How do I use input() to get the name of a new composer project from the user?

Question

I often start new projects in the same way. I guess it exists a way to be fast a starting a project.

For example: I am trying to start new composer project with the following function. I perfectly see the string 'New Project name: '.

But when I press enter, my cursor just goes on top of current file.

function! CreateProject()
    let new_name = input('New Project name: ')
    exec '!composer create-project foo/bar ' + l:new_name + ' 1.0.0'
endfunction

For concatenating string, you should use . instead of +.

I don't have composer installed, so instead of calling composer, I simply called the unix echo function like so :

exec '!echo ' . l:new_name . ' 1.0.0'

And it prints the entered name with the 1.0.0 after.
