Add expression parser for CLI transforms parity#101
Merged
Conversation
…ctors Add parse_expr() — full recursive descent parser for ranking expressions from CLI strings. Supports all transforms (ascending_cdf, descending_cdf, logistic, clip, hinge, log, log2, log10, log1p, exp, sqrt), arithmetic, aggregations (mean, geomean, minimum, maximum, median), column() refs, wt() wrapper, and method qualification via brackets. Extend --rank-by to accept expression strings alongside simple kind names. Use mhctools predictors_from_args() so --predictors flows through from mhctools. Require mhctools>=3.4.0. Bump version to 4.7.0. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
