Struct HeredocAssembler 

pub struct HeredocAssembler { /* private fields */ }

Assembles a heredoc body part-by-part, applying POSIX <<- leading-tab stripping to the source rather than to the materialized result.

Leading tabs that were literal in the heredoc source are stripped; a tab that arrives via an interpolation ($var value, $(cmd) output) at line start is preserved, because POSIX strips tabs from source lines before parameter expansion (bash agrees). Callers feed literal segments through push_literal and interpolated values through push_interpolated. With strip_tabs == false this is a plain concatenation.

This replaces materialize-then-strip_leading_tabs, which ate tabs that came from a variable’s value.

Implementations

impl HeredocAssembler

pub fn new(strip_tabs: bool) -> Self

pub fn push_literal(&mut self, literal: &str)

Append a literal source segment, stripping leading tabs at line starts when in <<- mode.

pub fn push_interpolated(&mut self, value: &str)

Append an interpolated value verbatim. The interpolation terminates the leading-tab run for the current source line — even when it expands to empty — so a following literal tab on the same source line is mid-line and kept.

pub fn into_string(self) -> String
