In plain words
HTerm is a graphical terminal application for macOS, Linux, and iOS that displays inline images and graphics without requiring server-side support or additional dependencies beyond base64 encoding. It leverages the ReGIS graphics language, originally used in 1980s terminals, to render simple graphics directly within the terminal interface. The tool is designed for developers who want to incorporate visual elements into command-line workflows across multiple platforms.

A graphical terminal requiring no serverside support. Available for MacOS X, Linux and iOS. Display inline image data, without opening a backchannel, the only dependency is base64! It's not well known, but graphical terminals have been around for more than 25 years. One of the earliest implementations was in the VK100 (or “GIGI”) terminal, released in the early 1980s, it used a graphics drawing langauge called ReGIS . Lucky Gnuplot still supports ReGIS, and we can use this capability to render simple graphics simply and quickly in the terminal. See the examples sections for a quick walkthrough.

Talanoa▲345Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
