Introduction

If you're an advanced chess player, you know the importance of having access to a vast library of chess resources. From opening books to game databases, having the right tools at your fingertips can give you the edge you need. One such tool is jja, a command-line utility designed to interact with various chess file formats, making it easier than ever to manage and convert your chess files. In this blog post, we'll dive into the features of jja and how it can help you elevate your chess game.

Key Features

jja is a versatile utility that supports various chess file formats, such as PolyGlot (bin), Arena (abk), ChessBase (ctg), and ChessMaster (obk). The initial intention of the author was to convert their opening books saved in ChessBase's proprietary CTG format to the free and open PolyGlot format. However, as the program evolved, it expanded to include support for other chess file formats, with plans to add even more in the future.
With jja, you can:

1. Read and query multiple opening book formats
2. Convert between different opening book formats, such as CTG to PolyGlot or CTG to Arena
3. Utilize the in-place editing feature for Arena and PolyGlot opening books
4. Search for positions in a chess file
5. Obtain brief information about a chess file

Installation

To install jja, you need the Rust Toolchain. You can compile jja from source using cargo install jja. Alternatively, static builds of jja are available for 64-bit Linux and Windows systems at chesswob.org. You can verify the checksum and GnuPG signature before installation to ensure the integrity of the downloaded files.

Usage

jja allows you to interact with your chess files through various commands. You can use:

1. jja info to get brief information about a chess file
2. jja find to search for a position in a chess file
3. jja edit to edit opening book files and convert to PolyGlot or Arena files

The utility determines the file type based on its file extension. By default, jja displays information using fancy tables. However, you can use the --porcelain command line option to get the output in CSV (comma-separated values) format instead.

I've started hacking this on International Women's Day 2023, a day to honor the achievements of women and advocate for their rights worldwide. As a person of Kurdish heritage, I am particularly moved by the slogan "Woman, Life, Freedom," which has become a symbol of resistance against oppression and a call for equality. In the spirit of free software and free speech, I strive to contribute to the creation of a more just and inclusive society, where every human being is granted the freedom to express themselves and pursue their dreams. I also honor the memory of Mahsa Amini, whose tragic death reminds us of the urgent need to fight for women's freedom and safety.
