21-25: Consider using a more specific type for thelanguageproperty.The
Languagetype is correctly defined. However, thelanguageproperty is of typeunknown, which means it can be of any type. This can lead to potential type safety issues.Consider using a more specific type for the
languageproperty based on the expected value. If the type is not known, consider usinganyinstead ofunknown.

1-27: LGTM!The Python binding code for the Tree-sitter Java grammar looks good:
- It correctly includes the necessary Python headers.
- The
tree_sitter_javafunction is declared to return the Tree-sitter language for Java.- The
_binding_languagefunction correctly returns the pointer to the Tree-sitter Java language as a Pythonlongobject.- The
methodsarray andmodulestruct are correctly defined to create the_bindingPython module with thelanguagemethod.- The

1-54: LGTM!The new
alloc.hheader file is well-structured and follows best practices. The use of macros to allow clients to override allocation functions provides flexibility. The code is clear, concise, and easy to understand.Some key observations:
- The file uses header guards to prevent multiple inclusions.
- The
extern "C"block ensures C++ compatibility.- If the
TREE_SITTER_REUSE_ALLOCATORmacro is defined, it uses client-provided allocation functions.- If the macro is not defined, it defaults to standard C allocation functions.
Overall, the code looks good and is ready to be merged.
resources/language-metavariables/tree-sitter-java/package.json (7)
6-6: LGTM!The addition of the
"types"field improves the developer experience by providing TypeScript type definitions for the package.
11-18: LGTM!The addition of the
"files"field helps reduce the package size by specifying which files and directories should be included in the published package. The listed files and directories appear to be relevant and necessary for the package's functionality.
26-28: LGTM!The update to the
"dependencies"section, replacing"nan"with"node-addon-api"and"node-gyp-build", is a positive change. It suggests a shift towards using more modern and efficient tools for building native Node.js addons, which is likely to improve the package's compatibility and performance.
29-31: LGTM!The addition of the
"peerDependencies"section, specifying"tree-sitter"as a peer dependency with version"^0.21.0", is a good practice. It ensures that the package is used with a compatible version of the"tree-sitter"library, helping prevent potential version conflicts and ensuring the package works as expected.
32-35: LGTM!The addition of the
"peerDependenciesMeta"section, marking the"tree_sitter"peer dependency as optional, provides flexibility for users who may not need the full functionality provided by the"tree-sitter"library. This change allows the package to be used in a wider range of scenarios while still recommending the use of"tree-sitter"for full functionality.
38-39: LGTM!The update to the
"devDependencies"section, replacing"tree-sitter-cli"with"prebuildify", suggests an improvement in the package's build process. The addition of"prebuildify"indicates that prebuilt binaries will be created for the package, which can enhance the installation experience for users by reducing the need to compile the package from source on their machines.
45-47: LGTM!The expansion of the
"scripts"section with new commands"build-test","install", and"prebuildify"is a positive change. These additions enhance the build process and provide more flexibility for developers working with the package. The"build-test"script offers a convenient way to ensure the package builds successfully and passes tests, while the"install"script simplifies the installation process. The"prebuildify"script, likely used with the"prebuildify"development dependency, facilitates the creation of prebuilt binaries for the package.resources/language-metavariables/tree-sitter-java/setup.py (1)
1-60: LGTM!The Python setup script follows the standard structure and conventions. The custom build and bdist_wheel commands are implemented correctly. The package configuration options in the setup function are appropriate for the Tree-sitter grammar package. The C extension module is configured with the necessary source files, compile arguments, and other options. There are no apparent issues or inconsistencies in the code.

