I finished all the exercises in `Elisp Intro’ while reading it, only a few of them were a little tricky, while others were quite simple. I’ve organized my solutions and uploaded them to Github for your reference (suggestions/bugs fixes are welcome <renws1990@gmail.com>):

Because Elisp Intro is written for people who are not programmers, its content is a little bit shallow. But overall, it covers quite a few valuable topics:

• Lisp basics
• Buffer related functions
• Recursion
• Regular expressions
• Narrowing and widening
• kill-ring
• The implementation of List
• TAGS
• Debugging
• Initialization

For Emacs users like me who do not read manuals often, going through this book will at least complement your skill-set with Emacs. Among these topics, `kill-ring’ and `regular expressions’ especially helped me on improving my editing efficiency.

For Emacs users who do not want to learn Elisp, read “Chapter 16: Your `.emacs’ File” might help you on configuring Emacs.

In addition, “Chapter 11.3 Recursion” will be handy for beginner programmers who want to learn recursion.

• In my opinion, `Elisp Intro’ is too basic. Some useful features such as function advising is not covered. You won’t gain enough skills to write an Emacs extension after reading it.
• The author likes to use complicated (to me) English grammars that did confuse me sometimes.
