Escape codes, enter comment chaos
There's no escaping it: an exploration of ANSI codes
A 50-year-old text trick is still everywhere, but commenters wanted less fluff and more facts
TLDR: The article explains how an almost 50-year-old text-based standard still powers colors, movement, and simple animations in command windows today. Commenters weren’t wowed by the write-up, though, with several saying it needed fewer flourishes, more substance, and one even pointing readers to Wikipedia for a better explainer.
A love letter to one of computing’s oldest magic tricks has landed online, and the real fireworks happened in the comments. The article explores the hidden text commands that make terminal windows do flashy things like show colored words, move the cursor around, and update progress bars in place. In plain English: a lot of the “fancy” stuff you see in old-school command windows still runs on a standard cooked up in the late 1970s, and somehow it’s still pulling its weight today.
But while the post aimed for wonder and history, the comment section came in with a sharp "cool story, where’s the substance?" energy. One reader flatly said they were expecting something “more informative,” while another took the knife a little deeper, arguing the piece would be better with “just the widget” and a tiny bit of explanation instead of extra padding. Ouch. That set the mood fast: less applause, more editorial side-eye.
Then came the classic internet power move: the Wikipedia reply guy. One commenter dropped a Wikipedia link and casually suggested it goes “a bit more in-depth,” which is basically comment-section code for thanks, I’ll read the better version instead. No meme avalanche this time, but the dry snark absolutely delivered. The big takeaway? Readers agree the underlying idea is genuinely impressive — a nearly 50-year-old system still powers modern text interfaces — but they were split on whether the article explained that magic well enough, or just dressed it up in nostalgic sparkle.
Key Points
- •The article explains that ANSI escape codes were standardized in 1979 to add control behavior such as formatting and cursor movement to plain-text terminal streams.
- •ANSI escape sequences begin with the ESC character (`\x1b`) and `[` to form the Control Sequence Introducer, followed by command parameters and a final command letter.
- •Examples in the article include codes for red text, bold text, reset formatting, clearing the screen, and moving the cursor.
- •The original specification supported 8 colors, while modern terminals expanded support to 256-color and 24-bit color modes.
- •The article says ANSI codes still power modern CLI output and are used by libraries and terminal applications such as Spectre.Console, chalk, Vim, and htop.
