Hi Everyone, I have: $val="QQ3_1899_CD4". The output will be: 1899. I did $val =~ /(\d+)/g; the output is 318994, then i use substr to get those 1899. This is not efficient. Is any simple way, like just one line can do? Thanks (1 Reply)

NAME
OpenGuides::Test - Methods to help test OpenGuides applications. DESCRIPTION
Provides methods to help when writing tests for OpenGuides. Distributed and installed as part of the OpenGuides project, not intended for independent installation. This documentation is probably only useful to OpenGuides developers. SYNOPSIS
use OpenGuides; use OpenGuides::Test; OpenGuides::Test::refresh_db(); my $config = OpenGuides::Test->make_basic_config; $config->default_language( "nl" ); my $guide = OpenGuides->new( config => $config ); OpenGuides::Test->write_data( guide => $guide, node => "Crabtree Tavern", os_x => 523465, os_y => 177490, categories => "Pubs", ); METHODS
make_basic_config my $config = OpenGuides::Test->make_basic_config; $config->default_language( "nl" ); Makes an OpenGuides::Config object with needed fields pre-filled. You can mess with it as you like then. write_data my $config = OpenGuides::Test->make_basic_config; my $guide = OpenGuides->new( config => $config ); OpenGuides::Test->write_data( guide => $guide, node => "Crabtree Tavern", os_x => 523465, os_y => 177490, categories => "Pubs Pub Food", ); This method calls the "make_cgi_object" method to make its CGI object; you can supply values for any key mentioned there. You should supply them exactly as they would come from a CGI form, eg lines in a textarea are separated by " ". This method will automatically grab the checksum from the database, so even if the node already exists your data will still be written. If you don't want this behaviour (for example, if you're testing edit conflicts) then pass in a true value to the "omit_checksum" parameter: OpenGuides::Test->write_data( guide => $guide, node => "Crabtree Tavern", omit_checksum => 1, ); If you want to grab the output, pass a true value to "return_output": my $output = OpenGuides::Test->write_data( guide => $guide, node => "Crabtree Tavern", return_output => 1, ); Similarly, if you pass a true value to "return_tt_vars", the return value will be the variables which would have been passed to the template for output: my %vars = OpenGuides::Test->write_data( guide => $guide, node => "Crabtree Tavern", return_tt_vars => 1, ); make_cgi_object my $q = OpenGuides::Test->make_cgi_object; You can supply values for the following keys: "content", "categories", "locales", "node_image", "node_image_licence", "node_image_copyright", "node_image_url", "phone", "fax", "website", "hours_text", "address", "postcode", "map_link", "os_x", "os_y", "osie_x", "osie_y", "latitude", "longitude", "summary", "username", "comment", "edit_type". You should supply them exactly as they would come from a CGI form, eg lines in a textarea are separated by " ". refresh_db Openguides::Test::refresh_db(); Unlink the existing SQLite database t/node.db and plucene indexes. Then create a new SQLite database t/node.db AUTHOR
