Expand description

Direct port of struct parse_stack at Src/zsh.h:3099-3109. Used by parse_context_save / parse_context_restore (parse.c:295-355) to snapshot per-parse-call state so a nested parse (e.g. inside command substitution) doesn’t clobber the outer parse.

A second port of struct parse_stack exists at crate::ported::zsh_h::parse_stack (zsh.h:1066) using canonical Wordcode / Eccstr / struct heredocs types — that port is unused today and will become authoritative when Phase 9b (PORT_PLAN.md) wires wordcode emission. This local version uses the working-set shapes (Vec<HereDoc>, stubbed wordcode fields) suited to zshrs’s pre-wordcode AST architecture; the consolidation happens in P9b.

Fields§

§hdocs: Option<Box<heredocs>>

Pending heredocs awaiting body collection (canonical C linked-list shape). C: struct heredocs *hdocs (zsh.h:3100). Mirrors parse::HDOCS thread_local across nested parses.

§lex_heredocs: Vec<HereDoc>

!!! WARNING: NOT IN PARSE_STACK — Rust-only AST-glue !!! Snapshot of lex::LEX_HEREDOCS (the parallel Rust-only Vec carrying terminator / strip_tabs / quoted metadata). Saved/restored alongside the canonical hdocs so nested parses get a clean AST view. C’s parse_stack has no analog because C tracks terminator metadata implicitly via tokstr.

§incmdpos: bool

C: int incmdpos (zsh.h:3102).

§aliasspaceflag: i32

C: int aliasspaceflag (zsh.h:3103).

§incond: i32

C: int incond (zsh.h:3104).

§inredir: bool

C: int inredir (zsh.h:3105).

§incasepat: i32

C: int incasepat (zsh.h:3106).

§isnewlin: i32

C: int isnewlin (zsh.h:3107).

§infor: i32

C: int infor (zsh.h:3108).

§inrepeat_: i32

C: int inrepeat_ (zsh.h:3109).

§intypeset: bool

C: int intypeset (zsh.h:3110).
