The lexical-syntax chapter, granularity modeled on jank's 62-file
per-construct reader corpus: token grammar (whitespace/comments, collections
with read-time duplicate checks, numbers incl. the N/M tower question,
symbols/keywords incl. ::auto-resolution, strings/chars), the quote-family
sugars, the full #-dispatch catalog with normative entries (anonymous fn
%-derivation, discard composition, reader conditionals, symbolic floats,
tagged literals), and the syntax-quote contract (core/alias/current-ns
qualification, template-stable gensyms, ~' idiom, distribution through
collections).
Adapting the corpus surfaced and filed three findings, recorded as labeled
divergences/UNVERIFIED in the chapter: nested syntax-quote doesn't collapse
(S25, (= "meow" ```"meow") is false), #inst reads as a bare string (identity
data reader, no instant type), and jolt satisfies :clj in reader
conditionals (feature-key policy under review).
reader-forms-spec gains 11 chapter-cited rows (discard stacking, ##Inf/
##-Inf/##NaN, :default conditionals, qualified var-quote identity, gensym
stability within vs across templates) — all passing.
Fifteen vars from the spec coverage gap (docs/spec/coverage.md):
parse-long/parse-double/parse-boolean (strict validation; scan-number alone
accepts 0x10), newline, current-time-ms (host clock for time), update-keys/
update-vals (PHM base, collisions last-wins), partitionv/partitionv-all/
splitv-at (lazy seqs of vectors; splitv-at's tail stays a seq, matching the
reference), with-redefs/with-redefs-fn (roots restored on throw), time,
macroexpand (expand-1 to fixpoint), alias/ns-unalias (write BOTH alias stores
— require :as uses string-keyed :imports while ns-aliases reads :aliases;
split filed), ns-publics (symbol-keyed map; publics == interns, no privacy).
Three pre-existing bugs fixed along the way:
- (partition n step pad coll) misparsed pad as the coll and returned ()
- (require 'bare.symbol) rejected — only vector specs were accepted
- analyze-form leaked the interpreted analyzer's ns on a punt: a throw out of
the analyzer left current-ns=jolt.analyzer and :compile-ns set, so the
fallback interpretation resolved user vars against the wrong namespace
(bit (var user-sym) under compile mode)
And one overlay-authoring landmine documented in-code: a 20-coll fn must not
use 30-macros macros (with-redefs-fn's dotimes compiled as a forward ref that
resolved to the macro fn at runtime) — loop/recur instead.
Gate: conformance 316x3 (+14 rows), suite 4324 pass / 78 clean (was 4081/72;
parse_*/update_* files now contribute), baselines raised, all specs+unit,
fixpoint, self-host, sci, staged. Coverage: missing-portable 35 -> 20.
RFC 0001 proposes a normative, implementation-independent Clojure language
spec (the reader, evaluation model, special forms, data types, seq/laziness
contracts, namespaces/vars, and the portable clojure.core surface) to the
standard of R7RS/Racket — Clojure has none, and every alternative
implementation re-derives semantics from the reference and folklore. The
spec is executable-first: every numbered normative statement cites its
conformance test or is marked UNVERIFIED.
docs/spec/ carries the front matter (conformance terms, entry format, host
classification), the special-form catalog with worked normative entries for
if and let*, the core-library entry format with worked entries for first,
reduce, and parse-uuid, and a generated coverage dashboard over the 694-var
ClojureDocs inventory (tools/spec_coverage.py cross-references the surface
against jolt's interned+resolvable vars and the test suites).
Measured baseline: 380 implemented+tested, 154 implemented-untested, 35
portable-but-missing (filed), 22 resolvable-but-not-interned (filed — seed
fns invisible to resolve/ns-publics), rest classified host/JVM/concurrency.
