LRC-Tools

Tools for parsing and playing back LRC lyrics.

Usage

// Parsing file.
lrc::LrcParser parser;

// You may also use ParseString to parse a string or ParseStream to parse from an istream.
std::unique_ptr<lrc::Lyrics> lyrics = parser.ParseFile(filename);

// Getting metadata.
const lrc::Lyrics::Metadata& metadata = lyrics->GetMetadata();
std::cout << "Title: " << metadata.title << std::endl
          << "Album: " << metadata.album << std::endl
          << "Artist: " << metadata.artist << std::endl
          << "Adjustment: " << metadata.adjustment << std::endl;

// Printing lyric and other information.
const lrc::Lyrics::LyricLine& line =
    lyrics->LyricAt(lrc::utils::TimeStringToMilliseconds("01:18.29"));
std::cout << "Start time: " << line.start_time << "\t"
          << "End time: " << line.end_time << "\t"
          << "Lyric: " << line.lyric;

// Printing lyrics around current lyric.
lrc::Lyrics::ConstLyricIterator iter = lyrics->LyricAt(78290);
//   Previous lyric
// > Current lyric
//   Next lyric
std::cout << "  " << (iter - 1)->lyric << std::endl
          << "> " << iter->lyric << std::endl
          << "  " << (iter + 1)->lyric << std::endl;

You may also see code in cli/ as an example.

Requirements

• Compiler that supports C++11 standard.
• CMake > 3.2.

Project Structure

• liblrc: Library for parsing LRC files and looking up lyrics at a given time.
• cli: Command line tools for querying LRC metadata or lyrics at a given time. Depends on liblrc.

Building

In project root directory:

$ mkdir build
$ cd build
$ cmake ..
$ make

Then libraries and programs will be built in their corresponding directory inside build/.

Testing

Follow all the steps in Building, then run:

$ make test
