Bigtop::ScriptHelp::Style::Pg8Live(3) User Contributed Perl Documentation Bigtop::ScriptHelp::Style::Pg8Live(3)
 

Bigtop::ScriptHelp::Style::PgLive - gets its descriptions from Postgresql

For normal use:
    bigtop -n AppName -s Pg8Live \
        'dbi:Pg:dbname=yourdb' user pass [schema]
Do the same for tentmaker. It also works for -a:
    bigtop -a docs/app.bigtop \
        -s Pg8Live 'dbi:Pg:dbname=yourdb' user pass [schema]
Only tables not in docs/app.bigtop will be affected.
For use in scripts:
    use Bigtop::ScriptHelp::Style;
    my $style = Bigtop::ScriptHelp::Style->get_style( 'PgLive' );
    # then pass $style to methods of Bigtop::ScriptHelp

See "Bigtop::ScriptHelp::Style" for a description of what this module must do in general.
This module pulls the database layout from the supplied database. It makes queries on internal postgres tables to retrieve its data. The queries are probably specific to postgres 8.x. They may work for earlier versions, but I wouldn't want to put any money down on that.
This module pulls these things from the database whose dsn you supply:
table names
column names
SQL type of each column
primary keys
column default values
foreign keys

get_db_layout
This method does not use standard in. Instead, it expects these command line arguments (in order):
dsn
Suitable for handing to DBI->connect. Example:
    dbi:Pg:dbname=yourdb
    
database user
password for user
(optional) schema
Defaults to 'public.' Use this if you need to bring in tables from one schema. There is no support for handling multiple schemas with a single invocation, but there is no rule against rerunning with the -a flag to bring in others.
