* Add Dolphin-compatible input expressions and GCPadNew.ini import Rebased onto current main; addresses both CodeRabbit reviews on #89. - Expression engine matching Dolphin's semantics: doubles rather than booleans, 0.5 press threshold, & as min, | as max, and the functions if, min, max, clamp, abs, sqrt, pow, sin, cos, tan, deadzone, timer, toggle, hold, tap, pulse and smooth. Timing uses a steady clock in seconds, as Dolphin does, so a copied expression behaves identically. - Expressions bind to the GameCube buttons and triggers, combined with the existing button mapping rather than replacing it, and are skipped while the settings overlay holds input. - Import reads [GCPadN] from the Dolphin config directory or from GCPadNew.ini beside the executable. Stick axes are not expression driven and keep their normal mapping. - Fixes #74: a digital button bound to L or R now reports a fully pulled analog trigger, plus a PlayStation preset and a vibration toggle. Review fixes: config paths round-trip through RuntimeConfigFile::PathToUtf8 and PathFromUtf8 so non-ASCII paths open correctly on Windows, and the duplicated exists branch is gone; the tap count is clamped before the unsigned conversion; the expression editor uses resizable storage via ImGuiInputTextFlags_CallbackResize so a long expression cannot be saved truncated; clamp bounds are ordered before std::clamp; <cstdlib> is included for std::strtod; non-finite values are rejected at the evaluator boundary as well as at the deadzone and timer divisions; and InputBindings::Reload() runs from InitializeRuntimeSettings rather than the vibration handler. runtime/tests/test_expr.cpp covers operator precedence, each stateful function and every case raised in review. Third review round: smooth() guards NaN as well as infinity so a zero rate cannot latch a non-finite value in node state; division evaluates both operands so stateful functions in the left subtree still update when the divisor is zero; the expression editor clears stale errors when the port changes; and runtime/tests/test_expr.cpp is registered with CTest as mkw_input_expr_tests, following the existing test targets. * Update runtime/src/input_expr.cpp Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update runtime/src/input_expr.cpp Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update runtime/src/input_expr.cpp Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> --------- Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com>
