codeassign-cli

Command line interface for CodeAssign

Overview

This document describes the installation and usage of the CodeAssign CLI.

The CLI is used for testing some or all test cases of a given problem.

After you installed cae on your computer be sure to checkout our Hello World! Guide. And if you are having trouble with running your solution of Hello World! problem, be sure to checkout our solutions in 6 different languages: Python2, Python3, C, C++, Ruby, Bash and Java.

Installation

CodeAssign CLI works on Windows and Linux. We created stand-alone executables for these platforms so you don't have to worry about any dependantcies. Please, follow instructions for your platform. If your platform isn't listed or stand-alone executable version doesn't work on your computer, checkout universal instructions.

Windows

Just download cae.exe here. You can find this file in windows folder of this project.

Your cae.exe is now probably saved in your C:\Users\<YOUR USERNAME>\Downloads folder. If you now open cmd.exe in this folder, you will be able to run cae command. And if you do this you will get this message: No arguments given! Use "cae help" for instructions., and that's OK!

You are now ready to test your Hello World! solution. Be sure to check our Hello World! Guide if you have any trouble solving and evaluating this example.

Global installation

The above guide explains simplest and minimum steps that you have to do before running cae command. But now your CMD only knows about cae command if you position yourself in the folder where cae is located, i.e. probably your C:\Users\<YOUR USERNAME>\Downloads. If you want your CMD to know about your cae command in the whole system (i.e. you will be able to run cae anywhere in your CMD), this is what you need to do:

1. Copy cae.exe somewhere safe. We suggest you to create a CodeAssign folder in your C:\ drive and place cae.exe there. So now cae.exe will be located in C:\CodeAssign\cae.exe.

2. Open your Control Panel and go to System and Security > System.

3. On the left you will see Advanced system settings. Click on that and new window should open.

4. Now click on Advanced tab, and there at the bottom of the window you should see Environment Variables... button. Click on that button and new window should open.

5. In this window you should see two sections: User variables for <YOUR USERNAME> and System variables. In this second section find and select variable called Path.

6. With the variable Path selected click Edit... button (new window should open).

7. Depending on Windows version you have you will see either: nice table with some paths, or old and dirty text filed with paths separated with ;:

   • If you see a table, click on the New button and enter C:\CodeAssign\.
   • If you see old and dirty text field enter: ;C:\CodeAssign\. DON'T FORGET ; BEFORE YOUR PATH.

8. Click OK as many times as you can to exit from all windows.

9. Restart your PC.

10. Open your CMD and type cae. You should again see this message: No arguments given! Use "cae help" for instructions., and that's OK!

11. You are now ready to test your Hello World! solution. Be sure to check our Hello World! Guide if you have any trouble solving and evaluating this example.

Linux

1. Download or clone this project.

2. Copy linux/cae in /usr/local/bin folder

$ sudo cp linux/cae /usr/local/bin

3. Make sure cae is executable

$ sudo chmod +x /usr/local/bin/cae

4. You are now ready to test your Hello World! solution. Be sure to check our Hello World! Guide if you have any trouble solving and evaluating this example.

Universal

If your platform isn't listed above or the precompiled version we provide doesn't work on your computer, please follow these instructions.

1. Install python2.7.

2. Install pip.

3. Using pip install dependantcies:

$ pip install requests
$ pip install clint

4. You should now be able to run cae.py.

5. You are now ready to test your Hello World! solution. Be sure to check our Hello World! Guide if you have any trouble solving and evaluating this example.

Optional

After completing Universal steps above you can create stand-alone executable for your system. First install pyinstaller using pip:

$ pip install pyinstaller

Then for Linux or OSX run build_linux.sh script and for Windows run build_windows.bat script.

Your executable will be present in linux or windows folder.

Command

The keyword used is cae (CodeAssign evaluate):

cae {problemId} {pathToExecutable} {testCaseIds}(optional)  {additionalOptions}(optional)

Examples:

$ cae 476 main/main.exe
$ cae 476 main/main.exe 1,2,4
$ cae 476 main/main.exe 5-7 -less
$ cae 476 main/main.exe 4..6 -more

Parameters

{problemId} - required

The first parameter is the problemId, this is the id od the problem you want to test. This id can be found next to the problem name.

{pathToExecutable} - required

The second parameter is the path to your program executable. The path can be relative or apsolute.

Examples of correctly formated paths:

• /main/main.exe

• MyProgram\bin\main.exe

• C:/User/user/Desktop/main.exe

{testCaseIds} - optional

With this paremeter you can specify which test cases you want to run. If left blank, all test cases will be run.

Examples:

• 1,2,3
