imgui-rs/xtask/src/flags.rs

//! xflags is a bit jank still, but pretty nice compared to pico_args, and
//! compiles a billion times faster than clap/structopt.
//!
//! When you modify stuff in the args_parser block, you'll get compile errors.
//! to fix these:
//! 1. run `env UPDATE_XFLAGS=1 cargo build -p xtask` in the shell.
//! 2. this will error, but should update the contents of this file that exists
//!    between `// generated start` and `// generated end`.
//! 3. If it has trouble updating, try deleting everything from this file that
//!    isn't part of the `xflags!` macro (all the generated code), or ping me
//!    (@thomcc).
