Blank lines between a block scalar header and its first content line come
before the indent token, so the earlier blank-line capture skipped them.
Buffer leading blanks while the block indentation is still pending and
flush them as empty content once the indent is established, in the shared
indentation path used by both scan loops. Also fix folded bodies to emit
a break for a leading blank rather than folding it into a leading space.
This closes the last block-scalar blank-line edge from #57.
emptyDocument, expectedMappingKey, and tabIndentation were never thrown
anywhere in the parser. Empty and comment-only documents parse to null,
the mapping-key path throws unexpectedToken with an "expected mapping
key" message, and tabs in indentation are reported by the validation
layer's PreflightScanner rather than the parser. Drop the dead cases and
their switch arms and description test assertions. No reachable behavior
changes; the PropertyMutation.tabIndentation test mutation is unrelated
and untouched.
A folded block scalar folded every non-blank line into the surrounding
text, including more-indented lines, which YAML keeps literal with their
line breaks. Detect a more-indented line by its retained leading
whitespace and keep the breaks adjacent to it instead of folding them.
Plain and blank-line folding are unchanged.
The scanner dropped every blank line within and after a block scalar, so
a literal block lost internal blank lines, a folded block turned a blank
line into a space rather than a newline, and the keep indicator could not
preserve trailing blank lines. Capture blank lines as empty content in
both the batch scan loop and the streaming TokenCursor loop, which had
drifted as duplicate copies. Rework blockScalarValue to apply literal
versus folded line semantics and clip/strip/keep chomping over the
captured lines; content without blank lines is unchanged. Re-pin the
multiline-scalar test whose expectation encoded the old dropped-blank
behavior, and add a chomping-and-folding test matrix.
The scanner consumed the `+` indicator of a `|+` / `>+` block scalar but
mapped it to nothing, so keep was silently treated as clip, and a scanner
test baked that in. Add a `keep` case to BlockScalarChomping, recognize
`+` in the header scanner, and correct the test. Full keep value semantics
(preserving trailing blank lines) depend on scanner blank-line capture and
are tracked in #57; this commit fixes the token classification only.
Split the six files that declared multiple sibling types under one
namespace extension so each file declares exactly one top-level type:
the Tagged node component types (Node, NodeKind, Scalar, Sequence,
Mapping, Pair), the validation report types (Report, Source,
SourceReport, BatchReport), DiagnosticKind, TokenKind, ScannerFlowContext
kind, and the event-stream composer helpers. Public type names are
unchanged; the shared report-rendering helpers move from file-private to
internal so the split report types still reach them.
Make check-namespacing.sh namespace-aware: the previous column-anchored
scan was blind to types declared inside indented extension blocks, so it
passed while the rule was violated. It now counts direct members of a
PureYAML namespace extension and ignores nested types and private helpers.
The buffered and streaming event composers each carried an identical
copy of the merge-key (<<) override logic and its invalid-value error.
Extract both into one internal Parsing.MergeResolution helper so the
precedence rules (local keys win, earlier sources win, inherited then
local order) have a single source of truth. No behavior change; all
tests pass.
Add structured validation diagnostics, JSON and Yams comparison gates, and lazy token/event parsing so production behavior is measured without retaining full intermediate parser arrays.
Add internal parsing events with marks, scalar styles, collection styles, alias events, and anchor/tag metadata. Add golden parser event tests for current block parser behavior.
