我有两个从IntexCalc和Intex API生成的文件,我想比较它们的内容。我不想逐行比较。下面的例子将提供有关它的更多细节。
LOSS_USERCURVE_TYPE[\"GRPY\"]=PCT_MULTIPLY
LOSS_NONPERF_ADV_PCT_P[\"GRPY\"]=0
LOSS_UNITS[\"GRPY\"]=CDR
LOSS_NONPERF_ADV_PCT_I[\"GRPY\"]=0
SEVERITY_USERCURVE_TYPE[\"GRPY\"]=NONE
LOSS_SEVERITY[\"GRPY\"]=31.73
LOSS_USERCURVE_INDEX_OFFSET[\"GRPY\"]=BY_DEAL_AGE
LOSS_UNITS[\"GRPY\"]
我想比较两个文件中的LOSS_USERCURVE_INDEX_OFFSET[\"GRPY\"]
标志值。在两个文件中,无论它们在文件中的位置如何,它们在= / ==之后的值都是相同的,因此该标志值是相等的。
文件1中BY_LOAN_AGE
的标记值为BY_DEAL_AGE
,文件2中的标记值为LOSS_RATE[\"GRPY\"]
,因此该标记值不同。
标志LOSS_SEVERITY[\"GRPY\"]
仅出现在文件1中,因此这是一个区别
标志{{1}}仅出现在文件2中,因此这也是一个区别。
比较这种文件结构的最佳方法或工具是什么?

我建议您使用Data::Diff
模块
它返回对包含参数之间差异摘要的哈希的引用。键是
same
- 两种情况下相同的元素diff
- 给定键具有不同值的元素uniq_a
和uniq_b
- 仅出现在一个结构或另一个结构中的元素
use strict;
use warnings 'all';
use autodie;
use Data::Dump;
use Data::Diff 'Diff';
my %f1 = do {
open my $fh, '<', 'file1.txt';
map { s/\s+\z//; split /=+/, $_, 2 } <$fh>;
};
my %f2 = do {
open my $fh, '<', 'file2.txt';
map { s/\s+\z//; split /=+/, $_, 2 } <$fh>;
};
my $diff = Diff(\(%f1, %f2));
dd $diff;
{
diff => {
"LOSS_USERCURVE_INDEX_OFFSET[\\\"GRPY\\\"]" => { diff_a => "BY_LOAN_AGE", diff_b => "BY_DEAL_AGE", type => "" },
},
same => {
"LOSS_NONPERF_ADV_PCT_I[\\\"GRPY\\\"]" => { same => 0, type => "" },
"LOSS_NONPERF_ADV_PCT_P[\\\"GRPY\\\"]" => { same => 0, type => "" },
"LOSS_UNITS[\\\"GRPY\\\"]" => { same => "CDR", type => "" },
"LOSS_USERCURVE_TYPE[\\\"GRPY\\\"]" => { same => "PCT_MULTIPLY", type => "" },
"SEVERITY_USERCURVE_TYPE[\\\"GRPY\\\"]" => { same => "NONE", type => "" },
},
type => "HASH",
uniq_a => { "LOSS_RATE[\\\"GRPY\\\"]" => 100 },
uniq_b => { "LOSS_SEVERITY[\\\"GRPY\\\"]" => 31.73 },
}

一个没有灵感的解决方案:将键和值放入两个哈希值并进行比较。
sub f2h {
my( $hr, $path ) = @_;
open FILE, $path or die "$path: couldn't open: $!";
while( my $line = <FILE> ){
$line =~ s/\s+$//; # there are trailing spaces in your data
my( $key, $val ) = split( /==?/, $line );
$hr->{$key} = $val;
}
close FILE;
}
my %h1;
my %h2;
f2h( \%h1, "file1.dat" );
f2h( \%h2, "file2.dat" );
while( my( $k, $v ) = each %h1 ){
if( exists( $h2{$k} ) ){
print "different $k\n" if $h2{$k} ne $v;
} else {
print "$k missing in 2\n";
}
}
while( my( $k, $v ) = each %h2 ){
print "$k missing in 1\n" unless exists $h1{$k};
}
