TextSnatcher VS difftastic

- https://github.com/RajSolai/TextSnatcher

Thanks to Gtk4 support and packages available on macOS via homebrew. Today I was successful able to build .app for the app. You can track the progress here https://github.com/RajSolai/TextSnatcher branch 'macos-dev'

You can do this from a desktop app like https://github.com/RajSolai/TextSnatcher

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.

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".

Yes there is an `—-override` option you can use to specify the language in which a file should be parsed.

Use the fantastic difftastic instead of git's diff. https://difftastic.wilfred.me.uk/

difftastic provides similar capabilities in a free tool based on treesitter

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 It supports more languages, but doesn't recognize when code has been replaced by an equivalent version ("invariances").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.

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.

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.
