Detailed Description

A parsed script, as a flat arena.

Children are int32_t indices, never pointers, and -1 means none. This is deliberate: the whole program copies by value into ScriptRunner::start() with no ownership question — matching HoldSpec's "a number that is passed in cannot go stale" discipline — and every size cap becomes a vector size check rather than a tree walk.

Member Data Documentation

◆ block_items

std::vector<int32_t> fsw::script::ScriptProgram::block_items

Statement indices, grouped into contiguous [begin, end) block ranges.

Definition at line 162 of file StateScript.hpp.

◆ exprs

std::vector<Expr> fsw::script::ScriptProgram::exprs

Definition at line 160 of file StateScript.hpp.

◆ max_depth

uint32_t fsw::script::ScriptProgram::max_depth = 0

Definition at line 169 of file StateScript.hpp.

◆ slugs

std::vector<SlugRef> fsw::script::ScriptProgram::slugs

Every slug reference in SOURCE ORDER, with spans.

The rename path rewrites these; the pressure subscriber derives its subscribe list from the Ns::PtSensor ones.
