Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Any else using Meta's née Facebook's Watchman service?
Facebook Meta's Watchman Service looks very useful for watching for changes in files and directories to kick off automation. Still, there seem to be a bunch of gotchas with it that only come to light after trying to mess with it. The docs seem lacking, the Python library needs to be updated, and even the installation on non-Ubuntu or Red Hat distros requires a rebuild, which has been somewhat problematic given the build tools. Also, no official Docker container.

Watchman: Execute a command when something changes
Not to be confused with Facebook’s file watch daemon, which does the same sort of thing but is more complicated. There’s a bunch of tools that integrate Facebook’s watchman for more efficient change tracking.

Linus Torvalds adds arbitrary tabs to kernel code
i want a diff tool that shows me exactly which tokens have changed, and which haven't, regardless of how they are laid out.
These already exist: https://github.com/Wilfred/difftastic
when we get that, then we should get even less merge conflicts.
Counterintuitively, that is not the case. AST-merge is a much, much, much, much, much harder problem than AST-diff.
https://github.com/Wilfred/difftastic?tab=readme-ov-file#can...
The fact that diffs can be used to drive a 3-way merge is in fact an accidental property that arises due to the sheer crudeness of the diff format. As soon as you start using more-sophisticated diff formats, solutions to "the diff problem" no longer lead directly to solutions to "the merge problem".

Difftastic, a structural diff tool that understands syntax
Yes there is an `—-override` option you can use to specify the language in which a file should be parsed.

Prettier $20k Bounty was Claimed
If you're looking for a VS Code extension or a GitHub app, check out https://semanticdiff.com/. I'm a co-founder of this project.
If you prefer a CLI tool, check out https://github.com/Wilfred/difftastic. It supports more languages, but doesn't recognize when code has been replaced by an equivalent version ("invariances"). So it will show some changes (e.g. replacing a character in a string with an escape sequence) even though they are technically equivalent.

Pijul: Version-Control Post-Git • Goto 2023
Shameless plug: I've written difftastic[1], a tool that builds ASTs and then does a structural diff of them. You can use it with git too.
It's an incredibly hard problem though, both from a computational complexity point of view, and trying to build a comprehensible UI once you've done the structural AST diff.

Always leave a trailing comma in Python lists, dicts, tuples
There is a diff tool called difftastic: https://github.com/Wilfred/difftastic
The idea is that it does not show diff based on text change, but on syntastic meaning. For that, it uses tree-sitter.
I think it still shows the trailing comma in the situation as shown in the article, but it's quite different experience than the standard text based diff.
What are some alternatives?
