I've been building an 'extract function' refactor feature. It's surprisingly nuanced. Where do you put the extracted function? Once you've done the static analysis, what order do you use for the parameters?

I had a third attempt at porting difftastic from Dijkstra to A*, and I've eventually concluded that A* just isn't worth it for the implementation complexity. I had fun writing it up though, and I've even attempted ASCII art for building intuitions:

No longer pursuing A* · Wilfred/difftastic@7479636

Closes #1007

Anthropic used Claude to write a C compiler in Rust (CCC). I've really enjoyed following the discussion. The initial post shows how they wrote the harness with GCC as an oracle and a prompt specifying a design using SSA. The author has clear domain expertise. https://www.anthropic.com/engineering/building-c-compiler

Today I learnt that Emacs 28 shipped a context-menu-mode! https://oylenshpeegul.gitlab.io/blog/posts/20230129/ This seems quintessentially Emacs: deeply hackable, but building UI features in an order very different to the mainstream.

Context menus in Emacs 28!

Today I learned that Emacs 28 added context-menu-mode so that we can easily add context menus. This is a minor mode which you can toggle with M-x context-menu-mode RET but I added hooks to enable it for text mode and a couple others (add-hook 'text-mode-hook 'context-menu-mode) (add-hook 'shell-mode-hook 'context-menu-mode) (add-hook 'dired-mode-hook 'context-menu-mode) I did not hook prog mode because some of the fancier lsp things already use mouse-3.
