Testing contract

Expected to fail
Scenario
Parse the file with a Clojure parser or compiler and inspect the diagnostic.
Expected result
Parsing fails because the parameter vector `[x` is never closed - note the parentheses do balance, so only the square bracket is unmatched; the reader must report EOF while reading a vector; a paren-counting editor that ignores brackets will wrongly call this file balanced. The file is 27 bytes over 2 lines, so the whole defect is visible at once and the reported position can be checked exactly.

What is a .clj file?

Clojure (.clj) source files contain Lisp-dialect programs for the JVM, emphasizing immutable data and macros.

How to use this file

Use example .clj files to test clj-kondo-style linters, highlighters, and balanced-form parsers.

How to use this file for testing

“Clojure — Intentionally Invalid” is a deterministic Novus Examples fixture for Error handling, Code parsing, Editor testing. Deliberately corrupt and invalid files, clearly labelled, for testing how your tool fails.

Documented properties for this file: intentionally invalid · clojure · intentionally invalid. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.

Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such, expect parsers to fail loudly rather than silently accept them.

This is a short, known-correct source file. Run it through your syntax highlighter, linter, formatter, tree-sitter grammar, or parser, and open it in the in-browser editor to tweak and re-download. Each snippet exercises comments, string escapes, literals, and language keywords.
