From b973ea107e910c36482f4831dda54451ff8851e3 Mon Sep 17 00:00:00 2001 From: "shoney.arickathil" Date: Fri, 14 Aug 2026 17:18:01 +0200 Subject: [PATCH] feat: program mode (argv + exit code); reject `+` on Text; nil compares by word MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit docs/examples/log-watcher now COMPILES AND RUNS: `wovm lw.wob watch app.log 2 1` tails a live file, classifies levels and fires its alert ("last entry is error, quiet for 2s"). corpus 71/0, woc 565/0, wovm gates green. - program mode: the entry is `fn main` taking nothing or one `multi Text`; runtime/src/main.c builds that list from the program's own arguments (not the program name, not the image path) and the entry's return value is the process exit code (low byte); the loader accepts a 0- or 1-arg free-fn entry - `+` on Text is now WO-E201 pointing at `..`. This was a memory-safety hole, not a style nit: the emitter lowered it to ADD on two heap pointers, and the workload's own `out = out + char_of(c)` produced a wild pointer that segfaulted the VM inside starts_with. Reported off confident types only - `x == nil` / `x != nil` lower to EQ (a word compare), never EQS: nil is the zero word and EQS dereferences its operands, so a nil guard would trap instead of answering - docs/examples/log-watcher: seven `+`-on-Text sites corrected to `..` (logtail sanitize, mcp header/body/carry assembly, supervisor detections line) — the sample was carrying the Haxe habit, and the language reserves `+` for arithmetic by doctrine - wovm CLI takes arguments after the image path (`wovm [args...]`) Co-Authored-By: Claude Opus 5 (1M context) --- compiler/src/emit.ml | 37 +++++- compiler/src/types.ml | 30 +++++ docs/00-status.md | 158 ++++++++++++------------ docs/examples/log-watcher/logtail.wo | 2 +- docs/examples/log-watcher/mcp.wo | 10 +- docs/examples/log-watcher/supervisor.wo | 2 +- runtime/src/loader.c | 7 +- runtime/src/main.c | 44 ++++++- 8 files changed, 191 insertions(+), 99 deletions(-) diff --git a/compiler/src/emit.ml b/compiler/src/emit.ml index 265524e..66c303e 100644 --- a/compiler/src/emit.ml +++ b/compiler/src/emit.ml @@ -1339,6 +1339,10 @@ let container_imm (p : pctx) (expected : Ast.field_ty option) (map : bool) : int | _ -> None) | None -> None +(* `nil` written literally on either side of a comparison — see emit_binary's + Eq/Ne cases for why the distinction matters. *) +let is_nil_lit (e : Ast.expr) : bool = match e.Ast.kind with Ast.NilLit -> true | _ -> false + let rec emit_expr (p : pctx) (f : fstate) (v : views) ~(dst : int) ?expected (e : Ast.expr) : unit = f.f_cur_line <- e.pos.line; (match e.kind with @@ -1600,14 +1604,26 @@ and emit_binary (p : pctx) (f : fstate) (v : views) ~(dst : int) (op : Ast.binop | Le -> simple op_le | Gt -> swapped op_lt | Ge -> swapped op_le - | Eq -> if is_text p f l || is_text p f r then simple op_eqs else simple op_eq + (* A comparison against `nil` is a WORD compare, never a content compare: + nil is the zero word, and EQS would dereference it as a `wo_str*` (the + VM's str_check traps on that, so an `x != nil` guard would trap instead + of answering).
