Replace function body with todo!()

Usage

todo-replace <file-path> <csv-path>

Where is a comma separated value file with each row consists of two columns: function_name and body.

• function_name: The name of the function to be replaced.
• body: The new body of the function. If empty, it will be replaced with default { todo!() }. Note that body should begin and end with brackets {}, and after replacement, formatting may be off. You may need to run cargo fmt to fix it.

Example

fn foo() {
    println!(\"Old body\");
}

fn bar() {
    println!(\"Another body\");
}

foo,{ println!(\"New body\"); }
bar,{ println!(\"Updated body\"); }

Command:
