PowerShell script file for updating packages

[pnachtwey]

I will need to have an easy way of excluding the problem packages

If you mean in the pip command line, you could replace it by something like

from pathlib import Path
import subprocess as sp
import sys

with Path('req0.txt').open('w') as ofile:
    sp.run([
        sys.executable, '-m', 'pip', 'list', '--outdated', 
        '--exclude', 'idna', '--exclude', 'mistune',
        '--exclude', 'tomli', '--format=freeze', '--user'], stdout=ofile)

Excellent! Your code is probably better than mine which isn't using the latest tricks. I will study your code and try it out.

import os
import subprocess
cmd="pip list --outdated --exclude astroid --exclude idna --exclude mistune --exclude mccabe --exclude wrapt --format=freeze --user > req0.txt"
os.system(cmd)
in_file = open("req0.txt", 'r')
out_file = open("req1.txt", 'w')
while True:
    in_line = in_file.readline()
    if not in_line:
        break
    out_line = in_line.replace("==",">=")   
    out_file.writelines(out_line)
    
in_file.close()
out_file.close()

try:
    if os.path.getsize("req1.txt") > 0:
        os,system("pip install --user --upgrade -r req1.txt")
        os.system("pip list --outdated > o.txt")
        os.system("pip check >> o.txt")
        o_file = open("o.txt","r")
        while True:
            o_line = o_file.readline()
            if not o_line:
                break
            print(o_line.strip())
        o_file.close()
    else:
        print("Nothing to update")
except OSError as e:
    print("File does not exist")

In any case. We have made improvements over the method at

BTW, isn't there a better way of excluding packages than using --exclude package for each package?
I looked and couldn't find any.

@Gribouillis
edit, wait! I did see where you edit the lines and update the packages!
Does python have something like sed and xargs? I couldn't find that either.

I have a bash and zsh script where I use xargs. It is much cleaner than my Python script.

Should I put this in a separate thread?

pip list --outdated --format=freeze --exclude idna --exclude mistune --exclude mccabe --exclude pycurl --exclude PyGObject --exclude dbus-python --exclude pycairo | sed 's/==/>=/g'| xargs pip install --upgrade --user
pip list --outdated
pip check
