• Installing Arch Linux onto a separate partition from an existing Debian-based distribution (Ubuntu, Debian, Linux Mint…), without using the Arch Linux installation media
  by James Cherti
  Installing Arch Linux typically begins with booting from official installation media. However, it is also possible to bootstrap an Arch Linux installation from within a running Debian-based system (Ubuntu, Debian, Linux Mint, etc.). This method is advantageous in environments where rebooting into live media is impractical or when remote installation is desired. This article outlines a workflow … Continue reading →

  by James Cherti
  The minimal-vim-config project is a Vim configuration that is intended to serve as a solid foundation for a Vim configuration. The author began developing this configuration upon first adopting Vim and has continuously refined it over 25 years of research and testing to identify the most effective parameters and optimizations for a Vim configuration file. This Vim … Continue reading →
• Enhancing Git Diff for Emacs Lisp: Better Git Diff of Elisp function or macro definitions
  by James Cherti
  By default, the git diff algorithm compares changes in Elisp files line by line without understanding the structural semantics of Emacs Lisp files. This means that when modifications are made within functions, the diff output does not convey how those changes relate to higher-level code constructs such as functions or macros. As a result, reviewers are presented … Continue reading →
• Python: How to Clear Stdin Before Using the input() Function
  by James Cherti
  In Python, the input() function is commonly used to capture input from the user. However, issues may arise when unwanted or unexpected data is present in the stdin, leading to incorrect or incomplete results when calling input(). A reliable approach to address this issue is to clear the stdin buffer before invoking input(). This article discusses why … Continue reading →

  by James Cherti
  Imagine you’re working in a tmux session, navigating logs, editing config files, or running commands, and you suddenly need to reuse a path, a variable name, or a keyword that appeared earlier on the tmux scrollback buffer. Instead of scrolling back or retyping it manually, you press Ctrl-n, type a few fuzzy letters, press enter, and the … Continue reading →

• Git: Suppressing Irrelevant Git Diff Output for Specific Files (e.g., binary files, encrypted files…)
  by James Cherti
  Sometimes, it is useful to suppress certain files from git diff output, especially when the files are large, machine-generated, or not intended for human reading. Typical examples include encrypted files such as *.gpg and *.asc, as well as binary assets like images, audio files, and similar media. These files are usually represented as opaque binary data in … Continue reading →
• Emacs: stripspace.el – Automatically Remove Trailing Whitespace Before Saving a Buffer, with an Option to Preserve the Cursor Column

  The stripspace Emacs package provides stripspace-local-mode, which automatically removes trailing whitespace and blank lines at the end of the buffer when saving. (Trailing whitespace refers to any spaces or tabs that appear at the end of a line, beyond the last non-whitespace character. These characters serve no purpose in the content of the file and can cause … Continue reading →
