NAME

       App::Info::RDBMS::SQLite - Information about SQLite

SYNOPSIS

         use App::Info::RDBMS::SQLite;

         my $sqlite = App::Info::RDBMS::SQLite->new;

         if ($sqlite->installed) {
             print "App name: ", $sqlite->name, "\n";
             print "Version:  ", $sqlite->version, "\n";
             print "Bin dir:  ", $sqlite->bin_dir, "\n";
         } else {
             print "SQLite is not installed. :-(\n";
         }

DESCRIPTION

       App::Info::RDBMS::SQLite supplies information about the SQLite application installed on
       the local system. It implements all of the methods defined by App::Info::RDBMS. Methods
       that trigger events will trigger them only the first time they're called (See App::Info
       for documentation on handling events). To start over (after, say, someone has installed
       SQLite) construct a new App::Info::RDBMS::SQLite object to aggregate new meta data.

       Some of the methods trigger the same events. This is due to cross-calling of shared
       subroutines. However, any one event should be triggered no more than once. For example,
       although the info event "Executing `pg_config --version`" is documented for the methods
       "name()", "version()", "major_version()", "minor_version()", and "patch_version()", rest
       assured that it will only be triggered once, by whichever of those four methods is called
       first.

INTERFACE

   Constructor
       new

         my $sqlite = App::Info::RDBMS::SQLite->new(@params);

       Returns an App::Info::RDBMS::SQLite object. See App::Info for a complete description of
       argument parameters.

       When it called, "new()" searches the directories returned by search_bin_dirs for an
       executable with a name returned by "search_exe_names". If found, it will be called by the
       object methods below to gather the data necessary for each. If it cannot be found, then
       "new()" will attempt to load DBD::SQLite or DBD::SQLite2. These DBI drivers have SQLite
       embedded in them but do not install the application. If these fail, then SQLite is assumed
       not to be installed, and each of the object methods will return "undef".

       Events:

       info
           Looking for SQLite.

       confirm
           Path to SQLite executable?

       unknown
           Path to SQLite executable?

   Class Method
       key_name

         my $key_name = App::Info::RDBMS::SQLite->key_name;

       Returns the unique key name that describes this class. The value returned is the string
       "SQLite".

   Object Methods
       installed

         print "SQLite is ", ($sqlite->installed ? '' : 'not '), "installed.\n";

       Returns true if SQLite is installed, and false if it is not.

       App::Info::RDBMS::SQLite determines whether SQLite is installed based on the presence or
       absence of the sqlite3 or sqlite application on the file system as found when "new()"
       constructed the object. If SQLite does not appear to be installed, then all of the other
       object methods will return empty values.

       name

         my $name = $sqlite->name;

       Returns the name of the application. App::Info::RDBMS::SQLite simply returns the value
       returned by "key_name" if SQLite is installed, and "undef" if it is not installed.

       version

         my $version = $sqlite->version;

       Returns the SQLite version number. App::Info::RDBMS::SQLite parses the version number from
       the system call "`sqlite -version`" or retrieves it from DBD::SQLite.

       Events:

       info
           Executing `sqlite -version`

       error
           Failed to find SQLite version with `sqlite -version`

           Failed to retrieve SQLite version from DBD::SQLite

           Unable to parse name from string

           Unable to parse version from string

           Failed to parse SQLite version parts from string

       unknown
           Enter a valid SQLite version number

       major version

         my $major_version = $sqlite->major_version;

       Returns the SQLite major version number. App::Info::RDBMS::SQLite parses the version
       number from the system call "`sqlite -version`" or retrieves it from DBD::SQLite. For
       example, if "version()" returns "3.0.8", then this method returns "3".

       Events:

       info
           Executing `sqlite -version`

       error
           Failed to find SQLite version with `sqlite -version`

           Failed to retrieve SQLite version from DBD::SQLite

           Unable to parse name from string

           Unable to parse version from string

           Failed to parse SQLite version parts from string

       unknown
           Enter a valid SQLite version number

       minor version

         my $minor_version = $sqlite->minor_version;

       Returns the SQLite minor version number. App::Info::RDBMS::SQLite parses the version
       number from the system call "`sqlite -version`" or retrieves it from DBD::SQLite. For
       example, if "version()" returns "3.0.8", then this method returns "0".

       Events:

       info
           Executing `sqlite -version`

       error
           Failed to find SQLite version with `sqlite -version`

           Failed to retrieve SQLite version from DBD::SQLite

           Unable to parse name from string

           Unable to parse version from string

           Failed to parse SQLite version parts from string

       unknown
           Enter a valid SQLite version number

       patch version

         my $patch_version = $sqlite->patch_version;

       Returns the SQLite patch version number. App::Info::RDBMS::SQLite parses the version
       number from the system call "`sqlite -version`" or retrieves it from DBD::SQLite. For
       example, if "version()" returns "3.0.8", then this method returns "8".

       Events:

       info
           Executing `sqlite -version`

       error
           Failed to find SQLite version with `sqlite -version`

           Failed to retrieve SQLite version from DBD::SQLite

           Unable to parse name from string

           Unable to parse version from string

           Failed to parse SQLite version parts from string

       unknown
           Enter a valid SQLite version number

       executable

         my $executable = $sqlite->executable;

       Returns the path to the SQLite executable, usually sqlite3 or sqlite, which will be
       defined by one of the names returned by"search_exe_names()".  The executable is searched
       for in "new()", so there are no events for this method.

       bin_dir

         my $bin_dir = $sqlite->bin_dir;

       Returns the SQLite binary directory path. App::Info::RDBMS::SQLite simply retrieves it as
       the directory part of the path to the SQLite executable.

       lib_dir

         my $lib_dir = $expat->lib_dir;

       Returns the directory path in which an SQLite library was found. The directory path will
       be one of the values returned by "search_lib_dirs()", where a file with a name as returned
       by "search_lib_names()" was found. No search is performed if SQLite is not installed or if
       only DBD::SQLite is installed.

       Events:

       info
           Searching for shared object library directory

       error
           Cannot find shared object library directory

       unknown
           Enter a valid Expat shared object library directory

       so_lib_dir

         my $so_lib_dir = $expat->so_lib_dir;

       Returns the directory path in which an SQLite shared object library was found. The
       directory path will be one of the values returned by "search_lib_dirs()", where a file
       with a name as returned by "search_so_lib_names()" was found. No search is performed if
       SQLite is not installed or if only DBD::SQLite is installed.

       Events:

       info
           Searching for shared object library directory

       error
           Cannot find shared object library directory

       unknown
           Enter a valid Expat shared object library directory

       inc_dir

         my $inc_dir = $sqlite->inc_dir;

       Returns the directory path in which an SQLite include file was found. The directory path
       will be one of the values returned by "search_inc_dirs()", where a file with a name as
       returned by "search_inc_names()" was found. No search is performed if SQLite is not
       installed or if only DBD::SQLite is installed.

       Events:

       info
           Searching for include directory

       error
           Cannot find include directory

       unknown
