TypeQL 3.10.4

TypeQL Grammar and Language Library distributions for Rust

Available through https://crates.io/crates/typeql.

cargo add typeql@3.10.4

New Features

Bugs Fixed

Code Refactors

Other Improvements

• Allow leading comma in redefine constraints

  Mirrors the leading-comma sugar already accepted by define: define person, owns name; parses, but redefine person, owns name @card(0..10); did not. Make redefinable_type accept an optional COMMA between the label and the constraint so concat-based query generation has the same shape for define and redefine.

• Update Rust dependencies

TypeQL 3.10.1

TypeQL Grammar and Language Library distributions for Rust

Available through https://crates.io/crates/typeql.

cargo add typeql@3.10.1

• Update dependencies

• Update Rust to 1.93.0

TypeQL 3.10.0

TypeQL Grammar and Language Library distributions for Rust

Available through https://crates.io/crates/typeql.

cargo add typeql@3.10.0

New Features

• Implement unicode unescaping
  Escaped unicode characters can be used in TypeQL string literals. These must be of the form \uXXXX (exactly 4 hex digits), or \u{XX...X} (1 to 6 hex digits).

Bugs Fixed

Code Refactors

Other Improvements

• Fix parser for inserting with anonymous relation syntax
  Fixes a bug in parsing for inserting with anonymous relation syntax

• Minor grammar refactor for parser performance improvements
  Reordering the choices to boost performance by failing faster and having more frequent alternatives earlier. Also removes the !reserved check for identifiers and expects this to be handled in an application post-check.

• Bazel 8 upgrade

  Update Bazel version from 6.2 to 8.5.1.

  The upgrade is done in a backwards-compatible way, such that "upstream" repositories that are yet to be upgraded may depend on this repository. This is done by preserving WORKSPACE and the deps.bzl loader files alongside the new Bazel 8 ones. Once every repository has been upgraded to Bazel 8, these files will be removed.

TypeQL 3.8.3-rc0

TypeQL Grammar and Language Library distributions for Rust

Available through https://crates.io/crates/typeql.

cargo add typeql@3.8.2

New Features

• Allow leading underscore in type labels

  We relax our identifier rules, allowing _ as a leading underscore in type labels. This does NOT extend to variables, since we have some complexity around anonymous variables for the time being we don't want to modify.

Bugs Fixed

Code Refactors

• Introduce Collector variant of Reducer to accomodate the unimplemented list reducer
  It was placed under Stat, which it is not and caused confusion & crashes in core.

Other Improvements

• Add tests for end; clause in query pipelines

  Add tests for end; statements

• Allow decimal syntax without a period

  To give both humans and LLMs more flexibility when writing decimal value types, we no longer requiring the .0 in xxx.0dec. This is unambiguous since the dec suffix already syntactically differentiates when a value is a decimal.

TypeQL 3.8.0

TypeQL Grammar and Language Library distributions for Rust

Available through https://crates.io/crates/typeql.

cargo add typeql@3.8.0

New Features

• Add built-in functions iid() and label()

  We add iid() and label() to the built-in functions in the TypeQL grammar.

Bugs Fixed

• Use XID_START and XID_CONTINUE character classes

  We use XID_START and XID_CONTINUE character classes provided by pest instead of manually listing unicode codepoint ranges for our identifiers. We also change the definition of the word boundary (WB) to be "any character that is not an identifier continuation character" that resolves parsing bugs such as let $var= 4; failing to parse: = is not PUNCTUATION, so not valid word boundary.

Code Refactors

Other Improvements

• Expose value parser

  We expose value parsing as a top-level function, and update the value literal definitions. This lets us re-use the value parser for test frameworks in other repositories.

• Update TypeQL banner image link in README

• Add contributing guidelines to CONTRIBUTING.md

• Allow trailing commas (#421)

  To simplify writing and generating queries, we allow trailing commas anywhere we use a comma separated list of variables, statements, reductions, etc.

• Remove discussion and Stack Overflow links

TypeQL 3.7.0

TypeQL Grammar and Language Library distributions for Rust

Available through https://crates.io/crates/typeql.

cargo add typeql@3.7.0

New Features

• Try blocks in write stages

  We allow try {} blocks in all write stages, viz. insert, delete, put, and update.

Bugs Fixed

Code Refactors

Other Improvements

• Change CODEOWNERS

• Fix illegal grammar error formatting

  We fix the (internal) illegal grammar error formatting to show the part of the query that caused the error rather than the corresponding parsed subtree.
