About

lssa is a CLI program for the terminal that accepts one or more music artists as arguments and returns a list of similar artists.

By default, the output of each given artist will list 10 similar artists. This number can be set explicitly using the -c|--count=<1-100> option.

The results are sourced from the similar artist pages from last.fm.

Usage

View the usage and help output with the -h|--help flag, or as a plain text file in ./doc/help.txt.

Pre-Build

This section describes what environments this program may run on, any prior requirements or dependencies needed, and any third party libraries used.

Important

Any shell commands using relative paths are expected to be executed in the root directory of this repository.

Environments

• Linux (supported)
• BSD (supported)
• macOS (supported)

Compilers

• GCC >= 8.0.0 (supported)
• Clang >= 7.0.0 (supported)
• Apple Clang >= 11.0.0 (untested)

Dependencies

• CMake >= 3.8
• Boost >= 1.68.0
• ICU >= 62.1
• OpenSSL >= 1.1.0
• PThread
• ZLib

Linked Libraries

• boost_iostreams (libboost_iostreams) part of the Boost library
• boost_system (libboost_system) part of the Boost library
• crypto (libcrypto) part of the OpenSSL library
• icui18n (libicui18n) part of the ICU library
• icuuc (libicuuc) part of the ICU library
• pthread (libpthread) POSIX threads library
• ssl (libssl) part of the OpenSSL library
• z (libz) ZLib library for gzip and deflate compression

Included Libraries

• Belle: HTTP client, modified and included as ./src/ob/belle.hh
• Parg: for parsing CLI args, modified and included as ./src/ob/parg.hh

macOS

Using a new version of GCC or Clang is required, as the default Apple Clang compiler does not support C++17 Standard Library features such as std::filesystem.

A new compiler can be installed through a third-party package manager such as Brew. Assuming you have Brew already installed, the following commands should install the latest GCC.

brew install gcc
brew link gcc

The following CMake argument will then need to be appended to the end of the line when running the shell script. Remember to replace the placeholder <path-to-g++> with the canonical path to the new g++ compiler binary.

./RUNME.sh build -- -DCMAKE_CXX_COMPILER='<path-to-g++>'

Build

The included shell script will build the project in release mode using the build subcommand:

./RUNME.sh build

Install

The included shell script will install the project in release mode using the install subcommand:

./RUNME.sh install
