Drupal Configuration Selector

A Python utility to selectively copy configuration files from a source directory to a target directory based on file prefixes.

Overview

This script helps you manage and transfer specific Drupal configuration files by:

• Reading a list of configuration file prefixes from a JSON file
• Identifying matching files in a source directory
• Copying selected files to a target directory
• Providing a TUI (Text User Interface) to manage the selection process

Requirements

• Python 3.6+
• curses library (built into most Python installations on Linux/Mac)

Installation and Setup

The script operates in the current working directory where you run it. It will create the following subdirectories if they don't exist:

• original_config/ - Place your source configuration files here
• config/ - Matched files will be copied here

Usage

1. Copy or move the script to your working directory (or use the full path to run it)
2. Place your source configuration files in the original_config directory
3. Run the script:

python3 config_selector.py

4. The script will create a default config_prefixes.json in the current directory if it doesn't exist
5. Use the TUI to manage your file selections and copy files

Hierarchical Navigation

The script organizes configuration files in a tree-like structure based on dot-separated prefixes:

• Files like field.storage.node.comment.yml are split into segments: field > field.storage > field.storage.node > etc.
• Use RIGHT ARROW to navigate deeper into a selected prefix
• Use LEFT ARROW to go back up one level in the hierarchy
• At each level, you see only the unique segments available at that level
• Each segment shows the total count of files under it
• Segments with children have a "▶" indicator
• You can perform actions (add, delete, select files) at any level in the hierarchy

TUI Navigation

The Text User Interface provides the following controls:

• UP/DOWN: Navigate through the list of prefixes
• LEFT/RIGHT: Navigate through the hierarchy tree (drill down/go back)
• SPACE: Toggle between matched and unmatched prefixes view
• ENTER: Select individual files from the selected prefix
• A: Add a new prefix (press ESC or Enter with empty input to cancel)
• O: Choose a prefix from the list of unmatched prefixes
• D: Delete the selected prefix (in matched view) or add the selected prefix (in unmatched view)
• C: Copy all matched files to the config directory
• S: Save the current list of prefixes to the JSON file
• Q: Quit the application

Individual File Selection

When you press ENTER on a prefix, a dialog opens that allows you to:

• In matched view: Select individual files to remove from the matching set
• In unmatched view: Select individual files to add to a matching prefix

Within the file selection dialog:

• Use UP/DOWN to navigate between files
• Press SPACE to toggle selection of a file
• Press ENTER to confirm your selection
• Press ESC to cancel

Configuration File

The script uses a JSON file to store prefixes. The default file is created at first run:

{
  "prefixes": [
    "put.your.prefixes.here"
  ]
}

You can modify this file directly or use the TUI to manage the prefixes.
