First, note the method prefix_allowed_tokens_fn. This method applies a Pydantic model to constrain/guide how the LLM generates tokens. Next, see how that constrain can be applied to txtai's LLM pipeline.
Project mention: The Future of MySQL is PostgreSQL: an extension for the MySQL wire protocol | news.ycombinator.com | 2024-04-26This is probably referring to "zero changes to your driver code" and not "zero changes to the SQL you send over this driver".
Translating between SQL dialects is notoriously hard and attempts to translate [1] are working in 95% of cases. But the last 5% would require 5x amount of work. That's because "SQL dialect" also includes weird edge cases of type inference of things like COALESCE(5, FALSE) and emulation of system catalogs (pg_catalog, information_schema).

I love to use PDFMiner and PDFQuery for this https://github.com/pdfminer/pdfminer.six https://towardsdatascience.com/scrape-data-from-pdf-files-using-python-and-pdfquery-d033721c3b28
Project mention: Show HN: I wrote a RDBMS (SQLite clone) from scratch in pure Python | news.ycombinator.com | 2023-08-13Lark supports, and recommends, writing and storing the grammar in a .lark file. We have syntax highlighting support in all major IDEs, and even in github itself. For example, here is Lark's built-in grammar for Python: https://github.com/lark-parser/lark/blob/master/lark/grammar...
You can also test grammars "live" in our online IDE: https://www.lark-parser.org/ide/
The rationale is that it's more terse and has less visual clutter than a DSL over Python, which makes it easier to read and write.
