   Hi @gtrak

   Thanks for the issue. I'm not sure to fully understand your use case, just in case you don't know it yet, Hurl is available as a standalone cli tool and as a Rust crate (a library in Rust world). You can totally build your own code / logic around the Hurl crate if the standalone CLi doesn't full fit your needs (you can make the parallel with curl / libcurl)

   A Rust sample code using the Hurl crate:

   use std::collections::HashMap;
   use hurl::runner;
   use hurl::runner::{Value, RunnerOptionsBuilder, VariableSet};
   use hurl::util::logger::{LoggerOptionsBuilder, Verbosity};
   use hurl_core::input::Input;
   
   // A simple Hurl sample
   let content = r#"
   GET http://localhost:8000/hello
   HTTP 200
   "#;
   
   let filename = Input::new("sample.hurl");
   
   // Define runner and logger options
   let runner_opts = RunnerOptionsBuilder::new()
       .follow_location(true)
       .build();
   let logger_opts = LoggerOptionsBuilder::new()
       .verbosity(Some(Verbosity::Verbose))
       .build();
   
   // Set variables
   let mut variables = VariableSet::new();
   variables.insert("name".to_string(), Value::String("toto".to_string()));
   
   // Run the Hurl sample
   let result = runner::run(
       content,
       Some(filename).as_ref(),
       &runner_opts,
       &variables,
       &logger_opts
   );
   assert!(result.unwrap().success);

   @gtrak please corret me but you mean something like maud for html you want to have a macro for inlining hurl files for hurl and then running the output of that?

   That looks cool! But, it's a different thing. The reply from @jcamiel is mostly what I was thinking about, except a macro could make it more typesafe with slots for specific query params, a-la https://github.com/kysely-org/kysely . I guess Maud is similar? But, the templates would stay in separate files so I could still run them with hurl CLI.

   @gtrak Thanks for trying to clarify, but I am still not sure what you mean tbh.
