Complex repository layout: defining the branch regular expression string

[trac@…]

Description

I want to use the plugin, but we have the following repo layout which produces an error. I tried to understand the regex for custom layout but failed, perhaps you can help me.

Repo layout

+--+ app1
|  |
|  +--+ project_1
|  |  +--+ trunk
|  |  +--+ branches
|  |  +--+ tags
|  |
|  +--+ project_2
|     +--+ trunk
|     +--+ branches
|     +--+ tags
|
+--+ app2
|  |
|  +--+ project_1
|  |  +--+ trunk
|  |  +--+ branches
|  |  +--+ tags
|  |
|  +--+ project_2
|     +--+ trunk
|     +--+ branches

Replying to trac@grunewaldt.net:

I want to use the plugin, but we have the following repo layout which produces an error. I tried to understand the regex for custom layout but failed, perhaps you can help me.

Try the following regular expression:

branch_re = ^(?P<branch>[^/]+/[^/]+/(?:(?:tags|branches)/[^/]+|trunk))(?:/(?P<path>.*))?$

or if you want to get shorten the branch name and you can afford masking the application name

branch_re = ^(?P<branch>[^/]+/(?P<branchname>[^/]+/(?:(?:tags|branches)/[^/]+|trunk)))(?:/(?P<path>.*))?$

Note that the second RE as defined in the previous comment requires a 0.6.x plugin.

eblot could you please provide an explanation for the branch_re in the plugin wiki page, I think it would be very useful for people like us who have complex repository structures, because AFAIK there is no place where the purpose of the regexp is explained.

Thanks.
