1.2.0

  • Added "open" and "close" fields to single and double quoted strings (#139).

  • Fixed an issue related to closing brackets in raw strings (#162).

  • Binary exponents are now supported in hexadecimal constants (#159).

  • NULL is now allowed as a function call argument name (#164).

  • ... and ..1 are now supported in more places, such as x$... and x@..1 (#148).

  • fn(a b) is now correctly parsed as an error rather than as two sequential arguments (#140).

  • Fixed another issue where the program node didn't start at (0, 0) if there was leading whitespace before the first token (#151).

  • Newlines after function but before the () are again allowed (#145).

  • Newlines are now allowed after an else but before the alternative (#141).

  • parenthesized_expression has been simplified to better align with R's parser. Specifically, it now expects exactly 1 required body expression, rather than allowing zero or more optional expressions (#144).

  • highlights.scm now includes ! as an @operator.

  • tags.scm now tags function definitions with a string name as @definition.function (#147, @MichaelChirico).

  • Removed an unnecessary optional() from _parameter_with_default (#161).

  • The internal _hex_literal rule was simplified slightly (#138).

  • Changed a number of internal files to match tree-sitter v0.24.7 recommendations (#169).

1.1.0

  • Switched to using tree-sitter-language in the Rust bindings to remove a dependency on a specific tree-sitter crate version (#133).

  • Fixed an issue where the program node didn't always start at (0, 0) (#134).

  • To align better with the R grammar and to greatly simplify the possible states in the tree-sitter grammar, some fields are no longer optional (#132).

    • The "body" field of function_definition, for_statement, while_statement, and repeat_statement.
    • The "close" field of braced_expression and parenthesized_expression.

1.0.1

  • Changed tree-sitter dependency from 0.22.6 to >=0.21.0 to match other grammars and be less restrictive.

1.0.0

  • This release incorporates a complete rewrite of the grammar which has been incubating on the next branch for the past two years. It contains many bug fixes and improvements. If you still need to use the previous version, you can pin to the main-old branch, which is the commit just before the next branch was merged in.

  • Added a CHANGELOG.md to track changes.
