A fluid (fltk ui designer) file to Rust transpiler.
The minimum supported Rust version for 0.5 is 1.63.
You can run fl2rust on the command-line by installing using cargo-install:
$ cargo install fl2rust
Then run:
$ fl2rust <fl file>.fl > <output file>.rs
(A template repo usable via cargo-generate can be found here)
To automate things through cargo, you can use fl2rust as a library by adding it to your build-dependencies:
```toml
[dependencies] fltk = "1"
[build-dependencies] fl2rust = "0.5" ```
rust
// build.rs
fn main() {
use std::path::PathBuf;
use std::env;
println!("cargo:rerun-if-changed=src/myuifile.fl");
let g = fl2rust::Generator::default();
let out_path = PathBuf::from(env::var("OUT_DIR").unwrap());
g.in_out("src/myuifile.fl", out_path.join("myuifile.rs").to_str().unwrap()).expect("Failed to generate rust from fl file!");
}
```
version 1.0400 headername {.h} codename {.cxx} class UserInterface {open } { Function {makewindow()} {open } { FlWindow {} {open selected xywh {138 161 440 355} type Double visible } { Fl_Button but { label {Click me} xywh {175 230 95 45} } } } } ```
```rust // src/myuifile.rs
include!(concat!(env!("OUT_DIR"), "/myuifile.rs")); ```
```rust // src/main.rs use fltk::{prelude::*, *}; mod myuifile;
fn main() { let app = app::App::default(); let mut ui = myuifile::UserInterface::makewindow(); ui.but.setcallback(move |_| { println!("Works!"); }); app.run().unwrap(); } ```
There are several options:
- cargo install fltk-fluid
- Through a package manager.
- By building the fltk library yourself using cmake.
Version 0.4.4 adds i18n support via the tr! macro from the tr crate.
To enable it:
- In fluid, go to Edit->Project Settings...->Internationalization.
- Change the dropdown to use GNU gettext (which the tr crate supports in both forms gettext-rs and gettext).
- Add tr to you dependencies in you Cargo.toml.
- Add to your main.rs file:
```rust
extern crate tr; ``` - Initialize tr as described in the tr crate's documentation.
