Changelog

All notable changes to the punkshell project version are documented here. The latest ## [X.Y.Z] header must match the version field in punkproject.toml. Entries are newest-first; one bullet per notable change. See the root AGENTS.md "Project Versioning" section for the bump policy.

[0.4.7] - 2026-07-08

• G-036 completed (flipped to achieved): punk::lib 0.3.0 adds punk::lib::check::has_libbug_udp_threadexit — version-based detection of the tcludp < 1.0.13 thread-exit bug on Tcl 9 Windows (the per-thread exit handler closes process-global event handles, silently freezing every other udp-using thread's event loop after any udp-loaded thread exits; root-caused and fixed-by-upgrade earlier in 0.4.3). has_libbug_* is the new check family for bundled/vendored library bugs; help tcl (punk 0.2.1) now scans it alongside has_tclbug_*, supports a full url reference key for non tcl-core trackers, and no longer errors on a triggered check carrying a reference without a description. Detection is loaded-version based, falling back to the best available registered version without loading the binary. New checkbugs.test covers the classifier matrix, the live check's dict shape/consistency, and a contract test over all existing check procs. Open decisions recorded in the G-036 detail: punk8win (8.6) kit's udp 1.0.12 swap; optional upstream tickets for residual tcludp trunk weaknesses.

[0.4.6] - 2026-07-08

• punk::ns 0.1.1: five development trace puts removed from the command doc-lookup machinery — "PROC auto def"/"ENSEMBLE auto def" from generate_autodef were emitted on STDOUT and polluted i/s output in script/exec contexts (visible to agents piping i <cmd> per the G-015 pattern); "skipping to documented subcommand", "cmd_traverse ensembleparam" and the "cmd_traverse 10 ... review" fallthrough note were stderr noise on the space-form-id, ensemble-parameter and undocumented-tail traverse paths. No functional change.
• punk/ns cmdflow.test: 8 new tests characterizing ensemble -parameters handling in the doc-lookup flow (the punk::netbox::man pattern — a leading apicontextid before the subcommand): generate_autodef models each parameter as a -ensembleparameter 1 leader with @leaders min/max = nparams+1 (single- and two-parameter fixtures), cmd_traverse consumes parameter words and resolves the subcommand's explicit or autodef docid (re-presenting the parameter in args_remaining for the subcommand's own leader parse, matching punk::netbox::man's explicit defs), nested sub-ensembles with their own -parameters re-consume the curried parameter at each level, parse treats -ensembleparameter leaders as ordinary named leaders, and cmdhelp renders a documented subcommand's usage through the parameter.

[0.4.5] - 2026-07-08

• punk::args 0.2.3: fixed @opts -any 1 (arbitrary/adhoc option passthrough) — an option not present in the definition crashed parsing with "can't read argname" instead of passing through with its value (real consumers: vendored tomlish definitions declare -any 1); silenced a debug puts stderr that fired on every failed clause type assignment (visible on any multiform parse miss). Found while building the punk::args comprehensiveness pass.
• punk::args test suite expanded (94 tests, was 71 at start of day): new forms.test characterizes multi-form (@form) parsing and pins the G-041 gaps — parse without -form is effectively form-0-only, -form rejects the documented list-of-forms usage, and the @form -synopsis override is stored but ignored by synopsis rendering; new validation.test covers the -type validation matrix, -range/-minsize/-maxsize, -nocase choice normalization, option -multiple accumulation, required-option enforcement, unknown-vs-adhoc option handling, the -- end-of-options marker, @values -max enforcement, received-key clause ordinals, solos, and default-vs-received distinction.

[0.4.4] - 2026-07-08

• punk::args 0.2.2 (doc-only): the punk::args::define documentation for the -choice* fields now spells out the verified interplay semantics — -choicerestricted 0 passthrough of non-matching/ambiguous/denied/reserved words, -choiceprefix normalization of accepted prefixes to the canonical choice in parse results (with minimal-prefix highlighting in usage display), and the -choiceprefixreservelist phantom-entry idiom for per-choice minimum-prefix control. Characterization tests added (choices.test unrestricted-mode tests; new punk/ns cmdflow.test for the cmdwhich/cmdinfo/cmd_traverse docid flow, pinning the parse-vs-doc-walk deny/reserve divergence as GAP pending G-040).
• help system restructured onto a topic registry (punk module 0.2.0, ::punk::helptopic): each topic (topics|help, tcl, env|environment, console|term|terminal) is a handler proc with its own punk::args definition, and the ::punk::help/::punk::help_chunks definitions are (re)generated from the registry — i help now renders a documented usage table with topic choices and summaries, and i help <topic> shows per-topic documented usage (previously an autogenerated stub). help topics is derived from the registry (lists all aliases, fits 80 columns). No-arg overview and command-fallthrough (help <cmdname>) output byte-identical to before; 80-column layout preserved; verified on both generations, script and shell subcommands. help env without an initialised punk::config (e.g. script contexts) degrades to a one-line notice instead of an error stack. The registry is the intended seam for future subshell-declared topics (punk::config-gated — not yet a goal).

