Add workspace-aware Find All References and Rename for scoped locals and
globals, plus registry/apps/dwarf smokes in the default test target.
- bux-lsp: textDocument/references, prepareRename, rename
- make test-lsp runs smoke_lsp_rename; make test includes registry/dwarf/apps
Ship the QUALITY_PLAN stretch from ownership through ecosystem: C.1
lifetime elision (bootstrap + selfhost), bux fmt/test/doc CI hooks,
stdlib goldens, package registry (bux search/add), and LSP 0.4
position-sensitive locals with inferred let types. Full-tree format
pass plus Map/Set remove double-free fix.
Multi-field variants use Enum_Variant_Payload nested types (avoids tag name clash).
Sema resolves data.Variant.Variant_i; enum field types fully resolve tuples.
Selfhost parses full type exprs in enum payloads; emit structs/tuples before enums.
Example: examples/nested_patterns.bux (Pair::Two, Box::Val((a,c)), Shape::Dot).
Blocks can yield a value: last expression statement is the result.
Match arms accept block bodies, so multi-statement arms work:
match n {
1 => { let a = 10; a + 1 },
_ => 0
}
Bootstrap: lowerBlock(asExpr) lifts the trailing skExpr. Selfhost: parse
{...} as ekBlock, emit __blk_N yield temps (retTypeKind -2), and treat
only non-empty strValue as match/block yield. Nested enum/struct pattern
bindings recurse in both compilers.
Example: match_block.bux. Selfhost-loop remains binary-identical.
Support destructuring in match arms:
- Tuple: (a, b) binds subject._0 / _1
- Struct: Point { x: px, y: py } and shorthand Point { x, y }
Bootstrap: matchPatternBindings for pkTuple/pkStruct; register local
tuple typedefs from function bodies. Selfhost: parse, Sema_BindPattern,
Lcx_PatternBindings with scope defines. Fix operator-overload path that
crashed when typeName was null after pattern binds.
Example: examples/struct_tuple_pat.bux. Selfhost-loop IDENTICAL.
Upgrade bux-lsp to 0.2.0 with a richer lightweight symbol index:
func signatures, typed let/var/const, struct/enum/interface/type/module.
Skip comments and strings while scanning. Hover shows markdown Bux
code fences; definition resolves in-file and across workspace .bux files;
documentSymbol provides outline. Fix responses writing to stdout (stdin
was a broken pipe). didChange refreshes symbols; diagnostics still run
via buxc on open/save.
Sessions 10–12 from QUALITY_PLAN:
- Pattern payload bindings (Some(value) => value) in bootstrap and selfhost
- Empty-param closures via || (tkPipePipe) with loop/return bodies
- Expression-form match: let x = match …; newline before arms
- f"…" string interpolation desugared to String_Concat + conversions
- Lexer preserves \{ \} for literal braces in f-strings
- Bootstrap fix: f"plain" strips the f prefix after escape processing
- Examples: pattern_matching, closure_control, match_let, string_interp
Selfhost-loop remains binary-identical; all examples and error goldens pass.
Lower match to if-else for literals, ranges, enum tags, and wildcards.
Fix bootstrap literal arms that always matched; port real arm AST/parser
and Lcx_LowerMatch to selfhost with last-expression return. Expand
pattern_matching example and add parse/use-after-move/double-mut golden
diagnostics. Selfhost-loop remains binary-identical.
Add int-specialized higher-order Iter helpers that accept fat function
pointers, plus an example using named funcs and capturing closures.
Fix selfhost C backend pointer field access and Array Push indexing.
Introduce fat function pointers (BuxFn {code, env}) so capturing closures
are heap-allocated per value in both bootstrap and selfhost. Expand
Array/Map/Set/String/Test/Result APIs, add proper tuple codegen and
error snippets with multi-char underlines, golden diagnostic tests, and
LSP diagnostics via buxc check.
