Text::Parser is a bare-bones text parsing class. It is ignorant of the text format, and cannot recognize any grammars, but derived classes that inherit from it can specify this. They can do this usually by overriding just one of the methods in this class.
Future versions are expected to include progress-bar support, parsing text from sockets, or a chunk of memory. All these software features are text-format independent and can be re-used in parsing any text format. Derived classes of Text::Parser will be able to take advantage of these features.
A perl module that redirects output log messages into specific log files
using simply the
warn()' built-in Perl
sub-routines. The interface allows a programmer to simply write the
messages he wants to produce usingprint()',
printf' orwarn', and
let a different portion of the code take care of where it gets written
to. This has a couple of advantages:
1. It allows the program to be independent of the names for the logfiles, and allows the user to choose his names 2. It is very easy to make a message appear on screen as well as in a file, without repeating the print statement - this is done using the `verbose' option. 3. No special logging functions need to be used. The standard `print', `printf' and `warn' functions do the job. 4. Works correctly even if used with `fork()'.
Writing logs have become exceedingly hard, when in reality it is a rather simple task: tell the user what is going on. Most modules allow one to write log messages with message levels and stuff. But sometimes they are not useful, and sometimes the modules just do not cover all the message levels that one may want. The end result is that a programmer has to take special care to choose a good logging interface and that takes time away from his core work - writing the algorithm. `Log::Redirect' allows a programmer to think of the algorithm first, and log messages later. It also allows for a very easy way to display the log on screen and simultaneously writing to the file. `Log::Redirect' also writes to the disk instantly and doesn't wait for the buffer to be full before it begins writing something.
new Creates a new object of this class. It requires a filename as a required argument. In addition, it can accept an optional parameter my $mylog = Log::Redirect->new('mylog.log'); my $verboselog = Log::Redirect->new('verbose.log', verbose => 1);
None by default.
