Tool author here. I think the same overall approach I described here should work for Go as well: https://news.ycombinator.com/item?id=36653954 One would just need a machine readable data source for Go package APIs, and woul

No worries! Trustfall is even more general than semver actually, one can use it to query any data source -- even HN itself: https://play.predr.ag/hackernews Here's a link to that project if you'd like to check it

cargo-semver-checks is the tooling you describe. It doesn't currently catch every possible semver violation, so it won't suggest version numbers for you yet , but that's the eventual goal!

Tool author here. Your hunch is absolutely right. An analysis I and a few contributors did for Rust showed that over 1 in 6 of the top 1000 most downloaded Rust crates has broken semver at least once in a way our tool can detect & where

cargo-semver-checks author here, thanks for the kind words :) I've written several blog posts about how semver in Rust is particularly tricky and has unexpected edge cases, if you'd like to see specific examples of things non-obvi

Author here! Excited to see this on the front page, ping me with any questions! I recently gave a talk about the tool, addressing: - why semver in Rust is important and harder than it looks - how the tool works - why it took until 2022-2023

I've had my eye on Taxi for a while, and it's neat! I agree that the problems it aims to solve are real and painful in real life. In my experience, I'm not sure people care about schemas or schema languages — they are just im

It's a very exciting time to be working in this space! Going beyond structured databases and file formats like JSON/CSV, there are also systems that can query APIs, source code, ML models, etc. My own Trustfall query engine is one

I'm not sure about arbitrary graphs, because all kinds of weird and wonderful math exists out there :) But from 7 years of working on graph databases, and even participating in some graph query language standardization work, I know two

Thanks! Reactive/live/materialized queries are certainly a possibility I've tried to keep open and I'd love to build, but there's so many possible things to build from here that I'm not sure when that might hap

SQL is kind of a monster language to parse properly[1], and has some unfortunate and confusing edge cases[2]. It would have cost a ton of time and energy to implement properly, and all it would have ended up with is "SQL but worse.&quo

I appreciate it! Writing is hard (especially not in my native language) and I'm always looking to improve, so feedback like this is valuable. To be honest, that blog post was targeted at cargo-semver-checks users and r/rust reader

Good call, thank you! I'll almost certainly do something along those lines.

Might I direct you to a 10min talk I gave on the subject? https://www.hytradboi.com/2022/how-to-query-almost-everythin... The motivation is that queries that are trivial in a SQL database are painfully impractical over

As I wrote in reply to your other comment, the join algorithms are the adapter's choice. I wouldn't necessarily recommend using it as a SQL replacement, though. There's no measurable MoM growth yet. This is the first major lo

Trustfall's Adapter API that data providers implement leaves the joining to the adapter implementation. It provides an iterator of rows and an edge (essentially a join predicate), and asks for an iterator of (row, iterator of rows to w

Trustfall isn't trying to compete with SQL; doing so would be suicidal and pointless. If the dataset being queried already has a statistics-gathering query optimizer, it's just the wrong call to not use that optimizer. If one wrot

The language is syntactically similar to GraphQL, but the semantics are much richer -- in terms of expressiveness Trustfall is more like SQL than GraphQL. No language syntax makes everyone happy :) But it's definitely is something that

To be completely honest, I was planning on doing a "Show HN" in a month or two, but someone posted the link today and it caught me a bit off-guard -- that's why the docs and examples aren't there yet :) There's defi

Yes, in at least two ways: - It could be used as the "ingestion process" itself: write the ingestion as a Trustfall query (or queries) over the data sources, and store the results in a traditional database or other system. - It co

It should all be doable: - Trustfall queries can in principle be compiled into SQL and executed on an analytical database. I haven't built this into Trustfall right now, but a prior project I built that used very similar syntax had thi
