The authoritative book ‘Mastering Dyalog APL’ is being updated with new online and interactive content to reflect recent changes in Dyalog APL. The current online version is a work in progress, with plans for a printed edition.
The first edition of ‘Mastering Dyalog APL,’ a key resource for learning the programming language, is being actively revised and expanded to include interactive tools and updated content, as the original becomes increasingly outdated.
The original ‘Mastering Dyalog APL,’ authored by Bernard Legrand and published in 2009, remains a foundational resource for learners. However, as Dyalog APL has evolved, the book’s static online version is now a work in progress, with ongoing revisions and missing sections. A new, more interactive version is being developed using Jupyter Notebooks, aiming to provide a more engaging learning experience. A printed edition is also planned for those who prefer physical books.
This rework is led by Rodrigo Girão Serrão, with contributions from GitHub community members and feedback from users reporting issues or suggesting improvements. The updated content will include new chapters covering recent features introduced in Dyalog APL 12.0 and beyond.
Why It Matters
This development matters because it addresses the need for current, accessible learning resources for Dyalog APL, a language with niche but growing interest in data analysis and array programming. The integration of interactive tools like Jupyter Notebooks can significantly enhance understanding and experimentation, making it easier for newcomers and experienced users to stay up to date.
