Struct SubInliner 

pub struct SubInliner { /* private fields */ }

Text-based Perl subroutine inliner.

Create one instance per source file and call [inline_call] (or its variants) to produce the inlined expression text.

Implementations

impl SubInliner

pub fn new(source: &str) -> SubInliner

Create a new inliner from Perl source text.

pub fn inline_call( &self, sub_name: &str, call_expr: &str, ) -> Result<String, InlineError>

Inline a single call to sub_name.

call_expr is the full call expression string, e.g. "add(3, 4)".

Returns the replacement text (the inlined expression), or an InlineError if the subroutine cannot be inlined.

pub fn inline_call_with_warnings( &self, sub_name: &str, call_expr: &str, ) -> Result<(String, Vec<String>), InlineError>

Like [inline_call] but also returns any warnings (e.g. side effects).

pub fn inline_call_with_outer_vars( &self, sub_name: &str, call_expr: &str, outer_vars: &[String], ) -> Result<String, InlineError>

Like [inline_call] but accepts a list of variable names that already exist in the outer scope, so collisions can be detected and renamed.
