⍋ GNU APL Test Suite Coverage

Generated July 21, 2026 at 18:13

What is this? This report shows the results of running our own APL interpreter (the Rust/WASM engine that powers aplrun.com) against the official GNU APL test suite — 1782 assertions covering primitives, operators, system functions, formatting, and control flow. This is not GNU APL itself; it is our independent implementation being validated for compatibility. Each assertion compares our interpreter's output to the expected result defined by the GNU APL test cases (src/testcases/*.tc).
