Activated and completed under user direction (2026-07-08). Aliases for choice
values are now first-class: accepted at parse, normalized to their canonical
choice in results, folded into the canonical entry in usage display, and
resolved identically by the punk::ns doc-lookup walk.
- punk::args 0.3.0:
* -choicealiases {alias canonical ...} on argument lines; dict shape
validated in the option switch, alias->existing-choice and no-collision
cross-validated after spec merge (surfaces at resolve time - define is
lazy)
* the choice-word matching chain extracted from get_dict into the shared
resolver punk::args::choiceword_match {word nocase allchoices
choicealiases choiceprefix denylist reservelist} -> {matched exact
canonical}; get_dict delegates to it (writeback/lset logic stays at the
call site) - one implementation for parser and doc walk
* exact aliases match under any -choiceprefix/-nocase setting; alias names
join the prefix-calculation pool when -choiceprefix is true; deny applies
to the matched NAME (denied alias requires the full alias; a canonical
reached via its alias is exempt from the canonical's own deny entry)
* display: aliases fold into the canonical entry as an '(alias: x)' /
'(aliases: x|y)' label note (single convergence point covers all render
paths); alias names join the display prefix calculation so highlighted
minimal prefixes stay truthful
* define doc gains the -choicealiases section
- punk::ns 0.1.2: cmd_traverse resolves subcommand words via choiceword_match
- -choiceprefixdenylist/-choiceprefixreservelist now honoured in doc lookup
(the two pinned parity GAP tests flipped to agreement), aliases normalize
before choiceinfo lookup, -nocase honoured in the walk
- punk 0.2.3: punk::help adopts the feature - 'i help' lists one entry per
registered topic (topics+help, tcl, env+environment, console+term|terminal);
topic words accept aliases and unique prefixes with the user-decided
minimum-prefix policy recorded in ::punk::helptopic: denylist {help}
(h/he/hel stay command words), reservelist {c to tc} (fall through to
command lookup; e/en and te/ter fall through naturally as ambiguous).
Argless 'help' output byte-identical to the strict-80 baseline.
- tests: choices.test +5 (alias exact/prefix normalization, noprefix exact-
only, nocase, the punk::help policy matrix, resolve-time validation);
cmdflow.test parity tests flipped from GAP to agreement + alias-traverse and
display-fold assertions (+flowaliased fixture)
- suites: punk/args 98 pass + 1 skip, punk/ns 28 pass, punk/lib 21 pass
- G-040 flipped active -> achieved 2026-07-08; detail file records
implementation and verification
- project 0.4.10 (CHANGELOG entry)
