Note

Windows Defender may warn "not commonly downloaded". This is normal, click "Keep" to continue.

Creating your first project

After opening the IDE, try writing and running a Hello World program to verify installation.

#include <bits/stdc++.h>
using namespace std;
int main() {
    cout << "Toi yeu gai alime!" << '\n';
    return 0;
}

Steps:

Paste the code above into the editor
Press Ctrl + S to save as hello.cpp
Press F11 to compile and run
The output will appear in the terminal below

Tip

Use F9 to compile only, F10 to run only, F11 for both.

System Requirements

Component	Minimum	Recommended
OS	Windows 10 64-bit	Windows 11
CPU	Intel Core i3 / AMD Ryzen 3	Intel Core i5 / AMD Ryzen 5 or better
RAM	4GB	8GB+
Disk Space	1.5GB (free space)	2GB+

Compiler Settings

Sameko uses GCC 16 with pre-configured compile options.

Standard	Description
C++98	Legacy, rarely used today
C++11 / C++14	Stable, widely used, supports auto, lambdas
C++17	(Default) Gold standard for Competitive Programming
C++20	Adds Ranges, Concepts, Modules
C++23	Adds std::print, std::expected
C++26	(Beta/Experimental) Latest features in development

Common Compiler Flags

-O2 - Optimize for speed, use when submitting to Codeforces
-Wall - Show warnings, helps find bugs
-g - Add debug information

Warning

Don't use -O2 when debugging as optimized code is harder to trace.

Keyboard Shortcuts

Shortcuts help you code faster.

Shortcut	Action
`F9`	Compile
`F10`	Run
`F11`	Compile & Run
`Ctrl` + `N`	New file
`Ctrl` + `O`	Open file
`Ctrl` + `S`	Save file
`Ctrl` + `Shift` + `A`	Format code (AStyle)
`Ctrl` + `J`	Toggle terminal
`Ctrl` + `\`	Split editor

Open Sameko IDE
Go to a problem page (e.g., Codeforces) and click the extension icon
Test cases will be automatically added to the IDE

Tip

After parsing test cases, click Run All Tests to run all and see AC/WA/TLE results.

Snippets

Snippets help you type code templates faster. Sameko has built-in snippets and you can add your own.

Built-in Snippets

cp - Competitive programming template with bits/stdc++.h
bfs - BFS template
dfs - DFS template
segtree - Segment Tree
dsu - Disjoint Set Union

Type the prefix and press Tab or Enter to expand the snippet.

Adding custom snippets

Go to Settings > Snippets to open the snippet editor. Each snippet has a prefix (trigger) and body (code to expand).

Troubleshooting

IDE won't open

Right-click Sameko.exe, select Properties, check "Unblock" at the bottom, then Apply.
