# Daily Weight Prompt

Daily Weight Prompt is an Obsidian plugin that asks for your current body weight and saves it into today's daily note frontmatter.

It is designed for people who already use Daily Notes or Periodic Notes and want a fast, low-friction way to record weight as part of their daily workflow.

## Features

- Prompts for your weight automatically after Obsidian finishes loading.
- Adds a command to open the prompt manually at any time.
- Finds or creates today's daily note through the standard Daily Notes integration.
- Saves the value into daily note frontmatter under a configurable property name.
- Accepts integer and decimal input such as `87`, `87.4`, or `87,4`.
- Lets you skip entry for the day and stores `null` in the frontmatter property.
- Can avoid showing the automatic prompt more than once per day.

## Requirements

This plugin depends on the Daily Notes integration used by:

- Obsidian Daily Notes
- Periodic Notes

If that integration is not available, the plugin cannot resolve or create today's daily note.

## How it works

When the plugin runs, it checks whether today's daily note already exists.

- If the note exists, the plugin updates its frontmatter.
- If the note does not exist, the plugin attempts to create it first.
- If you enter a value, that number is written to the configured frontmatter property.
- If you choose to skip, the property is written as `null`.

Example frontmatter:

```yaml
---
weight: 87.4
---
```

## Settings

The plugin currently exposes two settings:

- `Weight property name`: the frontmatter property to update. Default: `weight`
- `Ask only once per day`: prevents the automatic startup prompt from appearing again on the same day

## Command

- `Ask current weight now`: opens the weight prompt manually

## Installation for development

1. Clone this repository into your vault plugins folder:
   `VaultFolder/.obsidian/plugins/daily-weight-prompt/`
2. Install dependencies:

3. Start the development build:
   `npm run dev`
4. Reload Obsidian and enable the plugin in **Settings -> Community plugins**.

## Build for production

Run:

```bash
