Sourcetrail VS difftastic

I wish something existed in this space. I used Coati Software's Sourcetrail for a couple of years. Unfortunately it was discontinued. It was a wonderful piece of software that indexed a code repository, and exposed an interface to explore it interactively. At least for me, it significantly improved the understanding and legibility of code.

The code is in an archived state (https://github.com/CoatiSoftware/Sourcetrail). Searching for the software on Google shows some screenshots.

I think it might make large scale code visualization in a similar way to how SourceTrail does it more feasible: https://github.com/CoatiSoftware/Sourcetrail

I've used https://github.com/CoatiSoftware/Sourcetrail in the past for some bits of the legacy code project I'm on. I also use vim and cscope for day to day navigation but it's harder to get a big picture with those alone.

Sourcetrail?

Does it strive to do what Sourcetrail used to ?

You could always try using Sourcetrail. Unfortunately the open source project is now archived but it should still help you get insights into your 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.

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 It supports more languages, but doesn't recognize when code has been replaced by an equivalent version ("invariances").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