Functions

edit_distance

Compute the Levenshtein edit distance between two strings.

find_closest_match

Find the closest match to name among candidates, within max_dist edits.

harness_clock_replacement

Map an ambient clock-capability builtin to its harness.clock.* replacement. Returns the new identifier text (including the receiver path) so the bindings/thread-harness-clock repair can replace the call-site identifier in place. The mapping is the source of truth for the E4.3 → E4.6 migration; downstream replatform agents query it via [Code::repair_template].

harness_env_replacement

Map an ambient env-capability builtin to its harness.env.* replacement. Backs the bindings/thread-harness-env repair.

harness_fs_replacement

Map an ambient fs-capability builtin to its harness.fs.* replacement. Backs the bindings/thread-harness-fs repair the E4.4 → E4.6 migration uses to rewrite .harn scripts off the legacy surface.

harness_net_replacement

Map an ambient net-capability builtin to its harness.net.* replacement. Backs the bindings/thread-harness-net repair. Only the basic verb surface is migrated mechanically; streaming, session, and server-mode builtins keep their ambient names today.

harness_random_replacement

Map an ambient random-capability builtin to its harness.random.* replacement. Backs the bindings/thread-harness-random repair.

harness_stdio_replacement

Map an ambient stdio-capability builtin to its harness.stdio.* replacement so harn fix can replace the call in place once the relevant harness binding is available.

lexer_error_code

normalize_diagnostic_path

Normalize diagnostic filenames lexically for display.

parser_error_code

parser_error_help

parser_error_label

parser_error_message

renamed_stdlib_symbol

Return the replacement for stdlib symbols that were directly renamed.

render_diagnostic

Render a Rust-style diagnostic message.
