Nobody wants to have to run their own formatter rules in reverse in their head just to know what to grep for. That defeats the point of formatting at all.

That's why you grep for a syntactic structure, not undifferentiated text.

Which grep doesn't do and you need to either use a new different tool or more likely several for little real benefit

grep is half a century old now.

If we can’t progress our ecosystem because we are reliant on one very specific 50+ year old line parser, then that says more about the inflexibility of the industry to move forward than it does about the “new” ideas being presented.

We still use grep because its useful. And it's useful precisely because it doesn't depend on syntax so will work on anything text based.

		grep is great. My point isn’t that we shouldn’t use it. My point is that we shouldn’t be held back by it.

The things all being described are way beyond non trivial to solve, and they'd need to be solved for every language.

Grep works great.

		> The things all being described are way beyond non trivial to solve, and they'd need to be solved for every language. Except it already is a solved problem. If languages compile to a common byte code then you just need one tool. You already see examples of this with things like the IR assembly produced by LLVM, various Microsoft languages that compile to CLR, and the different languages that target JVM. There are also already common ways to create reusable parsing rules like LSP for IDEs and treesitter. In fact there are already grep-like utilities that are based on treesitter. So it’s not only very possible to create language agnostic, reusable, tools; but these tools already exist and being used by a great many developers. The problem raised in the article is that we just don’t push these concepts hard enough these days. Instead relying on outdated concepts of what source code should look like. > Grep works great For LF-separated lists it does. But if it worked great for structured content then we wouldn’t be having this conversation to begin with.

comby is fantastic, give it a shot. It’s saved me huge amounts of time.

You'd need all-news tools for non-text world as well.

So the real choice is either:

- new tool: grep with caching reverse-formatter filter.

- new tool: ast-grep with understanding of AST serialization format for your specific language.

At least in the first case, you still have fall back.
