Executes leetcode testcases and submits your solution through CLI interface
Disclaimer : This is not an official Leetcode tool. I am not affiliated with Leetcode in any way. This tool is not endorsed by leetcode.
-
Install rust from here to compile the source code.
-
Clone the repository and install the binary.
git clone https://github.com/dvishal485/leetcode-runner-cli.git cd leetcode-runner-cli cargo install --path .
-
Setup environment variable
LC_COOKIE
with your leetcode session cookie.You can get your session cookie by logging in to leetcode and inspecting the cookie in your browser's developer tools.
Make sure to put your cookie in double quotes.
export LC_COOKIE="csrftoken=abcdefgh;LEETCODE_SESSION=ijklmnopqrstuvwxyz;"
-
Execute the tool and verify your authentication.
leetcode-runner-cli -a
leetcode-runner-cli [FLAGS] [OPTIONS <option>]
Commands | Description | Arguments |
---|---|---|
-h, --help |
Prints help information | - |
-V, --version |
Prints version information | - |
-a, auth |
Authenticate with leetcode | - |
-d, daily |
Fetch daily challenge question | - |
-q, question |
Question title / url to fetch | [question_title] |
-r, run |
Execute file with default testcases | [file_to_run] |
-rt, run-custom |
Execute file with custom testcases | [testcase_file] [file_to_run] |
-s, submit |
Submit solution to leetcode after passing testcases | [file_to_submit] |
-fs, fast-submit |
Submit solution to leetcode | [file_to_submit] |
If you fetch the question from the CLI (using -d
or -q
), then tool will automatically add the required changes in the boiler plate code.
But if you are using your own code, then you need to make the following changes :
The file you submit to leetcode shouldn't have driver code like main function or struct definition. But no need to manually remove it. The tool will automatically remove the driver code and submit the solution to leetcode. All you need to do is put the delimiters #LCSTART
and #LCEND
in your solution file in comments, and place leetcode problem link anywhere in the file.
For example :
struct Solution;
// #LCSTART
impl Solution {
pub fn two_sum(nums: Vec<i32>, target: i32) -> Vec<i32> {
// real magic here
}
} // #LCEND https://leetcode.com/problems/two-sum/
fn main() {
// can have anything which may assist you
}
- In case link is not found, the tool will exit with error message for the same.
- In case start delimiter is not found, the tool will run till the end delimiter.
- In case end delimiter is not found, the tool will run till the end of file.
- In case both start and end delimiters are not found, the tool will default to the whole file.
-
Fetch question koko-eating-bananas
leetcode-runner-cli -q koko-eating-bananas
OR
leetcode-runner-cli -q https://leetcode.com/problems/koko-eating-bananas/
-
Run src/main.rs with default testcases for question koko-eating-bananas
leetcode-runner-cli -r ./src/main.rs
-
Run src/main.rs with custom testcase file
leetcode-runner-cli -rt ./testcase.txt ./src/main.rs
-
Submit src/main.rs to leetcode
leetcode-runner-cli -s ./src/main.rs
Note : This will first execute the default testcases and then submit the solution to leetcode only if the testcases pass as a preventive measure to avoid submitting wrong solution.
-
Submit src/main.rs to leetcode without running testcases
leetcode-runner-cli -fs ./src/main.rs
- Code file should have the link of question in the comments for the following examples.
- If you don't specify file location then the tool will search for code in the current directory and use it by default.
- If there are multiple files, then the tool will use file named
main
or the first file it finds in case there is nomain
file.
So, in the above examples, you can simply do cd ./src
and then run the following commands :
- Execute with custom testcases :
leetcode-runner-cli -rt ./testcase.txt
- Execute with default testcases :
leetcode-runner-cli -r
- Submit :
leetcode-runner-cli -s
- Submit without running testcases :
leetcode-runner-cli -fs
This is a generic module that can be used to run any language. It only needs a mapping to the language
on leetcode and extension
of the file.
Currently, the following languages are added by default : Rust, Python3, Cpp, Java, C, Javascript, Go, Kotlin, Swift, Typescript, Csharp, Ruby, Scala, PHP, Racket, Erlang, Elixir, Dart.
More languages can be added manually as per requirement by changing enum in the src/file_parser/language.rs
file.
