NAME

  LTSV::LINQ - LINQ-style query interface for LTSV files

SYNOPSIS

    use LTSV::LINQ;
    
    # Read LTSV file and query
    my @results = LTSV::LINQ->FromLTSV("access.log")
        ->Where(sub { $_[0]{status} eq '200' })
        ->Select(sub { $_[0]{url} })
        ->Distinct()
        ->ToArray();
    
    # DSL syntax for simple filtering
    my @errors = LTSV::LINQ->FromLTSV("access.log")
        ->Where(status => '404')
        ->ToArray();

DESCRIPTION

LTSV::LINQ provides a LINQ-style query interface for LTSV
(Labeled Tab-Separated Values) files.

ABOUT LINQ

LINQ (Language Integrated Query) is a technology developed by
Microsoft Corporation for the .NET Framework. LINQ(R) is a registered
trademark of Microsoft Corporation.

This module is inspired by LINQ and brings similar query capabilities
to LTSV data processing in Perl. We are grateful to Microsoft for
pioneering this elegant programming pattern.

This module is not affiliated with, endorsed by, or sponsored by
Microsoft Corporation.

WHAT IS LTSV?

LTSV (Labeled Tab-Separated Values) is a format for structured logs.
Each line contains tab-separated key:value pairs.

Example:

    time:2026-02-13T10:00:00	status:200	url:/index.html	bytes:1024
