Why

Ripgrep is a fast search tool like grep. It's mostly a drop-in replacement for ag, also know as the Silver Searcher.

helm-ag is a fantastic package for Emacs that allows you to display search results in a buffer. You can also jump to locations of matches. Despite the name, helm-ag works with ripgrep (rg) as well as with ag.

How

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2025-03-24: Commenting is disabled permanently. Previous comments are archived at web.archive.org. ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

Bash internal field separator (IFS) usage

The IFS internal variable is used to determine what characters Bash defines as word/item boundaries when processing character strings. By default set to whitespace characters of space, tab, and newline.

Running the example ifs.sh, comparing the difference between the default and setting only newline as a boundary we get the following output:

/path/to/first
file
/path/to/second

  * Context menu for mpv using Tcl/Tk. Mostly proof of concept.
  * Avi Halachmi (:avih) https://github.com/avih
  *
  * Features:
  * - Simple construction: ["<some text>", "<mpv-command>"] is a complete menu item.
  * - Possibly dynamic menu items and commands, disabled items, separators.
  * - Possibly keeping the menu open after clicking an item (via re-launch).
  * - Hacky pseudo sub menus. Really, this is an ugly hack.
  * - Reasonably well behaved/integrated considering it's an external application.
