ack	240cff4278	An output policy for the three commands, and @cond as a true special form ... A snapshot of the development tree. The substantial changes since the last one: COMMAND OUTPUT POLICY. The three commands display text in exactly three cases, and each owns a stream: LOGGING under "-v" greater than 0 and an ERROR before termination go to STDERR; OUTPUT THE USER ASKED FOR goes to STDOUT. For ktext that output is a document, so "ktext doc.kt -d | ..." is now safe -- logging used to share the stream and land inside the document. A bare command prints its usage and succeeds rather than failing. Colour is emitted only to a terminal, per stream, and NO_COLOR is honoured. "-v 1" reports every decision whose outcome you could not have read off your own input: the klammerset that was loaded and from which file, a font's directory, a ":files" name's file, how "-o" was expanded. Higher levels are the trace. The commands no longer warn and continue: an anomaly is an error, described with its location. Two exceptions remain, each for a stated reason -- a condition that is expected and temporary by design, and a judgment that is a heuristic rather than exact. @cond IS NOW A TRUE SPECIAL FORM, resolved at APPLICATION time rather than when the file is read. Two consequences for a writer: * a state variable reaches the predicate. "@@@state Flag :value true @@@ @cond *Flag* | T | F @" renders "T"; it used to see the literal "*Flag*" and silently take the false branch. The document now behaves like a klammer body, whose arguments are bound before its conditionals are decided. * nothing in a discarded branch happens -- it is not read, not evaluated, not expanded. An @eval in the branch not taken used to run anyway. Its predicate relation is total and strict: true, True, 1; false, False, 0, and empty; anything else is an error at the @cond rather than silently false. @eval REACHING OUTSIDE. ":shell" and ":haskell" now keep the command's standard error out of the document (it appears under "-v 1") and treat a nonzero exit as an error naming what the command reported. A command that exits nonzero on purpose -- "grep" finding no match -- says so with "|| true". KLAMMER SETS. Several combine: "--klammersets a b c" loads all three in the order given, sharing one namespace, with the definition modes deciding collisions. "none" means none and may not be combined with other symbols. A klammerset with symbol X is declared in a file X/X.k, which is what lets two sets require the same third set without loading it twice. TESTS. Four new suites: the kdiag command's interface, the @eval primitive's contract with the outside world, and verbosity at both tiers. Three suites that could not run on macOS at all now do.

ack	59c1599bc9	Target coverage: a klammer states the targets it serves ... kdesc gains --coverage, which reports for every klammer the set of targets it can render to, and — the point of it — which klammers' coverage cannot be derived and must therefore be declared. Three rules: coverage is DERIVED where the definitions determine it (a general body of klammer calls covers the intersection of what those klammers cover, by a greatest fixpoint after loading), DECLARED where the engine cannot interpret what decides it (an @eval body, whose targets are undecidable), and UNKNOWN where nothing is written — which never means "deliberately unavailable". Two new spellings in a definition's name. A comma-separated target list, "@@table.html,tex :: ...", gives one body several targets; it is surface syntax, expanded at registration, and each member goes through the redefinition rules on its own. And "@@date.* :: ..." writes the general target out, asserting that the klammer works for EVERY target including ones not yet defined — a stronger claim than a list of the targets defined today, and the one target declaration that could be mechanically falsified. The Standard Klammer Set was swept accordingly: it now has no general definitions at all, every klammer names the targets it serves, six use ".*", and tex and pdf are at zero undecided. kdesc's flags are reorganised on two rules: a flag reached for often gets a single letter (-k klammers, -t targets, -c characters, -i input), a more specialised topic a multi-letter name (--argtypes, --katoms, --rewrite, --optionsets, --coverage, --klammerset, --font); and -v says how much to show about PROCESSING, never what the RESULT contains — so the katom regex column is "--katoms full" and the coverage detail "--coverage all". NOTE: "-k" now lists klammers (optionally filtered by a name/description search); the katom table moved to "--katoms". Fixes carried along: an option written with no value crashed the command with SIGSEGV instead of reporting the mistake; two required positional arguments never parsed; kdesc and kdiag printed an error and exited 0; and definition diagnostics counted registrations rather than what was written, so one line could be reported as two definitions and then printed twice. Four new test suites: target_list, coverage, command_option, kdesc. (from dev 46f54080bd9a)	2026-08-12 17:20:23 +02:00
