Release v0.5.1: IECStringVar / IECWStringVar read-through proxies#157
Merged
Conversation
…ar (#156) Without these proxies, user code reading a STRING / WSTRING pin has to write `name.get().c_str()` / `name.get().length()` / `name.get()[i]` for every read — `IECStringVar` would otherwise expose nothing but `get()` / `set()` / `operator=` to its consumers. Add `length()`, `c_str()`, and `operator[]` (read-only — returns char by value) on both `IECStringVar<MaxLen>` and `IECWStringVar<MaxLen>`, routed through the force-aware value (`forced_value_` when forcing is active, `value_` otherwise). This mirrors how `IECVar<T>::operator T()` already exposes the underlying numeric for force-respecting reads on numeric pins. Comparison operators (`operator==` / `operator!=`) are intentionally NOT proxied — the free-function overloads at the bottom of each header already cover every cross-class compare path, and adding member operators would risk overload ambiguity at ST call sites that currently bind to the free functions. Unlocks the openplc-editor / openplc-web c_blocks STRING/WSTRING standardization PRs — user C/C++ POU code can now read pins via plain `name.length()` / `name.c_str()` / `name[i]`.

Summary
Release v0.5.1 with the read-through proxy methods added to
IECStringVar/IECWStringVar(from #156).What's new since v0.5.0
length(),c_str(),operator[]proxies onIECStringVar<MaxLen>andIECWStringVar<MaxLen>, force-aware (route throughforced_value_when forcing is active,value_otherwise).name.length()/name.c_str()/name[i]syntax instead ofname.get().length()etc.Unlocks downstream
