bux-lsp 0.17 publishes in-process diagnostics on open/change/save so
editors show red squiggles for lex/parse/type errors in the live buffer.
VS Code client discovers tools/bux-lsp, adds status bar/restart, richer
syntax/snippets, and docs (docs/LSP.md) for forum/editor setup.
Desugar `is` to tag/value equality in bootstrap and selfhost so LIR
no longer drops hIs as false. Resolve monomorphized Result/Option type
names for `?` (_Tag/_Data). Call bux_exit(1) after Unwrap panic messages.
Add is_operator example and document follow-up fixes.
Replaced fixed-size locals (c0..c7) with O(n^2) linked-list walk
that handles arbitrary case counts via reverse-index traversal.
Added switch.bux test with 11 and 10 cases.
Mark LanguageRef as normative, add docs index, update README/Packages/
Stdlib/BuildAndTest status lines, archive PLAN.md and QUALITY_PLAN
pointers to RELEASE_v1.0.0 and active SEMVER.
Sessions 56–69: declarative macro! with rep/zip/literal/block and
unhygienic var $name binders; partial field-move skip Drop; @[Release]
polish; LSP type hierarchy; CI Nim cache + lean macOS + Windows smoke.
Add Ast_Graft/Clone/Quote helpers, HIR Lcx_GraftSourceFile, and force
definition-site paths on monomorphized bodies. Smoke checks Array mono
#line stays in lib while Main stays isolated.
Add .github/workflows/ci.yml (Nim + gcc → make test). Keep selfhost-loop
as an optional/weekly job. Document CI layout; reformat hir_lower for fmt-check.
Add tools/selfhost_loop.sh with path-normalized C and stripped ELF
checks (bootstrap ×2). Wire GitHub Actions (manual/weekly/main paths)
outside default make test. Raise selfhost lexer maxTokens for large files.
Stamp each HIR node with Decl source path; C backend tracks lastDebugFile
so #line re-emits when file or line changes. Closures inherit the
enclosing function path. Smoke checks Util_Double body maps to Util.bux.
Index interface methods and extend Type for Trait relations so call
hierarchy can show implementors as outgoing targets and .Method call
sites as incoming.
- interface I { func M } + extend T for I tracking
- prepare/outgoing/incoming with data Iface#Method
- smoke_lsp_iface_hierarchy (Drawable.Draw ↔ Circle / Render)
Add rtkMethod so .Method( call sites rename with the method decl, improve
type renames across extend/annotations, and clip self to the enclosing
method body.
- Len→Length includes self.Len(); Point→Vec2 hits extend + types
- self→this stays within one method (textual func bounds)
- smoke_lsp_rename_method + test-lsp wiring
Add tools/smoke_selfhost.sh and make test-selfhost-smoke (via make selfhost)
to the default make test suite, covering field-move ownership and per-file
#line paths under buxc2.
Stamp each merged .bux path onto decls, propagate to HirFunc, and emit
#line N \"path\" per function without requiring BUX_DEBUG_FILE.
- Decl.sourceFile + Cli_StampSourceFile on merge/project parse
- HirFunc.sourceFile; CBE switches currentFile per function
- Stdlib and multi-file user packages get distinct paths automatically
Expose LSP call hierarchy over a lightweight textual call graph of
known functions and Name( call sites across the workspace.
- prepareCallHierarchy on func decl or call site
- incomingCalls / outgoingCalls with fromRanges
- smoke_lsp_call_hierarchy + test-lsp wiring
bux-lsp 0.7 indexes struct fields and enum variants and renames only the
right binding: .member / ::Variant / field-init, without clobbering locals.
- Member scan in analyzeFile; access kinds bare/dot/colon/field-init
- classifyRenameTarget: local | member | global
- smoke_lsp_rename_deep + test-lsp wiring
Bring selfhost C backend closer to bootstrap ownership and debug quality.
- Mark locals moved into struct fields / returns (no double Drop)
- Mangle Array/Set/Map/Channel field types so user structs fully emit
- Emit #line N from HIR line; BUX_DEBUG_FILE / BUX_NO_LINE controls
Track locals moved by value into struct fields, let bindings, or return
values so Array/Drop types are not freed while still owned by the target.
- hir_lower: movedOutLocals + markMovedOutFromAst + shouldSkipDrop
- Nexus: drop zeroing workaround; free headers after each request
- examples/move_field.bux regression for Box { items: arr }
Session 36: prevent UAF when Array is moved into a struct field (Nexus
headers), align selfhost cc flags with bootstrap debug/release, and add
workspace/symbol search to bux-lsp 0.6.
- Parser: zero headers after embedding so auto-drop is a no-op
- Request_WantsKeepAlive uses RequestHeader_Get again safely
- Selfhost: default -O0 -g; --release -O2 -DNDEBUG; BUX_CFLAGS
- LSP: workspace/symbol + smoke; version 0.6.0
Reuse TCP connections for multiple requests, honor Connection close,
and raise wrk health RPS from ~45k to ~80k+ on the same machine.
- Loop HandleConnection up to 1000 reqs/fd with Connection keep-alive
- RawRequest_WantsKeepAlive (HTTP/1.1 default; HTTP/1.0 needs keep-alive)
- Nexus 0.3.0 banner; benches note before/after RPS
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.
