[Bug] `Err` value: Error("expected square brackets") #1152

Closed kthecoder closed 1 year ago

kthecoder commented 1 year ago

Describe the bug

I've tried running the generator on:

  1. https://github.com/iotaledger/iota.rs
  2. https://github.com/iotaledger/wallet.rs
  3. https://github.com/signalapp/libsignal

All give the same error of 

[ERROR] panicked at 'called `Result::unwrap()` on an 
`Err` value: Error("expected square brackets")', 
C:\Users\.cargo\registry\src\github.com-1ecc6299db9ec823\flutter_rust_bridge_codegen-1.72.1\src\config\opts.rs:41:62

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

I don't know if its something I am doing wrong or what. I followed the guides on adding in all necessary dependencies and installed LLVM, Visual Studio C++ development. I added build runner, ffigen, ffi, and flutter_rust_bridge_codegen; to the pubspec

To Reproduce

  1. Create a Flutter Library Template
  2. Add in either libsignal, wallet.rs or iota.rs to a rust folder
  3. Add in the tutorial dependencies and installations to run the generator
  4. Run the generator on the rust code to create the bindings

Expect a generated output to complete

Hi! Thanks for opening your first issue here! :smile:

fzyzcjy commented 1 year ago

Hi, it would be great to show more logs, e.g. RUST_BACKTRACE=1

kthecoder commented 1 year ago

Do I just put env::set_var("RUST_BACKTRACE", "1"); inside of the lib file? Cause that isn't working.

fzyzcjy commented 1 year ago

IMHO just do sth similar to RUST_LOG=debug

kthecoder commented 1 year ago

I must be tired I just realized these are environment variables.

Ok so the problem seems that, syn crate fails to parse the rust code. I am not sure, maybe this is a bug of syn, or your code has syntax error?

kthecoder commented 1 year ago

Looking at Signals Bindings Builder for Swift they build the entire library using cbindgen which produces Swift Bindings for C.

Flutter_Rust_Bridge also uses cbindgen. The rust project I am trying to create bindings for consists of a set of multiple libraries using a Workspace. There is no main lib.rs file. Furthermore, each lib.rs in each crate contains pub's pointing to actual implementations.

What is the difference in steps to generate the bindings?

fzyzcjy commented 1 year ago

The difference is that, frb firstly uses syn to parse rust files. cbindgen is a later step.

The folder seems a bit complex, so I am not sure current frb implementation understands it correctly. Feel free to PR! I guess you only need to modify some parser https://github.com/fzyzcjy/flutter_rust_bridge/tree/master/frb_codegen/src/parser

kthecoder commented 1 year ago

If its not too much of a bother, I have a few questions.

So the goal is, someone comes along and just wants to use some random unknown Rust project. The solution being just generate all possible bindings for whatever is found.

To do so, the only change that needs to be made is the ability to iterate over all possible connected files.

FRB runs on just a single file. So is the only necessary change to find all possible files connected by pub mod, use crate or mod ? And if file exists, run the current FRB on each of the files? And where for instance create::path::to::{foo1, foo2 as foo3} only parse those defined functions/classes?

Would this be the function to change? Parser -> mod.rs:

pub fn parse(source_rust_content: &str, file: File, manifest_path: &str) -> IrFile {
    let crate_map = Crate::new(manifest_path);

    let mut src_fns = extract_fns_from_file(&file);
    src_fns.extend(extract_methods_from_file(&file));
    let src_structs = crate_map.root_module.collect_structs_to_vec();
    let src_enums = crate_map.root_module.collect_enums_to_vec();
    let src_types = crate_map.root_module.collect_types_to_pool();
    let src_types = topo_resolve(src_types);

    let parser = Parser::new(TypeParser::new(src_structs, src_enums, src_types));
    parser.parse(source_rust_content, src_fns)
}

Or best to create a second function and a cmd flag?

fzyzcjy commented 1 year ago

IIRC, currently we only have a limited feature: https://cjycode.com/flutter_rust_bridge/feature/lang_external.html#types-in-other-crates. By searching the related PRs you may know more design choices why it was implemented like that (IIRC simplicity?).

However, feel free to enhance the library to support automated generation of arbitrary crates - that looks like a quite useful feature!
