structured editing

A RacketCon talk presenting Fructure, a prototype extensible structured editing engine in Racket. Language providers define syntactic forms and refactorings as rewrite rules, and editing operates on program structure rather than on text.

Kevlin Henney revisits structured programming, from Go To Statement Considered Harmful to block-structured code and object orientation. He argues it still matters for how we write code today.

Vim author Bram Moolenaar's 2007 Google Tech Talk on habits for efficient text editing: find inefficiencies in your own editing, then learn the Vim commands that fix them.

Vim creator Bram Moolenaar's 2007 Google Tech Talk on habits for efficient text editing. He explains how to spot repetition and inefficiency, then use editor features to fix it.

Pokey Rule presents Cursorless, a spoken language designed for editing code by voice, built on tree-sitter parsing with smart structural and simple token-level primitives. The talk is from Strange Loop 2023.

Shaun Lebron surveys 50 years of Lisp editing history and forgotten innovations in structural editing. He argues future Clojure editors could learn from them, and covers ideas like Parinfer.

Chris Toomey of thoughtbot explains Vim as a language of commands, motions and text objects that combine into precise edits. He shows how to master the built-in pieces and extend them.

Nathaniel J. Smith's PyCon 2018 talk introducing Trio, a Python concurrency library designed around usability and structured concurrency. He live-codes a problem and analyzes pitfalls in other async libraries.

Edwin Brady, creator of Idris, introduces type-driven development in a dependently typed language. He shows types being written first and programs derived with interactive editing, then extends beyond simple examples to programs that interact with users and networks.

Martin Kleppmann's GOTO Berlin 2016 talk on how collaborative editors, offline apps, and multi-datacenter databases handle concurrent updates. It covers conflict resolution approaches including operational transformation and CRDTs, with a worked look at text CRDTs.

Martin Kleppmann's QCon London 2018 talk on keeping data consistent in distributed systems without a central leader. It surveys CRDT algorithms for syncing devices and collaborative editing over peer-to-peer networks.

Kevlin Henney argues that procedural programming never went away despite later paradigms such as OO and functional. He traces the history of structured programming and shows where procedural thinking still lives in modern code and why it matters for readability.

Neil Fraser of Google presents Differential Synchronization, the algorithm behind MobWrite, for keeping multiple copies of a document in sync in real time. The talk argues the approach is robust, convergent and efficient.

TJ DeVries coins the term PDE (Personalized Development Environment) to describe editors like Neovim that you shape to your own workflow. He contrasts this with out-of-the-box IDEs and discusses why customizable tools appeal to developers.

Martin Kleppmann surveys current research on CRDTs, the algorithms for merging concurrent edits across offline replicas. He covers the hard parts such as rich text, moves and merge results that are technically correct but poor.

Photopea founder Ivan Kutskir talks about developing a free browser-based photo editor, one of the most complex JavaScript programs ever written, and the web technologies behind it.

Rich Hickey's long presentation on Clojure and concurrency covers locking and immutability, then goes in depth on refs, transactions and agents. It ends with a multithreaded ant colony simulation demo.

Johann Korndorfer's NVScene 2015 talk on building content with signed distance functions. It focuses on patterns that make SDF modelling more structured, arguing that SDFs capture a shape's essence like vector graphics do compared with polygons or voxels.

Morten Rand-Hendriksen's WordCamp Europe 2017 talk presents CSS Grid Layout as a native two-dimensional layout system that changes how web pages are structured, including responsive layouts independent of source order. It was given as browsers began shipping support.

Paul Irish and Pavel Feldman present the newest Chrome Dev Tools features at Google I/O 2011, including live CSS editing, saving changes, breakpoints and network analysis. It also covers remote debugging.

Salman Khan explains why he created Khan Academy, a structured library of video lessons with interactive exercises. He calls on teachers to flip the classroom, with lectures watched at home and homework done in class with teacher help.

Jason Perkins's talk at Vintage Computer Festival East 2020 compares the user interface of the Xerox Star with that of the Apple Lisa. It covers editing documents, the Star's mouse and a Q&A.

A 2015 GDC talk by Bungie's Barry Genova on how Destiny's engine was restructured into a job graph with limited thread pre-emption. It is aimed at programmers of demanding game engines.
