# Project Euler Stats

Welcome to the docs for the Project Euler Stats plugin for Obsidian!

This plugin allows you to seamlessly integrate and display [Project Euler][projecteuler]
profile statistics directly within your Obsidian notes.
**Project Euler Stats** allows users to track their progress in solving problems on the Project Euler platform.
By using a simple command, users can generate a detailed profile that displays their profile, progress,
tasks, awards, and friends' rankings.

### Progress

### Tasks

Here, you can see your current tasks and how many problems you need to solve to reach the next level or ranking.

<img src="images/tasks.png" alt="tasks" width="500" />

### Personal tasks

You can add and track your personal tasks using the `euler-stats` code block format.
This allows you to monitor your progress on specific Project Euler problems directly or any another specific task
in your Obsidian notes.

````
```euler-stats
Solve problem 3; 0%
Solve problem 14; 15.6%
Solve problem 15; 27.1%
The Other personal task; 99.99%
```
````

Each task should be written in the following format:

```
<task>; <progress>%
```

- **`<task>`**: Your personal task.
- **`<progress>`**: The percentage of progress you have made on the problem (e.g., `0%`, `15.6%`, `100%`).

Personal tasks will be added before "standard" ones in the order they are declared.

## Syncing with Project Euler

By default, the plugin uses data from the **local cache** to avoid overloading the Project Euler website.
This ensures faster access to your stats and reduces unnecessary requests to the server.

### How to Sync Data

To update your data with the latest information from Project Euler, follow these steps:

1. Run the command **`Project Euler Stats: Sync with Project Euler`**.

	- This command will fetch the latest data from the Project Euler website and update your local cache.

   <img src="images/command.png" alt="Sync Command" width="500" />

2. **Success Message**:

	- If the sync is successful, you will see a notification:  
	  **`Successfully synced with Project Euler.`**

3. **Error Handling**:
	- If the sync fails, it usually means that your session has expired.  
	  **What to do if this happens:**
		1. Go to the [Project Euler website][projecteuler] and log in.
		2. Check the values of your cookies:
			- `PHPSESSID`
			- `keep_alive`
		3. Update these values in the plugin's settings:
			- Open the plugin settings in Obsidian.
			- Replace the old `SessionId` and `Keep-Alive` values with the new ones.
		4. Run the sync command again.

### Example Workflow

1. You’ve solved a new problem on Project Euler and want to update your stats in Obsidian.
2. Run the **`Project Euler Stats: Sync with Project Euler`** command.
3. If successful, your stats will now show the updated progress.
4. If the sync fails, follow the steps above to update your session cookies and try again.
