# Install and try the new features
git clone https://github.com/su-mt/vscode-leetcode.git
cd vscode-leetcode
npm run compile
vsce package
code --install-extension vscode-leetcode-0.18.5.vsix
β¨ What's immediately available:
- π Daily Challenges in Explorer panel
- π§ Auto-generated C++ debug templates with real method names (πΉ See Demo)
- β‘ Smart caching for faster loading
- π― Type-aware variable generation (
vector<string>,vector<int>, etc.)
This fork extends the original LeetCode VS Code Extension with several powerful new features while maintaining full backward compatibility.
| Feature | Description | Status |
|---|---|---|
| π Daily Challenges | View and solve daily coding challenges directly in Explorer | β NEW |
| β‘ Smart Caching | 30-minute intelligent cache for optimal performance | β NEW |
| π§ Enhanced C++ Debug Templates | Auto-generated debug code with smart type detection and real method names (πΉ Demo) | β NEW |
| π Multi-endpoint Support | Full support for both LeetCode.com and LeetCode.cn | β ENHANCED |
| π Historical Tracking | Access to 30 days of daily challenge history | β NEW |
| π Translation Support | Localized content support for daily challenges | β NEW |
The Daily Challenges feature adds a dedicated section to your LeetCode Explorer, allowing you to:
- π View Today's Challenge - Instantly see the current daily coding problem
- π Browse History - Access up to 30 days of past daily challenges
- π― Track Progress - See which daily challenges you've completed
- β‘ Fast Loading - Smart caching ensures quick access without API spam
- π Global Support - Works with both international and Chinese LeetCode

The Enhanced C++ Debug Templates feature provides intelligent auto-generation of debug code for C++ problems, making testing and debugging significantly easier.
| Feature | Description | Example |
|---|---|---|
| π§ Smart Type Detection | Automatically detects vector<int>, vector<string>, string, int, bool, double |
vector<string> arr1 = {"flower", "flow", "flight"}; |
| π― Method Name Extraction | Extracts real method names from problem code | auto result = sol.twoSum(arr1, num2); instead of someMethod |
| π Parameter Count Matching | Uses only the required number of parameters based on function signature | Function expects 2 params β uses first 2 from test data |
| π HTML Entity Decoding | Properly handles " β " and other HTML entities |
Clean string values without encoding artifacts |
| π¨ Deduplication | Removes duplicate test data while preserving order | No repeated values in generated template |
| π Markdown Parsing | Extracts test data from problem descriptions automatically | Parses Input: nums = [2,7,11,15], target = 9 |
// @lc code=start
class Solution {
public:
vector<int> twoSum(vector<int>& nums, int target) {
}
};
// @lc code=end#include <iostream>
...<headers>...
using namespace std;
/*
* @lc app=leetcode id=1 lang=cpp
*
* [1] Two Sum
*/
// @lc code=start
class Solution {
public:
vector<int> twoSum(vector<int>& nums, int target) {
}
};
// @lc code=end
int main()
{
Solution sol;
// Π’Π΅ΡΡΠΎΠ²ΡΠ΅ Π΄Π°Π½Π½ΡΠ΅:
vector<int> arr1 = {2, 7, 11, 15};
int num2 = 9;
vector<int> arr3 = {3, 2, 4};
int num4 = 6;
vector<int> arr5 = {3, 3};
auto result = sol.twoSum(arr1, num2);
return 0;
}
Watch the Enhanced C++ Debug Templates in action:
The demo shows:
- π Automatic parsing of Input examples from problem description
- π§ Smart type detection (
vector<string>,vector<int>,int, etc.) - π― Real method name extraction (
twoSum,longestCommonPrefix, etc.) - β‘ Instant template generation with properly typed variables
- π§ Parameter count matching (only uses required number of params)
- Extract Test Data: Parses problem description for
Input:examples - Decode HTML: Converts HTML entities (
"β") to clean values - Detect Types: Analyzes values to determine C++ types
- Extract Method: Finds real method name and parameter count from code
- Generate Template: Creates properly typed variables and method call
// Arrays
vector<int> nums = {1, 2, 3}; // from [1,2,3]
vector<string> strs = {"a", "b", "c"}; // from ["a","b","c"]
// Primitives
string s = "hello"; // from "hello"
int target = 42; // from 42
double rate = 3.14; // from 3.14
bool flag = true; // from true
// Method calls with correct parameter count
auto result = sol.twoSum(nums, target); // Only uses required paramsgraph TD
