Inject code fragments:

You can inject pieces of code that you frequently use in certain positions of the generated code file. Example: Standard library imports for each language can be put into a config. Leetup will pick it up and insert into the generated file.

Config:

Create ~/.leetup/config.json and customize according to your preference:

{
    "lang": "java",
    "inject_code": {
        "rust": {
            "before_code": ["use std::rc::Rc;", "use std::collections::{HashMap, VecDeque};", "use std::cell::RefCell;"],
            "before_code_exclude": ["// Test comment", "// Test code"],
            "after_code": "\nstruct Solution; \n\nfn main() {\n    let solution = Solution::$func();\n\n}\n",
            "before_function_definition": null
        },
        "java": {
            "before_code": "import java.util.*;",
            "before_code_exclude": ["// Test comment", "// Test code"],
            "after_code": null,
            "before_function_definition": null
        },
        "python3": {
            "before_code": "import math",
            "before_code_exclude": ["# Test comment", "# Test code"],
            "after_code": ["if __name__ = \"__main__\":", "    solution = Solution()"],
            "before_function_definition": null
        }
    }
}

Generated code looks something like this in Rust:

// @leetup=custom
// @leetup=info id=1 lang=rust slug=two-sum

/*
* [SNIP]
*/
// @leetup=custom

// @leetup=inject:before_code_ex
// Test comment
// Test code
// @leetup=inject:before_code_ex

// @leetup=code

// @leetup=inject:before_code
use std::cell::RefCell;
use std::collections::{HashMap, VecDeque};
use std::rc::Rc;
// @leetup=inject:before_code

impl Solution {
    pub fn two_sum(nums: Vec<i32>, target: i32) -> Vec<i32> {}
}
// @leetup=code

// @leetup=inject:after_code
// This is helpful when you want to run this program locally
// and avoid writing this boilerplate code for each problem.
struct Solution;

fn main() {
    let solution = Solution::two_sum();
}

// @leetup=inject:after_code

During testing and submitting to Leetcode, only the chunk of code between @leetup=code will be submitted:

// @leetup=inject:before_code
use std::cell::RefCell;
use std::collections::{HashMap, VecDeque};
use std::rc::Rc;
// @leetup=inject:before_code

impl Solution {
    pub fn two_sum(nums: Vec<i32>, target: i32) -> Vec<i32> {
    }
}

Others are ignored!

Hook up script for Pick:

Run scripts before/after code generation. It's useful when you want more ergonomics to move around the generated file e.g. create a directory, move the generated file to the directory, rename, etc. @leetup=working_dir will be replaced by working_dir in config.
@leetup=problem will be replaced by the current problem tile e.g. two-sum.

                "post_generation": ["mv @leetup=working_dir/@leetup=problem.java @leetup=working_dir/@leetup=problem/src/main/java/App.java"]
            }
        }
    }
