The Rust reference describes `?Sized` as "questionably sized". I feel vaguely judged :)

tree-sitter is adding a notion of reserved keywords, as it previously treated keywords as contextual: https://github.com/tree-sitter/tree-sitter/pull/1635
Includes a fun example of using `if` as a name in JS!
One really nice aspect of fzf completion for ctrl-r is the ability to view multiple candidates at once. It's easier to only show one option to the user, but it's less useful.
(VS Code's Command Palette and modern Emacs minibuffer packages also have this advantage.)
The best interface is no interface: https://web.archive.org/web/20120831083217/http://www.cooper.com/journal/2012/08/the-best-interface-is-no-interface.html/
The author's critique of needing to find an app to accomplish a task is just as relevant today.
I'm writing some docs in markdown, and I'm really glad I can use arbitrary HTML when I need to. It's so handy when you hit the limits of markdown (e.g. tables, named anchors, custom styling).
It's dangerous when you have untrusted input, but I'm beginning to appreciate it.
I'm really impressed with fzf, the terminal fuzzy finder. It makes ctrl-r way more powerful, and it even has a ctrl-t to pass file arguments!
It uses existing terminal history rather than 'enable and now you will have history', which is nice too.

Today I learnt that GitHub Release download counts are publicly available! This is a really helpful way of seeing what proportion of users are on each platform.
The next version of difftastic will support Kotlin too!
I'm fascinated to learn that some distros are including the whole HTML manual in the package!
It seems like a nice thing for users, but I was initially surprised to see JS in the package.

I've been experimenting with supporting the unified diff format in difftastic. This is a single column format ('inline') with @@ markers.
What do you think? This format doesn't scale well to larger changes, but it's super familiar and works with other tools.
Difftastic is the first time I've ever shipped a binary on Windows. It was surprisingly straightforward.
Rust has good Windows support, and GitHub Actions means I don't need to set up a Windows toolchain locally.
Interested in trying difftastic, but don't want to compile it yourself? I now have GitHub releases with prebuilt binaries for Linux, macOS and Windows for you to play with!

Showing lines of context is a remarkably hard problem for a syntactic diff.
Line 23 on the right is new, but lines 24 and 25 also map to the same line on the left! Initially I thought this was a bug.
It's impossible to show exactly N context lines whilst preserving alignment.
Difftastic 0.26 is out!
* Added Gleam, YAML and Zig, improved Clojure
* Language detection can now be overridden
* Better display, better highlighting, and some better diff heuristics :)
Got a bug report on difftastic saying it crashes with an error: "should be impossible: expected XYZ".
I am very glad I phrased my assertion as *should*!
I'm hesitant to write "written in $LANG" on my project READMEs. I'd rather get users excited about the features than the implementation.
Maybe it makes sense if you're primarily seeking contributors?
Bash's list of behaviours that aren't POSIX-compliant is longer than I expected: https://www.gnu.org/software/bash/manual/html_node/Bash-POSIX-Mode.html
I used fish for a while and liked it, but POSIX-ish shells work with everything. These days I use a heavily customised zsh.
Today in tricky diff scenarios: when do you want the inner delimiter to match, and when do you want the outer delimiter to match?
In these examples, lisp looks better with the outer paren matched, whereas rust looks better with the inner brace.
The next version of difftastic will include YAML support, thanks to a pull request by @alexmanno_dev!
It's a nice feature, and difftastic itself even includes some YAML files. Note also the highlighting: you can distinguish strings from boolean literals here.

If over-the-air update systems aren't receiving regular patches, maybe it would be better for industry to use hardware that can't be reflashed remotely?
