Something related to current_dir broke between versions 0.5.19 and 0.5.20

Using this build.rs:

use std::{error::Error, path::PathBuf};
use fl2rust::Generator;

fn generate_file(g:&Generator, out_path:&PathBuf, name:&str) {
  println!("cargo:rerun-if-changed=src/{name}.fl");
  let op = format!("{}", out_path.join(&format!("{name}.rs")).to_str().unwrap());
  // println!("cargo:warning=op [{op}]");
  g.in_out(&format!("src/{name}.fl"), &op).expect(&format!("Failed to generate {name}.rs!"))
}

fn main() -> Result<(), Box<dyn Error>> {
	use std::env;
	// println!("cargo:rerun-if-changed=src/main_ui.fl");
	let g = fl2rust::Generator::default();
	let out_dir = env::var("OUT_DIR").unwrap();
	//  println!("cargo:warning=out_dir [{out_dir}]");
	let out_path = PathBuf::from(out_dir.clone());

        println!("cargo:warning=current_dir [{:?}]", std::env::current_dir().unwrap().to_str());
	generate_file(&g, &out_path, "ui_main");

        println!("cargo:warning=current_dir [{:?}]", std::env::current_dir().unwrap().to_str());
        /// When a second .fl file is added to the project it fails (with version 0.5.20 and not with 0.5.19)
	generate_file(&g, &out_path, "ui_part");
  
  Ok(())
}

This is the ouput:

error: failed to run custom build command for `*****`

Caused by:
  process didn't exit successfully: `*****/target/debug/build/indicame-9e85cb3bbb282b5e/build-script-build` (exit status: 101)

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Modifying generate_file() to receive the full path of the source .fl

fn generate_file(g:&Generator, in_path:&PathBuf, out_path:&PathBuf, name:&str) {
  let infile = format!("{}", in_path.join(&format!("src/{name}.rs")).to_str().unwrap());
  println!("cargo:rerun-if-changed={infile}");
  let op = format!("{}", out_path.join(&format!("{name}.rs")).to_str().unwrap());
  println!("cargo:warning=op [{op}]");
  g.in_out(infile, op).expect(&format!("Failed to generate {name}.rs!"))
}

still fails and the second file (ui_part.rs) its almost empty (has some, i guess, boilerplate includes but not the generated one Obviously, downgrading to 0.5.19 solved the problem. Hope this helps

Thank you for the report. This should be fixed in 0.5.21. It required resetting the current dir after codegen.

Excellent
