If this is the input kk.java:
public class test {
public static final test alpha = new test("foo", "bar");
public static final test beta = new test("baz", "boo");
}
public class test2 {
public static final test2 alpha2 = new test2("foo", "bar");
public static final test2 beta2 = new test2("baz", "boo");
public static final test alpha = new test("foo", "bar");
public static final test beta = new test("baz", "boo");
}
And this the code one line:
perl -MData::Dumper -le 'undef $/;$javafile = <>; while ( $javafile =~
+ / class (\w+) (.*?)^\}/smg ) { ($class,$body) = ($1,$2); while ( $bo
+dy =~ /(\w+)\s*=\s*new\s+$class\s*\((.*)\)/g) { ($variable,$parameter
+s)=($1,$2); foreach $v (split",",$parameters){ $v =~ s/[ "]//g; push
+@{$var{$class}{$variable}},$v } } }; print Dumper %var ' kk.java
this is the result:
$VAR1 = 'test';
$VAR2 = {
'alpha' => [
'foo',
'bar'
],
'beta' => [
'baz',
'boo'
]
};
$VAR3 = 'test2';
$VAR4 = {
'alpha2' => [
'foo',
'bar'
],
'beta2' => [
'baz',
'boo'
]
};
Updated:
Not oneline version:
#!/usr/bin/perl
use Data::Dumper;
use diagnostics;
use warnings;
use strict;
undef $/;
my %vars; # My vars space
my $javafile = <>; # Read the java src
# Read all class' bodies
while ( $javafile =~ / class (\w+) (.*?)^\}/smg ) {
my ($class,$body) = ($1,$2);
# Read all vars' declarations
while ( $body =~ /(\w+)\s*=\s*new\s+$class\s*\((.*)\)/g) {
my ($variable,$parameters)=($1,$2);
# Split parameters
foreach my $v ( split ",",$parameters ) {
# Filter bad characters
$v =~ s/[ \"]//g;
# Parameters falling into the black hole
push @{ $vars{$class}{$variable} }, $v;
}
}
}
# Out of the space
print Dumper %vars;
Updated. Edited for last test.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>

-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
