3. Searching and Editing Text

Published

Thursday, September 12, 2024

This week …

Most of our work is not done interactively. We write things down as “code” in its broadest sense: just sequences of instructions and commentary on them. We need a good set of tools for editing and manipulating all the text we produce. So this week we will cover

The idea of text search and manipulation via regular expressions
Text Editors

Required Reading

Jeffrey E F Friedl Mastering Regular Expressions, 3rd ed. (Sebastopol, CA: O’Reilly Media, 2006)., Chapter One

Background Material

The books on Vim and Emacs are only of interest if you plan on learning one or other of those editors, which I don’t necessarily recommend at this point. We’ll talk more in class about how you should think pragmatically about your choice of text editor.

Arnold Robbins and Nelson H. F. Beebe Classic Shell Scripting (Sebastopol: O’Reilly, 2005).
Drew Neil Practical Vim, 2nd ed. (Raleigh, NC: Pragmatic Programmers, 2015).
