vscode - Extension Ripping for Dockerfile builds

Here is some simple code that will read your vscode.json file and rewrite it in a format that can be used in a Docker build (Dockerfile):

You will need this added to your Dockerfile so that it can install vscode extensions headless + the boiler plate code to install vs code.

Before you build if you get 'max depth exceeded' you may need to clean your images:

docker rmi -f $(docker images -a -q)

RUN DEBIAN_FRONTEND=noninteractive dpkg -i /files/vscode.deb
RUN DEBIAN_FRONTEND=noninteractive apt-get install -y rsync curl
RUN DEBIAN_FRONTEND=noninteractive curl -fsSL https://code-server.dev/install.sh | sh

Once you have these added then this python script will  'rip-n-write' your extension installs.

import re
# Press Shift+F10 to execute it or replace it with your code.
# Press Double Shift to search everywhere for classes, files, tool windows, actions, and settings.

with open('vscode.json', 'r') as g:
    mylines = g.readlines()

total_matches = ''

matches = re.findall('"id":"[^"]+"', mylines[0])
ccount = 0
for match in matches:
    if '.' in match:
        match = match.replace('"id":"', '')
        while '"' in match:
            match = match.replace('"', '')
        ccount += 1
        total_matches += match + ' '
        if ccount >= 8:
            print(f"RUN DEBIAN_FRONTEND=noninteractive code-server --install-extension {total_matches}")
            ccount = 0
            total_matches = ''

It will produce compounding install statements wrapping at every 8.  This is important as Dockerfile build depth's can break once your Dockerfile passes 250..
