Sublime Text launch separate command window (C/C++) - c++

I am trying to do all the programs in Programming in C by Stephen G. Kochan as an exercise and to familiarize myself with some of the finer details (I didn't go to school for computer science) of C (on a Windows 8 machine).
A lot of the book is simple programs and I'd like to enter the programs with Sublime Text (as opposed to Code::Blocks, which I have been using with openFrameworks). Is there an easy way to launch a separate command window for a program after it is compiled.
It's kind of hacky, but I changed the "run" version of build to launch the compiled program
"cmd": ["${file_base_name}.exe"]
but apparently, the Sublime Text documentation says that GUI's are suppressed.
What I want to do is launch a separate command prompt window. The primary reason is that scanf does not halt for input. Let me know if there is a quick workaround:
some workaround in Sublime Text ( a setting I'm not aware of)
how to change the build file to launch an actual window
some way to easily launch a separate window in C


{
"cmd": ["start", "cmd", "/c $file_base_name.exe"],
"selector": "text.c",
"shell": "true"
}
The cmd start command opens a new window of the command passed to it.
Note that to keep the window from closing immediately at the end of your programs, you'll have end them with system("pause"); or getch();, or replace /c with /k to keep cmd up.
EDIT: after more digging and debugging:
"cmd": ["start", "cmd", "/c", "$file_base_name.exe & pause"]
I had the same issue with Java, trying to create a Run Variant, and eventually came out with this:
"variants":
[
{
"cmd": ["start", "cmd", "/c", "java $file_base_name & pause"],
"name": "Run"
}
]


https://github.com/guilherme-p/Sublime-Build-Systems/blob/master/myC.sublime-build
{
"working_dir" : "$file_path",
"cmd": ["start", "cmd", "/k gcc $file_base_name.c -o $file_base_name.exe && $file_base_name.exe"],
"selector" : "source.c",
"shell" : true
}

Beginner Coder - Interact with Build Window in Sublime Text [duplicate]

I'm trying to get Sublime Text 3 to run a Python script. A simple two liner
var = raw_input("Enter something: ")
print("You entered " + var)
which asks for input, waits for it, then prints it out in windows console prompt.
Seeing the number of similar questions on the site, this is a problem for quite a number of users, so I went through those and tried ... stuff. Made a copy of exec.py file, commented that one line, made a new pythonw build file, tried messing about with the build file ... nothing seems to work.
In lack of a definite solution, how do you work with input using Sublime Text?

Sublime Text on its own cannot handle input via raw_input() (Python 2) or input() (Python 3). The same is true of other languages as well - Ruby's gets, Java's Scanner class, Node's readline class, scanf in C, cin in C++, etc. One short-term solution is to get Package Control if you don't already have it, then install SublimeREPL. It allows you to transfer or run part or all of your code through the running REPL. It may require some configuration of the Main.sublime-menu files to get your preferred interpreter to run properly. Alternatively, you can use the excellent Terminus plugin - details are at the bottom.
If the code you're running doesn't play well with SublimeREPL (for instance, you're using C/C++/Java/etc. and need to compile code before it runs), or you just want to run it independently of Sublime, you'll need to make your own build system. Save the following as Packages/User/Python_cmd.sublime-build:
Windows
{
"cmd": ["start", "cmd", "/k", "c:/python38/python.exe", "$file"],
"selector": "source.python",
"shell": true,
"working_dir": "$file_dir",
"env": {"PYTHONIOENCODING": "utf-8"}
}
changing the path to your Python executable as appropriate. Then, go to Tools -> Build System and select Python_cmd, and when you hit CtrlB to build, a new cmd window will open up with your file running. The /k option returns to the command prompt, without closing the window, after your program is done running so you can examine output, tracebacks, etc.
Please note that this build system is Windows-specific, as macOS and Linux do not have cmd. Build systems for those platforms are below.
macOS
If you are running OS X/macOS, the following build system will open your program in a new instance of Terminal. Save it as Packages/User/Python_Terminal.sublime-build. In my testing on macOS 10.15, the Terminal window didn't always come to the top when activated, so if you may need to look for it behind other windows.
{
"shell_cmd": "osascript -e 'tell app \"Terminal\" to do script \"cd $file_path && python3 -u $file\"'",
"working_dir": "$file_path",
"selector": "source.python",
"env": {"PYTHONIOENCODING": "utf-8"}
}
You may need to specify the path to your Python executable if it's not on your $PATH.
Linux
And finally, here is a build system for Linux. It was tested on Ubuntu, so if you use another distribution you'll need to ensure that gnome-terminal is installed. Save it as Packages/User/Python_shell.sublime-build. Once the program has finished running, hit any key to close the window.
{
"shell_cmd": "gnome-terminal --working-directory=$file_path -- bash -c 'python3 -u \"$file\" && read -n 1 -s -r'",
"working_dir": "$file_path",
"selector": "source.python",
"env": {"PYTHONIOENCODING": "utf-8"}
}
For reference, the Packages directory is the one opened when selecting Preferences → Browse Packages…:
Linux: ~/.config/sublime-text-3/Packages or ~/.config/sublime-text/Packages
OS X: ~/Library/Application Support/Sublime Text 3/Packages or ~/Library/Application Support/Sublime Text/Packages
Windows Regular Install: C:\Users\YourUserName\AppData\Roaming\Sublime Text 3\Packages or C:\Users\YourUserName\AppData\Roaming\Sublime Text\Packages
Windows Portable Install: InstallationFolder\Sublime Text 3\Data\Packages InstallationFolder\Sublime Text\Data\Packages
The exact path depends on version and whether or not you upgraded from Sublime Text 3.
I have only tested these build systems with Python, but they should work fine for any language. When modifying, just make sure that all the single and double quotes match up – you'll get errors or unexpected behavior if they don't.
UPDATE
There is a platform-independent plugin called Terminus that, among other things, provides a drop-in replacement for the default exec build system engine. It allows you to interact with your program in the build panel below your code. Once you've installed it from Package Control, create the following build system (again, for Python):
{
"target": "terminus_exec",
"cancel": "terminus_cancel_build",
"cmd": [
"/path/to/python", "-u", "$file"
],
"working_dir": "$file_path",
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
}
You'll need to adjust the path to your Python executable, as above. Make sure you read the documentation to find out all the other ways you can make use of this great plugin.

