using nimble for package management

[jseb]

Hello,

I have installed some packets with nimble. I wonder if it's possible to do a 
global update after a nimble refresh.

For the moment i use this homemade command:
    
    
    find ~/.nimble/pkgs/ -type d -maxdepth 1  | for i in $(cut -f1 -d'-'); do 
nimble install $(basename "$i"); done
    
    
    Run

It has several problems, though:

1) when a package exists, i get an error. Seeing the message, an anwer seems 
required, but actually doesn't wait and throw an error. I don't complain 
because otherwise my script would be stalled, but that's strange anyway:
    
    
     Installing x11@1.1
        Prompt: x11@1.1 already exists. Overwrite? [y/N]
    io.nim(141)              raiseEOF
    Error: unhandled exception: EOF reached [EOFError]
    
    
    Run

2) when an update is available, the old package is not removed:
    
    
    ~$ ls ~/.nimble/pkgs/nico-0.* -lhd
     07-07-20 19:42 /home/jseb/.nimble/pkgs/nico-0.2.7/
     11-07-20 15:20 /home/jseb/.nimble/pkgs/nico-0.3.1/
    
    
    
    Run

I could add a cleaning package in my script. But what if a package has a 
dependancy on an older package, which should not be removed, then ?
    
    
    ~$ ls ~/.nimble/pkgs/sdl2* -lhd
     11-07-20 15:48 /home/jseb/.nimble/pkgs/sdl2-2.0.2/
     11-07-20 15:50 /home/jseb/.nimble/pkgs/sdl2_nim-2.0.12.0/
     05-07-20 14:53 /home/jseb/.nimble/pkgs/sdl2_nim-#head/
    
    
    Run

(i didn't dare removing one of them…)

Thank you.
