lintrhelper 0.1.0.9000 (development)

Bug fixes

• forbid_symbols(), create_function_call_linter(), require_naming_pattern(), and require_function_naming_pattern() now correctly return multiple lints when several locations match. Previously the per-node messages were assembled with unlist(recursive = FALSE), which broke the lints object structure and silently dropped all results.
• create_assignment_linter() (and therefore enforce_assignment_operator()) now matches = assignments. The previous XPath assumed the assignment was always wrapped in <expr>, but = lives under <expr_or_assign_or_help>.
• require_naming_pattern() and require_function_naming_pattern() honour the invert argument again — both branches of the conditional were returning the same value.
• require_function_arguments() now inspects the full call expression (the grandparent of SYMBOL_FUNCTION_CALL) when looking for named arguments, so calls that do supply the required argument no longer trigger.
• limit_line_length() is now scoped to the file level (it used to run once per expression and rely on a non-existent $lines field).

Tooling

• Added GitHub Actions workflow for R CMD check across macOS, Windows, and Ubuntu (R devel/release/oldrel-1).
• Added pkgdown workflow that deploys the documentation site to https://fabiandistler.github.io/lintrhelper/.
• Added _pkgdown.yml configuration grouping the reference index by user-facing categories.
• Generated man/ pages from existing roxygen comments (R CMD check previously failed because no Rd files were committed).
• DESCRIPTION: real author, declared utils as an import (for capture.output), dropped the unused rlang import, dropped LazyData (no data/ directory).

lintrhelper 0.1.0

Initial Release

High-Level Functions (No XPath Required!)

The main feature of lintrhelper is that you don’t need to know XPath to create linters:

• Added forbid_symbols() - Ban specific variable names
• Added forbid_functions() - Ban function calls with auto-generated alternative suggestions
• Added require_naming_pattern() - Enforce naming conventions with regex (no XPath!)
• Added require_function_naming_pattern() - Enforce function naming with regex
• Added enforce_assignment_operator() - Prefer <-, =, or ->
• Added require_function_arguments() - Ensure functions are called with specific arguments
• Added limit_line_length() - Enforce maximum line length

Testing Utilities

• Added test_linter() for simplified linter testing
• Added quick_test() for rapid development

Advanced (XPath-Based) Functions

For users who want more control:

• Added create_simple_linter() for XPath-based linter creation
• Added create_function_call_linter() for XPath-based function call linters
• Added create_assignment_linter() for XPath-based assignment operator linters
• Added linter_template() for code templates
• Added xpath_patterns() for XPath reference

Ready-to-Use Examples

• Included example linters: no_t_f_linter(), no_attach_linter(), prefer_arrow_assignment_linter(), no_sapply_linter(), no_one_length_linter()

Documentation

• Added comprehensive README emphasizing no-XPath approach
• Added “Getting Started” vignette
• Added “Creating Linters Without XPath” vignette with extensive examples
• Added unit tests for all functions
