• The compile-angel Emacs package: Byte-compile and Native-compile Emacs Lisp libraries Automatically
  by James Cherti
  The compile-angel Emacs package automatically byte-compiles and native-compiles Emacs Lisp libraries. It offers two global minor modes: These modes speed up Emacs by ensuring all libraries are byte-compiled and native-compiled. Byte-compilation reduces the overhead of loading Emacs Lisp code at runtime, while native compilation optimizes performance by generating machine code specific to your system. NOTE: It is … Continue reading →

• Emacs: Automating Table of Contents Update for Markdown Documents (e.g., README.md)
  by James Cherti
  When working with markdown files in Emacs (e.g., README.md), users may need to manually update the table of contents. Automating this process saves time and ensures that the table of contents remains consistent with the document structure. This article presents an Emacs Lisp code snippet that uses: The code snippet that updates the table of contents and … Continue reading →
• Emacs: Maintaining proper indentation in indentation-sensitive programming languages
  by James Cherti
  As codebases grow, maintaining proper indentation becomes increasingly difficult, especially in languages like Python or YAML, where indentation is not just a matter of style but an important part of the syntax. When working with large code blocks or deeply nested structures, it’s easy to lose track of the correct indentation level, leading to errors and decreased … Continue reading →
• dir-config.el – Automatically find and evaluate .dir-config.el Elisp files to configure directory-specific settings
  by James Cherti
  The dir-config.el Emacs package automatically loads and evaluates Elisp code from a .dir-config.el file found in the buffer’s current directory or its closest parent directory. This facilitates adjusting settings or executing functions specific to the directory structure of each buffer. For instance, you can use the dir-config package to: Installation To install the dir-config from MELPA: (use-package … Continue reading →

• outline-indent.el – Indentation based Folding and Outlining in Emacs
  by James Cherti
  The outline-indent.el Emacs package provides a minor mode that enables code folding and outlining based on indentation levels for various indentation-based text files, such as YAML, Python, and other indented text files. In addition to code folding, outline-indent.el allows moving indented sub-trees up and down, promoting and demoting sections to adjust indentation levels, customizing the ellipsis, and … Continue reading →
• How to make cron notify the user about a failed command by redirecting its output to stderr only when it fails (non-zero exit code)
  by James Cherti
  Cron jobs can handle everything from system maintenance to running backups, but monitoring their success or failure can be difficult. One effective way to handle cron job errors is by utilizing a Bash script that sends the output to stderr only if the job fails, which generally makes cron to notify the user about the error that … Continue reading →
