NAME

Vim::Debug - Perl wrapper around a command line debugger

VERSION

version v0.10

SYNOPSIS

    package Vim::Debug;

    my $debugger = Vim::Debug->new(
        language => 'Perl',                    # required
        invoke   => 'perl -Ilib -d t/perl.pl', # required
    );

    $debugger->start;
    sleep(1) until $debugger->read;
    print "line:   " . $debugger->line . "\n";
    print "file:   " . $debugger->file . "\n";
    print "output: " . $debugger->output . "\n";

    $debugger->step;          sleep(1) until $debugger->read;
    $debugger->next;          sleep(1) until $debugger->read;
    $debugger->write('help'); sleep(1) until $debugger->read;

    $debugger->quit;

DESCRIPTION

If you are new to Vim::Debug please read the user manual, Vim::Debug::Manual, first.

Vim::Debug is an object oriented wrapper around the Perl command line debugger. In theory the debugger could be for any language -- not just Perl. But only Perl is supported currently.

The read() method is non blocking. This allows a user to send an interrupt when they get stuck in an infinite loop.

ATTRIBUTES

invoke

language

stop

line

file

value

status

FUNCTIONS

start()

Starts up the command line debugger in a seperate process.

start() always returns undef.

write($command)

Write $command to the debugger's stdin. This method blocks until the debugger process reads. Be sure to include a newline.

write() always returns undef;

read()

Performs a nonblocking read on stdout from the debugger process. read() first looks for a debugger prompt.

If one is not found, the debugger isn't finished thinking so read() returns 0.

If a debugger prompt is found, the output is parsed. The following information is parsed out and saved into attributes: line(), file(), value(), and out().

read() will also send an interrupt (CTL+C) to the debugger process if the stop() attribute is set to true.

out($out)

If called with a parameter, out() removes ornaments (like <CTL-M> or irrelevant error messages or whatever) from text and saves the value.

If called without a parameter, out() returns the saved value.

translate($in)

Translate a protocol command ($in) to a native debugger command. The native debugger command is returned as an arrayref of strings.

Dies if no translation is found.

BUGS

In retrospect its possible there is a better solution to this. Perhaps directly hooking directly into the debugger rather than using regexps to parse stdout and stderr?
