Vim [compile and] run shortcut
c, c++, python, shell, vim
Solution
Something like this would work. Just create filetype autocmd that map `<F4>` or whatever you want to save and compile and run the program. It uses exec to build the string and uses shellescape to escape the file name.
autocmd filetype python nnoremap <F4> :w <bar> exec '!python '.shellescape('%')<CR>
autocmd filetype c nnoremap <F4> :w <bar> exec '!gcc '.shellescape('%').' -o '.shellescape('%:r').' && ./'.shellescape('%:r')<CR>
autocmd filetype cpp nnoremap <F4> :w <bar> exec '!g++ '.shellescape('%').' -o '.shellescape('%:r').' && ./'.shellescape('%:r')<CR>
`%` is the current buffer filename. `%:r` is the buffer filename without extension
Problem
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: ``` when a shortcut key is pressed: if current_extension == 'c' then shell: gcc this_filename.c -o this_filename_without_extension if retcode == 0 then shell: ./this_filename_without_extension else if current_extension == 'cpp' then shell: g++ this_filename.cpp -o this_filename_without_extension if retcode == 0 then shell: ./this_filename_without_extension else if current_extension == 'py' then shell: python this_filename.py end if end key ``` I realise I might be asking a bit much but would love it if this was possible!
