character.

Square brackets define  set of characters, and matches any one of them.
A ^ at the beginning of a set of characters negates it, matching  
anything that's not in the range.
So [^/]+ matches one or more chacacters that are not slashes.

So, the first set of rules above allows you to add, remove or update  
anything within project1 or project2, while the second set allows you  
to add, remove or update anything inside any directory inside  
project1 or project2, but not anything directly inside project1 or  
project2's root directory.
