CGI/WebOut ========== The README is used to introduce the module and provide instructions on how to install the module, any machine dependencies it may have (for example C compilers and installed libraries) and any other information that should be provided before the module is installed. A README file is required for CPAN modules since CPAN extracts the README file from a module distribution so that people browsing the archive can use it get an idea of the modules uses. It is usually a good idea to provide version information here so that people can decide whether fixes for the module are worth downloading. INSTALLATION To install this module type the following: perl Makefile.PL make make test make install SYNOPSIS # Simple CGI script (no 500 Apache error!) use CGI::WebOut; print "Hello world!"; # wow, we may NOT output Content-type! # Handle output for {}-block my $str=grab { print "Hi there!\n"; }; $str=~s/\n/
/sg; print $str; DESCRIPTION CGI::WebOut - Perl extension for handle CGI output (in PHP-style) This module is used to make CGI programmer's work more comfortable. The main idea is to handle output stream (STDOUT) to avoid any data to be sent to browser without Content-type header. Of cource, you may also send your own headers to browser using Header(). Any errors will be printed at the bottom of page "in PHP-style". You may also use Carp module together with CGI::WebOut. You may also handle any program block's output (using print etc.) and place it to the variable using grab {...} subroutine. It is a very useful feature for lots of CGI-programmers. The last thing - support for try-catch "instruction". WARNING: this is NOT tre real instruction, like map {...}, grep {...} etc.! Be careful with return instruction in try-catch blocks. Note: you may use CGI::WebOut not only for CGI scripts. In "non-CGI" script headers are NOT output, and warnings are shown as plain-text. grab {...}, try-catch etc. work as usual.
