A mask of snapshot formats for this repo that cgit generates links for, restricted by the global "snapshots" setting\&. Default value: <snapshots>\&.
.RE
.PP
repo\&.snapshot\-prefix
.RS 4
Prefix to use for snapshot links instead of the repository basename\&. For example, the "linux\-stable" repository may wish to set this to "linux" so that snapshots are in the format "linux\-3\&.15\&.4" instead of "linux\-stable\-3\&.15\&.4"\&. Default value: <empty> meaning to use the repository basename\&.

.RE
.SH "REPOSITORY\-SPECIFIC CGITRC FILE"
.sp
When the option "scan\-path" is used to auto\-discover git repositories, cgit will try to parse the file "cgitrc" within any found repository\&. Such a repo\-specific config file may contain any of the repo\-specific options described above, except "repo\&.url" and "repo\&.path"\&. Additionally, the "filter" options are only acknowledged in repo\-specific config files when "enable\-filter\-overrides" is set to "1"\&.
.sp
Note: the "repo\&." prefix is dropped from the option names in repo\-specific config files, e\&.g\&. "repo\&.desc" becomes "desc"\&.
.SH "FILTER API"
.sp
By default, filters are separate processes that are executed each time they are needed\&. Alternative technologies may be used by prefixing the filter specification with the relevant string; available values are:
.PP
\fIexec:\fR
.RS 4
The default "one process per filter" mode\&.
.RE
.PP
\fIlua:\fR
.RS 4
Executes the script using a built\-in Lua interpreter\&. The script is loaded once per execution of cgit, and may be called multiple times during cgit\(cqs lifetime, making it a good choice for repeated filters such as the
\fIemail filter\fR\&. It responds to three functions:
.RE
.PP
\fIfilter_open(argument1, argument2, argument3, \&...)\fR
.RS 4
This is called upon activation of the filter for a particular set of data\&.
.RE
.PP
\fIfilter_write(buffer)\fR
.RS 4
This is called whenever cgit writes data to the webpage\&.
.RE
.PP
\fIfilter_close()\fR
.RS 4
This is called when the current filtering operation is completed\&. It must return an integer value\&. Usually 0 indicates success\&.
.sp

.SH "CACHE"
.sp
All cache ttl values are in minutes\&. Negative ttl values indicate that a page type will never expire, and thus the first time a URL is accessed, the result will be cached indefinitely, even if the underlying git repository changes\&. Conversely, when a ttl value is zero, the cache is disabled for that particular page type, and the page type is never cached\&.
.SH "SIGNATURES"
.sp
Cgit can host \&.asc signatures corresponding to various snapshot formats, through use of git notes\&. For example, the following command may be used to add a signature to a \&.tar\&.xz archive:
.sp
.if n \{\
.RS 4
.\}
.nf
git notes \-\-ref=refs/notes/signatures/tar\&.xz add \-C "$(
    gpg \-\-output \- \-\-armor \-\-detach\-sign cgit\-1\&.1\&.tar\&.xz |
    git hash\-object \-w \-\-stdin
)" v1\&.1
.fi
.if n \{\
.RE
.\}
.sp
If it is instead desirable to attach a signature of the underlying \&.tar, this will be linked, as a special case, beside a \&.tar\&.* link that does not have its own signature\&. For example, a signature of a tarball of the latest tag might be added with a similar command:
.sp
.if n \{\
.RS 4
.\}
.nf
tag="$(git describe \-\-abbrev=0)"
git notes \-\-ref=refs/notes/signatures/tar add \-C "$(
    git archive \-\-format tar \-\-prefix "cgit\-${tag#v}/" "$tag" |
    gpg \-\-output \- \-\-armor \-\-detach\-sign |
    git hash\-object \-w \-\-stdin
)" "$tag"
.fi
.if n \{\
.RE
.\}
.sp
Since git\-archive(1) is expected to produce stable output between versions, this allows one to generate a long\-term signature of the contents of a given tag\&.
