Years with an HN recommendation, 2007–2026

Commenters cite it as an early example of projectional or intent-based programming tools when discussing alternatives to text-based code.

A roughly ten-minute demo of Microsoft's Intentional Programming research system, showing its editor and an unusual way of working with code. It is the first of two clips cut from a longer video.

“Here are a couple of demo vids from well over 10 years ago” (HN, 2016)

There are some interesting ideas that could help with reading and writing programs: from Bret Victor: [link] and intentional programming from Charles Simonyi: [link] [this video]

on HN thread I'm looking for a partner or two (here are some of my ideas, feel free to add your own here)
I am interested in seeing what happens when you apply intentional programming to web [this video] idea is to open up your search engine so that anyone can submit code for domain specific query entry, search, ranking, and presentation of results. Moreover, such code submissions would compete with each other, with more effective ones rising in popularity in their respective domains. Unlike APIs that are currently available, the submissions made by users here would make up the core feature set of the service.

I wonder if it would make sense to make a search engine platform where (more technical) users can submit code for domain specific query entry, search, ranking, and presentation of results. Moreover, such code submissions would compete with each other, with more effective ones rising in popularity in their respective domains. Unlike APIs that are currently available, the submissions made by users here would make up the core feature set of the service. This is sort of like intentional programming, but applied to [this video]

on HN thread Ask HN: Is the architecture of programming tools historical accident?
It's a shame the Intentional Software crew have been nearly silent for the a decade or so they've been in business. They've been doing projections-of-ASTs based programming for a very long time. They bragged a lot about it early on and I haven't heard much of anything since. Here are a couple of demo vids from well over 10 years ago: [this video] [link] Here's an interview from 2009 where one of the crew members talks about an annotated S-expression as the core code representation (IIRC, it's been a long time since I listened to it) [link]

Charles Simonyi's Intentional Software was doing that back in the days of Windows NT [this video] But, they stayed insular and enterprise right up until Microsoft bought them back. We mortals barely got to see or hear anything about it. I heard one podcast interview of a developer there who said they basically represent the code as an s-expression tree with a bunch of metadata on each node.

on HN thread Clean your codebase with basic information theory
Intentional Software was working on a system like this many years ago: [this video] Part 2: [link] You can project your programs into different views and add lots of metadata about the program and use that data in various contexts. Also extends to source control and other use cases. It looked really neat. I'm not sure what happened to it.