[0.4.3] - 2026-07-08

• vendored tcludp upgraded 1.0.12 -> 1.0.13 in the tcl9 kit vfs folders (punk9win.vfs, punk9win_for_tkruntime.vfs) and src/vendorlib_tcl9 — 1.0.12's Windows per-thread exit handler closed the process-global tcludp synchronization events, so the first udp-loaded worker thread to die froze every other udp-loaded thread's event loop (root cause of the G-036 wedge; fixed upstream in 1.0.13). Verified with the G-036 regression harness: run-2 syslog workers alive (baseline on 1.0.12: wedged 4/4). Note: punk8win.vfs still bundles udp 1.0.12 (8.6 appeared immune; pending decision). The manual vfs copy was required because libs/vfscommonupdate/project do not propagate vendorlib_tcl platform libraries into kit vfs lib_tcl trees — gap recorded as goal G-037.

[0.4.2] - 2026-07-08

• piped-stdin exit/quit hang fixed (shellthread 1.6.3, shellfilter 0.2.4): repl/app teardown no longer blocks forever when a shellthread worker's event loop has wedged — unsubscribe's settings-reset send is now async, shutdown_free_threads keeps its timeout armed across all waits, and shellfilter::run honors its -syslog option (default empty -> no runtag log worker thread) instead of a hardcoded 127.0.0.1:514 debug leftover. Syslog remains supported when explicitly configured. Diagnosis and residual root-cause work tracked as goal G-036.

[0.4.1] - 2026-07-07

• script subcommand now matches tclsh for GUI scripts: if the script leaves a registered Tk main loop (Tk loaded with a live main window), the event loop is serviced until the last window closes, instead of sourcing-then-exiting immediately. So a Tk script with no explicit exit (or one that exits from an after callback, like scriptlib/tktimer.tcl) stays alive and runs — previously it flashed and died, and shell was needed as a workaround (relevant to G-020 GUI automation). Console scripts are unaffected; a script that errors exits at once (no hanging window). Verified on both generations.

[0.4.0] - 2026-07-07

• script subcommand supports lib:<name> scriptlib scripts (with or without .tcl extension), matching the shell subcommand's scheme: punkexe script lib:hello, or bare punkexe lib:hello via reclassification. The prefix always wins — a literal path beginning lib: (pathological; illegal on Windows filesystems) is reachable via ./lib:.... Not-found errors list the searched locations. Only .tcl runs via the script subcommand.
• punk::path 0.2.2: new scriptlib_resolve — the shared lib: resolution policy (kit-internal app/scriptlib first and not externally overridable, then scriptlib dirs relative to the executable), PUNKARGS-documented. app-punkshell still carries its inline copy of the policy (refactor onto the shared proc noted as todo).

[0.3.1] - 2026-07-07

• script subcommand: core-command documentation parity with the interactive shell — app-punkscript now loads punk::args::moduledoc::tclcore (catch-guarded, ~40ms) so e.g. 'i list' | punkexe script renders the doc table instead of "Undocumented command". Verified on both generations; kit startup ~0.33s.
• punk::packagepreference 0.1.1: the moduledoc auto-load success notice moved from stdout to stderr — stdout must stay clean for script/exec contexts (the failure branch already used stderr).

[0.3.0] - 2026-07-07

• <punkexe> script completed (goal G-015 achieved): runs a script file (script <file> ?args?, conventional ::argv0/::argv) or the whole of piped stdin (<commands> | <punkexe> script — no trailing exit needed) in the default punk shell module/alias environment, so one-liners like dev projects.work *name* work with no boilerplate. Honest exit codes (0 success, 1 error with errorInfo on stderr, script's own exit honoured); no shellfilter transforms or logging side effects; never falls into an interactive shell. Implemented as the lean app-punkscript package; the stdin form echoes the script's final result when non-empty. Verified on both Tcl generations (punk902z, punksys).