65-65: LGTM!The addition of the
("import ", ";")tuple to thesnippet_context_stringsmethod is a valuable change that aligns with the PR objective of improving Java metavariable support for import statements. This tuple correctly represents the context for Java import statements, enabling the parser to handle them appropriately when generating code snippets.resources/language-metavariables/tree-sitter-java/src/tree_sitter/parser.h (5)
17-17: LGTM!The reintroduction of the
TSStateIdtypedef is necessary for the correct functioning of the parser and ensures that the type is consistently defined for state identification.
89-92: LGTM!The introduction of the
TSCharacterRangestruct is a useful addition to the parser implementation. It enhances the ability to manage character ranges effectively within the parsing logic by providingstartandendfields.
133-149: LGTM!The introduction of the
set_containsinline function is a valuable addition to the parser implementation. It optimizes performance when dealing with multiple character ranges by employing a binary search approach to efficiently check for containment. This change improves the efficiency of the parsing logic.
155-159: LGTM!The addition of preprocessor directives to define the
UNUSEDmacro differently for MSVC and other compilers improves the portability of the code. TheUNUSEDmacro is used to suppress warnings for unused variables, and the preprocessor directives ensure that the macro is defined correctly for different compilers.
180-190: LGTM!The modifications to the
SMALL_STATEandREDUCEmacros improve the clarity and maintainability of the code.The
SMALL_STATEmacro is modified to ensure proper parentheses around the subtraction operation, preventing potential issues with operator precedence.The
REDUCEmacro is revised to include additional parameters for dynamic precedence and production ID, enhancing its functionality and flexibility in parsing actions.These changes contribute to the overall robustness and readability of the parser implementation.

resources/language-metavariables/tree-sitter-java/src/tree_sitter/array.h (1)
1-290: LGTM!The generic array implementation in this header file is well-designed and follows best practices. The code is clean, well-documented, and provides a nice set of macros for easy usage. The static inline functions are efficient and handle memory management safely. The binary search implementation is based on a good reference from Rust's standard library. The code is also portable across different compilers and platforms.
Some key highlights:
- Consistent naming convention for macros, functions, and variables.
- Clean separation of public macros and private functions.
- Efficient implementation of array operations using static inline functions.
- Proper use of assertions and memory management functions for safety.
- Portable code with conditional compilation and pragma directives.
Overall, this is a high-quality code for a generic array implementation in C. Great job!

184-184: LGTM!The change to the regular expression pattern in the
escape_sequencerule improves the flexibility of the parser in recognizing valid Unicode escape sequences. By removing the specific quantifier{1,3}for octal digits and allowing for a broader match of one or more hexadecimal digits, the parser can potentially handle a wider range of input without altering the fundamental logic of the grammar.resources/metavariable-grammars/java-metavariable-grammar.js (1)
184-184: LGTM! The change improves compatibility with Java source code.The updated regex pattern
/u[0-9a-fA-F]+/for Unicode escape sequences aligns with the Java Language Specification, which supports Unicode escape sequences both with and without curly braces.Removing the curly braces
{}from the pattern allows the grammar to correctly match and parse Unicode escape sequences in the non-braced form, such as\u1F600, in addition to the braced form\u{1F600}.This change improves the grammar's compatibility with Java source code that uses the non-braced form of Unicode escape sequences.
crates/core/src/test.rs (1)
8843-8884: Looks good!This is a well-structured test case that covers the parsing of Java import statements based on the defined patterns. It distinguishes between Spring-specific imports and generic imports correctly.
The test input includes a good variety of import statements, and the expected output aligns with the pattern logic.

There was a problem hiding this comment.
Invalid Unicode escape sequence pattern.
The modified pattern "value": "u[0-9a-fA-F]+" is not a valid format for Unicode escape sequences in Java. According to the Java Language Specification, Unicode escape sequences must be of the form \u{NNNN} (with curly braces) or \uNNNN (without curly braces), where NNNN is a sequence of 4 hex digits.
Removing the curly braces from the original pattern "value": "u{[0-9a-fA-F]+}" changes the syntax and makes it invalid. The original pattern correctly matches Unicode escape sequences with 1 or more hex digits enclosed in curly braces.
Please revert this change and keep the original pattern to ensure compatibility with the Java specification.
