There was a problem hiding this comment.
Maybe it would be better to print errors to stderr:
Suggested change
| echo "Error: lsqlite3 module is not installed" | |
| echo "Install it with: luarocks install lsqlite3" | |
| echo "Error: lsqlite3 module is not installed" >&2 | |
| echo "Help: luarocks install lsqlite3" >&2 |

Great contribution, I hope it gets reviewed ❤️ Would a small unit test be possible? |

/examples/simple-lua/ contains a demo script and runner. Incorporates upstream PR asg017#237 with the following bugfixes: Extension loading: - Fix return value check: lsqlite3's load_extension returns true on success, not sqlite3.OK (which is 0). Changed from `if ok then` to `if ok and result then` to properly detect successful loads. - Add vec0 naming paths alongside sqlite-vec paths for this fork. IEEE 754 float serialization (float_to_bytes): - Switch from half-round-up to round-half-to-even (banker's rounding) for IEEE 754 compliance. This prevents systematic bias when processing large datasets where half-values accumulate. - Handle special cases: NaN, Inf, -Inf, and -0.0 which the original implementation did not support. - Fix subnormal number encoding: corrected formula from 2^(exp+126) to 2^(exp+127) so minimum subnormal 2^(-149) encodes correctly. - Add mantissa overflow carry: when rounding causes mantissa >= 2^23, carry into exponent field. - Add exponent overflow handling: values too large now return ±Inf instead of producing corrupted output. - Use epsilon comparison (1e-9) for 0.5 tie detection to handle floating-point precision issues. JSON serialization (serialize_json): - Error on NaN and Infinity values which are not valid JSON. - Convert -0.0 to 0.0 for JSON compatibility.

@karminski I've made a tweak to your PR and incorporated it into version v0.2.4-alpha of my fork. |
