Usage (from gitolite clone directory):
./install
to run gitolite using an absolute or relative path, for example
'src/gitolite' or '/full/path/to/this/dir/src/gitolite'
./install -ln [<dir>]
to symlink just the gitolite executable to some <dir> that is in
$PATH. <dir> defaults to $HOME/bin if <dir> not specified. <dir> is
assumed to exist; gitolite will not create it.
Please provide a full path, not a relative path.
./install -to <dir>
to copy the entire 'src' directory to <dir>. If <dir> is not in
$PATH, use the full path to run gitolite commands.
Please provide a full path, not a relative path.
<perl-executable> ./install -to <dir>
to copy the entire 'src' directory to <dir>, but will replace
all of the shebangs with the path to <perl-executable>. This
is a way to force gitolite to use some perl that is not
installed at /usr/bin/perl.
Simplest use, if $HOME/bin exists and is in $PATH, is:
git clone https://github.com/sitaramc/gitolite
gitolite/install -ln
# now run setup
gitolite setup -pk /path/to/YourName.pub
=cut
my ( $to, $ln, $help, $quiet );
GetOptions(
'to=s' => \$to,
'ln:s' => \$ln,
'help|h' => \$help,
'quiet|q' => \$quiet,
);
usage() if $to and $ln or $help;
$ln = "$ENV{HOME}/bin" if defined($ln) and not $ln;
for my $d ($ln, $to) {
next unless $d; # ignore empty values
unless ( $d =~ m(^/) ) {
print STDERR "FATAL: please use an absolute path, not a relative path\n";
usage();
}
if ( not -d $d ) {
print STDERR "FATAL: '$d' does not exist.\n";
usage();
}
}
chdir($ENV{GL_BINDIR});
my $version = `git describe --tags --long --dirty=-dt 2>/dev/null`;
unless ($version =~ /^v\d/) {
print STDERR "git describe failed; cannot deduce version number\n";
$version = "(unknown)";
}
if ($to) {
_mkdir($to);
system("cp -RpP * $to");
_print( "$to/VERSION", $version );
# Replace shebangs if necessary.
my $thisperl = $Config{perlpath};
if ($thisperl ne '/usr/bin/perl') {
system("cd $to; grep -r -l /usr/bin/perl | xargs perl -pi -e 's(^#!/usr/bin/perl)(#!$thisperl)'");
}
} elsif ($ln) {
ln_sf( $ENV{GL_BINDIR}, "gitolite", $ln );
_print( "VERSION", $version );
} else {
say "use the following full path for gitolite:";
