.Nm
.Op Fl dnv
.Op Fl D Ar macro Ns = Ns Ar value
.Op Fl f Ar file
.Sh DESCRIPTION
.Nm
is a FastCGI server program which can display the contents of Git
repositories via a web browser.
The program has been designed to work out of the box with
the
.Xr httpd 8
web server.
.Pp
.Nm
provides the following options:
.Bl -tag -width tenletters
.It Fl d
Do not daemonize.
Send log output to stderr.
.It Fl D Ar macro Ns = Ns Ar value
Define
.Ar macro
to be set to
.Ar value .
Overrides the definition of
.Ar macro
in the configuration file.
.It Fl f Ar file
Set the path to the configuration file.
If not specified, the file
.Pa /etc/gotwebd.conf
will be used.
.It Fl n
Parse the configuration file, report errors if any, and exit.
.It Fl v
Verbose mode.
Verbosity increases if this option is used multiple times.
.El
.Pp
Enabling
.Nm
requires the following steps:
.Bl -enum
.It
The
.Xr httpd.conf 5
configuration file must be adjusted to run
.Nm
as a FastCGI helper program.
The
.Sx EXAMPLES
section below contains an appropriate configuration file sample.
.It
httpd(8) must be enabled and started:
.Bd -literal -offset indent
  # rcctl enable httpd
  # rcctl start httpd
.Ed
.It
Optionally, the run-time behaviour of
.Nm
can be configured via the
.Xr gotwebd.conf 5
configuration file.
.It
Git repositories must be created at a suitable location inside the
web server's
.Xr chroot 2
environment.
These repositories should
.Em not
be writable by the user ID shared between
.Nm
and
.Xr httpd 8 .
The default location for repositories published by
.Nm
is
.Pa /var/www/got/public .
.It
Git repositories served by
.Nm
should be kept up-to-date with a mechanism such as
.Cm got fetch ,
.Xr git-fetch 1 ,
or
.Xr rsync 1 ,
scheduled by
.Xr cron 8 .
.El
.Sh FILES
.Bl -tag -width /var/www/got/public/ -compact
.It Pa /etc/gotwebd.conf
Default location of the
.Xr gotwebd.conf 5
configuration file.
.It Pa /var/www/got/public/
Default location for Git repositories served by
.Nm .
This location can be adjusted in the
.Xr gotwebd.conf 5
configuration file.
.It Pa /var/www/bin/gotwebd/
Directory containing statically linked
.Xr got 1
helper programs which are run by
.Nm
to read Git repositories.
.It Pa /var/www/htdocs/gotwebd/
Directory containing HTML, CSS, and image files used by
.Nm .
.It Pa /tmp/
Directory for temporary files created by
.Nm .
.El
.Sh EXAMPLES
Example configuration for
.Xr httpd.conf 5 :
.Bd -literal -offset indent
  types { include "/usr/share/misc/mime.types" }

  # one gotwebd reachable at http://gotweb1.example.com/
  server "gotweb1.example.com" {
        listen on * port 80
        root "/htdocs/gotwebd"
        location "/" {
              fastcgi socket "/run/gotweb.sock"
        }
  }

  # hosting multiple gotwebd instances on the same HTTP server:
  # http://gotweb2.example.com/gotwebd-unix/
  # http://gotweb2.example.com/gotwebd-tcp/
  server "gotweb2.example.com" {
        listen on * port 80
        location "/gotwebd-unix/" {
              fastcgi socket "/run/gotweb.sock"
        }
        location "/gotwebd-unix/*" {
               root "/htdocs/gotwebd"
               request strip 1
        }
        location "/gotwebd-tcp/" {
              fastcgi socket tcp 127.0.0.1 9000
        }
        location "/gotwebd-tcp/*" {
               root "/htdocs/gotwebd"
               request strip 1
        }
