This code provides a UI for managing a data processing pipeline using tkinter. The PipelineManager class handles creating and updating the pipelines, while the PipelineManagerUI class handles the UI components. The input and output of each step are folders on disk, and the code is designed to be modular and easily extendible.

The user can specify a workspace, create new pipelines with a default name, and specify a date range for the pipeline. The application shows the status of each step in the pipeline, and the pipelines in the workspace are still in the view after the application closes and is reopened.

Please note that the actual implementation of the data processing steps is not provided in this code, as this would depend on the specific requirements and data sources involved. You need to implement the run_pipeline method in the PipelineManager class to include the data processing logic.

To enhance the UI to display the status of the pipelines and allow users to run each step, I've added a new function, run_step_dialog, to choose a step to run from the steps that have not been completed yet. I also added a button to open this dialog for the selected pipeline in the treeview.

Here's the updated code:

import os
import json
import time
import tkinter as tk
from tkinter import filedialog, ttk
from datetime import datetime

# ... (Keep the PipelineManager class unchanged)

class PipelineManagerUI:
    def __init__(self, master, pipeline_manager):
        self.master = master
        self.master.title("Data Processing Pipeline Manager")
        self.master.geometry("600x400")

        self.pipeline_manager = pipeline_manager

        self.create_widgets()

    def create_widgets(self):
        self.create_menu()
        self.create_pipeline_tree()
        self.create_controls()

    def create_menu(self):
        # ... (Keep the create_menu function unchanged)

    def create_pipeline_tree(self):
        # ... (Keep the create_pipeline_tree function unchanged)

    def create_controls(self):
        control_frame = tk.Frame(self.master)
        control_frame.pack(side="bottom", fill="x")

        if not selected_item:

# ... (Keep the main function unchanged)

Now, the UI displays the status of each pipeline, and the user can run each pipeline step by step. Please note that you still need to implement the actual data processing logic in the run_step function inside the run_step_dialog method, as this depends on your specific requirements and data sources.

[SelwynChan]

To display the steps run for each pipeline, we can add a new column in the treeview to show the completed steps. To show the path to the workspace and make it linkable to the pipeline's folder, we can create a label widget displaying the workspace path, and bind an event to open the folder in the file explorer.

Here's the updated code:

import os
import json
import time
import webbrowser
import tkinter as tk
from tkinter import filedialog, ttk
from datetime import datetime

# ... (Keep the PipelineManager class unchanged)

class PipelineManagerUI:
    def __init__(self, master, pipeline_manager):
        self.master = master
        self.master.title("Data Processing Pipeline Manager")
        self.master.geometry("700x400")

        self.pipeline_manager = pipeline_manager

        self.create_widgets()

    def create_widgets(self):
        self.create_menu()
        self.create_workspace_label()
        self.create_pipeline_tree()
        self.create_controls()

    def create_menu(self):
        # ... (Keep the create_menu function unchanged)

    def create_workspace_label(self):
        workspace_label = tk.Label(self.master, text=f"Workspace: {self.pipeline_manager.workspace}", cursor="hand2")
        workspace_label.pack(side="top", fill="x", padx=5, pady=5)
        workspace_label.bind("<Button-1>", self.open_workspace_folder)

    def open_workspace_folder(self, event):
        webbrowser.open(self.pipeline_manager.workspace)

    def create_pipeline_tree(self):
        tree_container = tk.Frame(self.master)
        tree_container.pack(side="top", fill="both", expand=True, padx=5, pady=5)

        self.tree = ttk.Treeview(tree_container, columns=("status", "completed_steps"), show="headings")
        self.tree.column("status", width=100, anchor="center")
        self.tree.column("completed_steps", width=350, anchor="w")
        self.tree.heading("status", text="Status")
        self.tree.heading("completed_steps", text="Completed Steps")
        self.tree.pack(side="left", fill="both", expand=True)

        for pipeline in self.pipeline_manager.pipelines.values():
            status = "Not started"
            if len(pipeline["completed_steps"]) == len(pipeline["steps"]):
                status = "Completed"

            self.tree.insert("", "end", text=pipeline["name"], values=(status, ", ".join(pipeline["completed_steps"])))

        scrollbar = ttk.Scrollbar(tree_container, orient="vertical", command=self.tree.yview)
        scrollbar.pack(side="left", fill="y")
        self.tree.configure(yscrollcommand=scrollbar.set)

    def create_controls(self):
        # ... (Keep the create_controls function unchanged)

    def create_pipeline_dialog(self):
        # ... (Keep the create_pipeline_dialog function unchanged)

    def run_step_dialog(self):
        # ... (Keep the run_step_dialog function unchanged)

# ... (Keep the main function unchanged)

Now, the UI displays the completed steps for each pipeline in a new column in the treeview, and the workspace path is shown at the top of the window. Users can click the workspace path to open the pipeline's folder in the file explorer. Note that you might need to install the webbrowser package if you haven't already.
