Julia Fibonacci
Julia typed Fibonacci with a for-loop — realistic snippet for language tooling.
function fib(n::Int)
a, b = 0, 1
for _ in 1:n
a, b = b, a + b
end
return a
end
println(fib(10))

What is a .jl file?
Julia (.jl) source files contain programs written in the Julia language, used for scientific computing with multiple dispatch and high-performance numerics.
How to use this file
Use example .jl files to test Julia syntax highlighters, language servers, and formatters against short known-correct and intentionally invalid samples.
How to use this file for testing
“Julia Fibonacci” is a deterministic Novus Examples fixture for Syntax highlighting, Code parsing, Editor testing. Idiomatic hello-world programs and realistic snippets across sixteen languages, exercising comments, string escapes, interpolation, numeric literals, and language keywords — for testing syntax highlighters, editor themes, and tree-sitter grammars.
Documented properties for this file: idiomatic sample · julia · LF. 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.
