Tutorial for run code file

[vnbubba]

Can you write a tutorial for running a code file as cpp, c file? Many thanks!

@vnbubba I don't really program in c or cpp, can you tell me what would you like to know about them?

This is my keymap for run a C file as vimscript but I don't know how convert it to lua.
nnoremap <F5> :w <bar> !g++ -std=c++17 -O2 -Wall % -o %:r && %:r.exe <CR>

Try

map('n', '<f5>', ':w <bar> !g++ -std=c++17 -O2 -Wall % -o %:r && %:r.exe <CR>', opts)

map is the conveneince function that AstroVim defines for you, the 'n' is the mode (the first 'n' in "nnoremap") and opts be default set "noremap" and "silent" (the "noremap" is the part after the first n of "nnoremap").

Your old version is actually not marked up as silent, so you can try to replace the opts with { noremap = true } -- if that is important to you.

May I missed something?

So the mapping worked and you only need to work on the code you want to call:-)

Can you add one of these packer for AstroVim? Thanks

There is no need to wait for AstroVim! You can just add all the plugins you need yourself:-)
