lexLine had grown into one long function trying dates, hex/bin/oct,
grouped numbers, decimals and xrefs inline. Extracted each into a
tryLex* helper with the same fallback order, so the driving loop
reads as a priority list instead of nested ifs.
Covers detectDateOrder, resolveZone, addToDate and isCalendarUnit —
none of it had direct unit coverage before, only indirectly through
the engine's date-arithmetic tests.
Besides ISO, the lexer now accepts D.M.YYYY / M/D/YYYY literals
(31.12.2024, 12/31/2024) with a round-trip validity check so
out-of-range components (2026-13-45, 32.13.2024) fall back to plain
arithmetic instead of silently rolling over to a nearby valid date —
that rollover bug affected ISO literals too, not just the new forms.
Day/month order for ambiguous literals and display layout both come
from a new dateFormat setting (system/iso/dmy/mdy); "system" resolves
once via Intl against the OS locale. Intl.DateTimeFormat instances
are now cached by options key instead of rebuilt on every render.
App-side wiring (settings UI, persistence) comes in a follow-up commit.
The 290-line function is now registerCoreVocab / registerUnits /
registerAreaVolume / registerCurrencies / registerExtraUnits /
registerCrypto / registerCompletions, called in the same order —
phrase-collision priority depends on that order, unchanged. Pure
reorganization, no behavior change.
rawLine.indexOf("//") matched the "//" inside "https://..." too, so
any line with a URL lost everything after it. A comment now only
starts at the beginning of a line or after whitespace.
Two independent traps. The noise filter only keeps word tokens right
after a conversion token (in/as/...); any other token type resets
that, so the "/" in a slash-form IANA id ("Europe/Berlin") reset it
before the parser ever saw "Berlin". The word-collecting loop in
parseTarget() had the same blind spot even once the token was there.
Both needed the same exception, or "Europe/Berlin" still degrades to
just "Europe".
"exp" was also listed as a scientific-notation alias ("123456 in
exp"). Phrases register first-come-first-served, and that alias was
registered before the exp() function, so the function itself never
got the phrase — exp(1) parsed as a bare (1) and returned 1. Drop
exp from the scientific-notation aliases; sci/exponent/exponential
still work.
"2 kg * 500 g" multiplied the raw numbers (1000) and slapped the
left unit on top, giving "1000 kg" instead of "1 kg". Convert the
right operand into the left unit first for same-dimension products;
cross-dimension multiplication ($12 * 3, 5 hours * 2) is unaffected.
evalCall checked args[0] and threw "needs an argument" before ever
falling into the random case, which is the one built-in that's
valid with zero args. Dispatch it first.
In an A<->B cycle, exportsFor(B) run while A is mid-resolution would
compute a wrong export set (assignments dropped by the nested
"circular reference" error) and cache it anyway. Later queries then
served that stale, cycle-broken result even after the cycle-causing
outer call had unwound, giving inconsistent error messages across
repeated evaluations of the same cyclic setup.
Skip caching whenever any line in the result carries a "circular
reference" error - that's a precise, local signal the pass was
cycle-affected, so the sheet gets re-evaluated fresh until an edit
actually breaks the cycle. Normal (non-cyclic) caching is untouched.
Also adds a positive-path test confirming LineResult.error stays
undefined on an ordinary successful line, and a workspace-level test
proving a genuine cycle now reports a stable error across repeated
queries.
