[PATCH v21 0/1] MR10461: vbscript: Implement IDispatch::GetTypeInfo for class instances.
by Francis De Brabandere (＠francisdb) May 1, 2026

May 1, 2026

Implement GetTypeInfo on vbdisp_t (VBScript class instances) by returning an ITypeInfo that reports the class name via GetDocumentation(MEMBERID_NIL) and exposes public methods and properties via GetFuncDesc, GetVarDesc, GetNames, GetIDsOfNames, and GetTypeAttr. This makes TypeName() return the actual class name (e.g. "MyClass") instead of falling back to "Object". This is partially based on previous work by @jsm174 at https://github.com/jsm174/libwinevbs/blob/fbc4d2a17a2da8196d50805f7ae289406… -- v21: vbscript: Implement IDispatch::GetTypeInfo for class instances. https://gitlab.winehq.org/wine/wine/-/merge_requests/10461

[PATCH v3 0/3] MR10783: vbscript: Match native semantics for empty parens on non-callable values
by Francis De Brabandere (＠francisdb) May 1, 2026

May 1, 2026

Native VBScript distinguishes bare member access from with-parens access and rejects the latter on non-callable values: - `obj.scalarProp()` / `obj.arrayProp()` on a class instance variant property — error 5 (Invalid procedure call) - `x()` on a Dim scalar variable — error 13 (Type mismatch) - `arr()` on a Dim array — error 9 (Subscript out of range) -- v3: vbscript: Delegate do_icall is_call branch to variant_call. vbscript: Raise illegal-func-call on empty parens of class variant property. vbscript/tests: Cover empty parens on properties, Dim variables, and arrays. https://gitlab.winehq.org/wine/wine/-/merge_requests/10783

[PATCH v23 0/6] MR10515: Draft: vbscript: Bind local variables, class properties, and loop variables at compile time.
by Francis De Brabandere (＠francisdb) May 1, 2026

May 1, 2026

Resolve identifiers to direct indices during compilation instead of doing runtime `wcsicmp` string scans in `lookup_identifier()`. This adds new opcodes that access local variables, function arguments, class properties, and loop variables by index, eliminating the linear string comparison overhead for the most common cases. **New opcodes:** - `OP_local` / `OP_assign_local` / `OP_set_local` - read/write local vars and args by index - `OP_local_prop` / `OP_assign_local_prop` / `OP_set_local_prop` - read/write class properties by index - `OP_step_local` / `OP_incc_local` - For-loop step/increment with indexed counter - `OP_enumnext_local` - For-Each iteration with indexed loop variable This mirrors jscript's `OP_local` / `bind_local()` optimization (`dlls/jscript/compile.c`) and addresses the FIXME in `lookup_identifier()` noting that class property access should be bound at compile time. Names that cannot be resolved at compile time (globals in Execute/ExecuteGlobal code, dynamic vars, host objects) continue to use the existing string-based path. The last commit also adds a fast path for SAFEARRAY iteration that bypasses the `IEnumVARIANT` COM vtable dispatch and copies elements directly from the array data, eliminating one intermediate `VariantCopy` per iteration. ### Local variable / argument / class property access (1M iterations, 10 reads per iteration) | Benchmark | Windows (VM) | Wine master | Wine (7 commits) | **Speedup** | vs Windows | |-----------|-------------|-------------|-------------------|---------|------------| | Local vars | 156 ms | 413 ms | 234 ms | **1.8x** | 1.5x slower | | Arguments | 171 ms | 357 ms | 231 ms | **1.5x** | 1.4x slower | | Class props | 265 ms | 393 ms | 226 ms | **1.7x** | 0.9x (faster!) | ### For-loop variants (10M iterations) | Benchmark | Windows (VM) | Wine master | Wine (7 commits) | **Speedup** | vs Windows | |-----------|-------------|-------------|-------------------|---------|------------| | Empty For | 117 ms | 370 ms | 270 ms | **1.4x** | 2.3x slower | | For + assign | 203 ms | 613 ms | 430 ms | **1.4x** | 2.1x slower | | Do-While manual | 437 ms | 646 ms | 513 ms | **1.3x** | 1.2x slower | | For Step 2 | 62 ms | 370 ms | 271 ms | **1.4x** | 4.4x slower | | Nested For | 125 ms | 387 ms | 268 ms | **1.4x** | 2.1x slower | | For local Sub | 109 ms | 294 ms | 251 ms | **1.2x** | 2.3x slower | | For R8 counter | 203 ms | 2,812 ms | 2,529 ms | **1.1x** | 12x slower | | For-Each array | 7 ms | 286 ms | 62 ms | **4.6x** | 8.9x slower | The remaining 4-13x gap vs Windows in For-loops is from `VarAdd`/`VarCmp` going through full `VariantChangeTypeEx` machinery (including locale alloc/free per call). A separate MR ([!10528](https://gitlab.winehq.org/wine/wine/-/merge_requests/10529)) adds I2/I4 fast paths in oleaut32 that bring integer loops within 1.2-1.9x of Windows when combined with this branch. -- v23: vbscript: Bind class properties at compile time. vbscript: Bind For-loop variables at compile time. vbscript: Factor out do_for_step and do_incc from interp_step and interp_incc. vbscript: Bind local variable assignments at compile time. vbscript: Factor out assign_local_var from assign_ident. vbscript: Bind local variables and arguments at compile time. https://gitlab.winehq.org/wine/wine/-/merge_requests/10515

[PATCH v7 0/1] MR10459: vbscript: Implement DateDiff built-in function.
by Francis De Brabandere (＠francisdb) May 1, 2026

May 1, 2026

Implement DateDiff(interval, date1, date2 [, firstdayofweek [, firstweekofyear]]) with support for all interval types: yyyy, q, m, y, d, w, ww, h, n, s. For yyyy/q/m the difference is computed from calendar fields via VarUdateFromDate. For d/y the day number difference is used. For w it is the day difference integer-divided by 7 (not affected by firstdayofweek). For ww it counts week boundary crossings based on firstdayofweek. For h/n/s the dates are converted to the respective unit and truncated before subtracting. Returns VT_I4 (Long). Null date arguments return Null; null interval or null firstdayofweek/firstweekofyear return VBSE_ILLEGAL_NULL_USE. -- v7: vbscript: Implement DateDiff built-in function. https://gitlab.winehq.org/wine/wine/-/merge_requests/10459

[PATCH v16 0/1] MR10363: vbscript: Support assignment to chained array index expressions.
by Francis De Brabandere (＠francisdb) May 1, 2026

May 1, 2026

Handle expressions like x(0)(1) = 5 where the left side of an assignment is a call expression whose inner expression is also a call (not a direct member). The compiler now evaluates the inner expression as a read, then emits a new OP_assign_call opcode to assign to the resulting array element or default dispatch property.
