App::Sqitch - Sane database change management
use App::Sqitch; exit App::Sqitch->go;
This module provides the implementation for sqitch. You probably want to read its documentation, or the tutorial. Unless you want to hack on Sqitch itself, or provide support for a new engine or command. In which case, you will find this API documentation useful.
sqitch, this class method parses command-line options and arguments in
@ARGV, parses the configuration file, constructs an App::Sqitch object, constructs a command object, and runs it.
my $sqitch = App::Sqitch->new(\%params);
Constructs and returns a new Sqitch object. The supported parameters include:
my $config = $sqitch->config;
Returns the full configuration, combined from the project, user, and system configuration files.
Runs a system command and waits for it to finish. Throws an exception on error.
my @files = $sqitch->capture(qw(ls -lah));
Runs a system command and captures its output to
STDOUT. Returns the output lines in list context and the concatenation of the lines in scalar context. Throws an exception on error.
my $git_version = $sqitch->capture(qw(git --version));
capture, but returns just the
chomped first line of output.
$sqitch->spool($sql_file_handle, 'sqlite3', 'my.db');
Like run, but spools the contents of a file handle to the standard input the system command. Returns true on success and throws an exception on failure.
$sqitch->trace('About to fuzzle the wuzzle.');
Send trace information to
STDOUT if the verbosity level is 3 or higher. Trace messages will have
trace: prefixed to every line. If it's lower than 3, nothing will be output.
$sqitch->debug('Found snuggle in the crib.');
Send debug information to
STDOUT if the verbosity level is 2 or higher. Debug messages will have
debug: prefixed to every line. If it's lower than 2, nothing will be output.
$sqitch->info('Nothing to deploy (up-to-date)');
Send informational message to
STDOUT if the verbosity level is 1 or higher, which, by default, it is. Should be used for normal messages the user would normally want to see. If verbosity is lower than 1, nothing will be output.
$sqitch->comment('On database flipr_test');
Send comments to
STDOUT if the verbosity level is 1 or higher, which, by default, it is. Comments have
# prefixed to every line. If verbosity is lower than 1, nothing will be output.
Send a message to
STDOUT, without regard to the verbosity. Should be used only if the user explicitly asks for output, such as for
sqitch config --get core.editor.
Send a message to
STDERR, without regard to the verbosity. Should be used only for error messages to be printed before exiting with an error, such as when reverting failed changes.
$sqitch->warn('Could not find nerble; using nobble instead.');
Send a warning messages to
STDERR. Warnings will have
warning: prefixed to every line. Use if something unexpected happened but you can recover from it.
Eliminate use of
fail()and localize messages.
Add support for
^and other shortcuts when specifying changes.
