##
## cgitrc: template for /etc/cgitrc
##


## Uncomment and set to 1 to deactivate caching of generated pages. Mostly
## usefull for testing.
#nocache=0


## Enable/disable snapshots by default. This can be overridden per repo
#snapshots=0


## Specify a root for virtual urls. This makes cgit generate urls like
##
##    http://localhost/git/repo/log/?id=master
##
## instead of
##
##    http://localhost/cgit/cgit.cgi?r=repo&p=log&id=master
##
## For this to work with apache, rewrite rules must be added to httpd.conf,
## possibly looking something like this:
##
##   RewriteRule ^/git/$ /cgit/cgit.cgi                            [L,QSA]
##   RewriteRule ^/git/([^/]+)/$ /cgit/cgit.cgi?r=$1               [L,QSA]
##   RewriteRule ^/git/([^/]+)/([^/]+)/$ /cgit/cgit.cgi?r=$1&p=$2  [L,QSA]
##
## This setting is disabled by default.
#virtual-root=/git


## Set the title printed on the root page
#root-title=Git repository browser


## Link to css file
#css=/cgit/cgit.css


## Link to logo file
#logo=/cgit/git-logo.png


## Url loaded when clicking the logo
#logo-link=http://www.kernel.org/pub/software/scm/git/docs/


## Url loaded when clicking a submodule link
#module-link=./?repo=%s&page=commit&id=%s


## Number of chars shown of commit subject message (in log view)
#max-message-length=60


## Root of cached output
#cache-root=/var/cache/cgit


##
## Time-To-Live settings: specifies how long (in minutes) different pages 
## should be cached (0 for instant expiration, -1 for immortal pages)
##

## ttl for root page
#cache-root-ttl=5

## ttl for repo summary page
#cache-repo-ttl=5

## ttl for other dynamic pages 
#cache-dynamic-ttl=5

## ttl for static pages (addressed by SHA-1)
#cache-static-ttl=-1



## Example repository entry. Required values are repo.url and repo.path (each
## repository section must start with repo.url).
#repo.url=cgit
#repo.name=cgit
#repo.desc=the caching cgi for git
#repo.path=/pub/git/cgit
#repo.owner=Lars Hjemli
#repo.snapshots=1				# override a sitewide snapshot-setting
#repo.module-link=/git/%s/commit/?id=%s		# override the standard module-link