[0.2.7] - 2026-07-07

• vendored tomlish 1.1.10: the library API now carries punk::args (PUNKARGS) documentation (from_toml, to_dict, from_dict, to_toml, update_tomlish_from_dict) — the G-014 tomlish precondition is met (documented upstream, re-vendored from a clean checkout); plus the explicit tomlish::cmdline_main entry point.
• _vfscommon.vfs kit payload refreshed to the current built modules: shellfilter 0.2.3, shellrun 0.1.4, punkboot::utils 0.1.1, punk::console 0.7.1 content catch-up, tomlish 1.1.10.

[0.2.6] - 2026-07-06

• shellfilter 0.2.3: shellfilter::run now guarantees tee-stack removal (stdout/stderr restoration) via try/finally even when its body errors, and the decorative stack-status table rendering in log::critical blocks is catch-guarded. Previously an error there (observed: a stale same-version textblock snapshot calling the new punk::ansi sgr_merge_singles with old option syntax) aborted the run between channel diversion and restoration, leaving the process's stdout/stderr broken and all subsequent output silently lost.
• runtests.tcl: testinterp tm path order fixed so the bootsupport snapshot wins same-version module ties over vendormodules (verified rule on Tcl 9.0.3, standard and punk::libunknown scanners: tcl::tm::add prepends, head of tcl::tm::list wins ties, so the last test_tmlist element wins); testinterp auto_path gains the parent of [info library] so binary packages such as Thread resolve in projects without a root lib_tcl<N>/<arch> payload.

[0.2.5] - 2026-07-06

• make.tcl vendorupdate now checks each vendor source project's fossil/git checkout state and warns (non-fatal, once per VCS root) when pulling from a dirty tree — vendored artifacts built from uncommitted source have no committed provenance. Enforcement policy (abort/override, bootsupport coverage) tracked by goal G-026.
• punkboot::utils 0.1.1: the dirty-checkout check lives in the module as vcs_dirty_warnings (make.tcl calls it via a guarded lazy require and degrades to skipped if the bootsupport snapshot lacks it); bootsupport snapshots refreshed (punkboot::utils 0.1.1, shellrun 0.1.4, punk::console 0.7.1 content catch-up).

[0.2.4] - 2026-07-06

• shellrun 0.1.4: added missing package require punk::args (the 0.1.3 migration left runx/run/runout/runerr calling punk::args::parse without requiring it, breaking shellrun in bare interps — including the src/tests/runtests.tcl testinterp, which made every source-tree test run fail).

[0.2.3] - 2026-07-06

• shellrun: removed -tcl from sh_run, sh_runout, sh_runerr, sh_runx (was silently swallowed with no useful effect because sh -c is always an external shell; now rejected with a usage message).
• shellrun: migrated runx from the legacy get_run_opts parser to punk::args::parse with a full PUNKARGS spec; runx now honours -debug and --timeout= (previously accepted but silently ignored).
• shellrun: expanded PUNKARGS documentation for run, runconsole, runout, runerr, and runx with @cmd metadata and -help text on all opts/values.
• shellrun: migrated sh_run, sh_runout, sh_runerr, sh_runx from get_run_opts to punk::args::parse with dedicated PUNKARGS specs.
• shellrun: removed the internal get_run_opts proc; all callers now use punk::args.

[0.2.2] - 2026-07-06

• punk::console: terminal queries fired while an 8.6-based shell waits at an idle line-mode prompt now fail fast with a discriminable errorcode (PUNK CONSOLE QUERY HOSTAGE_COOKED_READ) and emit nothing, instead of timing out (~500ms) and later corrupting input with the swallowed response (idle-reader hostage guard; raw mode and mid-command queries unaffected). Owner-routed queries preserve the owner-side errorcode.

[0.2.1] - 2026-07-06

• make.tcl projectversion: new advisory subcommand verifying CHANGELOG.md matches punkproject.toml and warning if src/ has commits since the last project-version bump.
• Clarified project versioning policy: the make.tcl command interface is part of the product surface.

[0.2.0] - 2026-07-05

• Initial tracking of the punkshell project version in punkproject.toml.
