Vim [compile and] run shortcut

Question

Basically what I want is a keyboard shortcut in vim that lets me [compile and] run the currently being edited C, C++ or Python program. In psuedocode:

Answer 1

I wanted to find a shortcut too. But I didn't want to use autocmd for some reason. I used bash script. I was already using a bash script to compile and run my C/C++ codes. So, I thought, why don't I use a bash script and use it in fltplugin file for C and C++. I made two separate bash scripts. One for C and one for C++. Here is the script for C (For C++, it is also similar just change the compiler to clang++/g++, std=c2x to std=c++20 and $filename.c to $filename.cpp),

filename=$1
compiler=clang-10
if [ $2 ]; then
    if [ $2 == "-v" ]; then
        FLAGS="-g -Wall -Wextra -pedantic -std=c2x"
    fi
else
    FLAGS="-Wall -Wextra -pedantic -std=c2x"
fi

$compiler $FLAGS $filename.c -o $filename -lm

return_value=$?

if [ $return_value -eq 0]; then
    if [ $2 ]; then
        if [ $2 == "-v" ]; then
            valgrind ./$filename
            rm $filename
        fi
    else
        ./$filename
        echo
        echo "[process exited $return_value]"
        rm $filename
    fi
fi

Saved it as run. I made it executable for all users,

$ chmod 777 run

I moved it to my user bin directory.

$ mv run ~/bin

If you dont have a user bin directory, make on. Go to your home directory, and make a directory named bin.

$ cd ~
$ mkdir bin

Then move the run (or whatever name you gave to your script) file to the bin directory.

$ mv run ~/bin

Let's move on. Then I made a c.vim file in ~/.vim/after/ftplugin directory. And add two new key remaps to the c.vim file.

nnoremap  :vertical bo term run %:r

# This will run my code with valgrind
nnoremap  :vertical bo term run %:r -v 

Here are some screen shots,

Clicking F9 shows me the output screen in a vim buffer,

Clicking F2 shows me the output using valgrind in a vim buffer

You can do same for C++, just make a cpp.vim file in ~/.vim/after/ftplugin directory. And make another run file (like run_cpp), save it in your user bin(~/bin) file. Make some custom key bindings, and you are good to go.