I found this by using the following in the console:

Follow this:

CTRL + P will open the Package control

Wait for a sec to pop up a search bar.
Type SublimeREPL and Click it.
It'll get installed in a few secs.
Then follow the following steps to run your program;
Tools >> SublimeREPL >> Python >> Python run Current File
It'll open a new window, where you can give your input and get the output.

You can use this sublime_build file which make run on cmd when you press ctrl+B .
Just go to tool ->sublime build->new build system and paste the below given as it is;
I have personally edited this sublime build file with my experience and believe me it has some good functionalities:
color changing when program terminates or ends
interactive output and input
console window automatic opening
pause after program finishes and wait till enter

"selector": "source.python",
"working_dir": "${file_path}",
"file_regex": "(.+):(\\d+): error: ",
"shell": true
}

Thanks #MattDMo for the answer, which doesn't require installing any plugin. But after I tried the command in macOS:
"shell_cmd": "osascript -e 'tell app \"Terminal\" to do script \"cd $file_path && python3 -u $file\"'",
I find it seems to run from background every time, which is not convenient.
So I tried another method: to use a temp.sh to run. Here is the command:
"cmd": ["zsh", "-c", "echo \"python3 ${file}\" > /tmp/tmp.sh ; chmod +x /tmp/tmp.sh ; open -a Terminal /tmp/tmp.sh ; sleep 2 ;rm /tmp/tmp.sh"],
This method will pop up a new window to the front, and it should be feasible on other platforms after a small modification, but I didn't try.

How to run C++ in command prompt from Sublime Text?

The build systems bundled with Sublime Text run the program in the small window below the text editor pane. This is inconvenient to some as user input cannot be taken in such a case.
What is the build system script to execute the program in a separate cmd window directly from Sublime Text?

Go to Tools > Build System > New Build System...' and paste the following in the file:
{
"cmd": ["g++.exe", "-std=c++11", "-o", "$file_base_name", "$file", "&&", "start", "cmd", "/c", "$file_base_name & echo. & echo. & pause"],
"shell": true,
"selector": "source.c++"
}
Save the file, and while compiling your C++ code from Sublime, choose the newly created build system from Tools > Build System

Run program in cmd mode after building from Sublime Text 2

I'm using Sublime Text 2 with MinGW as a build system to compile my c++ programs. I have the following build added to my Sublime:
{
"cmd": ["mingw32-g++.exe", "-o", "$file_base_name", "$file"],
"path": "C:\\Program Files (x86)\\MinGWStudio\\MinGW\\bin\\"
}
Now I want to run the program that I've just compiled in a cmd window (not in the Sublime console) What should I add to that command ?
Thank you.

A build system like the following will run your program in a new cmd window after you build it:
{
"cmd": ["mingw32-g++.exe", "-o", "$file_base_name", "$file"],
"path": "C:\\Program Files (x86)\\MinGWStudio\\MinGW\\bin\\",
"variants": [
{
"cmd": ["start", "cmd", "/k", "$file_base_name"],
"shell": true,
"name": "Run"
}
]
}
The "Run" name has special significance, it means that when you select this build system as your default, hitting CtrlB will compile your program, and then hitting CtrlShiftB will execute it. start is the command to start running a separate process, cmd is short for cmd.exe, the Windows command line program, and the /k option keeps the resulting window open after your program exits so you can see its output, run additional commands, or what have you.

For those trying this on MacOs (High Sierra) and Sublime 2, you might want to consider the next string in your build system:
{
"cmd": ["make", "${file_base_name}"],
"selector" : "source.c",
"variants": [
{
"cmd": ["/Applications/vice/x64sc.app/Contents/MacOS/x64sc $file_base_name"],
"shell": true,
"name": "Run"
}
]
}
This example will start Vice (the C64 emulator) installed in its specific location, which takes the file base name as an argument. Please note that I do not use "start", "cmd" or "/k".
