PRQL compiler CLI - prqlc 0.13.12 ڈاؤن لوڈ

0.13.12 has 81 commits from 10 contributors. Selected changes:
Language:
- Remove the deprecated std.prql_version function. Use prql.version instead, which has been the supported replacement since 0.11.1. (@prql-bot, #5806)
Features:
- Add a very early sql.oracle dialect. It currently only forces identifier quoting to accommodate Oracle's case-folding rules; most other features fall back to generic SQL. (@julien-pinchelimouroux, #5821)
- Add date.trunc function for date truncation. (@happyso, #5729)
- Add date.now function for current timestamp. (@happyso, #5721)
- Add date.diff function for date differences. (@happyso, #5726)
- Add DuckDB target to the Elixir bindings. (@prql-bot, #5817)
Fixes:
- Loosen the chrono constraint from 0.4.44 to 0.4 to avoid version conflicts with downstream crates such as polars. (@lukapeschke, #5834)
- Correct the SQLite div_i formula so integer division returns the right result when |dividend| < |divisor| (e.g., 1 // 2 now returns 0 instead of -1). (@queelius, #5736)
- Return an error rather than emitting invalid SQL when date.trunc is used against SQLite. (@prql-bot, #5733)
- Sync :duckdb into the Elixir PRQL.Native.CompileOptions target typespec so target: :duckdb actually reaches the DuckDB dialect. (@prql-bot, #5823)
- Correct the Vec::from_raw_parts element type in prqlc-c to fix undefined behavior in result_destroy. (@prql-bot, #5732)
- Prevent panic in prqlc-macros by correcting a stale macro name in the panic message. (@prql-bot, #5811)
- Align Emacs grammar keywords and regex with the lexer. (@prql-bot, #5795)
- Correct the playground's decimal regex and transforms list in syntax highlighting. (@prql-bot, #5788)
- Correct the aarch64 target path in the Java cross-compilation script. (@prql-bot, #5781)
Documentation:
- Numerous typo, grammar, and stale-content fixes across the book, tutorials, bindings docs, and code comments.
Integrations:
- Kakoune 2026.04.12 has syntax highlighting for PRQL. (@vanillajonathan)
Internal changes:
- Add tend (Claude-powered CI) workflows for autonomous PR review, issue triage, CI-failure fixes, and a nightly code-quality sweep. Most of this release's bot-authored fixes were filed by tend. (#5727)
- Update the Rust toolchain version. (#5807)
- Switch from mypy to ty for Python type checking. (#5761)
